tegwick 3c2cdcdf79 AUDIT-WP-0010 T01/T03/T04 — admit tenant-engine, and the envelope does not match
Registration: attributive, with the declared completeness_trade recorded on the
receiver side rather than only in the emitter, per §9.6's requirement that the
trade travel with the trail. tenants ["*"] is justified rather than inherited —
tenant-engine's events carry the affected tenant, the set is every tenant
including ones created later, and an explicit list would fail closed at exactly
the moment a tenant is provisioned, dead-lettering the creation evidence of the
tenant whose creation it is. source stays pinned exactly. Ingress ANDs namespace
and pod label; a weaker evidence class is not a reason for a wider network rule.
All inert until the token exists.

Then the finding T04 existed to find: tenant-engine cannot deliver a single
event today. envelope_for sends five required fields under other names —
event_id, action, resource, observed_at, details — and omits correlation_id
entirely, so normalize() raises invalid_event. Verified by running the real
envelope through the real function, not by reading.

Worse than an ordinary integration bug. The drain treats 400 as terminal, so the
outbox row is marked handled while audit-core holds only a dead letter, which is
not chained and is not custody. Lost on both sides, and since the drain is
non-blocking and attributive, nothing fails loudly — a silent total loss of the
stream presenting as a working integration.

Taking the correction the intake invited rather than accepting a lossy record.
normalize() is NOT relaxed to accept the alternate spellings: a receiver that
guesses which sender key means which stored field has made the mapping its own,
and the record stops being the sender's assertion. correlation_id cannot be
synthesized at all — an invented one ties an event to an operation audit-core
never observed.

Root cause is ours. The accepted envelope was published nowhere a sender could
read it; audit-backend-contract.md describes the stored record, and a sender
reading it would reasonably infer exactly the names tenant-engine used.
schema_version audit-core.event.v1alpha1 selects nothing here and gave a false
impression of a negotiated contract. Published docs/event-envelope.md as the
wire contract, including the point that a 400 means the event is not in the
archive and must be treated as a defect to fix rather than a delivery outcome.

T05 moved to wait: nothing to prove end to end until an event can be accepted.

Reliable multi-tenant auto setup audit capability

Production on railiance01 (AUDIT-WP-0005): PostgreSQL custody, digest-pinned image, operator procedures in docs/operator-runbook.md. Manifests live in deploy/.

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.
