"""ORCH-094 — the real deploy cycle is NOT suppressed by the guard (TC-11 / AC-4).

A genuinely-deploying (non-terminal) self-hosting task must still walk
`Awaiting Deploy -> Deploying -> Monitoring after Deploy -> Done` exactly as before
ORCH-094. The critical regression case is the LEGITIMATE first `Monitoring`: by the
time the terminal-sync runs the task is ALREADY DB-`done` (update_task_stage ran
above), so the guard would wrongly converge it to Done UNLESS the arm-block moved
ABOVE the terminal-sync (ADR-001 D3) marks the post-deploy window active first.
This test exercises that ordering end-to-end via run_deploy_finalizer with the REAL
guard + REAL arm_monitor wired in (only the network PATCH primitive is mocked).
