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".
Additive Phase 1 of BEHAVE-INTEGRATION.md. Lays the storage layer
the BEHAVE-SHELL extractor (DEBT-050) will write into. Nothing
breaks; SessionProfile coexists for now and is dropped in the
follow-up commit.
decnet/web/db/models/observations.py — new ObservationRow SQLModel
mirroring the BEHAVE Observation envelope field-for-field
(core/decnet_behave_core/spec/envelope.py). ``id`` is a hex-string
UUID (matching BEHAVE), not a typed UUID column. ``identity_ref``
is str | None — written by the future attribution engine, NULL
until then. ``attacker_uuid`` is the one DECNET-side
denormalisation; FK'd to attackers.uuid for cheap AttackerDetail
joins. ``evidence_ref`` is NOT NULL for DECNET emissions even
though the upstream envelope makes it optional — the worker's
"already profiled?" check keys on it. UniqueConstraint(evidence_ref,
primitive) enforces idempotency at the schema level so re-running
the extractor on the same shard+sid produces a DB-side conflict
the upsert path resolves deterministically. Class is named
``ObservationRow`` (not ``Observation``) to avoid colliding with
the BEHAVE Pydantic envelope at sites that import both.
decnet/web/db/sqlmodel_repo/observations.py — ObservationsMixin.
Three public methods backing the canonical queries from
BEHAVE-INTEGRATION.md §"Storage": ``upsert_observation`` (idempotent
on the natural key), ``latest_observation_per_primitive`` (per-
primitive MAX(ts) subquery, portable across SQLite and MySQL — no
DISTINCT ON), ``observations_time_series`` (asc-by-ts). Plus
``has_observations_for_evidence`` for the worker's session-already-
profiled check.
decnet/bus/topics.py — ATTACKER_OBSERVATION_PREFIX = "observation"
constant + ``attacker_observation(primitive)`` builder. Full topic
shape ``attacker.observation.<primitive>`` matches what BEHAVE's
spec.event_adapter.event_topic_for produces upstream. Documentation
+ pattern matching only — bus auth is socket file perms (DEBT-029
§2), not topic-level.
decnet/web/db/repository.py — abstract ``upsert_observation``,
``latest_observation_per_primitive``, ``observations_time_series``
on BaseRepository.
tests/db/test_observations.py — 11 tests covering upsert round-trip,
idempotency under the unique constraint, latest-per-primitive
ordering across multiple sessions, time-series asc-ordering, empty-
attacker contract, every BEHAVE ValueKind round-tripping through
the JSON column, and the has_observations_for_evidence check.
tests/db/test_base_repo.py — DummyRepo gains the three new abstract
overrides so its coverage suite still instantiates.
New MalHashProvider sibling ABC (decnet/intel/base.py) since SHA-256
is a different keyspace from IntelProvider's IPs. MalwareBazaarProvider
mirrors FeodoProvider's bulk-feed shape: 24h refresh via _ensure_fresh
/ _refresh, in-memory set[str] of hex-lowercased hashes, set-membership
lookup. Auth-keyed via DECNET_MALWAREBAZAAR_AUTH_KEY; absent key
silent-no-ops the lane (single warning, no HTTP traffic).
Per-hash observations persist to a new observed_attachments table.
DECNET is a honeypot platform — every attachment hash an attacker
delivers is intel, regardless of whether anyone classified it. Verdict
is sticky: True never downgrades to False/None on subsequent
observations. Out of scope: API surface, federation export, retention.
Ingester _publish_email_received calls the provider for each attachment
sha256, sets mal_hash_match on the bus payload (omitted entirely when
the message had no attachments — keeps R0046's `is True` predicate
silent on hash-less mail, matching pre-paydown behavior), and upserts
the row regardless of provider availability.
Empty NotImplementedError bodies; the SQL lands at E.3 implementation.
Mixin composed onto SQLModelRepository alongside the existing domain
mixins. Dialect-specific INSERT-OR-IGNORE syntax overrides land in
the per-backend subclasses at E.3 per the dual-DB-backend convention.
