Groups every flat test_*.py under the module it exercises, matching the
existing tests/{profiler,sniffer,prober,collector,correlation,cli,web,
topology,swarm,bus,updater,api,docker,geoip,...} layout. New folders:
services/, fleet/, config/, logging/, db/ (+ db/mysql/), telemetry/,
mutator/, core/.
Path-dependent __file__ references bumped an extra .parent in three
files that moved one level deeper:
- tests/sniffer/test_sniffer_ja3.py (template path)
- tests/services/test_ssh_capture_emit.py (template path)
- tests/cli/test_mode_gating.py (REPO root)
- tests/web/test_env_lazy_jwt.py (repo var)
Also drops two SQLite runtime artifacts (test_decnet.db-{shm,wal}) that
were leaking into the repo from a previous test run.
Fixes two test_service_isolation cases that patched asyncio.sleep (no
longer on the profiler main-loop hot path — same pre-existing bug I
fixed earlier in test_attacker_worker.py) by patching asyncio.wait_for
and passing interval=0.
Thin async wrapper over `systemctl` — never shell=True, always
create_subprocess_exec. Unit names are built from
`decnet-<validated-name>.service`; the regex check is defence in depth
on top of the router-level KNOWN_WORKERS validation.
Exposes start / stop / is_active / list_installed; last is cached for
30s to keep the Workers panel cheap under REFRESH spam. On non-systemd
hosts list_installed returns an empty set, so the UI renders with
every row marked not-installed instead of 500-ing.
Ingester connects the bus at startup, emits a batch-committed summary
(component/flushed/position) after each successful _flush_batch. Zero-
row flushes are suppressed so the topic stays meaningful.
Complements the collector's per-line system.log publishes: collector
signals ingress, ingester signals DB-persisted progress. Federation
forwarder (worker 8) will subscribe to the batch-committed leaf to
trigger its upstream push.
Bus stays optional: publish_safely swallows failures, get_bus() can
return None, DECNET_BUS_ENABLED=false leaves the ingestion loop fully
functional.
