Celery task tasks.supply_layers_refresh computes L1/L2/L3 supply layers per
Sverdlovsk district via supply_layers.compute_all_layers and UPSERTs into
supply_layers (m.125) on uq_supply_layers_logical, updating all mutable cols
(units/area/expected_online_date/confidence/method/computed_at), never the key.
Coherent single date.today() snapshot_date across the batch; per-row SAVEPOINT
(begin_nested) so a bad row/district can't abort the weekly batch; per-district
guard. District set is data-driven (UNION of objective_lots.district and
domrf_kn_objects.district_name region_cd=66), not hardcoded.
Registered weekly Mon 06:00 МСК (after scrape_kn 04:15 that refreshes free_flats,
the L2 source). Adds the task module to celery_app include (beat resolves by
name). 11 unit tests asserting the ON CONFLICT contract + savepoint + coherent
snapshot.
После Sub-PR B (#260, merged 8ebcd15) переключения search_by_quarter на
grid-walk dispatch — beat schedule безопасно re-enable'ить:
- harvest_quarter возвращает полноценные dumps (territorial_zones + ЗОУИТ +
risk zones + engineering structures) вместо 0-3 features
- per-instance semaphore (PR #260) защищает от cross-loop binding bug
- soft/hard time_limit 600/900s — задача успевает завершиться
Schedule: Mon 01:00 UTC (04:00 МСК), batch_size=50 ограничивает WAF burst,
max_age_days=90 для регулярного refresh + новые quarters (fetched_at IS NULL).
Полный ЕКБ back-fill (11k+ quarters в cad_quarters_geom) займёт несколько
недель при batch_size=50/week; в production будет ускорено manual trigger
admin endpoint'ом если нужно.
Closes#231.
PKK6 ArcGIS sync для pzz_zones_ekb (0 rows live) — задача и admin endpoint
уже существуют, но beat schedule отсутствовал. Schedule: 1st of month, 03:00 МСК.
Closes#233
