## Scheduler
`pipekit/scheduler.py` runs a single daemon thread (started via FastAPI lifespan in `api/app.py`). It wakes every 60 s, reads all enabled schedules, and fires `run_group` for any whose next cron occurrence has passed since `last_fired_at`. `last_fired_at` is written to the DB before the run thread is spawned — prevents double-fire if a run is slow or pipekit restarts mid-run. Uses `croniter` for cron expression evaluation.

- Python 3.10+, FastAPI, Uvicorn, Jinja2, PyYAML, SQLite3 (stdlib), croniter
- `python-multipart` required for HTML form POSTs (not auto-installed as a FastAPI transitive dep)
- Frontend: HTMX (CDN) + vanilla JS; Alpine.js is NOT loaded despite being listed in older docs

- Runs as the `pipekit` system user; venv at `/opt/pipekit/.venv` owned by that user; secrets at `/etc/pipekit/secrets.env` (mode 0640, group pipekit)
