a coordinator could never be given a project. Backend always allowed it.

-On a running stack:
+The databases are **not** in git — Docker volumes hold the data, and
+database dumps must never be committed (they contain user rows and signing
+material). Two supported ways to bring a fresh stack up:
 
+1. **Empty boot** — schema v2.6 auto-applies on the first boot of an empty
+`postgres_data` volume; then run the seeders:
 ```powershell
-docker compose stop api casdoor
-docker cp "backups/علی محقق/procurement.dump" procurement-postgres:/tmp/
-docker cp "backups/علی محقق/casdoor.dump" procurement-postgres:/tmp/
-docker exec procurement-postgres pg_restore -U postgres -d procurement --clean --if-exists /tmp/procurement.dump
-docker exec procurement-postgres pg_restore -U postgres -d casdoor    --clean --if-exists /tmp/casdoor.dump
-docker compose start casdoor api
+# Casdoor org + app + users (prints/generates credentials — do not commit them)
+docker compose run --rm -e CASDOOR_BASE=http://casdoor:8000 api python tools/seed_casdoor.py
+# Demo dataset (optional):
+docker exec procurement-api sh -c "cd /srv/backend && python -m tools.seed"
+
 ```
 
-Login afterwards: `ali.mohaghegh` / `hulkfuck002` (Casdoor rejects spaces
-in usernames, so «ali mohaghegh» is not a valid login name).
 
-Want demo data instead? Two seeders are still available (they create
-different users — see the Login table above):
+2. **Restore your own dump** — create dumps on the server (kept server-side,
+e.g. `/srv/erp/backups/`), never in git:
+```powershell
+docker exec procurement-postgres pg_dump -U postgres -d procurement -Fc > /srv/erp/backups/procurement-$(date +%F).dump
+docker exec procurement-postgres pg_dump -U postgres -d casdoor    -Fc > /srv/erp/backups/casdoor-$(date +%F).dump
 
-1. **App seeder** (realistic demo dataset; keeps the Casdoor org as-is):
-   ```powershell
-   docker exec procurement-api sh -c "cd /srv/backend && python -m tools.seed"
-   ```
-2. **Casdoor seeder** (creates org `inventory` + app + users razaei /
-   mousavi / mohaghegh / tester — run once after a fresh volume):
-   ```powershell
-   python backend/tools/seed_casdoor.py   # from the host, or from the api container
-   ```
+```
 
-To create a fresh dump of your own current state: stop `api` + `casdoor`,
-`docker exec procurement-postgres pg_dump -U postgres -d procurement -Fc`
-(+ the `casdoor` DB) into `backups/`, then start them again.
+
+Restore with `pg_restore --clean --if-exists` (stop `api` + `casdoor`
+first — this **replaces all data**). The scheduled backup sidecar
+(see `docs/OPERATIONS.md`) automates this.

-  badges and a «رسید جزیی» badge on the quote.
-- **One PostgreSQL instance** serves both the app (`procurement`) and Casdoor
-  (`casdoor`) — the separate casdoor-postgres container is gone (data was
-  dumped/restored; see `docs/casdoor-auth.md`).
-- **Traefik v3** is the public edge (ports 80/443); the frontend nginx only

-  (see the prod file header for the required env vars).
-- Schema runs automatically ONLY on the first boot of an empty `postgres_data` volume
-  (see `docker-entrypoint-initdb.d`); the API also runs `CREATE TABLE IF NOT EXISTS`
-  for the units-dashboard tables and `quote_attachments` at startup.
-- Invoice upload requires an `accepted`/`arrived` quote; proforma has no restriction.
-- The supplier detail page (`/suppliers/:id`) shows the purchase history with

+File downloads require an ``Authorization: Bearer`` header, but a browser

+# گزارش ادغام ایجنت هوش مصنوعی با ریپوی ERP
+
+> این سند وضعیت نهایی یکپارچه‌سازی بات تلگرام/بله (procurement AI agent) با پروژه‌ی ERP را
+> توضیح می‌دهد: مشکلی که پیش آمده بود، چه چیزی اصلاح شد، وضعیت فعلی گیت و سرور،
+> نکات امنیتی و نحوه‌ی استفاده. تاریخ آخرین به‌روزرسانی: برنچ `prod-v7`.
+
+---
+
+## ۱. مشکل چی بود؟
+
+سرویس `bot` در `docker-compose.yml` این‌طور تعریف شده بود:
+
+```yaml
+bot:
+  build:
+    context: ./bot        # ← پوشه‌ای که در گیت وجود نداشت!
+  volumes:
+    - ./bot/app:/srv/bot/app
+```
+
+اما:
+
+1. **پوشه‌ی `bot/` هیچ‌وقت کامیت نشده بود** — نه روی `prod-v7` و نه روی هیچ برنچ دیگری.
+2. کد ایجنت در پوشه‌ای به نام `ai procurement/` (با فاصله در نام) زندگی می‌کرد که روی `prod-v7` کامیت شده بود، ولی compose به آن اشاره نمی‌کرد.
+3. روی دستگاه reza.g یک **Windows Junction** (میان‌بر سطح NTFS) به نام `bot` وجود داشت که به `ai procurement` اشاره می‌کرد — به همین دلیل `docker compose build bot` فقط روی ماشین او جواب می‌داد.
+4. خود برنچ `prod-v7` هم `bot/` را در `.gitignore` (خط ۳۳) داشت.
+
+**نتیجه:** روی هر کلون تمیزی از مخزن، `docker compose build bot` شکست می‌خورد —
+همان چیزی که تیم گزارش کرد: «bot/ was never committed — prod-v7's bot is un-buildable from the repo.»
+
+## ۲. راه‌حل اعمال‌شده (راه‌حل شماره ۲)
+
+1. Junction ویندوزی `bot` حذف شد (فقط میان‌بر؛ فایلی از دست نرفت).
+2. پوشه‌ی `ai procurement/` به **`bot/`** تغییر نام یافت — با `git mv`، یعنی
+   **تاریخچه‌ی گیت هر ۴۱ فایل به‌صورت rename خالص حفظ شده** (`R` در گیت، نه حذف/افزودن).
+3. خط `bot/` از `.gitignore` ریشه حذف شد تا پوشه‌ی بات دیگر ignore نشود.
+   (`voice/` سر جایش ماند — نت‌های صوتی رuntimes هستند و نباید کامیت شوند.)
+4. اکنون `docker-compose.yml` **بدون هیچ تغییری** درست کار می‌کند:
+   `context: ./bot` و `./bot/app` دقیقاً به فایل‌های کامیت‌شده اشاره می‌کنند.
+5. همه‌چیز روی برنچ **`prod-v7`** کامیت و پوش شده تا تیم به فایل‌ها دسترسی داشته باشد.
+
+### قواعد ignore فعلی (عمدی)
+
+| مسیر | وضعیت | دلیل |
+|---|---|---|
+| `bot/.env` | ignore (توسط `bot/.gitignore`) | کلیدها و توکن‌ها — هرگز کامیت نمی‌شوند |
+| `bot/__pycache__/` و `*.pyc` | ignore | خروجی runtime پایتون |
+| `voice/` | ignore (ریشه) | فایل‌های صوتی دریافتی از بله در زمان اجرا |
+| `procurement_ai_agent.bundle` و `git_history_backup.zip` | **کامیت‌شده** | بکاپ تاریخچه‌ی اصلی ایجنت (~۲۰۰KB) |
+
+## ۳. وضعیت فعلی گیت (تاریخ این سند)
+
+- برنچ فعال: **`prod-v7`** (محلی و `origin/prod-v7` هم‌SHA).
+- درخت `prod-v7` = کل اپلیکیشن ERP (backend/frontend/…) **به‌علاوه‌ی** `bot/`
+  (کد ایجنت + Dockerfile + docs + integration) + `backend/app/routers/drafts.py`
+  (اندپوینت‌های همگام‌سازی draft بات ↔ ویزارد) + اسکیمای `bot_drafts`.
+- تاریخچه: از production (d69ec7f) یازده کامیت جلوتر — از «feat(drafts): bot_drafts schema»
+  تا «feat(bot,wizard): smart message filtering…».
+- بقیه‌ی برنچ‌های تیم (`prod-v8`، `prod-v9`، `prod_v8`، `production`) **فایل‌های بات را ندارند** —
+  ادغام این برنچ با کار جدید تیم، قدم بعدی جداگانه است (با تأیید تیم).
+
+## ۴. ⚠️ نکته‌ی امنیتی (مهم — اقدام لازم)
+
+در همان `docker-compose.yml`، مقادیر **واقعی** به‌عنوان پیش‌فرض env کامیت و پوش شده‌اند:
+
+```yaml
+PROCUREMENT_BOT_BOT_TOKEN: ${BALE_BOT_TOKEN:-1354444845:yhVMnKZBFuKaU3UW5fP1bHmknEHx99mipWw}
+PROCUREMENT_BOT_AI_API_KEY: ${AI_API_KEY:-sk-a671eab15be846d494bf0839070a3b32}
+```
+
+یعنی توکن بات بله و کلید DeepSeek الان در تاریخچه‌ی مخزن مشترک است و **هر کسی که به ریپو
+دسترسی دارد می‌تواند آن‌ها را ببیند** (`.env` کامیت نشده، ولی این پیش‌فرض‌ها عملاً همان لو رفتن راز است).
+
+اقدامات توصیه‌شده (هنوز انجام نشده — نیاز به تصمیم مالک توکن‌ها):
+
+1. **توکن بات بله را از @BotFather بله باطل و دوباره بسازید** و کلید DeepSeek را rotate کنید.
+2. مقادیر پیش‌فرض را از compose حذف کنید و به‌جای `${VAR:-secret}` از `${VAR:?set VAR}` استفاده کنید
+   (مثل `TRAEFIK_ACME_EMAIL` در compose پروडاکشن) و مقادیر واقعی فقط در `.env` محلی/سرور بمانند.
+3. فایل `bot/.env` را از روی `bot/.env.example` بسازید (نمونه در همان پوشه هست).
+
+## ۵. نحوه‌ی استفاده
+
+### ۵.۱ اجرای کامل استک (شامل بات) — روی هر ماشین
+
+```powershell
+git clone https://git.bennu-api-bahrestan.ir/ali_mohaghegh/ERP.git
+cd ERP
+git checkout prod-v7
+
+# ۱) متغیرهای محیطی بات را بسازید (بدون این، بات توکن ندارد):
+copy bot\.env.example bot\.env      # و مقادیر واقعی را داخلش بگذارید
+#    BALE_BOT_TOKEN=...        توکن بات از بله
+#    AI_API_KEY=...            کلید سرویس LLM
+#    BALE_ADMIN_CHAT_IDS=...   چت‌آیدی مدیران
+
+# ۲) کل استک + بات:
+docker compose up -d --build
+```
+
+سرویس `bot` (کانتینر `procurement-bot`) به‌صورت long-polling به `tapi.bale.ai` وصل می‌شود،
+به `api:8000/api/v1` (همان ERP) و پایگاه‌داده‌ی `procurement` وصل است و
+draft های گفتگو را در جدول `bot_drafts` می‌نویسد.
+
+### ۵.۲ اجرای فقط بات (وقتی استک از قبل بالا است)
+
+```powershell
+docker compose build bot
+docker compose up -d bot
+docker compose logs -f bot
+```
+
+### ۵.۳ جریان کاری کاربر نهایی (بات ↔ ERP)
+
+1. کاربر در بله به بات پیام می‌دهد (متن یا وویس — وویس با STT به متن تبدیل می‌شود).
+2. بات با NLU موجودی/تأمین‌کننده/کالا را استخراج می‌کند و یک **draft** می‌سازد
+   (وضعیت `active` در جدول `bot_drafts`) و کارت پیش‌نمایش با فیلدهای خالی می‌فرستد.
+3. کاربر با دکمه‌ی ✅ تأیید می‌کند؛ بات draft را به ERP کامیت می‌کند
+   (از طریق REST: `POST /api/v1/drafts/{id}/commit` با توکن سرویس).
+4. ویزارد فرانت‌اند همان draft را از `GET /api/v1/drafts` می‌خواند و پیش‌پر می‌کند —
+   همگام‌سازی دوطرفه با ذخیره‌ی خودکار (debounced) بین مرورگر و بات.
+5. ویرایشِ پاسخِ کاربر به کارت قبلی بات هم پشتیبانی می‌شود (reply-based edit، بدون کارت تکراری).
+
+### ۵.۴ تست سریع سلامت
+
+```powershell
+docker compose ps bot                 # باید Up باشد
+docker compose logs bot | Select-Object -Last 20
+# داخل کانتینر:
+docker compose exec bot python -m tools.smoke_test   # اگر توکن ست باشد
+```
+
+### ۵.۵ مسیرهای مهم
+
+| مسیر | محتوا |
+|---|---|
+| `bot/app/` | کد بات (handlers برای quote/material/supplier/decisions، bale client، NLU، STT، sync) |
+| `bot/Dockerfile` | ایمیج `python:3.13-slim` + ffmpeg (برای وویس) |
+| `bot/docs/SETUP.md` | راه‌اندازی جزئی‌تر ایجنت |
+| `bot/integration/` | طرح ادغام: نمونه سرویس compose + پچ `X-Actor-Id` |
+| `backend/app/routers/drafts.py` | REST drafts (سمت ERP) |
+| `bot/procurement_ai_agent.bundle` و `bot/git_history_backup.zip` | بکاپ تاریخچه‌ی مستقل قبلی ایجنت |
+
+## ۶. نکات باقی‌مانده برای تیم
+
+- **ادغام با برنچ‌های جدید تیم:** فایل‌های بات فقط روی `prod-v7` هستند؛ `prod-v8`/`prod-v9`
+  آن‌ها را ندارند. برای رسیدن به استقرار نهایی، این برنچ باید با کار تیم merge شود.
+- **سرویس bot در `docker-compose.prod.yml` و `docker-compose.coolify.yml` نیست** —
+  برای استقرار سرور باید به overlay پروڈ اضافه شود (یا از همان base compose استفاده شود).
+- نام قدیمی `ai procurement` در برخی مستندات (`bot/docs/SETUP.md`، `bot/integration/`)
+  ممکن است هنوز دیده شود — محتوایی است و عملکردی تحت تأثیر نیست.

+
+## What it can do
+
+| Activity | Example (voice or text) | Committed via |
+|---|---|---|
+| Register a supplier quote | «سازان نو برای پروژه برج آسمان ۵۰۰ کیلو میلگرد A3 سایز ۱۴، هر کیلو ۴۵ تومن، پرداخت ۳ فاز» | `POST /quotes` |
+| Add a supplier | «تأمین‌کننده جدید پروفیل بر، دسته لوله و اتصالات، تلفن ۰۹۱۲…» | `POST /suppliers` |
+| Add a material | «کالای جدید میلگرد A3 سایز ۱۸ با واحد کیلوگرم» | `POST /materials` |
+| Status queries | «استعلام‌های در انتظار؟» / «کدام‌ها به‌زودی منقضی می‌شوند؟» | `GET /quotes?…` |
+| Accept a quote | «استعلام سازان نو را قبول کن» | `PATCH /quotes/{id}/accept` |
+| Announce a delivery | «اقلام سازان نو رسید، ۵۰۰ و ۲۰۰» | `PATCH /quotes/{id}/arrive-items` |
+
+### The draft → approve loop
+
+1. Send a message or voice note. Voice → ffmpeg → STT; text/STT text → LLM
+   extracts a typed **intent + entities** (JSON mode, Persian digits
+   normalized).
+2. Names are fuzzy-matched against the ERP. Several candidates → inline
+   **pick buttons**; no match → listed as missing.
+3. The bot replies with a **review card**: everything captured + a
+   ✅/⚠️/❌ list of what is still empty.
+4. Keep chatting to refine («قیمت میلگرد ۴۷ شد») — the open draft updates and
+   re-renders. Drafts survive bot restarts (postgres-backed, TTL-swept).
+5. **Nothing is written to the ERP until you tap ✅.** After commit you get the
+   created quote id and the fields left empty.
+
+### Team access & attribution
+
+Each member links their Bale chat once: `/start` → Casdoor username → password
+(validated via the ERP's real `POST /auth/login`, used once, never stored).
+Every mutating call carries `X-Actor-Id: <users.id>` so `quote_events.actor`
+records the **human** who asked.
+
+Commands: `/start` · `/help` · `/drafts` · `/cancel` · `/whoami` · `/unlink`
+
+## Quick start (Docker)
+
+```bash
+cp .env.example .env          # fill PROCUREMENT_BOT_BOT_TOKEN + AI_API_KEY
+docker build -t procurement-ai-agent .
+docker run -d --name procurement-bot --env-file .env \
+  --add-host host.docker.internal:host-gateway \
+  procurement-ai-agent
+docker logs -f procurement-bot
+```
+
+Or as part of the ERP stack — see [`integration/`](integration/README.md)
+(compose service + the one tiny ERP-side patch).
+
+Full setup, env-var reference, flows and troubleshooting:
+**[docs/SETUP.md](docs/SETUP.md)**.

+
+Design notes:
+
+- **Telegram-compatible Bale API** (`tapi.bale.ai`): getUpdates long polling —
+  no public port, no webhook, resumable offset persisted across restarts.
+- **Draft-first**: `bot_drafts.payload` holds a talking-friendly JSON that is
+  converted into the exact `POST /quotes` request body (temp_id
+  cross-references) only on approval; the API deliberately tolerates
+  incomplete quotes, so partial commits are explicit, never accidental.
+- **Accept flow echoes the termsheet's existing `schedule_steps`** back to
+  `PATCH /quotes/{id}/accept` (the API replaces steps with what it receives).
+- **Persian-aware matching**: Persian/Arabic digit normalization, ZWNJ folding,
+  Arabic ya/ka folding, difflib ranking on top of the API's ilike search.
+- **Voice notes** arrive as OGG/Opus; ffmpeg converts to mono 16 kHz MP3 before
+  STT. The LLM provider and the STT provider are configured independently
+  (e.g. DeepSeek for NLU + any whisper-compatible endpoint for voice).
+
+## Testing
+
+An offline end-to-end harness stubs Bale/ERP/AI and drives the real handler
+pipeline with fake updates — no token, DB or API key needed:
+
+```bash
+pip install -r requirements.txt
+python tools/smoke_test.py     # → ALL PASSED: 48 passed
+```
