fix(ci): stop AI PR Review from failing a successful review - #17
Conversation
The review comment and pass label are posted before the approval call, so a dead AI_REVIEW_APPROVER_TOKEN was turning a completed review into a red check. Degrade to "reviewed, not approved" and surface the HTTP code in the step summary instead of raising.

There was a problem hiding this comment.
When GitHub's approval request reaches the 30-second timeout, urllib.request.urlopen can raise TimeoutError, which is not a subclass of urllib.error.URLError. In that transient network scenario, the exception still escapes after the comment and label were posted, leaving the successful review as a failed workflow—the behavior this change is intended to prevent. Catch TimeoutError alongside URLError, as the Anthropic request path already does.

AI PR Review has failed 26 times across 4 repos in the last 72h while the review itself succeeded every time. Two independent causes, both in the wrap-up after the review is already posted:
ai_pr_review.py): the auto-approve POST returns401 Unauthorized(AI_REVIEW_APPROVER_TOKENexpired or under-scoped) and raises, after the review comment and pass label have already landed. Now caught: the run degrades to "reviewed, not approved" and prints the HTTP code and likely cause in the step summary.ai-pr-review-v2.yml):--max-turns 15is below what a real review costs —gh pr diff+ per-file reads + one inline comment per finding. ObservedClaude reported a successful result after 18 turnsanderror_max_turns(nostructured_output) on a 3-file PR. Raised to 40; spend is bounded by the daily USD cap, not by this number.Applied identically across all 16 repos carrying these workflows (v1 script sha was
d7a86c89everywhere, v2 workflow sha4f88ddb9everywhere).Note: the 401 itself is a separate follow-up — the approver PAT still needs rotating for auto-approve to resume.
