WP 22 (sharp-hpi-quebec/data/processed/clean_transactions.parquet), derived by WP 22 scripts 01–04 from the SQLite .backup of the Vrai Prix production database M3U96a:~/apps/vrai-prix/data/vraiprix.db taken 2026-10-21 00:30 America/Toronto (sha256 2816d8dd… pinned in WP 22) |

Vrai Prix (www.vrai-prix.com) is the author's own platform; the registered-sales table is assembled from the public Quebec land register and the municipal assessment rolls (MAMH). Use is authorized for research by the owner; individual records are not redistributed (addresses). Agents never receive street addresses: coordinates are rounded to 3 decimals and the municipality/borough name is given instead.
Immo-Ka listings (M4M64b ~/apps/immo-ka/data/immoka.db, 479,265 listings first seen 2026-08-12 → 2026-10-27, 195,503 linked to a roll unit) were audited (docs/data_access_checklist.md) but are not used in the main arms: coverage starts after the test window and ask prices would create an information asymmetry across arms. They are reserved for the prospective-set descriptive analysis (scripts/60_fetch_prospective.py).
To rerun from scratch: copy the WP 22 outputs here under the same names (or regenerate them with the WP 22 pipeline from a Vrai Prix snapshot), then make data.
