For the rules-engine agent

Pack target was 50–100 rules for full 16 Delaware coverage (multi-family, change-of-use, NEC electrical, NFPA 54 gas, JC zoning/parking, IECC energy). Each rule needs: a capability + rubric_version + active_version row, plus an entry in this pack's capability_slugs_json. Predicates are author-served code with a SHA-256 fingerprint so the audit trail proves nothing silently drifted.
