• source is parquet (served from the archive) or raw (live collector file) — same columns either way.
• Column order matches the data schema.
• Rows before window_start have phase = "preopen" — recording starts 60 seconds early so consecutive windows overlap with no blind spot. De-duplicate on (slug, ts_unix) if you concatenate overlapping files.
