IdentityLifter owns lifter:identity_* — currently R0003 (password spraying). CredentialLifter owns lifter:credential_* — R0001 generic auth brute, R0002 password guessing, R0004 credential reuse, R0005 valid-account use, R0006 default credentials. YAMLs R0001/R0002/R0003/R0005/R0006 had their match.kind normalised to fit the lifter prefix scheme — the design doc's promised "YAMLs normalised in a separate refactor commit" lands here. Identity-rollup tags null out attacker_uuid on emit so the worked- example invariant holds (the tag belongs to the Identity, never to one member IP). Tests: test_identity_lifter.py + test_credential_lifter.py cover each predicate's positive/negative path, state modulation (disabled/clipped/expired), source-kind gating, and idempotent replay. test_lifter_absence and test_lifters updated for the new ctor signature.
