+## ANCPI ePay — CF Extract Ordering
+
+### Overview
+
+Orders CF extracts (Carte Funciară) from ANCPI ePay (epay.ancpi.ro).
+Separate auth system from eTerra. Uses credits (prepaid, 1 per extract).
+
+### Critical Discovery: ID Mapping
+
+- **ePay internal county IDs = eTerra WORKSPACE_IDs** (CLUJ=127, ALBA=10, etc.)
+- **ePay UAT IDs = SIRUTA codes** (Cluj-Napoca=54975, Florești=57706)
+- This means ZERO discovery calls needed — use GisUat.workspacePk + siruta directly
+
+### Auth Flow (OpenAM)
+
+1. GET login page with `module=SelfRegistration&goto=http://epay.ancpi.ro:80/epay/LogIn.action`
+2. POST credentials (`IDToken1`, `IDToken2`) → gets `AMAuthCookie` (NOT `iPlanetDirectoryPro`)
+3. Navigate to `http://epay.ancpi.ro:80/epay/LogIn.action` (HTTP, not HTTPS!) for JSESSIONID
+4. Session TTL: ~1 hour
+
+### Order Flow (4 requests per batch)
+
+1. `POST AddToCartOrWishListFromPost.action` × N → basketRowIds
+2. `POST EpayJsonInterceptor.action` (multipart) × N → `reqType=saveProductMetadataForBasketItem` + `productMetadataJSON`
+3. `POST EditCartSubmit.action` → `goToCheckout=true` (ONE submit for ALL items)
+4. `GET CheckoutConfirmationSubmit.action` → confirms order
+5. Poll `ShowOrderDetails.action?orderId=...` → parse documents from HTML-encoded JSON (`&quot;` → `"`)
+6. `POST DownloadFile.action?typeD=4&id=...` with `Content-Type: application/pdf` in REQUEST header
+
+### ePay Endpoint Gotchas
+
+1. **EpayJsonInterceptor uses form-urlencoded** (NOT JSON): `reqType=nomenclatorUAT&countyId=127`
+2. **saveProductMetadataForBasketItem uses multipart/form-data** (form-data npm package)
+3. **CF/CAD use `stringValues[0]`** (array!), not `stringValue`
+4. **Document IDs are HTML-encoded** in ShowOrderDetails: `&quot;idDocument&quot;:47301767` → decode first
+5. **DownloadFile sends Content-Type: application/pdf in the REQUEST** (not response)
+6. **EditCartSubmit returns 200** (not redirect) — Angular does client-side redirect to CheckoutConfirmation
+7. **SearchEstate needs `identificator`/`judet`/`uat`** (not `identifier`/`countyId`/`uatId`), plus requires internal IDs
+8. **MinIO metadata must be ASCII** — strip diacritics from values (`Florești` → `Floresti`)
+
+### Dedup Protection
+
+- **Queue level**: batch key = sorted cadastral numbers, 60s dedup window
+- **API level**: optional `nonce` field, 60s idempotency cache
+- **Test endpoint**: 30s dedup on hardcoded test parcels
+

+| `services/epay-storage.ts` | MinIO storage helpers |
+| `services/epay-counties.ts` | County index mapping (legacy, not needed for ordering) |

+
+### DB Model: CfExtract
+
+- `orderId` — shared across batch items (NOT unique)
+- `nrCadastral`, `siruta`, `judetName`, `uatName` — parcel identity
+- `status` — pending|queued|cart|ordering|polling|downloading|completed|failed|cancelled
+- `minioPath` — `parcele/{nrCadastral}/{idx}_Extras CF_{nrCadastral} - {DD-MM-YYYY}.pdf`
+- `expiresAt` — 30 days after documentDate
+- `version` — increments on re-order for same cadastral number
+
+### Credentials
+
+- Env vars: `ANCPI_USERNAME`, `ANCPI_PASSWORD` (hardcoded in docker-compose for Portainer CE)
+- Default solicitant: ID `14452` (Beletage persoană juridică)
+- MinIO bucket: `ancpi-documente`
