GOAL.md still carried the first-draft invariant — "nothing this repo builds sits
synchronously in a decision path" — after flex-auth's review had rejected it as
a latency guarantee wearing an authority guarantee's clothes. Under that wording
zone-engine could compile enforced: false for a lane, flip warden sign from deny
to allow with no flex-auth policy change, and be literally compliant. Replaced:
identity and membership here, effect in a flex-auth policy package. Compiled-not-
queried is demoted to a consequence of that, which is what it always was.
SCOPE now records what the two reviews settled rather than what was proposed:
separate standard (canon Decision 5.6), membership declared in tenancy.yaml's
reserved zones: key, stance out of scope for controls flex-auth decides, the
fail-open axis modelled PEP-side because a PDP structurally cannot express it,
organization_posture an input rather than a declaration field, and reefs not
ours. Plus the two inherited constraints: the dead trust_zone field already
sitting where membership would go, and flex-auth's lack of a reload path.
INTENT.md states the argument, including what would falsify the repo — the
exception lifecycle not needing a runtime is called out as a legitimate outcome
that should archive this repo rather than keep it for its own sake.
