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.
New GET /api/v1/orchestrator/events/stats?since=1h&success=false&kind=...
backed by repo.count_orchestrator_failures(since_ts, kind), which
counts failed rows across both orchestrator_events and
orchestrator_emails since the cutoff.
Window parser accepts ^\d+[smhd]$, capped at 7d. Today only
success=false is accepted on this surface so the endpoint isn't
accidentally repurposed before the next consumer is properly
designed.
Orchestrator.tsx polls the endpoint on mount + every 30 s and
renders the authoritative DB-derived count instead of deriving from
the in-memory SSE buffer + one paginated page (which silently
excluded failures older than the local window).
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 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.
The TTP worker entry moved out of decnet/cli/workers.py into its own
module so the TTP CLI surface (worker + admin verbs) is colocated,
mirroring decnet/cli/canary.py / webhook.py / swarm.py.
- New `decnet/cli/ttp.py` with `decnet ttp` (worker, ExecStart-stable
for decnet-ttp.service) and `decnet ttp-backfill --since-days N`.
- `decnet ttp-backfill` walks Attacker.commands and CanaryTrigger
history, dispatches each row through the live CompositeTagger,
persists tags via repo.insert_tags (idempotent INSERT OR IGNORE).
--dry-run / --source command|canary|all / --batch-size supported.
- Backfill deliberately bypasses bus publish — historical replay
must not re-trigger SIEM/webhook fan-out per TTP_TAGGING.md
§"Bus topics" loop-prevention invariant.
- Added `iter_attacker_commands_since` / `iter_canary_triggers_since`
read-only iterators on TTPMixin + abstract bindings on
BaseRepository.
- Master-only via gating; both `ttp` and `ttp-backfill` listed in
MASTER_ONLY_COMMANDS.
Add BaseRepository.list_ttp_decky_phases(identity_uuid) returning
per-decky tag observations as (decky_id, tactic, created_at_ts) rows
ordered by creation time. Rewrite from_identity_row() to project
tactic → UKCPhase via tactic_to_ukc_phase and populate the four
phase-handoff maps (first/last_phase_per_decky,
first/last_seen_per_decky) so combined_campaign_weight finally lights
up on real DB rows — not just synthetic fixtures.
ConnectedComponentsCampaignClusterer.tick() pulls each active
identity's per-decky phase observations before projecting features.
Repo failures are non-fatal: a partial repo falls back to the empty
phase-handoff signal (legacy behavior) so the worker stays up.
tests/clustering/test_ttp_phase_handoff.py pins the production-row
pair clearing CAMPAIGN_EDGE_THRESHOLD on a C2 → DISCOVERY hand-off —
the trip-wire that says the whole project paid off.
commands_by_phase_on_decky itself stays empty on the production path:
it is consumed only by the synthetic-fixture similarity surface, and
the phase-handoff edge does not use it. Synthetic fixtures still
populate it directly via from_synthetic_identity.
Dialect-split: portable rollup queries on TTPMixin; bulk insert with
ON CONFLICT DO NOTHING / INSERT IGNORE in the per-dialect repos.
Confidence-floor (< 0.3) drop applied at mixin layer before the
dialect hook. BaseRepository now declares the six TTP methods abstract.
Tests in tests/web/db/test_ttp_repo.py flipped from pytest.fail stubs
to real dual-backend behavioral tests; tests/ttp/test_confidence.py
drop-below-floor xfail removed.
Replace repo: BaseRepository with a structural TopologyRepository protocol
in persistence.py and allocator.py. All read methods now return typed DTOs
(TopologySummary, LANRow, DeckyRow, EdgeRow) instead of raw dicts, eliminating
silent field-shape regressions across the topology subsystem.
TopologySummary gains email_personas and language_default so api_personas.py
can continue reading those fields via attribute access. hydrate() converts
DTOs to dicts before passing to _backfill_decky_configs, keeping the mutable
working-state function dict-based at its boundary. All production callers
(router handlers, mutator, CLI, heartbeat) migrated from dict/get access to
attribute access. 134 tests pass.
Two related fixes that came out of running the W5 tests locally:
1. tests/__init__.py — empty file, makes 'tests/' a package so pytest
stops inserting it into sys.path. Without it, 'tests/docker/'
(the docker-image test category) shadowed the installed docker SDK
on every engine-touching test in the repo:
module 'docker' has no attribute 'DockerClient'
Pytest's default --import-mode=prepend was the culprit; making
tests/ a package is the cheapest fix and doesn't change
--import-mode for the whole tree.
2. delete_topology_decky / delete_topology_edge / delete_lan grow an
'enforce_pending: bool = True' kwarg. Default preserves the HTTP
CRUD guard (api_decky_crud / api_edge_crud / api_lan_crud get the
409 for free). apply_remove_decky / apply_detach_decky /
apply_remove_lan now pass enforce_pending=False — the mutator
queue is the live-editing surface and has its own active-topology
gating; the repo's pending-only guard was for design-time CRUD
that mustn't bypass it. Without this, apply_remove_decky was
silently broken on active topologies pre-W5; W5's new test
surfaced it on first run.
10/10 new W5 tests pass; 58/58 across mutator + topology suites.
POST /api/v1/canary/tokens grows an optional topology_id field. When
present, the server hydrates the topology, validates the named decky is
in it, and resolves the docker container via
planter.resolve_topology_container — <name>-ssh if the decky exposes ssh,
else the topology base container. Absent ⇒ fleet semantics, unchanged.
The token row gets a nullable topology_id column (no migration helper
per pre-v1 policy). GET /api/v1/canary/tokens accepts ?topology_id= as
a filter. DELETE re-resolves the container at revoke time so a
redeployed topology is still reachable.
422 when the named decky isn't in the topology; 404 when the topology
itself doesn't exist.
