  "description": "Static GENERIC meta-schema that ANY concrete policy profile must satisfy for anu_v3.policy_profile_engine to load it. Intentionally a superset contract: requires only the engine-universal identity fields (profile_id, version) and recognizes engine-relevant blocks; additionalProperties:true so profile-specific blocks (e.g. test_only_hardening_pr_merge_v1's merge_ready_predicate / gemini_thread_resolve / scope_invariants) validate unchanged. Existing single profile semantics preserved (§8).",
