fix(kiro): keep usage evidence across restart and refuse ARN-less probes - #5967
Conversation
Research inventory (001), plan with audit record (000), diff-level decade docs 010-070 for the stacked layers, and the method (080) for the landed-tree result.
Kiro quota rows and the exhaustion verdict now persist beside the shared account-quota snapshot and hydrate before the first routing read. Each row carries a hash of the account's login identity (a loginId written on every login and kept across refresh), so evidence never outlives the credential it was measured for. Every Kiro routing read goes through kiroAccountEvidence, which bounds the quota bar and the verdict by their own TTL and reset. A probe that cannot form a profile ARN sends nothing, and a failed probe keeps the last good verdict instead of turning an overage account into an exhausted one.

Merge Risk: 🟡 Moderate · up to This update only swaps a test fixture's provider name and does not change production behavior. Several previously flagged concerns about Kiro quota hydration, stale probe results, and planned-but-unimplemented refusal/rotation behavior in the parity documents remain unresolved and should be addressed before this stacked change is considered fully mergeable. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new login-bound evidence and shared-cache handling appear to preserve account and provider separation.

When a spent account returns a missing or newly introduced overageStatus, this expression records exhausted: false rather than an unknown verdict. rankAccountsByHeadroom treats any explicit false verdict as authoritative and overrides the 100% quota bar, while preferredInitialAccount keeps such an active account, so requests can continue selecting an account that is actually exhausted. Preserve the verdict as unknown unless the status is explicitly ENABLED or DISABLED; the quota bar can then rank the account last without excluding it.
Useful? React with 👍 / 👎.
…d row The Anthropic rate-limit tests used a Kiro row as an arbitrary other provider. Kiro rows now require a matching login identity, so the fixture moves to zai, which keeps the plain row contract these assertions are about.

🌐 Web query:
Does AWS document that a Kiro generation request to runtime.{region}.kiro.dev was not processed when it returns HTTP 502, 503, or 504, or provide an idempotency mechanism for safely replaying that request to q.{region}.amazonaws.com?
💡 Result:
**No—not in the public AWS/Kiro documentation I found.** AWS documents `runtime.<region>.kiro.dev` and `q.<region>.amazonaws.com` as Kiro endpoint names, but I found no documentation saying a generation request that receives HTTP 502, 503, or 504 definitely **wasn’t processed**, and no documented idempotency key or other mechanism to make replaying it to the `q` endpoint safe. ([kiro.dev](https://kiro.dev/docs/privacy-and-security/vpc-endpoints/?utm_source=openai))
So a gateway error alone shouldn’t be treated as proof the request had no effect; replaying could duplicate work. The endpoint documentation establishes connectivity, not retry or delivery semantics. ([kiro.dev](https://kiro.dev/docs/privacy-and-security/vpc-endpoints/?utm_source=openai))

Resolve replay safety before enabling alternate-host retries.
The planned inspectEndpointHttpFailure branch sends the same generation request to q.* after a canonical-host 502, 503, or 504. The before-output restriction only shows that no Kiro event bytes were received. It does not show that the first host did not process the POST.
The plan identifies this as an upstream side-effect risk. The send budget limits attempts but does not prevent duplicate generation or other upstream side effects. Establish that the Kiro endpoint supports safe replay, or add an idempotency mechanism before sending to the alternate host.

Define equal-observedAt behavior for both verdict writers.
The callers pass Date.now(), which has millisecond resolution. Two events for one account can therefore receive the same timestamp. noteKiroMonthlyRefusal ignores an equal observation because it checks same.observedAt >= observedAt. noteKiroServedSuccess clears exhaustion only when old.observedAt < observedAt. Equal-time events therefore preserve the existing verdict.
The plan states that newer observations win, but it does not define or test the equal-time policy. State that equality is first-writer-wins and add regression coverage. If processing order must win, add a deterministic sequence or explicit equal-time last-writer rule.

Persist a retry deadline after a cold-cache failure.
When no good row exists, old is undefined, so this branch stores no failure deadline. The finally block removes the in-flight entry at Line 138. The request-transport warm-up at Line 187 can then start another POST for every later model request while the management endpoint continues to fail. This adds repeated timeouts and load during an outage. Track a retry deadline for the current identity even when no last-good list exists, while keeping membership undefined until a valid list arrives. Add a regression test that verifies a second call within FAILURE_RETRY_MS does not send another POST.

Keep Kiro 429 recovery active when the preference switch is off.
These lines say oauthAccountFailover.enabled: false disables refusal rotation. The supplied current account reference says this setting disables only pre-dispatch account preference; Kiro 429 recovery remains active. If this plan is implemented as written, a 429 can reach the caller even when another eligible account could serve the request. Preserve reactive 429 recovery when the setting is false, and update the planned assertions and translations to keep this distinction.

Reject redirects before sending OAuth secrets.
The postJson sketch sends clientSecret or deviceCode in the request body at Lines 154-156, but it does not set a redirect policy. Bun fetch follows redirects by default. A 307/308 preserves the POST body, and Fetch permits HTTP(S) redirect targets. If an upstream endpoint redirects to an attacker-controlled origin, that origin can receive the secrets; an HTTP redirect also removes TLS protection for that hop. (bun.sh)
Set redirect: "error" on credential-bearing requests.

| Add a type-only `ProviderAccount` import from `./types` and `kiroAccountEvidence` from `../providers/kiro-usage`; never read Kiro quota through `isAccountQuotaExhausted` or a raw cache in this projection. Pass each existing roster account from `eligibleIdsIn` and management `projectAccounts`, with no `getAccountCredential`/`loadAuthStore` per projection call. Unknown evidence yields `{ autoSelectable: true }`; overage-enabled at 100% remains auto-selectable. This is candidate eligibility at observation time, not a promise that a later lease/send succeeds. 040's transient lease cap is outside the projection and has no `skipReason`; 050's model membership is a preference, not a skip reason. Proactive least-loaded ranking and preferred initial-account selection run only under effective pool enablement. 030 refusal-aware first-admission exclusion of a *known* suspended/monthly-exhausted active account runs when `oauthAccountFailover.enabled` is unset (presence-is-consent default) or true. An explicit global or per-provider `false` forbids both an account move at first admission and refusal rotation (`src/server/responses/adapter-dispatch.ts:852`); it wins over a known exclusion. When movement is permitted, initial selection tries another eligible account; a singleton or all-excluded pool still sends to the active account, even if its row says `autoSelectable:false`. The configured `maxConcurrentPerAccount` cap is independently opt-in: at a full cap, try another eligible account when movement is permitted; if movement is disabled or this is a singleton, wait only the bounded interval and then return retryable HTTP 503, code `account_capacity`, with `Retry-After`. 030's `rotateGenericOAuthAccountOnRefusal` owns the sole bounded retry loop; 040's capacity exclusion feeds that loop. Keep the original refusal `Response` intact until a replacement is admitted; if none is admitted, return its original status/body to the client. For Kiro 429/400/403, including the run-turn 429 arm at `src/server/responses/run-turn-execution.ts:371` reached through `_kiroAuthContext` at :61, classify with `classifyKiroRefusal` and use this same rotation function. Kiro-only retain-until-admission ordering and `genericFailovers` accounting must not change non-Kiro order/counts; test adapter-dispatch and run-turn 429 arms for non-Kiro. No second rotation loop is introduced here. |

Preserve Kiro 429 recovery when failover preference is disabled.
The current contract in docs-site/src/content/docs/reference/cli/providers-accounts.md says oauthAccountFailover.enabled: false disables pre-dispatch account preference, not Kiro 429 recovery. Line 296 instead disables refusal rotation. The plan repeats this behavior at lines 375, 387, 390, and 487.
If implemented, this change can leave a request on a rate-limited account and return its 429 even when another eligible account exists. Keep false limited to pre-dispatch preference, and align the repeated rules and tests with the documented 429-recovery behavior.

Validate customWindows before searching it.
If a persisted Kiro row has a valid identity and quota fields but contains customWindows: [null], src/providers/quota/account-cache.ts admits the row during hydration. The callback then reads window.label and throws. A non-array customWindows value also makes .find throw. The first routing read fails, and diskHydrated prevents a later hydration retry. Require an array and check each element before reading its fields.
As per coding guidelines, “Optional integrations must degrade through the existing failure representation rather than crash the request path.”

Reject a Kiro probe result when its login identity has changed.
If an account logs in again to the same slot while Line 457 awaits the usage request, kiroProbeCurrent rejects the cache write at Line 498. fetchAccountQuota still returns the old snapshot at Line 503. fetchProviderAccountQuotas then presents that quota under the replacement account’s ID. Apply the identity check to the returned result as well as the cache write. Return an unavailable result, or reread for the current identity. Apply the same rule to the unavailable and catch paths at Lines 487 and 514.

Set kiro.authType in the Builder ID fixture.
normalizeCredential does not persist authType, so kiroUsageContextForAccount receives undefined. The resolver then does not select the Builder ID fallback, while the test expects builderIdFallback to be true.

The #5967 identity/freshness guard rightly rejects a verdict whose observedAt is later than the supplied read clock. Cooldown tests captured that clock before seeding the verdict, so a millisecond tick in a multi-file run made them read their own fixture as future evidence. Capture the read time after the seed, and compare the in-window reset against that read time. Red: usage-restart plus pool-rank failed the distant-reset assertion with a forced 2ms boundary. Green: the same two-file run passes all 31 tests; account-state-disk plus pool-rank passes 43.

Summary
Kiro forgot everything it knew about account quota on every restart. The generic quota snapshot on disk was only hydrated for Anthropic and the Kiro probe never wrote to it, so after a restart the pool routed Kiro accounts blind until something re-probed each one. A Builder ID or social probe that could not form a profile ARN also still sent a request and ate a 400.
After this change:
kiroAccountEvidence(account), which bounds the quota bar and the verdict by their own TTL and reset. A 100% bar with no verdict ranks last but is never treated as exhausted, because an overage account keeps serving.loginIdon every login (kept across token refresh), and rows carry a hash of it. A re-login into the same slot, including the legacy identity-less upgrade, starts clean.This is layer 010 of the plan in
