Implement the engine spine: claim, outbox, machine, API
Contracts first (T02–T04): approval claim schema with issuer, freshness,
and binding digest; local transactional outbox wire; load-bearing cadence
as heartbeat or reconciliation (layer.yaml declared).
Then the object (T06–T08): SQLite closed state machine, CAS supersession,
distinct-approver fail-closed, revocation without holder cooperation,
outbox insert in the same transaction. Tests fail the mutation when
emission fails, and revoke while the drain sink is down.
Introspection GET /v1/approvals/{id}/claim is a PIP fact, not a decision.
No public consume (T05 waits on GH-WP-0002-T06). Canon T-06 coverage for
wrong binding, expiry, revoke, and supersede.
FLEX-WP-0017 T03 is unblocked on this object; T05 remains blocked only on
consumption ordering.

State pdp_digest explicitly; decline to publish a vocabulary mapping
flex-auth asked whether this engine should publish an action/target
mapping between the claim binding's vocabulary (secrets.kv.destroy,
{"id": "lane-openbao-root"}) and a policy package's (destroy, lane:...),
since their package makes no cross-check that a claim was approved for
the action being decided.
Answered no. A PIP asserting that one vocabulary's action means
another's would author policy semantics it does not own, over
vocabularies it does not own, and the failure mode is asymmetric: a wrong
mapping silently accepts a claim approved for a different action, which
is worse than no mapping. binding.pdp_digest is the correspondence and
sidesteps vocabulary entirely -- it compares the PDP's own digest to the
PDP's own digest, with no translation by anyone.
Implemented the part that was ours. pdp_digest was emitted only when
recorded, so a consumer could not distinguish "not issued against a
decision" from "we forgot to look". It is now always present and null in
that case, required-but-nullable in the schema, and documented as
something a PEP on a privileged lane must refuse. This engine states the
fact; enforcing the lane's policy stays with the consumer.
Both published examples were already contradicting the updated schema by
omitting the field -- the same fixture-versus-contract defect flex-auth
hit twice this week and that secrets-engine implemented. Fixed both, made
them cover the PDP-bound and unbound shapes so neither is inferred from
the other, and added tests/test_examples.py to validate every example
against the schema so the class cannot recur here. jsonschema added as a
dev dependency.
94 tests pass (6 new).
