 ## Night log
 - (init) scaffolding: PROGRESS.md + Apache-2.0 LICENSE/NOTICE + nightly cron + repo auto-merge enabled.
 - (night 1) **C1 merged** (PR #1, `9900b87`) — `saga_phase` v2 migration + CRUD, race-clean, merge-on-green proven. Next ready (parallel): C2, C3a, S1, N1..N4, X1, X8, X9, G1.
+- (night 2) **C2, C3a, C3b, C3c, C4 merged** (PRs #2–6) — the entire health/hooks substrate: read-only docker inspect/logs, config health/hooks/dependsOn structs, the `internal/health` poller, generate's compose `healthcheck:`/`depends_on` lowering, and the `internal/hooks` runner + `hook_run` ledger. Each green via `make ci`+determinism+`-tags=integration` against the local Engine 29.5.3; PR-poll-then-merge enforces the green gate (main is unprotected, so plain `--auto` would merge instantly). **C5 (core saga) is now unblocked** — its deps C1,C2,C3b,C4 are all in. Also ready: C8, S1, N1..N4, X1, X8, X9, G1.
