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.
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.
