Двусторонняя аудиторская проверка фичи в Maestro

★ 7.1 · general

maestro-witness is a Claude Code skill that conducts the final feature close gate in Maestro, running after proof and QA pass and before `maestro feature close`. It writes exactly two receipt sidecars — `witness.md` and `advisor.md` — auto-invokes an independent fresh-context advisor subagent, applies the risk-tier policy (T0–T3), and emits `Gate: APPROVED` only when both receipts are current, independent, and complete. The `witness.md` maps every accepted `ac-N` to proof and QA evidence with handoff, proof, QA, and git HEAD anchors; `advisor.md` requires a distinct session or subagent with verified independence. Teams use it when a confirmed, dual-party auditable close trail is required before shipping a feature.
