build_site_finder_report (§22) takes ~30-180s → runs in a background Celery task,
not inline on the sync /analyze endpoint.
- repository: latest_run_for gains keyword-only schema_version (default None keeps
v_analysis_runs_latest behavior, backward-compat); when given, reads base
analysis_runs filtered by schema_version ORDER BY created_at DESC LIMIT 1 — fetches
the latest analyze-1.0 site-analysis run even when newer 1.0 (§22) rows exist on top
(index-served via 127's (cad_num, created_at DESC)).
- new workers/tasks/forecast.py::forecast_site_finder_report: reads latest analyze-1.0,
runs the §22 orchestrator, persists SiteFinderReport.as_dict() as a 1.0 run via
persist_analysis_run. Graceful: no base run / compute error → logger + return None
(worker not crashed). time_limit=900/soft=840 (no global limit). Registered in include.
Prod-confirmed: analyze-1.0 result carries the full analyze dict (competitors+district)
→ orchestrator input valid. Endpoint trigger (3b-ii) + §9.x untouched. 943 tests pass;
code-review APPROVE (contracts verified vs real as_dict(); status done→complete normalized,
no IntegrityError). Refs #994#961.
REAL code-level cause (prod-confirmed, 2 parcels: "Geometry type (Polygon) does
not match column type (MultiPolygon)") of single-contour parcels stuck "fetching"
— complements migrations 129/130 (which fixed the cad_parcels NOT NULL chain).
F1: _save_parcel/_save_quarter now ST_Multi() the geom so single-contour Polygons
fit the MultiPolygon columns (migr 93/58), mirroring the bulk_harvest paths.
F2: _save_building rewritten to the wide cad_buildings schema (migr 92):
quarter_cad_number (was quarter_cad_num → UndefinedColumn), _safe_int(floors)
(range strings → NULL), source='nspd' NOT NULL.
F3: upsert_features wraps each feature in begin_nested() SAVEPOINT so one bad
feature no longer aborts the whole quarter snapshot (backend.md rule; mirrors
grid-walk). New tests/workers/test_nspd_geo.py + savepoint tests. 89 passed.
REOPENED. L3 future-supply rows are computed per (district_name, dev_group_name)
but dev_group_name was never a key column — only embedded in method text. With
complex_id/obj_class NULL for L3, every dev_group of a district collapsed to one
upsert key → ~95.6% loss. Ground-truth (Академический, prod): should be 13,808
units / 15 dev_groups / 54 objects; only 1 row / 607 units survived.
Migration 128: ADD COLUMN supply_layers.dev_group_name TEXT + rebuild
uq_supply_layers_logical to (layer, district_name, complex_id, obj_class,
dev_group_name, source, snapshot_date) NULLS NOT DISTINCT (L1/L2 dev_group_name
NULL stays transparent → their dedup unchanged; L3 distinct groups no longer
collapse). Dry-run-verified vs prod catalog (applies clean, ROLLBACK clean).
Worker: SupplyLayerRow gains dev_group_name (L1/L2=None, L3=group); _UPSERT_SQL
adds it to INSERT/VALUES (CAST(:dev_group_name AS text)) + ON CONFLICT (key col,
not in DO UPDATE SET). Service+worker regression tests assert same-district/
different-dev_group → distinct keys (no collapse). 234 supply tests pass.
Deploy applies migration before container restart; collapsed data self-heals on
next supply_layers_refresh. Verification = prod re-measure post-deploy.
