# 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
|
|
|
|
```task
|
|
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
|
|
|
|
```task
|
|
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
|
|
|
|
```task
|
|
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
|
|
|
|
```task
|
|
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.
