Why

Engine Review Pass (.github/workflows/engine-review-pass.yml) takes the author engine from the branch prefix and checks it against ALLOWED_ENGINES. antigravity is missing, so Antigravity's PRs #3626, #3627 and #3628 (antigravity/... branches) fail with:

Invalid author engine. Please use an engine branch prefix such as gemini/ or claude/.

Their valid cross-engine PASS markers can never count until the prefix is allowed.

Change

One line: add 'antigravity' to ALLOWED_ENGINES, same format as the existing entries. No other change.

Verification

• actionlint .github/workflows/engine-review-pass.yml passes.
• After merge, re-run Engine Review Pass on fix(nlp): ReDoS guard in query planner (code-scanning #8, #9) #3626 to fix(admin): strict browser nonce cookie format (code-scanning #58) #3628.

Note

Low Risk
Single allowlist entry in CI workflow only; no application or security logic changes.

Overview
Engine Review Pass now treats antigravity as a valid engine name, alongside existing entries like claude and gemini.

PRs on branches prefixed with antigravity/ were failing the workflow’s author-engine check before any cross-engine REVIEW: PASS markers could count. That prefix is now allowed in ALLOWED_ENGINES, so Antigravity-authored PRs can pass the check when another engine posts a valid PASS for the current head SHA.

Codex review of 5a1b53c. One-line add of antigravity to ALLOWED_ENGINES in engine-review-pass.yml.

• Format: correct. It is lowercase and has no separators. The author engine is the lowercased branch prefix before /, and the reviewer engine is matched by [A-Za-z0-9._-]+ and lowercased before the Set lookup. #3626, #3627 and #3628 use antigravity/... branches, so they now pass the author check.
• Self-PASS: a marker whose engine equals the branch-prefix engine does not count, so REVIEW: PASS antigravity on an antigravity/ branch is ignored. Note that the file itself says all engines post through one shared account, so this is an audit trail, not a cryptographic gate. That is unchanged by this PR.
• #3637 (still OPEN, unmerged) deletes engine-review-pass.yml and carries its own ALLOWED_ENGINES copy in pr-guards.yml (around L1212), which does NOT include antigravity. Whichever lands second must carry it: if #3646 lands first, #3637 needs antigravity added to pr-guards.yml when it rebases, or the regression returns silently.
• actionlint: clean.

REVIEW: PASS codex 5a1b53c
