AUDIT-WP-0003 - user-engine event ingestion service

Provide the authenticated, durable cluster event receiver for user-engine's transactional outbox. Reuse audit-core's intended POST /v1/events boundary; do not turn user-engine into an audit-retention service.

T01 - Finalize the ingestion contract

id: AUDIT-WP-0003-T01
status: done
priority: high
state_hub_task_id: "620a6910-60d6-4ef0-b82b-37eacb2fcf1d"

Map the user-engine envelope fields (id, type, source, subject, tenant, correlation_id, occurred_at, data) into the normalized audit-core event schema. Define validation, redaction, size limits, tenant isolation, Idempotency-Key behavior, and stable HTTP error semantics.

Done when valid events preserve correlation and duplicate event IDs are accepted idempotently without duplicate custody records.

Done 2026-08-09: the normalized contract preserves event, tenant, correlation, occurrence, source, subject, type, and redacted data; request size, timestamp, source, secret-shaped fields, and Idempotency-Key are validated.

T02 - Implement authenticated durable ingestion

id: AUDIT-WP-0003-T02
status: done
priority: high
state_hub_task_id: "a6fce44e-8977-47f0-8a75-9ce431cc27a6"

Implement POST /v1/events with scoped workload authentication, schema validation, idempotency storage, bounded request handling, and durable backend write acknowledgment. Reject missing/invalid credentials, cross-tenant claims, secret-shaped fields, oversized payloads, and malformed timestamps.

Done when a successful response means the event is durably accepted and retryable failures do not lose or duplicate evidence.

Done 2026-08-09: POST /v1/events requires a constant-time bearer check and stores normalized records plus payload hashes in SQLite. Exact duplicates return 200 without a second record; conflicting IDs and malformed events fail. All 15 repository tests pass.

T03 - Deploy the single-cluster receiver

id: AUDIT-WP-0003-T03
status: progress
priority: high
state_hub_task_id: "fc0b5850-1954-448c-8729-ffe93d7b530f"

Publish an immutable image and deploy audit-core API plus durable backend on railiance01. Provide Service discovery, health probes, resource/security controls, default-deny NetworkPolicy, backup/restore, retention, and rollback. Deliver the user-engine sender credential through the approved OpenBao lane.

Done when only the user-engine workload can use its sender identity and the receiver survives pod restart without losing idempotency state.

T04 - Prove delivery, retry, and replay

id: AUDIT-WP-0003-T04
status: todo
priority: high
state_hub_task_id: "8d1624de-3e71-41c9-80ac-ab522313a0da"

Exercise successful delivery, receiver timeout/unavailability, bounded user-engine retry, dead-letter visibility, operator replay, duplicate replay, redaction, and correlation lookup through the deployed path. Hand non-secret evidence back to NK-WP-0024.

Done when one source outbox event produces exactly one durable normalized event across retries and replay.
