A pre-deploy review found the receiver is not deployable as built. The
ingestion path never calls AuditBackend.emit(), so a 202 means a SQLite row
exists, not that a backend with a declared retention policy accepted the
event. Storage exceptions escape the handler with start_response never
called. Tenant isolation and source binding are recorded as done but are not
implemented. There is no read, replay, or correlation-lookup surface, so the
failure matrix cannot produce the evidence NK-WP-0024 needs.
WP-0003 closes as finished on its narrowed scope (contract + reference
implementation, T01/T02). T03 and T04 are cancelled with rationale.
WP-0004 covers receiver correctness and hardening, storage-agnostic so it
runs in parallel with the database platform work.
WP-0005 covers the Postgres backend, deployment, SQLite record migration,
and the live failure matrix. Production storage moves from SQLite-on-a-volume
to the Railiance PostgreSQL platform (RAPP-POSTGRES-WP-0002).
