+
+- A unification flush now commits the finalization, actionable prompts, and one
+  deterministic `UNIFICATION_WAIT` suspension together. A late archive failure
+  rolls the whole boundary back; retry creates one ledger.
+- The suspended command queue admits only an invader decision tied to the
+  active ledger. The daemon-authorized command transaction applies a 36-hour
+  exact gap, preserves participant positions, changes the fixture rate from 10
+  to 20 minutes, creates one invader nation and ten deterministic generals with
+  future first turns, and writes one final-rate projection outbox.
+- The dedicated PostgreSQL/Redis fixture reached `RUNNING@2/2` only after the
+  Redis projection. DB-wall versus a mocked 12-hour host drift and concurrent
+  general-access lock acquisition completed without drift or deadlock.
