+## PHASE 7B — ParcelSync / eTerra Module (NEW — 2026-03)
+
+> GIS integration with Romania's national eTerra/ANCPI cadastral system.
+
+### 7B.01 ✅ `[HEAVY]` ParcelSync Core — eTerra Client + Layer Sync (2026-03)
+
+**What:** eTerra API client with form-post auth, JSESSIONID cookie jar, session caching, paginated layer fetching. 23-layer catalog. Background sync with progress polling. PostGIS storage with GisFeature model.
+**Status:** ✅ Done. `eterra-client.ts` (~1000 lines), `sync-service.ts`, `eterra-layers.ts`, `session-store.ts`. Pagination with `maxRecordCount=1000` + page size fallbacks (500, 200). Default timeout 120s. Background sync via server singleton.
+
+---
+
+### 7B.02 ✅ `[HEAVY]` ParcelSync — Enrichment Pipeline (2026-03)
+
+**What:** Per-parcel enrichment via eTerra `/api/immovable/list`. Extracts NR_CAD, NR_CF, PROPRIETARI, SUPRAFATA, INTRAVILAN, CATEGORIE_FOLOSINTA, HAS_BUILDING, etc.
+**Status:** ✅ Done. `enrich-service.ts` with `FeatureEnrichment` type. JSONB storage in `enrichment` column.
+
+---
+
+### 7B.03 ✅ `[STANDARD]` ParcelSync — Owner Search (2026-03)
+
+**What:** Search by owner name. DB-first (ILIKE on enrichment JSON PROPRIETARI) with eTerra API fallback.
+**Status:** ✅ Done. `/api/eterra/search-owner`, `searchImmovableByOwnerName()` in client. Mode toggle in Search tab UI.
+
+---
+
+### 7B.04 ✅ `[STANDARD]` ParcelSync — Per-UAT Analytics Dashboard (2026-03)
+
+**What:** Visual dashboard per UAT with KPIs, area stats, intravilan/extravilan donut, land use bars, top owners, fun facts. CSS-only (no chart libraries).
+**Status:** ✅ Done. `/api/eterra/uat-dashboard` with SQL aggregates. `uat-dashboard.tsx` component. Dashboard button on each UAT card in DB tab.
+
+---
+
+### 7B.05 ✅ `[STANDARD]` ParcelSync — Health Check + Maintenance Detection (2026-03)
+
+**What:** Ping eTerra every 3min, detect maintenance by keywords in HTML, block login when down, show amber "Mentenanță" state.
+**Status:** ✅ Done. `eterra-health.ts` singleton, `/api/eterra/health` endpoint, session route blocks login, UI shows amber pill with message extraction.
+
+**Bugs found & fixed during ParcelSync development:**
+- Timeout 40s too low for geometry pages → increased to 120s
+- `arr[0]` access fails TS strict even after length check → assign to const
+- `?? ""` on `{}` typed field produces `{}` → use `typeof` check
+- Prisma `$queryRaw` result needs explicit cast + guard
