authenticated access program metadata. Bare models use the main Codex account; account-qualified
models use their selected account. Refreshing the integration updates these rows when upstream
changes the account's access programs.
OpenCodex carries the logged-in main account's live model availability prompt onto bare native model rows.

State when a bare native row receives a prompt.

A bare native row receives a prompt only when a confirmed main-account roster lists the model and supplies a valid message. Otherwise, src/codex/catalog/access-programs.ts writes null. Qualify this sentence so users do not expect a prompt on every bare native row.

As per coding guidelines, “Document current shipped or intentionally pending behavior.” As per path instructions, “Check that user-facing docs stay in sync with actual CLI/API behavior.”

Qualify the sentence about bare native model rows to state that OpenCodex
carries a prompt only when a confirmed main-account roster lists the model and
provides a valid message; otherwise, the prompt is null.

The proxy exposes one bare `openai` Codex-login route with Pool(default) and Direct account modes,
plus `openai-apikey/<model>` for the configured API key. Pool includes main plus added accounts;

Retirement is a catalog/evidence policy, not a universal request denylist. Manually supplied model ids still follow generic routing. User-selected config and historical usage remain stored.

Account-gated native ids use authenticated ChatGPT `/models` rosters cached per credential generation with a bounded timeout.
A bare gated row requires a confirmed eligible account; a selector-qualified row requires its mapped account. Failed discovery
grants neither. The same snapshot gates Pool selection, so catalog and runtime use consistent account evidence.
The roster's per-model `available_access_programs` is projected separately: bare native rows use only confirmed main-account
metadata, and selector-qualified rows use only their mapped account. An object requires a valid `cyber` string array; malformed values under other program keys are omitted without losing that grant. Explicit `null` stays null; omission stays omitted.
Failed discovery or credential replacement removes stale access-program metadata. It changes presentation, not routing grants.
The roster's `availability_nux.message` is trimmed, capped at 2,000 UTF-16 units without leaving a lone surrogate, and projected only onto bare native rows from a confirmed main-account roster that lists the slug. Missing or unconfirmed main metadata writes `null` to clear stale prompts; account-qualified, combo, and native alias rows carry no availability prompt. Pool-account prompts never reach the bare row.

`client_version` arrives on the inbound request and is part of that cache identity, so
`src/codex/model-entitlements.ts` bounds the work as well as the state: stored versions per account, concurrent
