tegwick df48ee96e0 feat: assert flex-auth ceiling keys are declared, not assumed
flex-auth fixed enrichment so registry facts beat caller-supplied ones
(FLEX-DEC-2026-012) and asked each consumer to confirm the ceiling and
allowlist keys are actually declared -- the fix wins only where the registry
HAS a value, and a manifest omitting max_ttl_hours hands that ceiling back
to the caller.

Confirmed, and made durable rather than read once.
scripts/check_flex_auth_manifest_coverage.py audits both ways a ceiling
gets handed back: an actor with no manifest resource at all (warden sign
names ssh-cert:actor/<name> whether or not the snapshot was rebuilt --
an honour-system step in SCOPE.md), and a resource missing one of the
seven keys. A null is treated as absent, because for enrichment it is.

Also asserts the property their exploitability assessment rested on and
nothing here held: ops-warden sends no resource.attributes. It was true
when they read it, secrets-engine sends them on every request, and it was
one refactor from silently stopping being true.

Current state: no gap. 4 actors, 4 resources, all seven keys declared.
