+# Feature: Critical Maintenance & Editor Foundation
+
+Branch: `feature/critical-maintenance-and-editor`
+
+---
+
+## Block A — Critical Maintenance (Sprint 1)
+
+### A1 — Dynamic Upload Limits (`/api/config`)
+
+**Backend:**
+- `GET /api/config` returns plan-aware file-size limits and usage summary.
+- Registered as `config_bp` at `/api/config`.
+- Anonymous users receive free-tier limits; authenticated users receive limits according to their plan plus a usage summary.
+
+**Frontend:**
+- `useConfig` hook (`src/hooks/useConfig.ts`) fetches limits from the config endpoint with a fallback to the hardcoded `TOOL_LIMITS_MB`.
+- `HeroUploadZone` and `PdfEditor` consume dynamic limits via `useConfig`.
+
+### A2 — Image Resize Tool
+
+**Frontend page:** `src/components/tools/ImageResize.tsx`  
+**Route:** `/tools/image-resize`  
+**Backend endpoint:** `POST /api/image/resize` (already existed)
+
+Features:
+- Width / height inputs with lock-aspect-ratio toggle.
+- Quality slider (1–100, default 85).
+- Accepts files from the homepage smart-upload handoff (via `fileStore`).
+- i18n keys added for `en`, `ar`, `fr`.
+
+### A3 — SMTP & Forgot / Reset Password
+
+**Config keys** (set via environment variables):
+
+| Variable | Default | Description |
+|---|---|---|
+| `SMTP_HOST` | `""` | SMTP server hostname |
+| `SMTP_PORT` | `587` | SMTP server port |
+| `SMTP_USER` | `""` | SMTP login |
+| `SMTP_PASSWORD` | `""` | SMTP password |
+| `SMTP_FROM` | `"noreply@example.com"` | Sender address |
+| `SMTP_USE_TLS` | `true` | Use STARTTLS |
+| `FRONTEND_URL` | `http://localhost:5173` | Used in reset-email link |
+
+**Endpoints:**
+
+| Method | Path | Rate limit | Description |
+|---|---|---|---|
+| `POST` | `/api/auth/forgot-password` | 5/hour | Sends reset email (always returns 200) |
+| `POST` | `/api/auth/reset-password` | 10/hour | Consumes token, sets new password |
+
+**Database tables added:**
+- `password_reset_tokens` — stores hashed tokens with 1-hour expiry.
+- `file_events` — audit log for file-lifecycle events (see A4).
+
+**Frontend pages:**
+- `/forgot-password` — email form
+- `/reset-password?token=…` — new-password form
+
+### A4 — Celery Beat Cleanup Task
+
+**Task:** `app.tasks.maintenance_tasks.cleanup_expired_files`  
+**Schedule:** Every 30 minutes via Celery Beat (`crontab(minute="*/30")`).  
+**Behaviour:** Scans `UPLOAD_FOLDER` and `OUTPUT_FOLDER` for sub-directories older than `FILE_EXPIRY_SECONDS` (default 1800 s). Deletes them and logs a cleanup event to `file_events`.
+
+**Docker:** A `celery_beat` service was added to `docker-compose.yml`.
+
+---
+
+## Feature Flag
+
+| Variable | Default | Description |
+|---|---|---|
+| `FEATURE_EDITOR` | `false` | Gates Block-B editor features (OCR, Remove BG, PDF Editor). Not used by Block-A features. |
+
+---
+
+## Test Coverage
+
+| File | Tests | Status |
+|---|---|---|
+| `test_config.py` | 3 | ✅ Passed |
+| `test_password_reset.py` | 8 | ✅ Passed |
+| `test_maintenance_tasks.py` | 8 | ✅ Passed |
+| **Full suite** | **158** | **✅ All passed** |

+
+All Block B routes are gated behind `FEATURE_EDITOR=true`. Returns 403 when disabled.
+
+### B1 — OCR (Optical Character Recognition)
+
+**Backend:**
+- Service: `app/services/ocr_service.py` — `ocr_image()`, `ocr_pdf()` using pytesseract
+- Tasks: `app/tasks/ocr_tasks.py` — `ocr_image_task`, `ocr_pdf_task`
+- Route: `app/routes/ocr.py` — Blueprint `ocr_bp` at `/api/ocr`

+| `POST` | `/api/ocr/pdf` | 5/min | Extract text from scanned PDF |
+| `GET` | `/api/ocr/languages` | — | List supported OCR languages |
+
+Supported languages: English (`eng`), Arabic (`ara`), French (`fra`).
+
+**Frontend:** `src/components/tools/OcrTool.tsx` — `/tools/ocr`
+- Mode selector (Image / PDF), language selector, text preview with copy, download.
+
+### B2 — Background Removal
+
+**Backend:**
+- Service: `app/services/removebg_service.py` — `remove_background()` using rembg + onnxruntime
+- Task: `app/tasks/removebg_tasks.py` — `remove_bg_task`

+|---|---|---|---|
+| `POST` | `/api/remove-bg` | 5/min | Remove background (outputs transparent PNG) |
+
+**Frontend:** `src/components/tools/RemoveBackground.tsx` — `/tools/remove-background`
+- Upload image → AI processing → download PNG with transparency.
+
+### B3 — PDF Editor (Text Annotations)
+
+**Backend:**
+- Service: `app/services/pdf_editor_service.py` — `apply_pdf_edits()` using ReportLab overlay + PyPDF2
