+Native durable registry/message/progress/interaction mutations now atomically
+store verified authorization attribution, their existing ledger row and an
+immutable committed-outcome envelope. Added migration `0006_outcome_outbox`,
+retry/backoff delivery with stable receiver idempotency keys, lifecycle-owned
+dispatch and protected backlog readiness. Rollback creates no outcome; a lost
+receipt can replay after restart. Downgrade refuses undelivered rows.

+Local SQLite tests and real Audit Core receiver-source checks cover this slice;
+production PostgreSQL lock scheduling, grants, receiver admission and retention
+remain open. Compatibility/embedded/external writes and background projection
+refreshes are not claimed as covered. T03/T04 remain `progress`.
+Validation: **366 tests passed**, including the opt-in Audit Core owner-source
+suite. Inventory drift, distribution builds, isolated installed-wheel checks
+and current migration/context/store wheel contents pass.
+No database migration or deployment was applied to a live service.
