What

On a Codex usage_limit_reached failure, AgentSession#markFailedCredential resolved the session's credential before marking it. That resolution re-runs the pre-request usage check, and once the cached usage report already reads exhausted (the status-bar poll refreshes it on its own clock), the check blocks the exhausted row and silently moves the session's sticky pointer to the next healthy row. markUsageLimitReached then blocked the healthy row for its default 60 s backoff, reported no remaining credential, and with default settings (no retry.* key) the turn surfaced the raw Codex error event: The usage limit has been reached (code=usage_limit_reached) with no replay, while the row that actually failed stayed unmarked.

  • AuthStorage.markUsageLimitReached gains an optional rowId that targets a stored row directly instead of the sticky pointer, and both paths locate the target again after the usage-report await (a snapshot that removes or reorders a preceding row meanwhile shifts indexes and drops the provider's session pointers; a vanished row marks nothing and returns false).
  • #markFailedCredential reads the row the session used, marks it first and by id, and only then resolves; rotation is proven by stored row id rather than key equality. The auth branch is unchanged and keeps its own resolve-then-compare proof. Rebasing onto current dev moved this onto the rewritten function, which added a credential trigger class (facts.credentialModelUnavailable) that also blocked a row through the sticky pointer, so that class now takes the same marked-by-id path. It keeps its getSessionCredentialType precondition, which like the row id is a synchronous read of the pointer, and it keeps the default backoff instead of the response's retry-after, exactly as before. The pre-resolve that used to run for every class now runs only in the auth branch, which is the one that needs the active key.

Why

Observed on 0.16.4 in a --prefer-credential session with two OAuth accounts: the failing message was content-free with transportFailure.providerCode = usage_limit_reached, nothing replayed, and the session sat on the error although the other account had its full quota. Instrumented, the mark step read active=TOKEN-B remaining=false after=TOKEN-B.

Testing

  • Exact-head affected-path CI for d2153419694b905c714f32b1503077b68f22fba8 passed the row-ID regression, credential-rotation mid-turn test, AI package check, native build, CLI smoke, state gates, and the other selected test shards. The coding-agent package-check job ended after a 45-minute runner setup timeout with no test step executed; this is runner infrastructure evidence, not a code diagnostic.
  • Local rebased candidate b48a7ff65526a90e08f199e6fb400d4d97d1398b includes current origin/dev 54e8cc3f8c517b0afe71eb0cccbabcb2872197d9 as a parent and preserves the six-file PR diff. bun test packages/coding-agent/test/auth-storage-mark-row-id.test.ts packages/coding-agent/test/credential-rotation-midturn.e2e.test.ts passed 23 tests; focused trigger coverage passed 93 tests; bun --cwd=packages/ai run check and bun --cwd=packages/coding-agent run check passed.
  • The current verdict remains needs-human because no authenticated independent approval exists on the exact head. The prior probepark approval is stale at 196bffd6e30c410f924435240090685a18b9e1f5; the latest probepark review is commentary at fa194dd08a880af0a3a4db2fbce2ec26c8c330c6.

Known limits, out of scope here: the failed row is captured at mark time, not request time, so a subagent sharing credentialSessionId can move the pointer during a retry backoff; a sticky index that dangles after an earlier row is removed still marks by pointer (existing index-keyed pointer maintenance).

Risk classification

  • low-risk — ordinary fix/maintenance; the repository owner may use the explicit merge-self-approved solo verdict (no independent human review; the verdict name itself records this) with a risk-record comment bound to the exact head.
  • regression-risk — fix with material regression risk; requires one assigned independent domain reviewer whose authenticated exact-head APPROVED review the gate verifies (extra:independent:<login>; the token alone never suffices).
  • high-risk — large refactor, feature, or materially high-risk change (security/auth/install/remove/public API/destructive lifecycle/architecture); requires one assigned independent domain reviewer with an authenticated exact-head APPROVED review (extra:independent:<login>).

Verdict

CHANGES_REQUESTED

Summary

This PR captures the failed credential row ID before session re-resolution so a Codex usage_limit_reached backoff targets the row that actually failed. The normal sticky-pointer drift scenario is addressed, but the new identity path converts that ID to a mutable array index across an asynchronous usage lookup, allowing concurrent credential inventory mutation to misattribute the backoff. In addition, the exact-head affected-test CI path did not run because the branch does not contain the required current dev base.

Findings / Required Changes

  1. [P1] Re-resolve the failed row after the asynchronous usage lookup — packages/ai/src/auth-storage.ts:4595-4618

    • This PR introduces a rowId contract to target the failed stored credential rather than the current sticky pointer, but it resolves that durable ID to an array index before awaiting #getUsageReport() and later blocks the saved index.
    • A concurrent shared-store update that removes or reorders a row preceding the failed row during that await shifts the array. When the await resumes, the code backs off the healthy row now at that index while the failed row remains eligible. Credential snapshots can replace/reorder rows through #setStoredCredentials, so this is a reachable failure of the new row-identity guarantee rather than the base behavior.
    • Preserve the row ID across the await, find its current index immediately before marking and computing the remaining pool, and return false if it no longer exists. Add a deferred-usage regression that removes or reorders a preceding credential while the lookup is pending.
  2. [P1] Restore exact-head CI eligibility for the regression proof — packages/coding-agent/test/credential-rotation-midturn.e2e.test.ts:192-204

    • The reviewed head 444a096007d63836384fc45d1fd622a086086c6f is missing required base 411b7f3809cec3949edeb6a60a767495c5639a96. Dev CI run 34209889710 failed at Affected path validation / plan (Verify PR head contains exact base) before affected-test planning, so the new regression tests were skipped.
    • Rebase onto the current required dev base and provide a green exact-head affected-validation run that executes the credential regression coverage.

CI / Verification

The added unit test covers explicit row-ID selection, legacy pointer behavior, and an unknown ID. The new E2E test covers first-request and post-tool quota failures, including the cache-already-exhausted case, and observes rotation/replay. However, Dev CI run 34209889710 failed before affected-test selection because this exact head does not contain the required dev base; the affected execution matrix was skipped. State-gate and native-addon checks succeeded but do not demonstrate the new behavior.

Axis Coverage

Axis Verdict Coverage
A1 — Intent / Policy / Contract CHANGES_REQUESTED Finding 1 violates the PR's explicit durable-row attribution contract.
A2 — Architecture / Correctness / Failure CHANGES_REQUESTED Finding 1 is reachable across the usage-fetch await and concurrent inventory mutation.
A3 — Security / Privacy / Trust APPROVED The opaque in-process row ID does not cross a new trust boundary; existing pin and owner/config guards remain.
A4 — Verification / Tests / CI CHANGES_REQUESTED Finding 2: exact-head affected-test CI was skipped after the required-base failure.
A5 — Context / Compatibility / Platform APPROVED The optional API preserves callers that omit rowId; gateway and remote/broker credential-ID paths remain compatible.

Limitations

The review was based on immutable commits d2f30f5c2d198e5dee6240428b5407f7d59ea989 (merge-base) and 444a096007d63836384fc45d1fd622a086086c6f (reviewed head). CI branch-protection required-context configuration was not available through the GitHub API, but the exact-head Actions run establishes that affected-test execution never began.

Thanks for the review. Both findings are addressed on the new head fb6736763.

1. Row re-located after the await — packages/ai/src/auth-storage.ts, markUsageLimitReached. The row id is now kept across #getUsageReport(); the index is re-located by id immediately before #markCredentialBlocked and before the remaining-pool count, and a row that vanished meanwhile marks nothing and returns false. The pointer path keeps its captured position, since the pointer is the only identity it has. Regression: test/auth-storage-mark-row-id.test.ts parks the failed row's usage lookup, removes a preceding row through removeAuthCredentialsHard while it is pending, and checks the named row is the one blocked (a session preferring it lands on the other survivor). It fails when the captured index is reused (Expected "api-acct-b", Received "api-acct-c").

2. Exact-head base — rebased onto the current dev (411b7f380); the head now contains the required base, so the affected-test plan should run.

Verification on the new head: the 14 credential/rotation test files across packages/ai and packages/coding-agent pass (88 tests), check:types passes in both packages, biome is clean.

One more commit on top, 6a6745490: the same re-location now covers the pointer path (no rowId). I had left it on its captured index on the reasoning that the pointer was the only identity it had, which was wrong — #setStoredCredentials calls #resetProviderAssignments on any identity or order change, so after a mid-await removal the pointer is already gone and the captured index named a bystander. Both paths now locate the target again right before marking; a cleared pointer marks nothing and returns false. providerKey is derived from the re-located target. Regression added for the pointer path (parked lookup, preceding row removed, nothing blocked; fails on the old index with Expected false, Received true). Head 6a6745490 still contains 411b7f380; 89 tests across the 14 credential/rotation files pass, check:types and biome clean in both packages.

I reviewed the full dev...196bffd6e30c410f924435240090685a18b9e1f5 diff, the markUsageLimitReached callers and consumers, the prior requested changes, and the credential-inventory mutation windows. The current head re-resolves both the explicit row-id target and the sticky-pointer target after the asynchronous usage lookup, so a removed or reordered preceding credential cannot redirect the backoff to a bystander. The quota path also captures the failed stored row before any re-resolution, marks that row, then verifies rotation by row identity.

The prior exact-head concerns are addressed. I found no blocking regression in the reviewed scope.

…t on a quota failure

`#markFailedCredential` resolved the session's credential before marking it.
That resolution re-runs the pre-request usage check, and once the cached
usage report already reads exhausted — the status-bar poll refreshes it on
its own clock — the check silently moves the session's sticky pointer to the
next healthy row. `markUsageLimitReached` then blocked the healthy row for
its default 60 s backoff, reported no remaining credential, and with default
settings the turn surfaced the raw `usage_limit_reached` error with no
replay while the row that actually failed stayed unmarked.

The quota branch now reads the row the session used, marks it first, and
names it: `markUsageLimitReached` gains an optional `rowId` that targets a
stored row directly instead of the sticky pointer, so nothing that resolves
in between can redirect the mark. Rotation is proven by stored row id rather
than key equality. When the pointer no longer resolves to a row (a row removed
earlier in the list shifts the index) the mark still goes first and falls back
to the pointer. The auth branch keeps its key-based proof.

Regression tests: test/credential-rotation-midturn.e2e.test.ts covers the
plain first-request failure, the failure right after a tool result, and the
cache-already-exhausted case that fails on the previous order (replay stays
on the exhausted account, then the error surfaces); it also pins that no
`retry.*` setting is configured, since a configured legacy retry would mask
the defect. test/auth-storage-mark-row-id.test.ts covers the new option in
both polarities and an unknown row id.
…imitReached

The rowId path resolved the id to an array index before awaiting the usage
report and then blocked that saved index. A credential snapshot that removes
or reorders a preceding row while the lookup is pending shifts the array, so
the backoff landed on whatever row now sat at the old index while the failed
row stayed eligible. The id is now kept across the await and re-located right
before marking and before the remaining-pool count; a row that vanished marks
nothing and reports false. The pointer path keeps its captured position, since
the pointer is the only identity it has.

Regression: test/auth-storage-mark-row-id.test.ts parks the failed row's usage
lookup, removes a preceding row meanwhile, and checks the named row is the one
blocked. It fails when the captured index is reused.
…well

The previous commit re-located only the rowId target after the await and
kept the pointer path on its captured index, reasoning that the pointer was
the only identity it had. That reasoning was wrong: #setStoredCredentials
calls #resetProviderAssignments on any identity or order change, which drops
the provider's session pointers, so after a mid-await removal the captured
index names whichever row now sits there and the mark blocked a bystander
while the failed row stayed eligible. Both paths now locate the target again
right before marking; a cleared pointer marks nothing and returns false.
providerKey is derived from the re-located target.

Regression: the pointer-path case in test/auth-storage-mark-row-id.test.ts
parks the failed row's lookup, removes a preceding row meanwhile, and checks
that nothing is blocked and the row at the old index stays usable. It fails
on the captured index (Expected false, Received true).
… before parking the pointer-path lookup

The pointer-path regression aged the cache by 6 minutes, but the usage-report
TTL carries +25% jitter and can reach 6.25 minutes, so on CI the mark's lookup
hit the still-valid cache, never reached the provider, and the test waited on a
handshake that could not fire until the runner's 5 s timeout. The cache is now
aged by 15 minutes, the handshake fails fast with a named reason instead of the
runner timeout, and releasing a lookup that was never parked is an error.
The helper indexed #getStoredCredentials twice, so the id lookup and the
type read could observe different snapshots when a concurrent update
replaced the provider's rows between the two calls. Reading the array
once keeps id and type on the same snapshot.

PR #5422 is verified locally but cannot be advanced to a terminal disposition from this session.

Identity remains base f19e6867547068d1c7eec237c68150c0fd69bcab and remote head e30df4a115e315317adee545241911b0761b102e. The canonical digest is 417dfc61139e37dd7c1c338c8801bca78e42c6362b04f9159605e86a939b1c48; the existing body binds that digest to this exact base/head and has exactly one regression-risk checkbox. The current contract failure is the intentional needs-human verdict, not a stale digest.

I rebased the fix-forward tree onto current origin/dev 8b2caa272b816997532e21d3636163efd76ffde9; the tested local candidate is 48be2bbd469155793ddac6ffcfc4fce9f6f71b93 (not pushed). Verification on that candidate: bun test across the 14 credential/rotation files — 87 passed, 0 failed; bun --cwd=packages/ai run check — passed; bun --cwd=packages/coding-agent run check — passed; bun run build:native — passed. The full bun run check reached the unrelated SDK-closure compiled-daemon smoke and failed because the binary build reaches markit-ai's require("mupdf") with a top-level-await transitive dependency; no PR file is involved.

The authorized push cannot complete: git push --force-with-lease to lifrary/gajae-code:fix/credential-mark-before-resolve is rejected with refusing to allow an OAuth App to create or update workflow .github/workflows/dev-ci.ymlwithoutworkflow scope. The authenticated GitHub identity has no direct push permission on the contributor fork, and server-side update-branch rebase/merge both return conflicts. The remote ref is unchanged at e30df4a115e315317adee545241911b0761b102e.

The only remaining owner action is to provide a GitHub credential with workflow scope for the authorized push, or have lifrary push the tested rebased candidate. The existing probepark approval is stale at 196bffd6e30c410f924435240090685a18b9e1f5, and snowykr's changes-requested review is stale at 444a096007d63836384fc45d1fd622a086086c6f; no qualifying exact-head approval exists.

Pushed the rebase myself, so the workflow scope blocker is cleared. New head bd705e796, rebased onto dev 08e05c83c; the PR now reports mergeable: true. The push went over SSH, which is not subject to the OAuth workflow-scope restriction that rejected the automated push — the rebase carries three dev commits touching .github/workflows/dev-ci.yml that my fork did not have yet, which is what tripped it.

The rebase was not mechanical. dev rewrote #markFailedCredential since this branch was cut: it gained a credential trigger class (from facts.credentialModelUnavailable) that also blocks a row through the session's sticky pointer, so it had the same defect this PR fixes. That class now takes the same marked-by-id path. It keeps its own getSessionCredentialType precondition, which like the row id is a synchronous read of the pointer and so cannot re-resolve between the read and the mark, and it keeps the default backoff rather than the response's retry-after, exactly as before. The one behavioral change beyond the fix: the pre-resolve that dev ran for every class now runs only in the auth branch, which is the branch that needs the active key. A session whose pointer was never established therefore returns unchanged instead of resolving-then-marking, which is the same contract the quota path already had.

The CHANGELOG entries were re-applied on top of the current Unreleased sections, and the coding-agent entry now names all three marking classes.

Extending the fix to the credential class is a judgment call, and it is the part of this head no reviewer has seen before, so please adjudicate it rather than reading the whole push as a rebase. For it: that branch has the identical defect three lines away, and leaving it would let a sibling branch violate invariant 4 that this PR's own docblock states. Against it: it widens a regression-risk diff past the scope that was reviewed, and dropping the pre-resolve means a session whose sticky pointer was never established now returns unchanged instead of resolving and then marking. If you would rather have the minimal rebase, say so and I will drop that one commit and leave credential on the sticky-pointer path exactly as dev has it.

Verification on bd705e796:

  • 43 credential / rotation / auth-storage test files across packages/ai and packages/coding-agent: 449 pass, 2 fail.
  • The two failures are auth-storage-grok-selection.test.ts's hybrid quota ranking cases, and they are pre-existing rather than mine. The same 41 files at clean dev 08e05c83c fail exactly those two (441 pass, 2 fail), and the file passes on its own in both trees, so it is batch-order pollution in that suite.
  • The six suites reaching the credential trigger class or getSessionCredentialRowId (agent-session-codex-model-selection, acp-builtins, account-inventory-usage, auth-gateway-pi-native, fallback-transport-auth-kind, openai-codex-stream): 206 pass, 0 fail.
  • bun --cwd=packages/ai run check and bun --cwd=packages/coding-agent run check both pass, so biome and tsc --noEmit are clean.

The body's verdict digest and maintenance snapshot are rebound to base 08e05c83c / head bd705e796. The verdict stays needs-human: this is regression-risk, and both existing reviews are stale at earlier heads (probepark's approval at 196bffd6e, snowykr's changes-requested at 444a09600), so an exact-head independent approval is still required. @probepark, would you re-review at bd705e796? I cannot re-request the review through GitHub myself, since a contributor lacks that permission on this repository.

Resolve-before-mark could move the sticky row and penalize a healthy credential. Capture the mark target once, re-find it after usage awaits, and require two known different rows before claiming rotation. This does not create dispatch-bound attribution.

Backlog follow-up prepared a current-dev narrow mark-order candidate with43 tests/266 assertions, ai/coding-agent types/Biome and independent scoped review CLEAR. It captures the initial row across usage awaits, marks before resolving, and requires two known different IDs for rotation; it explicitly does not claim dispatch-bound attribution.

Before publication, the live head changed from e30df4a to bd705e7. No push was attempted. The current contributor head is being reconciled read-only so no concurrent changes are overwritten or silently discarded.

Current-head reconciliation found a substantive addition in bd705e: mark-before-resolve now also covers the OAuth-only credential trigger with default backoff. That obligation is being preserved and tested, not discarded by the earlier local candidate. The local improvements additionally stabilize omitted-row targeting across usage awaits and reject unknown-before as proof of rotation. No push/force update performed; fresh combined trigger coverage and ancestry reconciliation are required.

Incorporate the contributor update from bd705e7 without losing stable mark-time targeting or known-row rotation proof. Preserve OAuth-only eligibility and default backoff rather than response retryAfter.

Lore-id: 5422oauth20260910
Confidence: high

Reversibility: easy
Tested: 49 tests, 347 assertions, types, Biome
Not-tested: dispatch-bound attribution
Retain contributor bd705e7 as an ancestor with the exact reviewed b105541 candidate tree. The candidate incorporates OAuth account-model rejection mark-before-resolve, its OAuth-only guard and default backoff without response retry-after. Preserve stronger stable mark-time row targeting and two-known-ID rotation proof instead of the older pointer reread and unknown-to-known inference. Auth handling and pin protections remain intact; no dispatch-bound attribution is claimed.

Constraint: exactly six candidate-version resolutions, no other tree changes
Scope-risk: narrow
Tested: staged tree equality dbac182
Not-tested: no tests or gates run for ancestry-only integration

Pre-review notes (head fa194dd, auto-generated — not a verdict)

CI: PR-cause 1 + base-origin 1 — Two failures:

  • "PR contract bootstrap" + "Validate exact-head PR contract": the verdict line in the PR body carries digest 1cd7ba255... (stale, from before the final rebase); the exact digest for head fa194dd is c115989f.... Gate rejects the stale digest. Author must update the verdict line in the PR body.
  • "Virtual integration validation": canary sdk-broker-restart.test.ts fails with ENOENT broker.lock/owner.json in broker.ts:2380. That file is not in this PR's diff — this is a pre-existing base failure. Dev CI run 34433019335 also hits sdk-broker canary failures (branch fix/issue-3350-risk-canaries-virtual-integration listed in affected-path logs, indicating dev is already broken there).

범위: +424 / -43, 6 files — packages/ai/src/auth-storage.ts, packages/coding-agent/src/session/agent-session.ts, two new test files (auth-storage-mark-row-id.test.ts, credential-rotation-midturn.e2e.test.ts), both CHANGELOGs

규약: CHANGELOG 있음 (packages/ai and packages/coding-agent both updated), generated 파일 없음, 라벨 없음, merge-self-approved 없음. PR body marks regression-risk with extra:independent reviewer required.

주목할 곳:

  • packages/ai/src/auth-storage.ts:4617–4625 — After the usage-report await, the target row is re-located from a fresh #getStoredCredentials snapshot. Correct. But the remainingCredentials filter at the bottom (lines ~4618–4625) calls #getCredentialsForProvider, which may return a third snapshot. In the window between the first re-find and the remaining-check, another row could be removed, making remainingCredentials inconsistent with the targetIndex used above. Practical impact is low (the mark already committed), but two distinct calls to the credential list after one await create a theoretical torn-read in the return value. Worth reviewer awareness.
  • packages/coding-agent/src/session/agent-session.ts:21596–21610 — When before is undefined (no session credential row id captured, unknown-before scenario), the code skips rotation and returns remaining ? "unchanged" : "exhausted" without calling getApiKey. The e2e test's unknown-before scenario covers this: it expects keys.length === failOn (no replay, no TOKEN-b). This is intentional and documented in the PR body. Confirmed by test.

blocking 후보: 없음 (CI failures are PR-author's stale digest + pre-existing base breakage; code review found no blocking defects)

verdict 초안 (digest c115989fa1e7, 리뷰어가 확인 후 복붙):

Reviewed the final exact head ed7b363006da94eee40bc77d77c86e2ddf0d770e against current dev 54e8cc3f8c517b0afe71eb0cccbabcb2872197d9.

The six-file change preserves the contributor's mark-before-resolve behavior across quota, rate-limit, and OAuth account-model credential triggers. The stored row is captured before awaited usage lookup, re-located by stable row ID after the await, and rotation is reported only for two known distinct row IDs. Pinned credentials and forbidden auth remain guarded. Focused row-ID/mid-turn tests, trigger coverage, AI/coding-agent checks, and native build passed locally; exact-head CI has passed the affected credential tests and is still completing the broader Dev CI run.

No blocking code finding remains on this exact head. This approval is intentionally bound to ed7b363006da94eee40bc77d77c86e2ddf0d770e and is invalid for any later push.

Reviewed exact head b48a7ff65526a90e08f199e6fb400d4d97d1398b against current base 1e8221fcf788a7beffe3d598bdc3d99087dda7bd.

The current-dev merge preserves the six-file credential-rotation change. AuthStorage captures a stable row ID before awaited usage lookup and re-finds it before marking; session recovery marks before re-resolution and only reports rotation for two known distinct IDs across quota, rate-limit, and OAuth account-model triggers. Pinned credentials, forbidden auth, OAuth-only guards, default backoff, row deletion/reordering, and stale usage-report cases are covered by the implementation and focused tests. Local focused tests and both package checks passed; affected exact-head credential shards passed on CI.

No blocking code finding remains. This approval is bound only to b48a7ff65526a90e08f199e6fb400d4d97d1398b.

A failed credential can be followed by a blocked fallback when no usable row remains. Treat the mark operation result as the availability proof and stop before re-resolving when every row is blocked.

Lore-id: pr5422-all-blocked

Constraint: replay requires an unblocked replacement row

Rejected: row-ID difference alone | all-blocked fallback can select a blocked row

Confidence: high

Scope-risk: regression

Reversibility: straightforward

Directive: keep mark-time row identity and default backoff behavior

The P1 all-blocked fallback finding is fixed. markUsageLimitReached remains the availability proof; when it returns false, AgentSession#markFailedCredential returns exhausted before resolving any blocked fallback. Replay now requires an unblocked replacement plus two known distinct stored row IDs. The stable row-ID mark-before-await fix, quota/rate-limit/OAuth credential trigger behavior, OAuth-only/default-backoff guard, pin guard, forbidden-auth guard, and row removal/reordering handling remain intact. Added all-blocked coverage passes for quota, rate-limit, and OAuth account-model triggers. Local changed suites pass 26 tests; focused trigger coverage passes 93 tests; AI and coding-agent checks pass; current exact-head affected CI credential/type/build shards pass while virtual integration is still queued.

No blocking code finding remains. This approval is bound only to 5f45011171155f5c8ad4ba7e9ee9f8a6897c4d6.

Reviewed final exact head fa12a000fa8e23cbcf2638ea1717ad875b7cf338 against current base fbc56ec5cec026620c444cd6080881af3cf9b349.

The all-blocked P1 safeguard remains correct after the latest current-dev merge: markUsageLimitReached returning false now stops recovery before any blocked fallback resolution, while valid rotation still requires an unblocked replacement and two known distinct stored row IDs. The stable row-ID mark-before-await logic, quota/rate-limit/OAuth trigger coverage, pin/forbidden guards, default backoff, and row reorder/removal handling are preserved. Final local suites pass 26 changed credential tests and 93 focused trigger tests; AI and coding-agent checks pass. Exact-head affected validation passed after a transient unrelated terminal-abort test timeout was rerun successfully; virtual integration passed.

No blocking code finding remains. This approval is bound only to fa12a000fa8e23cbcf2638ea1717ad875b7cf338.
