fix(bot): eliminate duplicate review cards caused by sync race and edit fallback

Their three commits (730d0bd, 5a9b543, 387edfb) reached production by push and
auto-deployed. 387edfb expects a users.username column that the live database does
not have, so POST /api/v1/auth/login was returning HTTP 500. Their schema changes
never applied either (projects still has only id, name, description, start_date,
pm_user_id, created_at), so nothing depends on the reverted code.

This commit sets the tree back to exactly a02b3ea — verified with git diff against
it — while keeping history linear: the work itself is preserved on 'pm' at 387edfb.

+# procurement_ai_agent — Bale chatbot for the procurement ERP
+
+A **Bale messenger bot** that turns Persian **chat messages and voice notes**
+into procurement actions in the
+[procurement ERP](https://git.bennu-api-bahrestan.ir/ali_mohaghegh/ERP) —
+draft-first: it captures what it understood, tells you **what it did** and
+**what is still empty**, and **commits only after you approve** with a ✅ button.

+
+## 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
+```

+# Setup & Operations Guide
+
+A Bale messenger bot that turns Persian **chat messages and voice notes** into
+procurement actions in the ERP. It works **draft-first**: it captures what it
+understood, tells you exactly **what it did** and **what is still empty**, and
+**commits only after you approve** with a ✅ button.
+
+Bale's Bot API is a Telegram-compatible clone hosted at `tapi.bale.ai`, so the
+bot uses the familiar `getUpdates` long-polling — **no public port, no webhook,
+no TLS setup**.
+
+---
+
+## What it can do (v1)
+
+| 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` (nested create) |
+| 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 (the core idea)
+
+1. You send a message (or voice note). The bot converts voice to text
+   (STT) and extracts an **intent + entities** (LLM).
+2. Names are fuzzy-matched against the ERP (supplier / material / unit /
+   project). Multiple candidates → inline **pick buttons**; no match → it is
+   listed as missing.
+3. The bot replies with a **review card**: everything it captured, plus a
+   ✅/⚠️/❌ **list of what is still empty** («یادآوری چیزهای خالی»).
+4. You keep chatting to refine («قیمت میلگرد ۴۷ شد», «پروژه برج آسمان») — the
+   open draft is updated and re-rendered.
+5. **Nothing is written to the ERP until you tap ✅ ثبت نهایی.** Partial
+   commits are possible («ثبت فقط اقلام مشخص») because the API deliberately
+   tolerates incomplete quotes. After commit you get the created quote id and
+   the list of fields that were left empty.
+
+### Team access & attribution
+
+- Every user links their Bale chat to their ERP account once: `/start` →
+  Casdoor **username** → **password** (validated through the real
+  `POST /auth/login`; the password is used once and never stored).
+- Mutating API calls carry `X-Actor-Id: <users.id>` so `quote_events.actor`
+  records the **human** who asked, not the bot. (The bot's container talks to
+  the api in-network: `http://api:8000/api/v1`.)
+- `BALE_ADMIN_CHAT_IDS` may list chat ids that bypass linking.
+
+### Commands
+
+`/start` · `/help` · `/drafts` (open drafts) · `/cancel` (abort draft/flow) ·
+`/whoami` · `/unlink`
+
+---
+
+## Setup
+
+1. **Create the bot** in Bale's BotFather and copy the token.
+2. **Configure an AI provider** — any OpenAI-compatible endpoint works for
+   both STT (`POST {base}/audio/transcriptions`, Persian) and the LLM
+   (`POST {base}/chat/completions`, JSON mode). Examples: OpenAI `whisper-1`
+   + `gpt-4o-mini`, or any proxy/provider you already use.
+3. **Compose** (dev):
+
+   ```powershell
+   # env passed at compose level (or a .env next to docker-compose.yml)
+   $env:BALE_BOT_TOKEN = "<token>"
+   $env:AI_BASE_URL    = "https://api.openai.com/v1"
+   $env:AI_API_KEY     = "<key>"
+
+   docker compose up -d --build bot
+   docker compose logs -f bot
+   ```
+
+   For Coolify (`docker-compose.coolify.yml`) set the same variables as
+   service-level env vars; the bot container needs no domain/labels.
+
+### Environment variables (prefix `PROCUREMENT_BOT_`)
+
+| Variable | Default | Purpose |
+|---|---|---|
+| `BOT_TOKEN` | — (required) | token from Bale's BotFather |
+| `BALE_API_BASE` | `https://tapi.bale.ai` | Bot API base (overridable for tests) |
+| `API_BASE_URL` | `http://localhost:8000/api/v1` | ERP api (in Docker: `http://api:8000/api/v1`) |
+| `DATABASE_URL` | same postgres as the api | bot's own tables (`bot_*`) |
+| `AI_BASE_URL` / `AI_API_KEY` | — | OpenAI-compatible STT+LLM provider |
+| `STT_MODEL` / `LLM_MODEL` | `whisper-1` / `gpt-4o-mini` | model names at the provider |
+| `ADMIN_CHAT_IDS` | — | comma-separated Bale chat ids allowed without linking |
+| `SERVICE_TOKEN` | — | optional bearer for the day procurement endpoints enforce auth |
+| `DRAFT_TTL_HOURS` | `24` | drafts older than this are marked expired |
+
+In compose these are fed from `BALE_BOT_TOKEN`, `BALE_API_BASE`, `AI_BASE_URL`,
+`AI_API_KEY`, `AI_STT_MODEL`, `AI_LLM_MODEL`, `BALE_ADMIN_CHAT_IDS`,
+`BALE_SERVICE_TOKEN`.

+```
+
+Design notes:
+
+- **Draft state lives in postgres** (`bot_drafts.payload` JSONB in the shape of
+  the eventual API request), so drafts survive bot restarts; short-lived
+  interactions (linking, quote picking, accept/arrive confirmations) are
+  in-memory with a 30-minute TTL.
+- **Callback grammar** fits Bale's 64-byte `callback_data`:
+  `q:ok:{draft8}` (commit), `pk:{draft8}:{field}:{idx}` (pick candidate),
+  `ac:ts:{i}` (choose payment terms), `ar:full` / `ar:ok` (delivery)…
+- **Persian handling**: Persian/Arabic digits are normalized before parsing;
+  fuzzy matching folds ZWNJ and Arabic ya/ka; all user-facing text is Persian.
+- **Voice notes** arrive as OGG/Opus; ffmpeg converts to mono 16 kHz MP3
+  before hitting the STT endpoint (accepted by essentially all providers).
+- The **accept flow echoes the termsheet's existing `schedule_steps`** back to
+  `PATCH /quotes/{id}/accept` (the API replaces steps with what you send, so
+  the bot must send the current ones).
+
+### Attribution tweak in the api (backward compatible)
+
+`backend/app/utils/security.py::get_actor` now prefers an `X-Actor-Id` header
+over the raw bearer token when attributing `quote_events.actor`. Requests
+without that header behave exactly as before.
+
+---
+
+## Testing
+
+Offline harness (no Bale token, no DB, no AI key — stubs everything and drives
+the real handler pipeline with fake updates):
+
+```powershell
+docker compose run --rm bot python tools/smoke_test.py
+# or, with the requirements installed locally:
+cd bot && python tools/smoke_test.py
+```
+
+Covers: linking, voice→draft, ambiguous-material pick buttons, unit fallback,
+draft refinement, commit payload shape (temp_id cross-references), supplier /
+material commits, status digest, accept payload (steps echoed, per-item price),
+arrival quantities («۵۰۰ و ۲۰۰»), cancel and unknown-intent handling.
+
+## Troubleshooting
+
+| Symptom | Likely cause |
+|---|---|
+| Bot silent | wrong `BALE_BOT_TOKEN`; check `docker compose logs bot` |
+| «پردازش هوشمند تنظیم نشده است» | `AI_BASE_URL` / `AI_API_KEY` missing |
+| Voice → «نتوانستم پیام صوتی را تبدیل کنم» | provider rejected the model name (`STT_MODEL`) or key |
+| «ERP API unreachable» | api container not up / wrong `API_BASE_URL` |
+| Draft disappears | TTL expiry (`DRAFT_TTL_HOURS`) or someone pressed ❌ / `/cancel` |

+# ERP integration pack
+
+The agent is a **standalone container** — it talks to the ERP exclusively over
+HTTP and keeps its own state in its own `bot_*` tables. Integrating it into the
+[ERP stack](https://git.bennu-api-bahrestan.ir/ali_mohaghegh/ERP) needs exactly
+two things:
+
+## 1. Compose service
+
+Add [`erp-compose-service.yml`](erp-compose-service.yml) to the ERP's
+`docker-compose.yml` (and the Coolify variant). The bot long-polls Bale, so it
+needs **no ports, no webhook, no TLS** — it joins the compose `default` network
+and reaches `http://api:8000/api/v1` in-network.
+
+Credentials/env are passed at compose level from a `.env` next to the compose
+file: `BALE_BOT_TOKEN`, `AI_BASE_URL`, `AI_API_KEY`, `AI_LLM_MODEL`
+(see [`../.env.example`](../.env.example) for the full list).
+
+> If your stack is started with multiple `-f` files (e.g. a prod_v2 checkout +
+> port-remap override), keep using the same chain — the `bot` service merges in
+> like any other service and the override's host-port remaps don't affect it.
+
+## 2. Per-user attribution in the API
+
+Apply [`x-actor-id.patch`](x-actor-id.patch) — a ~6-line, fully
+backward-compatible change to `backend/app/utils/security.py`:
+
+- before: `get_actor` returns the raw `Authorization: Bearer …` string and
+  `quote_events.actor` stores the bot's token;
+- after: an `X-Actor-Id: <users.id>` header (sent by the bot for every mutating
+  call, carrying the **linked ERP user's id**) takes precedence, so the audit
+  trail records the human who asked, not the bot.
+
+Requests without the header behave exactly as before.
+
+## What the agent does NOT touch
+
+- No ERP code is imported by the bot (HTTP-only, own postgres tables
+  `bot_links` / `bot_drafts` / `bot_messages` / `bot_meta`, created idempotently
+  at startup with `CREATE TABLE IF NOT EXISTS`).
+- No Alembic migration needed — the bot owns its schema.
+- The ERP's data model stays untouched; committed drafts flow through the
+  ordinary public endpoints (`POST /quotes`, `PATCH /quotes/{id}/accept`,
+  `PATCH /quotes/{id}/arrive-items`, `POST /suppliers`, `POST /materials`).

+Why this exists
+---------------
+File downloads require an ``Authorization: Bearer`` header, but a browser
+cannot attach headers to the requests made by ``<iframe src>`` / ``<img

+fetched the bytes with ``fetch`` and rendered a local ``blob:`` URL, but
+download managers (IDM et al.) hook ``blob:`` URLs, fail to resolve them
+outside the originating document, and hand the browser a 0-byte file under
+a bare UUID name — so the preview broke and a junk download appeared.
+
+Instead we mint a short-lived HMAC token scoped to a single attachment and
+put it in the query string, giving the iframe a *real* URL that also
+carries its own authorization. The token is not a session credential: it
+authorises exactly one (quote_id, kind, attachment_id) triple and expires
