-- Triggered by webhook from Daily Digest (payload includes `email_id`)
-- Downloads the PDF attachment from Gmail API
-- Fetches Paperless metadata (correspondents, document types, tags, storage paths, similar existing documents)
-- Calls GPT-4.1 to infer Paperless metadata (correspondent, doc type, tags, storage path, filename, date)
-- Uploads PDF to Paperless, polls task status, patches metadata on the created document
-- Sends Telegram confirmation
+Replaces the two retired workflows below. Single core pipeline with two entry points:
 
-### 📄 Paperless — Upload Documento [Telegram] (`ZX5rLSETg6Xcymps`)
+- **Trigger 1 — Telegram**: PDF sent to bot with caption starting with "Documento" → downloads file
+- **Trigger 2 — Webhook** (`POST /webhook/paperless-upload`): called by Daily Digest with `{email_id, attachment_id, filename, hint, from}` → downloads attachment from Gmail API
 
-- Triggered by Telegram bot (user sends a PDF with caption starting with "Documento")
-- Downloads file from Telegram
-- Sends to FileWizard OCR microservice (async job), polls for result
-- Same GPT-4.1 metadata inference pipeline as above
-- Uploads to Paperless (filename = original filename without extension), patches metadata
-- Sends Telegram confirmation with link to document
-- Cleans up FileWizard: deletes processed files, then clears job history
+Both paths converge:
+- FileWizard OCR (async, polls job) → GPT-4.1 metadata inference → Paperless upload → PATCH metadata → Telegram confirmation → FileWizard cleanup
+- Dedup: if Paperless returns "duplicate", patches the existing document's metadata instead
 
-**Common pattern across all three**: GitHub Copilot token is obtained fresh at each run (`GET https://api.github.com/copilot_internal/v2/token`), then used for `POST https://api.githubcopilot.com/chat/completions` with model `gpt-4.1`.

+### 💰 Actual — Import Estratto Conto [Telegram] (`qtvB3r0cgejyCxUp`) ✅ Active
+
+Imports bank CSV statements (Banca Sella format) into Actual Budget via Telegram upload.
+
+- **Trigger**: Telegram bot, send CSV file with caption starting with "Estratto"
+- Fetches token Copilot → downloads CSV binary from Telegram
+- Parses CSV: skips SALDO rows, extracts transactions with `Id. XXXXXXXXX` as dedup key
+- Calls Actual HTTP API to fetch existing payees, categories, and transactions since `min_date`
+- Deduplicates: skips transactions already present (by `imported_id = banca-sella-{Id}`)
+- Splits remaining transactions into batches of 30
+- **Per batch**: GPT-4.1 classifies each transaction (payee, category, notes) → creates missing payees/categories on Actual → imports transactions
+- Final Telegram report: imported count, skipped, new payees/categories created
+- After report: marks Google Task "Actual - Estratto conto" in list "Finanze" as completed (non-blocking)
+
+**CSV format** (Banca Sella): `;` separator, `dd/mm/yyyy` dates, `.` decimal, Row 1 = header, Row 2 = SALDO FINALE (skip), Last row = SALDO INIZIALE (skip).
+
+### ⏰ Actual — Reminder Estratto Conto [Schedule] (`w0oJ1i6sESvaB5W1`) ✅ Active
+
+- Daily cron at 09:00 → checks Google Tasks for "Actual - Estratto conto" in "Finanze" list
+- If task exists and is not completed (due date ≤ today or no due date) → sends Telegram reminder
+- Reminder instructs to upload CSV via Telegram with caption `Estratto [mese]`
+
+**Common pattern across Paperless + Actual workflows**: GitHub Copilot token is obtained fresh at each run (`GET https://api.github.com/copilot_internal/v2/token`), then used for `POST https://api.githubcopilot.com/chat/completions` with model `gpt-4.1`.
