Summary

  • injectCodexConfig() never reconciled Codex''''''''''''''''''''''''''''''''s global features.multi_agent_v2 override. Codex resolves that override before catalog-level multi_agent_version pins, so a fresh OpenCodex install — which writes multiAgentMode: "v1" — on a Codex home that had previously enabled v2 produced an internally inconsistent state: the injected catalog claims v1 while new sessions actually run v2 and spawn unreadable encrypted child tasks.
  • Before the journal baseline, an injection whose config explicitly selects v1 now runs the same format-preserving transitionMultiAgentV2 used by the explicit CLI (ocx v2 mode) and API (PUT /api/v2) mode selectors to disable the global flag.
  • The reconcile lives in src/codex/inject/multi-agent-v2.ts so the inject.ts facade stays under its file-size ratchet cap; a setCodexMultiAgentV2ToggleForTests seam (same idiom as the file''''''''''''''''''''''''''''''''s existing set*ForTests hooks) lets the regression test substitute the native codex features command.
  • Validation-only injection and externally managed provider configs remain read-only and untouched.

Verification

  • Head: 7e1a386af530b849074fe70c2ff989f879efbcba (tree 468c5273929f69d3662c46866987c22d6450e801), based on dev 6467235a85df0f649a588c601532316d6ae0fce9.
  • bun test tests/codex-integration/codex-inject-integration.test.ts — 90 pass / 0 fail / 1 environment-conditional skip, including a new regression that seeds features.multi_agent_v2 = true, runs a v1 injection, and asserts the flag is reconciled to false.
  • bun x tsc --noEmit — clean.
  • bun run structure:check — passed.
  • bun run privacy:scan — passed.
  • bun scripts/file-size-ratchet.ts — passed (src/codex/inject.ts held at its 987-line cap).

Remaining gates

  • Fork CI dispatched via gh workflow run ci.yml on this branch. The macOS control job is expected to cancel at the 30-minute mark; that is the known upstream limitation tracked in [Bug]: macOS control is cancelled near its 30-minute limit in full dispatch CI #4905, not a signal from this change. Occasional shard flakes are likewise known upstream noise.
  • No gui/ files are touched, so the UI-screenshot gate does not apply.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

📝 Walkthrough

Walkthrough

Codex injection now reconciles an enabled global multi_agent_v2 feature when OpenCodex selects v1. The flow updates rawContent before later transforms, fails before writing if reconciliation fails, and preserves validation-only and disabled-integration behavior.

Changes

V1 surface reconciliation

Layer / File(s) Summary
Reconciliation logic
src/codex/inject/multi-agent-v2.ts
Adds conditional v2 detection and disabling, reloads CODEX_CONFIG_PATH after success, returns failure details when the transition fails, and provides a test toggle seam.
Injection flow integration
src/codex/inject.ts
Runs reconciliation only for eligible v1 injections, uses reconciled content for later transforms, stops before writing on failure, and updates affected outcome messages when config.toml changes.
Validation and documentation
tests/codex-integration/codex-inject-integration.test.ts, structure/config.md, structure/subagents.md
Tests successful v1 reconciliation and skipped injection behavior. Documentation describes the reconciliation and read-only conditions.

CodeRabbit Major finding (pre-gate ordering for the v1-surface reconcile) is fixed in 7e1a386af:

  • injectCodexConfigImpl now evaluates the integration-toggle skip and beforeClientWrite guard before reconcileInjectedV1Surface may persist its config.toml transition, so a skipped/refused v1 injection can no longer leave the file changed while reporting that nothing changed.
  • For the residual post-reconcile refusal paths (ambiguous native-defaults baseline, unverified journal baseline, lock outcome), the messages are now reconcile-aware and state that the v1-surface reconcile was applied instead of repeating the stock "nothing changed" clause.
  • reconcileInjectedV1Surface now reports changed, and a new regression test covers that a skipped v1 injection does not run the v2 reconcile or leave the file changed.

Local gates: bun x tsc --noEmit, bun run structure:check, bun run privacy:scan, and bun test ./tests/codex-integration/codex-inject-integration.test.ts (91 pass, 1 skip, 0 fail).

Requesting changes on exact head 69193753e07c010ff8f63c5490008968d96789bc.

The v1/v2 consistency problem is real, but the reconcile is currently outside the write transaction that makes Codex injection safe:

  • reconcileInjectedV1Surface() invokes the native codex features disable mutation before withCodexWriteLock() is acquired in injectCodexConfigImpl.
  • A later ambiguous-baseline, unverified-journal, or lock failure now leaves config.toml changed while the rest of the injection fails. Making the message truthful does not restore atomicity.
  • Another injection/restore/native feature command can modify the same file between the reconcile, the re-read, and the eventual injection lock. The pre-check of beforeClientWrite is not mutual exclusion and does not close that race.

Move the feature transition into the same coordinated Codex write boundary as the injection, with one verified preimage and rollback/compensation if any later step refuses. The regression needs to prove both: (1) a post-reconcile failure restores the exact original bytes, and (2) a competing writer cannot land between the feature transition and the injection commit. Do not merely expand the reconcile-aware status messages.

This branch also predates current dev and has no hosted Cross-platform CI on the current head. Rebase after fixing the transaction boundary and obtain green exact-head CI before re-requesting review.

Holding this at the merge gate. I run a preflight before merging now — build the merge-result tree with git merge-tree --write-tree origin/dev <head> and evaluate the file-size ratchet against that tree rather than against the branch alone. This change comes back with two offenders:

src/codex/inject.ts                                     1036 lines  GREW  cap=987
tests/codex-integration/codex-inject-integration.test.ts 2000 lines  NEW_OVERSIZED

Neither shows up on your branch's own CI, because the cap comparison only bites in the merged tree. That is the class of failure that broke dev five times before this preflight existed, so it is not something I can wave through and repair afterwards.

The second one is almost free: NEW_OVERSIZED triggers at 2000 lines or more and the file lands at exactly 2000, so one line under the threshold clears it. The honest way to get there is to move the new cases into a sibling file rather than to squeeze a line out, and a sibling needs registering in both scripts/test-layout/layout.json (explicit) and tests/fixtures/test-layout-expected.jsontests/test-layout-tooling.test.ts names whichever one is missing.

src/codex/inject.ts is the harder half at 49 lines over. Raising the cap is not available: updateBaseline only lowers, and tests/ci-workflows/file-size-ratchet.test.ts asserts it. Trimming the comments this change adds would fit the budget and is the wrong trade — the block explaining why the write gates are evaluated before the v1-surface reconcile may run is doing real work, since that ordering is the whole reason a skip cannot leave the file changed while reporting no change. An extraction is the right shape; reconcileInjectedV1Surface and its call-site preamble look like a seam that could live beside inject/multi-agent-v2.ts rather than inside inject.ts.

The change itself reads well and I would like to land it. Ping here once it is split and I will re-run the preflight and merge. I have not run anything locally against this branch.

Rework is pushed at 960a4a9 (reconcile now runs inside the write lock; the oversized inject.ts was split into src/codex/inject/* modules).

One note for review: the .github/workflows/ci.yml hunk is a one-line fix paired with desktop/src-tauri/tauri.conf.json — the new mainBinaryName makes the unsigned desktop build produce updater artifacts, so the CI step now passes --config '{"bundle":{"createUpdaterArtifacts":false}}'. It trips the unsponsored_surface hygiene gate by design; this PR needs maintainer-sponsored when a maintainer has reviewed the workflow line.

@Ingwannu re-review requested when convenient.

All four readiness items are now met: CI is green at head fd79760, the branch is within 10 commits of dev, and the outstanding CodeRabbit finding (v1-surface reconcile ordering) was fixed in 8b6a596 — the reconcile now runs inside the write lock after the admission gates. The readiness checklist is ticked. Ready for review — the draft flag still needs a maintainer since ready-for-review is permission-gated for the fork author. cc @lidge-jun

Codex resolves the global features.multi_agent_v2 override before catalog-level multi_agent_version pins. injectCodexConfig() never reconciled it, so a fresh OpenCodex install (multiAgentMode: v1) on a Codex home that had previously enabled v2 produced a catalog claiming v1 while new sessions actually ran v2 and spawned unreadable encrypted child tasks. The explicit mode selectors (ocx v2 mode, PUT /api/v2) already run the format-preserving transition; the injection path now does the same before taking the journal baseline.

The reconcile lives in src/codex/inject/multi-agent-v2.ts so the inject.ts facade stays under its file-size ratchet cap. Validation-only injection and externally managed provider configs remain read-only.
The reconcile ran before withCodexWriteLock, so a later ambiguous-baseline, journal, or lock refusal left config.toml changed while the injection failed, and a competing writer could land between the transition and the commit. The feature transition now runs inside the coordinated write boundary: one preimage captured under the lock covers it and the artifact commit, and any later refusal restores the exact original bytes, flag included. The committed bytes are re-derived from the post-transition input so the injection cannot re-enable the flag it just turned off.

The derivation pipeline moves to inject/plan.ts so inject.ts stays under its file-size ratchet cap, and the reconcile tests move to codex-inject-v1-reconcile.test.ts for the same reason. New regressions prove a post-reconcile failure restores byte-exact config and feature state, and that a competing writer is serialized out between the transition and the commit.

The widget job runs 'tauri build' without TAURI_SIGNING_PRIVATE_KEY, but
bundle.createUpdaterArtifacts is enabled so the bundler tries to sign the
.app.tar.gz updater archive and the job fails after a green build.

Pass --config to disable updater artifacts in the unsigned CI build only;
release.yml still produces signed updater artifacts. Also set
mainBinaryName so the in-bundle binary is Contents/MacOS/OpenCodex (Tauri
v2 defaults to the Cargo package name), which the verify step asserts.

…-ledger lease

The probe-hardening file fakes the trusted System32 directory for its schtasks
and sc.exe fixtures. Since lidge-jun#5157, startServer first acquires the shared
spend-ledger lease, which hardens the state directory through the trusted
icacls.exe/powershell.exe resolution — the fake directory shadows both, so the
principal lookup dies EACLIDENTITY before the ownership probe runs and the
`one startup keeps two targeted queries` case fails on the Windows leg.

Pin the icacls and principal runners for the file (the lidge-jun#3258 hermetic-ACL
convention); the seams are inert for the tests that never start a server.

…discovery fetches

The four tests that write a main auth.json race startServer's asynchronous
startup-gate convergence: while the snapshot is still recovery-pending,
withNativeMainCredentialAdmission excludes __main__ by design, so the
roster fetch never runs and askedVersions stays empty / the selector row
never appears. The window is usually won locally; on the loaded Windows
shard (run 35534280700, windows 6/9) all three entitlement-dependent
assertions lost it.

Wait on waitForNativeMainStartupGate — the same seam
codex-envkey-admission-substitution uses for this flake class — before
the first request.

…e removing the test home

Windows shard 7/9 timed out: once the first fire-and-forget stop left the
spend-ledger lease and config-dir icacls flight pending, removeTreeWithRetry's
synchronous sleeps starved the teardown that closes them, so every later hook
re-failed EBUSY on the same fixed TEST_DIR. Await each stop, give the file a
per-test mkdtemp home, and drain the harden flights, icacls reaps, and
native-main startup releases in afterEach — the removal-barrier sequence
server-management-auth.test.ts already documents for this Windows contract.

Superseded by #5609, which is open and not yet merged. The v1 injection reconcile (96dcf81, ab917f3, 487c1cf) is reimplemented there once, crediting you as co-author. It also repairs two things: the coordinator witness now covers the bytes actually committed after the v1 path rederives the plan, and the native toggle is resolved before the lock, with no synchronous require. The Devin CI follow-ups are not carried. fefd175 and the fixture change in 9aeac79 are already on dev in equivalent form (6c2f767). 9a0ba20, ab9f2bc and ce6b978 are dropped because dev covers those failures differently (6c2f767, 798c07c). Thank you!
