+"""Celery task: harvest ИРД-overlay геометрии из НСПД → ``ird_overlays`` (м.132).
+
+#1067 (Site Finder v2 / слой ИРД для analyze, «GG-форсайт»), foundation B5. Для каждого
+квартала ЕКБ (66:41:*) grid-walk'ит готовые НСПД-слои ИРД и UPSERT-ит фичи в ``ird_overlays``
+по ключу ``uq_ird_overlays_feature`` (source_layer_id, geom_data_id). analyze читает overlap
+участка через ``ST_Intersects``.
+
+НСПД отдаёт по фиче ТОЛЬКО геометрию (EPSG:3857) + reg_numb_border + category/subcategory
+(разведка 2026-06-06, vault research/NSPD_IRD_Layers_Automation_Recon_Jun06). content_* (тип/
+ВРИ/параметры) дорезолвятся отдельно из ЕКБ-геопортала (C8/D9) и здесь НЕ трогаются.
+
+Harvest-набор = готовые ИРД-слои (ID зашиты в nspd_client.LAYERS):
+  ЗОУИТ 37577-37581 (ОКН/инж/природа/охрана/иные) · 875838 терзоны ПЗЗ (геометрия) ·
+  875840 территории ОКН · 875845 ООПТ · 875866 лесничества · 875832/875835 береговые линии.
+
+Mirror conventions (supply_layers_refresh.py / backend.md):
+  • SessionLocal() + try/finally close; logger (не print).
+  • SAVEPOINT per-row (``with db.begin_nested():``) — одна битая фича не валит батч; commit в конце.
+  • CAST(:x AS type) — НИКОГДА :x::type (psycopg v3). Геометрия: ST_Transform(3857→4326).
+  • ON CONFLICT обновляет геометрию/reg/category/subcategory/raw_props/fetched_at; content_*
+    НЕ трогает (их пишет резолвер D9 — re-harvest не затирает резолвленный тип/регламент).
+  • Сбой одного квартала/слоя не валит весь прогон.
+
+Расписание — еженедельно (beat_schedule.py: ird-harvest-weekly). Геометрия зон стабильна,
+чаще не нужно.
