In `@src/codex/model-entitlements.ts`:
- Line 725: Move the admitVersionMiss call in the version-admission flow to
after the flight-capacity guard, so versions rejected for capacity do not
consume miss allowance. Add a regression test that holds four flights open and
verifies the capacity-rejected version does not consume allowance.
In `@structure/catalog.md`:
- Around line 84-85: Update the inline code span in the documentation so the
full source path `src/codex/model-entitlements.ts` remains on one source line
without an embedded newline or whitespace.

Marking ready for review as maintainer. The four-box contributor checklist includes a local-CI attestation that a fork author cannot satisfy, because fork contributors cannot start repository CI. I approved the Cross-platform CI and React Doctor workflow runs at this exact head (run 34794874697) and they came back green, which is the evidence the checklist was standing in for. Reviewed the diff before approving: the change bounds completed entitlement version misses per account in src/codex/model-entitlements.ts, adds the focused regression in tests/codex-integration/codex-model-entitlements.test.ts, and records the new bound in structure/catalog.md. Merging into dev under the single-maintainer dev integration clause in MAINTAINERS.md. |

When an authenticated /v1/models caller knows the trusted runtime version and primes four distinct non-runtime versions, the account has five admitted keys but boundedCacheSet retains only four. Cycling through the trusted version and those four charged versions then makes each insertion evict the next key; the four caller versions remain alreadyCharged, while the trusted version bypasses admission, so every sequential request can launch another authenticated fetch under every stored account, defeating the completed-work bound. Reserve cache capacity for the exempt key or reduce the charged-version allowance, and cover the cycle with a credential whose identity passes the cache-write fence.

Summary
client_versionarrives on the inboundGET /v1/modelsrequest and is part of the gated-roster cache identity. The existing budgets bound stored state and concurrency, so a caller that cycles the value and waits for each answer misses the cache by design, misses the flight key by design, and renews an authenticated upstream/backend-api/codex/modelsrequest under every stored account token for as long as it likes. The gated-model checks it displaces fail closed while that happens.Bound the completed work as well: at most four distinct caller-selected versions per account may open an upstream request within one roster window. Flight capacity is checked first, so an attempt rejected without starting a request consumes no version allowance. Over the bound the answer is unconfirmed, the same fail-closed shape a discovery failure already produces.
Two details matter for legitimate traffic. Distinct versions are counted rather than attempts, so one client retrying a single version through an upstream outage keeps coming back on the 15-second failure TTL instead of spending the whole allowance and locking itself out for the rest of the five-minute window. The locally selected runtime version is never charged, so its refresh survives an untrusted caller spending everything else.
The budget is keyed by account, not by credential identity. A Pool access-token refresh increments the generation, so an identity-keyed map would gain a permanent row per generation for the life of the process; a generation change replaces the row instead, which is also the right semantics for a new credential. Direct callers keep their existing behavior: their account id is derived from their own forwarded token, so they cannot reach another account.

Review readiness evidence
Published head:
1be399ae938f67bfbd823a2715c7e3f91fa0966e. This follow-up fixes both latest CodeRabbit findings without rebasing: capacity admission precedes miss charging, and the inline source path is intact.The held-flight regression fails on the preceding head and passes after the fix. Local verification on this published head: 53 entitlement tests pass with 234 assertions; typecheck, structure:check, privacy:scan, and diff checks pass. This focused evidence is not a claim that the full suite passed.
Cross-platform CI 34803014163 was dispatched once for this exact head. Full readiness remains pending its result; no old-head CI result is substituted. Known base Windows defects are handled separately in #4564 and #4568 and will be attributed from this run's actual failures if they recur.
