The TTPsObservedSection rollup tells the operator "we saw T1059" but
not why. Click any technique row → side drawer opens listing every
ttp_tag row in scope with the persisted evidence JSON, firing
rule_id / rule_version, source_kind / source_id, confidence, and
created_at. Mirrors the CredentialReuseInspector / BountyInspector
pattern (drawer-backdrop + bd-head/bd-body + kvs grid).
Backend:
- New `GET /api/v1/ttp/tags/by-{scope}/{uuid}/{technique_id}`
(`scope ∈ {identity, attacker, session}`, optional
`?sub_technique_id=`, `?limit=` capped to 1000). Returns raw
TTPTag rows newest-first.
- New `TTPTagDetailRow` Pydantic model + re-export.
- New repo method `list_tags_by_scope_and_technique` on
TTPMixin (+ abstract on BaseRepository) — single query branched
on scope; identity scope projects through `Attacker.identity_id`
the same way `list_techniques_by_identity` does.
- Tests: evidence round-trips, sub_technique filter, JWT-required,
empty scope, unknown scope rejected.
Frontend:
- New `TTPInspector.tsx` + `TTPInspector.css` (violet accent, slide
animation, focus-trapped panel matching the existing inspector
family).
- `TTPsObservedSection`'s TechniqueBar is now click+keyboard
activatable; clicking opens the inspector for that
(technique, sub_technique) tuple.
mypy clean. 532 passed in the targeted sweep.
The endpoint was a contract-phase stub returning `[]` even though the
RuleStore loaded all 58 YAML rules at worker startup. UI saw an empty
table; operators couldn't tell whether anything was wired up.
- `api_list_rules` now calls `get_rule_store().load_compiled()` and
serializes each CompiledRule + its operational state into a
RuleCatalogueRow. Sorted by rule_id for stable golden snapshots.
- Add `description: str` to RuleSchema (pydantic) and CompiledRule
(NamedTuple, defaulted) + propagate through `_compile_one` so the
catalogue surfaces the human-readable YAML description, not just
the slug-style `name`.
- Update `tests/ttp/test_rule_engine.py` _fields assertion for the
new column; new `tests/api/ttp/test_rules_catalogue.py` pins the
catalogue contents (R0001/R0014 presence, row shape, sort order).
Worker behaviour is unchanged: it was already loading rules
correctly. This is purely a read-side wiring fix on the operator API.
Mounts /api/v1/ttp/* with empty-list / empty-Navigator responses.
GET endpoints viewer-gated; POST/DELETE /rules/{rule_id}/state
admin-gated server-side. POST parses JSON manually so a malformed
body returns the documented 400 (per feedback_schemathesis_400).
Drops xfail-strict markers from E.2.8 tests now that the router is
mounted; 26 tests pass against the contract handlers.
