New POST /swarm/heartbeat on the swarm controller. Workers post every
~30s with the output of executor.status(); the master bumps
SwarmHost.last_heartbeat and re-upserts each DeckyShard with a fresh
DeckyConfig snapshot and runtime-derived state (running/degraded).
Security: CA-signed mTLS alone is not sufficient — a decommissioned
worker's still-valid cert could resurrect ghost shards. The endpoint
extracts the presented peer cert (primary: scope["extensions"]["tls"],
fallback: transport.get_extra_info("ssl_object")) and SHA-256-pins it
to the SwarmHost.client_cert_fingerprint stored for the claimed
host_uuid. Extraction is factored into _extract_peer_fingerprint so
tests can exercise both uvicorn scope shapes and the both-unavailable
fail-closed path without mocking uvicorn's TLS pipeline.
Adds get_swarm_host_by_fingerprint to the repo interface (SQLModel
impl reuses the indexed client_cert_fingerprint column).
Agents already exposed POST /teardown; the master was missing the plumbing
to reach it. Add:
- POST /api/v1/swarm/hosts/{uuid}/teardown — admin-gated. Body
{decky_id: str|null}: null tears the whole host, a value tears one decky.
On worker failure the master returns 502 and leaves DB shards intact so
master and agent stay aligned.
- BaseRepository.delete_decky_shard(name) + sqlmodel impl for per-decky
cleanup after a single-decky teardown.
- SwarmHosts page: "Teardown all" button (keeps host enrolled).
- SwarmDeckies page: per-row "Teardown" button.
Also exclude setuptools' build/ staging dir from the enrollment tarball —
`pip install -e` on the master generates build/lib/decnet_web/node_modules
and the bundle walker was leaking it to agents. Align pyproject's bandit
exclude with the git-hook invocation so both skip decnet/templates/.
Introduces the master-side persistence layer for swarm mode:
- SwarmHost: enrolled worker metadata, cert fingerprint, heartbeat.
- DeckyShard: per-decky host assignment, state, last error.
Repo methods are added as default-raising on BaseRepository so unihost
deployments are untouched; SQLModelRepository implements them (shared
between the sqlite and mysql subclasses per the existing pattern).
Adds the server-side wiring and frontend UI to surface files captured
by the SSH honeypot for a given attacker.
- New repository method get_attacker_artifacts (abstract + SQLModel
impl) that joins the attacker's IP to `file_captured` log rows.
- New route GET /attackers/{uuid}/artifacts.
- New router /artifacts/{decky}/{service}/{stored_as} that streams a
quarantined file back to an authenticated viewer.
- AttackerDetail grows an ArtifactDrawer panel with per-file metadata
(sha256, size, orig_path) and a download action.
- ssh service fragment now sets NODE_NAME=decky_name so logs and the
host-side artifacts bind-mount share the same decky identifier.
Adds BaseRepository.add_logs (default: loops add_log for backwards
compatibility) and a real single-session/single-commit implementation
on SQLModelRepository. Introduces DECNET_BATCH_SIZE (default 100) and
DECNET_BATCH_MAX_WAIT_MS (default 250) so the ingester can flush on
either a size or a time bound when it adopts the new method.
Ingester wiring is deferred to a later pass — the single-log path was
deadlocking tests when flushed during lifespan teardown, so this change
ships the DB primitive alone.
Cold start fetched all logs in one bulk query then processed them in a tight
synchronous loop with no yields, blocking the asyncio event loop for seconds
on datasets of 30K+ rows. This stalled every concurrent await — including the
SSE stream generator's initial DB calls — causing the dashboard to show
INITIALIZING SENSORS indefinitely.
Changes:
- Drop _cold_start() and get_all_logs_raw(); uninitialized state now runs the
same cursor loop as incremental, starting from last_log_id=0
- Yield to the event loop after every _BATCH_SIZE rows (asyncio.sleep(0))
- Add SSE keepalive comment as first yield so the connection flushes before
any DB work begins
- Add Cache-Control/X-Accel-Buffering headers to StreamingResponse
- Add `get_repository()` factory function to select DB implementation at runtime via DECNET_DB_TYPE env var
- Extract BaseRepository abstract interface from SQLiteRepository
- Update dependencies to use factory-based repository injection
- Add DECNET_DB_TYPE env var support (defaults to sqlite)
- Refactor models and repository base class for cross-dialect 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.
