Senior second pair of eyes on an agreed PR/repo slice — fixed scope, not an open-ended audit.

Deliverables: • Review of the locked slice (agreed at kickoff) • Written review pack: verdict + findings tagged block / should / nit • Hours-band note and clear out-of-scope list

Not included: implementing fixes, merge rights, whole-monorepo audit without a slice lock.

Kickoff: repo access + which PRs/paths to cover. Async AWST.
