+**Deferred from C5 (flagged, slot in as more saga phases — no engine change):**
+- **provision** phase — needs the shared-Postgres **host-port coupling** (pgx
+  connects from the host; default is no published ports). Decision is known
+  (ledger-allocated published port wired into generate + the saga); it's the next
+  M2 follow-up. Until then projects use the shared engine's root creds.
+- **clone** (gitx), **secrets** (M4/S6), **trust** (N5), **firstRun** hooks
+  (need the provisioned-volume scope_key) — each adds one phase.
+- **Saga daemon e2e in CI** — needs **G1**'s isolation harness (parameterized
+  `devstack-it-<pid>` network/prefix; the saga must never touch a real
+  `devstack_shared`). Unit wiring is mock-tested; e2e was verified manually.

 - (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.
+- (night 2 cont.) **C5a, C5b, C6, C7, C8 merged** (PRs #8–12) — **M2-remainder complete**. The resumable/compensating orchestrate engine + the real up phases, the `up`/`down`/`status` CLI, and `shared gc`/`doctor --rebuild-state`. Verified the whole `up` saga end-to-end against the host daemon (shared-postgres came up *healthy* via the cross-project gate; re-run all-skips; `--json` matched; `down` dropped refs) then fully tore it down — the machine was clean before and after. Process note: poll ALL ≥9 PR checks to green before merge (an early poll once merged C6 before the slow checks registered — it passed retroactively, but the lesson stuck). **Next ready (all parallel now C5 is in): the provision saga phase (host-port coupling), S1 secrets core, N1–N4 networking, X1 config completion, X8 self-update notifier, X9 migrate/import, G1 integration lane.**
