v1.36.185

T-0165/T-0166/T-0167/T-0171/T-0172: adds honest provider-capacity observation, exact-file TTL leases, strict Role/Agent/Routing v2 schemas, a fail-closed legacy role-store loader, and availability-aware role fallback with revision-bound execution provenance. Compatibility fields remain explicit, high-risk reviewer independence requires concrete model identities, corrupt state is preserved without provider execution, and all new surfaces are covered by adversarial regression probes.
