An entry stored subject_id, assurance and evidence_ref but nothing about
what kind of principal bound the approval, and subject_id is a naming
convention rather than a verified claim. /entries is not restricted by
principal type — only /consume is — and the approval-engine-operator
client holds approval:approve, so a service can supply approver evidence
today. Whether it may is gate-house doctrine; that it is legible is ours.
Add entries.principal_type, populate it from the verified token, surface
it on the object and the audit evidence path (not the claim, which stays
least-disclosure), and migrate v3 stores leaving legacy rows null rather
than back-filling a claim nobody made.
Also corrects two statements in the requirements issued to
informed-decision: agent tokens are not barred from approval:approve, and
an empty assurance object is accepted rather than refused.

Gate House ruled binding.pdp_digest is the binding correspondence on the
GH-DEC-2026-003 path and is required there, having rejected a vocabulary
mapping for the reasons we gave. It asked this engine to record the PDP
digest at issue for approvals intended for that path, and to have the
claim state which approvals those are rather than leaving it to the
requester's memory.
Schema v3 adds approvals.pdp_path. create() refuses pdp_path true without
a pdp_digest, so an approval that would be unusable on the path fails at
issue rather than at the protected side effect. The claim exposes
binding.pdp_path, which makes it a guarantee rather than a hint: pdp_path
true implies pdp_digest is non-null.
Intent is declared and never inferred. A pdp_digest that happens to be
present is not a declaration anybody made, so a recorded digest alone
leaves pdp_path false, legacy rows migrate to false rather than being
back-filled from their digests, and a successor inherits its
predecessor's declaration. Approvals issued before the ruling stay usable
by consumers in this engine's own vocabulary and are simply not usable on
the PDP path -- the ruling's intended cost, stated as such.
Schema, both published examples, a v2-to-v3 migration test asserting
survivors keep their digest while declaring no path intent, and tests for
refusal at issue, claim exposure, non-inference, and successor
inheritance. 102 tests pass (8 new).

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.
