End-to-end: ``python -m orchestrator --target-pid <pid> --duration N`` now
writes a complete episode directory matching docs/data-model.md, with phase
labels, events, and a 10 Hz host /proc telemetry stream. No VM yet — pid is
arbitrary so we can validate the loop against e.g. ``sleep 5`` while the lab
side comes up.
collectors/proc_qemu.py — parses /proc/<pid>/{stat,io,status} (handles parens
in comm), single-shot collect_once(), and a stop-event-driven run_loop()
that ticks at a fixed cadence and exits when the pid disappears. Tagged
``available_in_deployment: false`` per the threat-model doc.
orchestrator/episode.py — EpisodeRunner: creates data/episodes/<ulid>/,
atomic meta.json, events.jsonl + labels.jsonl writers, drives the collector
in a thread for duration_s, writes done.marker last so the shipper never
sees a half-finished episode.
orchestrator/ulid.py — tiny 26-char Crockford-base32 ULID generator.
Time-sortable, no third-party dep.
orchestrator/__main__.py — CLI entry point.
Tests (15 new, 28 total green):
- proc_qemu: real-ish stat with parens-in-comm, missing /proc/<pid>/io,
missing pid, run_loop cadence, run_loop terminates when pid disappears.
- episode: full directory shape against os.getpid(), id override,
done.marker written after meta.json finalize.
- ulid: length+alphabet, 2000-burst uniqueness, time-sortability.
Smoke-tested against ``sleep 10``: 16 rows over 1.5s at 100ms cadence,
monotonic clock, RSS stable at ~3.5 MiB as expected for an idle sleep.

One module per telemetry source. All collectors:
- Receive an
episode_id, an output directory, and a sharedt_mono_origin_ns. - Write JSONL into
data/episodes/<episode_id>/telemetry-<name>.jsonl. - Stamp every row with the same
t_mono_ns/t_wall_nsclock pair. - Stamp every row with
sourceandavailable_in_deployment(true/false). - Exit cleanly on
SIGTERMfrom the orchestrator.

The in-guest agent itself (a small Python+psutil program that runs on the
guest and writes to /dev/virtio-ports/cis490.guest.agent) lives under
vm/guest-agent/ because it is shipped into the guest at image-build time.
See docs/data-model.md for row schemas.
