+# gpt-5.4 / gpt-5.4-mini retirement on the Codex login surface
+
+## Objective
+
+OpenAI retired `gpt-5.4` and `gpt-5.4-mini`. Remove them from the Codex (ChatGPT
+OAuth) login surface of this proxy: the native catalog, everything that projects it
+(`/v1/models`, the dashboard picker, the desktop projection, Claude discovery), and
+every opencodex-owned default that still dispatches one of the two slugs.
+
+The replacement floor is `gpt-5.6-luna` — it is now the cheapest native model on the
+ChatGPT login lane, so every helper/sidecar/warmup default lands there. The login
+provider's own `defaultModel` moves there too: `gpt-5.6-sol` was considered because it
+is priority 1 in the pinned snapshot and `gpt-5.4` held a general-purpose role, but the
+owner chose luna so a default that nobody asked for stays the cheapest live model
+(owner decision, 2026-09-12).
+
+## Constraints and scope boundary
+
+In scope: `src/codex/**`, `src/oauth/**`, `src/vision/**`, the Codex-login parts of
+`src/server/**`, `src/cli/**`, `src/types/**`, `src/lib/shadow-call.ts`, `gui/`,
+`docs/` (the maintainer-facing pages, not only `docs-site/`), `docs-site/` (all locales),
+`structure/`, `scripts/release-notes.ts`, and `tests/`.
+
+Out of scope, deliberately:
+
+- Third-party vendor rosters that publish their own snapshots — `github-copilot`
+  (`src/providers/registry.ts`), `cursor` (`src/adapters/cursor/*`), `codebuddy`,
+  `opencode`, `command-code`, and `scripts/model-metadata.source.json`. This follows
+  the `deepseek-v4-pro` precedent (`e86ab5bd8d`): a first-party retirement notice does
+  not end a vendor's deployment, and deleting their row would strip a live route's
+  context window and effort ladder while the model keeps arriving from `/models`.
+- Historical pricing in `src/usage/expected-prices.ts` and its tests. Past usage rows
+  still have to cost correctly after the model stops being routable.
+- Slugs that only look related: `gpt-5.4-nano`, `gpt-5.4-pro`, `gpt-5.4-high`,
+  `openai/gpt-5.4-mini` (OpenRouter metadata). None are part of this retirement.
+
+No push, PR, merge, release, or deploy. Local commits only.
+
+## Evidence gathered at P
+
+Three read-only `xai/grok-4.6` verifier subagents swept the tree in parallel. Their
+combined inventory: 146 files, 592 `gpt-5.4*` hits, of which the Codex-login-owned
+set is the one this unit changes.
+
+Structural findings that shape the phase order:
+
+1. `NATIVE_OPENAI_MODELS` (`src/codex/catalog/native-models.ts:156`) is the single
+   membership list. `SUPPORTED_NATIVE_OPENAI_SLUGS`, `nativeModelRows`,
+   `nativeOpenAiSlugs`, `accountBoundNativeOpenAiSlugsBySelector`,
+   `filterSupportedNativeSlugs`, `model-routes.ts` `supportedNative`, and
+   `CANONICAL_NATIVE_CATALOG_CONTENT_POLICY.nativeBackfillSlugs` all derive from it.
+   Removing the two slugs there propagates to every projection without further edits.
+2. Persisted BARE rows clean themselves up. Once the slugs leave the list,
+   `isUnsupportedOpenAiNativeSlug` returns true for `gpt-5.4` and `gpt-5.4-mini` and the
+   canonical merge runs `unsupportedNativeEntries: "drop"` (`sync.ts:847`, filter at
+   `1068-1070`), so a user's on-disk catalog loses them on the next sync.
+   Account-namespaced rows are a different path: that predicate returns false for any slug
+   containing `/` (`metadata.ts:113`), so `team/gpt-5.4` is not dropped by it. Those rows
+   stop being *generated* because `accountBoundNativeOpenAiSlugsBySelector` and
+   `availableAccountNativeSlugs` both seed from `NATIVE_OPENAI_MODELS`. wp2 must prove what
+   happens to an already-persisted `selector/gpt-5.4` row with a focused test rather than
+   assuming it disappears.
+3. `UPSTREAM_NATIVE_ENTRIES` never contained either slug — `upstreamNativeEntryForSlug`
+   admits only `gpt-5.6-*` and self-described natives — so deleting the two pinned rows
+   in `src/codex/data/upstream-models.json` changes capability fallbacks only, not the
+   sync-replacement authority. `gpt-5.2` and `codex-auto-review` stay pinned, which is
+   why `SELF_DESCRIBED_NATIVE_OPENAI_MODELS` must remain an explicit allowlist.
+4. The defaults are independent of the catalog list and fail separately. Warmup
+   (`src/codex/warmup.ts:30`), the token guardian (`src/oauth/token-guardian.ts:55`),
+   and the vision describer (`src/vision/plan.ts:14`) all still dispatch
+   `gpt-5.4-mini` and would 404 after retirement regardless of catalog membership.
+5. The startup sidecar migration (`src/server/index.ts:686`) rewrites a *stored*
+   `gpt-5.4-mini` to `gpt-5.6-luna`, but an unset vision model never equals that
+   string, so it falls through to `DEFAULT_VISION_MODEL` and still calls the retired
+   model. That gap is the reason wp3 exists as its own cycle.
+6. `DEFAULT_SHADOW_SOURCE_MODELS` is already `["gpt-5.6-luna"]`. `gpt-5.4-mini` there
+   is an *inbound* prefix for Codex 0.144.x helper calls, not a dispatch target, so it
+   stays documented as a restore option and is not treated as a retired default.
+
+## Work-phase map
+
+| Phase | Unit doc | Outcome | Depends on |
+|---|---|---|---|
+| wp1 | this document | Roadmap locked, scope boundary recorded | — |
+| wp2 | `010_catalog_removal.md` | The two slugs leave the native catalog and its pinned metadata | wp1 |
+| wp3 | `020_defaults_repoint.md` | Every opencodex-owned default moves to a live slug | wp1 |
+| wp4 | `030_surfaces_and_gate.md` | GUI, docs locales, structure docs, full gate, closing record | wp2, wp3 |
+
+wp2 and wp3 touch disjoint files and could run in either order; wp2 runs first because
+its membership decision is what the wp3 tests assert against.
+
+## Risks
+
+- **Over-removal.** Deleting a vendor roster row would break a live Copilot or Cursor
+  route. Mitigation: the scope boundary above, plus a final `rg` sweep that expects
+  vendor hits to remain.
+- **Under-removal.** A default left on `gpt-5.4-mini` turns into a silent 404 on every
+  warmup or image description. Mitigation: wp3 enumerates each default site explicitly.
+- **Test churn masking a real break.** ~278 test hits are in scope. Mitigation: each
+  test edit is classified as membership (must change), floor (must repoint), or
+  historical (must not change), and the full suite is the closing gate.
+
+## Acceptance
+
+DONE requires: no retired slug in a Codex-login-owned surface, every default on a live
+slug, `bun run typecheck` clean, the focused domain suites green, the full
+`bun run test` green, `bun run structure:check` green, and this unit carrying a closing
+record with quoted evidence.

+# wp2 — Remove the retired slugs from the Codex-login native catalog
+
+Membership only. No default moves here; that is wp3.
+
+## MODIFY src/codex/catalog/native-models.ts
+
+`NATIVE_OPENAI_MODELS` line 156. Before:
+
+```ts
+  "gpt-5.5", "gpt-5.4", "gpt-5.4-mini", "gpt-5.3-codex-spark",
+```
+
+After:
+
+```ts
+  "gpt-5.5", "gpt-5.3-codex-spark",
+```
+
+Two comments name the removed slugs as examples and must stop doing so, because after
+this change they would describe a list that no longer holds them:
+
+- line 75, in the `SELF_DESCRIBED_NATIVE_OPENAI_MODELS` doc comment: the sentence "the
+  pin also holds `gpt-5.5`, `gpt-5.4` and `gpt-5.4-mini`" stays true of the snapshot, but
+  the retired slugs are no longer admission candidates at all. Rewrite it around the pins
+  that remain reachable — `gpt-5.5`, `gpt-5.2`, `codex-auto-review` — so the reason the
+  allowlist is explicit rather than structural survives the retirement.
+- line 175, in `NATIVE_MAIN_DRAIN_SENTINEL_MODELS`: drop `gpt-5.4` and
+  `gpt-5.4-mini` from the "would have widened the sentinel to" enumeration, leaving
+  `gpt-5.5` and `gpt-5.3-codex-spark`. The set itself is unchanged — neither slug
+  was ever a member.
+
+## MODIFY src/codex/catalog/metadata.ts
+
+Line 165, `NATIVE_OPENAI_CONTEXT_OVERRIDES`: DELETE
+`"gpt-5.4": { contextWindow: 1_000_000, maxContextWindow: 1_000_000 },`. This was the
+only 1M native; `gpt-5.4-mini` has no entry and took its window from the pin.
+
+Line 123, the operating-cap comment: the sentence "and gpt-5.4 runs 272,000 against
+1,000,000" describes a row that is going away. Rewrite it to cite only the GPT-5.6
+slugs it already discusses.
+
+Line 540, the `upstreamNativeEntryForSlug` allowlist comment: "would also admit
+gpt-5.5/gpt-5.4/gpt-5.4-mini" becomes "would also admit gpt-5.5/gpt-5.2/codex-auto-review".
+The behaviour is unchanged; the example set follows the pins that can still be reached.
+
+## KEEP src/codex/data/upstream-models.json (audit reversal)
+
+The plan originally called for deleting the two pinned objects (`"slug": "gpt-5.4"` at
+line 460, `"slug": "gpt-5.4-mini"` at line 565). The A phase reversed that.
+
+This file is a snapshot of upstream's bundled catalog, and `metadata.ts:580` states the
+contract: "The pinned JSON is left byte-identical to upstream; only the projection fills
+in." The snapshot already carries `gpt-5.2` and `codex-auto-review`, neither of which is
+in `NATIVE_OPENAI_MODELS`, so a pinned row has never been an exposure decision.
+
+Nothing re-exposes a retired slug from the snapshot alone. `PINNED_NATIVE_CAPABILITY_ENTRIES`
+and `UPSTREAM_NATIVE_ENTRIES` are both built by iterating `NATIVE_OPENAI_MODELS`, so once
+the slugs leave that list their pinned rows are never looked up. The one consumer that
+reads raw snapshot rows, `GATED_MODEL_CLIENT_VERSION_FLOOR` in
+`src/codex/model-entitlements.ts:135`, filters on `ACCOUNT_GATED_NATIVE_OPENAI_MODELS`
+(Daybreak only) and never sees them.
+
+Deleting ~205 lines of upstream-owned JSON would change no behaviour while breaking the
+file's fidelity to its source and churning `reserve-catalog-lifecycle.test.ts` and
+`codex-model-entitlements.test.ts`, which read it directly. Membership is the lever.
+
+## MODIFY src/codex/catalog/parsing.ts, src/codex/catalog/effort.ts, src/codex/catalog/sync.ts
+
+Comment-only. Each names `gpt-5.4` or `gpt-5.4-mini` as the illustrative "older native"
+(`parsing.ts:521` preserved-row cap, `effort.ts:62` xhigh clamp, `sync.ts:263` mock
+max/ultra). Replace the examples with `gpt-5.5` / `gpt-5.3-codex-spark`. No predicate
+changes: the clamp keys on "is not a gpt-5.6 native", so a request that still names a
+retired slug is still clamped correctly.
+
+## Tests
+
+Membership assertions that must drop the slugs:
+
+- `tests/codex-integration/codex-catalog.test.ts` — `filterSupportedNativeSlugs`
+  expectation at 6954 and the visibility inputs at 6943-6944; delete the "native gpt-5.4
+  uses its 1M context window override" test at 3459-3466 with the override itself.
+  The "preserved gpt-5.4-mini rows get the openai cap" test at 3640-3678 cannot simply be
+  kept: it feeds a preserved row through `mergeCatalogEntriesForSync`, and after membership
+  removal that row is a droppable unsupported native. Run it first — if it drops, repoint
+  the fixture onto a surviving non-overridden native so the #1430 cap regression keeps its
+  coverage. Line 3686 (`nativeOpenAiContextWindow("gpt-5.4", 272_000)`) names a retired
+  slug in a test about the generic cap, so repoint it too.
+  KEEP 3817 (negative: the slugs must not leak into `UPSTREAM_NATIVE_ENTRIES` — still true
+  and now trivially so), KEEP the Nova1 routed alias fixtures at 1175-1205 and the cursor
+  rows at 4340-4893.
+- `codex-catalog-sync-hardening.test.ts` 118-140, 275-281, 373-376 — repoint the native
+  fixtures onto `gpt-5.5` / `gpt-5.6-luna`; 729-765 likewise.
+- `codex-catalog-golden.test.ts` 41 and the `"gpt-5.4@9"` golden projection at 76.
+- `codex-catalog-model-picker-order.test.ts` 153-167.
+- `codex-catalog-restore.test.ts` — the hide/priority/window fixtures listed in the
+  audit; the 1M expectation at 398 goes with the override.
+- `native-model-toggle.test.ts` 71-72 and 299. KEEP 79 (`cursor/gpt-5.4` proves vendor
+  slugs are ignored by native visibility) and 234-243 (preserved compact-limit map).
+- `model-visibility-management-api.test.ts` 376-436 — a removed slug is no longer a
+  valid native visibility target, so these move to a surviving native.
+- `codex-convergence-account-selectors.test.ts`, `codex-auth-context.test.ts`,
+  `codex-metadata-integrity.test.ts`, `codex-v2-gate.test.ts`, `effort-policy.test.ts`
+  281-315 — these use the slug as a live native request id; repoint to `gpt-5.5`.
+  `effort-policy.test.ts` 435-439 keeps testing the clamp, on a surviving old native.
+- `tests/claude-integration/` — `claude-models-discovery.test.ts` expected roster,
+  `claude-model-info.test.ts` (its "only authoritative 1M native" claim dies with the
+  override), `claude-context-windows.test.ts` 24-29, `claude-inbound.test.ts`.
+- `tests/clients/desktop-3p.test.ts` 215-221 — same 1M native subject.
+
+Do not touch: `tests/usage/**`, `tests/providers/**` vendor suites,
+`tests/fixtures/commandcode-models.json`, `tests/responses/responses-shadow-intercept.test.ts`,
+`tests/routing/subagent-*` (operator rosters and a negative sentinel assertion).
+
+Four more in-scope files the first sweep left unclassified:
+`tests/codex-integration/codex-app-server-processes.test.ts:491-500` KEEP (the
+`codex --config model=...` fixture exercises a command-line detector; any token works),
+`tests/codex-integration/slug-codec.test.ts:106` KEEP (codec round-trip pair, not
+membership), `tests/responses/empty-completion-guard.test.ts:467` KEEP (string formatting),
+`tests/vision/vision-eligibility.test.ts:225` REPOINT to `gpt-5.6-luna` — unlike the
+OpenRouter rows at 22-26 this one is the native eligibility subject and belongs to wp3.
+

+`bun test tests/codex-integration tests/claude-integration tests/clients` green, plus

+# wp3 — Move every opencodex-owned default off the retired slugs
+
+Every lane goes to `gpt-5.6-luna`, including the login provider default (owner
+decision, 2026-09-12). Each site below dispatches a real request today and would 404
+after retirement.
+
+## MODIFY src/oauth/index.ts
+
+Line 331, the `chatgpt` OAuth definition: `defaultModel: "gpt-5.4"` becomes
+`defaultModel: "gpt-5.6-luna"`.
+
+Be accurate about what this constant does, because the first draft of this plan was not:
+`upsertOAuthProvider` returns at `src/oauth/index.ts:1476` for `chatgpt`, so the value is
+never persisted onto a provider row, and `src/cli/models.ts:139`, `src/cli/provider.ts`
+and `src/server/fast-row.ts:133` all read `config.providers[*].defaultModel` rather than
+this constant. It is the ChatGPT login definition's declared default, not a live 404
+dispatch path. It still moves: leaving a retired slug as the login surface's stated
+default is wrong on its own terms, and any future consumer would inherit it.
+
+## MODIFY src/oauth/token-guardian.ts
+
+Line 55, `DEFAULTS.codexWarmupModel`: `"gpt-5.4-mini"` becomes `"gpt-5.6-luna"`.
+Line 87 reads a stored override first, so a user who explicitly set
+`tokenGuardian.codexWarmupModel: "gpt-5.4-mini"` keeps calling the retired model.
+Extend the existing startup migration (below) to rewrite that stored value too.
+
+## MODIFY src/codex/warmup.ts
+
+Line 30: `const DEFAULT_MODEL = "gpt-5.4-mini"` becomes `"gpt-5.6-luna"`.
+Line 31: `FALLBACK_MODELS = ["gpt-5.5", "gpt-5.6-luna"]` becomes `["gpt-5.5"]` — luna
+is now the primary, and the loop already skips a fallback equal to the primary, so
+leaving it would be dead weight that reads as a second chance.
+
+## MODIFY src/vision/plan.ts
+
+Line 14: `const DEFAULT_VISION_MODEL = "gpt-5.4-mini"` becomes `"gpt-5.6-luna"`.
+Lines 71 and 87 consume it and need no edit. This is the one that the startup sidecar
+migration cannot reach: an unset `visionSidecar.model` never equals the old string, so
+today an untouched install still describes images with a retired model.
+
+After this, `src/vision/eligibility.ts:51` and `src/vision/backends.ts:51` — both
+already `gpt-5.6-luna` — agree with the runtime instead of contradicting it.
+
+## MODIFY src/server/management/config-routes.ts
+
+Lines 823-824, the vision effort-table normalization: both `"gpt-5.4-mini"` literals
+become `"gpt-5.6-luna"`. Lines 724 and 963 are already luna and stay.
+
+## MODIFY src/cli/config-command.ts
+
+Line 148: `const model = vision.model || "gpt-5.4-mini"` becomes `"gpt-5.6-luna"`, and
+the line 147 comment that names the old bounded default follows it.
+
+## MODIFY src/server/index.ts
+
+KEEP the sidecar migration block at 686-701 — it is the only thing that rewrites a
+stored `gpt-5.4-mini` for existing users, and its destination is already luna. Two
+changes:
+
+1. Extend it to `config.tokenGuardian?.codexWarmupModel === "gpt-5.4-mini"`, which is
+   currently not migrated and is a live dispatch path.
+2. Correct the comment: it claims "explicit user choices are preserved", but the check
+   is exact equality, so an explicitly chosen `gpt-5.4-mini` is rewritten too. After
+   retirement that is the right behaviour; the comment should say so rather than
+   describe a guarantee the code does not make.
+
+The `SIDECAR_MIGRATION_CUTOFF` date gate stays as-is.
+
+## MODIFY src/types/config.ts, src/types/tools.ts, src/types/request.ts
+
+Doc comments only, but they are the published contract:
+
+- `config.ts:1125` — "Default gpt-5.4-mini" for `codexWarmupModel` becomes luna.
+- `config.ts:604` and `:614` — the shadow-intercept comments claim both slugs are
+  defaults while the code ships luna only. Correct them to state the default is
+  `gpt-5.6-luna` and `gpt-5.4-mini` is an opt-in `sourceModels` value for 0.144.x
+  clients.
+- `tools.ts:16` and `request.ts:103` — the synthetic web_search comments still name a
+  "gpt-5.4-mini sidecar"; `src/web-search/index.ts:23` has been luna for a while.
+
+## KEEP src/lib/shadow-call.ts
+
+`DEFAULT_SHADOW_SOURCE_MODELS` stays `["gpt-5.6-luna"]` and the 0.144.x note stays.
+This list is what the proxy *intercepts*, not what it sends: a 0.144.x client emitting
+`gpt-5.4-mini` helper calls is exactly who benefits from an intercept, and an operator
+can restore the prefix through `sourceModels`. Adding it back to the default would
+change intercept behaviour for every install, which is a separate decision from
+retiring the model.
+
+## Tests
+
+- `tests/codex-integration/warmup.test.ts` 97-141, `codex-warmup.test.ts` 38/55,
+  `token-guardian.test.ts` 253, `codex-quota-auto-refresh-main-admission.test.ts` 290 —
+  the warmup chain becomes `gpt-5.6-luna` then `gpt-5.5`.
+- `tests/vision/**` — `sidecar-abort.test.ts` (21 fixtures), `vision-reasoning-contract.test.ts`
+  (14, retune to luna's ladder), `sidecar-settings-vision-filter.test.ts` 137/189,
+  `sidecar-settings-vision-controls.test.ts` 89, `vision-anthropic.test.ts` 419.
+  KEEP `vision-eligibility.test.ts` 22-26 (OpenRouter `openai/gpt-5.4-mini` metadata).
+- `tests/web-search/web-search.test.ts` — 26 settings fixtures move to luna.
+- `tests/server/server-combo-failover-e2e.test.ts` — 10 live-forward model ids.
+- A new regression for the widened migration: a stored
+  `tokenGuardian.codexWarmupModel: "gpt-5.4-mini"` is rewritten to luna at startup.
+- `tests/vision/vision-eligibility.test.ts:225` — the native eligibility subject moves to
+  luna; 22-26 stay (OpenRouter `openai/gpt-5.4-mini` metadata).
+- KEEP `tests/server/config.test.ts` 98 and `server-startup-reconcile-resilience.test.ts` 57
+  (legacy roster inputs), `tests/server/api-debug.test.ts` (log-parser fixture),
+  `tests/responses/**` (shadow restore hatch), `tests/usage/**` (historical pricing).
+
+## Proof for this phase
+
+`bun test tests/vision tests/web-search tests/server tests/codex-integration` green,
+plus `bun run typecheck`.

+  in `gpt-5.4-mini`, while `DEFAULT_SUBAGENT_MODELS` is already Astra/sol/terra/luna/5.5.
+  Make the docs match the shipped default.
+- `guides/codex-integration.md` — the account-verification warmup sentence becomes
+  "defaults to `gpt-5.6-luna`, retries with `gpt-5.5`".
+- `reference/configuration/providers.md` — `codexWarmupModel` default cell → luna.

+- `guides/sidecars.md` — the code fallback → luna; keep the migration sentence.
+- `reference/configuration/agents.md` and `guides/sub-agent-surface.md` — the

+  while English says luna only.
+- `guides/codex-integration.md` explicit-account example `work/gpt-5.4` → `work/gpt-5.5`,

+
+## MODIFY docs/ (maintainer-facing, separate from docs-site)
+
+- `docs/shadow-call-intercept.md:14-17` — says the default source-prefix set is
+  `gpt-5.4-mini` and `gpt-5.6-luna`. `DEFAULT_SHADOW_SOURCE_MODELS` is luna-only, so this
+  page is already wrong today. State luna as the default and `gpt-5.4-mini` as the 0.144.x
+  restore value, matching the correction in `src/types/config.ts` from wp3.
+- `docs/codex-app-model-catalog.md:111` — uses `gpt-5.5`/`gpt-5.4` as the example of
+  snapshot entries that are staler than the installed catalog. Replace the retired half of
+  the example.
+
+## MODIFY structure/
+
+- `structure/ops/service-and-sidecars.md:52` — vision default cell → `gpt-5.6-luna`.
+- `structure/gui-and-management-api.md:129` — the shadow `sourceModels` sentence says
+  the default is `gpt-5.4-mini` + `gpt-5.6-luna`; the code ships luna only. Correct the
+  default and keep mini as the documented restore value.
+
+## MODIFY scripts/release-notes.ts
+
+Line 1137 — `process.env.OPENAI_MODEL ?? "gpt-5.4"` becomes `?? "gpt-5.6-luna"`. The
+tool is maintainer-facing but would fail against a retired model.
+KEEP `scripts/model-metadata.source.json` entirely: 129 hits across vendor snapshots
+plus openai/openai-codex pricing rows, none of which are the Codex-login catalog.
+
+## Closing gate
+
+1. `bun run typecheck`
+2. `bun run test` (full suite, PR-ready gate)
+3. `bun run lint:gui` and the GUI tests
+4. `bun run structure:check`
+5. Final `rg "gpt-5\\.4"` sweep, read against an explicit allowlist rather than an
+   expectation of zero hits. Survivors that are CORRECT and must remain:
+   vendor rosters (`src/providers/registry.ts` Copilot, `src/adapters/cursor/*`,
+   `src/providers/codebuddy-models.ts`, `scripts/model-metadata.source.json`,
+   `tests/providers/**`, `tests/fixtures/commandcode-models.json`, the Copilot/mixed-wire
+   docs pages); historical pricing (`src/usage/expected-prices.ts`, `tests/usage/**`,
+   `docs-site/src/data/frontier-benchmarks.json` benchmark rows);
+   generated metadata (`src/generated/model-metadata.ts`); different slugs
+   (`-nano`, `-pro`, `-high`, `openai/gpt-5.4-mini`, `cursor/gpt-5.4`); the shadow-intercept
+   restore hatch (`src/lib/shadow-call.ts`, `tests/responses/**`, the sourceModels docs);
+   negative and fixture assertions (`tests/routing/subagent-*`, `tests/server/api-debug.test.ts`,

+   `codex-app-server-processes.test.ts`, `slug-codec.test.ts`, `empty-completion-guard.test.ts`,
+   `codex-catalog.test.ts:3817`); and this devlog unit. A hit outside that list is a defect.

+# Closing record
+
+## Outcome
+
+DONE. `gpt-5.4` and `gpt-5.4-mini` no longer exist on the Codex (ChatGPT OAuth) login
+surface, and every default that used to dispatch one of them now uses `gpt-5.6-luna`.
+Delivered as PR #4327 against `dev`, final head `32bd5417cb`, CI green.
+
+Commits: `a8b26e1342` (this roadmap), `5d664b1a6b` (the retirement),
+`fa1fe32890` (a combo-alias fixture CI caught), `fe01c0f605` (the resurrection guard a
+review caught), `32bd5417cb` (the migration extracted and tested).
+
+## What changed against the plan
+
+Two reversals, both from audit rather than from build convenience.
+
+The pinned rows in `src/codex/data/upstream-models.json` stayed. The plan called for
+deleting them; the A phase found the file is upstream's snapshot by contract
+(`metadata.ts:580`) and already carries rows this runtime does not expose (`gpt-5.2`,
+`codex-auto-review`). Both maps built from it iterate `NATIVE_OPENAI_MODELS`, so the
+rows are unreachable once membership is gone. Deleting ~205 lines would have changed
+no behaviour.
+
+The maintainer-facing `docs/` tree was missing from the original scope entirely. The
+independent reviewer caught it: `docs/shadow-call-intercept.md` still claimed the
+default intercept set was both slugs when the code had been luna-only for a while, and
+`docs/codex-app-model-catalog.md` used `gpt-5.4` as a staleness example.
+
+## What CI caught that reading did not
+
+Two defects survived the audit and the six parallel test workers, and were found only
+by pushing:
+
+1. `tests/codex-integration/codex-catalog.test.ts` had a native-alias combo fixture
+   targeting `codex/gpt-5.4-mini`. Once membership was gone that alias had no native
+   capabilities to inherit. `gpt-5.5` carries an identical pinned shape (272k window,
+   `low..xhigh`, default `medium`, text and image), so every asserted value held after
+   repointing.
+2. `enforce-target` fails on any `gui/` path change without screenshot evidence. There
+   is no visual change here, so it was waived through the repository's documented
+   maintainer-comment mechanism with a note stating exactly what the `gui/src` diff is.
+
+## What the final review caught that CI did not
+
+CI was green and the change was still wrong in one place. An independent reviewer read
+the pushed diff and found that removing the slugs from `NATIVE_OPENAI_MODELS` does not
+keep them out: an account-bound observation deliberately admits any native that is NOT
+in `SUPPORTED_NATIVE_OPENAI_SLUGS`, which is how a genuinely new upstream model reaches
+one entitled account early. A retired slug fails that same test, so a stale
+`selector/gpt-5.4` row persisted in a user's catalog or models cache would have been
+re-observed as an unknown native and synthesized straight back into the picker, one sync
+after the removal took it out.
+
+`RETIRED_NATIVE_OPENAI_MODELS` is the distinction the code was missing: unknown-and-new
+is admitted, known-and-dead is refused. The guard sits in `observedAccountBoundNativeSlug`
+because every observation path funnels through it.
+
+This is the residual wp2 recorded as needing proof rather than assumption, and it is the
+reason that residual was worth writing down: no test covered it, so no test failed.
+
+The same review noted the widened startup migration had no test at all. It is now
+`src/codex/retired-model-migration.ts`, shaped like the existing
+`runClaudeAuthModeMigration`, with tests for the three stored slugs, sibling-key
+survival, idempotence, and leaving any other model alone.
+
+## Verification and its limits
+
+The owner instructed mid-loop that the local suite must not be run on this machine; a
+baseline run confirmed why, reporting ~279 failures unrelated to this change. So
+`bun run typecheck`, `bun run test`, `bun run structure:check` and the dashboard lint
+are **NOT RUN locally**, and the evidence is repository CI against the final head.
+`bun run privacy:scan` and `tests/ci-workflows/repo-hygiene.test.ts` were run before
+that instruction arrived, on the devlog commit, and both passed.
+
+What this does not prove: nothing here exercised a live ChatGPT account. That the
+retired slugs now 404 upstream is the premise of the task, not something this unit
+verified.
+
+## What did not improve, and what would falsify this
+
+The `desktop-3p` 1M-native regression lost its positive control. `gpt-5.4` was the only
+native with a 1M window, so the test that proved a provider cap can take `supports1m`
+away now only proves no native ever gets it. If a 1M native returns, that test should
+regain a positive case rather than stay an absence check.
+
+The account-namespaced question turned out to be the real defect rather than a caveat,
+and it is now fixed and tested. What remains unproven is the disk side: a persisted
+`selector/gpt-5.4` row is no longer re-admitted as evidence, but
+`isUnsupportedOpenAiNativeSlug` still returns false for any slug containing `/`, so the
+stale row itself is not actively deleted from a user's catalog file. It stops being
+regenerated and stops being observed; whether it lingers in a file until the next full
+rewrite was not measured against a real installation.

-`gpt-5.6-sol`, `gpt-5.6-terra`, `gpt-5.6-luna`, and `gpt-5.4-mini`. Open `ocx gui` to replace or
+`gpt-5.6-sol`, `gpt-5.6-terra`, `gpt-5.6-luna`, and `gpt-6-astra`. Open `ocx gui` to replace or
 reorder up to five native or routed models. The dashboard can also set one preferred sub-agent model
 and reasoning effort. See [Sub-agent Surface](/guides/sub-agent-surface/) to choose v1/base/v2 and
 understand when guidance, native defaults, and fallback apply.

 ## Codex account warmup
 
-When a ChatGPT account is added or reauthenticated, OpenCodex normally verifies it before saving with a small streaming request to the Codex Responses backend. It waits for `response.completed`, defaults to `gpt-5.4-mini`, and retries with `gpt-5.5` and `gpt-5.6-luna` on HTTP 400 or HTTP 404. Public errors contain fixed failure categories rather than raw upstream response bodies.

Public errors contain fixed failure categories rather than raw upstream response bodies.
 
 If the new OAuth credential's authenticated usage lookup confirms an exhausted 5-hour, weekly, or monthly quota, the account is saved without this model request and shows **Validation pending**. It cannot serve pool requests, even after a restart or token refresh. Once quota recovers, **Refresh quotas** finishes validation: a fresh, complete usage reading with headroom permits one small model request, and only a completed response enables the account. Failed or incomplete readings and failed validation preserve the restriction. Passive account polling does not trigger deferred validation. Unknown usage during initial registration retains the normal warmup gate.

What changes is that automatic rotation stops choosing it, including when it is already the active account or already bound to a thread — which is the state a lapsed subscription leaves behind.
 
 Two deliberate limits. The main Codex account is never excluded by plan, because selection-only routing withholds its plan rather than reading the fenced native credential, so a rule covering it would disagree with itself. And when no unexcluded account remains, the excluded one still answers rather than failing closed; pausing every account is still the way to stop serving entirely. There is no `minimumPlan` counterpart, because ranking ChatGPT plans against each other needs a total ordering that does not exist here.

 意図的な制限が2つあります。メインの Codex アカウントはプランによって除外されません。選択のみのルーティングは保護されたネイティブ資格情報を読まずにプランを伏せるため、メインを対象にすると挙動が食い違うからです。また、除外されていないアカウントが1つも残らない場合は、失敗させずに除外済みのアカウントが応答します。完全に停止したい場合は従来どおり全アカウントを一時停止してください。`minimumPlan` に相当する設定はありません。ChatGPT のプランを順位付けするには、ここに存在しない全順序が必要になるためです。

Перезапуск и обновление токена не включают маршрутизацию. После восстановления квоты обновите её: полные свежие данные с доступной ёмкостью разрешают небольшой проверочный запрос. Только успешное завершение включает аккаунт. Ошибки сохраняют ограничение. Пассивный опрос не отправляет такой запрос. Неизвестная квота при регистрации требует обычной проверки.

 Два намеренных ограничения. Основной аккаунт Codex никогда не исключается по тарифу: маршрутизация в режиме «только выбор» скрывает его тариф, чтобы не читать защищённые нативные учётные данные, и правило для него противоречило бы само себе. А если не осталось ни одного неисключённого аккаунта, исключённый всё равно отвечает вместо отказа; чтобы остановить обслуживание полностью, по-прежнему нужно поставить на паузу все аккаунты. Аналога `minimumPlan` нет: чтобы ранжировать тарифы ChatGPT, нужен полный порядок, которого здесь не существует.

 İki kasıtlı sınır var. Ana Codex hesabı plana göre hiçbir zaman dışarıda bırakılmaz: yalnızca-seçim yönlendirmesi korunan yerel kimlik bilgisini okumamak için planını saklar, dolayısıyla ana hesabı kapsayan bir kural kendisiyle çelişirdi. Ayrıca dışarıda bırakılmamış hiçbir hesap kalmadığında, dışarıda bırakılan hesap başarısız olmak yerine yine yanıt verir; hizmeti tamamen durdurmak için hâlâ tüm hesapları duraklatmak gerekir. `minimumPlan` karşılığı yoktur, çünkü ChatGPT planlarını sıralamak burada bulunmayan bir tam sıralama gerektirir.

Local CLI/tray callers first attest the exact runtime PID and port, then send a process-scoped HMAC capability bound to that method, path, PID, and port; the capability authorizes no other management route and is invalid after replacement. The caller observes one absolute deadline and accepts success only after a different runtime PID is healthy on the same port. `GET /api/system/health` is the authenticated scalar-only identity used by shared-plane Dashboard status and restart reconnect polling; it does not widen a Remote Hub management ingress to unauthenticated `/healthz`. `GET /api/system/memory` — service-process runtime/memory identity (pid, Bun version/revision, optional `bunRuntimeSource` provenance, platform, RSS/heap/external/ArrayBuffers scalars, observed memory = max(RSS, external, ArrayBuffers), `bun:jsc` heap context, streamMode + eager-relay gate decision, watchdog snapshot sliced to the last 60 samples) plus privacy-safe `appOwnedBytes` retained-store totals/counters under static store ids. Its response-state block also reports spill-write `initial`/`healthy`/`degraded` status, a consecutive-failure streak, fixed error class, and failure/success timestamps. A successful publication clears the streak in the same process; raw error text and paths never enter this surface. Scalar-only payload; dashboard/admin callers use the standard management gate, while `ocx doctor` may use only the exact process-scoped local-read capability. It must never move to unauthenticated `/healthz`. |
 | Stop | `POST /api/stop` — restore native Codex, stop any installed service, and exit the proxy. |
 | Diagnostics/sync | `src/server/management/config-routes.ts` — `GET /api/diagnostics/project-config` reports project-level Codex config that bypasses managed routing; `POST /api/sync` re-runs catalog/config sync. The diagnostic reports the bypass; it does not rewrite the project file. |
-| Sidecar/shadow-call settings | `src/server/management/config-routes.ts` — `GET/PUT /api/sidecar-settings` and `GET/PUT /api/shadow-call-settings`. PUT accepts model and backend (web-search union: openai/anthropic/xai/gemini/exa; xAI is live through stored Grok OAuth, while Gemini/Exa remain inert until their executors ship) plus validated `webSearch.xSearch`, optional `webSearch.exaApiKey` (write/clear only — never echoed by GET or the PUT response; redact.ts strips it from logs), `webSearch.reasoning`, `vision.reasoning`, `vision.enabled`, `vision.maxDescriptionsPerTurn`, and `vision.timeoutMs`; the read and PUT-response payload reports model, backend, reasoning, enabled, the vision per-turn limit, and timeout. `timeoutMs` is validated against the runtime integer bounds in `src/vision/timeout-bounds.ts`. Provider/OAuth credentials live in their stores; `exaApiKey` is the one sidecar-owned secret and follows the write-only contract above. Both shadow-call responses also report the resolved `sourceModels` — the prefixes the runtime actually intercepts (`src/lib/shadow-call.ts`, default `gpt-5.4-mini` + `gpt-5.6-luna`), so no client hard-codes a helper slug that a Codex release can invalidate. |
