Calibration exports¶

Immutable snapshots for offline review — not regulatory submissions.

CSV (baseline)¶

make export-calibration
# or
make export-calibration-csv

Writes under artifacts/calibration/<YYYYMMDDTHHMMSSZ>/:

Per-view CSV files
metadata.json (redacted host, row counts, git/package hints when available — no secrets)

uv sync --extra parquet
make export-calibration-parquet

Requires pyarrow; otherwise the command fails with a clear message.

CALIBRATION_EXPORT_DRY_RUN=1 writes a minimal metadata.json without querying views — useful when Postgres is unavailable.

CALIBRATION_EXPORT_DIR, CALIBRATION_EXPORT_FORMATS, CALIBRATION_EXPORT_INCLUDE_PARQUET — see .env.example.
