AUDIT-WP-0005-T02 (progress). rapp-postgres has landed platform-pg with the audit_core database, roles, and dynamic credential provisioning, so audit-core's side is now built against it. In-cluster delivery is a mounted directory rather than environment variables. A dynamic lease rotates while the pod runs and an env var is fixed at process start, so env delivery would force a restart on every rotation - and every restart is a delivery gap, which is what this task forbids. CredentialDirectory is re-read on every connection attempt via psycopg_pool's callable kwargs, so a rotated lease takes effect with no restart. Rotation is logged by password fingerprint, never by value. deploy/externalsecrets.yaml follows the ClusterSecretStore -> ExternalSecret -> Secret pattern already used by activity-core and rapp-qonto, at a 15m refresh rather than the default 1h since the interval bounds how long a revoked lease can stay mounted. All manifests validated --dry-run=server --validate=strict. The rotation test was initially vacuous: it passed against a deliberately naive implementation that read credentials once at startup, because pooled sessions stay authenticated after a password change and nothing forced a reconnect. It now terminates the role's sessions first, and is verified to fail against the naive implementation and pass against the real one. Tests 82 -> 84.

Reliable multi-tenant auto setup audit capability
Backend contract
The pluggable backend interface, event schema (audit-core.event.v1alpha1),
retention policy, and migration path from the mock file backend are documented
in docs/audit-backend-contract.md.
Development Mock Backend
The first implementation is intentionally tiny: a replaceable audit interface with a mock file backend.
By default it writes JSONL audit events to:
/tmp/audit-core/audit-YYYYMMDDTHH.jsonl
Files older than 7 days are removed when the backend writes or when cleanup is run explicitly. This backend is for local integration and bootstrap wiring. It is not durable audit custody.
Example:
python3 -m audit_core emit \
--source openbao \
--action openbao.authenticated_readiness_proof \
--resource openbao/openbao-0 \
--outcome success \
--detail file_audit_visible=true \
--detail backend=mock-file
Cleanup:
python3 -m audit_core cleanup
Make targets:
make test
make mock-audit-smoke
make mock-audit-cleanup
Environment:
AUDIT_CORE_MOCK_DIR: override the output directory.AUDIT_CORE_MOCK_RETENTION_DAYS: override the default 7-day cleanup window.
