10 YAMLs for the behavioral / cross-event cohort per Appendix B: beaconing, data destruction, ransom note, web exfil, DB mass-read, credentials-in-files, k8s SA token harvest, Docker host escape, LLMNR poisoning, TFTP router-config retrieval. Every rule is lifter-bound (BehavioralLifter / IdentityLifter) — the v0 RuleEngine cannot count, aggregate, or compose cross-event signals, so these YAMLs declare the technique mappings the lifter will consume by rule_id at E.3.9. Their match specs use a 'kind: lifter:*' shape inert to the regex matcher. test_behavioral_rules.py asserts each YAML compiles, none fire from the v0 engine (FP regression guard against a YAML drifting into a regex), and an xfail(strict=True, reason='impl phase E.3.9') precision case that will flip green when the lifter lands.
