fix(catalog): keep Codex's auto-review model so reviews stop falling back to the task model - #6727
Conversation
…back to the task model The canonical native catalog dropped codex-auto-review as an unsupported bare Codex slug. Because model_catalog_json replaces Codex's entire catalog, the approval reviewer could no longer find its preferred model and fell back to the parent task model at Low effort. Share the exact control-plane id set with routing and preserve or separately backfill one hidden reviewer row whenever native OpenAI rows are included. Keep its upstream reasoning metadata and exclude it from native synthesis, account clones, picker ordering, public lists and override stamping. Preserve provider/per-model/root reviewer precedence and non-OpenAI fallback behavior. Cover all catalog writers, persisted duplicates, visibility, Low effort, HTTP model lists, shared routing and override selection. Register the new regression file in both layout inventories and document the contract.

The new exception makes the linked provider guide inaccurate: docs-site/src/content/docs/guides/providers.md:1354 still says the root auto_review_model applies to “every row,” while this change deliberately leaves codex-auto-review unstamped. Update that directly affected workflow page to say task rows and describe the hidden-row fallback, so operators do not receive contradictory configuration semantics from two canonical English pages.

✅ Deterministic PR hygiene checks passed. |
Project the internal reviewer before multi-agent mode normalization so explicit v2 and native v1 exceptions apply in both catalog builders. Keep it outside account clones, featured/picker ordering and effort synthesis. Require an ordinary bare native OpenAI row in the final catalog before preserving or backfilling a reviewer. Hidden natives count; Reserve, account-only and native-less catalogs do not. Prune persisted orphan reviewers after effort clamps and preserve the missing-pin skip fallback. Add regression coverage for mode projection, suppressed/Reserve-only native sets, account-only catalogs and orphan cleanup. Keep the three CI-failing tests and their expectations unchanged.

Preserve codex-auto-review’s v1 pin in default multi-agent mode.
codex-auto-review is not a reserve projection, so isReserveCatalogProjection does not preserve it. The row reaches the default fallback in applyMultiAgentMode, where multiAgentV2Enabled changes its existing v1 pin to v2.
Extend the preservation callback for this control-plane row. Do not add it to UPSTREAM_NATIVE_ENTRIES; that map authorizes persisted native-row replacement.
🐛 Suggested fix
- preserveDefaultMultiAgentVersion: isReserveCatalogProjection,
+ preserveDefaultMultiAgentVersion: entry =>
+ isReserveCatalogProjection(entry) || entry.slug === "codex-auto-review",Add a default-mode assertion beside the explicit-mode tests.

Summary
With Auto-review enabled, Codex chooses its approval reviewer by looking up
codex-auto-reviewin the loaded catalog. When that row is missing and no reviewer override is set, Codex falls back to the parent task model at Low effort (select_review_modelin codex-rsext/guardian-reviewer/src/model.rs, unchanged on upstreammainat ec8251c54). OpenCodex writesmodel_catalog_json, which replaces Codex's entire catalog, and every canonical catalog writer droppedcodex-auto-reviewas an unsupported barecodex-slug. So reviews through OpenCodex ran on the task model (the report shows GPT-6.1 Sol / low) instead ofcodex-auto-review/ low.The drop dates from 13c03e6 (v2.6.2), which removed legacy rows that were persisted with
visibility: "list"and showed up in the picker. This change keeps that goal and restores the reviewer:codex-auto-review) now lives insrc/codex/control-plane-models.ts. The router imports it instead of keeping its own copy (fix(router): pin Codex auto review to OpenAI #833 already routes this id to canonical OpenAI).codex-auto-reviewrow withvisibility: "hide". A persisted or live row is reused when present; otherwise the row is backfilled from the pinned upstream snapshot. It keeps upstream's own reasoning ladder, so Low is advertised, and it goes through the same multi-agent version projection as the other native rows. A later effort clamp that removes every ordinary native row also removes it./v1/models, and reviewer-override stamping. Provider, per-model, and rootautoReviewModeloverrides keep their precedence.Closes #6712
Not changed here: Codex only generates the
x-codex-guardianmarker,parent_response_id, andguardian_credits_requestedwhen its base URL ends in/backend-api/codex. OpenCodex injects a/v1base URL, so those markers are never produced on this path, and forwarding them would need a separate design. This PR does not forward or synthesize any reviewer marker. Whether a marker-lesscodex-auto-reviewrequest is billed like a native review is not established.Verification
