approval-engine owns the approval object: durable, authenticated entries,
atomic supersession, single consumption, revocation without holder
cooperation. It is an Engine; access-engine remains the only decision point
and consumes approvals as input claims.
Origin: the unowned half of the approval contract, raised by flex-auth in
FLEX-DEC-2026-001 while assenting to the security layer model. Not gate-house
(Staff holds no runtime state), not access-engine (an evaluator that owns what
it evaluates is self-dealing), not audit-core (append-only, wrong property).
The seed README described this as "modelling and managing decisions" —
withdrawn. Under the standard, "decision" is access-engine's word.
