Destructive half of BEHAVE-INTEGRATION.md Phase 1. SessionProfile +
its kd_* columns + the dialect ALTER TABLE migration helpers are
deleted outright; pre-v1, the table shipped empty, no migration
ceremony required (per the no-new-_migrate_-pre-v1 memory rule).
DEBT-036 closes via DEBT-050 supersedure. AttackerDetail's
``observations`` field is wired to the new ``observations`` table
and returns an empty list until the BEHAVE-SHELL extractor (DEBT-050
Phase 2) starts emitting.
decnet/web/db/models/attackers.py — SessionProfile class deleted
(~135 lines), KD_PAUSE_*/KD_START_OF_ACTION_IDLE_S module constants
deleted, module docstring updated to point at the observations
table. AttackerIdentity.kd_digraph_simhash is KEPT — it's the v2
federation centroid hook, not a SessionProfile field; docstring
repointed to the BEHAVE primitive that will populate it.
decnet/web/db/sqlmodel_repo/attackers/sessions.py — DELETED.
SessionProfilesMixin dropped from the AttackersMixin MRO.
decnet/web/db/repository.py — abstract upsert_session_profile +
get_session_profile removed.
decnet/web/db/sqlite/repository.py + mysql/repository.py —
_migrate_session_profile_table helpers and their initialize() calls
removed. mysql initialize() now goes attackers → column_types →
admin (no session_profile step).
decnet/web/db/models/__init__.py — SessionProfile re-export gone.
decnet/web/db/models/attacker_intel.py — docstring cross-reference
to SessionProfile.schema_version retargeted to AttackerIdentity.
decnet/web/router/attackers/api_get_attacker_detail.py — adds
``observations: []`` to the response by calling
``repo.latest_observation_per_primitive(uuid)`` and projecting to a
list sorted by primitive path. Empty until the extractor lands;
shape matches BEHAVE-INTEGRATION.md §"AttackerDetail consumer".
tests/profiler/test_session_profile.py — DELETED (56 lines).
tests/db/test_base_repo.py — DummyRepo loses upsert_session_profile
and get_session_profile overrides.
tests/db/mysql/test_mysql_migration.py — initialize-call-order
assertion updated; session_profile step removed from the expected
sequence; docstring records why.
tests/ttp/test_lifter_absence.py — docstring "no SessionProfile" →
"no ObservationRow".
The collector's `attacker.session.ended` envelope carries
`attacker_uuid: null` and `attacker_ip: <ip>` because the collector
doesn't talk to the DB. The TTP worker passed that null straight
through, and `TTPTag.__init__` raised the documented invariant:
ValueError: ttp_tag requires at least one of attacker_uuid /
identity_uuid; both NULL is not a valid anchor.
The worker now resolves `attacker_uuid` from `attacker_ip` via
`BaseRepository.get_attacker_uuid_by_ip` before fanning out the
event. When the IP isn't in the DB yet (profiler hasn't ingested
the row), the event is dropped with one log line — better than
exploding mid-tag.
- New `get_attacker_uuid_by_ip(ip) -> str | None` on the repo
(BaseRepository abstract + AttackersCoreMixin impl).
- `_resolve_attacker_uuid` helper in `decnet/ttp/worker.py` runs
before `_build_events`. Short-circuits when the payload already
has either anchor; drops the event when neither anchor is
resolvable.
- Tests pin: short-circuit on existing uuid/identity, repo lookup,
drop on unknown IP, drop on "Unknown" sentinel, drop on
no-anchor payload, drop on repo failure.
- Add _MixinBase abstract class to _helpers.py: declares _session(),
_deserialize_attacker(), _assert_pending(), _check_and_bump_version(),
and list_running_topology_deckies() so mypy can see cross-mixin contracts
- Add _require(val, msg) helper for narrowing T | None → T
- Inherit _MixinBase in all 26 leaf mixin classes
- Wrap SQLAlchemy column method calls (.is_(), .like(), .notin_(), .in_(),
.contains()) with col() from sqlmodel — fixes attr-defined false positives
caused by pydantic plugin typing class-level fields as Python value types
- Wrap select(Model.field) with select(col(Model.field)) for column projections
- Add pyproject.toml [[tool.mypy.overrides]] to disable arg-type in
sqlmodel_repo.*: pydantic plugin resolves .where(Model.field == v) as
where(bool), a false positive; call-arg still catches real argument errors
- Remove 9 stale # type: ignore comments (logging, helpers, credentials)
- Fix telemetry.py traced() overload no-redef + misc
- Fix logs.py datetime/str operator and nullable PK comparison with col()
- sqlmodel_repo/ now has 0 mypy errors
