The IntelLifter's _emit_filtered fans out only the rule.emits entries
whose technique_id appears in the predicate's decision set. v1's emits
lists were narrow supersets of the common case, silently dropping the
rest of the predicate's possible emissions:
R0054 dropped: T1046 (cat 14), T1078 (cat 20), T1090 (cats 9/13),
T1496 (cat 11), T1595 (cats 14/19)
R0055 dropped: T1090 (tor_exit_node), T1110 (ssh_bruteforcer),
T1588 (the second emit of every C2-framework tag)
R0057 dropped: T1105 (payload_delivery, download_url)
Bump rule_version 1->2 on R0054/R0055/R0057, expand emits to cover
every technique the predicate produces. R0056 (Feodo) and R0058
(aggregate bump) carry no enum and stay at v1.
All five YAMLs gain `last_reviewed: "2026-05-02"` and
`next_review: "2026-08-02"` markers; the rule YAML is now the
canonical record of when the mapping was last reconciled against
upstream, with DEBT.md as the calendar reminder.
5 YAMLs for the intel-verdict cohort per Appendix B / A.10:
AbuseIPDB category mapping, GreyNoise classification, Feodo
Tracker hit, ThreatFox IOC type, aggregate-malicious bump-only.
IntelLifter (E.3.10) consumes by rule_id and tolerates absence
silently (null provider column → no tag).
R0058 is the meta bump-only rule — emits a single confidence=0.0
sentinel so it validates and surfaces in the catalogue, but the
repository's sub-0.3 drop ensures no fresh tag persists if the
fanout fires accidentally. test_intel_rules.py pins that
zero-confidence invariant.
Marks E.3.8 done in development/TTP_TAGGING.md with the cohort-
split summary.
