+
+## Scope
+
+This repository owns durable audit records, audit administration surfaces, retention behavior, and the transactional platform-event outbox.
+
+## Documentation Contract
+
+- Treat documentation as part of every behavior change. Update this module's manifest-driven `DocumentationTopic` contributions for affected user and administrator behavior.
+- Keep feature content here; `govoplan-docs` projects it without importing Audit internals.
+- Maintain a static user/admin baseline and run `/mnt/DATA/git/govoplan/tools/checks/check-manifest-shapes.py` after behavior or manifest changes.
+
+## Boundaries
+
+- Store bounded evidence and trace context, not arbitrary feature payloads.
+- Preserve transactional recording, retention, redaction, and retry guarantees.

 `govoplan_audit.backend.outbox.SqlAuditOutbox` persists platform events in
-`audit_outbox_events`. Dispatchers can later call
-`dispatch_pending_platform_events()` to publish pending events and record retry
-state. The outbox payload stores the full governed event envelope:
+`audit_outbox_events` and one durable state row per allowlisted consumer in
+`audit_outbox_deliveries`. Dispatchers supply stable consumer IDs and
+idempotent handlers. Consumer work and its delivered marker share one database
+transaction; retries reuse the stable `<event-id>:<consumer-id>` delivery key.
+Bounded failures are quarantined instead of retried forever. The outbox payload
+stores the full governed event envelope:
 correlation/causation ids, actor, tenant, subject, resource, classification,
 module id, event id, type, and payload.
 
+Public and internal events may use an allowlisted subscription directly.
+Confidential and restricted subscriptions additionally require a persisted
+policy-decision reference. Operators can inspect delivery metrics at
+`GET /api/v1/admin/audit/event-delivery/metrics` and replay a retrying or
+quarantined delivery with a reason through
+`POST /api/v1/admin/audit/event-deliveries/{event_id}/{consumer_id}/replay`.
+Replay itself is written to the audit log. Successful envelopes are subject to
+configured retention; quarantined evidence is not removed automatically.
+
 Application code should enqueue or publish facts only after the state change
 they describe is known. Long-running operators and installers should model
 requested work as commands first, then emit facts as events as each step

+# Audit Interface Pattern Migration
+
+Audit contributes two read-only administration surfaces through the shared
+`admin.sections` capability. Both use the platform's monitoring and evidence
+archetype.
+
+## Surface Map
+
+| Surface | Authority | Pattern | Consequence class |
+| --- | --- | --- | --- |
+| `audit.admin.system` | `system:audit:read` | Server-filtered evidence grid and event inspector | Read-only evidence disclosure |
+| `audit.admin.tenant` | `audit:read` for the active tenant | Server-filtered evidence grid and event inspector | Read-only evidence disclosure |
+
+Audit does not expose mutation or destructive actions in these panels. The
+only row action opens an inspection dialog; reload preserves the stable shell
+and existing evidence while a newer projection is requested.
+
+## Interaction Contract
+
+- Core owns the admin layout, DataGrid, dialog, action group, loading/error
+  treatment, disabled-action explanation, and documentation link.
+- Filtering, sorting, counts, and paging are server-owned. The first page may
+  apply bounded delta updates using an opaque watermark; a full response
+  remains authoritative when the delta contract cannot be used.
+- System and tenant panels remain distinct and are registered only with their
+  respective read scopes. Tenant selection is never accepted as a free-form
+  client override.
+- The event inspector renders stable actor, action, object, tenant, timestamp,
+  and structured detail rows. It does not add editing, replay, export, or raw
+  credential access.
+- Contextual help resolves through `audit.read-authorized-evidence`; operational
+  recording, retention, and outbox guidance remains in the separate admin
+  topic.
+
+## Verification
+
+Run the Audit backend suite and `npm run test:interface-patterns` in `webui`.
+The structural test guards shared components, localized labels, contextual
+help, server paging, readable detail projection, and absence of private sibling
+imports or browser-native dialogs.
