feat(duckpipe): maille quartier IRIS — prix et gap qualité-prix infra-communaux - #11
Merged
Conversation
…RIS)
Compute the quality-price gap below city level using the INSEE IRIS mesh
(ADR-0015):
- ingest CONTOURS-IRIS (IGN/INSEE FlatGeoBuf) as a bronze source and a
silver iris_geom (PLM arrondissement codes preserved, never filtered
against commune_geom)
- extend prix_millesime with a dvf_points output (unit-level geolocated
mutations) and pool vintages in the new iris_prix silver: mono-IRIS
communes matched by code, multi-IRIS ones by ST_Intersects constrained
to the mutation's commune, boundary ties broken by smallest code_iris
- new gold score_quartier: n_prix_iris normalized with the communal _norm,
gap_iris = inherited commune score - n_prix_iris, weighted variant by
the commune's financial accessibility
- web export choropleth/iris-high/{dept}.geojson (multi-IRIS communes
only) with additive meta keys nb_iris/nb_iris_scores; schema_version
stays 1
- DQ rules for both silver tables, gold quartier validation, DVF->IRIS
match rate in the silver report; new Cloud Workflows steps
…tion The local dvf_full_2022.csv.gz cache was re-downloaded on 2026-06-30 and now yields 31250 communes (+2 vs the reference base built on the 2026-06-25 file): geo-dvf republishes vintages under the same latest URL. Count re-derived from the current file; the reference database was not rebuilt. Pre-existing failure on main, unrelated to the IRIS feature.

Résumé
Descend le prix et l'écart qualité-prix à une maille plus fine que la commune : le quartier (IRIS INSEE), cf. ADR-0015.
Commit séparé : mise à jour de la référence `test_prix_millesime[2022]` (31 248 → 31 250), dérive du cache geo-dvf préexistante sur main, sans lien avec la fonctionnalité.
Validation
Note pour le run
La CI (`deploy.yml`) redéploie l'image et le yaml Cloud Workflows au merge sur main — le run pourra être lancé ensuite sans action manuelle. Prévoir le temps de la nouvelle étape `iris_prix` (jointure spatiale ~4 M de points, quelques minutes).
