feat(memory): route Codex memory phases to a chosen model

[robin-bially]

Summary

Codex writes memories in two background phases, and each phase asks for its own bare native model, so on a routed setup both land on the OpenAI account while ordinary traffic runs on a configured provider. This adds a memoryModels setting with one entry per phase — extract (one summary per finished session) and consolidation (the agent run that merges those summaries into $CODEX_HOME/memories) — each holding a model and an optional reasoningEffort, plus a Memory routing panel in Dashboard → Overview that edits it.

The phases are recognized from Codex's own turn metadata, never from the model id: request_kind: "memory" in x-codex-turn-metadata marks an extract pass, and thread_source: "memory_consolidation" marks the consolidation thread; on HTTP the x-openai-subagent: memory_consolidation header names a consolidation pass on its own. WebSocket frames decide from the per-frame metadata only. The model id is deliberately not a signal, because extract runs on the same helper model Codex uses for titles and commit messages — a model-based rule would also capture ordinary helper calls. Missing, malformed, or conflicting metadata does not activate the override, and WebSocket requests read each frame's metadata rather than the connection's handshake.

A configured phase wins when shadowCallIntercept matches the same request; a phase left off keeps its current routing, which includes the intercept, and both phases now run on default intercept source models: gpt-5.6-terra, the model Codex asks for the consolidation pass, joins gpt-6-luna/gpt-5.6-luna in that list, so an enabled intercept covers the whole memory pipeline. A target that stopped resolving fails that memory call with 409 and code memory_model_target_unavailable instead of falling back to the native model the operator routed away from. The request log names the phase (memory-extract, memory-consolidation) as the routing reason.

The ⓘ next to the title explains both phases in the panel itself:

Verification

Everything below ran on the rebased head cd45810fa unless a bullet says otherwise.

• bun run typecheck and bun run lint:gui — clean.
• bun test tests/responses/responses-memory-models.test.ts — 19 pass, 0 fail: phase detection from both metadata copies and from the sub-agent header alone (HTTP only now), WebSocket frames deciding per frame, rejection of conflicting or malformed metadata, config validation with per-phase degrade and the load-time warnings (a broken phase, a misspelled phase key, and silence for a valid or absent block), per-phase routing and effort in both wire shapes, shadow-intercept precedence, combo handoff, the unavailable-target response, and the admission refusal on the memory target.
• Codex asks gpt-5.6-terra for the background memory-consolidation pass, which is helper traffic by role, so gpt-5.6-terra joins the default shadow source models. With the previous list only phase 1 was covered, because it runs on the gpt-5.6-luna/gpt-6-luna helper slug, and phase 2 stayed on the native account the operator routed away from. tests/responses/responses-shadow-intercept.test.ts now asserts the terra rewrite, including for a turn tagged x-openai-subagent: memory_consolidation; the assertion that called terra a non-helper model came from the source-model-set change (issue Shadow call intercept no longer matches Codex 0.145.0 shadow model (gpt-5.6-luna) #311), where it was one example alongside gpt-5.5 and gpt-5.6-sol rather than a statement about its role. The GUI fallback, the config type docs, the structure map and the configuration docs in every locale follow the list.
• bun test tests/config/settings-memory-models.test.ts — 4 pass, 0 fail: the settings round trip, including that a successful PUT /api/settings echoes the saved memoryModels block (the panel re-reads the response of its own save), that null clears the block from the file, and that a malformed phase is rejected before any mutation.
• bun test ./gui/tests/memory-models-panel.test.tsx — 2 pass, 0 fail: the account notice appears exactly while one phase is routed, and the per-phase save round-trip including effort clearing with its model.
• bun test tests/test-layout.test.ts tests/test-layout-tooling.test.ts tests/ci-workflows/file-size-ratchet.test.ts — 27 pass, 0 fail.
• cd gui && bun test tests — 2590 pass, 0 fail across 300 files. This is the GUI package's own suite, which bun run test does not include.
• Full suite (bun run test, clean checkout outside the agent home) — the parallel lane ran 32720 tests across 1805 files in 326.9 s and ended with four failures in two files, both environment-only and both green in isolation at this head. tests/service/shutdown-launcher.test.ts (SIGINT, SIGTERM, SIGHUP) times out at 20 s each because a live proxy already owns client routing on port 10100, so the spawned launcher refuses to inject the Codex config: 0 pass, 3 fail, 60.6 s in isolation, and the three fail identically at the dev tip 429f4e017 with this branch absent. tests/codex-integration/native-codex-toggle.test.ts passes 13/13 in isolation at this head. An earlier run of the same suite, with the GUI suite running concurrently, also reddened tests/claude-integration/claude-models-discovery.test.ts (13/13 in isolation) — load-sensitive, like the eight extra failures a control run at an earlier dev tip produced without this change set. None of them is attributable to this change.
• Executable CI on 74079a023, the head before the React Doctor fix, with the runs approved by a maintainer: Cross-platform CI passed every job - test 1/4 through 4/4 (5m08s, 7m10s, 6m55s, 6m27s), desktop shell (10m57s), gates, docker smoke, api usage, storage policy, keyring on ubuntu and windows, npm-global on ubuntu and windows, and the docs site build. React Doctor failed on a single warning in this branch's own code: prefer-module-scope-pure-function at gui/src/components/MemoryModelsPanel.tsx:94, where the phase-payload helper was declared inside the render body instead of at module scope. bcddef6a3 hoists it, and react-doctor --scope changed --base e2ae5f2dc --blocking warning reports "No issues found" (score 100/100) over the 16 files this PR changes at the current head. The Cross-platform CI and React Doctor runs for bcddef6a3 stayed action_required for four hours and never executed, and the runs for the current head cd45810fa will need the same approval: a fork PR needs a maintainer to approve each new run, which the author cannot do.
• bun run build:gui — built; bun run privacy:scan — pass.
• Evidence for the five scenarios named in the approval hold, each pointing at the test that asserts it:
  • metadata disagreement — tests/responses/responses-memory-models.test.ts: "conflicting copies are not treated as a memory turn", "both copies must agree on the same phase", "an ordinary turn, absent metadata, or malformed metadata is never a memory turn".
  • per-frame WebSocket classification — same file: "WebSocket frames read the body copy instead of the handshake header", "the connection's sub-agent header consolidates HTTP turns but not websocket frames".
  • combo failover — same file: "the phase decision survives the combo handoff" (the phase's effort reaches the combo child, and the rewritten selector is what the log records).
  • admission denial — same file: "an admission denial on the memory target keeps the key's own refusal": a scoped key whose provider list excludes the memory target gets 403 model_not_allowed_for_key and nothing is sent. The memory destination is resolved by the same shared resolver the shadow intercept uses (resolveChosenTarget), which rethrows AdmissionModelDeniedError rather than reporting the target as unavailable. That case is new here, because nothing covered it before.
  • unavailable targets — same file: "a target that no longer resolves fails the memory call instead of falling back" (409, memory_model_target_unavailable, no send), plus the existing lifecycle cases in tests/responses/shadow-intercept-target-lifecycle.test.ts that cover the shared resolver through the shadow surface.
• The branch sits on the dev tip e2ae5f2dc (4 commits behind, inside the readiness check's 10-commit tolerance). The rebase onto it replayed the then-twelve commits patch-identically and without a conflict, so the only difference to the pre-rebase head was the base; the thirteenth commit is the shadow-source change described below. The diff against dev stays purely additive (51 files, +1543/−69).
• The layout map needs no change: tests/responses/responses-memory-models.test.ts is placed by the responses- domain seed and tests/config/settings-memory-models.test.ts by the settings- seed, the path the layout tooling test documents for a conventionally named file, so scripts/test-layout/layout.json and tests/fixtures/test-layout-expected.json stay byte-identical to dev.
• cd gui && bun test tests also found a real one: gui/tests/fr-localization.test.ts rejects a French value identical to its English source, and memoryModels.consolidation was that shape. "Consolidation" is the ordinary French noun, so the key joins that test's allowlist for correct French words spelled as in English; renaming it would also break the pair with the extract row, whose French label is "Extraction".
• Two CodeRabbit findings on the load-time warnings, both fixed in 74079a023. The warning claimed a degraded phase keeps Codex's own model, which is wrong: with no configured target for the phase the request is an ordinary turn again, so shadow-call interception can still match it — both warnings now say the phase keeps its existing route, which may include shadow-call interception, the wording the panel's own notice uses. And a misspelled phase key (extrcat) was stripped by the deliberately permissive load schema without a word, so the next settings save persisted the sanitized map and dropped the hand-edited key — warnDegradedMemoryModels now reads the raw object and names every unrecognized phase, with the key name redacted and JSON-escaped the way the retryOn429 sanitizer already does it.
• Screenshots taken from a proxy started from this branch (bun run build:gui, isolated OPENCODEX_HOME, English dashboard, 16:9 window at 2.4x pixel density).
• The ⓘ next to the panel title opens a modal dialog with the shared dashboard modal classes, matching the shadow-call and effort-cap help dialogs, and it sits centred on the heading through the same display: flex; align-items: center title row those panels use (the icon centre and the text centre land 0.25 px apart, the same offset the effort-cap panel measures).

📝 Walkthrough

Walkthrough

The change adds independent model and reasoning-effort settings for Codex memory extraction and consolidation. The server validates and stores these settings, identifies memory phases from request metadata, and routes configured phases to their selected models. The dashboard provides controls for both phases.

Merge Risk: ⚪ Minimal · up to 74079

The settings retain valid phases when another phase is malformed, and the Japanese notice accurately explains routing behavior. No concrete issue remains that should block merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 74079

Memory requests can now go to an operator-selected provider. Permission checks and unavailable-target handling limit exposure, but client-supplied phase markers can select this exceptional route. The safety of simultaneous settings changes is not established.

Retained concerns

• Low · security · inferred: Caller-supplied phase markers can select memory routing over shadow interception and label an ordinary request as a memory turn. This is a routing-provenance concern, not an established admission-control bypass.

Security review details

Security Blast Radius

• inferred — For configured phases, memory-extraction or consolidation request content can reach the chosen provider instead of its previous route. Exposure is bounded to configured destinations and admitted callers; deployment-wide caller and provider scope is not established.

Security Findings and Attack Paths

• inferred — A caller able to submit Responses metadata can claim a memory phase on an ordinary turn, selecting the configured phase route ahead of shadow interception and causing a memory-phase route reason to be recorded. The reviewed admission check limits this path; no access to a prohibited provider or another caller's data was demonstrated.

Trust Boundaries and Controls

• observed — Phase identification rejects malformed or conflicting metadata copies, WebSocket phase selection excludes handshake headers, destination resolution preserves admission refusals, and an unresolved configured target fails without an upstream fallback.

Resilience and Maintainability Implications

• inferred — Strict writes, deletion on null, rollback capture, and degraded-load warnings reduce accidental persistence of an invalid route. Whether simultaneous updates can restore a stale phase choice remains unproven.

Hardening Proposals

• proposed — If exceptional memory routing must be restricted to genuine Codex memory turns, establish phase provenance at a trusted ingress rather than treating caller-supplied markers alone as proof; retain destination admission checks.

리뷰 · 우선순위 62 / 80

Codex는 세션이 끝나면 기억을 두 번 적습니다. 추출은 끝난 세션 하나를 짧게 요약합니다. 통합은 그 요약들을 모아, 다음 세션이 읽는 기억 파일에 합칩니다. 지금은 두 단계가 각자 원래 모델을 부르기 때문에, 다른 모델로 길을 돌려 둔 컴퓨터에서도 이 호출만 OpenAI 계정으로 갑니다. 추출은 제목이나 커밋 메시지를 만드는 도우미와 같은 모델 이름을 씁니다. 모델 이름만 보고 바꾸면 도우미 호출까지 같이 바뀝니다.

이 PR은 단계마다 쓸 모델과 추론 강도를 정하게 합니다. 대시보드 개요에 메모리 라우팅 칸이 생깁니다. 단계는 Codex가 요청에 붙여 보내는 표시로만 구분합니다. 추출은 request_kind: "memory"입니다. 통합은 thread_source: "memory_consolidation"입니다. 헤더 x-openai-subagent: memory_consolidation만 있어도 통합으로 봅니다. 표시가 없거나, 깨졌거나, 서로 다르면 바꾸지 않습니다. 웹소켓은 연결을 열 때의 턴 표시 헤더를 쓰지 않고, 각 프레임 안의 표시를 읽습니다. 고른 단계가 있으면 그 설정이 그림자 호출 가로채기보다 우선합니다. 끄면 지금 길을 그대로 둡니다. 고른 모델을 더 이상 찾을 수 없으면 원래 모델로 돌아가지 않고, 409 memory_model_target_unavailable를 돌려줍니다. 요청 로그에는 memory-extract 또는 memory-consolidation이 남습니다. 바탕 브랜치는 dev입니다. types.ts와 config.ts를 나누는 변경은 아닙니다.

라인 - gui/src/components/MemoryModelsPanel.tsx 176줄. 모델을 하나라도 고르면 노란 경고가 나옵니다. 그 문장 memoryModels.accountNotice는 고르지 않은 요청이 OpenAI 계정으로 간다고 말합니다. gui/src/i18n/en.ts 429줄, gui/src/i18n/ko.ts 415줄이 그 문장입니다. 둘 다 꺼 둔 화면에는 이 경고가 없습니다. 실제로 OpenAI로 가는 때에는 안내가 없고, 다른 모델을 고른 뒤에 그 안내가 뜹니다.

라인 - src/server/responses/memory-models.ts 85줄. 턴 표시가 메모리 요청이 아니라고 해도, x-openai-subagent가 memory_consolidation이면 통합으로 바꿉니다. 웹소켓은 이 헤더를 프레임마다 다시 받지 않습니다. src/server/index/websocket-handler.ts 302줄은 헤더를 연결을 열 때 한 번만 정하고, 323줄이 그 헤더를 이후 프레임에 그대로 붙입니다. 같은 감지 함수 66줄은 턴 표시 헤더만 웹소켓에서 빼 둡니다. 연결을 열 때 통합 헤더가 있으면, 표시가 없는 다음 프레임도 통합 모델로 갑니다. 열 때 그 헤더가 없으면, 나중 프레임에 헤더가 있어도 헤더만으로는 통합을 알아보지 못합니다.

라인 - src/config/schema/config-schema.ts 162줄. 손으로 고친 memoryModels가 깨지면 블록 전체가 빠집니다. 추출은 맞고 통합의 노력 값만 틀려도 추출 설정까지 사라집니다. src/config/load-degrade.ts 127줄 주석은 깨진 단계만 꺼진다고 적습니다. 134줄 경고는 기억 파이프라인 전체가 Codex 모델을 쓴다고 합니다. 관리 화면 저장은 validateConfigCandidate가 거절합니다. 이 빠짐은 설정 파일을 직접 고친 경우에 납니다.

메인테이너의 판단이 필요한 지점

계정 경고를 모델을 골랐을 때 보여줄지, 꺼 두었을 때 보여줄지 문장과 같이 정하면 됩니다. 웹소켓의 서브에이전트 헤더를 턴 표시처럼 프레임 안에서만 볼지 정하면 됩니다. 한 단계의 오타가 다른 단계까지 지울지 정하면 됩니다. 이 PR은 아직 초안이고 준비 체크는 0/4입니다. 바탕은 dev라서 바꿀 필요가 없습니다. types.ts/config.ts 분할 때문에 닫을 이유도 없습니다.

너의 추천

기억 호출만 OpenAI로 새는 것을 단계별로 막는 방향은 맞습니다. 경고 문장과 나오는 조건을 맞추고, 웹소켓에서는 연결 헤더의 서브에이전트 표시로 단계를 정하지 않게 한 뒤 머지하면 됩니다. 파일을 직접 고친 설정은 깨진 단계만 빠지게 하는 편이 127줄 주석과 같습니다. 압축 라우팅 패널에는 gui/tests/compaction-routing-panel.test.tsx가 있고, 이 패널 테스트는 없습니다. 경고 조건은 그 테스트가 있으면 잡힙니다.

Thanks for the review — all three findings are addressed in 70ab7a4:

1. Account notice (MemoryModelsPanel.tsx:176, i18n). The notice now names its own condition: it appears only while exactly one phase is routed, and the sentence says so in every locale ("Only one phase is routed; the other still sends its memory calls to your OpenAI account like any other native model."). The both-off default stays quiet — that state is Codex's own choice, which the panel description already states, so a yellow notice there would repeat it on every load. The condition is pinned by the new gui/tests/memory-models-panel.test.tsx ("the account notice tracks the half-routed state"), which walks both phases through routed/unrouted and asserts the notice appears and disappears exactly at the half-routed state.

2. WebSocket sub-agent header (memory-models.ts:85). WebSocket frames no longer consult x-openai-subagent at all. The bridge re-attaches the handshake's header to every frame, so on that transport the header marks the connection, not the pass; the per-frame turn metadata is the only websocket signal, and a consolidation connection's later ordinary turns are no longer swept into the consolidation phase. HTTP keeps the header fallback, since Codex may deliver only that copy. New test: "the connection's sub-agent header consolidates HTTP turns but not websocket frames". server.md documents the split.

3. Per-phase config degrade (config-schema.ts:162). The load-time schema now catches per phase: a hand-edited broken consolidation entry drops only itself and a valid extract survives. A wholly broken block still drops entirely with the block-level wording, and a broken phase warns per phase ("memoryModels.extract is invalid — that phase keeps Codex's own model"). The management write boundary still rejects the value outright through the shared catch-free schema, unchanged.

On the decision points: the notice stays on the half-routed state, websocket detection is per-frame only, and the degrade is per phase — each matching the recommendation. Full suite on this head is green except tests/codex-integration/native-codex-toggle.test.ts, which fails identically at the base commit and is documented in the Verification section.

Thanks — all six are addressed in the current head.

src/server/management/config-routes.ts — the PUT response now echoes memoryModels. This one was real: the panel re-reads the response of its own save, so a response without the block rendered both rows as "Off" while the server kept the setting. The success response carries the saved block next to compactionRouting, and the new tests/config/settings-memory-models.test.ts pins the echo, the round trip through loadConfig(), the null clear, and the rejection before any mutation.

accountNotice (en, ja, zh and the other seven locales) no longer claims the unrouted phase reaches the OpenAI account. You are right that an unrouted Extract shares its model ID with the title and commit helper traffic, so shadowCallIntercept can route it to its configured target. The notice now says the phase keeps its existing route and names Shadow Call Intercept as the other actor.

dataNotice (ko, tr and the other eight locales) now names each phase's input. Consolidation reads raw memories, not a finished session, so "the session text" was wrong for that phase. The shared notice now reads "that phase's input: the finished session for Extract, the raw memories for Consolidation".

Also in this head: the ⓘ next to the panel title is centred on the heading like the sibling panels' buttons (same display: flex; align-items: center title row), and the PR screenshot was regenerated for the new notice text.

Holding approval on current head 34f131f3: this broad config/routing/GUI change conflicts with current dev and has no executable exact-head CI. Static review did not confirm a new defect, and the prior PUT-response omission appears fixed, but the conflict-resolved head still needs Responses/settings/GUI evidence for metadata disagreement, per-frame WebSocket classification, combo failover, admission denial, and unavailable targets.

[robin-bially]

Rebased onto dev at 5518653a9 — 0 commits behind, and the PR is no longer CONFLICTING.

The conflict was a union of two independent config additions: dev's compactionRecovery and this branch's memoryModels. Four files carried both, and each now keeps both sides:

• src/config/schema/config-schema.ts — compactionRecovery: compactionRecoverySchema.optional().catch(undefined) next to the per-phase memoryModels object, which keeps its per-phase catch so one malformed phase disables only that phase.
• src/config/diagnostics.ts — compactionRecoveryConfigError(value) ?? configReasoningPinsConfigError(value) before the strict memoryModelsSchema check.
• src/server/management/config-routes.ts — the settings GET/PUT validate, apply, echo and roll back both (["compactionRouting", "compactionRecovery", "memoryModels"]).
• tests/helpers/responses-core-source.ts — the module list names compaction-recovery.ts, compaction-recovery-policy.ts and memory-models.ts.

The diff against dev is purely additive.

Evidence for the five scenarios, all at the rebased head f9618cec0:

• metadata disagreement — tests/responses/responses-memory-models.test.ts: "conflicting copies are not treated as a memory turn", "both copies must agree on the same phase", "an ordinary turn, absent metadata, or malformed metadata is never a memory turn".
• per-frame WebSocket classification — same file: "WebSocket frames read the body copy instead of the handshake header", "the connection's sub-agent header consolidates HTTP turns but not websocket frames".
• combo failover — same file: "the phase decision survives the combo handoff".
• admission denial — same file, new case: "an admission denial on the memory target keeps the key's own refusal". A scoped key whose provider list excludes the memory target gets 403 model_not_allowed_for_key and nothing is sent. resolveChosenTarget rethrows AdmissionModelDeniedError rather than reporting the target as unavailable, and nothing covered that before, so the case is new here.
• unavailable targets — same file: "a target that no longer resolves fails the memory call instead of falling back" (409, memory_model_target_unavailable, no send), plus the existing lifecycle cases in tests/responses/shadow-intercept-target-lifecycle.test.ts.
• settings and GUI — tests/config/settings-memory-models.test.ts (4 pass: PUT echoes the saved block, null clears it, a malformed phase is rejected before any mutation) and gui/tests/memory-models-panel.test.tsx (2 pass).

Executable exact-head CI: this is a fork PR, so the repository test workflow does not run on it — only enforce-target, hygiene, label and resolve-pr do. The executable evidence is the suite above, run in a clean checkout outside the agent home: bun run test at f9618cec0 ran a parallel lane of 32211 tests across 1781 files in 306 s (32165 pass / 43 skip / 3 fail), and the serial lanes added one more. All four are environment-only: the three shutdown-launcher SIGINT/SIGTERM/SIGHUP timeouts fail identically in isolation at the dev tip with this branch absent (a live proxy owns client routing on port 10100), and the native-codex-toggle off-then-on case passes 13/13 in isolation at both heads. As a control, the same suite at 5518653a9 without this change set produced twelve failures — those four plus eight more load-sensitive ones — so the machine is noisy, not the branch. cd gui && bun test tests is 2553 pass / 0 fail, and bun run typecheck, bun run lint:gui, bun run build:gui and bun run privacy:scan are clean.

Two findings came out of re-running everything at the new head, both fixed in f9618cec0:

1. The union with dev tripped the file-size ratchet: dev's scripts/test-layout/layout.json was already at 1998 lines, and this branch's two explicit rows took it to exactly 2000, which the ratchet counts as oversized. Both names are placed by the domain seeds (responses-, settings-) — the path the layout tooling test documents for a conventionally named file — so the rows are dropped and the map and its fixture stay identical. Worth knowing beyond this PR: the next branch that registers two test files trips the same ratchet, unless layout.json is treated as a data snapshot in DATA_SNAPSHOT_PATHS. I did not fold that into this PR.
2. gui/tests/fr-localization.test.ts rejects a French value identical to its English source, and memoryModels.consolidation was that shape. "Consolidation" is the ordinary French noun, so the key joins that test's allowlist; renaming it would also break the pair with the extract row, whose French label is "Extraction".

The description carries the same evidence and the review-readiness boxes are ticked against f9618cec0.

Rebased onto the current dev tip e2ae5f2dc.

dev had moved 25 commits ahead, past the readiness check's 10-commit tolerance. The twelve commits replayed patch-identically and without a conflict, so the only difference to the previous head is the base itself, and the diff against dev stays purely additive (31 files, +1455/−12).

Verified at the new head dca863465:

• bun run typecheck, bun run lint:gui, bun run privacy:scan — clean; bun run build:gui — built.
• react-doctor --scope changed --base e2ae5f2dc --blocking warning — "No issues found" (100/100) over the 14 changed files.
• Focused set — 60 pass, 0 fail: tests/responses/responses-memory-models.test.ts, tests/config/settings-memory-models.test.ts, tests/test-layout.test.ts, tests/test-layout-tooling.test.ts, tests/ci-workflows/file-size-ratchet.test.ts (including the repository scan), tests/responses/responses-core-modules.test.ts.
• cd gui && bun test tests — 2590 pass, 0 fail across 300 files.
• bun run test — parallel lane 32719 tests across 1805 files in 410.4 s. Ten failures in three files, all environment-only and all green in isolation at this head: the three tests/service/shutdown-launcher.test.ts cases (a live proxy holds client routing on port 10100; 0 pass / 3 fail in isolation, and they fail identically at the dev tip 429f4e017 with this branch absent), plus tests/claude-integration/claude-models-discovery.test.ts (13/13) and tests/codex-integration/native-codex-toggle.test.ts (13/13), both load-sensitive and only red while the GUI suite ran concurrently. Nothing is attributable to this change.

The review-readiness boxes are re-ticked against dca863465. The Cross-platform CI and React Doctor runs for this head need a maintainer to approve them again, as for every previous head — a fork PR cannot start its own CI.

Added a commit so an enabled shadowCallIntercept covers the whole memory pipeline, not just phase 1.

Codex asks gpt-5.6-terra for the background memory-consolidation pass. That is helper traffic by role, but it was not in the default shadow source models, so on a routed install the consolidation stayed on the native account while extract was already intercepted through the gpt-6-luna/gpt-5.6-luna helper slug. gpt-5.6-terra now joins the default source models, which keeps that phase off the account the operator routed away from.

The test that asserted isShadowSourceModel("gpt-5.6-terra") is false came from the source-model-set change (issue #311), where terra was one example alongside gpt-5.5 and gpt-5.6-sol rather than a statement about its role. It now asserts the rewrite instead, including for a turn tagged x-openai-subagent: memory_consolidation.

The GUI fallback, the config type docs, the structure map and the configuration docs in every locale follow the list.

Verified at cd45810fa:

• bun run typecheck, bun run structure:check, bun run lint:gui, bun run privacy:scan — clean; bun run build:gui — built.
• react-doctor --scope changed --base e2ae5f2dc --blocking warning — "No issues found" (100/100) over the 16 changed files.

Thank you @robin-bially for Codex memory-phase model routing. It landed on dev through #6124 (merge commit 296f0ce), with your authorship recorded in Co-authored-by trailers. The carry kept per-phase model and effort selection on HTTP and WebSocket, made explicit turn metadata (including malformed or null client_metadata) authoritative over the x-openai-subagent fallback, and left the default Terra shadow-call change out so users without memory routing see no change. Closing this PR as carried; the full review trail is on the lane PR linked from #6124.
