test_queue.py::TestRetry::test_finalize_job_requeue_then_fail failed in the
self-hosting environment because launcher._finalize_job classifies a non-zero
exit by reading the tail of <settings.runs_dir>/<run_id>.log. settings.runs_dir
defaults to the live prod dir /app/data/runs, which on the host holds REAL
accumulated agent logs; a real 2.log containing "429" flips the expected
'permanent' classification to 'transient', requeueing the job instead of
marking it 'failed'. This is ambient prod pollution, not a code fault.
Add an autouse _isolate_runs_dir fixture (mirroring _no_telegram /
_disable_merge_verify) that redirects settings.runs_dir to a per-test tmp dir
so _run_log_path() resolves to a non-existent file and classify_log_file()
returns the documented 'permanent' default. Full suite: 1617 passed. src/**
untouched.

Add the `watchdog/` package (thin Python-3.12 stdlib-only daemon) and the
`orchestrator-watchdog` compose service — the brain half of the domain-0
observability pair. F1a (ORCH-099) exposes GET /metrics raw signal; F1b reads it,
augments with host / container / dependency probes, runs each signal through a
generalised pure decision function (decide(signal_active, prev, now, cooldown),
a strict superset of disk_watchdog.decide_action) with per-signal in-memory
dedup/throttle/recovery, and alerts over its OWN independent Telegram channel.
Key properties (ADR-001):
- Observer separated from observed: separate container; /metrics not answering is
itself the master `orch_down` alarm (debounced K ticks — no flap on a hiccup).
- Strictly read-only: docker.sock GET-only + mounted :ro (double guard), host
paths :ro, no DB/disk writes, no process control — self-hosting-safe.
- never-raise on three levels (per-source/per-tick/per-send) + WATCHDOG_ENABLED
kill-switch (disabled -> inert idle-loop, not exit).
- Disk anti-duplicate (D6): disk_watchdog (ORCH-063) stays sole owner of the 85%
alert; sidecar carries orch_down + an opt-in 97% ceiling (default off).
- NO import from src/** (C-1); src/**, STAGE_TRANSITIONS, QG_CHECKS, check_*, DB
schema — untouched. env_file optional so a missing .env.watchdog never breaks
`docker compose up` for the prod orchestrator.
Tests: tests/watchdog/ (TC-01…TC-13) + full tests/ regression green (TC-14).
Docs: CHANGELOG, .env.example canon (WATCHDOG_*); architecture README + adr-0033
authored at the architecture stage.
