tegwick a0a602976e Principal is the requesting party, not the approver
informed-decision asked whether its binding.principal and ours name the same
field, since both GH rulings said its slice canonicalizes "two of the five".
They do not: ours is the party on whose behalf the act is performed, taken from
the decision request's subject, while theirs is the approver — which appears
here only as an entry and never in binding. Only target overlaps.

Records the four-role distinction normatively in docs/approval-claim.md and
guards it with a test asserting the act digest is insensitive to the approver
while the approver stays recorded on the entry. Folding approver identity into
the digest would now break view_hash's assumption here rather than silently in
that repository.

approval-engine

The approval as a durable, authenticated, consumable object — issued before an action, verified at the moment of use, and provably not replayable.

An Engine, role PIP, in the NetKingdom security layer model (statute v0.7, accepted; operative form net-kingdom/SECURITY-COMPANION.md). It answers one question, totally and decidably:

Is this approval valid right now — for this exact action, target, actor, and purpose — and has it already been used?

It does not decide whether the action is permitted. That is access-engine, which stays NetKingdom's only policy decision point. An approval is one input to that decision.

Deliberately small, boring, and strict: atomic supersession and single consumption are what make Canon test T-06 — Approval Replay passable. Flexibility here would be a defect. Graded, evidence-based progression belongs to maturity-engine; the two engines are deliberate opposites.

See INTENT.md and SCOPE.md. Declaration: layer.yaml. Claim: docs/approval-claim.md. Consume: docs/approval-consumption.md. Caller auth: docs/caller-authentication.md. PEP sequence: docs/pep-integration.md. Origin: flex-auth FLEX-DEC-2026-001, raised while assenting to the security layer model.

POST /v1/approvals/{id}/consume implements GH-DEC-2026-003: the PEP atomically spends the approval before the protected side effect. Same-digest retries are idempotent; a different digest conflicts.

Production operations, caller scopes, audit delivery, and PEP sequencing are documented in docs/storage-operations.md, docs/caller-authentication.md, docs/outbox-contract.md, and docs/pep-integration.md. The checked-in StatefulSet deliberately refuses production startup without a migrated persistent store, KeyCape JWT verification, and authenticated audit delivery.
