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".
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.
Adds the three signal columns motivated by the manual keystroke
analysis in DEBT-036 directly to the SessionProfile table. Pre-v1 so
we modify the schema in place — Alembic arrives at v1.
Columns:
- kd_top_bigrams (TEXT) — JSON of top-N most-common digraphs with
mean IAT per bigram. Complements kd_digraph_simhash ("same typist?")
with "same typist in same mental state?" (tired / rested / distracted
shifts bigram-specific IATs measurably).
- kd_start_of_action_latency (REAL/DOUBLE) — median IAT of the first
keystroke after an idle gap > 1s. Separates "initiating a command"
from "executing a remembered one"; real humans have measurable
start-of-action latency, bots don't.
- kd_pause_hist_burst / _think / _distracted (INT) — three-bucket
histogram (counts, <0.2s / 0.2-1.5s / >1.5s). More discriminating
than the existing flat burst_ratio / think_ratio pair: C2 operators
concentrate in burst with a thin tail; opportunistic humans have a
fat think bucket and a long distracted tail.
Both backends get an idempotent ADD COLUMN migration
(_migrate_session_profile_table) wired into initialize() alongside
the existing _migrate_attackers_table path — guards on PRAGMA
table_info (SQLite) / information_schema.COLUMNS (MySQL) so reruns
are safe.
PII discipline comment on kd_digraph_simhash and kd_top_bigrams:
both operate on bigram CHARACTERS, never on raw input stream content.
Attacker passwords typed over SSH must not land here.
Test updated for the MySQL initialize() migration-order contract.
Populates Attacker.country_code + country_source (MVP) using the five
RIR delegated-stats files (ARIN/RIPE/APNIC/LACNIC/AFRINIC). Offline,
license-free, no outbound traffic that could burn honeypot stealth.
- decnet.geoip package with factory/base/lookup + rir/ subpackage
(fetch/parse/provider) mirroring the db + bus factory convention
- Profiler._build_record calls enrich_ip on every upsert
- Idempotent ALTER TABLE migrations for both SQLite and MySQL
- decnet geoip refresh/lookup CLI (master-only)
- /var/lib/decnet/geoip seeded by decnet init
- DECNET_GEOIP_ENABLED=false kill-switch; set in tests/conftest.py so
unit tests never trigger the first-access fetch
- aiomysql → asyncmy on both sides of the URL/import (faster, maintained).
- Pool sizing now reads DECNET_DB_POOL_SIZE / MAX_OVERFLOW / RECYCLE /
PRE_PING for both SQLite and MySQL engines so stress runs can bump
without code edits.
- MySQL initialize() now wraps schema DDL in a GET_LOCK advisory lock so
concurrent uvicorn workers racing create_all() don't hit 'Table was
skipped since its definition is being modified by concurrent DDL'.
- sqlite & mysql repo get_log_histogram use the shared _session() helper
instead of session_factory() for consistency with the rest of the repo.
- SSE stream_events docstring updated to asyncmy.
- Extract dialect-agnostic methods to BaseRepository
- Keep only SQLite-specific SQL and initialization in SQLiteRepository
- Reduces duplication for upcoming MySQL backend
- Maintains 100% backward compatibility
New GET /attackers/{uuid}/commands?limit=&offset=&service= endpoint
serves commands with server-side pagination and optional service filter.
AttackerDetail frontend fetches commands from this endpoint with
page controls. Service badge filter now drives both the API query
and the local fingerprint filter.
API now accepts ?service=https to filter attackers by targeted service.
Service badges are clickable in both the attacker list and detail views,
navigating to a filtered view. Active filter shows as a dismissable tag.
Migrate Attacker model from IP-based to UUID-based primary key with
auto-migration for old schema. Add GET /attackers (paginated, search,
sort) and GET /attackers/{uuid} API routes. Rewrite Attackers.tsx as
a card grid with full threat info and create AttackerDetail.tsx as a
dedicated detail page with back navigation, stats, commands table,
and fingerprints.
