+# Transaction-linked native operation outcomes
+
+HUB-WP-0012 source candidate, 2026-09-28. Live sender admission, database rollout
+and owner acceptance remain open.
+
+## Coverage and transaction boundary
+
+The durable native registry, message, progress-event and interaction-event writes
+already append to `runtime_audit_ledger` in their business transaction. Enforced
+requests now bind those ledger rows to the verified issuer/subject, actor/target
+tenant, principal type, policy decision/version/caller, request digest and
+server-generated authorization correlation ID. This context comes from the
+access boundary, never command payloads or caller-supplied correlation headers.
+It is scoped to handler execution and reset in `finally`.
+
+The same transaction inserts one immutable `hub.operation.committed` envelope
+into `runtime_outcome_outbox`, keyed by its ledger ID. Failure to insert either
+record rolls back the business mutation. A rolled-back transaction has no
+committed outcome; the earlier authorization receipt remains an authorization
+attempt. Registry duplicate acknowledgements have `registry.duplicate` operation
+records and do not pretend a new registration was created.
+
+The envelope contains business object references and a payload hash, not message
+bodies, event payloads, credentials or tokens. Business correlation IDs are
+retained separately from verified authorization correlation IDs. That verified
+ID and decision ID join the outcome to the pre-execution signed decision already
+held by Audit Core. The outcome does not duplicate the signed envelope.
+
+This slice covers the native durable mutation ledger. It does not claim outcome
+coverage for compatibility/embedded-host mutations, background projection refresh,
+external services, or in-memory development stores. Non-enforced maintenance
+writes retain their existing local ledger behavior without fabricating an actor
+or emitting an attributed remote outcome.
+
+## Delivery, recovery and readiness
+
+When a durable store and outcome-capable audit sink are composed, the runtime
+starts a dispatcher and cancels it before closing clients or stores. It selects
+up to 25 eligible rows per batch, one database transaction per row, and waits
+one second between batches. PostgreSQL uses `FOR UPDATE SKIP LOCKED` so workers
+can select different rows. Each receiver call is bounded to three seconds.
+
+`AuditCoreSink.append_outcome` reuses the operational-custody probe, rotating
+sender credential and exact accepted/duplicate receipt checks. All retries use
+the same event ID, occurrence timestamp and body; the ID is also the idempotency
+key. Only an accepted receipt marks the row delivered. Failed attempts retain
+the row with persisted exponential retry delay (one second up to sixty seconds).
+Exceptions are not stored as diagnostic text. Cancellation or a crash before the
+local delivery acknowledgement leaves the row eligible for replay. Delivery is
+at least once; receiver deduplication resolves a lost receipt or duplicate send.
+It does not change business mutation idempotency or make a client retry safe.
+
+The authorization audit still requires synchronous remote custody before the
+handler. Queuing a committed outcome does not weaken that check. An outcome
+outage after authorization cannot undo an already committed operation.
+
+Protected readiness adds `outcome_delivery`: missing delivery composition is
+`unavailable`, a pending row older than sixty seconds is `stale`, and a young or
+empty backlog is `ok`. Database readiness checks that the new table is accessible.
+Pending rows are never silently discarded. Delivered rows remain for inspection;
+retention/pruning needs a separately admitted operational policy.
+
+## Schema and rollout
+
+Migration `0006_outcome_outbox` adds the table, ledger foreign key and pending-row
+index. Apply it through the existing owner migration lane before deploying this
+candidate and admit runtime SELECT/INSERT/UPDATE privileges. Automatic downgrade
+requires an online check and refuses a nonempty pending queue. Drain pending
+outcomes and preserve required custody records before schema rollback.
+
+The Audit Core sender must admit `hub.operation.committed` for source `hub-core`
+and tenant `tenant:platform`, in addition to existing authorization record classes.
+This document neither issues that grant nor claims production delivery.
+
+## Local evidence
+
+Tests use SQLite-backed durable stores to prove atomic rollback, handler rejection,
+all native mutation families, actor/decision attribution, concurrent request
+isolation, persisted retry delay, reopen/replay, cancellation, stale-backlog
+readiness, dispatcher drain/shutdown and migration shape/downgrade refusal.
+The real Audit Core receiver/storage source accepts the eight-field envelope and
+returns a duplicate receipt on replay. Its operational-readiness classification
+is explicitly a test fixture; this is not live custody evidence.
+
+PostgreSQL multiworker lock scheduling, production grants, retention and deployed
+failure-detection/receiver acceptance still require integration receipts.
+
+Validation on 2026-09-28: 366 tests pass with the opt-in owner-source suite enabled;
+inventory drift, package build and isolated installed-wheel checks pass. The
+wheel includes the current migration, authority-context and durable-store code.
