Engine/PIP declaration is now checkable (layer.yaml plus a Tooling-client
scan). Writes persist a decision record or the published fail-closed
stance, live-lookup freshness is published, events_for is tenant-scoped,
and mutation evidence drains to audit-core from a local outbox without
blocking the mutation.
Sender registration is requested as AUDIT-IN-0002. Boundary-contract
amendment is requested as NET-IN-0002.

Add the PostgreSQL backend, migration and stopped-write transfer tools, lease-aware deployment manifests, tenancy declarations, and shared conformance coverage. Persist grouping mutations in durable stores and separate process liveness from database readiness.
flex_auth.py: CheckRequest + FlexAuthCheckClient against flex-auth's real
POST /v1/check contract (schemas/check_request.schema.json,
decision_envelope.schema.json, read directly from the flex-auth repo, not
guessed). Fail-closed by construction: only effect=="allow" authorizes;
every other effect, non-200, malformed body, or transport failure resolves
to deny, nothing raises past is_allowed().
authz.FlexAuthWriteAuthorizer implements the existing WriteAuthorizer
Protocol. Action -> resource-type mapping coordinated with FLEX-WP-0008's
planned vocabulary (both repos reference the same table).
DefaultDenyWriteAuthorizer stays the fallback when no flex-auth URL is
configured.
config.py: Settings.from_env(), mirroring qonto-assistant's pattern.
docs/flex-auth-integration.md documents the contract, fail-closed rule,
and current real state (denies everything until FLEX-WP-0008 lands).
60 tests passing. Verified live twice over real HTTP between separate
processes (not just MockTransport): a deny-returning flex-auth double
produces 403 from POST /tenants, an allow-returning one produces 201.
Also registered (not implemented) the two workplans this depends on for a
complete picture: flex-auth/FLEX-WP-0008 (protected-system registration --
what makes allow reachable) and key-cape/KEY-WP-0005 (discovered key-cape
emits none of iam-profile_v0.3.md's core claims yet, not just missing
tenant_roles -- a bigger, security-sensitive gap flagged rather than
quietly worked around).

Python 3.12 + FastAPI, pyproject.toml + Makefile mirroring
qonto-assistant's exactly. src/tenant_engine/{domain,store,app,main}.py:
- domain.py: Tenant, CapabilityRole (PLTF/IAM/VEN/CUS), RoleGrant,
PlanAssignment, create_role_grant() enforcing ADR-0014's invariants.
Refinement made while implementing: platform_default grants are valid
for trial-grouped tenants OR the reserved tenant:platform/tenant:coulomb
tenants (their baseline roles were never purchased either) -- the task
spec only named the trial case.
- store.py: TenantStore Protocol + InMemoryTenantStore, every mutation
emits a DomainEvent per the boundary contract's Audit Correlation
Contract.
- app.py/main.py: FastAPI factory + /health endpoint, verified live on
127.0.0.1:8090.
29 tests passing, including non-exclusive role coexistence (CUS+VEN
simultaneously) and append-only revoke semantics.
