# `[2026-09-19]` The ops log is BUILT — `scripts/ops-log`, automatic writers, and a detector for the path they cannot cover.

⭐⭐⭐ **The ops log is BUILT — `scripts/ops-log`, automatic writers, and a detector for the path they cannot cover.** Central on nh3-dev because both agents are the same unix user there (journald was the tempting alternative and would have split the log silently along the `infra-ops`/`lkraven` axis). Claim is `mkdir`-atomic, held across the whole diff→prompt→apply window, auto-breaks stale AND logs the break. `deploy-stack.sh` refuses a foreign claim (exit 3); ops-log being broken never blocks a deploy. 136-stack baseline laid so the detector starts from today. ⚠ Caught my own instrument saying "clean" for an unreachable host — now INCOMPLETE/exit 5. See in-flight § BUILT for the four settled design questions and the known hole (actors outside nh3-dev).
