| ### C. Dataset builder (scripts/, typescript or python) | ||
| Why: calibration needs ≥ 20 labeled nights; today the join lives in three scratch scripts. | ||
| What: `scripts/sleep-stage-dataset.py <export.xml|export dir> <biometrics.db> --side left --out dataset.csv` emitting one row per pod vitals sample (about one per minute): `night, side, ts, watch_stage, hr, hrv, br, movement, hr_quality` plus `watch_hr` when within 60 s. Reuse `parse.py`/`eval.py` logic. Also `--summary` printing per-night agreement for the current classifier and the always-light baseline. |

Update Workstream C to reflect the delivered builder.
This line says the join lives in scratch scripts and directs the owner to reuse parse.py and eval.py. This PR adds the dataset builder and removes those scripts. Update the workstream to distinguish the implemented builder from remaining work, such as collecting more labeled nights and confirming --from-db parity.
Per the PR summary, this PR adds the builder and removes parse.py and eval.py.

| Acceptance: | ||
| - Reproduces the first three rows of the table in §1 for the two nights (±1 point). | ||
| - Rejects nights where pod-vs-Watch HR MAD > 8 bpm with a warning (side mismatch guard). | ||
| - README in this folder documents how to pull a consistent copy of the DB (SQLite backup API on the pod, or `scp -P 8822 root@<pod>:/persistent/sleepypod-data/biometrics.db{,-wal}` while the writers are quiet). |

official SQLite WAL documentation behavior when the WAL file is invalid, overwritten, or missing
💡 Result:
The official SQLite documentation describes three distinct cases:
- **Missing WAL:** The `-wal` may be absent normally after a clean close and checkpoint. If it is missing on first open, recovery has nothing to replay; the main database is read as-is. But if the WAL held committed transactions not yet checkpointed, separating or deleting it can lose those transactions or leave the database corrupted. Keep the WAL with the database when copying or moving it. ([sqlite.org](https://www.sqlite.org/walformat.html))
- **Invalid or truncated WAL:** During recovery, SQLite scans WAL frames and verifies checksums. It stops at the first invalid checksum (or end of file) and rebuilds the WAL index using the valid frames up to that point. The documentation does not promise that this makes a database safe if the WAL was damaged or altered; frames missing from the valid prefix may represent committed data. ([sqlite.org](https://www.sqlite.org/walformat.html))
- **Overwritten WAL:** SQLite itself reuses a WAL by resetting it only under defined checkpoint and locking conditions. That is different from an application or external process overwriting it. The docs warn that removing or separating the WAL can lose committed transactions or corrupt the database; they do not establish a guaranteed outcome for arbitrary overwriting. ([sqlite.org](https://www.sqlite.org/walformat.html))
**Practical guidance:** Don’t delete, replace, or copy a live database without its `-wal` file. To remove the WAL safely, SQLite’s guidance is to open the database and close it cleanly. ([sqlite.org](https://www.sqlite.org/wal.html))

Add a local destination to the scp command.
Shell brace expansion produces two remote operands. scp treats the first as the source and the second as the destination, so this command can overwrite the pod's biometrics.db-wal with the main database file. SQLite has no safeguard for arbitrary external WAL replacement; this can discard committed data that has not been checkpointed and may leave the database inconsistent.
Proposed fix
- scp -P 8822 root@<pod>:/persistent/sleepypod-data/biometrics.db{,-wal}
+ scp -P 8822 root@<pod>:/persistent/sleepypod-data/biometrics.db{,-wal} .🤖 Prompt for AI Agents

Summary
Workstream C of
docs/research/sleep-stage-calibration/PLAN.md. Classifier v2 needs at least 20 Watch-labeled nights. Until now the join between Apple Health exports and pod vitals lived in three scratch scripts.scripts/sleep-stage-dataset.pystreams a Health export (or readsreference_stageswith--from-db) and joins it withvitals,movementandvitals_qualityfrom a copiedbiometrics.db. It writes one CSV row per pod vitals sample:night,side,ts,watch_stage,hr,hrv,br,movement,hr_quality,watch_hr. Stdlib only.--max-hr-mad.--summaryreports per-night agreement with the Watch for a faithful port ofclassifySleepStages. The port covers the outlier filter, 5-minute movement buckets, phase-1 rules, A-B-A smoothing and transition constraints. It reports the deployed movement-only mode, the iOS rule set and an always-light baseline.--from-dbreadsreference_stages(side, source, start, end, stage)from the parallel ingest work. If the table is missing, it exits with a clear message.README.mdcovers pulling the DB withscp -P 8822 …biometrics.db{,-wal}, the export, the CSV columns and the summary.parse.pyandeval.pyare removed because the new script supersedes them.feat2.pynow reads the CSV for the windowed-feature and tree exploration.This branch is based on
docs/sleep-stage-calibration-plan, so it also carries the plan commit, which has no PR of its own.Reproduced PLAN.md section 1 on the 2026-10-10 DB copy and export:
The guard rejects 2026-10-01 on the right side at an HR MAD of 11.8 bpm. Results stay within 1 point with padding set to 0, 5, 10 or 30 minutes.
