fix(codex): throttle repeated failed pool quota primes - #3003
Conversation
A pool account whose WHAM lookup fails stores no quota, so it stays "unknown" and every later prime trigger re-selects it as stale and repeats the same failing request. Successful lookups are already bounded by POOL_CACHE_TTL; failures had no backoff at all. Record the last prime attempt per account and give a failed lookup the same TTL window. The record is keyed by credential generation, so a re-authentication, refresh, or account removal retries immediately instead of waiting out a backoff earned by the previous credential.

When all 16 quota-flight slots are occupied, this records an attempt before fetchPoolAccountQuota reaches its admission check and throws PoolQuotaProbeBusyError at src/codex/auth-api.ts:1051. The prime correctly swallows that transient busy result, but every subsequent startup/pre-route trigger then skips this still-unknown account for the full five-minute TTL even though no WHAM request occurred, potentially prolonging the all-unknown routing state. Record the backoff only after admission succeeds, or remove this entry when the probe is rejected as busy.

For an expired credential, getValidCodexToken can refresh it and increment its generation after this value is captured. If the subsequent WHAM request fails, no quota is stored, and the next prime sees this stale attempt generation differ at line 1182 and immediately issues another failed request inside the TTL window. Persist the credential generation returned by fetchPoolAccountQuota after the attempt resolves so token refreshes do not accidentally invalidate the backoff they just earned.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Record the generation used by the quota request.
Line 1212 captures the generation before fetchPoolAccountQuota() runs. That request can refresh credentials and increase the generation before it sends the WHAM request. If that refreshed request fails, the next prime pass sees a generation mismatch and sends one immediate duplicate request instead of applying the failed-lookup backoff.
Update the attempt record with PoolQuotaResult.credentialGeneration after the request settles. Keep the pre-request record only for thrown requests. Add a regression where credential refresh changes the generation and WHAM returns 503; the next prime pass must keep the call count unchanged.

Summary
A Codex pool account whose WHAM quota lookup fails stores no quota. It therefore stays "unknown", and
primeCodexPoolQuotasre-selects it as stale on every later trigger and repeats the same failing request. Successful lookups are already bounded byPOOL_CACHE_TTL; failures had no backoff at all.The practical effect shows up in a pool containing one unreachable, rate-limited, or rejecting account: startup priming, lazy pre-routing priming, and dashboard reads each re-issue the same doomed upstream call instead of once per TTL window.
This records the last prime attempt per account and gives a failed lookup the same TTL window a successful one already gets.
The attempt record is keyed by credential generation, so the throttle cannot hide a recovery: re-authentication, a refresh, or account removal bumps the generation and retries immediately rather than waiting out a backoff earned by the previous credential.
Scope is deliberately one filter branch, one attempt record, and its test-only reset. Routing, scoring, quota parsing, and the single-flight contract are unchanged, and a successful lookup behaves exactly as before.
Verification

Checklist
Docs: no user-facing behaviour or configuration surface changes, so no docs or release-note update applies.
POOL_CACHE_TTLis unchanged and the throttle is internal to priming.Security: the attempt map holds only a local account id, its credential generation, and a timestamp. No tokens, no new identifiers, nothing added to logs, and nothing persisted to disk. The generation key is what keeps the throttle from becoming a stale-credential trap.
