GH-DEC-2026-005 moved the distinct-approver check off the PEP onto this
engine's valid_now. secrets-engine has implemented the split and reports
it no longer verifies the threshold independently. Gate House accepted
that as correct on layering AND as a genuine reduction in defence in
depth, and named the compensating control: not a second check at the PEP,
which is the duplication the split removes, but reconstructability at the
issuer under §9.6.
The emitted events could not support that. approval.issuance carried
required_count but never who satisfied it, and approval.use carried no
threshold evidence at all, so an auditor replaying the stream could not
recompute the evaluation without reading live rows -- rows that may since
have been superseded, revoked, or expired.
Both events now carry a threshold object: required_count,
distinct_approver_count, threshold_met, and approvers with approved_at
plus assurance and evidence_ref when recorded. Tests prove reconstruction
from the use row alone, and that the claim still discloses no approver
identities -- they are evidence for audit-core, not consumer-facing, and
the claim keeps disclosing the least it can.
Writing the tests showed distinctness is already a storage invariant:
entries is UNIQUE on (approval_id, subject_id), so a repeat approver is
refused at insert and a separate entry_count could never differ from the
distinct count. Dropped that field rather than ship a number that cannot
vary, and the test now asserts the refusal instead.
88 tests pass (4 new).

Gate House confirmed all three requested dispositions as GH-DEC-2026-005
(GH-IN-0002, closed); flex-auth accepted as FLEX-DEC-2026-006. The
approval-claim is the step-1 artifact, ActionAuthorization is not
required and MUST NOT be served from the claim endpoint, and a PEP
validates across the claim and the step-2 DecisionEnvelope. Gate House
recorded the split as doctrine rather than convenience -- a PIP must not
republish the PDP's decision -- and struck the provenance.authority ==
state-hub requirement explicitly. This engine's claim schema is
unchanged.
Correct the deferred option D trigger list. The G3 trigger was written
conditional on G3 being settled by composition; flex-auth reports
FLEX-WP-0019 closed it by adding a lifetime field to DecisionEnvelope on
2026-09-02, so a decision now states its own end without borrowing
ActionAuthorizationValidity. That was the one structural thing the bundle
did that the split does not, so the trigger is not merely spent -- it
resolved against ratification. Struck with reasons; a future revisit
needs a fresh argument. The trigger came from a stale row in a dated
2026-08-29 review record that flex-auth does not rewrite.
Also record the root cause of the bad authority constant: it came from a
flex-auth fixture, not prose. A contract whose examples contradict its
prose will be implemented as its examples.
Close APPROVAL-IN-0002. Docs only; 84 tests pass.

secrets-engine reports its PIP join is implemented and blocked on
deployment rather than contract. Reviewing its
validate_action_authorization against what this engine actually serves
shows that is not the whole story: it expects a state-hub-authority
ActionAuthorization (id, status, superseded_by, request,
approvals.entries, policy pin) while GET /v1/approvals/{id}/claim serves
the governed approval-claim (approval_id, state/valid_now, binding,
freshness, reason_code, issuer approval-engine).
Both envelopes declare schema_version 0.1, so the version check passes
and the mismatch surfaces as a field or authority error that reads like
an approval-engine outage.
Document the field-by-field divergence and why the omissions are
deliberate: a claim is a fact about an approval object, not a decision,
so approver identities and policy pins are not republished. Reconciling
the envelopes is a GH-DEC-2026-003 cross-repo change, so the governed
claim schema is left unchanged here.
No code change; 84 tests still pass.

Close remaining in-repo APPROVAL-WP-0002 gaps: drive GH-DEC-2026-003 against
the real HTTP surface, fail closed on JWT/human-consume/static-token paths,
treat audit 200 duplicates as drained, and ask KeyCape for the production
audience and client grants.
