Phase 2 attached mitre_url to intel-emitted tags' evidence JSON;
Phase 3 promotes it to a real column populated for *every* tag —
intel, credential, behavioral, canary, identity, email, rule-engine —
from one source. Pre-v1, so the SQLModel field is added directly
without an Alembic migration.
- TTPTag gains mitre_url: Optional[str] (not indexed — derived
deeplink, not a query target; technique_id is already indexed).
- _emit.py and rule_engine._evaluate_rules both populate mitre_url
via attack_stix.mitre_url_for(sub_technique_id or technique_id).
Sub-technique URL when present, else parent. The two construction
sites stay separate because the rule_engine path carries per-emit
span instrumentation that emit_tags() can't preserve without
threading a span object through; minimal-change beats forced
refactor here.
- intel_lifter strips mitre_url from evidence_extra in all four
decision functions. The column is canonical now; duplicating in
the JSON column would drift when the bundle moves. The unused
TechniqueEmission import + tracking dicts removed too.
- IdentityTechniqueRow / TechniqueRollupRow / TTPTagDetailRow /
CampaignTechniqueRow gain mitre_url: Optional[str].
- sqlmodel_repo/ttp.py:_mitre_url_for added; the 5 row-builder sites
pass mitre_url=_mitre_url_for(sub_technique_id or technique_id)
alongside the existing technique_name resolution.
- api_get_tag_details.py needs no change — list_tags_by_scope_and
_technique already returns model_dump() rows that flow the new
column through **row spread to TTPTagDetailRow.
- tests/ttp/test_emit_attaches_mitre_url.py covers both construction
paths (top-level, sub-tech, unknown, multi-emit) and a regression
test that intel_lifter evidence dicts no longer contain mitre_url.
Reads pre-shaped session aggregates from TaggerEvent.payload and emits
techniques per Appendix A behavior tables. Per-rule predicates dispatch
on match.kind (lifter:behavioral_<name>); the lifter holds its own
RuleIndex watching the same RuleStore as the engine, so disable / clip /
TTL state reaches lifter-bound rules through the same atomic-swap path.
R0032/R0036/R0037/R0040 YAMLs had over-escaped regex strings (\\
instead of \\) — fixed in place.
Factory wired so default get_tagger() returns CompositeTagger with
BehavioralLifter shipped; remaining three lifters (E.3.10-E.3.12) land
in subsequent commits.
E.2.6 contract preserved via TolerantTagger: empty payload steady-state
yields [] with zero ERROR records. Disabled / clipped / expired state
verified.
