v0 Phase 1 of ATTRIBUTION-ENGINE.md:
* AttributionStateRow SQLModel keyed on (identity_uuid, primitive)
per ANTI direction — re-keying state rows when the v1 clusterer
merges attackers is the migration debt v0 should not bake in.
ATTRIBUTION-ENGINE.md updated with the deviation note.
* AttributionMixin: ensure_stub_identity_for_attacker, idempotent
upsert_attribution_state, get_attribution_state[_for_identity],
list_multi_actor_identities (the Phase 5 correlator's read).
* attribution.profile.{state_changed,multi_actor_suspected} bus
topics + builder; wiki Service-Bus.md updated separately.
* attribution_worker.py: subscribes to attacker.observation.>,
ensures stub identity per event, logs and continues. No merger,
no state writes, no derived events — Phase 4 wires those.
* attribution/{aggregate.py,_thresholds.py} skeletons: Phase 2
fills _aggregate_categorical, Phase 3 adds numeric+hash+dispatcher.
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.
When the prober observes a NEW hash for an
(attacker_uuid, port, probe_type) triple it has seen before — VPS
rotation, SSH server rebuild, TLS cert swap — emit a derived
attacker.fingerprint_rotated event carrying both old and new hash.
Detection is a small library (decnet.correlation.fingerprint_rotation)
called inline from the prober at each of the three emit sites
(JARM/HASSH/TCPFP). No new daemon. New AttackerFingerprintState table
holds per-triple last-hash state; Attacker.rotation_count and
Attacker.last_rotation_at are stamped on every diff. Library is sync,
fully unit-tested via injected publish_fn / syslog_fn callbacks.
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.
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.
First contract commit of TTP tagging. Shapes only — no behavior.
- TTPTag SQLModel: deterministic UUIDv5 PK; (source_kind, source_id)
discriminated provenance; nullable attacker_uuid + identity_uuid
with ON DELETE CASCADE; native sqlalchemy.JSON evidence column;
required attack_release; CheckConstraint('attacker_uuid IS NOT
NULL OR identity_uuid IS NOT NULL'); composite indexes for the
primary query patterns (identity_uuid+technique_id,
attacker_uuid+technique_id, technique_id+created_at); __init__
guard raising ValueError with both anchor names in the message
(belt-and-braces for MySQL <8.0.16 where CHECK is silent).
- compute_tag_uuid(): RFC-4122 UUIDv5 over the six tag-identity
fields under a fixed _TTP_TAG_NS. Pure, deterministic, replay-safe.
- Per-source_kind evidence TypedDicts (CommandEvidence,
IntelEvidence, EmailEvidence, CanaryFingerprintEvidence) — PII
rule lives in the type: EmailEvidence has no field for raw rcpt
addresses or body bytes.
- TTPRule + TTPRuleState tables for the DatabaseRuleStore (E.1.11).
- All symbols re-exported from decnet.web.db.models per the
package's existing convention.
Tests for invariants (CHECK behavior, evidence round-trip across
SQLite+MySQL, idempotency property, init-guard ordering) land in
E.2.1/E.2.2 with xfail-strict markers per Appendix E discipline.
- GET /topologies/services/{name}/schema serves the declared ServiceConfigField
metadata so the Inspector can auto-render forms.
- PUT /(topologies/{id}/)deckies/{decky}/services/{svc}/config persists the
validated dict (DB + compose); container untouched (Save).
- POST /(topologies/{id}/)deckies/{decky}/services/{svc}/apply persists then
force-recreates <decky>-<svc> so the new env takes effect (Apply, destructive).
- New engine helper update_service_config wires both fleet and topology paths
through the existing _persist_fleet_change / _rerender_topology_compose
machinery; emits decky.<name>.service_config_changed on the bus.
decnet.engine.services_live exposes add_service / remove_service for
both fleet and topology decky scopes. The host's _compose() wrapper
already supported per-service targeting (up --no-deps -d <svc>,
stop, rm -f); what was missing was the orchestration around it:
* add: validate against decnet.services.registry (rejects unknown +
fleet_singleton); persist the new services list; re-render the
per-scope compose file (so future redeploys reflect the change);
run docker compose up -d --no-deps --build <decky>-<svc>.
* remove: stop + rm -f the service container; persist; re-render
compose so a future up -d doesn't bring it back.
Both publish decky.<name>.service.added / .removed on the bus, with
the post-mutation services list. Topic constants added to
decnet.bus.topics; the matching wiki entry in wiki-checkout/Service-Bus.md
ships in a separate commit on the wiki repo (wiki-checkout/ is gitignored).
Four new admin endpoints:
* POST/DELETE /api/v1/deckies/{name}/services{,/svc}
* POST/DELETE /api/v1/topologies/{id}/deckies/{name}/services{,/svc}
ServiceMutationError messages are mapped at the API boundary to 404
(decky/topology missing), 409 (idempotency violation), 422 (unknown
or fleet_singleton service).
Extracts the docker-exec-with-base64-stdin pattern out of canary/planter
and orchestrator/drivers/ssh into a shared decnet.decky_io package.
Both consumers now delegate; the canary planter test still proves the
contract end-to-end.
Adds POST/DELETE /api/v1/deckies/files for arbitrary file drops.
Container resolution is shared with the canary path: topology_id absent
means fleet (<name>-ssh), present routes through resolve_decky_container
which picks <name>-ssh when the topology decky exposes ssh, else the
topology base container decnet_t_<id8>_<name>.
Path validation rejects relative paths and '..' traversal at the request
model layer. Bad base64 → 400; unknown topology → 404; decky not in
topology → 422; docker exec failure → 409.
