Subject: [PATCH 02/61] perf(responses): reuse measured entry strings for the
 state snapshot (#6360)

Carries the snapshot half of #4732: keep the per-entry strings measured by selectSnapshotEntries and join them, so a snapshot write serializes entries once instead of twice. Output is byte-identical; a pinned-bytes regression test covers it.

Subject: [PATCH 03/61] feat(codex): pick the model for each LazyCodex agent
 role (carry #6262) (#6366)

Carries #6262 by @LilMGenius: a role model picker for omo (Codex / LazyCodex) agent roles. It adds a Codex-tab section, GET/PUT /api/codex-agent-roles and ocx agent roles. It is gated on LazyCodex detection (the omo@sisyphuslabs plugin plus the lazycodex-install.json receipt). The edit changes only the root model pin and optionally mirrors it to ~/.omo/omo.jsonc. The maintainer follow-up refuses an invalid role TOML and keeps filesystem paths out of write errors.

+# 261001 omo (Codex / LazyCodex) carry series
+
+LilMGenius opened three stacked PRs that let opencodex manage the model of each Codex agent role installed by LazyCodex (#6262), size roles and auto-assign models (#6269), and suggest a delegation model on the Subagents page (#6274). They could not land as fork PRs: the readiness gate needs the author's local-validation attestation, fork CI never ran its test shards, and `hygiene` flagged an unsponsored management-API surface. This unit lands the same work as three maintainer carry PRs in dependency order, each crediting the author, each merged only after its exact head passes hosted CI.
+
+## Loop spec
+
+- **Loop archetype:** satisfy-spec (verifier defines done: exact-head required CI green, then squash merge).
+- **Trigger:** maintainer request (2026-10-01) to research omo and merge LilMGenius's work via cxc-loop.
+- **Goal:** #6262, #6269 and #6274 content on `dev`, originals closed with credit.
+- **Non-goals:** no behavior changes beyond the contributor heads; no Pi omo or OpenCode omo changes; no #6348 or other JEV work; no release or promotion. **No local test suites or typecheck** (maintainer instruction); hosted CI is the only execution evidence.
+- **Verifier:** `gh pr checks <carry PR> --required` on the exact head SHA (reads every required job of that head, including test shards, typecheck, structure, privacy, file-size ratchet, hygiene, enforce-target). Local: `git diff --check` and `git merge-tree --write-tree origin/dev HEAD` (textual union only).
+- **Stop condition:** all three carries merged and originals closed, or a blocker that needs maintainer direction.
+- **Memory artifact:** this unit (000–030 docs) and the session goalplan `lilmgenius-omo-codex-lazycodex-role-model-series`.
+- **Expected terminal outcomes:** DONE (three merges); BLOCKED (CI failure needing design change, union conflict that changes behavior); NEEDS_HUMAN (security-review objection).
+- **Escalation condition:** a required job fails for a reason that is not a mechanical carry fix; a behavior decision beyond the contributor heads; a security-review objection. Shared gate 4 compatibility repairs (including a byte-for-byte ratchet move) are pre-authorized and do not escalate.
+- **Resource bounds:** none set by the user beyond the host goal.

+- **omo variants** (maintainer review 2026-09-30 01:47 on #6262): Pi omo (senpi, `~/.omo/agent`, existing omo tab), OpenCode omo (oh-my-opencode, untouched), Codex omo (LazyCodex). The series is now scoped to LazyCodex; Pi omo has no diff against `dev`.
+- **LazyCodex detection verified against LazyCodex source** (`~/developer/codex/161_lazycodex`): the installer writes `lazycodex-install.json` into the plugin root (`plugins/omo/scripts/install-flow.mjs:4` `INSTALL_SNAPSHOT_FILE`, `plugins/omo/dist/cli/index.js:99259`); the plugin is installed with `codex plugin add omo@sisyphuslabs` (README). `src/clients/lazycodex.ts` requires `plugins."omo@sisyphuslabs".enabled = true` and a receipt under `plugins/cache/sisyphuslabs/omo/<ver>/`, matching the Codex plugin cache layout.
+- **Open review threads** re-checked at heads 6262 `ada7ec14b1`, 6269 `6c97ca9a4f`, 6274 `b180fcec0a` (architect D2–D4): unreadable `omo.jsonc` (handled by `readOmoRoleModels` → `unreadable`), escaped quoted keys (decoded, undecodable refused), multiline closing quotes (scanner consumes them), mirror retry (`retryMirror`), DelegationSuggest live region (mounted polite region). All fixed with regressions; threads are resolved on landing with a pointer.
+- **Topology:** strictly stacked 6262 ⊂ 6269 ⊂ 6274, merge-base `961a4b569` (26 behind `dev` at `0328373fb8`); `git merge-tree` of 6274 vs `dev` is clean. Layer sizes: L1 18 commits / 39 files, L2 19 / 43, L3 12 / 38. All 49 commits authored by `LilMGenius <smsmeee@naver.com>`.
+- **Ratchet:** no touched file is in `tests/fixtures/file-size-baseline.json` caps; i18n catalogs are exempt. Uncapped files fail at 2,000 lines; `src/server/management/agent-settings-routes.ts` reaches 1,941 at 6274 (watch in wp3).

+
+- D1 sequential layer cherry-pick onto landed dev — **accepted**: each PR diff is its own layer; author identity stays on every commit; squash body adds `Co-authored-by: LilMGenius <smsmeee@naver.com>`.
+- D2/D3/D4 findings already fixed — **accepted**; no extra code; resolve threads with pointers on landing.
+- D5 union gates (ratchet 2,000-line ceiling, test-layout maps, i18n parity, structure ownership, route registry) — **accepted**; enforced by hosted CI, watched by hand at carry time.
+- D6 preserve recent dev changes in shared files — **accepted**; conflicts resolved by keeping both sides, never wholesale contributor tree.
+- D7 merge-dev-into-contributor-head alternative — **rejected**: post-squash parent overlap makes later layers re-carry earlier commits.
+- D8 #6274 scope is general Codex delegation, not LazyCodex-only — **accepted as intended**: the author states it configures Codex delegation defaults; the maintainer asked to merge the whole series.
+- Reflection: see 001_reflection.md.

+## Security review note
+
+## Gates shared by every carry (r2, after architect reflection)
+
+1. **Pinned inputs.** Replay immutable full-SHA ranges only: wp1 `961a4b569512bd568106c4ea67a21a346e002779..ada7ec14b1b089f461e43e208d54750591fd26f9`, wp2 `ada7ec14b1b089f461e43e208d54750591fd26f9..6c97ca9a4fdec6c59901fa115be341d9cc590a15`, wp3 `6c97ca9a4fdec6c59901fa115be341d9cc590a15..b180fcec0a4c3ff63b9f230acc79e5f029bb6cea`. Before replay assert `git rev-parse refs/omo/<n>` still equals the upper SHA; a moved contributor head stops the carry for re-plan.
+2. **Fresh base.** `git fetch origin dev` immediately before branching; wp2/wp3 assert `git merge-base --is-ancestor <previous squash SHA> origin/dev`.
+3. **Conflict reconciliation.** Keep both sides semantically: one entry per key in i18n catalogs, layout maps and route registry; no duplicated registrations; never take the contributor file wholesale.
+4. **Compatibility repairs are allowed** when hosted CI fails for a mechanical union reason (test-layout registration, ratchet 2,000-line ceiling via a byte-for-byte move into a sibling module, i18n key parity, structure ownership). Such a repair is a separate commit named "fix(carry): …", listed in the PR body, and does not change behavior. Anything else escalates.
+5. **CI receipt.** Record in the PR body/comment and in this unit: head SHA, base SHA, `gh pr checks <n> --required` output with every required job `pass`, and a coverage assertion that the expected jobs actually ran and succeeded at that head — every `test` shard, `typecheck`, structure, privacy scan, file-size ratchet, `hygiene`, `enforce-target`, and GUI lint/tests when `gui/` changed; a job that is absent, skipped or cancelled fails this gate. Also record the CI run id and attempt for the `pull_request` event at that head. Immediately before merge, re-read the head SHA and required checks; merge with `gh pr merge <n> --squash --match-head-commit <sha>`.
+6. **Publication.** PR template fully filled; GUI screenshots linked from the contributor's existing pr-assets (no image committed to the branch); squash body ends with `Co-authored-by: LilMGenius <smsmeee@naver.com>`; maintainer-integration record (MAINTAINERS.md "maintainer integration": actor lidge-jun admin, exact-head CI evidence) posted as a PR comment.
+7. **Security review.** Before merge, an independent read-only security reviewer (fresh subagent, not the architect) reviews the exact carry head for its surfaces — management-API route admission and sibling guard, file writes under `$CODEX_HOME/agents` and `~/.omo/omo.jsonc` (path validation, atomicity, no secret logging), and the loopback self chat-completion (admission header, response bounds). Its verdict (PASS / FINDINGS) is bound to the head SHA and recorded in the PR comment and in this unit. FINDINGS block merge until fixed or explicitly dispositioned; an unresolved objection is NEEDS_HUMAN. Owner authorization (2026-10-01) covers the merge decision, not the review.
+8. **D8 evidence.** #6274 author comment 2026-09-30T07:35: "Delegation suggest configures Codex delegation defaults, so it stays unscoped from the omo variants"; the maintainer's 2026-10-01 instruction covers the whole series.
+9. **Maintainer-objection gate.** The originals carry two `CHANGES_REQUESTED` reviews by lidge-jun (2026-09-30 01:44 stack split, withdrawn by the 01:47 review; 01:47 omo-variant scoping). The author addressed the variant scoping in `e9ea34661`, `7c81640d0`, `b91537a75`, `d7a4f91a7` (#6262) and the matching #6269/#6274 commits. When each carry PR opens, dismiss both reviews on its original with a message citing those commits and the carry PR; immediately before each merge run `scripts/ci/assert-mergeable-review.sh --maintainer-integration <carry PR>` and require exit 0. Any other maintainer objection is NEEDS_HUMAN.
+10. **Base binding.** `pull_request` CI tests the merge of head and base at trigger time. Immediately before merge: `git fetch origin dev`; if `origin/dev` moved past the base recorded in the CI receipt, merge `origin/dev` into the carry branch (no force push), push, and repeat gates 5, 7 and 9 on the new head; for gate 7 the security reviewer inspects the incoming dev delta and re-attests the new head (a short "no security impact" verdict bound to that SHA suffices). Merge only when the receipt base equals current `origin/dev`.
+
+## Security review note (surfaces)
+
+Surfaces: management API routes (`/api/codex-agent-roles`, auto-assign, `/api/injection-model/suggest`), file writes under `$CODEX_HOME/agents` and `~/.omo/omo.jsonc`, and a loopback self chat-completion (`src/lib/local-chat-completion.ts`). No credential storage or OAuth change. Sibling instances refuse writes. Each carry PR states this and requests the MAINTAINERS.md security review explicitly.

+
+## Steps
+
+1. `git switch -c codex/omo-lazycodex-role-models origin/dev` (this branch also carries this unit's docs).
+2.

On conflict reconcile per gate 3: `dev` additions in i18n catalogs, `scripts/test-layout/layout.json`, `tests/fixtures/test-layout-expected.json`, `structure/clients/integrations.md`; `src/lib/jsonc.ts` (the series only modifies it; it exists unchanged on `origin/dev` and at the pinned base, blob `dda3c392`. An earlier accidental trial cherry-pick in the main checkout hit a modify/delete conflict only because that checkout's local `dev` was stale at `9177663665`; the trial was aborted and the checkout restored).
+3. `git diff --check origin/dev...HEAD`; `git merge-tree --write-tree origin/dev HEAD` must be clean.
+4. Push; open PR to `dev` titled `feat(codex): pick the model for each LazyCodex agent role (carry #6262)` with the PR template filled, the three-variant table and screenshots from #6262 (LilMGenius pr-assets SHA `d0a29e1c` links), "Carried from #6262 by @LilMGenius", `Co-authored-by: LilMGenius <smsmeee@naver.com>`, Verification "local suites not run (maintainer instruction); hosted CI at exact head", security-review request, and the maintainer-integration record.
+5. Wait for every required check on the exact head; fix mechanical carry failures only (escalate otherwise).
+6. Squash-merge with the co-author trailer; resolve #6262 open threads with a pointer; leave #6262 open until wp3 closes all three.

+## omo variants

+"omo" names three products, and each surface here serves exactly one of them:
+
+| Variant | Its own evidence | opencodex surface |
+| --- | --- | --- |
+| Pi-based omo (senpi engine) | `~/.omo/agent`, or `OMO_CODING_AGENT_DIR` / `SENPI_CODING_AGENT_DIR` / `PI_CODING_AGENT_DIR` (`omoAgentDir()`) | the `omo` file integration and tab, `providers.opencodex` in `models.json` |
+| Codex-based omo (LazyCodex) | `[plugins."omo@sisyphuslabs"] enabled = true` in `$CODEX_HOME/config.toml` plus `lazycodex-install.json` in an installed copy under `$CODEX_HOME/plugins/cache/sisyphuslabs/omo/<version>/` (`detectLazyCodex()` in `src/clients/lazycodex.ts`) | role model pins and the omo.jsonc mirror below, on the Codex tab |
+| OpenCode-based omo (oh-my-opencode) | its config under OpenCode | none; nothing here reads or writes it |
+
+`~/.omo` alone identifies none of them: Pi-based omo and LazyCodex both use it.
+
+### omo (Codex / LazyCodex) role models
+
+Separate from the `models.json` provider integration above, and only when `detectLazyCodex()`
+reports LazyCodex installed, `src/clients/omo-role-models.ts`
+mirrors a dashboard or `ocx agent roles set` pick into `codex.agents.<role>.model` of
+`~/.omo/omo.jsonc`, which LazyCodex 5.1.1 and later reads. The home is resolved the way omo
+resolves it: `HOME`, then `USERPROFILE`, then the OS home. This write has no ownership record,
+snapshot, or journal. It changes one value the user just chose and leaves every other key as it
+was, re-serialized with the file's indentation, line endings, and BOM.
+
+It never creates the file and never writes one it would damage: a missing file reports
+`absent`, a document that is not an object or whose `codex`, `codex.agents`, or role entry is
+not an object reports `invalid`, and a file containing any `//` or block comment reports
+`skipped_comments`, because re-serializing JSONC would drop those comments. The management
+response carries that status and the dashboard shows it; the role TOML write described in
+[subagents](../subagents.md#per-role-model-pins) is not rolled back by a skipped mirror.
+An explicit `null` in any of those three places counts as not an object. A file that exists but
+cannot be read lists as `unreadable`, so the role table still loads, and a save reports
+`write_failed` for the mirror.
+Without LazyCodex, `GET /api/codex-agent-roles` answers `lazycodex.detected: false` with no roles
+and without opening omo.jsonc, and `PUT` answers 409 `lazycodex_not_detected` before touching a
+role file.

+### Per-role model pins
+
+Codex overrides a child's spawn-time model with the root `model` key of
+`$CODEX_HOME/agents/<role>.toml`, so that pin decides which model a role runs on.
+`src/codex/agent-role-models.ts` is opencodex's only writer into those files, and it writes only
+that one key, only when a user picks a role's model in the dashboard's omo (Codex / LazyCodex)
+section on the Codex tab (`PUT /api/codex-agent-roles/{role}`) or with `ocx agent roles set`,
+and only while LazyCodex is detected. No sync, startup, or
+catalog path calls it, and opencodex never creates, repairs, or removes a role file.
+
+- The key is located by the same TOML-aware scan the pin reader uses
+  (`locateTomlModelKey` in `src/codex/subagent-model-fallback.ts`), so a `model =` line inside
+  the instructions multiline string is never read or edited. A key under a table header is not
+  the root pin.
+- An existing one-line string value is replaced inside its span; every other byte, including
+  quote style when the new value allows it, trailing comments, line endings, and a leading BOM,
+  is kept. A missing key is inserted after the leading comment block. A non-string value is
+  refused rather than duplicated.
+- The original file and the edited result must both parse as TOML; otherwise the write is
+  refused with `invalid_role_file` and the file keeps its bytes, so an edit can never turn a
+  role Codex rejects into one it loads. Other write failures answer a fixed `write_failed`
+  message without the filesystem path or owner details.
+- The role name must equal a listed `*.toml` stem, which is also the path-traversal check. The
+  target must be a regular file owned by the running user; the replacement is atomic and does
+  not follow a symbolic link.
+- The same pick is mirrored into LazyCodex's `codex.agents.<role>.model`; that half belongs to
+  [client integrations](clients/integrations.md#omo-codex-lazycodex-role-models). The role file is written first
+  and stands even when the mirror is skipped.
+
+Sibling instances refuse the write, because it reaches the shared `CODEX_HOME`.

Subject: [PATCH 04/61] feat(codex): auto-assign LazyCodex role models by
 sizing each role (carry #6269) (#6367)

Carries #6269 by @LilMGenius: Auto-assign for omo (Codex / LazyCodex) agent roles. One sizing call asks a model the user already has to sort each role into a capability tier and an effort level, never naming a model. A deterministic mapper then turns each tier into a concrete model and reasoning effort. POST /api/codex-agent-roles/auto-assign only proposes changes. Applying a proposal goes through the existing PUT. The CLI form is ocx agent roles suggest [--apply]. Maintainer follow-ups: sizing failures now return only a fixed category or HTTP status, the effort writer keeps the role-TOML validation from #6366, and two React Doctor warnings are fixed.

+**Re-verification at P (2026-10-01, dev `a6114b62ed`).** wp1 landed as #6366 with a maintainer security fix (`70f696593c`): `writeCodexAgentRoleModel` validates the role TOML before and after the edit (`invalid_role_file`), and the route answers a fixed `write_failed` message. A probe replay showed the second L2 commit `a0e3ac8d39` (role `model_reasoning_effort` write) conflicts with that fix in `src/codex/agent-role-models.ts` and `tests/routing/codex-agent-role-models.test.ts`. Resolution (gate 3, union, no behavior dropped from either side):
+- `AgentRoleModelErrorCode` keeps `invalid_effort` and `invalid_role_file` (plus the existing codes).
+- `writeCodexAgentRoleModel`: `assertValidRoleToml(role, before, "before")` → `withModel = setTomlRootModel(...)` → `after = effort === undefined ? withModel : setTomlRootReasoningEffort(withModel, validateAgentRoleEffort(effort))` → unchanged check → `assertValidRoleToml(role, after, "after")` → write.
+- Tests: keep the invalid-TOML refusal test and both new effort tests.
+Later L2 commits are replayed after this resolution; any further conflict in these two files follows the same union rule. Because the effort path now also passes the after-validation, gate 7 re-review covers the effort writer.
 4. PR `feat(codex): auto-assign LazyCodex role models by sizing each role (carry #6269)`; same template/credit/security/integration records; screenshots from #6269 body.

+### Auto-assign
+
+Auto-assign is part of omo (Codex / LazyCodex): it sits above the role table in that section and
+exists only while LazyCodex is detected. Without it the dashboard shows neither, the API answers
+409 `lazycodex_not_detected`, and `ocx agent roles suggest` is refused.
+
+Auto-assign proposes a model for every role at once. opencodex asks your
+default Codex model (the root `model` in Codex `config.toml`) one question: for each role, given its
+description and the start of its instructions, which capability tier (fast, standard or frontier)
+and how much reasoning (glance, measured, thorough or exhaustive) does it need? That model never
+picks a model. opencodex then picks the cheapest model from your picker list that reaches the tier:
+
+- Models listed under `codexRoleTiers` in the opencodex config (`{ "fast": [...], "standard": [...], "frontier": [...] }`)
+  have that tier.
+- Other models with a known price are ranked by price and split evenly across the three tiers. With only
+  one or two priced models, the dearest is frontier and the other, if any, is standard.
+- Models with no price and no listed tier are never proposed. List them to include them.
+
+Each proposal shows the model, the tier, the reasoning effort, a one-line reason, and what would move
+it up or down. A role the model could not size clearly is shown as not sized, with the reason, and
+cannot be applied. Nothing is written until you press Apply on a row or Apply all. Applying uses the
+same save as picking by hand, and also rewrites the role's `model_reasoning_effort` when the file already has
+one. The effort is placed on the chosen model's own levels: its lowest, its default, one above the
+default, or its highest.

+ *    Three or more split evenly across the three tiers by rank, cheapest in fast. Fewer than three
+ *    cannot fill every tier, so the ranking is anchored at the top: the dearest is frontier,
+ *    because it is the strongest model on offer, and each cheaper one sits one tier lower. One

+ *    fast role steps up to the cheapest model and a standard role keeps it instead of jumping to
+ *    the dearest, which keeps every role on the cheapest sufficient model on offer.
+ * 3. Otherwise it is unclassified and never proposed.
+ *
+ * A role gets the cheapest sufficient model: the lowest tier at or above what it was sized for,
+ * then the lowest price, then the picker's own order.
+ *
+ * Effort binds to positions on the chosen model's ladder: glance is the floor, measured is the
+ * model's default or the middle rung, exhaustive is the ceiling, and thorough is the rung above
+ * measured when that rung is not the ceiling. When no such interior rung exists, thorough
+ * collapses to the nearer of measured and the ceiling; the two are equally near, and the one

 Sibling instances refuse the write, because it reaches the shared `CODEX_HOME`.
 
+### Role model auto-assign
+
+`POST /api/codex-agent-roles/auto-assign` (dashboard Auto-assign, `ocx agent roles suggest`) proposes a
+model for every role and writes nothing. It belongs to omo (Codex / LazyCodex): without
+`detectLazyCodex()` it answers 409 `lazycodex_not_detected` before reading the body or calling a model,
+the same refusal as the PUT. Applying a proposal is the ordinary
+`PUT /api/codex-agent-roles/{role}`, now with an optional `effort`. The work splits in two on purpose:
+
+- **Sizing is one model call.** `src/codex/role-sizing.ts` holds the rubric (ported from the MIT-licensed
+  modelchk skill, cited in the file) as the system prompt, the neutral vocabulary
+  (`fast|standard|frontier`, `glance|measured|thorough|exhaustive`), and the validator. Each role sends its
+  name and the first 1500 characters of `description` plus `developer_instructions`; a role with neither
+  is not sent. The call goes through the proxy's own `/v1/chat/completions` via
+  `postLocalChatCompletion` (`src/lib/local-chat-completion.ts`, shared with the routed vision describer), on
+  the root `model` of Codex `config.toml` unless the caller names one. An answer that is not the strict JSON
+  shape, a missing role, or a field outside the vocabulary leaves that role **unsized** with the reason;
+  nothing is guessed. Keys beyond the five answer fields are ignored, and all five stay required. The
+  sizing model never names a model.
+- **Mapping is deterministic code.** `src/codex/role-auto-assign.ts` draws candidates from
+  `subagentSelectableModels` (the same list the role picker renders) and tiers them: `codexRoleTiers` in the
+  opencodex config first, then price rank (input plus output per 1M tokens). Three or more priced models
+  split evenly across the three tiers. Fewer are anchored at the top, the dearest frontier and each cheaper
+  one a tier lower, so one is frontier and two are standard and frontier; fast is the tier left empty,
+  which keeps a standard role on the cheaper model. Unpriced, unmapped models are never proposed. A role
+  gets the lowest sufficient tier, then the lowest price. Effort binds to ladder positions of the chosen
+  model (floor, default or middle, the rung above, ceiling), collapsing inside the range; it is proposed
+  only for a role whose file already sets `model_reasoning_effort`, and written by the same span-preserving
+  editor as `model`, located by the same TOML-aware scan.
+
+The sizing call is injectable (`completeCodexRoleSizing` on the management deps), so route tests answer it
+without a provider. Sibling instances refuse the preview too: it sits under the refused
+`/api/codex-agent-roles` prefix, and its proposals could not be applied there anyway.
+
 `injectionModel` and `injectionEffort` are shared selections with two independent consumers.
 `multiAgentGuidanceEnabled` controls only OpenCodex-authored delegation guidance.
 `syncCodexSubagentDefaults` is a separate, default-off opt-in that applies the selected values to

Subject: [PATCH 05/61] feat(subagents): suggest a delegation model by sizing
 the work (carry #6274) (#6389)

Carries #6274 by @LilMGenius. It adds Suggest next to the Subagents page's "Model to call first": the user describes the delegated work, one sizing call applies the role-sizing rubric, and the deterministic mapper proposes the cheapest sufficient offered model and an effort. POST /api/injection-model/suggest is read-only, and "Use this" saves through the existing PUT /api/injection-model. On the CLI, ocx agent injection suggest <work> [--apply] skips settings that already match. The maintainer follow-up sanitizes sizing failures on this path as #6367 did for role auto-assign.

 ## Acceptance
 
+**Re-verification at P (2026-10-01, dev `da13a02727` = #6367).** Pinned `refs/omo/6274` is still `b180fcec0a`. The replay `6c97ca9a4f..b180fcec0a` on `codex/omo-delegation-suggest` hit one conflict in `gui/src/pages/integrations/LazyCodexRoleAutoAssign.tsx`. #6274 moves `TIER_LABEL`/`EFFORT_LABEL` into `sizing-labels.ts`, while #6367 hoisted `alreadySet` to module scope at the same spot. Resolved by taking #6274's move and keeping the module-scope `alreadySet` (gate 3). The rest applied cleanly (12 commits).
+
+Gate 4 compatibility repair `881bb588f4` "fix(carry): keep sizing failure text out of delegation suggest responses": #6274's delegated-work suggest path reuses the sizing completion and still echoed raw error text, the same leak class the #6367 security review found. It now goes through `publicSizingError`, with a regression in `tests/codex-integration/injection-model-suggest-routes.test.ts`. `agent-settings-routes.ts` is 1,943 lines, under the 2,000 ceiling. React Doctor shows 0 diagnostics on the changed GUI files, and the privacy scan passes.
+
+
 - Exact-head required checks pass with the gate 5 coverage assertion; diff equals L3 plus any listed "fix(carry)" compatibility commits.
 - The polite live region stays mounted and announces running and completion text (`gui/tests/subagents-delegation-suggest.test.tsx`).
 - `--apply` skips an already-matching setting and the suggest route is read-only until `PUT /api/injection-model` (`tests/codex-integration/injection-model-suggest-routes.test.ts`).

+### Delegation model suggest
+
+`POST /api/injection-model/suggest` (Subagents page **Suggest**, `ocx agent injection suggest`) applies the
+same sizing to the delegation default. The caller describes the work Codex usually hands off (nonblank, at
+most 1500 characters, the role excerpt limit); `proposeDelegationModel` in
+`src/server/management/codex-role-auto-assign.ts` sends it as one role named `delegated-work` with the same
+parser and the role rubric followed by a short addendum (`DELEGATED_WORK_SIZING_SYSTEM_PROMPT`) that has the
+sizer size the described one-shot work rather than a standing role; the role rubric's own text is unchanged.
+It maps the answer with the same `buildRoleProposals`. Two things differ from roles in the mapping,
+both at the call site: candidates are the `available` list `GET /api/injection-model` offers (one helper
+builds both), with effort ladders cut to the Codex levels `PUT /api/injection-model` accepts, and
+`alwaysProposeEffort` proposes an effort even when none is set, because the delegation effort is a
+picker of its own. The route writes nothing; the page shows tier, effort, rationale and move triggers,
+and **Use this** goes through the page's ordinary `PUT /api/injection-model` save. It is not
+sibling-refused, like the `PUT` it feeds, since both touch only this instance's config.
+
 `injectionModel` and `injectionEffort` are shared selections with two independent consumers.
 `multiAgentGuidanceEnabled` controls only OpenCodex-authored delegation guidance.
 `syncCodexSubagentDefaults` is a separate, default-off opt-in that applies the selected values to

+All three layers of LilMGenius's omo (Codex / LazyCodex) series are on `dev`. Each landed as a maintainer carry PR with `Co-authored-by: LilMGenius <smsmeee@naver.com>`, in dependency order, and each was verified only by hosted CI at its exact head. The owner instructed that no local test suites be run.

+
+## What changed beyond the contributor heads
+
+- `70f696593c` (wp1): the role TOML must parse both before and after a model edit, otherwise the write is refused with `invalid_role_file`. Other write failures answer a fixed `write_failed` message with no path or UID.
+- `30ae36a149` (wp2): auto-assign sizing failures now return only a category or a bare HTTP status (`publicSizingError`). The same commit clears two React Doctor warnings. A later fixture fix (`c721b63cb0`) satisfies the privacy scan.
+- `881bb588f4` (wp3): the same sanitisation for delegation suggest.
+- Union resolutions: wp2 `a0e3ac8d39` (the effort writer) was merged with the wp1 TOML validation. wp3 merged the label move with the module-scope `alreadySet`.
+
+## What did not go to plan
+
+- The first CI runs on wp2 failed twice, on React Doctor and then on the privacy scan. Both failures came from maintainer edits, not contributor code. Running React Doctor and the privacy scan statically before pushing would have caught them.
+- An accidental trial cherry-pick in the main checkout ran against a stale local `dev`. It was aborted with no residue.
+- The wp3 replay and repair happened before A instead of inside B. The FSM refused B→C for having no source delta, so this `_fin` move is wp3's B delta.

Subject: [PATCH 07/61] fix(claude): log a stalled or over-cap passthrough
 stream as a 502 incomplete row (#6354)

* fix(claude): log a stalled or over-cap passthrough stream as a 502 incomplete row

tapAnthropicSseForLog ended a body stall or byte-cap overflow with an
Anthropic error frame but finalized the row as status 200 with only
closeReason body_stall / body_overflow. usage.jsonl persists failure
diagnostics only for rows at status >= 400 or with a non-completed
terminalStatus, so these cut-short turns reached it as plain 200 rows with
no closeReason and no reason: anything reading usage.jsonl counted them as
successes.

The Responses relay logs the same events (a stall-timeout incomplete) as
502 with terminalStatus "incomplete"; httpStatusForRequestLogTerminal maps
only a max_output_tokens incomplete to 200. The tap now does the same: 502,
terminalStatus "incomplete", the existing closeReason, and the proxy's own
message in upstreamError. A mid-stream reset stays 502 / failed, so the two
differ only in terminalStatus. The client stream is unchanged.

This settles the status split raised in the #6235 review.

* fix(claude): treat a stall or overflow after message_stop as a finished turn

Review follow-up. failBody did not check whether the turn's own terminal
(message_stop or an upstream error event) had already gone through, unlike
the read-error branch. An upstream that sent message_stop and then idled
past bodyStallSec, or kept sending past the byte cap, got an error frame
appended after message_stop and, with the 502 row, would have counted as a
failed turn the client had fully received. It now logs 200 / terminal and
closes without a frame.

Tests: A1/A2 compare the full finalize meta; the managed lane gains a
streaming stall case that checks terminalStatus and the tap's reason, and
its fold test pins terminalStatus. The structure doc limits the Responses
parity claim to the stall and describes the byte cap as matching the
non-stream passthrough's 502.

* fix(claude): find passthrough SSE frames delimited by CRLF or CR

CodeRabbit follow-up. The tap's inspection split frames on "\n\n" only, so
a CRLF- or CR-delimited stream never had its frames seen: usage was not
read, and with this PR's terminal check a finished turn that then stalled
or overflowed would be logged as a 502 incomplete with an error frame after
message_stop. The inspection copy is now normalized to LF (forwarded bytes
untouched), holding a trailing CR until the next chunk so a CRLF split
across chunks stays one line ending.

The tail flush the read-error branch already did is now shared with
failBody, so a terminal block still in the buffer (an upstream that went
quiet right after it, or a held CR) counts there too; the blank line is
restored only when the client has not received one.

 ## Native passthrough stream terminals
 
-`tapAnthropicSseForLog` in `src/server/claude-messages.ts` relays the streamed body of both the native passthrough and the managed native Messages lane (`src/server/messages-native.ts`). The response headers are already sent, so a stall, a byte-cap overflow, or an upstream read failure ends the body with an Anthropic `event: error` frame after a blank-line boundary and a clean close: `timeout_error` for an idle stall, `api_error` for the byte cap, and `api_error` when an upstream read fails mid-stream (a socket reset). The mid-stream reset is logged like the Responses relay's read error: status 502, `terminalStatus: "failed"`, `closeReason: "terminal"`, `transportPhase: "mid_stream"`, a synthetic terminal source, the attempt marked `streamAborted`, the redacted reason in `upstreamError`, and the usage seen before the reset. The non-streaming fold in the managed lane closes its row with the tap's meta for a reset, a stall or the byte cap, so its row matches the streaming lane's. The request is not replayed. The logged status is not uniform across these frames: a stall and the byte cap keep status 200 with `closeReason` `body_stall` or `body_overflow`, which classify as `incomplete`, while a reset is a 502 that classifies as `failed`. Some read failures are not upstream failures. When the cancel signal is already aborted, the rejection is a `499` client cancel, because Bun can reject the read before it dispatches the abort listener. The managed lane passes its upstream controller's signal, so shutdown and turn release count as cancels too. When `message_stop` or an upstream `error` event has been seen, including one still in the buffer without its blank-line delimiter, the turn is complete: it logs 200 and closes with no error frame. A terminal found only in that unterminated tail gets its blank line restored, because an SSE parser drops an event that EOF cuts off. A translator budget overflow is a local cap, so it still errors the stream, and the non-streaming fold answers it with 413. `tests/claude-integration/claude-native-passthrough.test.ts` and `tests/claude-integration/messages-native.test.ts` cover both lanes against an upstream that resets after a partial or a complete body, plus both cancel paths.

The non-streaming fold in the managed lane closes its row with the tap's meta for a reset, a stall or the byte cap, so its row matches the streaming lane's. The request is not replayed. Every one of these frames logs status 502. A stall is `terminalStatus: "incomplete"` with `closeReason: "body_stall"`, the status the Responses relay gives a stall-timeout incomplete. The byte cap is `incomplete` with `closeReason: "body_overflow"`, the same 502 the non-stream passthrough answers for it. Both carry the proxy's message in `upstreamError`, and a reset is `terminalStatus: "failed"`. Either way the row keeps its failure diagnostics in usage.jsonl. A stall or overflow after the turn's own terminal (`message_stop` or an upstream `error` event) is a finished turn: it logs 200 and closes without an error frame, as the read-error branch does. The tap finds frames in a copy normalized to LF, because SSE lines may end in CRLF, LF or CR; it holds a trailing CR until the next chunk so a split CRLF stays one line ending, and forwards the original bytes unchanged. Some read failures are not upstream failures. When the cancel signal is already aborted, the rejection is a `499` client cancel, because Bun can reject the read before it dispatches the abort listener. The managed lane passes its upstream controller's signal, so shutdown and turn release count as cancels too. When `message_stop` or an upstream `error` event has been seen, including one still in the buffer without its blank-line delimiter, the turn is complete: it logs 200 and closes with no error frame. A terminal found only in that unterminated tail gets its blank line restored, because an SSE parser drops an event that EOF cuts off.

 A native passthrough answered without a stream records its reason in `upstreamError`, so the row and the failure diagnostics in usage.jsonl name the cause. An upstream error response (status 400 or above) is relayed verbatim; the stored diagnostic is `Provider error <status>: <type>` only for a valid Anthropic error envelope with one of the closed types `invalid_request_error`, `authentication_error`, `permission_error`, `not_found_error`, `rate_limit_error`, `api_error`, `overloaded_error` or `request_too_large`. Upstream messages and arbitrary type strings never enter this diagnostic. Unknown or malformed envelopes, non-JSON bodies and bodies over 64 Ki characters log `Provider error <status>`. Local header timeout, body stall, byte-cap overflow and cancel diagnostics contain fixed text plus validated guard limits. Fetch failures log the fixed reason `anthropic passthrough failed: upstream connection error`; the existing redacted client response is preserved. Classification uses these stored reasons and HTTP status, so a `permission_error` at 403 is `permission_denied` regardless of upstream message wording. `tests/claude-integration/claude-native-passthrough.test.ts` covers these cases and checks that echoed account identifiers and request content are absent from both history sinks.

Subject: [PATCH 08/61] fix(anthropic): clamp budget thinking to the model's
 real output maximum (#6355)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(anthropic): clamp budget thinking to the model's real output maximum

The budget-thinking branch sized `max_tokens` with a flat
REASONING_MAX_TOKENS_CEILING of 32000, so a caller asking for 128000 on Opus 4.6
or Sonnet 4.6 silently got 32000 — a quarter of what those models document. The
adaptive branch directly above already honours an explicit caller limit above
32k; this one overrode it.

The constant dates from Claude 4.x models that really stopped near 32k. Opus 4.6
and Sonnet 4.6 document 128K synchronous output and Haiku 4.5 documents 64K, so
the flat value is no longer a safe ceiling for the families that take this path:
`usesAdaptiveThinking` sends sonnet >= 5, opus >= 4.7 and fable down the adaptive
branch, leaving exactly opus-4-6, sonnet-4-6 and haiku-4-5 here, and all three
exceed 32000.

It now clamps to `configuredMaxOut`, the per-model value already resolved a few
lines above for the omitted-limit default (`modelMaxOutputTokens` falling back to
`defaultMaxOutputTokens`), so this reuses that lookup rather than adding a second
one. REASONING_MAX_TOKENS_CEILING stays the fallback for a target whose ceiling
is unknown, which keeps today's behaviour for an unconfigured provider.

Measured before and after, with the provider carrying the seeded maxima:

  opus-4-6    asked 128000 -> 32000 before, 128000 after
  sonnet-4-6  asked 128000 -> 32000 before, 128000 after
  haiku-4-5   asked 128000 -> 32000 before,  64000 after (its real maximum)
  opus-4-6    asked  10000 -> 24576 both (budget+headroom, unchanged)
  no maxima   asked 128000 -> 32000 both (fallback preserved)

Anthropic's invariant `max_tokens > thinking.budget_tokens` holds in every case
above; the test asserts it alongside the figures.

Follow-up to #6329, where the per-model maxima landed and the reviewer noted this
clamp as still outstanding.

Verification: `bun run typecheck` clean; 73/73 in
tests/adapters/anthropic/anthropic-reasoning.test.ts. The new case fails with
"Expected: 128000, Received: 32000" without the source change. tests/adapters/anthropic
reports the same 654 pass / 30 fail with and without it — those are pre-existing
account-pause/pacing failures on dev, unrelated to max_tokens.

* fix(anthropic): let the stated ceiling only raise, never lower, the thinking clamp

Addresses CodeRabbit's finding on #6355: the first revision treated
`configuredMaxOut` as a capability ceiling, but that value is two different
things depending on the provider.

On the canonical Anthropic entries it is a documented Messages API maximum. On any
other provider it is a plain fallback budget for requests that omit
`max_output_tokens`. Reading the second as the first meant an operator's
deliberately cheap `defaultMaxOutputTokens: 8192` was interpreted as "this model
cannot emit more", so an explicit 128000 request was clamped to 8192 with the
thinking budget squeezed to 4096 — below the 32000/16384 this path produced before
the change. Reproduced before fixing:

  defaultMaxOutputTokens 8192, explicit 128000, high effort
    before this commit: max_tokens 8192,  budget_tokens 4096
    base (pre-PR):      max_tokens 32000, budget_tokens 16384

The clamp now takes the LARGER of the configured value and
REASONING_MAX_TOKENS_CEILING, so the historical ceiling acts as a floor: a stated
maximum can lift it where the vendor documents more, and a low fallback budget can
never drag it below what the flat constant already allowed.

  seeded maxima   opus-4-6  explicit 128000 -> 128000 (its documented maximum)
  seeded maxima   haiku-4-5 explicit 128000 ->  64000 (its documented maximum)
  cheap 8192      opus-4-6  explicit 128000 ->  32000 (floor held, budget 16384)
  no maxima       opus-4-6  explicit 128000 ->  32000 (unchanged)

The fallback budget still decides an omitted request, which is what it is for, and
that is asserted too so the two roles stay distinguished.

Verification: `bun run typecheck` clean; 74/74 in anthropic-reasoning.test.ts, the
new case covering the low-budget regression with the explicit assertion that
budget_tokens stays 16384. tests/adapters/anthropic unchanged at the same
pre-existing 30 failures.

Subject: [PATCH 09/61] fix(anthropic): enforce model routes for vision and
 search helpers (#6371)

Resolve Anthropic vision and web-search helper credentials through the same per-model account route as primary requests and carry the admitted config snapshot through sidecar planning and execution. An empty strict route is refused locally, so a helper can no longer use an account the model route excludes.

Use stored account IDs from `ocx account list anthropic --json`. Rules only affect the enabled pool and never claim that an account is entitled to a model. Request logs identify a matched rule as `route:#<n>` (1-based list position), without its operator name.

+Vision and web-search helpers match their own model independently and can fail locally when their
+strict route has no eligible account. See [Anthropic helper account routing](/reference/configuration/providers/#anthropicaccountpool-experimental).

Without fallback, an empty route returns a local 401, or 429 with route-scoped `Retry-After` if all its declared accounts are cooling. With `fallback: true`, an all-cooling ordinary pool returns 429 with its earliest usable cooldown, even if a saved route account was removed; the client response never names the route; the proxy log uses `route:#<n>` for the rule’s 1-based position. `fallback: true` widens only when no routed account is eligible; fill-first then uses ordinary pool order. No matching rule retains normal selection; disabling the pool makes saved routes inactive. Invalid rules fail validated writes and prevent routed dispatch until corrected. `null` clears routes through the settings API. |
 
+Anthropic OAuth vision and web-search helpers match these routes using each helper's own model,
+independently of the main request model. Each helper authenticates with its routed account, which
+can differ from the globally active account. If a strict helper route has no eligible account, the
+helper fails locally before any provider request; it does not silently use an account outside the
+route. When the main request works but image description or web search fails, check the helper's
+configured model and the accounts eligible for that model's route.
+
 When enabled, 429 records a cooldown and may rotate within the request. The cooldown length comes
 from a usable `Retry-After`, otherwise from the latest valid reset time among rate-limit windows

+Anthropic account pause, model routes, and quota labels follow the [Anthropic account-pool contract](providers/anthropic-account-pool.md). Devin Messages follows the [per-turn output ordering contract](clients/claude-desktop.md#devin-messages-output-ordering), preserving late signatures before text/tools without changing Responses or Chat ordering.
 
 Per-account usage thresholds follow the [Anthropic account thresholds contract](providers/anthropic-account-thresholds.md).
 An Anthropic 429 or classified pre-output account 403 records the served account's cooldown even when the request has used its allowed retry sends. That final account remains excluded on the next request; combo target cooling for 429 is skipped only after the matching account cooldown is present.
 
-GitHub Copilot `modelContextTiers` is selected per upstream model. The Chat and Responses
-adapters set `contextTier` only when the canonical routed provider is `github-copilot`
+The Anthropic helper sends share the same routing authority: `getAnthropicSidecarAccessToken` resolves the vision-describe and web-search sidecars' helper model through the same first-match route decision, so a routed send authenticates as the route's own account rather than whatever pool account happens to be active. A strict route with no eligible account fails the helper locally instead of silently falling back to the active outsider, matching the primary-traffic contract; callers without a pool config keep the plain stored-credential path.
+
+GitHub Copilot `modelContextTiers` is selected per upstream model. The Chat and Responses adapters set `contextTier` only when the canonical routed provider is `github-copilot`
 and a tier is configured. Otherwise passthrough retains caller-supplied values. The server carries provider identity
 through initial builds, retries, continuations, and sidecar builds.

Subject: [PATCH 10/61] fix(gemini): bound type-array schema normalization and
 preserve pointers (#6369)

Gemini/Devin tool-schema normalization no longer copies surrounding constraints into every type-array branch: constraints stay once on the original node, type alternatives become type-only branches, an existing anyOf keeps its position with the type constraint appended to allOf, and a null-only result yields a single null branch instead of an empty anyOf. Output now grows linearly.

Reviewed at 7b2272832a506a64edd0c89ce14cd975341f4358; hosted Cross-platform CI 36842797911 green.

Shared constraints remain on the surrounding node, so nested schemas have one wire representation while outer enum/const, boolean constraints (including `not`, `oneOf`, and `allOf`) on null, and existing null-branch restrictions retain their conjunctive meaning. A null-only type keeps its null constraint even when an outer enum/const excludes null, preserving an unsatisfiable schema without producing an empty anyOf. Schema resource identifiers, anchors, definition maps, and existing anyOf branches remain on their original node.

For every `xiaomi/mimo-` model, text, native calls, reasoning, and terminal decisions share one byte-bounded queue with linear queue visits. Markup is deduplicated against matching native calls; text-only restoration requires one contiguous bare text block, a clean finish, a declared tool, and arguments validated against supported schema constraints. A parameter-free (freeform) block may omit `</function>` but must end with `</tool_call>`; parameter blocks keep the canonical close. Markup appended after prose, including a marker in a later delta of the same text block, is held as a tail that can never mint a call: possible trailing marker prefixes stay in the same byte-accounted probe across deltas and release as text on a mismatch, boundary or end; a same-content native call strips a completed envelope as an echo, and anything else releases as presentation text so quoted examples stay inert. A tail waits only while a native input it could echo is open, counting the first later input of its own tool, so it is released as soon as those close without a match. Native, reasoning, and other intervening events interrupt a still-probing block but leave a held block held in arrival order, and the queued byte bound still flushes an unresolved envelope as text. An envelope the strict parser rejects but that opens with `<tool_call>`, closes with `</tool_call>`, and names a declared function is dropped when a native call for that same function arrives and on a clean finish; markup that parses but fits no supported schema is still released as text. Regex patterns, other unsupported constraints, and abnormal finishes fail closed. `tests/providers/command-code-tool-text-prose-split.test.ts` covers the prose boundary, the interleaved-event hold, and both drop paths. |

Subject: [PATCH 11/61] fix(antigravity): enforce one sibling rotation across
 authentication failures (#6372)

Apply the existing one-sibling Antigravity authentication rotation guard to the terminal-refresh branch, so a request that already rotated after a structured VALIDATION_REQUIRED 403 cannot rotate again when the sibling's refresh fails terminally. Regression: A 403 -> B terminal refresh failure -> C never sent.

Subject: [PATCH 12/61] fix(kiro): retry rebuilt requests at the rebuilt
 destination (#6374)

A Kiro connection-reset retry now uses the rebuilt request URL for the physical retry and for send-budget admission, and derives legacy gateway fallback from the rebuilt region. A rebuilt destination is recorded separately from the one permitted alternate-target transition, so the new region keeps its normal gateway fallback while the total send cap still applies.

+A reset-triggered rebuild may retarget the request to another region's canonical host mid-flight; that admission is marked `rebasedTarget` and does not consume or require an unused transition/alternate-target allowance (the total-send and replay-safety checks still apply), and the alternate-host fallback resolves the legacy gateway from the current request URL so rebuilt credentials stay with their own region.

Subject: [PATCH 13/61] fix(kiro): release leases granted across request
 cancellation (#6377)

Keep request cancellation visible for the whole Kiro request, pass the abort signal into lease acquisition, and release any lease granted across the abort race before it can be installed or used. src/server/responses/core.ts reaches exactly its 210-line file-size cap.

 Catalog HTTP acquisition follows the [proxy-routing contract](catalog.md#remote-catalog-http-proxy-routing). CLI model lists expose shared catalog estimates as `price`; `models price` retains the saved override in `cost` and adds `effectiveCost`. Explicit zero overrides win; unknown prices remain null, and automatic defaults are never persisted to `modelCosts`. Covered by `tests/cli/cli-models.test.ts` and `tests/cli/cli-models-price.test.ts`. Ordinary model discovery, startup sync, and explicit sync apply the [new-arrival catalog contract](catalog.md#shared-catalog) before publishing rows. The scoped persisted decision also updates the live config merge baseline, so subsequent visibility writes preserve manual re-enablement. A file-loaded inventory that already differs from disk can publish HTTP rows through a detached policy projection without adding unsaved live disables; retained catalog writes still refuse stale inventory, and its load provenance follows the [config contract](config.md).

Subject: [PATCH 14/61] fix(xai): authorize the Fast wire model across API
 endpoints (#6373)

Grok Fast mode can serialize grok-4.7-build-fast while the logical route names grok-4.7. The effective wire model is now checked against the caller allowlist across Responses, compact, Chat Completions and Messages; an explicit provider fastWire destination is authorized by its logical id. Docs (en + 7 locales) distinguish the built-in build-fast lane from an explicit fastWire destination.

+Sans configuration explicite de `fastWire` pour le fournisseur, une clé API opencodex limitée par `allowedModels` doit autoriser `xai/grok-4.7-build-fast` (ou son identifiant sans préfixe) pour les requêtes Fast via OAuth. Autoriser uniquement `xai/grok-4.7` ne donne pas accès à cette variante Fast. Une clé limitée au modèle Fast peut utiliser cette variante ; les requêtes ordinaires ou Fast désactivé exigent toujours `xai/grok-4.7`. Si un `fastWire` explicite est configuré, autorisez le modèle réellement envoyé : par exemple, un wire de type `service-tier` conserve `xai/grok-4.7` et exige la permission pour ce modèle.

 OpenRouter는 하나의 모델을 여러 추론 공급자로 제공할 수 있습니다. `openRouterRouting`은 요청을 선호하는 공급자에 유지하고, `modelOpenRouterRouting`은 정확한 모델 id에 대해 이를 대체합니다. 캐시 지원, 유지 시간, 히트율, 가격이 추론 공급자마다 다르기 때문에 프롬프트 캐시 결속에 유용합니다.

Subject: [PATCH 15/61] fix(config): require owner-only no-follow registry
 publication (#6375)

Owner-registry publication could follow a symlink planted at the final entry, and a permissive registry directory could expose the publication surface. Reject a symlinked or non-directory registry path, require the owner-only directory hardening helper (also on Windows), and publish entries with the no-follow atomic writer.

Subject: [PATCH 16/61] fix(codex): reject unpaired surrogates in discovered
 model metadata (#6368)

Native-model discovery accepted JSON-escaped lone UTF-16 surrogates in model descriptions or nested metadata, which could be persisted and published into a catalog a strict JSON consumer cannot read. After the existing bounded JSON round trip, reject a discovered row containing an unpaired surrogate in any string value, object key or array element. Valid surrogate pairs remain accepted.

 Configured natives widen the bare list without a release: eligible bare `gpt-*` ids under `providers.openai.models` on the canonical Codex forward provider join the shared registry in place (`src/codex/catalog/native-models.ts`). Each borrows the pinned `gpt-6.1-sol` row under its generated name, takes `NATIVE_GPT6_CONTEXT` (272,000 / 872,000), and is ungated. Built-in, retired and reserve ids never register. `src/config/derived-registries.ts` filters the config and refreshes registration on load, persist and reconcile; removing a configured id unregisters it unless it is also discovered. Configured natives have no entitlement routing preference or main-drain sentinel and cannot be combo `nativeAlias` targets because schema validation precedes registration. Covered by `tests/codex-integration/configured-native-models.test.ts`.
 
-Authenticated discovery also widens the set: after a successful nonempty roster fetch, `src/codex/model-entitlements.ts` passes full eligible rows to `src/codex/catalog/discovered-natives.ts`. Rows require a visible, API-supported bare `gpt-*` slug, display name and sane reasoning-level array; built-in, retired, reserve, malformed and oversized rows are rejected. Existing discoveries and configured natives remain eligible for refresh, so an already-supported slug does not freeze its metadata or keep borrowing a template.
+Authenticated discovery also widens the set: after a successful nonempty roster fetch, `src/codex/model-entitlements.ts` passes full eligible rows to `src/codex/catalog/discovered-natives.ts`. Rows require a visible, API-supported bare `gpt-*` slug, display name and sane reasoning-level array; built-in, retired, reserve, malformed, oversized and non-scalar Unicode rows are rejected. Existing discoveries and configured natives remain eligible for refresh, so an already-supported slug does not freeze its metadata or keep borrowing a template.
 
 The store keeps version-1 `discovered-native-models.json` under the resolved OpenCodex home using the private atomic writer (0600 on POSIX). It merges by slug with first/last observation times and client version, expires entries unseen for 14 days, and bounds rows to 32, each to 256 KiB (a live row carries its instructions twice; GPT-6.1 Sol's was 87 KB), plus a file-size bound. Each record re-reads the file and merges onto it, so another process's discovery survives (the replace is atomic, not locked), and an unchanged row renews its last-seen time on disk at most hourly so request-time roster fetches rarely write. The discovery ETag is sent only within 24 hours of the full fetch that earned it, because a 304 cannot renew retention. Missing/corrupt files read as empty; persistence failures never fail entitlement. Config activation loads the file through derived registries; observations register immediately. A process-local monotonic generation changes for metadata or membership changes, independently of timestamp refreshes.

Subject: [PATCH 17/61] fix(chat): recognize Eliza qwen3-8-27b checkpoint ids
 in the leading-system template (#6385)

The openai-chat leading-system template selector matched only Qwen3.8-27B (optionally Qwen/-prefixed). Internal Eliza serves the same pinned template under dashed checkpoint ids (qwen3-8-27b, -fp8, -lora), which failed upstream with "System message must be at the beginning". Match those ids too.

Reviewed at fc6156278e; hosted Cross-platform CI 36851335539 green.

Subject: [PATCH 18/61] fix(command-code): preserve canonical path case in
 project confinement (#6323)

fix(command-code): preserve canonical path case in project confinement (#6323)

Project-context loading lowercased Windows paths before checking containment, so a
case-sensitive sibling directory such as PROJECT could pass as the project directory.
Containment now uses an exact, case-preserving canonical prefix check with component
boundaries, including at drive and UNC roots. The opened file must also resolve back to
the byte-identical canonical path before its contents are published.

fix(gui): keep native login confirmation readable and contained (#6388)

The native-login confirmation inherited the shared warning notice's horizontal flex layout,
so German copy and a long home path collapsed into narrow columns and the confirm button
overflowed the panel. The confirmation now renders as a block, and its action row and
button text wrap within the panel. A rendered CSS-cascade regression test covers the
real view against the shared stylesheet.

Addresses the layout part of #6387.

Subject: [PATCH 20/61] fix(config): surface why macOS proxy "auto" refuses
 (exception shapes, SOCKS-only) (#6205)

macOS `proxy: "auto"` now explains why discovery was refused: SOCKS-only and disabled transports, the specific toggle (ExcludeSimpleHostnames, PAC, WPAD), and counts of untranslatable exception entries by shape, without logging the entries themselves. With no HTTP(S) proxy, PAC/WPAD are reported before disabled or SOCKS-only.

 role-route write-failure test (#6399)

test(codex): match the canonical role path in the role-route write-failure test (#6399)

getCodexHome() canonicalizes CODEX_HOME, so the role route reads the real path. On macOS
the temp root is under /var, a symlink to /private/var, and on Windows runners tmpdir() is
the 8.3 short path. The readFileSync spy matched the spelled path, never fired, and the
write succeeded, so the test failed on both platforms and passed only on Linux. The spy
now matches the canonical role path, the test asserts that the spy denied a read, and it
checks that neither the spelled nor the canonical root leaks into the response.

Subject: [PATCH 22/61] fix(claude): relay native Anthropic rate-limit headers
 (#6356)

Relay upstream anthropic-ratelimit-* response headers on native Anthropic passthrough (SSE, JSON, error and count_tokens responses) so Claude Code statusLine rate_limits are populated. Only that header family is forwarded; cookies, auth and request-id headers are not.

Closes #6297

 ## Claude OAuth account pool (experimental)
 
+Native Anthropic subscription passthrough retains the upstream `anthropic-ratelimit-*`
+response headers on streaming, JSON and upstream-error responses, so compatible Claude Code
+statusLine consumers can read the provider's quota observations. Missing observations are
+not filled with invented values. This relay does not change account selection or retry behavior.
+
 You can log in multiple Claude accounts via the Providers dashboard (`ocx login anthropic` /
 add-account). By default every request uses the **active** account only.

 ## Native passthrough stream terminals
 
+Native passthrough retains upstream `anthropic-ratelimit-*` response headers for Claude Code quota/statusLine consumers on SSE, JSON and upstream errors. `src/server/anthropic-rate-limit-headers.ts` selects only that family instead of copying all upstream headers, so cookies and unrelated metadata are not relayed. Missing rate-limit headers are not fabricated; body, status, content type and existing non-stream `Retry-After` behavior stay unchanged. `tests/claude-integration/claude-native-rate-limit-headers.test.ts` exercises the production ingress against a synthetic upstream for all four response shapes (SSE, JSON, upstream error and count_tokens).
+
 `tapAnthropicSseForLog` in `src/server/claude-messages.ts` relays the streamed body of both the native passthrough and the managed native Messages lane (`src/server/messages-native.ts`). The response headers are already sent, so a stall, a byte-cap overflow, or an upstream read failure ends the body with an Anthropic `event: error` frame after a blank-line boundary and a clean close: `timeout_error` for an idle stall, `api_error` for the byte cap, and `api_error` when an upstream read fails mid-stream (a socket reset). The mid-stream reset is logged like the Responses relay's read error: status 502, `terminalStatus: "failed"`, `closeReason: "terminal"`, `transportPhase: "mid_stream"`, a synthetic terminal source, the attempt marked `streamAborted`, the redacted reason in `upstreamError`, and the usage seen before the reset. The non-streaming fold in the managed lane closes its row with the tap's meta for a reset, a stall or the byte cap, so its row matches the streaming lane's. The request is not replayed. Every one of these frames logs status 502. A stall is `terminalStatus: "incomplete"` with `closeReason: "body_stall"`, the status the Responses relay gives a stall-timeout incomplete. The byte cap is `incomplete` with `closeReason: "body_overflow"`, the same 502 the non-stream passthrough answers for it. Both carry the proxy's message in `upstreamError`, and a reset is `terminalStatus: "failed"`. Either way the row keeps its failure diagnostics in usage.jsonl. A stall or overflow after the turn's own terminal (`message_stop` or an upstream `error` event) is a finished turn: it logs 200 and closes without an error frame, as the read-error branch does. The tap finds frames in a copy normalized to LF, because SSE lines may end in CRLF, LF or CR; it holds a trailing CR until the next chunk so a split CRLF stays one line ending, and forwards the original bytes unchanged. Some read failures are not upstream failures. When the cancel signal is already aborted, the rejection is a `499` client cancel, because Bun can reject the read before it dispatches the abort listener. The managed lane passes its upstream controller's signal, so shutdown and turn release count as cancels too. When `message_stop` or an upstream `error` event has been seen, including one still in the buffer without its blank-line delimiter, the turn is complete: it logs 200 and closes with no error frame. A terminal found only in that unterminated tail gets its blank line restored, because an SSE parser drops an event that EOF cuts off. A translator budget overflow is a local cap, so it still errors the stream, and the non-streaming fold answers it with 413. `tests/claude-integration/claude-native-passthrough.test.ts` and `tests/claude-integration/messages-native.test.ts` cover both lanes against an upstream that resets after a partial or a complete body, plus both cancel paths.
 
 A native passthrough answered without a stream records its reason in `upstreamError`, so the row and the failure diagnostics in usage.jsonl name the cause. An upstream error response (status 400 or above) is relayed verbatim; the stored diagnostic is `Provider error <status>: <type>` only for a valid Anthropic error envelope with one of the closed types `invalid_request_error`, `authentication_error`, `permission_error`, `not_found_error`, `rate_limit_error`, `api_error`, `overloaded_error` or `request_too_large`. Upstream messages and arbitrary type strings never enter this diagnostic. Unknown or malformed envelopes, non-JSON bodies and bodies over 64 Ki characters log `Provider error <status>`. Local header timeout, body stall, byte-cap overflow and cancel diagnostics contain fixed text plus validated guard limits. Fetch failures log the fixed reason `anthropic passthrough failed: upstream connection error`; the existing redacted client response is preserved. Classification uses these stored reasons and HTTP status, so a `permission_error` at 403 is `permission_denied` regardless of upstream message wording. `tests/claude-integration/claude-native-passthrough.test.ts` covers these cases and checks that echoed account identifiers and request content are absent from both history sinks.

Subject: [PATCH 23/61] fix(responses): record first-output timing for
 tool-only streams (carry #6259) (#6392)

A Responses turn that produced only a tool call recorded output tokens with no first-output time. Count non-empty response.function_call_arguments.delta and response.custom_tool_call_input.delta in native Responses SSE, and non-empty tool_call_delta arguments in the adapter bridge, as first output. Empty deltas, tool scaffolding, lifecycle and control frames still do not start the timer, and reporting stays once-only.

Carried from #6259.

+Responses first-output timing includes streamed function arguments and custom-tool input, as well
+as text and reasoning. A tool-only turn can therefore have a first-output time even without prose.
+Empty deltas and tool-start notifications do not start this timer. It measures the proxy's first
+observed output, not the start of hidden model reasoning or exact model decoding throughput.

Subject: [PATCH 24/61] fix(codex): verify service manager identity before
 census delegation (carry #6379) (#6397)

A managed service could select a recorded runtime without proving that the live service-manager definition belonged to the same OpenCodex and Codex homes. Bind census delegation to that definition and refuse missing, ambiguous, or mismatched identity evidence before probing or launching a candidate. Decode the quoted home assignments emitted by the systemd writer. For the WinSW backend, also require trusted sc.exe qc to report the definition's own executable as the registered binary.

Carried from #6379.

 domain to query. The probe returns what it saw and does not decide ownership; callers such as
 `src/integrations/native/ownership-preflight.ts` compare the homes. Every command it runs is
 read-only and time-bounded, so it is safe while the proxy runs under that same manager.
+Systemd home parsing in `src/service/systemd-env.ts` decodes the generated quoted escapes and
+doubled percent signs, with legacy simple bare assignments retained. Unknown escapes, unresolved
+specifiers, malformed quotes, resets and duplicate home assignments make the whole definition
+unknown in both online and offline probes; they never become omitted homes for ownership comparison.
+Non-comment physical line continuations also make the definition unknown before directive matching;
+the generated format uses single physical lines, while systemd otherwise folds continuations first.
+Directive names are matched literally like systemd's parser: only an exact `Environment` is
+decoded, while env-bearing siblings (`EnvironmentFile=`, `PassEnvironment=`, `UnsetEnvironment=`),
+escaped or malformed directive names, and `.include` all invalidate the definition instead of
+being skipped, because a directive the parser ignored could still change the environment the
+unit applies.
 On Windows, the generated-wrapper check accepts package installs that invoke the source CLI.
 A standalone wrapper that invokes `start` directly must carry the generated protocol and runtime
 markers, one quoted `OCX_BUN` assignment, and no `OCX_CLI` assignment in either quoting form.

Subject: [PATCH 25/61] feat(zed): experimental Zed Hosted AI provider, use at
 your own risk (carry #5912) (#6362)

Carries #5912 by @andrew05060414. It adds an experimental, use-at-your-own-risk Zed Hosted AI provider:

- native-app RSA callback login
- an account-scoped short-lived LLM token
- a bounded live model roster
- Anthropic, Google, Responses and Chat requests wrapped in Zed's /completions envelope

The provider is opt-in behind the elevated-risk login warning.

Maintainer follow-ups:
- requests sign with Zed's user_id (OAuthAccessSnapshot.providerUserId) rather than the store slot id
- the stream fails closed on malformed, oversized, partial or unterminated frames
- catalog calls get an 8 s deadline
- the manual-paste login stops once login settles
- upstream failure text is scrubbed of the account token and user id

+# 010 — Finish the Zed Hosted provider carry (#5912)
+
+Unit: carry andrew05060414's experimental Zed Hosted AI provider (#5912) onto `dev` as a
+maintainer PR. Maintainer decision (2026-10-01): adopt as use-at-your-own-risk (UAYOR).
+
+## State at entry
+
+Branch `codex/zed-hosted-ai-carry`, 5 commits ahead of `origin/dev`, 0 behind, already pushed
+at `03e9dce881`. Carried: native RSA callback login (`src/oauth/zed.ts`), account-scoped
+short-lived LLM token exchange with expiry refresh (`src/providers/zed.ts`), live roster, the
+`/completions` envelope adapter for Anthropic / Google / OpenAI Responses / xAI Chat
+(`src/adapters/zed.ts`), UAYOR wording in the dashboard ToS-risk set (`gui/src/oauth-tos-risk.ts`)
+and in `docs-site` guides/providers, reference/adapters, reference/configuration/providers.
+
+## Remaining diff (this cycle)
+
+1. `src/providers/zed.ts` — `scrubZedCredentials()` removes the account access token and the
+   user id from upstream error text before it becomes an `Error` message, on the two calls that
+   send the account credential (account lookup, LLM token exchange). `responseJson` takes the
+   credentials. The `/completions` path carries only the short-lived LLM token and keeps the
+   generic `redactSecretString`.
+2. `tests/providers/zed-hosted-provider.test.ts` — regression: a 401 body echoing both values
+   yields a message that names the step and contains neither value. Trailing newline restored.
+3. Commit with `Co-authored-by` for andrew05060414; push (no force).
+4. Open the maintainer PR to `dev` with every template section, `Co-authored-by`, the UAYOR
+   framing, an explicit security-review request (OAuth / credential path per MAINTAINERS.md),
+   and real-account UAT stated as not verified.
+
+## Verification
+
+Local test and typecheck runs are banned for this lane (maintainer instruction). Evidence is
+the exact-head hosted CI of the PR; queued, skipped, or cancelled checks are not passes.
+Failures are read with `gh run view --log-failed`, fixed, and pushed again.
+
+## Closeout
+
+When exact-head CI is green, close #5912 with a link to the new PR and thanks. Do not merge.
+
+## Reflection
+
+The remaining risk is reviewer-side, not mechanical: Zed's service terms. That is why the PR
+asks for security review and states UAYOR instead of claiming support. No change to core
+request paths (`src/router.ts`, `src/server/lifecycle.ts`, `src/server/responses/core.ts`).
+
+## Audit round 1 (FAIL) — folded into this plan
+
+Reviewer (gpt-6.1-sol, read-only) found three P1 blockers; all are accepted.
+
+5. **Rejection boundaries.** `fetchZedAuthenticatedUser` and `fetchZedLlmToken` can reject from
+   `fetchFn` or from the body read inside `responseJson` with a message that echoes the account
+   credential, bypassing `scrubZedCredentials`. Add `scrubZedRejection(error, credentials)`, which
+   decides only on content: if the error's message (or `String(error)` for a non-Error) contains
+   neither the account token nor the user id, rethrow the original by identity, so a clean abort
+   keeps its identity. If it contains either, throw a replacement that never carries the value: a
+   `DOMException` with the same `name` and the scrubbed message when the original is a
+   `DOMException` (so `AbortError`/`TimeoutError` cancellation semantics survive), otherwise an
+   `Error` with the scrubbed message and the same `name`; numeric `status` is copied over and
+   the original is dropped as `cause` (its message would leak). The `await fetchFn(...)` and
+   `await responseJson(...)` calls of both functions sit inside the `try` whose `catch` applies
+   it, and so does the `/completions` fetch inside `zedLlmFetch`. Regression cases: fetch
+   rejection echoing both values; body-read rejection (a stream that errors mid-read) echoing them;
+   numeric `status` preserved; a credential-bearing `AbortError` comes back as an `AbortError`
+   without the values; a clean `AbortError` is rethrown by identity.
+6. **File-size ratchet.** `src/server/management/provider-routes.ts` is 1998 lines on `dev` with no
+   baseline cap; the carried 22-line Zed probe takes it to 2020, past the 2000 NEW_OVERSIZED
+   threshold. Move the probe into `src/server/management/zed-provider-probe.ts`
+   (`probeZedProvider(prov, apiKey, accountId)`) and call it with a single dynamic-import line, so
+   the file ends at 1999 lines and Zed code stays off the module graph until a Zed probe runs.
+7. **Preset counts.** The registry grows from 100 to 101 presets (Zed is OAuth; key-based stays 83).
+   Update the anchored sentence in all eight provider guides (total 101, OAuth 14), all eight
+   quickstarts (101), and `structure/ops/docs-and-release.md` (101 total, 14 OAuth), as checked by
+   `tests/ci-workflows/docs-provider-preset-counts.test.ts`. Union risk: another open lane (Mirasim)
+   also adds a preset; whichever lands second must recount, and the PR says so.

+Zed does not provide or endorse this bridge. It reuses your Zed account's hosted-model
+entitlement outside the Zed editor, which may be outside Zed's terms of service. Zed may rate
+limit, restrict, or suspend the account. Review Zed's current terms before you sign in; the
+provider stays off until you add it and run `ocx login zed` yourself, and the dashboard asks
+you to acknowledge this risk before it starts the login.
+:::
+
+Run `ocx login zed` and complete Zed's native-app sign-in in the browser. OpenCodex starts a
+loopback callback, gives Zed an RSA public key, and keeps the matching private key local while
+the callback returns the account identity and encrypted access token. The stored account id and
+token are paired on every request; OpenCodex exchanges that credential for Zed's short-lived LLM
+token before calling `https://cloud.zed.dev/completions`.
+
+Zed's live model roster is account-scoped display metadata. The selected model id is forwarded as
+provided, and the bridge infers the hosted backend family from the live row or the model name;
+model discovery is not an allowlist. The Zed access token has no refresh endpoint, so when Zed
+revokes it, run `ocx login zed` again.

+    }
+  }
+}
+```
+
+The bridge obtains a short-lived hosted-inference token and sends `POST /completions`. The live
+`/models` roster is used for account-specific picker metadata only: arbitrary model ids remain
+forwardable, with the backend family inferred from the live provider field or model name.

Both are refused with a 400 at the single guard every registered adapter passes through, rather than left to each adapter, because an adapter that never learned about the carrier rebuilds without it and answers normally. `allowed_callers` reaches the `anthropic` wire; document bytes reach `anthropic`, `openai-chat` and `google`; the `openai-responses` wire is exempt from the whole guard because it forwards the original body.

 | `src/adapters/devin.ts`, `src/adapters/devin/cloud-direct/` | Devin runTurn transport over Cognition Connect-RPC. Assistant reasoning replays as ChatMessagePrompt #11 thinking, #12 signature and #18 signature type (`src/adapters/devin/reasoning-signature.ts`): the #10/#21 pair arrives after the visible answer and becomes its own signature-only reasoning item, so a single unsigned thinking block plus exactly one signature-only block is replayed as one signed prompt, and a signature-only turn (GPT, Gemini) is replayed rather than dropped. An Anthropic signature is replayed, but because the streamed thinking is a summary the signature may not cover, a turn Cognition refuses with `invalid_argument` before any visible output (reasoning alone does not count) is retried once with Anthropic signatures withheld and the thinking text kept. `GetChatMessage` uses the Responses provider executor and shared physical-send budget; catalog, JWT, and `src/web-search/devin-executor.ts` native search support RPCs remain outside inference-send accounting. Provider-stated pre-output 429 reset delays are surfaced immediately by default, releasing shared active-turn capacity. A positive `OPENCODEX_DEVIN_STATED_RESET_WAIT_MS` explicitly enables bounded waiting and up to two replays on standalone turns, which hold that capacity until completion or cancellation. Combo children bypass that wait and surface a pre-output 429 so the next target can run. During an opted-in standalone wait, safe heartbeats commit the response preflight and keep the stream's stall watchdog fed. Invalid values fail closed to the immediate-refusal behavior. A recorded tenant host is used only for the stored account whose credential owns the transmitted key, searched in the configured provider id and then its deprecated alias; a configured, forwarded, or unmatched key uses the configured base URL or the US default. Native search previews the current route by effective adapter without mutating combo selection state, pins one admitted active-account snapshot for the request, and calls `GetWebSearchResults`, so it starts no CLI or second model. The wire model UID comes from the catalog's family metadata (`ClientModelConfig` #23/#30/#31): a family id with no effort anchors on the family's default member and selects the nearest enabled rung, rounding up first; an effort moves only the effort axis, to the lowest rung at or above it (else the highest below) while Fast Mode, 1M Context and the other axes stay at the anchor's values unless the caller asked for `fast` or a `1m` value; not lowering a requested effort outranks keeping those axes (an unranked member counts as lower), a disabled row the caller named is kept when the request still selects it so the preflight names that refusal, and resolution never leaves the family. Rows without family metadata fall back to suffix resolution, whose variant scan matches the collapsed base rather than a string prefix. With no caller or configured output cap, the selected row's catalog `maxOutputTokens` fills CompletionConfiguration #2; #3 is `max_newlines` and is sent at a fixed value, never a context window. The leading system text is sent as `GetChatMessage` #2, a failed tool result sets ChatMessagePrompt #9 and keeps an in-band `ERROR:` marker, and Gemini uids have JSON-Schema type arrays expressed as type-only `anyOf` branches in tool parameters. Shared constraints remain on the surrounding node, so nested schemas have one wire representation while outer enum/const, boolean constraints (including `not`, `oneOf`, and `allOf`) on null, and existing null-branch restrictions retain their conjunctive meaning. A null-only type keeps its null constraint even when an outer enum/const excludes null, preserving an unsatisfiable schema without producing an empty anyOf. Schema resource identifiers, anchors, definition maps, and existing anyOf branches remain on their original node. The type constraint is appended to existing allOf entries without shifting their indices, so JSON Pointer targets and reference scopes remain unchanged. A pre-output `invalid_argument` on a history whose word-piece estimate, using the sanitized and truncated tool descriptions actually sent on the wire, reaches 95% of the selected UID's catalog input window, capped by configured provider and model limits (512 KiB of text only when no window is known) is surfaced as `context_length_exceeded` so Codex compacts; a small request with the same code stays a plain 400. Known limit: a malformed schema on a history already at or above that 95% threshold is also reported as overflow because the upstream returns the same `invalid_argument`. The `COGNITION_BLOCKLIST_REWRITES` sanitizer rewrites exact phrases Cognition refuses with `permission_denied`; it runs only on instruction surfaces — tool descriptions and the #2 system prompt — while message text, replayed thinking (#11), and tool-call arguments stay byte-exact, because a rewrite there would silently change literal content such as patches or quoted file bytes; a trigger inside a data field surfaces as the upstream `permission_denied` instead (the Codex `<permissions instructions>` escalation boilerplate is the recorded #2 case). |

Subject: [PATCH 26/61] fix(kiro): rebind continuation ownership after refusal
 failover (#6376)

Kiro refusal failover replaced the OAuth account snapshot without rebinding the request continuation owner. Bind the continuation and reasoning replay scope to the replacement account after it is selected and before the request is rebuilt or sent; foreign continuation state is removed and response state belongs to the admitted account. The generic OAuth 429 rotation arm had the same gap and now rebinds the same way. Regressions cover buffered and streamed refusals and the source order of both arms.

Reviewed at 02f32ae1f9; hosted Cross-platform CI 36865640257 green.

Subject: [PATCH 27/61] fix(combos): a pool-held 429 must not park the combo
 target past the pool (#6383)

When every Anthropic OAuth account is cooled, the pool refuses locally with a 429 whose Retry-After restates the earliest per-account cooldown. The combo target now cools for the local fallback on that pool-local refusal instead of the restated wait (up to the 24h server-delay cap), so a resumed or newly added account is not ignored. Genuine upstream 429s (API-key providers, identified pool accounts) keep their full Retry-After.

Follow-up to #6255.

The Anthropic OAuth pool's own all-accounts-cooled 429 is the one unattributed exception: `isAnthropicPoolLocalRefusal` in `core-combo.ts` requires the `anthropic` provider with `authMode: "oauth"`, status 429, no identified failed account, no eligible pool account and a live pool retry-after. The target then still cools, but for the local fallback instead of the restated per-account `Retry-After`, so a resumed or newly added account is not ignored until a 24-hour target cooldown expires. An upstream 429 on an API-key provider or on an identified pool account keeps its full `Retry-After`. Regression coverage: `tests/routing/always-on-429-failover.test.ts`.

Subject: [PATCH 28/61] fix(responses): display hosted image results in local
 Codex clients (carry #6233) (#6394)

Carries #6233 by @chiperman onto dev. For loopback-admitted, recognized Codex Responses clients, a completed hosted image_generation_call is projected into an assistant final_answer message with a Markdown link to a validated local artifact (SSE, JSON, and JSON-to-SSE). When the client replays history, on both ordinary requests and remote compaction, generated local links in assistant content are replaced by opaque artifact references before dispatch, so local paths never reach an upstream. Artifacts reuse the image validation, byte budgets and retention rules. They are written exclusively with random names, display state is bounded, and URL results are not downloaded.

Maintainer commits: compaction-path redaction and normalized artifact-link matching (security review finding), plus a structure-doc line-budget move.

Closes #6231

 opencodex decides this by reading Codex own config itself, so the switch does not depend on the
 injected URL or on anything a client sends, and turning it off takes effect without a restart.
 
+### Hosted image results in Codex App
+
+When a routed Responses provider returns a completed hosted `image_generation_call`
+with base64 image data, opencodex saves the validated image under its local
+`artifacts/` directory and delivers a final assistant image message to a locally
+connected Codex client. The image stays outside the collapsible progress section.
+This applies to streaming and non-streaming Responses, without another generation
+request or a change to the selected provider.
+
+When a client replays these generated image messages as assistant history, opencodex
+replaces its generated local image links with opaque artifact references before
+forwarding that history. This protects the display paths without changing the image
+message already shown in the app. It does not redact unrelated user-supplied paths.
+
+This display compatibility requires loopback admission and a recognized Codex client.
+Remote and generic API clients retain the provider's hosted response format.
+Partial previews and URL-only results are not rendered by this compatibility layer.
+Artifacts use the existing retention limit, so save images you want to keep before
+older files are pruned. An invalid image or a failed local write produces a visible
+failure message instead of a broken image link.
+
 ### Built-in image generation (`image_gen`)

 Shared parsing and streaming follow the [request-copy](../transports/byte-accounting.md#request-copy-accounting) and [stream-buffer accounting](../transports/byte-accounting.md#stream-buffer-accounting) contracts. Response-attached WebSocket telemetry follows the [stage record identity contract](../transports/responses-wire-shapes.md#passthrough-sse-stream-shapes-314).
 
+## Hosted Responses image display
+
+For loopback-admitted Codex Responses clients,
+`src/server/responses-hosted-image-display.ts` projects hosted `image_generation_call`
+results into assistant messages with `phase: final_answer` and Markdown links to local
+artifacts. The final phase keeps the image outside collapsible progress output.
+`src/server/responses/passthrough-delivery.ts` applies this projection after continuation
+observers, on the client branch only, for SSE, JSON and JSON synthesized into SSE.
+The SSE projection emits consistent message lifecycle events and terminal snapshots,
+suppresses replaced hosted-image progress frames, and adjusts numeric sequence numbers
+for inserted or removed events, identically in both relay shapes.
+Hosted items in the continuation cache retain their upstream representation; other
+client rewrites keep their existing cache policy. Generic, remotely admitted and non-Responses
+clients do not receive this filesystem projection. Individual image item events without
+a string item id or a valid non-negative integer output index pass through without
+allocating display state, so unidentified items cannot collide at a synthetic index.
+
+Full-history assistant messages can replay the display Markdown without their generated
+item ids. At Responses request preparation and at the remote compaction handler
+(`src/server/responses/compact.ts`), exact generated links become opaque artifact HTTP
+references before routing, helper dispatch and the upstream compact request. A link
+matches when its target, as a plain path or `file://` URL with either separator and dot
+segments resolved, names an `img-codex-<uuid>` image directly inside the current
+artifact directory; on macOS and Windows the comparison also ignores letter case. This
+does not read files and still applies after artifact pruning; unrelated paths, nested
+directories, user messages and tool payloads retain their original content. Local display
+uses filesystem links because remote Markdown media has a separate client safety gate;
+HTTP references here are for upstream context, not a claim of desktop HTTP rendering.
+
+Image data must pass the shared base64, format and byte-budget checks in
+`src/images/artifacts.ts`. Files use random names, exclusive creation and mode 0600;
+the artifact directory uses mode 0700 on creation. Per-response display state is capped
+at 128 image items, with the existing 50 MiB per-image and 100 MiB aggregate decoded
+limits. Exceeding the item cap returns HTTP 502 before streaming or a failed SSE
+terminal after streaming has started. Retention runs after the batch. Failed or invalid results produce a bounded
+display message without reflecting payloads or filesystem errors. URL results and
+partial-image previews are not downloaded or rendered by this projection.

Subject: [PATCH 29/61] fix(spend): name the refused ledger file and condition,
 warn on synced state directories (#6398)

Refs #6314. A ledger file that fails a safety check now raises SpendLedgerFileRefusedError, a SPEND_LEDGER_OWNER_UNAVAILABLE owner error. The error names the file role (journal, journal-compaction, salt) and the failed condition (not-regular-file, symbolic-link, extra-hard-link, foreign-owner, invalid-salt), and never a path, salt, alias or request content. The guard is unchanged.

On macOS, startup now warns once when the state directory resolves inside iCloud Drive, a File Provider folder, or Desktop/Documents while iCloud Desktop & Documents sync appears to be on. A sync service briefly holding a second hard link to the journal turns ordinary requests into intermittent 502s. The warning is advisory and never refuses. A new troubleshooting page explains each condition and the fix.

+title: Spend Ledger Refused in a Synced Folder
+description: Why requests can fail with "Spend-ledger storage could not be opened safely" when the opencodex state directory is inside iCloud Drive or another synced folder, and how to fix it.
+---
+
+Some macOS users saw requests fail intermittently with HTTP 502 and this message, while
+other requests in the same session succeeded:
+
+```text
+Provider unreachable: Spend-ledger storage could not be opened safely.
+```
+
+Current builds say which file and which check refused it, for example:
+
+```text
+Spend-ledger storage could not be opened safely (journal: extra-hard-link).
+```
+
+## What the check is
+
+opencodex keeps a spend ledger in its state directory (`~/.opencodex` by default, or
+`OPENCODEX_HOME`): a journal file, `spend-ledger.jsonl`, and a salt file, `spend-ledger.salt`.
+Before every write it checks that each file is a regular file owned by you, is not a symbolic
+link, and has exactly one directory entry. A second hard link would mean another name elsewhere
+on the volume can see or change the same bytes, so opencodex refuses instead of writing through
+it. This check stays strict on purpose.
+
+| Condition in the message | Meaning |
+| --- | --- |
+| `extra-hard-link` | Another directory entry points at the same file. |
+| `symbolic-link` | The ledger file is a symbolic link. |
+| `not-regular-file` | Something other than a regular file sits at the ledger path. |
+| `foreign-owner` | The file belongs to a different user. |
+| `invalid-salt` | The salt file exists but its content is not a valid salt. |
+
+The role in the message is `journal`, `journal-compaction` (the temporary file written while
+the journal is compacted) or `salt`.
+
+## Why a synced folder triggers it
+
+macOS sync services, including iCloud Drive with "Desktop & Documents Folders" turned on and
+File Provider clients such as OneDrive, Dropbox and Google Drive, can briefly keep a second link
+to a file while they stage or upload a change. If the state directory is inside such a folder,
+the journal can have two links for a moment after an ordinary write. A request that lands in
+that moment is refused, and the next one may succeed. Once the sync settles, the file is back to
+one link, so inspecting it afterwards shows nothing wrong.
+
+At startup opencodex now warns when the state directory resolves inside iCloud Drive
+(`~/Library/Mobile Documents`), a File Provider folder (`~/Library/CloudStorage`), or Desktop
+or Documents while iCloud Desktop & Documents sync appears to be on. The warning is advisory.
+The detection reads the folder layout and can be wrong in either direction.
+
+## Fix
+
+Keep the state directory outside synced folders. The default `~/.opencodex` is not synced.
+
+1. Stop opencodex.
+2. Move or copy the state directory to an unsynced location, for example `~/.opencodex-trial`.
+3. Set `OPENCODEX_HOME` to that location, or unset it to use the default, and start opencodex
+   again.
+
+Do not delete the journal, relax its permissions, or remove the check to make the error go away.
+The journal holds your recorded spend, and the check is what keeps it from being written through
+an unexpected link.
+
+If the message names a condition other than `extra-hard-link`, or the state directory is not in
+a synced folder, please open an issue with the full refusal message. It contains no path,
+account or request content.

Subject: [PATCH 30/61] fix(router): preserve policy authorization across
 fallback redirects (carry #6380) (#6396)

Policy fallback could authorize a redirect from a bounded diagnostic trace or reselect a public alias, letting a retry escape the original eligible provider/model set. Keep the first policy evaluation's complete membership as request-owned state, evaluate retries as concrete candidates, and check the final destination before dispatch. Subagent selection, recovery, alias collisions and virtual wire models stay inside that membership.

The shadow-intercept target is probed without capturing that scope and is captured only when interception is accepted, so a declined policy target never scopes the request's own route.

Carried from #6380.

 A disabled destination, a forward destination, or a key/OAuth destination without usable stored
 credentials keeps the source route's legacy behavior. Under a routing policy, every redirect target
 must itself be a declared eligible candidate, even when it keeps the same provider.
+The initial evaluation's eligible provider/model set remains fixed through fallback and subagent
+recovery. Retries use concrete candidates, so a combo alias cannot replace a candidate's destination.
+Different candidates that resolve to a destination already attempted do not send the turn there again.
+An eligible virtual model keeps its normal wire-model mapping without adding that wire id to the
+profile's allowed candidates. If a local replacement is skipped, fallback retains the last upstream failure.
 Malformed redirect maps are ignored with a warning on load and rejected on configuration writes.
 Redirected routes record `blocked-model-redirect`; omitting the setting leaves routing unchanged.

+Subagent selection and encrypted-task recovery keep that membership; a replacement outside it is
+refused before dispatch, and policy fallback may continue with another originally eligible candidate.
+A shadow-intercept target is probed without that capture and is captured only once interception is
+accepted, so a declined policy target never scopes the request's own route.
+`src/server/responses/policy-fallback.ts` inspects and executes each retry as a concrete candidate,
+so a public combo or profile alias cannot reselect its destination. Redirects remain inside the
+original evaluation, including eligible destinations omitted from the bounded diagnostic trace.
+
+Normal virtual-model wire mapping remains attached to its admitted selector and does not add a new
+eligible model. Policy traversal records settled physical destinations and skips a destination already
+attempted through another candidate or redirect; same-target credential and transient retries retain
+their existing budgets. Local skips preserve the last upstream failure and its log context, including
+route identity, usage, active attempt and spend tracker; preparation-only fields are discarded.
+Completed physical attempt rows remain intact, and final logging settles the last actual send's usage.
+The initial decision remains the selection evidence while physical attempts record execution.
+
+Cancellation, non-replayable responses and committed output keep the
+[shared replay boundaries](responses-failover.md). A local policy refusal is identified by its
+in-process response identity; matching upstream prose or error codes cannot authorize another attempt.
+
+Coverage: `tests/routing/routing-policy-dispatch-scope.test.ts` exercises real request preparation,
+normalization and configured subagent selection with synthetic dispatch. It also covers recovery,
+alias collisions, redirects, bounded traces and virtual models. `tests/routing/routing-policy-fallback.test.ts`
+pins request snapshots, terminal responses, cancellation, credential handoff and attempt accounting.

Subject: [PATCH 31/61] test(config): canonicalize the owner-registry ACL test
 root (macOS) (#6411)

test(config): canonicalize the owner-registry ACL test root (macOS) (#6411)

atomicWriteFileNoFollow names its temp file from the realpath of the registry
directory. On macOS tmpdir() is under /var, a symlink to /private/var, so the
mocked icacls runner's root-prefix assertion threw on the canonical temp path.
The required entry hardening then failed, registerOwnerRegistryHome swallowed the
error, and no entry was written. The test root is now canonicalized with the same
realpathSync the writer uses. Runtime code is unchanged.

Subject: [PATCH 32/61] feat(chatgpt): experimental macOS app-server quota-gate
 shim (split from #5947) (#6361)

Splits the app-server shim out of #5947 by @lcxhh521 as an experimental, macOS-only, default-off feature. ocx chatgpt launch relaunches the ChatGPT desktop app (com.openai.codex) through a launcher that execs the bundled app-server and filters only its stdout. The filter clears plain-quota gate fields on rate-limit messages and leaves workspace, credit and spend-control restrictions and the displayed usage untouched. The bundle is discovered by identifier and accepted only if it is OpenAI-signed (team 2DC432GLL2) and owned by the user or root. The launcher is written atomically, and lines over 8 MiB pass through unparsed. PAC fallback and the local-CA intercept from #5947 are not included.

+title: ChatGPT Desktop app-server shim (experimental)
+description: An opt-in macOS experiment that rewrites plain-quota gate fields on the bundled app-server stdout pipe.
+---
+
+This experiment is **macOS only and off by default**. It filters the bundled ChatGPT
+app-server's JSON-RPC stdout to open known plain-quota gates. It does not increase
+an account's quota or make an upstream service accept a request it refuses.
+
+Enable it in your OpenCodex `config.json`:
+
+```json
+{
+  "chatgptDesktop": { "appServerShim": true }
+}
+```
+
+Then run:
+
+```bash
+ocx chatgpt launch
+ocx chatgpt status
+```
+
+`launch` creates an executable launcher under the OpenCodex config directory,
+quits ChatGPT if it is running, and relaunches it with
+`open -a <bundle> --env CODEX_CLI_PATH=<launcher>`. The app is found by its bundle
+identifier, `com.openai.codex`, so an install in `~/Applications` or on another
+volume works, and another app that shares the "ChatGPT" name is never quit or
+opened. Save ongoing work first: this
+restarts the app. It does not require a running OpenCodex proxy.
+
+To remove the launcher and relaunch without the override:
+
+```bash
+ocx chatgpt restore
+```
+
+Restore leaves the config flag as configured. Set `chatgptDesktop.appServerShim`
+to `false` or remove it to disable future explicit shim launches. Normal launches
+from Dock or Spotlight do not apply the shim automatically.
+
+## Rewrite boundary
+
+Only `account/rateLimits/updated` notifications and responses whose top-level
+result contains `rateLimits`, `rateLimitsByLimitId`, or `ordinaryUsageAllowed`
+are eligible. Plain `rate_limit_reached` markers are cleared; known quota gate
+flags (`allowed`, `limit_reached` / `limitReached`, `ordinaryUsageAllowed`) are
+opened only with plain-quota evidence (a cleared plain reached type or a window at
+100%). A flag closed for a reason the payload does not show stays closed. Workspace,
+credit, unknown reached-type and spend-control
+restrictions keep the usage gate closed.
+
+Displayed usage stays honest: percentages, reset times, window durations, plan
+information and other display fields stay as received. Unrelated JSON-RPC
+messages, nested tool output, conversation send-block metadata and malformed
+lines pass through. Only changed lines are serialized again; other bytes retain
+their original encoding and line endings. Stdin, stderr and the real binary's
+exit status retain their direct connection to the app.
+
+## Executable and environment security
+
+The generated launcher has mode `0755` and embeds the current OpenCodex executable
+and, for source installs, the CLI entry path. `CODEX_CLI_PATH` tells ChatGPT to
+execute this launcher instead of its bundled binary directly. Keep the launcher,
+its config directory, and the OpenCodex installation under your control: changing
+these executable paths changes code the app runs. The launcher still `exec`s the
+bundled binary of the discovered bundle; if that bundle has no app-server binary,
+`launch` refuses instead of writing a launcher.
+
+Before writing the launcher, `launch` also checks that the bundle and its
+app-server binary are owned by you or root, are not writable by group or others,
+and pass strict code-signature verification under OpenAI's team ID
+(`2DC432GLL2`). A bundle that fails any of these is refused, so a copy placed by
+another account cannot be made to run inside your session. The launcher file is
+written to a temporary file and renamed into place; an existing symbolic link at
+that path is replaced, not followed.
+
+This integration installs no certificate, network listener, PAC, or background
+watcher. It does not log the app's messages or environment. Status reports whether
+the running ChatGPT bundle process carries the expected launcher override.
+
+## Failure behavior and known limits
+
+A failed precondition or a failed self-test runs the original binary with untouched stdout.
+A filter that passes the self-test and then dies mid-session closes the pipe.
+Expected (not yet validated against the bundled app-server): the server gets SIGPIPE or a write error and Desktop respawns it through the same launcher.
+The filter's passthrough mode limits this to an exit/crash case: a rewrite exception
+passes its line through, and an unexpected rewrite-machinery failure switches the
+remaining stream to raw bytes.
+
+The experiment depends on the bundled binary path, the app honoring
+`CODEX_CLI_PATH`, and current RPC field shapes. Updates may change these. A moved
+or removed OpenCodex installation fails the launcher preflight and runs the
+original binary. Run `ocx chatgpt launch` again after relocating the installation.
+If an app update moves or removes the bundled app-server binary itself, the
+launcher cannot start it: it prints a message naming `ocx chatgpt launch` and
+`ocx chatgpt restore` on stderr and exits, and Desktop cannot start its
+app-server until you run one of them. A single output line longer than 8 MiB is
+passed through unparsed rather than buffered.
+
+This standalone shim does not rewrite conversation metadata or route model calls.
+Other app gates or upstream refusals can still prevent sending. Evidence reported
+on an exhausted Plus account also used an intercept, so it does not establish
+that this shim alone resolves every desktop send lock.

+# ChatGPT Desktop app-server shim
+
+The experimental macOS integration is owned by `src/chatgpt/` and exposed through
+`src/cli/chatgpt-command.ts`. It is default off and requires
+`chatgptDesktop.appServerShim === true` for an explicit launch. Its config leaf
+accepts only an optional boolean; malformed reads disable the leaf, while live
+writes reject malformed values and unknown fields.
+
+The launcher under the config directory re-enters the current CLI using
+`process.execPath` and `selfLaunchArgv()`. Its hidden internal filter command stays
+out of the public command registry and generated skill surface. Source installs
+include the CLI entry argument; compiled builds use only the executable and
+internal command arguments.
+
+The launcher checks macOS, executable presence and a successful filter self-test,
+then replaces itself with the bundled app-server using shell exec. Only stdout
+passes through the filter. Stdin, stderr, process identity and the real server's
+exit status retain the direct app/server relationship.
+
+A failed precondition or a failed self-test runs the original binary with untouched stdout.
+A filter that passes the self-test and then dies mid-session closes the pipe.
+Expected (not yet validated against the bundled app-server): the server gets SIGPIPE or a write error and Desktop respawns it through the same launcher.
+The filter's passthrough mode limits this to an exit/crash case.
+
+The pure gate rewrite changes known plain-quota fields only in eligible JSON-RPC
+rate-limit notifications and top-level rate-limit results. Workspace, credit,
+unknown reached-type and spend-control restrictions preserve closed gate flags.
+Both the rate-limit flags and `ordinaryUsageAllowed` open only where the subtree shows
+plain-quota evidence: a cleared plain reached type or a usage window at 100%.
+Usage percentages, resets and window durations remain accurate. Unrelated messages
+and malformed lines remain byte-identical; changed lines are reserialized.
+A per-line rewrite exception preserves that line. A failure in the framing/rewrite
+machinery preserves buffered bytes and switches the rest of the stream to raw
+passthrough. Output-write failures propagate; they are not rewrite failures.
+A partial line is held as a list of chunks and joined once at its newline, so a long
+line split across many pipe reads costs linear copying.
+A line longer than `MAX_FILTERED_LINE_BYTES` (8 MiB) is never buffered or parsed: the
+held bytes and the rest of that line stream through raw, and filtering resumes after
+its newline.
+
+The app is discovered and confirmed by bundle identifier through
+`darwinDesktopAppAdapter.discover` (`src/codex/desktop-app/darwin.ts`). Launch derives
+the bundled app-server binary from that root (`resolveChatgptCodexBinary`) and refuses
+when none exists or when `untrustedChatgptBundleReason`
+(`src/chatgpt/app-server-shim/bundle-trust.ts`) reports the bundle or binary as owned
+by another user, group/other-writable, unsigned, or signed by a team other than
+OpenAI's. It writes the mode-0755 executable through an exclusive temp file and a
+rename (never through a symbolic link), quits the bundle by id, waits for this user's
+instance to exit, then opens the same bundle path with the launcher in CODEX_CLI_PATH.
+The launcher itself exits 127 with a stderr hint when the recorded binary is gone.
+Restore relaunches without
+that override and removes the launcher only after open succeeds. Status reports
+the experimental flag, launcher presence, and the verified bundle process's override
+without printing its environment. Other platforms reject all three operations.
+
+The launcher and its executable paths are local code-execution inputs. This
+integration installs no network listener, CA, PAC or background watcher, and
+starts no proxy timer. Explicit launches are its only activation point.
+
+Tests cover rewriting, byte framing, passthrough degradation, source/compiled
+launcher text, stub launcher execution, hidden preflight, and strict config writes
+in tests/clients/desktop-*.test.ts. Pipe-crash behavior is mock evidence only;
+no bundled-app respawn guarantee is asserted.

Subject: [PATCH 33/61] fix(codex): exclude macOS Electron helpers from client
 diagnostics (carry #6296) (#6393)

fix(codex): exclude macOS Electron helpers from client diagnostics (carry #6296) (#6393)

On macOS the client classifier split unquoted ps args at the first space, so
Codex.app's "Codex Framework.framework" helpers (crashpad, renderer, utility)
produced an argv0 named Codex and were listed as pending-restart Codex clients.
A full executable path now beats an argv0 guessed from args, the basename-only
split framework pair is rejected, and the macOS busy probe reads comm and args
separately and joins them by PID. Closes #6291.

Carried from #6296.

Subject: [PATCH 34/61] fix(update): check and pin the npm cache root before
 staging (#6288) (#6395)

fix(update): check and pin the npm cache root before staging (#6288) (#6395)

The npm cache preflight returned windows_skip before inspecting anything, so a
dangling %LOCALAPPDATA%\npm-cache junction surfaced only as ENOTDIR from the staged
install after the proxy had stopped. Staging's --prefix also moved npm's
globalconfig, which dropped a cache= setting from the user's global npmrc.

The cache root (or the nearest existing ancestor) must now resolve to a directory
on every platform. A file in its place is cache_root_not_directory and a dangling
link or junction is cache_root_dangling_link, each with fixed path-free guidance.
On Windows only those two reasons block; inconclusive results keep the previous
skip. The launcher resolves npm config get cache --global from the home directory,
checks that path, and pins it into the stage with --cache. On Windows a path with
cmd.exe metacharacters is refused and left unpinned.

Closes #6288.

+`ENOTDIR` on `mkdir` means npm tried to create a folder where a path component was a file, or
+a link whose target no longer exists. One confirmed cause
+([#6288](https://github.com/lidge-jun/opencodex/issues/6288)) is a `%LOCALAPPDATA%\npm-cache`
+junction that pointed to another drive after the target folder had been deleted or the drive had
+been removed.
+
+The updater checks npm's cache folder before it stops the proxy, and the npm staging install uses
+the same folder that `npm config get cache` reports. If the cache folder cannot be used, the update
+stops with `cache_root_dangling_link` or `cache_root_not_directory` and leaves the proxy running:
+
+- `cache_root_dangling_link`: the cache folder is a link or junction whose target is missing.
+  Recreate the target folder, or remove the link so npm can create a normal folder.
+- `cache_root_not_directory`: the cache folder, or a folder above it, is a file or sits on a drive
+  that is not available. Move the file aside, or point npm at another cache with
+  `npm config set cache <folder>`.
+
+Then run `ocx update` again. If `ENOTDIR` persists after the check passes, open an issue with the
+full terminal output of `ocx update` and the output of `npm config get prefix` and
+`npm config get cache`.

 from a marker: the marker is not an authorization secret, and a neighbouring writer could
 replace a previously checked pathname with a link before traversal.
 
+Before any tray or proxy stop, `src/update/npm-cache-preflight.mjs` checks npm's cache on every
+platform (#6288). The cache root, or the nearest existing folder npm would create it under, must
+resolve to a directory. A file in its place is `cache_root_not_directory`, and a link or Windows
+junction whose target is gone is `cache_root_dangling_link`; both abort with fixed guidance that
+names neither the path nor npm output. Windows runs only this root check, because it has no uid
+or Unix owner bits, while POSIX also runs the bounded ownership/mode walk. Windows skipped the
+gate entirely before #6288, so there only those two root reasons block; an unresolvable npm cache
+path, a worker timeout or any other inconclusive result returns `windows_skip` and the update
+proceeds unpinned as before. POSIX keeps failing closed on them. The npm launcher
+resolves `npm config get cache --global` once, from the home directory and with the environment
+staging uses, checks that path and passes it to the stage as `--cache`. Global mode and the home
+directory keep a project `.npmrc` in the caller's cwd from choosing the pinned cache, matching the
+`npm install -g` stage that never reads project config. On Windows a resolved path containing
+`" % ! ^ & | < >` is refused rather than escaped, because `npm.cmd` re-parses `%*` after our
+cmd.exe quoting; the update then proceeds unpinned. The pin is required: `--prefix <stage>` moves npm's
+globalconfig to `<stage>/etc/npmrc`, so a `cache=` from the operator's global npmrc would
+otherwise be dropped and staging would use npm's default root, which the pre-flight never
+checked (`tests/update/update-npm-cache-preflight.test.ts`,
+`tests/update/update-transactional.test.ts`).

 The probe ceilings are module-load constants in `src/server/proxy-liveness.ts`: 750 ms for the
 shared default and 1500 ms (three attempts) for `SERVICE_STOP_LIVENESS` and
 `START_OWNERSHIP_LIVENESS`. `OCX_PROBE_TIMEOUT_MS` (whole milliseconds, 1 to 30000) only raises

Subject: [PATCH 35/61] fix(service): tolerate locale dates in Windows service
 wrappers (carry #6298) (#6391)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

fix(service): tolerate locale dates in Windows service wrappers (carry #6298) (#6391)

On locales whose short date contains parentheses (ko-KR "2026-09-30(수)", ja-JP
"2026/09/19 (土)"), cmd.exe expands %DATE% while parsing a parenthesized block, so
the ")" closed the block early and the generated service wrapper aborted before it
launched Bun, on every start. The timestamped log lines now sit at top-level labels
(:bun_missing, :cli_missing, :backup_restored), outside any block. Exit code 3, the
stay-out/restart contract, transactional-backup recovery and disabled delayed
expansion are unchanged. Run "ocx service repair" after upgrading to regenerate an
installed wrapper. Closes #6290; same defect as #5093.

Carried from #6298.

Subject: [PATCH 36/61] feat(transport): carry opt-in Antigravity TLS profile
 onto provider egress (carry #3741) (#6359)

Carries #3741 by @yansigit: an opt-in tlsProfile: "antigravity-browser" for the canonical Google Antigravity OAuth provider. It sends requests through the native wreq-js transport with a browser TLS fingerprint. The profile only reaches canonical Cloud Code HTTPS hosts, keeps manual redirects, carries decided and inherited proxy routes, and refuses direct routes while proxy variables are set. It also preserves abort identity and reports pending, active or failed on /api/providers. Users enable it at their own risk. Maintainer follow-ups: transport errors no longer show proxy userinfo, a caller cancellation no longer marks the profile failed, and provider-routes.ts stays under the line ceiling.

 | `requestPacing?` | `{ enabled, requestsPerMinute?, minIntervalMs?, maxConcurrentRequests?, models? }` | Optional client-side outbound request-start pacing, separate from upstream usage, billing, and rate-limit indicators. RPM is converted to an even interval; `minIntervalMs` may impose a longer interval. `maxConcurrentRequests` is a positive integer cap on in-flight requests. A provider or model rule may use the concurrency cap alone; provider limits apply across all models, while `models` entries use exact upstream model IDs (for example `nvidia/llama-3.1-nemotron-ultra-253b-v1`) and can only add delay or narrow concurrency. Queue waits do not consume the upstream response-header timeout. HTTP and explicit adapter `fetchResponse`/`runTurn` dispatches are covered. A concurrency-capped canonical Responses WebSocket turn uses HTTP/SSE so its lease can be released when the response body completes, errors, or is cancelled. For `runTurn` adapters, including Cursor, the cap counts active turns rather than physical sends: RunSSE and BidiAppend may overlap within one turn, while another turn waits. Follow-up sends still obey start intervals. |
 | `upstreamHttpVersion?` | `"auto" \| "http1.1" \| "h1" \| "http2" \| "h2"` | Pin the HTTP version used for upstream requests to this provider. Defaults to `auto`, which lets Bun negotiate. An explicit pin requires an HTTPS target and fails locally when it cannot be honored. Set `http1.1` when a provider's HTTP/2 SSE stream stalls instead of delivering events — the symptom is a long-running streaming request that produces nothing and eventually times out. For Cursor, `http1.1`/`h1` selects its `RunSSE` + `BidiAppend` compatibility transport for inference and also pins live model discovery. Management `POST`/`PATCH` accept `null` to clear it back to `auto`. |
+| `tlsProfile?` | `"antigravity-browser"` | **Use at your own risk.** Opt-in browser-like TLS handshake (through the optional `wreq-js` dependency) for the canonical `google-antigravity` OAuth provider. It changes only how the connection looks on the wire; it is not an official Google client, and it does not change what Google's terms allow. Google can still detect, rate-limit, suspend, or ban the account you signed in with, and you alone carry that risk. It is off by default and accepted only with the Google adapter, Cloud Code Assist mode, and Google's canonical HTTPS Antigravity hosts. Redirects stay manual. The provider's own `proxy`/`noProxy` route is carried by the TLS transport; a route it cannot keep fails the request instead of leaving by another path, which includes any direct route while `HTTP_PROXY`, `HTTPS_PROXY`, or `ALL_PROXY` is set. `GET /api/providers` reports the profile state as `pending`, `active`, or `failed`. Omitting the field keeps the normal Bun transport and never loads the dependency. |
 | `responsesPath?` | `string` | Relative resource path for key-auth `openai-responses` requests. It must start with `/` and contain no scheme, query, or fragment. |
 | `chatCompletionsPath?` | `string` | Relative resource path for `openai-chat` requests, the mirror of `responsesPath` and subject to the same shape rules. Needed when one upstream serves Chat Completions and Responses under different prefixes: a per-model wire override changes the adapter and leaves `baseUrl` alone, so without this an opted-in Chat request would be sent to the Responses base. Z.AI is the shipped example. |
 | `allowEncryptedV2AgentTasks?` | `boolean` | Disabled by default. Trust a direct key-auth `openai-responses` provider to consume or relay opaque encrypted V2 sub-agent tasks unchanged. Eligible routes skip `agentTaskRecovery`; all other routes keep the existing recovery or fail-closed behavior. OpenCodex does not decrypt, translate, or recover tasks sent through this opt-in. |

Subject: [PATCH 37/61] =?UTF-8?q?feat(combos):=20JEV=20decision=20methods?=
 =?UTF-8?q?=20=E2=80=94=20TypeSafe,=20System=20One=20server,=20or=20any=20?=

Carries #6302 (SeongwoongCho), #6185 (yxr1995-maker) and #6275 (codingbooo) as one maintainer PR. A JEV combo's decision can now come from TypeSafe (the default, with byte-identical requests), from a self-hosted System One-compatible server such as Ollama tev1 (a jev-decision provider row with its own key, private network only when allowPrivateNetwork is set, and environment keys only for the official TypeSafe URL), or from any model opencodex already routes. Every option shares the same timeout, size bounds, allowlist validation and fail-open behavior, and refuses a decision model that points back at itself or at a JEV combo. The decision method is set in the Combos detail panel under Models, alongside a Test probe, discovery and per-backend usage statistics. The CLI and management API expose the same controls.

Maintainer follow-ups fix the open review findings:
- Provider deletion resolves aliased and default-routed decision models.
- The config schema no longer imports the server's model-row parser.
- The decision turn sends the model's lowest declared reasoning effort and ignores a leading think block in the reply.
- decision-test refuses unusable System One rows by name.
- Dashboard selectors are normalized together.
- Documentation, the README anchor, tr/vi wording and the README locale hashes are updated.

+# 261001 JEV decision routing
+
+Status: open. Loop session `01a0f5d4-89c4-7973-9b32-3cadcb4f0929`, branch `codex/jev-decision-routing` from `origin/dev` `64294638a6`.
+
+A `strategy: "jev"` combo asks a decision service which target and reasoning effort should take the next call. Today that service is always a System One endpoint. This unit turns the transport into a pluggable **decision backend** so the same state and candidate list can be answered either by a System One server or by any model opencodex already routes.
+
+## Sources carried
+
+| Source | Author | What is carried | What is not |
+|---|---|---|---|
+| #6302 | SeongwoongCho | Commits `d60975ee1b`..`304bd4aaee` (self-hosted `jev-decision` rows, `decisionProvider`, `decisionTimeoutMs`, cleartext loopback opt-in, GUI select, save/PATCH guards) cherry-picked with authorship. CLI partial-update fixes `2740904285` and `af1b035e7a`, adapted. | Level mode, quota signals, quota warmer, configurable wording (`4b5c636db2` and later). They go back to the author as a rebase onto this PR. |
+| #6185 | yxr1995-maker | Pure discovery helpers (`decision-discovery.ts`: model hint, `/systemone` endpoint derivation, dedupe) and a read-only discovery endpoint; regression cases proving environment TypeSafe keys never reach another destination. | `Decisions.tsx` page and sidebar tab, automatic destination scan, global `JEV_MODEL` override, `jev-opencode` preset (MAINTAINERS.md: a new preset is a credential-destination change needing primary-source evidence; OpenCode zen is documented as an ordinary row), adopt endpoint that copies credentials. |
+| #6275 | codingbooo | Its custom-endpoint regression, adapted to a non-`jev` row id (a `jev` row stays pinned to TypeSafe by design). | The `isConfiguredJev` retargeting of the `jev` row. |
+
+All three authors get `Co-authored-by` trailers on the squash.
+
+## Decisions
+
+- **D1 config.** Combo fields: `decisionProvider` (existing), `decisionModel` (new, opencodex route string), `decisionTimeoutMs` (existing). The backend is derived, never stored: `decisionModel` set → `model`; `decisionProvider` set and not `jev` → `systemone`; otherwise → `typesafe`. Setting both is a config error. Existing combos need no change.
+- **D2 backend seam.** `resolveJevDecision` becomes a dispatcher over two backends that share one runtime envelope (candidate bounds, state check, deadline, abort handling, fail-open): System One (unchanged bytes on the TypeSafe path) and Model (prompt → JSON `{"choice": "<key>"}`). Level/quota modes can later add a question builder on top of the same envelope.
+- **D3 model invocation.** The pure backend takes an injected `invoke(model, prompt, signal)`. Server glue in `src/server/responses/jev-model-invoke.ts` runs a fresh internal `/v1/responses` turn through the dispatcher's `handleResponses` with its own send budget, its own turn lease (`tryAdmitTurn`), a detached log context whose spend tracker is settled, the parent's admission, and no parent history/tools/session headers. The response is read through `readBoundedResponseBytes` (64 KiB) and `createSseInspector`.
+- **D4 recursion.** A decision model that resolves (canonical `combo/<id>` or alias, after synthetic selector stripping) to its own combo or to any `strategy: "jev"` combo is refused by `comboConfigIssues` against the prospective combo map. At runtime an `internalDecisionCall` flag refuses combo reentry defensively and fails open.
+- **D5 stats.** `PersistedJevDecisionV1` gains optional `backend`; old rows keep parsing and land in an `unknown` bucket. Aggregates add per-backend count and average latency.
+- **D6 surfaces.** CLI `ocx combo set --decision-model <route|->`; management PUT/POST combos accept `decisionModel`; `POST /api/combos/decision-test` probes an unsaved decision configuration with synthetic candidates; `GET /api/combos/decision-discovery` lists configured System One rows and catalog rows that look like decision models with the derived endpoint.
+- **D7 dashboard.** A `Decision method` section in the combo detail panel and add dialog (TypeSafe / System One-compatible server / opencodex model, timeout, Test, recent stats). No separate page.

+# 010 wp1: decision backend seam and System One backend
+
+Revalidate against the tree at the start of wp1; line numbers below are from `80efc0e373`.
+
+## Files
+
+### MODIFY `src/combos/jev.ts`
+
+- Export `type JevDecisionBackend = "typesafe" | "systemone" | "model"`.
+- `JevDecision` gains `backend: JevDecisionBackend`.
+- Extract the shared envelope into exported helpers (stay in this file to keep imports flat):
+  - `jevDecisionTimeoutMs(value?: number): number` — bounds check now inline in `resolveJevDecision`.
+  - `jevDecisionPreflight(options): { failed?: gate; state?: Record<string, unknown> }` — empty candidates → `no_choices`; `candidatesFitRequestBounds` → `invalid`; `buildJevState` + `hasJevDecisionState` → `no_state`.
+  - `jevRouteChoiceKeys(candidates): string[]` exporting the allowlist (wrapper over `candidateOptions`), and `jevRouteOption(candidates, key)` returning `{targetKey, effort}`.
+- Rename the System One transport body to `resolveJevSystemOneDecision(options, endpoint)`; behavior identical. Byte-for-byte TypeSafe request (`model`, `state`, `questions`) keeps the existing body-equality test green.
+- `resolveJevDecision(options)` becomes the dispatcher: `options.decisionModel` → model backend (wp2; until then not reachable), else System One. Every returned decision carries `backend`: `decisionProvider` absent or `jev` → `typesafe`, otherwise `systemone`.
+- `ResolveJevDecisionOptions` gains `decisionModel?: string` and `invokeModel?: JevModelInvoke` (type declared in wp2's module; in wp1 declare the type here and re-export).
+
+### MODIFY `src/usage/jev-stats.ts`
+
+- `PersistedJevDecisionV1.backend?: JevDecisionBackend`.
+- `normalizePersistedJevDecision`: copy `backend` only when it is one of the three values; anything else is dropped without rejecting the row.
+- `JevStatsResponse` gains `backends: Array<{ backend: JevDecisionBackend | "unknown"; decisions: number; applied: number; averageLatencyMs: number | null }>` (fixed order typesafe, systemone, model, unknown; zero rows omitted).
+- `StreamingJevStatsAccumulator`: per-backend counters in `add`, deep copy in `clone`, projection in `summarize`.
+
+### MODIFY `src/server/responses/core-combo.ts` (JEV block ~517-575)
+
+- Persist `backend: decision.backend` in `logCtx.jevDecision` and in the debug line. Exception path: backend derived via exported `jevDecisionBackendFor(combo)`.
+
+### MODIFY `src/combos/index.ts`
+
+- Re-export the new helpers/types.
+
+### NEW `src/server/management/decision-discovery.ts` (from #6185, pure)
+
+- `DECISION_MODEL_HINT`, `isDecisionModelCandidate(row, query)`, `systemOneEndpoint(baseUrl)`, `uniqueDiscoveryCandidates(rows, query)` carried as written in #6185 `5ffb4c1ba9`.
+
+## Tests
+
+- MODIFY `tests/routing/jev-decision.test.ts`: assert `backend` on apply and fail-open decisions for TypeSafe and a self-hosted row; add #6275's custom endpoint regression adapted to row id `custom-decider` over HTTPS (custom URL, model, own bearer, no TypeSafe env key).
+- NEW `tests/routing/jev-decision-destination.test.ts` (cases from #6185): `TYPESAFE_API_KEY`/`JEV_API_KEY` set in env never appear in headers sent to a self-hosted row; a self-hosted row whose apiKey references those env names is unusable (`missing_key`, no send); a `jev` row with a foreign baseUrl still posts to TypeSafe.
+- NEW `tests/server/decision-discovery.test.ts` (from #6185): hint, query override, endpoint derivation, dedupe.
+- MODIFY `tests/usage/jev-stats*.test.ts` (locate): old row without backend parses; invalid backend dropped; backend buckets after clone+add.
+- Register new test files in `scripts/test-layout/layout.json` and `tests/fixtures/test-layout-expected.json`.
+
+## Accept
+
+- `bun test tests/routing/jev-decision.test.ts tests/routing/jev-decision-destination.test.ts tests/routing/jev-decision-provider-combo.test.ts tests/server/server-jev-combo-e2e.test.ts tests/server/decision-discovery.test.ts` + usage jev-stats tests pass.
+- TypeSafe body-equality test unchanged and green (activation: TypeSafe env key set, default combo).
+- `bun run typecheck` 0.

+# 020 wp2: model backend, validation, CLI and management surfaces
+
+## NEW `src/combos/jev-model-backend.ts` (pure, no server imports)
+
+```ts
+export type JevModelInvoke = (request: { model: string; instructions: string; input: string; signal: AbortSignal })
+  => Promise<{ text: string; usage?: Record<string, number> }>;
+export const JEV_MODEL_INSTRUCTIONS: string; // fixed system text: pick exactly one key, reply {"choice":"<key>"} only
+export function buildJevModelPrompt(state: Record<string, unknown>, candidates: readonly JevCandidate[]): string;
+export function parseJevModelChoice(text: string, allowed: ReadonlySet<string>): string; // throws on anything else
+export async function resolveJevModelDecision(options: ResolveJevDecisionOptions & { decisionModel: string; invokeModel: JevModelInvoke }): Promise<JevDecision>;
+```
+
+- Prompt = JSON text `{ state, options: { "<target>:<effort>": "<criterion description>" , ... } }` reusing `buildJevState` and the same option keys as System One (`candidateOptions`). Max 64 options, request ≤ 64 KiB (UTF-8, prompt + instructions) else `invalid`. Fewer than 1 option → `no_choices`.
+- Parser: trim; strip one surrounding ```json fence; `JSON.parse`; require object with string `choice` in allowlist; also accept a bare quoted string key. Text > 4 KiB → `malformed`. Unknown key → `invalid`. Non-JSON → `malformed`.
+- Errors map: invoke throws `JevModelInvokeError{gate:"http"|"network"|"malformed"|"missing_key"}` → that gate; deadline → `timeout`; caller abort rethrown by identity. `backend: "model"`. Usage keys normalized like System One (`inputTokens/outputTokens`).
+
+## NEW `src/server/responses/jev-model-invoke.ts`
+
+`createJevModelInvoker({ req, config, options, handleResponses }): JevModelInvoke`:
+- Body `{ model, stream: true, store: false, instructions, input: [{role:"user",content:[{type:"input_text",text}]}], tools: [] }`.
+- Headers: `content-type` plus `authorization` only when the parent carried it (credential ownership stays with core-auth). No session/thread/turn headers.
+- Options: `{ abortSignal: signal, admission: options.admission, codexAuthPolicy: options.codexAuthPolicy, sendBudget: createInferenceSendBudget(req, childLog), turnAdmissionLease: lease, internalDecisionCall: true }`; lease from `tryAdmitTurn()`, missing lease → throw gate `network` (fail-open); released in `finally`.
+- `childLog = { model, provider: "unknown", inboundProtocol: "responses" }`; settle its spend tracker in `finally` with measured usage.
+- Read: non-2xx → `http` (cancel body); `readBoundedResponseBytes(64 KiB)` oversize → `malformed`; SSE via `createSseInspector` completed object, JSON via fatal decode; status must be `completed`; extract `output[].content[].type==="output_text"` text.
+
+## MODIFY `src/server/responses/core-options.ts`, `request-prepare.ts`
+
+- `HandleResponsesOptions.internalDecisionCall?: boolean`.
+- In request preparation: when set, skip shadow interception and refuse a route that resolves to a combo (return 400 `invalid_request_error`), so a decision call can never recurse.
+
+## MODIFY `src/server/responses/core-combo.ts`
+
+- Pass `decisionModel` and `invokeModel: createJevModelInvoker({ req, config, options, handleResponses: requestDispatchers.handleResponses })` into `resolveJevDecision`.
+
+## Validation
+
+- `src/types/config.ts` `OcxComboConfig.decisionModel?: string | null`; `src/combos/types.ts` `NormalizedComboConfig.decisionModel?`, normalize trims.
+- `comboConfigIssues` gains `options.combos?` (prospective map). Rules: non-empty ≤ 512 chars; only with strategy `jev`; not together with a non-null `decisionProvider`; strip synthetic selector (`parseSyntheticRowId`) then `resolveComboId` — reject when it is this combo (by id or any of its aliases in the prospective entry) or any combo whose strategy is `jev`.
+- Config schema (`config-schema.ts` ~720) passes the full combos map. Management PUT/POST passes `nextCombos` and revalidates every other combo's `decisionModel` when a combo changes strategy/alias.
+- Save-time: `decisionModelRouteError(config, comboId, model)` in `src/server/management/decision-model-validation.ts` uses `previewRouteModel`; refuses unroutable models and `jev-decision` adapter rows.
+- `combo-routes.ts` omission preservation for `decisionModel`; selecting one selector with explicit null clears the other.
+- `provider-id-rewrite.ts` rewrites the provider prefix of `decisionModel`; `comboDependsOnProvider` counts it (DELETE guard).
+
+## CLI `src/cli/combo.ts`
+
+- `--decision-model <route|->`; reject with `--decision-provider` non-`-`; setting one sends `null` for the other. Carry the partial-update fixes (`2740904285`, `af1b035e7a`): `set` without `--targets` GETs and merges the existing row, filtering null listing fields; drop JEV fields when strategy changes away from `jev`.
+
+## Management
+
+- NEW route `POST /api/combos/decision-test` in `combo-routes.ts` (registered in route-registry with read-only mutation metadata): body `{ decisionProvider?, decisionModel?, decisionTimeoutMs? }`; validates like save; runs `resolveJevDecision` with two synthetic candidates (`probe/a:low`, `probe/a:high`) and a fixed probe task; returns `{ ok, backend, gate, latencyMs }`. Model backend uses `createJevModelInvoker` with a synthetic local Request.
+- NEW route `GET /api/combos/decision-discovery?q=`: `{ configured: [{ id, url, model, usable, issue? }], discovered: [{ provider, model, endpoint }] }` from config rows and the model catalog via the #6185 helpers. No probe, no adoption.
+
+## Tests
+
+- NEW `tests/routing/jev-model-backend.test.ts`: prompt shape and bounds; parser (fenced, bare, unknown, oversize, non-JSON); fail-open gates; timeout; caller abort rethrow; backend tag.
+- NEW `tests/server/server-jev-model-decision-e2e.test.ts`: loopback Bun.serve upstream for an ordinary provider; jev combo with `decisionModel` → decision request reaches that provider without parent tools/history and the chosen target serves the turn; decision provider returning garbage → fail-open to first target; separate send budget (parent target still sends).
+- MODIFY combo validation tests: self id, self alias in same PUT, other jev combo alias, non-jev combo allowed, both selectors rejected, strategy change of referenced combo rejected.
+- CLI test: `--decision-model`, conflict, partial update keeps targets.
+- decision-test route test for both backends (mocked post / invoker).

+
+## Reflection amendments (architect MISALIGNED → folded)
+
+- R1 recursion: the runtime guard refuses only self/JEV combos (non-JEV combos are legitimate decision models). With `internalDecisionCall`, request preparation skips shadow interception at both sites and memory-model rewriting, and refuses a resolved JEV combo before the `handleComboResponses` dispatch; the flag rides into combo children through options.
+- R2 auth: forward `authorization` together with `chatgpt-account-id` when the parent carried them; never session/thread/turn headers.
+- R3 helpers: `jevDecisionBackendFor(combo: { decisionProvider?: string; decisionModel?: string }): JevDecisionBackend` exported from `src/combos/jev.ts`. `class JevModelInvokeError extends Error { gate: "http" | "network" | "malformed" | "missing_key" }` exported from `src/combos/jev-model-backend.ts`. Validation stays import-free: `comboConfigIssues` options gain `normalizeDecisionModel?: (model: string) => string`; management and config schema inject a wrapper over `parseSyntheticRowId(id, config)`; default is identity.
+- R4 prompt: `src/combos/jev.ts` exports `jevRouteOptions(candidates): Array<{ key; targetKey; effort; description }>` (wraps `candidateOptions` + `criterionDescription`); both backends use it. Bounds: ≤ 64 candidates (existing) and ≤ 64 expanded options for the model backend.
+- R5 bounds: the invoker checks the complete serialized Responses body ≤ 64 KiB, passes the deadline-combined signal to `readBoundedResponseBytes`, cancels non-2xx bodies, rejects `error`/non-completed, extracts only `message` → `output_text`. Tests cover lease release and spend settlement.
+- R6 field chains: decisionModel — CLI/add dialog → PUT → `comboConfigIssues`/normalize (sparse) → config write/reload → GET `/api/combos` → GUI `parseComboList` → `executeComboResponses`. backend — `resolveJevDecision` → `logCtx.jevDecision` → request-log persist (`normalizePersistedJevDecision` in request-log and usage/log) → hydration → accumulator add/clone → `/api/usage?jev=1` → GUI `JevStatsResponse` type and panel. A round-trip test exists for each chain; `jevAutoDraft` keeps no decisionModel.
+
+
+## Audit amendments (A round 1 FAIL → folded)
+
+- B1 credentials (supersedes R2). The decision request carries **no** caller credential: no `authorization`, `chatgpt-account-id`, `x-api-key` or proxy admission header is copied, and the invoker passes `callerDirectAuth: null`, `openAiSidecarAuth: null`, `nativeCallerAuth: null` explicitly so `handleResponses` captures nothing. Only the parent's typed `admission` (scope enforcement) rides along. The decision model therefore runs on credentials configured on provider rows, as the design requires ("reuse existing provider credentials; no new credentials"). A route that would need the caller's own bearer (keyless Cursor, caller-owned ChatGPT forward) fails and the decision fails open; docs say so. `request-prepare`/`core-auth` treat `internalDecisionCall` as a credential-domain boundary (no caller-credential restoration). Negative tests: parent opaque bearer, proxy admission secret, and ChatGPT bearer+account id are absent from the upstream request of a decision model routed to a custom loopback provider; a keyless caller-auth provider yields fail-open with no send of the parent bearer.
+- B2 byte proof. Before any refactor in wp1, generate `tests/fixtures/jev-typesafe-request-golden.json` from the current implementation (fixed body, candidates incl. operator note, deterministic) and add `tests/routing/jev-typesafe-golden.test.ts` comparing the exact serialized request string. Commit it first; it must stay green across wp1/wp2.
+- B3 prospective config. Selector normalization and route preview run against `{ ...config, combos: nextCombos }` in management and against the loaded map in config schema. Tests: same-PUT alias then `<alias>` and synthetic `<alias>--fast` selector referencing self → rejected; changing a referenced combo to `strategy: "jev"` → rejected with the referencing combo named.
+- B4 landing gates. wp4 runs full `bun run test` (resource exception only if documented with focused coverage), both layout guards, file-size ratchet, `tests/lab/core-lab-boundary.test.ts`, and a dispatched **security review** of the final diff (credential forwarding, outbound policy, env keys) recorded in the PR. Every new root-suite test is registered in `scripts/test-layout/layout.json` and `tests/fixtures/test-layout-expected.json`.
+- Notes folded: docs describe cleartext opt-in as loopback **and literal private LAN addresses**; send budget created from the original parent `req` (no thread header forwarded upstream); `POST /api/combos/decision-test` registered as mutating; runtime recursion refusal and fail-open tested independently of save-time validation.

+# 030 wp3: dashboard, i18n, docs
+
+## GUI
+
+- NEW `gui/src/components/combo-workspace-jev-decision.tsx`: `ComboJevDecisionSection` replaces `JevDecisionFields` (moved out of `combo-workspace-controls.tsx`). Radio group: TypeSafe / System One-compatible server / opencodex model. Server: existing provider select (with discovery hints from `/api/combos/decision-discovery`). Model: select over a separate `decisionModels` inventory (enabled routable models; jev combos and the combo itself excluded). Shared timeout input. `Test` button → `POST /api/combos/decision-test` with the draft, shows ok/gate/latency, cancels on selection change. Saved combos show a compact recent summary from `/api/usage?jev=1&comboId=&range=7d` (decisions, applied %, avg latency, per-backend).
+- MODIFY `gui/src/combo-workspace-data.ts`: `ComboItem.decisionModel`; `parseComboList`, `draftEquals`, `toPutBody` (explicit null for the inactive selector), `validateComboDraft` (model required for model method, not self/jev), `jevDecisionSummary` shows the model.
+- MODIFY `gui/src/jev-decision-service.ts`: `jevDecisionModelOptions(...)`, `jevDecisionMethod(item)`.
+- MODIFY detail panel / add modal / ComboWorkspace / Combos page to pass `apiBase`, `decisionModels`, combos.
+- MODIFY `gui/src/components/jev-stats-panel.tsx`: per-backend row.
+- i18n: new keys in `en.ts` and the other nine locales; generalize "decision service" wording where it now covers models.
+- Tests: `gui/tests/jev-decision-fields.test.tsx`, `tests/gui/combo-workspace-jev-decision.test.ts`, `gui/tests/jev-stats-panel.test.tsx`.
+
+## Docs
+
+- `docs-site/src/content/docs/guides/combos.md`: JEV section → "Decision method" with the three backends, model example (`ollama/qwen3:4b`), OpenCode zen as a System One row example, recursion rule, timeout, stats, CLI/API.
+- `docs-site/.../reference/configuration/routing.md` field table: `decisionModel`. CLI reference `--decision-model`.
+- `structure/providers-and-adapters.md` JEV contract, `structure/runtime.md` combo dispatch, management/usage owners for the new routes and backend aggregation; `bun run structure:check`.
+- `skills/ocx` surface regenerate if the capability registry changes.

+
+## Resume plan (2026-10-01, fork session 01a0f655)
+
+State at resume: wp1 and wp2 are committed (`a4dd92baac`, `36c444fb5c`). The wp3 GUI section, data helpers, overview/stats wiring, ten-locale keys, and the combos guide rewrite are present but uncommitted. The maintainer forbids local test suites and typechecks for this lane, so the wp3 accept list moves to hosted CI on the wp4 head; nothing below is run locally.
+
+Remaining wp3 work:
+
+1. `combo-workspace-jev-decision.tsx`: restore the accessibility contract the removed `JevDecisionFields` carried. The System One select gets `aria-describedby` pointing at a `-decision-provider-hint` paragraph (service hint plus base URL) and, when the stored row is unusable, at a `-decision-provider-issue` paragraph. The model input gets its own `-decision-model-hint`. The method hint keeps the TypeSafe default text and the empty-server text.
+2. `gui/tests/jev-decision-fields.test.tsx`: move the four existing cases to the method buttons (System One select lists only server rows; switching to TypeSafe is a method click; an unusable deep link lands on the TypeSafe method with no select), and add a model-method case: pick a route, save sends `decisionModel` with `decisionProvider: null`, the combo itself and JEV combos are absent from the route list.
+3. `tests/gui/combo-workspace-jev-decision.test.ts`: `decisionModel` parse/PUT round trip, provider/model mutual exclusion in `toPutBody`, `invalidDecisionModel` for empty, self, and JEV routes, `jevDecisionMethod`, and `jevDecisionModelOptions` exclusions.
+4. `gui/tests/jev-stats-panel.test.tsx`: a per-backend row renders when the payload carries `backends` and is absent for an older server.
+5. Docs: `reference/cli/agents.md` gains `--decision-model <route|->` and `ocx combo test`; `structure/providers-and-adapters.md` JEV section names the backend seam (`jev-dispatch.ts`, `jev-model-backend.ts`, `jev-decision-contract.ts`, `server/responses/jev-model-invoke.ts`), the recursion refusal, the decision-test/discovery routes, and replaces the "no JEV-only editor" sentence with the Decision method section.
+6. Commit wp3 in two commits (GUI + tests, docs + structure) on `codex/jev-decision-routing`.
+
+Verification moves to wp4: exact-head hosted CI (GUI tests, lint, i18n, build, structure:check, privacy scan, full suite shards).
+
+### Audit round 1 amendments (VERDICT: FAIL → plan amended)
+
+7. `tests/gui/combo-workspace-jev-decision.test.ts` summary assertions (`jevDecisionSummary` exact objects) gain `model: null`, plus a model-backed summary case.
+8. `JEV_BACKEND_LABEL_KEYS` moves out of the TSX component into `gui/src/jev-decision-service.ts` (oxlint `only-export-components` rejects a non-primitive constant export beside a component); the component and `jev-stats-panel.tsx` import it from there.
+9. `jevDecisionModelForbidden` strips trailing synthetic selectors before comparing, mirroring `normalizeDecisionModelSelector`: one trailing `--fast` and one trailing `--<effort>` (`none|minimal|low|medium|high|xhigh|max|ultra`), in either order. The server stays authoritative; the GUI check only prevents an obviously refused save. Regression cases cover `combo/self--fast` and a JEV alias with `--high`.
+10. `reference/configuration/routing.md`: add the `decisionModel` row (mutually exclusive with `decisionProvider`, recursion refusal), reword the credential sentence so only the TypeSafe method needs the `jev` key, and repoint the link to `/guides/combos/#decision-method`.
+11. Scope change, recorded: the section ships without discovery hints and without its own recent summary. Recent statistics, including the new per-backend table, stay in the detail panel's Stats tab (`JevStatsPanel`), and discovery stays an API/CLI surface (`GET /api/combos/decision-discovery`). Neither is required by the maintainer brief; both can follow as a GUI-only change.
+
+### Audit round 2 amendment
+
+9 (revised). Exact selectors win first, as on the server (`fast-row.ts` known-id guard, `effort-row.ts`): when the route equals some combo's `combo/<id>`, alias, or model exactly, only that combo decides (refused if it is the edited combo or a JEV combo) and nothing is stripped. Otherwise strip exactly one trailing synthetic marker, either `--fast` or `--<effort>`, never both (the server refuses composed Fast+effort selectors), and re-check. Regression cases: a non-JEV combo literally named `self--fast` stays allowed while `self` is JEV; `combo/self--fast` and `<jev-alias>--high` are refused; `combo/x--fast--high` is not stripped twice.
+
+### Audit round 3 amendment
+
+9 (final). The GUI check is conservative: it may only refuse what the server certainly refuses. A route is never stripped when it exactly equals any known selector, meaning any combo's `combo/<id>`, alias, or model, or any catalog route the section receives (physical model ids, namespaced ids, and model aliases as listed by `/api/models`). Only an unknown route ending in exactly one synthetic marker is stripped once and re-checked against combos. Regression cases add a catalog model literally named `router--high` that stays allowed while `router` is a JEV alias. Anything the GUI cannot decide is left to the server's save-time `decisionModelRouteError`, whose message the dashboard already surfaces.
+
+### Audit round 4 amendment
+
+9 (final, simplified). The GUI does no suffix stripping at all. It refuses only an exact match: the route equals the edited combo's `combo/<id>`, alias, or model, or the same of any JEV combo. Every suffixed or otherwise uncertain selector is left to the server's save-time `decisionModelRouteError`, which knows whether Fast and effort parsing are active, and the dashboard surfaces that error on save. The GUI can therefore never refuse more than the server. Regression cases: exact self and exact JEV alias are refused in the GUI; `combo/self--fast`, `router--high` (with `router` a JEV alias), and a catalog model named `router--high` all pass the GUI check.

The same applies when `Authorization`, `x-api-key`, or `x-goog-api-key` headers override credentials; search-only and MCP-only windows are excluded.

+With the default method, OpenCodex sends one bounded decision request to the fixed
 `https://api.typesafe.ai/v1/systemone` endpoint with model `jev-latest`. Only currently eligible
 configured targets are offered. JEV chooses the target and effort together; the effort is still
 constrained by that target's advertised ladder. JEV is not asked again if the selected target has a
 retryable failure—the existing Combo cooldown and fallback loop continues through the remaining
 configured targets.
 
+#### System One-compatible server
+
+A JEV Combo can ask a hosted or self-hosted server that implements the System One wire contract.
+For example, an Ollama server with System One support can serve `tev1` at
+`POST /v1/systemone` without an API key. Add a provider row with
+`adapter: "jev-decision"` whose `baseUrl` is the **full** decision endpoint, then name it in the
+Combo's `decisionProvider`:
+
+```json
+{
+  "providers": {
+    "ollama-tev1": {
+      "adapter": "jev-decision",
+      "baseUrl": "http://127.0.0.1:11434/v1/systemone",
+      "allowPrivateNetwork": true,
+      "defaultModel": "tev1:4b",
+      "liveModels": false
+    }
+  },
+  "combos": {
+    "jev-local": {
+      "strategy": "jev",
+      "decisionProvider": "ollama-tev1",
+      "decisionTimeoutMs": 60000,
+      "reasoningEffortMode": "adaptive",
+      "targets": [
+        { "provider": "openai", "model": "gpt-6-astra" },
+        { "provider": "openai", "model": "gpt-5.6-sol" },
+        { "provider": "openai", "model": "gpt-5.6-luna" }
+      ]
+    }
+  }
+}
+```
+
+- The row's `baseUrl` must be the full decision endpoint and its path must end in `/systemone`.
+  The decision model is `defaultModel`, else the first `models` entry; a row with neither is
+  treated as unusable and fails open without a request (`jev-latest` is TypeSafe's model and is
+  never sent to a self-hosted host). The row is a decision service only: it is never published as a
+  routable model and cannot be a Combo target.
+- A loopback or LAN endpoint needs `allowPrivateNetwork: true` set explicitly on that row. Use a
+  literal loopback, RFC 1918, or IPv6 ULA address for plain `http:`; every resolved address must stay
+  in the allowed set and no outbound proxy may apply (add the
+  host to `NO_PROXY`). Every other destination must use HTTPS. Redirects still fail open.
+- Only the row's own `apiKey` is sent, and only when it is set; a keyless row sends no
+  `Authorization` header. A row whose `apiKey` references `${TYPESAFE_API_KEY}`/`${JEV_API_KEY}` or
+  another provider's keychain entry is refused as unusable, so `TYPESAFE_API_KEY`, `JEV_API_KEY`, and
+  the `jev` row's key are never sent to a self-hosted endpoint. The `jev` id itself (explicit or
+  omitted) always means the TypeSafe endpoint with model `jev-latest`.
+- Self-hosted services receive each target/effort option as a plain description string (for
+  example `Target openai/gpt-5.6-sol (provider openai, model gpt-5.6-sol) with low reasoning
+  effort.`), because Ollama accepts only string or `null` option descriptions. TypeSafe keeps
+  receiving the structured option objects.
+- OpenCodex offers 2–26 options to a System One-compatible row. Each target contributes one option
+  per offered reasoning effort; use per-target `reasoningEfforts` to trim them. Fewer than 2 or
+  more than 26 options fail open without a request.
+- A cold model load can take tens of seconds, and an aborted decision request makes Ollama abandon the
+  load. Pre-warm the model and keep it resident (`OLLAMA_KEEP_ALIVE=-1`, or `keep_alive`), and raise
+  `decisionTimeoutMs` (1000–120000 ms, default 4000) when the service is slower than four seconds.
+  Every timeout or error still fails open to the first eligible target.
+
+The provider's **Test connection** sends a bounded probe decision to its endpoint.
+**Create JEV Auto** on a System One provider (keyless rows included) prefills that row as the
+decision provider. Disabled rows, endpoints not ending in `/systemone`, and rows without a model
+are shown with a reason and cannot be picked.
+
+[Laya MLX](https://github.com/mizorewww/laya-mlx) runs typed decisions on Apple Silicon. To use it
+with this method, expose it through a System One-compatible HTTP wrapper, then configure a row like
+`ollama-tev1` above with the wrapper's full `/systemone` URL and accepted model id as `defaultModel`.
+The MLX Python runtime alone is not an HTTP decision endpoint. For a loopback HTTP wrapper, keep
+`allowPrivateNetwork: true` and use its literal loopback address.
+
+For a hosted example, a contributor reported the following Zen System One endpoint working in
+[#6185](https://github.com/lidge-jun/opencodex/pull/6185). Configure it manually as an ordinary row;
+this is not an OpenCodex registry preset or a guarantee of current availability:
+
+```json
+{
+  "providers": {
+    "zen-decision": {
+      "adapter": "jev-decision",
+      "baseUrl": "https://opencode.ai/zen/v1/systemone",
+      "defaultModel": "jev-1.13-free",
+      "apiKey": "${ZEN_DECISION_API_KEY}",
+      "liveModels": false
+    }
+  },
+  "combos": {
+    "jev-zen": {
+      "strategy": "jev",
+      "decisionProvider": "zen-decision",
+      "targets": [
+        { "provider": "openai", "model": "gpt-6-astra" },
+        { "provider": "openai", "model": "gpt-5.6-luna" }
+      ]
+    }
+  }
+}
+```
+
+Use that endpoint's own key if authentication is required; omit `apiKey` only if the endpoint
+accepts keyless calls. Never reuse `TYPESAFE_API_KEY` or `JEV_API_KEY` for it.
+
+#### opencodex model
+
+An ordinary chat or Responses model can make the same routing choice without implementing
+`/systemone`. Configure its inference provider as usual and set `decisionModel` to its route:
+
+```json
+{
+  "combos": {
+    "jev-chat": {
+      "strategy": "jev",
+      "decisionModel": "ollama/qwen3:4b",
+      "decisionTimeoutMs": 60000,
+      "targets": [
+        { "provider": "openai", "model": "gpt-6-astra" },
+        { "provider": "openai", "model": "gpt-5.6-luna" }
+      ]
+    }
+  }
+}
+```
+
+Other examples are `deepseek/deepseek-v4-flash`, `openai/gpt-5.6-luna`, or
+`opencode-zen/<model>` for a configured Zen inference model. These are ordinary route strings,
+not decision-service presets; the provider and model must be available on your installation.
+For `openai/gpt-5.6-luna`, configure credentials the internal call can use, such as a stored Codex
+pool login. A caller-owned ChatGPT forward login is insufficient.
+
+The model receives fixed router instructions and one JSON prompt:
+
+```json
+{
+  "state": { "user_task": "Review the requested change" },
+  "options": { "<key>": "Target description and allowed reasoning effort" }
+}
+```
+
+`state` is the bounded evidence described below; `options` maps generated option keys to plain
+descriptions. The reply contract is `{"choice":"<key>"}`, naming exactly one offered option.
+The instructions treat state as evidence, prefer lower resource use among adequate options, and
+require JSON only. An invalid or unlisted choice, malformed response, or failed call fails open.
+
+The internal decision turn carries **no caller credential**, caller headers, tools, session, or
+conversation history. It must use credentials stored for the selected provider, or a genuinely
+keyless local provider such as Ollama. Caller-auth-only configurations, such as Cursor without a
+stored credential or a caller-owned ChatGPT forward login, cannot serve as decision models and
+fail open. Selecting a route is not proof that its credential is usable; test it before relying on it.
+
+A non-JEV Combo can be used as `decisionModel`, but the decision route cannot name this Combo or
+any Combo with `strategy: "jev"`. This applies to canonical `combo/<id>` selectors and aliases,
+including selectors with effort or Fast variants. Save-time validation rejects recursion and the
+runtime also blocks JEV reentry defensively. The decision turn has its own send budget and turn
+lease; it is not logged as a separate request, and reported decision usage belongs to the parent
+request's `jevDecision`.
+
+#### Shared limits, state, and statistics
+
+`decisionTimeoutMs` applies to all three methods: an integer from 1000 to 120000 ms, default 4000.
+Requests and responses are bounded to 64 KiB. The candidate list is bounded to 64 targets; the
+model method also caps target/effort options at 64, response text at 4096 characters, and the
+decision turn's output at 1024 tokens. The
+System One row's 2–26 option limit applies as described above. A timeout or limit failure uses the
+first currently eligible target; it never expands the allowlist or retries the decision.

+### Self-hosted decision model (e.g. Ollama tev1)
+
+`decisionProvider` can point a JEV Combo at a self-hosted Jev-API-compatible decision model such as
+Ollama's `tev1` (Ollama 0.35+, `POST /v1/systemone`, no API key):
+
+```json
+{
+  "providers": {
+    "ollama-tev1": {
+      "adapter": "jev-decision",
+      "baseUrl": "http://127.0.0.1:11434/v1/systemone",
+      "allowPrivateNetwork": true,
+      "defaultModel": "tev1:4b",
+      "liveModels": false
+    }
+  },
+  "combos": {
+    "jev-local": {
+      "strategy": "jev",
+      "decisionProvider": "ollama-tev1",
+      "decisionTimeoutMs": 60000,
+      "targets": [
+        { "provider": "openai", "model": "gpt-5.6-sol" },
+        { "provider": "openai", "model": "gpt-5.6-luna" }
+      ]
+    }
+  }
+}
+```
+
+The row's `baseUrl` is the full decision endpoint and must end in `/systemone`; its model is
+`defaultModel`, else `models[0]` (a row with neither fails open without a request). Loopback needs
+the row's own explicit `allowPrivateNetwork: true`, and plain `http:` is accepted only for `localhost`
+or a loopback/RFC 1918/ULA address literal reached without a proxy. Only the row's own `apiKey` is
+sent — none when it is unset — and a key referencing the TypeSafe environment variables or another
+provider's keychain entry is refused, so TypeSafe credentials never reach it. Options are sent as
+description strings, which Ollama requires. `tev1` was trained on 2–24 options, so keep target ×
+effort pairs at 24 or fewer (fewer than 2 or more than 26 fail open without a request);
+its effective context is about 2k tokens and OpenCodex clips the task text to 500 characters. Keep the
+model resident (`OLLAMA_KEEP_ALIVE=-1`) and raise `decisionTimeoutMs` for slow services; see
+[System One-compatible server](/guides/combos/#system-one-compatible-server).
+In the dashboard, choose **System One-compatible server** in the JEV Combo's **Decision method**
+section under **Models → Combos**, then pick the row and set **Decision timeout (ms)**.

 | Codex accounts | Account pool cards, add-account flow, switch and reset modals (`gui/src/components/CodexAccountPool.tsx`, `gui/src/components/AddCodexAccountModal.tsx`), plus the generic account-targeting picker opt-in on `gui/src/pages/codex-set-multiauth.tsx`. Add/delete/login completion is projected to one boolean before presentation; pending catalog work is a warning, not a failed account mutation. The main card's native-main device reauth (#3898) is owned by `gui/src/components/use-main-device-reauth.ts`: the dedicated `/api/codex-auth/main/reauth-device` namespace only — never the pool login route — with flowId-owned polling, an allowlisted verification URL, and no token fields accepted from payloads. The main-device reauth hook retains flow ownership from the Cancel click, while DELETE is unresolved and after retryable failure; polling normally continues. A concurrent GET HTTP error cannot expose a replacement login POST before DELETE settles. If a retryable DELETE failure races with a non-2xx GET while the flow is pending or committing, either response order preserves same-flow Cancel retry, restores the last server-provided device code, verification URL, and phase when needed, and keeps the existing poll cadence so a later terminal result remains observable. Outside same-flow cancellation ownership, a GET HTTP failure still stops polling without starting a second login POST. The cancellation-failure indication survives pending status updates until a trusted terminal result releases ownership. A successful DELETE with a terminal `failed` DTO releases it and uses the same closed failure-code mapping as polling; only `succeeded` notifies login completion. Unrecognized or nonterminal DTO status values remain retryable. A DELETE response with HTTP 404 and code `unknown_flow` releases the expired flow and shows the existing generic failure state so device re-login is available again; it claims neither login success nor confirmed cancellation. Confirmed cancellation also makes device re-login available. Start, polling and cancellation completions verify their controller or flow ownership after asynchronous response reads; replaced flows and unmounted hooks cannot update a newer flow or notify completion. Effect setup restores mounted state after the StrictMode development cleanup cycle. |

+# JEV Decision Routing
+
+This document owns the JEV Combo decision contract: the canonical TypeSafe preset, self-hosted
+System One rows, the decision backends, the request-path integration, the dashboard surfaces,
+and the content-free statistics projection. Provider and adapter selection in general stays in
+[Providers And Adapters](../providers-and-adapters.md).
+
+`src/providers/registry/entries-extended.ts` owns the canonical `jev` key preset at
+`https://api.typesafe.ai/v1/systemone` with adapter `jev-decision`. It is a credential owner, not an
+inference route: the registry marks it `credentialOnly`, its adapter is deliberately absent from the

+key login returns unknown without probing a nonexistent model catalog. The normal `ocx login jev`
+flow and provider-workspace API-key panel both persist the same credential-only row. Combo validation
+rejects every `jev-decision` row as a target; `src/codex/catalog/gather-capture.ts` never gathers one.
+`src/server/management/provider-routes.ts` tests those rows through `probeJevDecisionProvider`
+(no user prompt, sanitized status); a retargeted `jev` row reports not-applicable and sends nothing.
+
+The request path consumes a configured literal/reference key only when the row still matches the
+canonical registry transport, with `TYPESAFE_API_KEY` and the standard provider-derived
+`JEV_API_KEY` as explicit environment fallbacks. A same-named custom destination cannot receive
+either credential through the JEV client; a retargeted `jev` row is ignored, never a custom
+destination. Automated coverage mocks TypeSafe; live-key behavior is an operator smoke boundary. A Combo's `decisionProvider` selects the service: omitted or `"jev"` (stored as omission) is that
+canonical path with `jev-latest`; any other id must be an enabled `jev-decision` row with a full
+`/systemone` `baseUrl` and a `defaultModel`/`models[0]`, sending only its own `apiKey` (a TypeSafe
+env reference or foreign keychain entry makes it unusable). `allowLocalCleartextPost` in
+`src/lib/provider-outbound.ts` admits `http:` only with the row's explicit `allowPrivateNetwork`, a
+`localhost`/loopback/RFC 1918/ULA host whose answers stay in that set, and no proxy. Options go out as
+strings (Ollama requires them); under 2 or over 26 fail open locally (`no_choices`/`invalid`), unusable
+rows reuse `missing_key`, and `decisionTimeoutMs` (1000..120000) replaces the 4 s default.
+
+Decision backends. `src/combos/jev-dispatch.ts` derives the backend from the Combo and never stores
+it: `decisionModel` set means `model`, a `decisionProvider` other than `jev` means `systemone`, and
+neither means `typesafe`; setting both is a config error. The System One path is `src/combos/jev.ts`
+unchanged, so the TypeSafe request bytes stay pinned by `tests/fixtures/jev-typesafe-request-golden.json`.
+`src/combos/jev-model-backend.ts` asks an ordinary opencodex route for `{"choice":"<key>"}` over the
+same bounded state and option map, under the same deadline, bounds, and fail-open gates;
+`src/combos/jev-decision-contract.ts` holds the constants the GUI shares. The server glue
+`src/server/responses/jev-model-invoke.ts` runs that choice as a fresh internal `/v1/responses` turn
+with `tools: []`, its own send budget and turn lease, the parent's admission scope only, explicit null
+caller credentials, no caller headers or history, a 1024-token `max_output_tokens` ceiling that
+also sizes the spend reservation, and a 64 KiB bounded response; it is flagged
+`internalDecisionCall`, which `src/server/responses/request-prepare.ts` uses to keep caller-scoped
+memory and shadow-call rewrites off the decision turn and to refuse JEV Combo reentry. Save-time
+recursion and route checks live in
+`src/server/management/decision-model-validation.ts` (a decision model may not resolve, after Fast
+or effort selector normalization, to its own Combo, any JEV Combo, or a `jev-decision` row; a provider
+PATCH cannot turn a referenced row into one). `src/server/management/decision-routes.ts` serves
+`POST /api/combos/decision-test`, one synthetic two-option probe of a saved or unsaved method (the
+body's `decisionProvider` / `decisionModel` select the method, none means TypeSafe; `comboId` only
+scopes the recursion rules, and a disabled, model-less or non-System-One row is refused by name), and
+`GET /api/combos/decision-discovery`, read-only System One and catalog hints built by
+`src/server/management/decision-discovery.ts`. Persisted decisions carry an optional `backend`, and
+the usage aggregate reports per-backend counts and latency with older rows as `unknown`.
+
+`src/combos/jev.ts` extracts bounded user-task, previous-assistant, and latest-tool-output text plus
+the tool name and boolean signals; raw image data, tool arguments, encrypted reasoning, headers, and
+the JEV credential are excluded. It owns the joint target/effort choice map, strict response
+validation, canonical `jev-latest` destination, default four-second deadline, no-redirect policy, bounded response,
+and caller-cancellation propagation. Missing credentials or safe state, transport failures, and invalid

Subject: [PATCH 38/61] fix(chatgpt): close the #6361 review follow-ups (#6412)

Follow-up to #6361. The app-server shim filter now passes a complete line over the 8 MiB cap through as it arrived, even when the whole line lands in one chunk, so it is never joined or parsed. The guide and structure doc now state when the shim falls back to the original binary, what restore does when ChatGPT is not installed, and only behavior that has been verified. The manifest maps src/cli/ and src/codex/ for this doc.

-A failed precondition or a failed self-test runs the original binary with untouched stdout.
+When the platform is not macOS, the OpenCodex runtime is missing, or the filter
+self-test fails, the launcher runs the original binary with untouched stdout. A
+missing bundled app-server binary is the exception: there is nothing to fall back
+to, so the launcher exits with an error (see below).
 A filter that passes the self-test and then dies mid-session closes the pipe.

+What the bundled app-server does after that has not been verified; it may get
+SIGPIPE or a write error and be respawned by Desktop through the same launcher.
 The filter's passthrough mode limits this to an exit/crash case: a rewrite exception
 passes its line through, and an unexpected rewrite-machinery failure switches the
 remaining stream to raw bytes.

Build the bundled ChatGPT app-server candidate with posix.join on every host. A macOS bundle path is POSIX, and host join produced backslash candidates on Windows, which failed windows 3/9 of the dev Cross-platform run.

 rules on every host (#6414)

On every host, classify synced-state paths with POSIX path operations. Only macOS runs this detection, but the darwin-injected tests use POSIX fixtures, and on Windows CI the host path module produced backslashes and drive letters, so five classification cases failed (dev CI windows 5/9 after #6398).

Subject: [PATCH 41/61] feat(codex): window-aware main-account hard-lock
 thresholds and outside-usage warning (#6363)

Raises the main-account hard lock from one 98% rule to window-aware thresholds: by default 90% for the 5-hour window and 98% for the weekly window, configurable from 80 to 100. When usage rises with no opencodex activity, the dashboard and ocx status show a warning about outside usage. Activity is counted only for admitted requests, so repeated refusals cannot hide that rise. The settings route validates both thresholds, the GUI guards the server values, and the projection behind ocx status is covered by tests.

Refs #6196, #4878.

+# Quota send-lock contributor split: roadmap
+
+Status: roadmap locked by the docs-only cycle; implementation runs one PABCD cycle per PR.
+Date: 2026-10-01. Baseline: `origin/dev` `64294638a69e25ca0c7a4e2102e2349973161f71`.
+
+## Problem
+
+The Codex desktop composer disables Send when the signed-in ChatGPT quota reports
+exhausted, even for models opencodex routes to independently funded providers
+([#6196](https://github.com/lidge-jun/opencodex/issues/6196), duplicate
+[#4878](https://github.com/lidge-jun/opencodex/issues/4878)). Two contributor PRs
+address it:
+
+- [#5947](https://github.com/lidge-jun/opencodex/pull/5947) (lcxhh521, head
+  `61947c04d9`, +7317 / 54 files) mixes three mechanisms: (a) a local-CA TLS
+  intercept of chatgpt.com traffic (send-unblock), (b) a PAC fallback entry so the
+  intercept survives opencodex stopping, (c) an app-server shim: a `CODEX_CLI_PATH`
+  launcher that execs the bundled `codex app-server` and filters only its stdout,
+  clearing the plain-quota gate in `account/rateLimits/read` and
+  `account/rateLimits/updated`.
+- [#5879](https://github.com/lidge-jun/opencodex/pull/5879) (MateuszJuszczyk, head
+  `9a5b6d9d72`) toggles `codexDesktopAuthless` automatically on quota exhaustion.
+
+## Evidence
+
+- #6196 (TooSpace, 2026-09-27..29): with (a)+(b) deployed, the loopback listener saw
+  **zero established connections over ~20 h**; the bundled app-server owns the
+  chatgpt.com sockets, so the intercept never sees the gate reads.
+- #6196 (TooSpace, 2026-10-01 10:47 Asia/Taipei): Plus account, 5-hour window 100%,
+  weekly 51%, Desktop 26.928.21956 / bundled CLI 0.159.2: launching through the shim
+  launcher re-enabled Send before the window reset; `dynamic_app_tools_peer_rejected`
+  did not recur. Ingwannu's note: the run had intercept + shim + restart together,
+  so it does not isolate the shim as sole cause.
+- `devlog/_plan/260928_macos_quota_gate/000_design.md` (maintainer design) prefers
+  upstream provider-aware admission and rejects CA installation and quota rewriting.
+  The split PRs below are explicitly experimental/opt-in candidates the maintainers
+  may close against that decision.
+
+## Existing defence and its gaps
+
+`codexMainAccountHardLock` (default on since #5694, `src/codex/main-account-hard-lock.ts`)
+stops opencodex from sending main-account traffic at 98% on any governing window.
+Gaps: usage outside opencodex, observation lag (a long turn crosses 98%), the small
+Plus 5-hour window, and `unknown` state admitting.
+
+## PR map (dependency order)
+
+| Doc | Work-phase | Branch | Base | Credit |
+| --- | --- | --- | --- | --- |
+| 010 | wp1 hard-lock hardening | `codex/main-hard-lock-window-thresholds` | `dev` | none (maintainer code) |
+| 020 | wp2 app-server shim | `codex/chatgpt-app-server-shim` | `dev` | Co-authored-by: lcxhh521 |
+| 030 | wp3 local-CA send-unblock intercept | `codex/chatgpt-send-unblock-intercept` | wp2 branch (stacked) | Co-authored-by: lcxhh521 |
+| 040 | wp4 PAC fallback | `codex/chatgpt-pac-fallback` | wp3 branch (stacked) | Co-authored-by: lcxhh521 |
+| 050 | wp5 #5879 disposition | none (rationale only) | - | - |
+| 060 | wp6 closeout | - | - | - |
+
+Stacking reason: wp2, wp3 and wp4 all extend the same new `ocx chatgpt` command and
+`chatgptDesktop` config block. Opening them independently against `dev` would
+make the second one to land conflict on `src/cli/chatgpt-command.ts`, the config
+type/validator, the CLI registry, the guide and `structure/clients/chatgpt-desktop.md`.
+The PAC fallback has no function without the TLS listener (its CONNECT entry only
+splices into that listener), so wp4 cannot target `dev` alone. The shim has no
+dependency on either and is the piece with field evidence, so it sits at the bottom.
+Stack lifecycle:
+
+- Parent merged (squash): rebase the child with
+  `git rebase --onto origin/dev <old parent head> <child>`, retarget it to `dev`, and
+  wait for fresh CI on the new head. Cascade the same rebase to every descendant
+  (wp4 onto the new wp3 head) and wait for fresh CI on each. Land bottom-up only.
+- Parent closed: its children carry its commits and dependencies, so they close with
+  it unless a maintainer asks for a reconstruction on a different base. The children
+  are themselves "may close" candidates, so this is the expected path if the shim is
+  rejected.
+
+wp1 is independent of all three.
+
+## Common constraints
+
+- New branches from latest `origin/dev`; `codex/` prefix; no git config, no GIT_* env.
+- Respect `tests/fixtures/file-size-baseline.json`; unlisted files stay below 2000 lines.
+- New test files: register in `scripts/test-layout/layout.json` `explicit` and
+  `tests/fixtures/test-layout-expected.json`.
+- `src/router.ts`, `src/server/lifecycle.ts`, `src/server/responses/core.ts` must not
+  reach new optional modules (core-lab boundary).
+- GUI strings in all ten locale catalogs; GUI PRs need a screenshot on `pr-assets`.
+- Verification per PR: `bun run typecheck`, focused tests, `bun run test:changed`,
+  `bun run structure:check`, `bun run privacy:scan`, `bun run skill:surface:check` when
+  the CLI changes, the core-lab boundary test, and the full `bun run test` (or the

+# 010 — wp1: window-aware hard-lock thresholds and outside-usage warning
+
+Branch `codex/main-hard-lock-window-thresholds` from `origin/dev`. Maintainer code.
+
+## Behaviour
+
+1. The 5-hour (short) window locks at a lower percentage than the weekly/monthly
+   (long) windows. Defaults: short **90**, long **98** (unchanged). Both configurable.
+2. When the main account's usage rises while opencodex has not used the main
+   account, the dashboard and `ocx status` show a warning: usage is being consumed
+   outside opencodex, so the lock may not prevent exhaustion.
+
+## Config (NEW key)
+
+`src/types/config.ts` next to `codexMainAccountHardLock`:
+
+```ts
+/** Per-window lock thresholds in percent (#6196). short: 5h window, default 90; long: weekly/monthly, default 98. */
+codexMainAccountHardLockThresholds?: { short?: number; long?: number };
+```
+
+`src/config/schema/config-schema.ts`: object of two optional integers in
+`[MAIN_ACCOUNT_HARD_LOCK_MIN_PERCENT, 100]`, `.catch(undefined)` per field so a
+malformed disk value degrades to defaults (same pattern as the boolean at :188).
+
+`PUT /api/settings` (`src/server/management/config-routes.ts`): accept the object,
+reject non-integer/out-of-range values and `short > long` with 400 before any write,
+include it in the rollback snapshot; GET returns the effective thresholds in the
+existing hard-lock projection.
+
+## Constants (MODIFY `src/codex/quota-types.ts`)
+
+```ts
+export const MAIN_ACCOUNT_HARD_LOCK_PERCENT = 98;               // long default, unchanged export
+export const MAIN_ACCOUNT_HARD_LOCK_SHORT_PERCENT = 90;          // NEW short default
+export const MAIN_ACCOUNT_HARD_LOCK_MIN_PERCENT = 80;            // NEW lowest configurable value
+```
+
+## Lock (MODIFY `src/codex/main-account-hard-lock.ts`)
+
+- NEW `resolveMainAccountHardLockThresholds(config): { short: number; long: number }`
+  — defaults above, clamps invalid in-memory values back to defaults, forces
+  `short <= long`.
+- `WindowReading` gains `kind: "short" | "long"`; `governingWindows()` tags the 5h
+  reading short, weekly and monthly-only long.
+- `getMainAccountHardLockStatus()` compares each window with its own threshold and
+  returns `thresholds` plus `window: "short" | "long"` of the first blocking reading.
+- `PolicyConfig` adds `codexMainAccountHardLockThresholds`.
+
+## Evidence retention (MODIFY `src/codex/quota.ts`)
+
+The three policy-evidence retention guards (`assignCarriedShort` ~:263,
+`preserveKnownWeekly` ~:374, `preserveKnownShort` ~:407) compare against 98. With a
+configurable threshold a reading between the threshold and 98 could be dropped by an
+elapsed reset or partial update and silently unlock. Change the comparison to
+`MAIN_ACCOUNT_HARD_LOCK_MIN_PERCENT` so any reading that can block under some
+allowed configuration is retained until a fresh lower reading arrives. Retaining a
+non-blocking reading only keeps a stale percentage visible; it never blocks.
+
+## Error copy (MODIFY `src/codex/auth-context.ts` ~:517)
+
+`CodexMainAccountHardLockError` message stops naming 98: "Codex main account is
+blocked by the main-account quota policy (5h ≥ X%, weekly ≥ Y%)." The constructor
+takes the thresholds from the status. Update tests that assert the old string.
+
+## Outside-usage detector (NEW `src/codex/main-account-external-usage.ts`)
+
+Process-local, no persistence, no timers. It keeps its own baseline of fresh readings
+and never reads the merged policy snapshot, which can contain carried windows.
+
+```ts
+export const EXTERNAL_USAGE_QUIET_MS = 30 * 60_000;
+export const EXTERNAL_USAGE_TTL_MS = 6 * 60 * 60_000;
+type FreshWindow = { kind: "short" | "long"; percent: number; resetAtMs: number };
+export function noteMainAccountActivity(now = Date.now()): void;
+/** Only windows with a validated percent AND a known reset in this observation. */
+export function observeMainAccountUsage(identityKey: string, windows: FreshWindow[], now = Date.now()): void;
+export function forgetMainAccountUsage(): void;
+export function getMainAccountExternalUsageWarning(identityKey: string | undefined, now = Date.now()):
+  { window: "short" | "long"; fromPercent: number; toPercent: number; observedAt: number } | undefined;
+export function resetMainAccountExternalUsageForTests(): void;
+```
+
+Rule: the module holds `{ identityKey, perWindow: { percent, resetAtMs, observedAt } }`.
+A new `identityKey` replaces the baseline and drops any warning. For a fresh window
+with the same kind and the same normalized `resetAtMs` (both known; a missing reset
+never proves the same episode), a rise of at least 1 point with no main-account
+activity noted since `baseline.observedAt - EXTERNAL_USAGE_QUIET_MS` records a warning.
+A changed reset rebaselines that window and clears its warning. Warnings expire after
+`EXTERNAL_USAGE_TTL_MS` or once the recorded `resetAtMs` passes, whichever is first; the getter returns nothing for a different identity.
+Over-counting activity only suppresses warnings. A single turn longer than the quiet
+margin can still cause a false positive, so the copy says "possible usage outside
+opencodex".
+
+Hooks:
+
+- `src/codex/auth-context.ts` `assertMainAccountPolicy()` (:703) runs on every
+  main-credential attach (main-pool, substituted main, caller bearer matching observed
+  main) and on some admission checks before refusal. Call `noteMainAccountActivity()`
+  there before the `!config` early return; the extra calls only suppress warnings.
+- `src/codex/quota.ts` `setAccountQuotaFromParsed()` (~:318): when `isMain`,
+  `mainWriter` is present and `policyQuota` (this call's validated observation) is
+  non-null and carries usage, build `FreshWindow`s from `policyQuota` only (short:
+  `shortPercent` + `shortResetAt`; long: `weeklyPercent` + `weeklyResetAt`, or monthly
+  when `monthlyIsPrimaryWindow`), normalize with `resetAtToMs`, and call
+  `observeMainAccountUsage(mainWriter.identityKey, windows)`.
+- `clearAccountQuota()` (main or all) calls `forgetMainAccountUsage()`.
+- Readers pass `getObservedMainQuotaIdentityKey()` to the getter.
+
+## Surfaces
+
+- `src/codex/auth-api/account-list.ts` (~:374): the main-account hard-lock DTO gains
+  `thresholds` and optional `externalUsage`.
+- GUI `gui/src/components/MainAccountHardLockSetting.tsx` and
+  `codex-account-pool-main-card.tsx`: copy uses the effective thresholds; amber notice
+  when `externalUsage` is present. Locale keys in all ten catalogs; replace fixed-98
+  strings (`en.ts:2312-2325`).
+- `ocx status`: `src/oauth/health.ts` `fetchCodexHealthFromLiveProxy()` already reads
+  `/api/codex-auth/accounts`; project the main hard-lock state, thresholds and
+  external-usage warning, and print one line in `src/cli/status-oauth.ts` (human) and
+  include it in JSON. Keep `src/cli/index.ts` (1979 lines) untouched.
+
+## Tests (NEW sibling files; register in both layout files)
+
+- `tests/codex-integration/main-account-hard-lock-thresholds.test.ts`: short 90 blocks
+  at 90 with weekly 30; weekly 95 admits by default and blocks with long 95;
+  configured short/long; invalid config falls back; retention of a 92% short reading
+  across an elapsed reset.
+- `tests/codex-integration/main-account-external-usage.test.ts`: rise without
+  activity warns; activity inside the quiet margin suppresses; reset change clears;
+  identity change clears; expiry.
+- `tests/config/settings-main-account-hard-lock.test.ts` (MODIFY, 119 lines): PUT
+  validation and rollback for thresholds.

+# 020 — wp2: app-server shim (experimental, macOS, default off)
+
+Branch `codex/chatgpt-app-server-shim` from `origin/dev`. Code from #5947 with
+`Co-authored-by: lcxhh521 <lcxhh521@users.noreply.github.com>` (use the author's
+commit email from `git log pr/5947` if public).
+
+## Scope
+
+Only mechanism (c). No listener, CA, PAC, launch watcher, or `unblockSend`.
+
+## Files
+
+NEW `src/chatgpt/app-server-shim/`:
+
+- `gate-rewrite.ts` — pure copy of #5947 `rewrite.ts` `isRecord`, `PLAIN_QUOTA_REACHED_TYPE`,
+  `hasNonQuotaBlock`, `unlockRateLimitGate` (pr/5947 rewrite.ts:40-47, 157-246).
+  No conversation/endpoint/SSE code.
+- `app-server-rewrite.ts` — #5947 file, import from `./gate-rewrite`.
+- `filter.ts` — #5947 `app-server-shim.ts` line filter, without its `import.meta.main`
+  entry. NEW `runChatgptAppServerFilter({ selfTest })`: with `selfTest` it rewrites a
+  built-in fixture line, checks the result and exits 0; otherwise it filters stdin to
+  stdout. If the rewrite machinery throws outside the per-line guard, it switches to
+  raw byte passthrough for the rest of the stream.
+- Entry point: hidden `ocx internal chatgpt-app-server-filter [--self-test]` in
+  `src/cli/internal-command.ts` (hidden commands stay out of the registry and skill
+  surface by design). This works for source installs and compiled standalone builds,
+  because the launcher re-enters the current CLI through `process.execPath` +
+  `selfLaunchArgv()` (`src/lib/self-launch-argv.ts`) instead of pointing Bun at a `.ts`
+  file that a compiled build does not ship.
+- `launcher.ts` — `buildChatgptShimLauncher(argv, real)`, `writeChatgptShimLauncher()`,
+  `chatgptShimLauncherPath()` (adapted from #5947 runtime.ts:123-161). Launcher body:
+
+```bash
+#!/bin/bash
+# opencodex (experimental): ChatGPT app-server stdout passes through the quota-gate filter.
+REAL='<bundled codex>'
+FILTER=('<execPath>' ['<cli entry>'] internal chatgpt-app-server-filter)
+if [ "$(uname -s)" = "Darwin" ] && [ -x "${FILTER[0]}" ] \
+   && "${FILTER[@]}" --self-test >/dev/null 2>&1; then
+  exec "$REAL" "$@" > >(exec "${FILTER[@]}")
+fi
+exec "$REAL" "$@"
+```
+
+  Guarantee, stated exactly: a failed precondition or a failed self-test runs the
+  original binary with untouched stdout. A filter that passes the self-test and then
+  dies mid-session closes the pipe. Expected (not yet validated against the bundled
+  app-server): the server gets SIGPIPE or a write error and Desktop respawns it through
+  the same launcher. The filter's passthrough mode limits this to an exit/crash case.
+
+NEW `src/cli/chatgpt-command.ts` — `ocx chatgpt launch | restore | status` (macOS only;
+other platforms print "macOS only" and exit 1). `launch` refuses unless
+`chatgptDesktop.appServerShim === true`, writes the launcher, quits the app if
+running, and relaunches with `open -a ChatGPT --env CODEX_CLI_PATH=<launcher>`.
+`restore` relaunches without the variable and deletes the launcher. `status` prints
+`app-server shim (experimental): on|off`, launcher presence and whether a running
+app carries the variable. All help text says "experimental".
+
+MODIFY `src/cli/dispatch.ts`, `src/cli/help.ts`, `src/cli/registry.ts`
+plus `src/cli/capabilities.ts` and the regenerated skill surface (`bun run skill:surface`).
+
+Config: `src/types/config.ts` `chatgptDesktop?: { appServerShim?: boolean }`;
+`leaf-validators.ts` strict object, `config-schema.ts` registration with
+`.catch(undefined)`; `src/config/diagnostics.ts` warns when set on non-macOS.
+
+## Tests
+
+NEW `tests/chatgpt-unblock/app-server-shim.test.ts`: gate rewrite cases from #5947
+`unblock-app-server-shim.test.ts` (re-pointed to the new modules), self-test exit code,
+passthrough after an internal rewrite failure.
+NEW `tests/chatgpt-unblock/app-server-shim-launcher.test.ts`: launcher text for source
+argv and compiled argv (`selfLaunchArgv` with `isStandaloneExecutable`); executing the
+generated script on a stub `REAL` with (a) missing runtime, (b) failing self-test →
+stub sees untouched stdout, (c) passing self-test → stub output filtered, (d) passing
+self-test then filter exits → stub terminates instead of hanging (mock behaviour only).
+NEW `tests/chatgpt-unblock/chatgpt-desktop-config.test.ts`: absent/false/malformed → off,
+strict write rejection. CLI registry/capabilities parity via existing tests after
+`bun run skill:surface`. Register new files in both layout files.
+
+## Docs
+
+`docs-site/src/content/docs/guides/chatgpt-desktop.md` (English, marked experimental,
+security notes: generated executable, `CODEX_CLI_PATH`, quota gate fields rewritten
+while displayed usage stays honest), sidebar entry in `astro.config.mjs`;

+`src/chatgpt/`; `structure/INDEX.md` via `bun run structure:index`.

+# 050 — wp5: #5879 auto desktop-authless disposition
+
+Decision: **no carried PR; rationale only.** #5879 is closed with credit after the
+split PRs are up.
+
+Reasons (read-only review against `64294638`):
+
+1. Requirement conflict: #6196's reporter requires the signed-in account to stay in
+   the UI. Authless removes the account plane (usage, Fast, plugin/thread identity),
+   and the 260928 design rejects `requires_openai_auth = false` as the fix.
+2. Disruption: every transition calls `performCodexRestart()`, restarting Desktop and
+   app servers from a background sweep without user consent.
+3. Recovery proof is unsound on today's API: `refreshCodexQuotaForActivation()`
+   returns silently for unavailable leases/reauth/missing credentials and
+   `isCodexQuotaExhausted(null)` is false, so unknown state releases authless.
+4. Persists before injecting, restarts even when injection fails, and the next sweep
+   sees the stored state and never retries; overwrites the manual
+   `codexDesktopAuthless` preference.
+5. Overlap: wp1 lowers the short-window threshold so opencodex traffic leaves the
+   main account earlier, and wp2 addresses the client gate directly without leaving
+   the signed-in mode.
+
+A revised proposal would need authoritative recovery evidence, a separate automatic
+state that never overwrites the manual preference, retry of failed application, and
+deferred restarts.

 | `codexAccountNamespaces?` | `Record<string, string>` | unset | Public selector to Codex account mapping. The main login maps to the config-only sentinel `@main`; added accounts map to their account id. Normally generated by enabling `codexAccountPickerEnabled` rather than hand-authored. An empty map means no account-qualified rows exist, including the Luna Reserve row. |
 | `codexClientCompaction?` | `boolean` | `false` | Opt into Codex client-side compaction on an authenticated loopback bind. Uses the dedicated `opencodex` provider identity with `requires_openai_auth = true`, preventing new routed compactions from storing OpenCodeX-owned `ocx1:` state. `codexDesktopAuthless` takes precedence when both are enabled and keeps `requires_openai_auth = false`. V2 sub-agent routing is unchanged. `ocx system settings --client-compaction on`. See [Codex integration](/guides/codex-integration/#client-side-compaction-opt-in). |
 | `codexProviderDisplayName?` | `string` | `"OpenCodex Proxy"` | Label Codex shows for the injected `opencodex` provider, written as its `name` field in `config.toml` and the reference profile. Presentation only: routing resolves through the provider id `opencodex`, so a rename never moves `model_provider = "opencodex"` or the `[model_providers.opencodex]` header and cannot orphan threads already tagged with that id. Codex refuses to load a provider with no name, so there is no way to omit the field — choose a neutral label instead. A blank, over-128-character, or control-character value is ignored and the default label is written. |

Invalid persisted fields fall back to defaults; the settings API rejects invalid writes before mutation. |
 | `resetCreditAutoRedeem?` | `{ enabled?: boolean; leadTimeMinutes?: number }` | off | Opt-in: redeem the main Codex account's soonest-expiring reset credit `leadTimeMinutes` (1–60, default 10) before it expires. Every attempt re-reads the upstream credit list first and skips when the credit is gone (for example, redeemed by hand); the `redeem_request_id` is journaled in `$OPENCODEX_HOME/reset-credit-auto-redeem.json` before the call so a crash replays the same idempotent request instead of spending a second credit. Servers sharing this configuration directory coordinate reservations and settlements so one process does not replace another's request record. Logs carry a hashed account key only. |

 ## Low-quota protection

Manual resume is respected across every qualifying window already active for that account until recovery or a new reset episode. Native main keeps its separate 98% hard lock. Each server registration owns a bounded status ledger; its authenticated management route exposes only its own account ids. The default alert is a log line plus a `logged` event, with no OS notification. A pool response that could not capture a writer at dispatch (credential already replaced, or the store unreadable) fails closed the same way: its snapshot still refreshes the display cache, but it never authorizes a policy pause. Writer-free legacy and login paths are explicitly distinct from that pool contract and keep their existing observation behavior.

+`codexMainAccountHardLockThresholds` permits ordered integer thresholds from 80 through 100.
+Policy evidence retention uses the minimum configurable 80%, so a partial update or elapsed reset
+cannot erase a reading that may block under an allowed configuration. Fresh lower usage and
+validated window-absence evidence still own recovery.
+
+The outside-usage detector keeps a separate process-local baseline keyed by observed main identity.
+Only validated fresh percentages with a known normalized reset from the current observation enter it;
+carried policy windows, credits-only updates, writer-free observations and retired writers cannot
+create warnings. A rise of at least one point in the same reset episode warns only when no main
+activity was noted since 30 minutes before the preceding reading. Main credential admission notes
+activity only after the policy check admits the request; a hard-lock refusal is not opencodex's own
+use, so repeated refusals cannot hide a rise while the lock holds. Identity replacement drops all warnings; reset
+replacement drops that window's warning. Main/all quota cleanup forgets the baseline. Warnings
+expire at reset or six hours after detection. Main-card/settings DTOs and live CLI projections expose
+only window kind, previous/current percentage and observation time; the notice says possible usage
+outside opencodex because a long-running request can also explain the rise.

Subject: [PATCH 42/61] fix(service): bound every Windows manager command the
 guarded stop depends on (#6403)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Every execFileSync a Windows verdict or stop relies on ran without a timeout:
all schtasks operations via runFile (/query, /end, /delete, /create, /xml),
WinSW verbs including stopwait, and every sc.exe query/qc/stop/delete. A wedged
Task Scheduler or Service Control Manager service would hang the CLI forever
inside a guarded stop — observed natively as the bundled stop blowing the
desktop takeover deadline while sibling probes (PowerShell, wrapper kill) are
already bounded.

Bounds: 15s for SCM round-trips and schtasks operations (all sub-second on a
healthy system, far under the app's startup budget); 40s for WinSW stopwait so
it outlasts the SCM <stoptimeout> (20s) in the generated service definition.
The interactive install /p call stays unbounded by design — it waits on the
operator's password input. A killed command throws into the same unreadable/
failed/unknown classification a nonzero exit would, so no verdict weakens.

Source-level regressions pin the contract: every execFileSync in winsw.ts is
bounded except the inherited-stdio interactive call, stopwait routes to the
longer bound, and runFile carries SCHTASKS_TIMEOUT_MS.

 `ocx resolve` (`src/cli/resolve.ts`) is the machine surface a desktop shell asks instead of resolving the config home, the port, and liveness itself: the home comes from `src/config/paths.ts`, the effective port is the live listener's when the identity-checked `findLiveProxy` answers and the configured `config.port ?? 10100` otherwise, and the liveness verdict is that same module's output (pid, runtime-versus-config provenance, version, role). Config reads go through `readConfigDiagnostics`, not `loadConfig`: a missing file is defaults, but an invalid file exits 1 instead of being repaired to defaults, because a defaulted port is a guess the caller must refuse. Liveness is three-valued: when `findLiveProxy` returns null, resolve re-asks the endpoints with the updater's tri-state probe (`endpointsToProve` + `everyEndpointProvenDown` + `probeProxyLiveness`), and only a unanimous definitive "dead" becomes `absent-proven`; unknown exits 1 and never authorises a start. Discovery borrows `START_OWNERSHIP_LIVENESS`, the start path's ownership budget — the verdict feeds the shell's launch decision, so the cost of a false "nobody listening" is the duplicate proxy (#5004). The verb is in `skipsCodexShimAutoRestore`, so a read-only lookup never triggers a shim repair. Arguments are pre-parsed in `src/cli/root.ts` and exit 64 before any preflight side effect, the same ordering `ocx ready` obeys. `ocx-resolve/1` also reports `ownership` (`none`, `owned`, or `unknown`) and `takeover` (`supported` with protocol version, minimum CLI version and compatibility token, or `blocked` with a reason). A known liveness verdict still exits 0 when ownership is unknown, but takeover is blocked. An unreadable second service-state read blocks takeover instead of becoming an absent registration. `src/service/managing-cli.ts` observes the registered and selected PATH CLIs, including Windows PATHEXT order and file validation, before compatibility is offered.
 
-`ocx stop --json` is a reporting layer over the unchanged stop path. `src/cli/index.ts` threads a `StopRunRecord` through the existing receipt, drain, respawn-verification and restore flow, and `src/cli/stop-report.ts` maps the recorded facts plus the signals that already pick the exit code into one versioned document (`schema: "ocx-stop/1"`). With `--json` the human lines print on stderr and stdout carries only that document; exit codes 0/1/79/80 cross the process boundary unchanged. The desktop's opt-in guarded stop adds exact approved PID, endpoint, home, CLI version and compatibility-token expectations; plain `ocx stop` retains its ordinary behavior. Under the ownership mutation lease, `src/cli/stop-approval.ts` re-resolves them and `src/service/guarded-manager-target.ts` binds any installed manager's process tree to the approved PID before a stop action. A pre-action mismatch returns `approval-changed` without stopping. Immediately before any manager stop or direct PID signal, the CLI rechecks the same manager identity or proven absence; a change also returns `approval-changed`. A non-OpenCodex process replacing the OS job in the remaining instant before the manager command is a residual same-user risk outside the ownership lease. The guarded path stops the bound manager, or the approved PID directly when managers are proven absent, then uses a five-second shared deadline to verify PID exit, port availability and definitive endpoint absence. Only after settlement does a read-only manager probe require launchd `not-loaded` in both domains or systemd `inactive` with `MainPID=0`; the state is checked again before a success summary. Timeout, active or unreadable manager state returns terminal `manager-still-active`, even if the endpoint briefly refuses. Windows managers bind through `src/service/windows-guarded-manager.ts`: a Task Scheduler backend must prove a recognized OpenCodex registration against the bounded current-user SID/name lookup, a running task, and a wrapper ancestor carrying this home's canonical paths; an unreadable current identity leaves the manager unknown; a WinSW backend must prove this installation's binary and SCM service PID ancestry; either marks `childNeedsSeparateStop`, so the approved PID receives its own graceful signal only after a successful manager stop because `schtasks /end` does not reliably cascade to the wrapper's child (#764); a failed or unknown manager stop leaves the child untouched. Post-stop Windows inactivity means the task not running, no surviving wrapper process, and no started WinSW — never mere registration presence. A `wscript.exe`, `cscript.exe` or `cmd.exe` whose command line CIM cannot read makes the state unprovable only when it is tied to the proxy: pre-stop, as an ancestor of the approved PID; post-stop, as the former bound manager process or a descendant of it. Unrelated unreadable shells, which a non-admin query returns for other users' and elevated processes, are not evidence either way. An unprovable Windows manager still blocks guarded takeover. The token checks snapshot consistency, not whether a person approved the desktop prompt. `src/cli/stop-restore.ts` owns the shared Codex/Grok restoration and its history-only, history-deferred, and other failure categories.

Subject: [PATCH 44/61] fix(update): release the Bun updater lease around
 service-manager starts (#5760) (#6407)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(update): release the Bun updater lease around service-manager starts (#5760)

withUpdateOwnershipLease held the mutation lease across 'ocx service
repair' in both the stopped-runtime recovery branch and the post-install
refresh. The manager's 'ocx start' child is not a process descendant and
carries no delegated token, so it died at the acquire deadline; recovery
then fell through to an unmanaged direct start beside a dead supervisor —
the same defect bin/ocx.mjs fixed in 444933411, left unfixed here.

The transaction now exposes release()/reacquire(): the lease is released
immediately before each service-manager-mediated start and re-acquired
before each fallback's ownership re-read, so a claim landing in the
unleased window is vetoed rather than killed unleased (bounded acquire
fails closed). Direct recovery keeps the lease as before.

* fix(update): report a post-install lease that stays claimed instead of re-running recovery

* feat(claude): list opencodex models in the Claude Code CLI first-party /model picker

With claudeCode.cliFirstParty on, a plain `claude` now lists routed models in /model.
The intercept listener merges rows into the CLI's served catalog
(GET /api/organizations/<org>/model_selector/cc, cc surface) and the fallback
/api/claude_cli/bootstrap additional_model_options, only for CLI-classified clients
with CLI first-party on, failing open on any error. Rows use Desktop 3P registry
aliases (the CLI offers only Claude-shaped ids) and only ones the registry decodes;
a shared deduped registry build serves startup and the CLI picker. Claude Code's
cached *-cc.json catalog is dropped when the settings env is written and on every
successful first-party reconcile. CLI requests using a registry alias keep the
Code usage surface instead of being counted as Claude Desktop.

* test(grok): follow the startup registry build into its shared helper

* fix(claude): harden the CLI picker catalog per review

Await the shared registry build before re-checking a persisted snapshot after a
restart, re-check each row against the route it was minted for, stream the
catalog body under the 16 MiB cap instead of buffering it, and stop on-demand
registry retries for 30 s after a failed or empty build.

+# 261002 Claude Code CLI first-party picker — plan (010)
+
+## Problem
+
+With `claudeCode.cliFirstParty` on, the standalone `claude` CLI talks to OpenCodex's intercept
+proxy, but its `/model` picker only lists Anthropic models. Claude Desktop's picker mode already
+injects opencodex routes into Desktop's claude.ai bootstrap catalog; the CLI has no equivalent.
+
+## Evidence (live probe, Claude Code 2.1.287, first-party OAuth, throwaway capture proxy in .tmp/)
+
+- The CLI builds `/model` from `GET https://api.anthropic.com/api/organizations/<org>/model_selector/cc`
+  (`/api/model_selector/cc` for token/api-key auth). Body: `{model_selector_state, model_selector_config:
+  [{id:"cc", models:[…Desktop-shaped rows…]}]}`. User-Agent `claude-cli/<v> (external, cli)`.
+- Debug log: `[servedCatalog] primary: … the served list replaces the compiled picker`.
+- Rows appended to the cc surface appear in `/model` and are selectable when the id is Claude-shaped:
+  `claude-opus-4-8-20260919`, `claude-opus-4-8-p1ab`, `claude-opus-4-8-k3x`, `…[1m]` all worked.
+  `gpt-6-luna`, `ocx-claude-native--gpt-6-sol`, `ocx-claude-xai--grok-4.7` render
+  "Update Claude Code to use this model" (unselectable). So the Desktop-picker `ocx-claude-*` ids cannot
+  be reused; the Desktop 3P registry ids (`activeDesktop3pAlias`) can.
+- The CLI caches the served catalog ~1 h in `<claudeConfigDir>/cache/model-catalog/<org>-<hash>-cc.json`
+  and does not refetch while fresh, so a toggle needs that cache invalidated.
+- When the served catalog flag is off, the CLI falls back to the compiled picker plus
+  `additional_model_options` from `GET /api/claude_cli/bootstrap` (UA `claude-code/<v>`), shape
+  `{model, name, description, disabled_reason?}`.
+
+## Diff-level plan
+
+1. `src/claude/intercept/picker-bootstrap.ts`: `PickerModelEntry.description?`; `injectPickerModels(body, models,
+   explain?, options?: {surfaces?, strip?})` — defaults unchanged for Desktop (`ccd`,`code`); when an entry carries
+   a description it is written after stripping.
+2. New `src/claude/intercept/cli-catalog.ts` (no heavy imports): `cliCatalogKind(method, path)`,
+   `rewriteCliCatalogBody(kind, text, models)` (cc surface via injectPickerModels with surfaces `["cc"]` and extra
+   strip `notice`, `selection_notice`; bootstrap appends `additional_model_options` rows not already present),
+   `rewriteCliCatalogResponse(response, kind, models)` (2xx JSON only, size cap, drops content-length/etag,
+   untouched bytes on any failure), `cliCatalogEligible(kind, userAgent, desired)` (model_selector: client's own
+   intent via interceptRouteFor; bootstrap: `desired.cli` and not a Desktop entrypoint),
+   `invalidateClaudeCodeServedCatalog(claudeDir)` (unlink `*-cc.json` only).
+3. `src/claude/intercept/picker-models.ts`: extract shared candidate/profile rendering; add
+   `buildCliPickerModels(input)`: skip real Anthropic routes, alias = `activeDesktop3pAlias`, keep only when
+   `resolveDesktop3pAlias(alias) === route` (never advertise an id the router cannot decode), 1M marker as in
+   Desktop, name = label, description `opencodex · <route>`. `createPickerModelSnapshot(load, path, build?)` and the
+   persisted-snapshot parser accept the optional description.
+4. `src/claude/intercept/listener.ts`: optional `cliCatalog(req, kind)` hook; for a matching GET, relay upstream
+   (same upstream choice as today) and rewrite when models are returned. Messages dispatch unchanged.
+5. `src/claude/intercept/runtime.ts`: when picker routes and desired clients are wired, build a CLI snapshot
+   (`claude-intercept/cli-picker-models.json`), lazily refreshed (stale 5 min; first request waits ≤2.5 s), and pass
+   the hook. No timers, no discovery unless an eligible catalog request arrives.
+6. `src/server/management/agent-settings-routes.ts`: after a successful `cliFirstParty` change, invalidate the CLI
+   served-catalog cache (best effort) so the next `claude` launch refetches through the proxy.
+7. Tests: new `tests/claude-integration/claude-cli-picker.test.ts` (+ layout.json and test-layout-expected.json).
+8. Docs: `docs-site/.../guides/claude-code.md` paragraph; `structure/runtime.md` sentence on the catalog rewrite.
+
+## Verification
+
+Focused tests, `bun run typecheck`, `bun run test:changed`, `structure:check`, `privacy:scan`; live: dev server
+from this branch (isolated OPENCODEX_HOME with cliFirstParty + a provider that forwards to the running ocx),
+`~/.claude/settings.json` env applied through the real apply path, plain `claude` in tmux → `/model` lists routes
+→ pick one → prompt answered; settings and catalog cache restored afterwards.
+
+## Risks
+
+- Claude Code changes the catalog contract: rewrite is fail-open (unchanged bytes).
+- Aliases depend on the Desktop 3P registry built at startup; unregistered routes are omitted, not guessed.
+- UA classification is a hint, not a boundary (same as the Messages split).

+# 020 Audit fold
+
+Reviewer verdict: NEAR-PASS (independent subagent, read-only). Folded:
+
+1. Registry readiness — new `src/claude/desktop-3p-startup.ts`: `initDesktop3pRegistry(config)` (deduped, startup inputs incl.
+   entitlements) replaces the inline block in `src/cli/index.ts`; the CLI loader awaits it when the registry is empty.
+   Served rows are re-filtered against the live registry at response time.
+2. Bootstrap — the listener consults the catalog hook before the relay-native shortcut; bootstrap eligibility is
+   `desired.cli` only (its `claude-code/<v>` UA carries no entrypoint); upstream stays the route-selected one
+   (`CLAUDE_INTERCEPT_UPSTREAM` for unknown clients).
+3. cc rewrite only for clients classified `cli` with `desired.cli`; Desktop entrypoints untouched (test).
+4. Cache invalidation lives in `settings.ts` apply/remove (on change) and in `reconcileClaudeFirstPartySettings` (every ok
+   reconcile), covering the toggle route, ensure, disable and rollback paths. agent-settings-routes.ts is not touched.
+5. Logs carry kind/status/counts only. 8. CLI hook wired from `loadPickerRoutes`, independent of the Desktop picker.
+10. Desktop bootstrap output regression test. 13. Risk: `additionalModelOptionsCache` in `~/.claude.json` keeps
+   bootstrap rows until the CLI's next bootstrap fetch (every launch).
+Not folded: 7 (error text) — documented instead.

 Disabling Claude routing leaves the owned settings env untouched. While the bound listener still runs, every Messages request relays unchanged; after it stops, plain `claude` cannot connect until OpenCodex runs or Desktop/CLI first-party is turned off. Native `ocx claude` sets `NO_PROXY=*` only for an owned env without a foreign inherited `HTTPS_PROXY`/`https_proxy`. With a foreign proxy it preserves that value and warns that the settings-owned intercept still applies; turn Desktop/CLI first-party off or unset the setting.
 The UI distinguishes uncertainty about whether settings still point at its proxy (unknown), a token-bearing opencodex proxy with a foreign CA (foreign: fix HTTPS_PROXY / NODE_EXTRA_CA_CERTS manually), and a tokenless loopback proxy beside a foreign CA (local: ownership is unconfirmed; remove HTTPS_PROXY if unused). With matching applied settings and a bound listener but Claude routing off, disabled means requests relay unchanged until restart; turn first-party off to remove settings. An owned URL with no listener is stopped; a bound listener with an owned CA but mismatched port or token is broken even when routing is off. With an intent on, stopped or broken plus ineligible interception displays routingOff: Claude routing or the intercept is off, or this machine is a client of another opencodex hub; enable interception on this machine or turn first-party off to remove the settings. Only when interception is eligible does stopped advise starting opencodex and broken advise `ocx ensure` or restart. CLI intent with no proxy is not applied; one intent with a live proxy gets the shared-relay notice; any remaining proxy with neither intent is residual, unless unknown, foreign, or local takes precedence.

+#### Model picker in the CLI
+
+With the CLI first-party switch on and Claude routing enabled, start a new `claude` and open
+`/model`. Your opencodex models appear next to the Claude models from your account, labelled
+like "Grok 4.7 (xai)" and described with their route (`opencodex · xai/grok-4.7`). Picking one
+routes that session to the model, just like a binding.
+
+- Only new `claude` sessions pick up the list. Restart any session that was already running when
+  you turned the switch on or off.
+- Claude Code saves the list for about an hour. Turning the switch on or off, and `ocx ensure`,
+  clear that saved copy, so the next `claude` launch fetches a fresh one. If the routed models
+  are missing (the first launch after OpenCodex starts can miss them while models are still being
+  discovered), run `ocx ensure` and restart `claude`.
+- The rows use Claude-style ids (for example `claude-opus-4-8-…`), because the CLI only offers
+  ids shaped like Claude models. Claude Desktop's Code tab is unaffected; it keeps using
+  [first-party bindings](#use-opencodex-models-from-the-desktop-code-tab-first-party-bindings).

 (`src/claude/intercept/settings.ts`), so no `ANTHROPIC_BASE_URL` rewrite is involved and the client
 still believes it talks to Anthropic. The proxy splices `CONNECT api.anthropic.com:443` onto the TLS
 listener, relays every other CONNECT target blind, and refuses unauthenticated clients, plain proxied HTTP, and loopback targets. The per-install proxy token is stored owner-only under `<OPENCODEX_HOME>/claude-intercept/` (0600 plus a real per-user NTFS ACL on Windows, via `src/lib/windows-secret-acl.ts`, and re-pinned on every read-through `ensure`), and the settings file carrying it is written through the same hardened atomic writer. Every start runs `migrateClaudeInterceptSettings` (`src/claude/intercept/settings.ts`), which rewrites an owned env that no longer matches — e.g. a pre-auth URL left by an upgrade — while never creating an absent env or touching a foreign one, so a service restart cannot strand clients on 407s. Status/inspection reads the token without minting it; only apply and intercept startup create it.
-The TLS listener rewrites `POST /v1/messages` and `POST /v1/messages/count_tokens` to a loopback origin and dispatches them under the `claude-intercept` ingress; other paths relay to the configured upstream.
+The TLS listener rewrites `POST /v1/messages` and `POST /v1/messages/count_tokens` to a loopback origin and dispatches them under the `claude-intercept` ingress; other paths relay to the configured upstream. One relayed path is extended: for the standalone CLI's picker catalog, the listener's `cliCatalog` hook (`src/claude/intercept/cli-catalog.ts`) merges opencodex rows into `GET /api/organizations/<org>/model_selector/cc` (or `/api/model_selector/cc`), touching only the `cc` surface and leaving Desktop's `ccd`/`code` surfaces to picker mode, and into the fallback `additional_model_options` of `GET /api/claude_cli/bootstrap`. Eligibility: the `cc` catalog is rewritten only for a CLI-classified `User-Agent` with `claudeCode.cliFirstParty` on, because Claude Code caches it on disk for every process and a Desktop-spawned process must not seed rows a plain `claude` cannot route; the bootstrap request carries no entrypoint and follows CLI intent alone. Rows come from `buildCliPickerModels` (`src/claude/intercept/picker-models.ts`), which uses Desktop 3P registry aliases because the CLI offers only Claude-shaped ids (an `ocx-claude-*` row renders "Update Claude Code"), and advertises only an alias the registry decodes back to the same route. `src/claude/intercept/cli-picker.ts` supplies them lazily on the first eligible request, persists the snapshot at `<OPENCODEX_HOME>/claude-intercept/cli-picker-models.json`, re-checks each persisted row against the live registry (its alias must still decode to its recorded route; a cold registry after a restart is awaited first), and bounds a cold build at 2.5 s while awaiting the shared registry build in `src/claude/desktop-3p-startup.ts` that startup also uses (a failed or empty on-demand build is not retried for 30 s). The rewrite fails open: a provider error, non-2xx status, unparsable body, or no added row relays the upstream bytes unchanged; a body over the 16 MiB cap is cut off while streaming and answered 502 rather than buffered. Claude Code trusts its cached `<claudeConfigDir>/cache/model-catalog/*-cc.json` for about an hour, so `writeSettings` in `src/claude/intercept/settings.ts` and every successful `reconcileClaudeFirstPartySettings` drop those files (leaving Desktop's `*-ccd.json`); running sessions keep their list until restarted.
 The pair is on by default on a hub (`claudeCode.intercept.enabled`); its proxy port defaults to public port + 100 (`claudeCode.intercept.port`). Bind failure warns, and stop joins both sockets. With an ephemeral public port (`startServer(0)`), an explicit intercept port is required.
 This ingress honours first-party model bindings (`claudeCode.intercept.modelMap`); see [Claude Desktop](clients/claude-desktop.md#first-party-model-bindings). Picker mode and the primitive's optional `allowedTargets` restriction are described under [Desktop egress proxy](clients/claude-desktop.md#picker-mode-the-desktop-egress-proxy).

Subject: [PATCH 46/61] fix(service): scope Windows scheduler probes to the
 root task and re-probe deleted registrations (#6401)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three probe-scoping defects in the guarded Windows manager proof turned a
provable absent verdict into a permanent unknown (approval-changed) or a
permanent failed stop:

- windowsSchedulerCsvIncludesTask treated a backslash as a name boundary, so a
  same-named task inside a task folder (\Tools\opencodex-proxy) read as present
  while every /tn operation resolves a bare name in the root folder only — the
  bound read/stop then failed on a task nothing could reach.
- windowsScheduledTaskState ran Get-ScheduledTask -TaskName without -TaskPath,
  a folder-agnostic filter that returns foreign task state and arrays.
- inspectWindowsSchedulerManager read the registration XML before the state
  check, so an unreadable registration blocked the absent verdict an inert
  task does not need; and a task deleted between probes was indistinguishable
  from an unreadable one. The XML now loads only on the running path, and the
  unanswerable state/XML reads re-probe presence: proven-gone gets the
  stray-wrapper inert verdict, persisting or unanswerable stays unknown.
  observeWindowsGuardedManagerStopped re-probes the same way before failing
  closed, and proven absence still owes the unreadable former-manager check.

Verified live on Windows Server 2022: \DevinProbe\opencodex-proxy exists while
schtasks /query /tn, /end and /xml all fail root-scoped, the CSV listing emits
"\DevinProbe\opencodex-proxy", and Get-ScheduledTask -TaskName returns the
foldered task's state plus arrays for duplicate names. Regression tests pin
each failure and the preserved fail-closed cases.

 `ocx resolve` (`src/cli/resolve.ts`) is the machine surface a desktop shell asks instead of resolving the config home, the port, and liveness itself: the home comes from `src/config/paths.ts`, the effective port is the live listener's when the identity-checked `findLiveProxy` answers and the configured `config.port ?? 10100` otherwise, and the liveness verdict is that same module's output (pid, runtime-versus-config provenance, version, role). Config reads go through `readConfigDiagnostics`, not `loadConfig`: a missing file is defaults, but an invalid file exits 1 instead of being repaired to defaults, because a defaulted port is a guess the caller must refuse. Liveness is three-valued: when `findLiveProxy` returns null, resolve re-asks the endpoints with the updater's tri-state probe (`endpointsToProve` + `everyEndpointProvenDown` + `probeProxyLiveness`), and only a unanimous definitive "dead" becomes `absent-proven`; unknown exits 1 and never authorises a start. Discovery borrows `START_OWNERSHIP_LIVENESS`, the start path's ownership budget — the verdict feeds the shell's launch decision, so the cost of a false "nobody listening" is the duplicate proxy (#5004). The verb is in `skipsCodexShimAutoRestore`, so a read-only lookup never triggers a shim repair. Arguments are pre-parsed in `src/cli/root.ts` and exit 64 before any preflight side effect, the same ordering `ocx ready` obeys. `ocx-resolve/1` also reports `ownership` (`none`, `owned`, or `unknown`) and `takeover` (`supported` with protocol version, minimum CLI version and compatibility token, or `blocked` with a reason). A known liveness verdict still exits 0 when ownership is unknown, but takeover is blocked. An unreadable second service-state read blocks takeover instead of becoming an absent registration. `src/service/managing-cli.ts` observes the registered and selected PATH CLIs, including Windows PATHEXT order and file validation, before compatibility is offered.
 
-`ocx stop --json` is a reporting layer over the unchanged stop path. `src/cli/index.ts` threads a `StopRunRecord` through the existing receipt, drain, respawn-verification and restore flow, and `src/cli/stop-report.ts` maps the recorded facts plus the signals that already pick the exit code into one versioned document (`schema: "ocx-stop/1"`). With `--json` the human lines print on stderr and stdout carries only that document; exit codes 0/1/79/80 cross the process boundary unchanged. The desktop's opt-in guarded stop adds exact approved PID, endpoint, home, CLI version and compatibility-token expectations; plain `ocx stop` retains its ordinary behavior.

A pre-action mismatch returns `approval-changed` without stopping. Immediately before any manager stop or direct PID signal, the CLI rechecks the same manager identity or proven absence; a change also returns `approval-changed`. A non-OpenCodex process replacing the OS job in the remaining instant before the manager command is a residual same-user risk outside the ownership lease. The guarded path stops the bound manager, or the approved PID directly when managers are proven absent, then uses a five-second shared deadline to verify PID exit, port availability and definitive endpoint absence. Only after settlement does a read-only manager probe require launchd `not-loaded` in both domains or systemd `inactive` with `MainPID=0`; the state is checked again before a success summary. Timeout, active or unreadable manager state returns terminal `manager-still-active`, even if the endpoint briefly refuses. Windows managers bind through `src/service/windows-guarded-manager.ts`: a Task Scheduler backend must prove a recognized OpenCodex registration against the bounded current-user SID/name lookup, a running task, and a wrapper ancestor carrying this home's canonical paths; an unreadable current identity leaves the manager unknown; a WinSW backend must prove this installation's binary and SCM service PID ancestry; either marks `childNeedsSeparateStop`, so the approved PID receives its own graceful signal only after a successful manager stop because `schtasks /end` does not reliably cascade to the wrapper's child (#764); a failed or unknown manager stop leaves the child untouched. Post-stop Windows inactivity means the task not running, no surviving wrapper process, and no started WinSW — never mere registration presence. Every Windows manager command a verdict or stop depends on — schtasks, sc.exe, WinSW verbs — runs under a bounded `execFileSync` timeout so a wedged Task Scheduler or Service Control Manager cannot hang the guarded stop; a killed command classifies through the same fail-closed paths a nonzero exit would (the interactive `install /p` password prompt is the one deliberate exception). A `wscript.exe`, `cscript.exe` or `cmd.exe` whose command line CIM cannot read makes the state unprovable only when it is tied to the proxy: pre-stop, as an ancestor of the approved PID; post-stop, as the former bound manager process or a descendant of it.

Subject: [PATCH 47/61] fix(update): release the restart lease before the
 service refresh (#5760) (#6404)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(update): release the restart lease before the service refresh (#5760)

The dashboard update worker held the ownership-mutation lease across the
entire restart, including 'ocx service repair'. The service manager's
'ocx start' child is not a descendant of the worker — Task Scheduler,
launchd and systemd spawn it with the stored registration environment —
so it carries no delegated token, dies at the lease acquire deadline,
and the repair's serving probe fails. Every service-installed dashboard
update then fell through to an unmanaged detached start beside a dead
supervisor — the same class bin/ocx.mjs fixed for failed npm updates.

The restart callback now receives an UpdateRestartLeaseControl: the
worker releases the lease immediately before the service refresh and
re-runs the recorded-owner veto at the fallthrough boundary, so a claim
landing during the unleased refresh stops the direct start instead of
killing or replacing it. The job records the veto as
succeeded/restarted:false.

Regression coverage spawns a real supervised 'ocx start' against the
held lease (dies with the lease error), then drives restartAfterUpdate
through the service path post-fix (child binds and serves) and through
the fallthrough boundary under a mid-refresh claim (no kill, no spawn).

* fix(update): re-acquire the restart lease before the direct-start fallthrough (#5760)

The previous seam released the lease for the service refresh but left the
fallthrough's veto re-check, killAllOcxOnPort reclaim and pinned start
unleased — a desktop claim landing in that window could be killed.
reacquireForDirectStart takes the lease back (bounded; a still-claimed
lease fails closed), re-arms the delegation token, then re-runs the veto
under the held lease. Regression coverage: claim-in-window veto,
lease re-held through reclaim/direct start with a live contender probe,
and a real lease-holding child proving the bounded acquire fails closed.

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* test(update): resolve the restart-lease authority the way the module does

The suite pinned the lock dir to home/.opencodex, which is only the
Windows authority: USERPROFILE tracks the sandbox home there. On POSIX
homedir() ignores $HOME and the armed test-home guard drops that legacy
entry from serviceStatePaths(), so the lease binds to the OPENCODEX_HOME
record instead — existsSync(lockDir) was false at every step and the
spawned child's contention was never the path the test probed.

Resolve the authority with serviceStatePaths().at(-1) and mirror
leasePath()'s realpath fallbacks, so both the lock-dir assertions and the
foreign-claimant probes address the path the module actually locks.

* test(update): dump the held-lease child's output when it outlives the watchdog

The POSIX CI shard keeps this child alive past the watchdog; without its
stdout the stuck point is invisible. Log the captured output before the
watchdog throws.

* test(update): report the child's effective lock path on POSIX survival

The Linux child bound and served under the held lease, so its
serviceStatePaths() resolved a different authority — likely the legacy
home entry that the armed guard did not drop in the spawned env. Log the
candidates (os-homedir lock, env REAL_HOME, resolved paths) so the next
CI run shows which path it used.

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* Fix restart lease test child authority fixture

* Align restart child home with test guard

* fix(update): fail the job when the restart lease stays claimed after a non-serving refresh

 The npm transaction creates each staging directory exclusively and may clean that fresh path
 while the creating process still owns it. On POSIX it also creates the stage's `lib` directory,

+remains a reported recovery requirement. Dashboard restart delegates the lease token to its `service repair` child, and releases the lease before that refresh: the service manager spawns `ocx start` outside the worker's process tree with no token, so the managed child must take the lease itself (#5760). Before the direct-start fallthrough kills or spawns on the port, the worker takes the lease back — a refresh that stayed claimed stops the restart — and re-runs the recorded-owner veto under it because a claim could have landed during the unleased refresh window. Direct start holds the same lease through bind plus PID and runtime-address publication. If listener rollback cannot prove the socket closed, the process retains its lease until exit.
 The registration is never deleted; `ocx service install` releases the marker only after the
 registration succeeds.

Subject: [PATCH 48/61] fix(cli): stabilize guarded-stop re-verification and
 report the failing guard fact (#6402)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(cli): stabilize guarded-stop re-verification and report the failing guard fact

Three proven defects let an unchanged approved runtime read as changed:

- isOcxCommandLine/isOcxStartCommandLine rejected the bundled sidecar's
  `ocx-<target triple>[.exe]` binary name, so every desktop-spawned
  runtime failed identity verification at approval and re-resolution.
- The managing-CLI `--version` probe invoked a Windows command shim as
  `cmd /c <shim> --version`; cmd strips the outer quotes when more than
  one part is quoted, truncating the command at the first space whenever
  the shim path itself contains one. The shim now runs through a single
  verbatim-quoted /c line.
- Single-shot probes (the shim `--version` probe and the Windows
  WMIC/PowerShell command-line read) treated one transient timeout as
  'unobservable', flipping the compatibility fingerprint or PID identity
  of an unchanged process. Both get one bounded retry; a persistent
  failure still answers fail-closed.

The approval-changed summary also collapsed ~10 distinct re-checks into
one opaque message, so a transient re-probe was indistinguishable from
genuine drift. The summary now carries `detail` naming the single guard
fact that failed (token fingerprint vs live PID/port/hostname/CLI vs
manager verification), threaded through runGuardedManagerStep as well.
Addititive on ocx-stop/1; the desktop StopSummary tolerates the field.

* fix(cli): scope probe retry to Windows; drop unproven sidecar-triple identity widening

Review correction: real Tauri builds run the bundled CLI as ocx.exe and
native baseline ownership succeeded against it, so accepting
ocx-<target-triple> names in process identity was broadened on an
unproven launch path — reverted with its tests. The --version probe
retry is now Windows-only (the platform the flake family was verified
on); POSIX probes keep exactly one attempt.

* fix(cli): name the revalidation failure when the manager reads unknown

An unprovable manager (`kind: "unknown"` with a reason) is not a proven
swap, but the pre-action recheck reported both as 'the service manager
changed between approval and stop', losing why revalidation could not
answer. Unknown now surfaces as 'the service manager could not be
re-verified (reason)'; genuine mismatches keep the changed message.
Stop and signal still never run against an unknown target.

-`ocx resolve` (`src/cli/resolve.ts`) is the machine surface a desktop shell asks instead of resolving the config home, the port, and liveness itself: the home comes from `src/config/paths.ts`, the effective port is the live listener's when the identity-checked `findLiveProxy` answers and the configured `config.port ?? 10100` otherwise, and the liveness verdict is that same module's output (pid, runtime-versus-config provenance, version, role). Config reads go through `readConfigDiagnostics`, not `loadConfig`: a missing file is defaults, but an invalid file exits 1 instead of being repaired to defaults, because a defaulted port is a guess the caller must refuse. Liveness is three-valued: when `findLiveProxy` returns null, resolve re-asks the endpoints with the updater's tri-state probe (`endpointsToProve` + `everyEndpointProvenDown` + `probeProxyLiveness`), and only a unanimous definitive "dead" becomes `absent-proven`; unknown exits 1 and never authorises a start. Discovery borrows `START_OWNERSHIP_LIVENESS`, the start path's ownership budget — the verdict feeds the shell's launch decision, so the cost of a false "nobody listening" is the duplicate proxy (#5004). The verb is in `skipsCodexShimAutoRestore`, so a read-only lookup never triggers a shim repair. Arguments are pre-parsed in `src/cli/root.ts` and exit 64 before any preflight side effect, the same ordering `ocx ready` obeys. `ocx-resolve/1` also reports `ownership` (`none`, `owned`, or `unknown`) and `takeover` (`supported` with protocol version, minimum CLI version and compatibility token, or `blocked` with a reason). A known liveness verdict still exits 0 when ownership is unknown, but takeover is blocked. An unreadable second service-state read blocks takeover instead of becoming an absent registration. `src/service/managing-cli.ts` observes the registered and selected PATH CLIs, including Windows PATHEXT order and file validation, before compatibility is offered.

A known liveness verdict still exits 0 when ownership is unknown, but takeover is blocked. An unreadable second service-state read blocks takeover instead of becoming an absent registration. `src/service/managing-cli.ts` observes the registered and selected PATH CLIs, including Windows PATHEXT order and file validation, before compatibility is offered. A `--version` probe is retried once on Windows — one transient failure must not read as an unobservable CLI — and a Windows `.CMD`/`.BAT` shim is invoked through a single verbatim-quoted `cmd /c` line, so a spaced executable path and spaced arguments both survive cmd's re-parse.
 
-`ocx stop --json` is a reporting layer over the unchanged stop path. `src/cli/index.ts` threads a `StopRunRecord` through the existing receipt, drain, respawn-verification and restore flow, and `src/cli/stop-report.ts` maps the recorded facts plus the signals that already pick the exit code into one versioned document (`schema: "ocx-stop/1"`). With `--json` the human lines print on stderr and stdout carries only that document; exit codes 0/1/79/80 cross the process boundary unchanged. The desktop's opt-in guarded stop adds exact approved PID, endpoint, home, CLI version and compatibility-token expectations; plain `ocx stop` retains its ordinary behavior. Under the ownership mutation lease, `src/cli/stop-approval.ts` re-resolves them and `src/service/guarded-manager-target.ts` binds any installed manager's process tree to the approved PID before a stop action. A pre-action mismatch returns `approval-changed` without stopping. Immediately before any manager stop or direct PID signal, the CLI rechecks the same manager identity or proven absence; a change also returns `approval-changed`. A non-OpenCodex process replacing the OS job in the remaining instant before the manager command is a residual same-user risk outside the ownership lease. The guarded path stops the bound manager, or the approved PID directly when managers are proven absent, then uses a five-second shared deadline to verify PID exit, port availability and definitive endpoint absence. Only after settlement does a read-only manager probe require launchd `not-loaded` in both domains or systemd `inactive` with `MainPID=0`; the state is checked again before a success summary. Timeout, active or unreadable manager state returns terminal `manager-still-active`, even if the endpoint briefly refuses. Windows managers bind through `src/service/windows-guarded-manager.ts`: a Task Scheduler backend must prove a recognized OpenCodex registration against the bounded current-user SID/name lookup, a running task, and a wrapper ancestor carrying this home's canonical paths — presence and running state are read root-folder-scoped because every `/tn` operation resolves a bare name there and nowhere else, so a same-named task inside a task folder is a different registration neither the probe nor the stop can reach; the registered definition itself is read only on the running path, and a state or registration read that cannot answer re-probes presence so a task deleted between probes — which can respawn nothing — reads absent while a merely unreadable one stays unknown; an unreadable current identity leaves the manager unknown; a WinSW backend must prove this installation's binary and SCM service PID ancestry; either marks `childNeedsSeparateStop`, so the approved PID receives its own graceful signal only after a successful manager stop because `schtasks /end` does not reliably cascade to the wrapper's child (#764); a failed or unknown manager stop leaves the child untouched. Post-stop Windows inactivity means the task not running, no surviving wrapper process, and no started WinSW — never mere registration presence; a running-state read that cannot answer re-probes presence the same way, so a task deleted between probes reports inactive while a persisting one stays unknown. Every Windows manager command a verdict or stop depends on — schtasks, sc.exe, WinSW verbs — runs under a bounded `execFileSync` timeout so a wedged Task Scheduler or Service Control Manager cannot hang the guarded stop; a killed command classifies through the same fail-closed paths a nonzero exit would (the interactive `install /p` password prompt is the one deliberate exception). A `wscript.exe`, `cscript.exe` or `cmd.exe` whose command line CIM cannot read makes the state unprovable only when it is tied to the proxy: pre-stop, as an ancestor of the approved PID; post-stop, as the former bound manager process or a descendant of it. Unrelated unreadable shells, which a non-admin query returns for other users' and elevated processes, are not evidence either way. An unprovable Windows manager still blocks guarded takeover. The token checks snapshot consistency, not whether a person approved the desktop prompt. `src/cli/stop-restore.ts` owns the shared Codex/Grok restoration and its history-only, history-deferred, and other failure categories.

Subject: [PATCH 49/61] fix(claude): rebuild a CLI picker snapshot whose rows
 no longer decode (#6419)

* fix(claude): rebuild a CLI picker snapshot whose rows no longer decode

A snapshot persisted under an earlier provider setup can list routes the
current registry no longer decodes. The provider filtered them out and answered
with no opencodex rows until the 5-minute refresh, and Claude Code cached that
empty list for an hour. Rebuild the snapshot within the cold-wait bound instead.

* docs(structure): note the CLI picker snapshot rebuild

* fix(claude): share one cold-wait deadline and keep the snapshot when the registry build fails

 (`src/claude/intercept/settings.ts`), so no `ANTHROPIC_BASE_URL` rewrite is involved and the client
 still believes it talks to Anthropic. The proxy splices `CONNECT api.anthropic.com:443` onto the TLS
 listener, relays every other CONNECT target blind, and refuses unauthenticated clients, plain proxied HTTP, and loopback targets. The per-install proxy token is stored owner-only under `<OPENCODEX_HOME>/claude-intercept/` (0600 plus a real per-user NTFS ACL on Windows, via `src/lib/windows-secret-acl.ts`, and re-pinned on every read-through `ensure`), and the settings file carrying it is written through the same hardened atomic writer. Every start runs `migrateClaudeInterceptSettings` (`src/claude/intercept/settings.ts`), which rewrites an owned env that no longer matches — e.g. a pre-auth URL left by an upgrade — while never creating an absent env or touching a foreign one, so a service restart cannot strand clients on 407s. Status/inspection reads the token without minting it; only apply and intercept startup create it.
-The TLS listener rewrites `POST /v1/messages` and `POST /v1/messages/count_tokens` to a loopback origin and dispatches them under the `claude-intercept` ingress; other paths relay to the configured upstream. One relayed path is extended: for the standalone CLI's picker catalog, the listener's `cliCatalog` hook (`src/claude/intercept/cli-catalog.ts`) merges opencodex rows into `GET /api/organizations/<org>/model_selector/cc` (or `/api/model_selector/cc`), touching only the `cc` surface and leaving Desktop's `ccd`/`code` surfaces to picker mode, and into the fallback `additional_model_options` of `GET /api/claude_cli/bootstrap`. Eligibility: the `cc` catalog is rewritten only for a CLI-classified `User-Agent` with `claudeCode.cliFirstParty` on, because Claude Code caches it on disk for every process and a Desktop-spawned process must not seed rows a plain `claude` cannot route; the bootstrap request carries no entrypoint and follows CLI intent alone. Rows come from `buildCliPickerModels` (`src/claude/intercept/picker-models.ts`), which uses Desktop 3P registry aliases because the CLI offers only Claude-shaped ids (an `ocx-claude-*` row renders "Update Claude Code"), and advertises only an alias the registry decodes back to the same route. `src/claude/intercept/cli-picker.ts` supplies them lazily on the first eligible request, persists the snapshot at `<OPENCODEX_HOME>/claude-intercept/cli-picker-models.json`, re-checks each persisted row against the live registry (its alias must still decode to its recorded route; a cold registry after a restart is awaited first), and bounds a cold build at 2.5 s while awaiting the shared registry build in `src/claude/desktop-3p-startup.ts` that startup also uses (a failed or empty on-demand build is not retried for 30 s). The rewrite fails open: a provider error, non-2xx status, unparsable body, or no added row relays the upstream bytes unchanged; a body over the 16 MiB cap is cut off while streaming and answered 502 rather than buffered. Claude Code trusts its cached `<claudeConfigDir>/cache/model-catalog/*-cc.json` for about an hour, so `writeSettings` in `src/claude/intercept/settings.ts` and every successful `reconcileClaudeFirstPartySettings` drop those files (leaving Desktop's `*-ccd.json`); running sessions keep their list until restarted.

 The pair is on by default on a hub (`claudeCode.intercept.enabled`); its proxy port defaults to public port + 100 (`claudeCode.intercept.port`). Bind failure warns, and stop joins both sockets. With an ephemeral public port (`startServer(0)`), an explicit intercept port is required.
 This ingress honours first-party model bindings (`claudeCode.intercept.modelMap`); see [Claude Desktop](clients/claude-desktop.md#first-party-model-bindings). Picker mode and the primitive's optional `allowedTargets` restriction are described under [Desktop egress proxy](clients/claude-desktop.md#picker-mode-the-desktop-egress-proxy).

Subject: [PATCH 50/61] fix(claude): start the intercept pair on demand instead
 of asking for a restart (#6428)

* devlog: Claude UX roadmap (intercept on demand, Claude page, app rebuild)

* fix(claude): start the intercept pair on demand instead of asking for a restart

Saving CLI or Desktop first-party settings refused with "restart needed" when the
intercept pair had not bound at startup (Claude routing off, port busy, etc). The
lifecycle now has a serialized ensure() that starts the pair in the running
process through the same dispatch wrapper, records why a start failed
(disabled, client role, ephemeral port, port in use, port mismatch) and is
called by the first-party, Desktop picker and Claude routing toggles plus a new
local-only POST /api/claude-intercept/start. The GUI shows the reason and a
Start interception action; no copy asks for a restart.

* fix(claude): gate intercept start on enable paths, reject a changed port, add ocx claude intercept start

* fix(claude): report intercept start failures from the native toggle and the picker bind port

+# 261002 Claude UX — roadmap (010)
+
+Three outcomes, four work-phases (wp1 = this roadmap).
+
+| wp | Unit | Doc | Branch |
+| --- | --- | --- | --- |
+| wp2 | Start the Claude intercept pair on demand instead of asking for a restart | 020 | `codex/claude-intercept-on-demand` |
+| wp3 | Top-level Claude page under Codex: Account / Code / Desktop / Settings | 030 | `codex/gui-claude-page` |
+| wp4 | Local OpenCodex.app rebuild from merged dev, install handed to the user | 040 | none |
+
+## Evidence
+
+- `startClaudeIntercept` (src/claude/intercept/runtime.ts) runs once, from `createClaudeInterceptLifecycle().start` in
+  src/server/index/optional-listeners.ts at `startServer`. It resolves `null` when Claude routing is off
+  (`claudeCode.enabled === false`), the intercept is disabled, the role is `client`, or the public port is ephemeral, and a
+  bind failure only warns. Nothing starts it later, so `getClaudeInterceptState()` stays `null` for the life of the process.
+- The CLI first-party toggle (`PUT /api/claude-code {cliFirstParty}`, agent-settings-routes.ts:1557) then refuses with
+  `intercept_unavailable` ("…restart needed"), and the Desktop panel shows `claudeDesktop.firstParty.proxyStopped`:
+  "로컬 프록시 127.0.0.1:{port}가 실행 중이 아님 — OpenCodex 재시작". `claude.firstParty.disabled` also tells the user to restart.
+  The live user config has `claudeCode.enabled: false`, `desktopMode: first-party`, which reproduces it.
+- The Desktop picker controller and runtime are created inside `startClaudeIntercept` only, so the picker is also absent.
+
+## Order
+
+wp2 and wp3 are independent and run in parallel lanes (separate worktrees). wp3 rebases after wp2 merges if both touch
+ClaudeCode/ClaudeDesktop copy. wp4 needs both merged.

+# 020 Intercept on demand (wp2)
+
+## Behaviour
+
+- A serialized, idempotent `ensureClaudeIntercept()` starts the intercept pair (CONNECT proxy, TLS listener, CLI catalog hook,
+  Desktop picker runtime/controller when wired) in the running process using the persisted config, reusing the options the
+  lifecycle got at `startServer` (dispatch, ports, picker routes). A second call while one is in flight awaits the same start;
+  a call when already bound returns the bound state.
+- Result is a discriminated outcome: `{ok:true,state}` or `{ok:false, reason}` with reason
+  `disabled` (Claude routing off or `claudeCode.intercept.enabled=false`), `client_role`, `ephemeral_port`,
+  `port_in_use` (with the port), `failed` (message without secrets). No reason means "restart".
+- Callers: the `cliFirstParty` toggle and every Desktop first-party/picker apply route call it before refusing; turning Claude
+  routing on (`PUT /api/native-integrations/claude {enabled:true}`) calls it; a new `POST /api/claude-intercept/start`
+  (dashboard session) lets the GUI retry explicitly. Status payloads gain `interceptReason` so the GUI can say why.
+- Turning routing off does not tear the pair down (existing relay-native behaviour stays).
+- The startup path keeps its synchronous contract (AGENTS.md: no await between `Bun.serve` and lab activation); the lifecycle
+  only records its options and a starter, it does not change the startup order.
+
+## GUI
+
+- Replace every "restart OpenCodex" instruction for the intercept (ko/en/... `claudeDesktop.firstParty.proxyStopped`,
+  `claude.firstParty.disabled`, `claude.firstParty.refusal.interceptUnavailable`) with the concrete reason plus a
+  "Start" action that calls the new endpoint, and a port hint for `port_in_use`
+  (`claudeCode.intercept.port`). All locales updated.
+
+## Tests
+
+Lifecycle: ensure starts when startup returned null, is idempotent and serialized, maps EADDRINUSE to `port_in_use`.
+Route: `cliFirstParty:true` with no bound intercept starts it and succeeds; disabled routing returns `disabled`.
+Desktop status reports `interceptReason`. File-size: keep agent-settings-routes.ts under 2000 lines (move to a sibling).

+# 050 Audit fold (wp1)
+
+Independent inherited-model reviewer: NEAR-PASS. Folded into 020/030 as binding requirements:
+
+1. `ensureClaudeIntercept` is a method of `ClaudeInterceptLifecycle` (claude-intercept-lifecycle.ts), so a later start goes
+   through the same dispatch wrapper (`listener ??= requestServer`) and `ownsListener` classifies it as the intercept ingress;
+   expose it through `OptionalListenerSet` and the existing `linkListener: () => optionalListeners` seam (index.ts gains no lines).
+2. One `inflight` promise; `stopped` flag refuses ensure after stop; `stop()` awaits the in-flight start; ensure awaits a
+   pending startup start first and only starts a new pair if it resolved to null.
+3. Record the last start outcome: pure precheck (disabled / client role / ephemeral port) plus bind error mapping
+   (EADDRINUSE on the CONNECT proxy → `port_in_use` with port). Picker proxy bind failure stays non-fatal and is reported as
+   `pickerReason`.
+4. Port mismatch (bound port ≠ configured) gets reason `port_mismatch`: rebind is out of scope; the copy explains the bound port
+   is in use for this run and how to change it, never "restart".
+5. Use startServer's live config object; recompute `observeClaudeDesktopMode` on each ensure.
+6. Security: ensure (POST /api/claude-intercept/start and the triggering PUTs) is refused on the hub-management ingress and for
+   data-plane API keys; same gate everywhere; tests prove it.
+7. GUI routing list for wp3: app-routing.ts (Page union, page list, `#claude` redirect inverted), App.tsx title map + NAV,
+   `nav.claude` and all copy in all locales, INTEGRATION_TAB_HASHES old hashes kept as redirects, integration-tabs.ts:34,
+   overview-clients.ts:318/367, api-surface-cards.tsx:20, Integrations.tsx:20, Claude.tsx:10-11.
+
+Notes kept: agent-settings-routes.ts sibling move up front (1943/2000); a later start may run picker CA drain/keychain → GUI
+pending state; routing off keeps the pair bound (relay-native).

 Turn on the CLI switch in Claude → Code, or run `ocx claude config set --first-party on`; use `off` to disable it. The switch is immediate and refuses `{enabled:false, cliFirstParty:true}` before any field is saved; it may also refuse to turn on if the local intercept is unavailable, the CA cannot be prepared, settings cannot be read, or a foreign proxy setting owns the keys. Off persists even when the intercept is unavailable; disabling Claude routing alone leaves an owned settings env untouched. For fully native terminal traffic with only Desktop first-party on, set `NO_PROXY='*'` in the shell. This still carries the first-party account risk stated above.
 Disabling Claude routing leaves the owned settings env untouched. While the bound listener still runs, every Messages request relays unchanged; after it stops, plain `claude` cannot connect until OpenCodex runs or Desktop/CLI first-party is turned off. Native `ocx claude` sets `NO_PROXY=*` only for an owned env without a foreign inherited `HTTPS_PROXY`/`https_proxy`. With a foreign proxy it preserves that value and warns that the settings-owned intercept still applies; turn Desktop/CLI first-party off or unset the setting.
-The UI distinguishes uncertainty about whether settings still point at its proxy (unknown), a token-bearing opencodex proxy with a foreign CA (foreign: fix HTTPS_PROXY / NODE_EXTRA_CA_CERTS manually), and a tokenless loopback proxy beside a foreign CA (local: ownership is unconfirmed; remove HTTPS_PROXY if unused). With matching applied settings and a bound listener but Claude routing off, disabled means requests relay unchanged until restart; turn first-party off to remove settings. An owned URL with no listener is stopped; a bound listener with an owned CA but mismatched port or token is broken even when routing is off. With an intent on, stopped or broken plus ineligible interception displays routingOff: Claude routing or the intercept is off, or this machine is a client of another opencodex hub; enable interception on this machine or turn first-party off to remove the settings. Only when interception is eligible does stopped advise starting opencodex and broken advise `ocx ensure` or restart. CLI intent with no proxy is not applied; one intent with a live proxy gets the shared-relay notice; any remaining proxy with neither intent is residual, unless unknown, foreign, or local takes precedence.

When interception is stopped, use **Start interception** or `ocx claude intercept start` to retry within the running OpenCodex service. Saving first-party settings also starts it automatically. A refusal reports disabled routing, client role, an ephemeral public port, an occupied port, or a startup failure. For an occupied port, free it or set `claudeCode.intercept.port`. If a pair is already bound on a different port, the response names both ports; use the bound port or restore the configured value. CLI intent with no proxy is not applied; one intent with a live proxy gets the shared-relay notice; any remaining proxy with neither intent is residual, unless unknown, foreign, or local takes precedence.
 
 - Gateway discovery (`/model` → "From gateway") is not used, because Claude Code only queries
   `GET /v1/models` on a configured gateway. Routed models reach the picker another way; see

Management-authenticated, declared non-mutating, and they write nothing: no snapshot, no lock, no maintenance, no recovery. They answer `409 integration_preview_unavailable` rather than gathering a model roster, because discovery refreshes credentials and writes the provider cache. Responses carry only declared managed schema paths, closed change kinds and an opaque fingerprint; no value, filesystem location or selected member identity appears. Mutation routes accept `operation` and `planFingerprint` together or not at all, reject a half-bound request and an operation that disagrees with the change, and answer `409 integration_preview_stale` with a freshly computed plan. Binding is an optimistic token, never authorization. [The integration contract](clients/integrations.md) owns the ordering. |

 still believes it talks to Anthropic. The proxy splices `CONNECT api.anthropic.com:443` onto the TLS
 listener, relays every other CONNECT target blind, and refuses unauthenticated clients, plain proxied HTTP, and loopback targets. The per-install proxy token is stored owner-only under `<OPENCODEX_HOME>/claude-intercept/` (0600 plus a real per-user NTFS ACL on Windows, via `src/lib/windows-secret-acl.ts`, and re-pinned on every read-through `ensure`), and the settings file carrying it is written through the same hardened atomic writer. Every start runs `migrateClaudeInterceptSettings` (`src/claude/intercept/settings.ts`), which rewrites an owned env that no longer matches — e.g. a pre-auth URL left by an upgrade — while never creating an absent env or touching a foreign one, so a service restart cannot strand clients on 407s. Status/inspection reads the token without minting it; only apply and intercept startup create it.
 The TLS listener rewrites `POST /v1/messages` and `POST /v1/messages/count_tokens` to a loopback origin and dispatches them under the `claude-intercept` ingress; other paths relay to the configured upstream. One relayed path is extended: for the standalone CLI's picker catalog, the listener's `cliCatalog` hook (`src/claude/intercept/cli-catalog.ts`) merges opencodex rows into `GET /api/organizations/<org>/model_selector/cc` (or `/api/model_selector/cc`), touching only the `cc` surface and leaving Desktop's `ccd`/`code` surfaces to picker mode, and into the fallback `additional_model_options` of `GET /api/claude_cli/bootstrap`. Eligibility: the `cc` catalog is rewritten only for a CLI-classified `User-Agent` with `claudeCode.cliFirstParty` on, because Claude Code caches it on disk for every process and a Desktop-spawned process must not seed rows a plain `claude` cannot route; the bootstrap request carries no entrypoint and follows CLI intent alone. Rows come from `buildCliPickerModels` (`src/claude/intercept/picker-models.ts`), which uses Desktop 3P registry aliases because the CLI offers only Claude-shaped ids (an `ocx-claude-*` row renders "Update Claude Code"), and advertises only an alias the registry decodes back to the same route. `src/claude/intercept/cli-picker.ts` supplies them lazily on the first eligible request, persists the snapshot at `<OPENCODEX_HOME>/claude-intercept/cli-picker-models.json`, re-checks each persisted row against the live registry (its alias must still decode to its recorded route; a cold registry after a restart is awaited first, and a snapshot whose rows still do not decode, for example after a provider change, is rebuilt within the same bound), and bounds a cold build at 2.5 s while awaiting the shared registry build in `src/claude/desktop-3p-startup.ts` that startup also uses (a failed or empty on-demand build is not retried for 30 s). The rewrite fails open: a provider error, non-2xx status, unparsable body, or no added row relays the upstream bytes unchanged; a body over the 16 MiB cap is cut off while streaming and answered 502 rather than buffered. Claude Code trusts its cached `<claudeConfigDir>/cache/model-catalog/*-cc.json` for about an hour, so `writeSettings` in `src/claude/intercept/settings.ts` and every successful `reconcileClaudeFirstPartySettings` drop those files (leaving Desktop's `*-ccd.json`); running sessions keep their list until restarted.
-The pair is on by default on a hub (`claudeCode.intercept.enabled`); its proxy port defaults to public port + 100 (`claudeCode.intercept.port`). Bind failure warns, and stop joins both sockets. With an ephemeral public port (`startServer(0)`), an explicit intercept port is required.
+The pair is on by default on a hub (`claudeCode.intercept.enabled`); its proxy port defaults to public port + 100 (`claudeCode.intercept.port`). The lifecycle records bind failure, and stop joins both sockets. Its serialized `ensure()` joins pending startup, reuses the live config and dispatch wrapper, and can start a previously unbound pair. `stop()` refuses future ensure calls and awaits an in-flight start. Local management applies and `ocx claude intercept start` (`POST /api/claude-intercept/start`) use this seam through `src/server/index/optional-listeners.ts`; hub-management ingress and data-plane credentials cannot start interception. Status reports `interceptReason` (with `interceptFailurePort` for a CONNECT bind failure) and optional `pickerReason` (with `pickerFailurePort` when the Desktop picker relay port is occupied), distinguishing disabled routing, client role, ephemeral public ports, occupied CONNECT ports and other failures. A changed configured port never rebinds a running pair: apply reports `port_mismatch` with both ports. With an ephemeral public port (`startServer(0)`), an explicit intercept port is required.
 This ingress honours first-party model bindings (`claudeCode.intercept.modelMap`); see [Claude Desktop](clients/claude-desktop.md#first-party-model-bindings). Picker mode and the primitive's optional `allowedTargets` restriction are described under [Desktop egress proxy](clients/claude-desktop.md#picker-mode-the-desktop-egress-proxy).
 
 `src/claude/intercept/client-class.ts` classifies each request by its Claude Code `User-Agent` entrypoint: `claude-desktop`, `claude-desktop-3p`, and `local-agent` are Desktop; other well-formed `claude-cli/<v> (external, <entrypoint>)` values are CLI; absent or malformed values are unknown.

 Usage heatmap days have one Tab entry point. Use Up/Down for adjacent days and Left/Right for adjacent weeks. Weekly bars expose the same day details on keyboard focus, pointer hover, or touch. Day labels include the date, request count, and token count; tooltip overlays stay within the viewport.
+
+### Claude
+
+The **Claude** sidebar page sits directly below **Codex**. One header and tab strip stay in place while you switch tabs, ordered Account, Code, Desktop, Settings. The Account tab shows what the Anthropic provider's **Accounts** tab shows on **Providers**: login, the browser option, the Claude account roster with switch, pause, remove, and reauthentication, the paste-code field, account pool settings, and quota. Provider-level controls such as the default provider, removal, and the enabled switch stay on **Providers**. When Anthropic is not configured, **Add Anthropic** starts Claude sign-in directly, after the same risk notice the Add provider dialog shows. Opening Claude without a tab selects Account when Anthropic is configured, otherwise Code. Code holds the Claude connection switch; Settings shows that connection as On or Off, interception as Running or Stopped, and the intercept port. When interception is stopped, Settings shows why and offers **Start interception**, which starts it in place without restarting OpenCodex. On Desktop, one status row shows whether Claude Desktop runs the profile and whether it is saved, with Save and Save & apply beside it. Compatibility, agent instructions, and context controls remain on Code.
+
+Bookmarks select a tab directly: `#claude/account`, `#claude/code`, `#claude/desktop`, and `#claude/settings`. The former `#integrations/claude` and `#integrations/claude/desktop` bookmarks redirect to Code and Desktop. Arrow keys move between tabs; Home and End select the first and last tab.

Subject: [PATCH 52/61] fix(gui): conditions-based Claude account-pool and
 OAuth warning copy (#6440)

* fix(gui): conditions-based Claude account-pool and OAuth warning copy

The Claude account-pool card showed an always-on role="alert" box ("Experimental and
not battle-tested ... Keep this off unless you understand the risk") that told operators
neither what the pool changes nor that 429 failover keeps running with it off.

The card now states the conditions the pool is meant for as static helper text: your own
or authorized subscriptions, the genuine Claude Code client, a person supervising the
session, Anthropic's current terms, and shared organization quota. A closed "How account
selection works" disclosure explains what enabling changes, that a 429 or classified
account refusal still fails over when the pool is off (pause an account to exclude it),
and the default background activity (no keep-warm requests, no background token refresh
or usage polling; usage is read when the dashboard, menu bar app or an ocx command asks).
Threshold help calls the threshold a preference, not a usage or billing cap. Save failures
remain the only live alert.

The OAuth terms dialog gets Anthropic-specific title, body, conditions, API-key
alternative, acknowledgement and continue copy, selected by oauthTosCopyKeys. Other
providers keep the shared keys; the unchecked acknowledgement, Cancel/Escape/backdrop and
single submit are unchanged. All ten locales carry the same claims; the Claude guide and
config references drop the old "not battle-tested" wording.

The copy describes only behavior that ships today and claims no account-pool mechanism
that is still in progress. Framing informed by KarpelesLab/teamclaude docs/compliance.md (MIT); no code ported.

* fix(gui): match the Claude pool status line to the selected strategy

The enabled status line said new sessions and refusal recovery follow the quota window
even under round-robin, where pickUnboundStrategyAccount and pickAlternateAnthropicAccount
rotate through the ring without reading usage, the threshold or the window (and the
window selector is disabled). The line is now chosen by strategy:

- round-robin: sessions and refusal recovery take turns; usage, threshold and window unused
- fill-first: the active account is drained to the threshold in the window (or, at 0, kept
  until cooldown or sign-in), then the next account in order; recovery also takes the next
- quota: unchanged above 0; at 0 a healthy active account stays and the lowest-usage account
  in the window is chosen only when it is unavailable or during refusal recovery

The details line now says the selected strategy chooses accounts instead of naming the
threshold and window. All ten locales carry the same claims and placeholders.

structure/dashboard-and-usage.md said load and save failures are both alerts; only a failed
save has role="alert", while a failed load replaces the status line and disables the toggle.

 To bind a model to particular stored Claude accounts, add ordered `anthropicAccountPool.routes` rules while the pool is enabled. Each rule has a safe `name`, a full case-sensitive `match` glob, an `accounts` array of stored account IDs, and optional `fallback` (default `false`). The first matching rule limits active, manual, affinity, strategy and 429 recovery picks to its accounts. A healthy affinity outside that rule is ignored for this request but kept for other models; the routed choice does not overwrite it. Without fallback, an empty route returns a local 401, or 429 with `Retry-After` when all its declared accounts are cooling, before contacting Anthropic. The client response does not name the route; the proxy log records `route:#<n>`, where `n` is the rule’s 1-based position. `fallback: true` uses the ordinary pool only when the route has no eligible account, including its ordinary fill-first successor order; if its stored accounts are all cooling, the returned 429 uses the earliest cooldown across that expanded pool, even if a saved route account has been removed. An unmatched model follows the existing pool policy; disabling the pool leaves saved rules inactive and restores active-account and presence-driven 429 behavior. A rule is an operator allowlist, not proof of model entitlement.

Each mount starts unchecked, and Cancel, Escape and the backdrop never start OAuth (`gui/tests/oauth-tos-warning-modal.test.tsx`). The Claude account-pool card states its usage conditions as static helper text with a closed details disclosure. Only a failed save is announced as an alert (`role="alert"`); a failed load replaces the status line with static text and disables the toggle. The enabled status line is chosen by strategy, so round-robin never claims to read usage, the threshold or the quota window (`gui/tests/anthropic-pool-conditions.test.tsx`).

Subject: [PATCH 53/61] fix(anthropic): bind native Claude metadata and client
 identity to the serving OAuth account (#6442)

* fix(anthropic): bind native metadata to serving OAuth credential

* fix(anthropic): preserve observed Claude Code native request identity

* fix(anthropic): preserve operator headers and guard all OAuth builds

* docs(structure): scope Claude identity continuity to unpooled native switches

 `OCX_SERVICE=1`, so managed restarts do not repeatedly restore/reinject; explicit service stop and
 uninstall still restore. `src/service/cli.ts` removes the service token on uninstall only when persisted client state is disconnected and no pending connect marker owns the newly issued key. `src/client/connect.ts` publishes that fingerprint marker before the key, then clears it with the connection commit or rollback under the client lifecycle and config mutation locks. Connected, invalid, or mismatched client state retains an existing token. A valid pending marker retains only its matching fingerprint; an older marker does not own a replacement service key. An absent token is reported as absent; unsafe, malformed, or unreadable markers and lock, state-read, or deletion failures leave cleanup unverified.
 `src/cli/tray-proxy.ts` coordinates `ocx restart` and tray restart. A second start requires proof the prior attempt never launched or its child exited, plus confirmed absence under a fresh bounded discovery window; a missing health response alone is insufficient. After an accepted restart, polling continues through uncertain observations until its deadline and requires a new runtime PID on the same port. If the old proxy then disappears, explicit recovery starts it regardless of the Codex autostart preference; a skipped recovery fails rather than reporting success.

+The package-tree integrity fence for live package replacement follows the [update transaction contract](ops/docs-and-release.md#package-tree-integrity-fence). After client journal reconciliation, `ocx ensure` in `src/cli/dispatch.ts` treats validated connected-client state as a successful no-op without local startup or a remote health probe; invalid or mismatched state still fails, and disconnected state keeps local ensure. `tests/cli/cli-ensure-client-state.test.ts` pins this dispatch contract so the Codex shim does not warn merely because its proxy is delegated to a hub.
 
 A busy preferred port is never resolved by starting somewhere else. Both questions a start asks
 about an existing proxy — the pre-bind owner check and the port-is-busy check in `src/cli/index.ts`

 The Anthropic helper sends share the same routing authority: `getAnthropicSidecarAccessToken` resolves the vision-describe and web-search sidecars' helper model through the same first-match route decision, so a routed send authenticates as the route's own account rather than whatever pool account happens to be active. A strict route with no eligible account fails the helper locally instead of silently falling back to the active outsider, matching the primary-traffic contract; callers without a pool config keep the plain stored-credential path.

+## Classified 429 admission
+
+`src/oauth/anthropic-rate-limit-policy.ts` classifies trusted unified headers before
+`src/oauth/anthropic-account-refusal.ts` changes health. Shared 5h/7d rejection or an
+aggregate unified rejection without a family-specific rejection cools only the sending
+credential's account, including the final budget refusal. An aggregate-only refusal uses
+its unified reset or the sixty-second default; Retry-After retains precedence. Family-only
+rejection does not assert shared exhaustion. A transient Retry-After pauses account admission
+without clearing affinity; a request gets one same-account wait up to one second and at most
+one eligible sibling detour. Timer rounding at the captured retry deadline permits that
+retry, while a concurrent admission-pause extension still blocks it. Headerless/invalid-hint
+refusals get at most one short same-account
+retry and never cool the roster or invent a client Retry-After. Main, pre-output continuation
+and sidecars share the request-local allowance and physical-send budget. Cancellation,
+ambiguous-send markers, replaced credentials and committed streaming output forbid replay.
+Default single-account users acquire no new retry or admission pause.
+
+Regression coverage: `tests/adapters/anthropic/anthropic-429-policy.test.ts`.
+
+## Family weekly admission
+
+`src/providers/quota/anthropic-family-headers.ts` attributes 7d_oi only to fixture-confirmed
+Fable 5 models. It preserves independent shared and model windows, including rejection-only
+family evidence only on HTTP 429, without advancing the usage-probe clock. Other response
+statuses retain soft utilization without creating a hard family refusal.
+`src/oauth/anthropic-model-quota.ts` reads shared 5h/weekly and only the requested family's scoped weekly. Manual, affinity,
+strategy, reactive selection and physical dispatch use that model. A family-only refusal
+preserves unrelated sessions and account-wide health. Numeric thresholds stay soft: zero
+and the all-drained fallback remain preferences, with no hard billing cap introduced.
+
+Passive family evidence expires after thirty minutes or its known reset. An expired
+exclusion admits one request-driven revalidation send at a time, released at response
+headers or error, without a background probe. An owned 2xx retires the requested family
+exclusion even without family headers, restoring concurrent sends. Family mutations use a
+separate generation fence: a newer family observation preserves its own evidence while an
+in-flight usage probe may still recover shared cooldown and publish shared utilization.
+Credential replacement discards old passive ownership. Active non-enumerating probes preserve absent family windows; an authoritative
+limits array retires absent families. Shared rejection and family rejection keep independent
+resets, so Fable must wait for both relevant windows while Sonnet need only wait for shared quota.

 # Responses Failover And Replay
 
  `src/server/responses/request-transport.ts` resolves the final Anthropic model ID once for each enabled-pool request and holds its model route through admission. The three account-refusal retry sites in `adapter-dispatch.ts`, `adapter-continuation.ts` and `sidecar-execution.ts` use the same route, keep the original refusal if no replacement exists inside it, and preserve existing send and output replay limits. A local cooldown returns 429 with the earliest known Retry-After among accounts the route can use when they recover; explicit fallback includes usable ordinary-pool accounts even when the saved route IDs have been removed, while a strict route stays route-scoped. Selection, refusal and 429-rotation logs use the rule’s 1-based `route:#<n>` position, never its name.

Date: Fri, 2 Oct 2026 19:58:39 +0900
Subject: [PATCH 56/61] fix(streaming): decode CR, LF and CRLF server-sent
 events across chunks (carry #6439) (#6446)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(streaming): decode CR-delimited server-sent events

* fix: address review feedback for PR #6439

* fix(streaming): keep CR/LF delimiter search native and cover split CRLF framing

Carry follow-up for #6439. Replace the per-character delimiter loop with cached
indexOf cursors for the next CR and LF, so the shared decoder keeps native,
linear scanning on every provider stream. Add explicit cases for a CRLF split
between chunks (including an empty chunk in between), LFCR, many records in one
chunk for each framing, a UTF-8 code point split next to CR, and raw versus
escaped CR in data. Give the Korean guide section a Korean heading and record
the cursor search in the byte-accounting owner doc.

GET의 HTTP 실패는 상태 조회를 종료하지만, 두 번째 로그인 POST를 보내지 않고 취소를 다시 시도할 수 있습니다. 종료 상태인 `failed` 응답은 흐름을 해제하고 정규화된 실패 사유를 표시하며, `succeeded` 응답만 로그인 성공을 알립니다. `cancelled`로 확인된 응답은 흐름을 해제하여 새 기기 코드 로그인을 시작할 수 있게 합니다. HTTP 404와 `unknown_flow` 코드가 명확하게 반환된 경우에도 만료된 흐름 ID를 해제하여 새 기기 코드 로그인을 시작할 수 있게 하지만, 로그인 성공이나 취소 확정으로 표시하지 않습니다. 이전 흐름에서 늦게 도착한 POST·GET·DELETE 응답은 새 흐름을 변경하거나 새 흐름의 로그인이 성공했다고 알릴 수 없습니다.

+## 스트리밍 줄바꿈
+
+공유 SSE 디코더는 LF, CRLF 및 단독 CR 줄바꿈을 처리하며 네트워크 청크 사이에서 구분자가 나뉘어도 동작합니다. 호환 제공자는 LF 형식으로만 스트림을 만들 필요가 없습니다.

+`src/lib/sse-decoder.ts` recognizes CR, LF and CRLF line endings, including CRLF split between fetch chunks. Delimiters are consumed before field retention; event/comment ordering, EOF dispatch and translator-budget release remain shared across all three forms. The delimiter search keeps native `indexOf` cursors for the next CR and LF in each decoded chunk, so scanning stays linear for every framing.

Subject: [PATCH 57/61] fix(cli): carry oocheol's CLI validation and
 diagnostics fixes (#6429 #6431 #6432 #6433 #6434 #6435 #6437 #6438) (#6447)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(cli): reject ignored capabilities arguments (carry #6429)

Carries #6429 by @oocheol onto current dev as part of the oocheol CLI batch.

Co-authored-by: 정우철 <oocheol@naver.com>

* fix(cli): reject ambiguous and unsafe integer options (carry #6431)

Carries #6431 by @oocheol onto current dev as part of the oocheol CLI batch.

Co-authored-by: 정우철 <oocheol@naver.com>

* fix(cli): accept UTF-8 BOM in imported config files (carry #6432)

Carries #6432 by @oocheol onto current dev as part of the oocheol CLI batch.

Co-authored-by: 정우철 <oocheol@naver.com>

* fix(cli): validate setup ports before saving config (carry #6433)

Carries #6433 by @oocheol onto current dev as part of the oocheol CLI batch.

Co-authored-by: 정우철 <oocheol@naver.com>

* fix(cli): support JSON output on the default alias command (carry #6434)

Carries #6434 by @oocheol onto current dev as part of the oocheol CLI batch.

Co-authored-by: 정우철 <oocheol@naver.com>

* feat(cli): show request IDs in human log output (carry #6435)

Carries #6435 by @oocheol onto current dev as part of the oocheol CLI batch.

Co-authored-by: 정우철 <oocheol@naver.com>

* fix(cli): return not-found for missing routing profiles (carry #6437)

Carries #6437 by @oocheol onto current dev as part of the oocheol CLI batch.

Co-authored-by: 정우철 <oocheol@naver.com>

* fix(responses): keep usable fallback upstream error messages (carry #6438)

Carries #6438 by @oocheol onto current dev as part of the oocheol CLI batch.

Co-authored-by: 정우철 <oocheol@naver.com>

* fix(cli): ask for the setup port again instead of abandoning ocx init

Amends the #6433 carry: an invalid interactive port now reports the error and re-asks, so a typo no longer discards every earlier answer. EOF and SIGINT at the repeated prompt still cancel without saving (exit 1 / 130); the wizard tests cover all three paths.

Co-authored-by: 정우철 <oocheol@naver.com>

* test(responses): pin recovery consumers of the upstream message fallback

Follow-up to the #6438 carry: encrypted-output resend and quota alternate-account detection now see a fallback message hidden behind a blank primary one; a nonblank primary still wins.

Co-authored-by: 정우철 <oocheol@naver.com>

* docs(cli): separate the carried reference sections

Co-authored-by: 정우철 <oocheol@naver.com>

* chore: keep the lane plan record out of the carry

 일반 도움말에는 두 개의 디스패치 대상이 의도적으로 빠져 있습니다. `__refresh-version [preview]`는 분리된 프로세스에서 업데이트 알림 캐시를 새로 고치고, `__gui-update-worker <job-id> [latest|preview] [restart]`는 대시보드 업데이트 작업을 실행합니다. 이들은 구현 세부 사항일 뿐이며 안정적인 사용자 명령이 아닙니다. 대시보드는 worker PID를 기록하고, worker가 죽은 활성 작업은 복구하며, PID가 없는 오래된 활성 기록은 10분 뒤 오래된 것으로 취급하고, 살아 있는 worker를 동시 업데이트로부터 보호합니다.

+## Capability argument validation
+
+`ocx capabilities`는 알 수 없는 인수, 반복된 플래그, 빈 `--route` 값을 종료 코드 64로 거부합니다. 유효한 경로에 등록된 기능이 없으면 종료 코드 4를 반환합니다.
+
+## Integer option values
+
+`--limit` 같은 정수 옵션은 안전하게 표현 가능한 십진 정수를 받습니다. `1_000`, `1,000` 같은 숫자 구분자는 허용합니다. 빈 값, 16진수, 지수 표기 및 소수는 요청을 보내기 전에 거부합니다.
+
+## Windows JSON configuration files
+
+`ocx config validate <file>`과 `ocx config import <file> --yes`는 선행 BOM이 있는 UTF-8 JSON도 읽습니다. 표준 입력(`-`)에도 적용되므로 Windows PowerShell이나 편집기의 UTF-8 내보내기를 사용할 수 있습니다. UTF-16은 지원하지 않습니다.

+`ocx alias --json`은 `ocx alias list --json`과 같습니다. `--json`은 명시한 alias 작업의 앞이나 뒤에 둘 수 있습니다.

 `ocx usage` reads the connected hub with this client's enrolled data key. Human output identifies the hub source and client-key scope; `--json` returns the same scoped data. Range, surface, provider/model filters and custom `--since`/`--until` bounds remain available. Account breakdowns and other clients' records are not shared. An old or unavailable hub produces an explicit error instead of substituting local usage; upgrade the hub if it does not support this read.
 
 The read-only data-plane endpoint is `GET /v1/usage`, using `x-opencodex-api-key` with a configured client key. Environment-wide and admin keys are refused. It accepts `range`, `surface`, `provider`, `model`, `since`, and `until`; unknown/repeated options and caller-selected key IDs are rejected. Oversized skipped rows retain the explicit incomplete-history warning.
+
+## Explain a listed request
+
+Human `ocx logs` output includes `id=<request-id>`. Pass that value to `ocx logs explain <request-id>` to inspect routing decisions. Rows without an ID or with control characters in their ID omit the field instead of displaying a different lookup key. JSON and JSONL output retain their existing schema.

 ## Remote Hub client lifecycle
 
 Use `ocx connect <url> --pairing-code-stdin`, `ocx connect status`, `ocx sync`, and `ocx connect rotate --pairing-code-stdin`. The initial catalog download fails after five seconds without incoming bytes, but active transfers may run longer; use `--catalog-timeout <seconds>` (1–120) to override that inactivity window. `ocx disconnect` restores local state offline and does not revoke the hub key. While connected only, `ocx connect revoke --admin-token-stdin` revokes the persisted `apiKeyId`; after disconnect use the hub's **Integrations → API Keys** page. Secrets are stdin-only and never belong in argv.
+
+## Setup port validation
+
+`ocx init` accepts TCP ports 1–65535 as decimal whole numbers. Press Enter to use 10100. Invalid input such as `0`, `10100oops` or `1.5` is never silently replaced or truncated; setup reports it and asks for the port again.

 ## CLI readiness diagnostics
 
-Catalog-derived reasoning-level diagnostics are escaped only at the human-output boundary, which `src/cli/runtime-api.ts` owns alongside the human/JSON print split. Every CLI path that prints a hub-supplied catalog value renders it there: the first-time refusal in `src/cli/connect.ts` and the connected `ocx sync` refusal in `src/cli/dispatch.ts`. C0/C1 controls, DEL, and Unicode line/paragraph separators print as visible hexadecimal escapes; structured status retains the exact reason, and a rendered failure keeps the domain error as its `cause`. The ready/unverified/incompatible classification and exit policy are unchanged.

 ## CLI resolve and stop contracts for embedding shells
 
-`ocx resolve` (`src/cli/resolve.ts`) is the machine surface a desktop shell asks instead of resolving the config home, the port, and liveness itself: the home comes from `src/config/paths.ts`, the effective port is the live listener's when the identity-checked `findLiveProxy` answers and the configured `config.port ?? 10100` otherwise, and the liveness verdict is that same module's output (pid, runtime-versus-config provenance, version, role). Config reads go through `readConfigDiagnostics`, not `loadConfig`: a missing file is defaults, but an invalid file exits 1 instead of being repaired to defaults, because a defaulted port is a guess the caller must refuse. Liveness is three-valued: when `findLiveProxy` returns null, resolve re-asks the endpoints with the updater's tri-state probe (`endpointsToProve` + `everyEndpointProvenDown` + `probeProxyLiveness`), and only a unanimous definitive "dead" becomes `absent-proven`; unknown exits 1 and never authorises a start. Discovery borrows `START_OWNERSHIP_LIVENESS`, the start path's ownership budget — the verdict feeds the shell's launch decision, so the cost of a false "nobody listening" is the duplicate proxy (#5004). The verb is in `skipsCodexShimAutoRestore`, so a read-only lookup never triggers a shim repair. Arguments are pre-parsed in `src/cli/root.ts` and exit 64 before any preflight side effect, the same ordering `ocx ready` obeys. `ocx-resolve/1` also reports `ownership` (`none`, `owned`, or `unknown`) and `takeover` (`supported` with protocol version, minimum CLI version and compatibility token, or `blocked` with a reason). A known liveness verdict still exits 0 when ownership is unknown, but takeover is blocked. An unreadable second service-state read blocks takeover instead of becoming an absent registration. `src/service/managing-cli.ts` observes the registered and selected PATH CLIs, including Windows PATHEXT order and file validation, before compatibility is offered. A `--version` probe is retried once on Windows — one transient failure must not read as an unobservable CLI — and a Windows `.CMD`/`.BAT` shim is invoked through a single verbatim-quoted `cmd /c` line, so a spaced executable path and spaced arguments both survive cmd's re-parse.

 `ocx stop --json` is a reporting layer over the unchanged stop path. `src/cli/index.ts` threads a `StopRunRecord` through the existing receipt, drain, respawn-verification and restore flow, and `src/cli/stop-report.ts` maps the recorded facts plus the signals that already pick the exit code into one versioned document (`schema: "ocx-stop/1"`). With `--json` the human lines print on stderr and stdout carries only that document; exit codes 0/1/79/80 cross the process boundary unchanged. The desktop's opt-in guarded stop adds exact approved PID, endpoint, home, CLI version and compatibility-token expectations; plain `ocx stop` retains its ordinary behavior. Under the ownership mutation lease, `src/cli/stop-approval.ts` re-resolves them and `src/service/guarded-manager-target.ts` binds any installed manager's process tree to the approved PID before a stop action. A pre-action mismatch returns `approval-changed` without stopping, and the summary carries `detail` naming the single guard fact that failed — live PID/port/hostname/CLI drift, an unverifiable ownership claim, a blocked takeover, or the compatibility fingerprint — so a transient re-probe can be told from genuine drift in the caller's log. Immediately before any manager stop or direct PID signal, the CLI rechecks the same manager identity or proven absence; a change also returns `approval-changed`. A non-OpenCodex process replacing the OS job in the remaining instant before the manager command is a residual same-user risk outside the ownership lease. The guarded path stops the bound manager, or the approved PID directly when managers are proven absent, then uses a five-second shared deadline to verify PID exit, port availability and definitive endpoint absence. Only after settlement does a read-only manager probe require launchd `not-loaded` in both domains or systemd `inactive` with `MainPID=0`; the state is checked again before a success summary. Timeout, active or unreadable manager state returns terminal `manager-still-active`, even if the endpoint briefly refuses. Windows managers bind through `src/service/windows-guarded-manager.ts`: a Task Scheduler backend must prove a recognized OpenCodex registration against the bounded current-user SID/name lookup, a running task, and a wrapper ancestor carrying this home's canonical paths — presence and running state are read root-folder-scoped because every `/tn` operation resolves a bare name there and nowhere else, so a same-named task inside a task folder is a different registration neither the probe nor the stop can reach; the registered definition itself is read only on the running path, and a state or registration read that cannot answer re-probes presence so a task deleted between probes — which can respawn nothing — reads absent while a merely unreadable one stays unknown; an unreadable current identity leaves the manager unknown; a WinSW backend must prove this installation's binary and SCM service PID ancestry; either marks `childNeedsSeparateStop`, so the approved PID receives its own graceful signal only after a successful manager stop because `schtasks /end` does not reliably cascade to the wrapper's child (#764); a failed or unknown manager stop leaves the child untouched. Post-stop Windows inactivity means the task not running, no surviving wrapper process, and no started WinSW — never mere registration presence; a running-state read that cannot answer re-probes presence the same way, so a task deleted between probes reports inactive while a persisting one stays unknown. Every Windows manager command a verdict or stop depends on — schtasks, sc.exe, WinSW verbs — runs under a bounded `execFileSync` timeout so a wedged Task Scheduler or Service Control Manager cannot hang the guarded stop; a killed command classifies through the same fail-closed paths a nonzero exit would (the interactive `install /p` password prompt is the one deliberate exception). A `wscript.exe`, `cscript.exe` or `cmd.exe` whose command line CIM cannot read makes the state unprovable only when it is tied to the proxy: pre-stop, as an ancestor of the approved PID; post-stop, as the former bound manager process or a descendant of it. Unrelated unreadable shells, which a non-admin query returns for other users' and elevated processes, are not evidence either way. An unprovable Windows manager still blocks guarded takeover. The token checks snapshot consistency, not whether a person approved the desktop prompt. `src/cli/stop-restore.ts` owns the shared Codex/Grok restoration and its history-only, history-deferred, and other failure categories.

Subject: [PATCH 58/61] feat(codex): switch accounts at 100% by default and
 make spending ChatGPT credits opt-in (#6444)

An account at 100% of a usage window is now switched out by default and returns after its reset; spending ChatGPT credits is opt-in through creditCodexAccountIds. The Codex Auth header has one global "Use credits" switch beside the credits display, and each account's switch lives in its card's more menu. Refines #6422 and closes #6334.

 In **Codex Set → Multi-auth**, enable the **Codex credits** switch in the **Codex Auth** header to display each main and pool account’s latest observed credits directly below Week. It is off by default and persists as `showCodexCredits`. The balance is a locale-formatted number, with Unlimited or an overage warning when reported; the bar indicates availability, not a percentage, because no total credit limit is supplied. Hiding credits changes display only, and a new login waits for its own observation.
 
+When an account reaches 100% on a usage window and still holds credits, upstream keeps serving it and draws the balance. OpenCodex does not let that happen by default: an account at 100% is switched out while its weekly or monthly window (only monthly on 30-day plans) or its 5-hour window is full, and used again once that window resets. The order of the other accounts does not change, and when no other account is available, selection finds none rather than spending credits. A request for the main account is refused like a hard-lock refusal until the reset. A full 5-hour window without a reset time holds an account only while that reading is fresh. Allowing the main account does not lift its hard lock (on by default at 98%), which still stops it first; turn the lock off if the main account should spend credits (a lock at 100% still stops it at 100%). To let accounts keep working from their credits, turn on **Use credits** next to the **Codex credits** switch in the Codex Auth header. The switch allows every account. To choose accounts one by one, open an account card's **⋯** menu and use **Use credits after limit** there; the header switch shows a middle position when only some accounts are on. An account allowed to spend carries a **Uses credits** badge on its card. New accounts start off. The choice is stored in `creditCodexAccountIds` and never redeems reset credits; the **Codex credits** display switch only shows balances and never changes routing.
+
 Background revalidation is separate and off by default. It requires Token Guardian, the `openai` provider's `proactive` refresh policy, and `tokenGuardian.codexWarmupEnabled`. It skips accounts awaiting deferred registration validation.

Listing `__main__` does not lift the main-account hard lock (on by default at 98%), which still stops the main login first; turn the lock off to let the main account spend credits (a lock at 100% still stops it at 100%). New accounts start unlisted. Managed by the **Use credits** switch in the Codex Auth header and the **Use credits after limit** switch in each account card's **⋯** menu. |
 | `codexQuotaAutoRefresh?` | `Record<string, object>` | `{}` | Per-Codex-login-account opt-in for automatic `fiveHour` and `weekly` window activation in Pool mode; Direct mode does not run this worker. In Providers/Codex Auth **Advanced settings**, one control enables or disables both supported windows across all current main and added accounts. New accounts are not opted in automatically. Enable skips windows absent from live WHAM data; disable also clears stale enabled windows. The UI reuses granular `/api/settings` writes, reconciles partial failures, and retries the original ON/OFF intent without replacing unrelated settings or completed reset markers. The API still rejects enabling an unavailable window with HTTP 409. At a reported reset time, opencodex sends one minimal non-stored Codex message using that account's quota and persists the activated timestamp. This does not apply to API-key providers. |
 | `codexAccountNamespaces?` | `Record<string, string>` | — | Optional map from an arbitrary public model selector to a stored Codex account target. When account-qualified picker rows are enabled, each selector whose target is present adds separate `<selector>/<native-openai-model>` rows to the Codex picker; each row uses only that account. With any selector active, bare native rows are hidden in the picker, but their ids remain routable and listed by raw `/v1/models` unless explicitly disabled. |
 | `codexAccountPickerEnabled?` | `boolean` | off when the map is empty | Controls whether eligible `codexAccountNamespaces` mappings generate account-qualified Codex picker rows. `true` allows mapped rows to appear. If omitted with a non-empty map, it is treated as enabled for backward compatibility; if the map is empty, it is off. `false` hides generated rows and restores bare native picker rows without deleting mappings or disabling exact `<selector>/<native-openai-model>` routing. |

+## Credits after the usage limit
+
+Upstream keeps serving an account that holds ChatGPT credits at 100% and draws the balance, and
+selection only leaves an account on quota after a refusal, so such an account was never moved off
+(#6334). Spending is opt-in: `creditCodexAccountIds` lists the accounts, `__main__` included,
+allowed to keep serving from credits, and absence means none. Every other account is switched out
+at 100% and returns after its reset, so a new account also starts with spending off.
+`src/codex/account-credit-use.ts` owns the list and the full-window rule. An unlisted account is
+held while a usage window reads 100%: the long window (weekly, or monthly on 30-day plans) only
+while its reset is still ahead, the burst window through `isTerminalShortWindow`. A held account
+receives no traffic and therefore no new observation, so the reading has to end on its own; a long
+window without a reset is not trusted.
+
+The hold is checked wherever plan exclusion is checked in `src/codex/routing/selection.ts`: the
+eligible list (its pool filter and its main branch), `isCodexAccountSelectable`, and
+`codexAccountBlockReason`, which reports `credits_off`. `isCodexAccountRotationExcluded` carries
+both policies into the two legacy keep-the-active-account fallbacks and the transient-only affinity
+check in `src/codex/routing.ts`, so a pool whose accounts are all held selects none instead of
+spending. The main login has paths that never reach selection, so `src/codex/auth-context.ts` also
+checks it where the main-account hard lock is checked: `assertMainAccountPolicy` throws
+`CodexMainAccountCreditsOffError` (a cooldown error, mapped like the hard lock), and
+`requestOwnedMainPinState` stops preserving a caller's own main credential. Both read the main
+policy quota the lock reads and no plan, because several of those callers may not open the physical
+auth file. The two main-account policies stay separate: listing `__main__` does not lift the hard lock
+(98% by default), which refuses first, and the main card's switch says so. Both refusals are
+policy, not authentication: they keep their own message in `cooldownErrorMessage` and never mark the
+login for reauthentication, including when the window fills during the awaited token refresh.
+
+`PUT /api/codex-auth/accounts/credits` writes one account (`{ id, creditsAfterLimit }`, pool
+accounts and `__main__`) or the whole list (`{ all }`: on lists `__main__` and every selectable
+pool account, off clears it). It has no CLI verb yet (`deferred-verb`, owner "#6334 follow-up");
+`ocx config set creditCodexAccountIds` covers scripted use. The dashboard control is
+`gui/src/components/CodexCreditSpend.tsx`: one global switch in the Codex Auth header beside the
+"Codex credits" display switch, derived from the rows (off when none may spend, mixed when some
+may, on when all may, matching the quota auto-refresh control), and one switch per account inside
+that card's "⋯" disclosure (the main card gets the same disclosure for it). Clicking the global
+switch from off or mixed allows every account; from on it clears them all. `CreditsOnBadge`
+marks an account allowed to spend, independent of the display switch, which still never changes
+routing. Coverage: `tests/codex-integration/codex-credits-after-limit.test.ts`,
+`tests/codex-integration/codex-credits-after-limit-main.test.ts` and

Subject: [PATCH 59/61] fix(service): wait out the npm Bun placeholder instead
 of executing it (#6441)

* fix(service): wait out the npm Bun placeholder instead of executing it

- The Windows service wrapper now applies the shared REAL_BUN_MIN_BYTES rule before launching Bun; during an in-place npm install it logs and retries every 5s until bun's postinstall replaces the placeholder, instead of exiting 216 behind a modal 16-bit dialog

* fix(service): keep waiting when Bun vanishes between the exist check and the size read

- An empty OCX_BUN_BYTES made the size comparison a cmd syntax error that ended the wrapper; the read now resets the value and treats an unset size as not ready

- The wait message names a persistent placeholder's remedy

* docs(service): describe the Windows service wrapper builder

- buildWindowsServiceScript names what the generated batch wrapper does, answering the CodeRabbit docstring check

* docs(structure): record the Windows wrapper's wait on the npm Bun placeholder

- docs-and-release and runtime state that the wrapper re-checks a placeholder or vanished Bun every five seconds, that a Bun path missing at the exist check keeps the bun_missing exit, and how a permanently blocked postinstall recovers

 The scheduler wrapper retries child exits, including zero, after five seconds. Only the
 opt-in CLI stay-out code ends it successfully; missing Bun/CLI paths still exit with
 installation error 3. Explicit service stop terminates the wrapper itself.
+Before launching, the wrapper applies the bundled-Bun size gate (`REAL_BUN_MIN_BYTES`). An
+in-place npm install extracts `bun/bin/bun.exe` as a small placeholder and replaces it only when
+bun's postinstall runs later; executing the placeholder exits 216 and, interactively, raises a
+modal 16-bit dialog. A Bun file below the gate, or one whose size cannot be read because it
+vanished after the exist check, logs `bundled Bun is not ready` and is re-checked every five
+seconds without being executed, so the service starts once the postinstall lands. A Bun path
+that is already missing at the exist check keeps the unchanged `bun_missing` path: backup
+restore, then installation error 3. If the postinstall never runs (scripts blocked), the
+wrapper keeps waiting and logging; reinstalling with `--allow-scripts=bun` (or running the
+package's `bun/install.js`) is the recovery, and the next pass starts without a service repair.
 Timestamp expansion in the scheduler wrapper stays outside parenthesized batch
 blocks so locale dates containing parentheses cannot abort prelaunch checks or

Subject: [PATCH 60/61] feat(providers): add OpenGateway (Sionic AI) preset
 with live discovery and Sionic-first ordering (#6448)

* feat(providers): add OpenGateway (Sionic AI) preset with live discovery and Sionic-first ordering

* fix(opengateway): read preferFirst from captured gather policy, register test layout, add provider mark

- routed-gather read the live registry after capture (codex-gather-authority); the
  ordering decision now comes from the captured discovery spec, and preferFirst is part
  of the captured discovery-policy snapshot.
- register tests/providers/opengateway-provider.test.ts in the test layout map and
  its expected fixture.
- add OpenGateway's header mark (opengateway.ai/logo.svg, byte for byte), masked,
  wired in the GUI and desktop shell; the favicon was rejected for a <text> glyph.

* fix(opengateway): mark public catalog non-validating, admit only rows served on their wire

- apiKeyValidation: "unknown": GET /v1/models answers 200 for any Bearer, so it
  cannot prove a key (Codex review P2).
- discovery admits active chat_completions rows plus the Responses-only rows pinned to
  Responses (openai/o3-pro); a future Responses-only row stays hidden instead of
  being published on the Chat default and 404ing (CodeRabbit major). Live: still 70
  admitted, Sionic rows first.
- docs/structure wording follows the new filter in all locales.

* fix(opengateway): keep a custom replacement in its preferred slot; pin derived non-validating key login

A custom model that replaces a discovered row of a provider whose discovery declares an order
(preferFirst) now takes that row's slot instead of moving to the end of the list. Providers without
preferFirst keep the previous order: discovered rows first, custom rows after.

Also pins that the derived OpenGateway key-login entry keeps apiKeyValidation "unknown" and that
validation never probes the public catalog.

 `src/codex/catalog/model-visibility.ts` excludes disabled providers, including custom rows. `src/codex/catalog/gather-capture.ts` leaves disabled providers and every `adapter: "jev-decision"` decision-service row out of the gather flight, so a decision row's `defaultModel` or `models` never becomes a routable catalog row and its endpoint is never probed for `/models`. `src/codex/catalog/routed-gather.ts` does not inherit their configuration into custom rows. HTTP discovery, startup/explicit sync (`src/codex/catalog/retained-sync.ts`), and client exports (`src/server/management/model-rows.ts`) apply new-model policy before publication. `src/providers/new-model-policy-runtime.ts` commits authoritative arrivals and automatic disables together under the config mutation lock, without rewriting an unchanged roster. It rechecks provider inventory and cache revisions and refuses publication on failed persistence. Retained sync reconciles after catalog evidence revalidation, preserving K-to-C lock order. Exports recapture their snapshot after committing discovery; superseded gathers only project policy onto a detached copy and retain no preview. Supplied rosters and read-only previews do not reconcile. Synthetic configurations only project their own state. File-backed configs retain their load provenance when their inventory diverges from disk. Read callers can opt into a detached policy projection when drift predates discovery: management renders its disabled rows, while other shared-fetch consumers receive only its visible rows. The projection copies discovery state and disables, leaving live config, disk, and the live merge baseline untouched. Writer callers still refuse stale publication; reload or explicit adoption is required before retained sync can commit. Inventory changes during discovery, superseded cache revisions, changed config homes, and failed persistence still refuse publication. Discovery absorbs arrivals/reappearances without advancing removal grace; convergence retains removal accounting. Bootstrap, custom rows, explicit selections, and degraded discovery retain the pure policy rules. Coverage: `tests/server/server-new-model-policy-arrival.test.ts` (HTTP), `tests/codex-integration/codex-sync-new-model-policy.test.ts` (startup/sync), `tests/server/model-export-new-model-policy.test.ts` (exports/previews), and `tests/providers/new-model-policy-runtime.test.ts` (persistence/concurrency), and `tests/codex-integration/model-visibility-management-api.test.ts` (drifted read projection).
 
+Custom rows replace discovered rows that encode to the same Codex-facing slug. For a provider whose captured discovery declares an order (`preferFirst`), `src/codex/catalog/routed-gather.ts` puts the replacement in the discovered row's slot; every other provider keeps discovered rows first and custom rows after them, as before. Coverage: `tests/codex-integration/catalog-custom-ordering.test.ts`.

 On the default `opencodex-catalog.json` path, sync deliberately uses two catalog sources: Codex's
 bundled catalog supplies a current native entry template, while the actual on-disk catalog supplies
 the rows being merged. This split is required because empty or partial provider discovery must
