The ChatGPT Codex backend and the OpenAI API serve gpt-6-sol, gpt-6-luna,
gpt-6-astra and gpt-6.1-sol, but the reasoning, Chat Completions and vision
gates only knew the gpt-5 line. A gpt-6 model got no reasoning control and
no real "off", went out on the legacy wire with max_tokens and a
temperature that reasoning models refuse, and was denied image input.
The three gates now read one classifier, openai-model-family.ts, so a new
generation is taught in one place. Every GPT from 5.1 on, the gpt-6 line
included, is the family that takes effort "none"; every GPT from 5 on reads
images. The upstream catalog (codex-rs/models-manager/models.json) lists
image input for every gpt-6 slug and the same reasoning presets as the
gpt-5.6 line; the presets omit "none" for gpt-5.5 too, which accepts it.
The Codex slug ladder moves into codex-slug-chain.ts and gains gpt-6-sol,
gpt-6.1-sol and gpt-6-luna. gpt-5.6-terra stays first as the slug verified
against the backend; the catalog names gpt-6-sol as its upgrade, and a
rotation retires a whole line at once, so the gpt-6 rungs follow before
terra's own siblings. The ladder test now holds every rung to a recognised
reasoning family with a real off and image input. The OpenAI presets offer
gpt-6.1-sol and gpt-6-luna.
The ChatGPT Codex backend now rejects every slug from gpt-5.5 down, so a
deploy without a CODEX_MODEL_FALLBACK_CHAIN override walked the whole
default ladder into "all configured Codex slugs were rejected". The
default now starts at gpt-5.6-terra, with its luna and sol siblings and
gpt-5.5 as the last rung.
The gpt-6 line stays out of the default: the reasoning, sampling and
vision gates do not recognise that family yet, and a test now holds every
default slug to a family the reasoning gate knows.
- docs/README.md: drop the doctor-report.md and audit/ entries (neither
exists), broaden the ops/ description, list the real subdirectories,
and stop promising release-by-release migration notes
- migration/v1.3-to-v1.4: note which v1.4 routes have since moved or
gone; rotation runs via pnpm dlx tsx
- ui-guidelines: six locales with guard tests, settings sections point
at the registry instead of an eight-item list, /settings redirect is
a 308
- apple-store-connect-checklist: drop the unsourced 40% rejection-rate
figure
- codex-protocol-spec: the slug chain rotated on 2026-06-02; default is
gpt-5.5, the shipped constant is authoritative
Retroactive cleanup of CHANGELOG.md and docs/audit/v1.4.X-summary.md
files. Removes maintainer's real name, specific health figures tied to
the live tenant, internal release-process jargon, and stray German
strings in English-only release notes. Pre-release PII-grep gate added
to the v1.4.20 release pipeline. No git history rewrite.

Bumps version to 1.4.15 and adds the corresponding CHANGELOG entry
covering backup completeness, achievements UI, onboarding tour,
doctor-report v2, auto-deploy on GHCR push, empty-states sweep,
notification + integration status UI, AI hallucination guardrails,
mobile UX fixes, and the BD-Zielbereich percentage fix.
Includes the formatting drift left over by the v1.4.15 development
phases (Prettier sweep on touched files) and a typecheck fix in
`dashboard-layout.test.ts` so `pnpm typecheck`, `pnpm lint`,
`pnpm format:check`, `pnpm test`, and `pnpm test:integration` all
pass green on the release tag.

Phase C1 (v1.4.15) — slug-drift defence per Marc's hard mandate:
"Die Integration des Slug Drift Risiko darf halt immer überhaupt nicht
sein." ("Slug-drift risk must NEVER happen.")
Background: the ChatGPT-Codex backend rotates its allow-list silently.
v1.4.7..v1.4.13 lost a week to chasing the rotation manually
(`gpt-5-codex` → `gpt-5.3-codex`). A single hard-coded `CODEX_MODEL`
flips invalid the moment upstream rotates it.
Solution — the client now walks an ordered fallback chain on every
fresh request series and caches the first slug that returns 200 +
`response.completed` for 1 hour. Subsequent requests skip the chain
walk entirely on a cache hit.
Spec: extends `docs/codex-protocol-spec.md` with new §7b documenting
the chain semantics, cache TTL, walk triggers (400 + "not supported
when using Codex with a ChatGPT account" / `model_not_found` /
"does not exist" / 404), non-walk responses (5xx, 429, 401-with-
refresh, `invalid_prompt`), and the all-failed structured-503 error
shape. Per Marc's v1.4.6 hard rule ("read source-of-truth before
iterating; no more 6-iteration line-fixes"), the spec was extended
FIRST and the implementation cross-referenced against it.
Implementation:
- New `src/lib/ai/codex-slug-cache.ts` — process-local positive
cache. Single-slot Map (per-account scoping is a one-line change
when v1.4.16 multi-tenant rolls out). 1 h TTL. `getCachedCodexSlug`
auto-evicts expired entries on read.
- Rewritten `CodexClient.generateCompletion()` — walks the chain
`[cached?, ...slugChain]` in order. On 401 → refresh + retry SAME
slug (auth ≠ slug-state). On 400/404 with rejection body → drop
cache, walk to next. On 5xx/429 → propagate immediately (walking
won't help). On all-rejected → throw structured 503 with
`attempted[]` list, `httpStatus: 503`, message "AI provider
unreachable — all configured Codex slugs were rejected".
- `CodexAttemptDiagnostics` exposes `{ attempted, cacheState,
workingSlug }` for Wide-Event annotations the route can read via
`client.getLastDiagnostics()`.
- `CODEX_MODEL_FALLBACK_CHAIN` env override (comma-separated). When
`CODEX_MODEL` is also set, it folds into chain position 0; the
default chain (`gpt-5.3-codex` → `gpt-5-codex` → `gpt-5` →
`gpt-4o`) survives behind it. Stable de-dup.
Tests: +20 across 2 new files.
`codex-slug-cache.test.ts` (7 tests) — TTL-edge boundaries,
invalidation, replacement semantics.
`codex-slug-fallback.test.ts` (13 tests) — cold-cache happy path,
walk on canonical 400 body, walk on `model_not_found`, walk on 404,
no-walk on 500/429/401, all-rejected → 503-with-attempted-list,
cache-hit shortcut, cache invalidation on rejection, isSlugRejection
body classifier, loadFallbackChain env-pin merge.
The 5 existing `codex-client.test.ts` cases continue to pass without
edit — the new `slugChain` constructor parameter is opt-in and the
single-slug behaviour reduces to chain length 1.
Tests: 1028 → 1048 unit pass (+20). Typecheck clean for AI files.
Lint clean.

Picks up the prettier line-wraps the v1.5 phase-1 planning docs and
codex-protocol-spec.md missed, and brings the redact.ts + insights
generate route test into the project's standard form. No behaviour
change — pnpm format:check now passes clean.

v1.4.13 swung from gpt-5-codex to plain gpt-5, but the chatgpt.com
backend rejects both with the same error:
{"detail":"The 'gpt-5' model is not supported when using Codex with
a ChatGPT account."}
The accepted slugs come from the bundled `models.json` in
`codex-rs/models-manager/` — neither `gpt-5` nor `gpt-5-codex` is in
the current bundle. `gpt-5.3-codex` IS in the bundle and is available
on Plus/Pro plans (per `available_in_plans`); verified live against
Marc's account today.
Operators can still override via `CODEX_MODEL` env var if they're on
a different plan tier.
Spec updated with §7a documenting the chatgpt-account-auth allow-list
constraint — the lesson is that the model_migration.rs slug references
are migration *prompts*, not wire slugs. Always cross-check
`models.json`.

Stop iterating on individual 400 errors and implement the full Codex
Responses-API protocol once, from the source. Wrote a 713-line
reference at docs/codex-protocol-spec.md from the official
openai/codex Rust client; this commit is the TS implementation
against that spec.
Required pieces that were missing in v1.4.11:
- `ChatGPT-Account-ID` header — extracted from the `chatgpt_account_id`
claim of the OAuth id_token (also accepts the URI-namespaced
variant under `https://api.openai.com/auth`). Without it: 401.
- `originator`, `User-Agent`, `Accept: text/event-stream`,
`session_id`/`session-id` (both spellings), `thread_id`/`thread-id`.
- Body fields `reasoning: null` and `include: []` are required even
when no reasoning is requested.
- Model slug is `gpt-5-codex`, not `gpt-5.3-codex` (the latter is a
test placeholder upstream).
- Refresh endpoint takes a JSON body, not form-urlencoded.
Storage codec rewrite: `codexAccessTokenEncrypted` now holds an
encrypted JSON blob `{ accessToken, accountId, expiresAt }` instead
of just the raw access token, so the account id stays available
across requests. v1.4.7-v1.4.11 records that lack the field cannot
be revived — `decryptCodexCreds` returns null for those rows and
`resolveCodexProvider` flips the connection to `expired`, prompting
the user to re-link once.
Removed the dead browser-flow routes (`/api/auth/codex/authorize`
and `/callback`). They never worked on hosted domains because
Hydra's redirect-URI allow-list for the public Codex client ID
covers only localhost; device-code is the only viable path.
CodexClient SSE parsing extended to handle `response.failed` and
`response.incomplete` terminal events, and to read the actual
routed model from the `OpenAI-Model` response header.
Tests rebuilt: codex-oauth covers the full device-code flow with a
synthesised id_token JWT, the JSON-body refresh, and the
storage-codec round-trip. CodexClient tests carry an `accountId`
through the constructor. All 720 tests pass; typecheck clean.
Refs: docs/codex-protocol-spec.md §1-§6 for every claim.
