fix(ci): restore the AI auditor by upgrading the firewall/api-proxy - #263
Conversation
The auditor has failed every run since 2026-08-10 (green for the 16 runs before that), aborting on `unknown_model_ai_credits` for `gemini-3.1-flash-tts-preview` with 0 tokens consumed — a red check that meant nothing had been reviewed. That error is raised inside the api-proxy, whose pricing table ships in the firewall image. Recompiling with gh-aw v0.83.4 moves it 0.27.0 -> 0.27.42. Pinning the model alone does not work: the proxy resolves the model independently of the request, so `gemini-2.5-flash` and `gemini-2.5-pro` both still landed on the TTS model. Verified green on run 31648687169: 28,434 tokens, agent/detection/safe_outputs all success. `actions/checkout` (v7.0.1) and `actions/setup-node` (v7.0.0) are held at the SHAs on master, which a plain recompile reverts to v6. `gh-aw-actions/setup` moves to v0.83.4 to match the compiler; its pinned SHA e89c65e was checked against the annotated tag.

How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughThe AI auditor workflow was upgraded to gh-aw v0.83.4 and Gemini 2.5 Pro. It now uses rootless AWF execution, daily AI-credit tracking, OAuth validation, an MCP-based Safe Outputs container, expanded usage artifacts, and updated detection handling. ChangesAI auditor workflow upgrade
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The workflow can drop pending auditor runs during bursts, which may leave changes unaudited even after the auditor is restored. Merge should wait until queued-run preservation is configured and the generated workflow is updated. Sequence Diagram(s)sequenceDiagram

Every security check passes — the gate does not fail on note — so these do not block. But they are a real cost, and the call is yours, so I am not burying it in the diff:
- Accept: two
notefindings in generated code, in exchange for a security reviewer that actually runs. It has reviewed nothing since 2026-08-10 — nine runs attotal_tokens: 0while showing a red check that read as coverage. - Alternative:
engine: copilot, which is 4/4 green on two other workflows here and avoids the v0.83.4 compiler entirely — at the cost of the deliberate free-tier choice recorded in the workflow comment.
I did not hand-patch the generated lock to silence them: the next gh aw compile would revert it, which is precisely the failure mode this PR guards against with the actions/checkout pins.
End-to-end verification
The auditor ran on this PR via a real pull_request event and passed — not just the manual dispatches. That also retracts a guess I made on #262: I speculated GitHub declines to auto-run a workflow whose own file the PR modifies. #263 modifies the same file and got its automatic run, so that hypothesis is wrong; #262's missing run remains unexplained.

…ot be raced The compiler's default concurrency group is keyed by PR number, so audits of different pull requests land in different groups and run concurrently. Each one reads the shared daily AI-credit counter before any has written its own consumption, so the budget is overshot by however many started together — opening several PRs at once, a Dependabot batch for instance, is enough. Sets one shared group for the whole repository via the frontmatter `concurrency` key, which gh-aw supports and which the schedule-driven workflows (daily-secrets-analysis, duplicate-code-detector) already get by default. `cancel-in-progress: false` costs nothing here: the trigger is `pull_request: [opened]`, not `synchronize`, so pushing further commits to a PR does not re-fire this workflow and there is no superseded run worth cancelling. Recompiled with the pinned v0.83.4 already on this branch. All eight action SHA pins verified byte-identical, so no Dependabot update was reverted.

Sharing one concurrency group in a5edd12 fixed the credit-counter race but introduced a worse failure: `queue` defaults to `single`, which keeps one pending run and replaces any older pending one. A burst of pull requests would collapse to one running plus one waiting, and every other PR would be dropped without ever being audited — trading an overspend for silently missing reviews. `queue: max` keeps up to 100 pending runs in FIFO order. Past 100 they are still dropped, which is an acceptable bound: reaching it needs 100 pull requests opened inside a single audit's runtime. All eight action SHA pins verified byte-identical across the recompile.
gh-aw v0.83.4 deprecated `engine.model` in favour of a top-level `model`, and every compile emitted a warning per workflow file. Ran `gh aw fix ai-auditor --write` and recompiled; the compile is now clean at 0 warnings. `gh aw fix` also wanted to scaffold `.github/agents/agentic-workflows.md` and `.github/skills/agentic-workflows/`. Those are a separate gh-aw feature rather than part of this deprecation, so they were dropped — worth adopting on purpose, not as a side effect of a migration. All eight action SHA pins verified byte-identical, and the concurrency block from #263 (shared group, queue: max) is preserved.

Every failing run aborted on
unknown_model_ai_creditsforgemini-3.1-flash-tts-preview— a text-to-speech model with no entry in the AI-credits pricing table,exit 144,total_tokens: 0. It was failing identically on #259, #260 and #261, so this is one bug, not three. A red check that means "nothing was examined" is worse than no check, because it reads as coverage.Two plausible fixes that CI disproved
model: gemini-2.5-flashmodel: gemini-2.5-pro0.27.0→0.27.42gemini-2.5-proAttempt 2 is the informative one: a
prorequest still landed on aflash-ttsmodel, which means the proxy chooses independently of what is requested. No workflow-file setting could have fixed it.unknown_model_ai_creditsis raised inside the api-proxy, and its pricing table ships in the firewall image. The alias globs are byte-identical between compiler v0.79.4 and v0.83.4 (gemini-3.1*flash*is present in both), so configuration was never the variable — the image was. Recompiling with gh-aw v0.83.4 moves the image to 0.27.42.Verified green: run 31648687169 —
agent,detection,safe_outputsall success. The error string still appears once in that run, then it recovers and completes, so the pin and the image bump both contribute: the newer proxy retries instead of dying, and the pin gives it a valid target.What to check in review
The lock is ~455 lines of regenerated output. Two things in it are worth a human eye:
actions/checkoutstays at v7.0.1 (3d3c42e) andactions/setup-nodeat v7.0.0 (8207627). A plain recompile reverts them to v6.0.3 / v6.4.0, because Dependabot bumps theuses:lines while the lock's embedded manifest still records v6. Verified 0 remaining v6 references. Master moved checkout v7.0.0 → v7.0.1 mid-work, and this branch carries the newer one.gh-aw-actions/setupmoves v0.79.4 → v0.83.4 — required, since the setup action must match the compiler. Its new pine89c65ewas verified against the annotated tag:refs/tags/v0.83.4→ tag objectc9e4f32→ commite89c65e, matchingactions-lock.jsonexactly.Dropped from #262
That PR also added six files to
.secretsignore.masteralready contains all six (plus more), so it is now redundant and is not part of this branch.No changeset: CI/tooling only, no package behaviour change.
