-# - In rootless Podman:    "0 1000 1" (root maps to host user 1000)

+**Status:** ✅ Implemented | Extensible notification system with Discord, ntfy, and Pushover support
 
 ## Overview
 Sends notifications for audiobook request events (pending approval, approved, available, error) to configured backends. Non-blocking, atomic per-backend failure handling. Proper notification timing for all request flows including interactive search.
 
 ## Key Details
-- **Backends:** Discord (webhooks), Pushover (API)
-- **Events:** request_pending_approval, request_approved, request_available, request_error
-- **Encryption:** AES-256-GCM for sensitive config (webhook URLs, API keys)
+- **Backends:** Apprise (API), Discord (webhooks), ntfy (API), Pushover (API)
+- **Events:** request_pending_approval, request_approved, request_available, request_error, issue_reported
+- **Encryption:** AES-256-GCM for sensitive config (webhook URLs, API keys, notification URLs)
 - **Delivery:** Async via Bull job queue (priority 5)
 - **Failure Handling:** Non-blocking, Promise.allSettled (one backend fails, others succeed)

+**Provider Pattern:** `INotificationProvider` interface + registry (matches `IAuthProvider` pattern)

+```
+src/lib/services/notification/
+  INotificationProvider.ts          # Interface + shared types
+  notification.service.ts           # Core service with registry
+  index.ts                          # Re-exports

+    ntfy.provider.ts                # ntfy API
+    pushover.provider.ts            # Pushover API
+```
+
+**Registry:** Module-level `Map<string, INotificationProvider>` with `registerProvider()` / `getProvider()`
+
+**INotificationProvider interface:**
+- `type: string` — provider identifier (registry key)
+- `sensitiveFields: string[]` — fields needing encryption/masking
+- `metadata: ProviderMetadata` — self-describing UI/validation metadata
+- `send(config, payload): Promise<void>` — receives decrypted config
+
+**ProviderMetadata:** `{ type, displayName, description, iconLabel, iconColor, configFields[] }`
+**ProviderConfigField:** `{ name, label, type, required, placeholder?, defaultValue?, options? }`
+
+**Helper functions (notification.service.ts):**
+- `getRegisteredProviderTypes(): string[]` — all registered type keys
+- `getAllProviderMetadata(): ProviderMetadata[]` — metadata for all providers
+
+**Helper functions (notification-events.ts):**
+- `getEventMeta(event)` — raw event metadata (label, title, emoji, severity, priority)
+- `getEventTitle(event, requestType?)` — resolved title (checks `titleByRequestType` first, falls back to `title`)
+- `getEventLabel(event)` — human-readable label for UI
+
+**API Endpoint:** `GET /api/admin/notifications/providers` — returns all provider metadata (admin-only)
 
 ## Extensibility
 
-**Adding New Backend (e.g., Email):**
-1. Add 'email' to NotificationBackendType enum
-2. Create EmailConfig interface
-3. Add encryption logic for smtpPassword
-4. Implement sendEmail() method in NotificationService
-5. Add email card to type selector (green "E" badge)
-6. Add email form fields to modal
+**Adding New Backend (2 steps):**
+1. Create `providers/email.provider.ts` implementing `INotificationProvider`:
+   - Set `type = 'email'`, `sensitiveFields = ['smtpPassword']`
+   - Set `metadata` with displayName, description, iconLabel, iconColor, configFields
+   - Implement `send()` with email-specific logic
+2. Register in `notification.service.ts`: `registerProvider(new EmailProvider())` + re-export from `index.ts`
+
+No UI changes, no API route changes, no Zod schema changes needed — the UI renders dynamically from provider metadata.
 
 **Adding New Event (e.g., download_complete):**
-1. Add 'download_complete' to NotificationEvent enum
-2. Add to event labels in UI
-3. Add trigger point in processor
-4. Add message formatting in Discord/Pushover formatters
+1. Add entry to `NOTIFICATION_EVENTS` in `notification-events.ts` (label, title, emoji, severity, priority)
+2. Optionally add `titleByRequestType` for type-specific titles
+3. Add trigger point in processor, passing `requestType` if relevant
+4. Providers auto-resolve titles via `getEventTitle()` — no per-provider changes needed

 # Multi-Download-Client Support
 
-**Status:** ✅ Implemented | Simultaneous qBittorrent + SABnzbd support
+**Status:** ✅ Implemented | qBittorrent, Transmission, SABnzbd, and NZBGet support
 
 ## Overview
-Users can configure both qBittorrent (torrents) and SABnzbd (Usenet) simultaneously. System selects best release across all indexer types regardless of protocol.
+Users can configure one torrent client (qBittorrent or Transmission) and one usenet client (SABnzbd or NZBGet) simultaneously. System selects best release across all indexer types regardless of protocol.
 
-**Constraint:** 1 client per type (torrent/usenet) for now; architecture supports future expansion.
+**Constraint:** 1 client per protocol (torrent/usenet). Users must remove an existing torrent client before adding a different one.
 
 ## Key Details
 
+### Supported Clients
+
+| Client | Protocol | Auth | Categories |
+|--------|----------|------|------------|
+| qBittorrent | torrent | Cookie-based (login endpoint) | Categories |
+| Transmission | torrent | HTTP Basic Auth + CSRF (`X-Transmission-Session-Id`) | Labels |
+| SABnzbd | usenet | API key | Categories |
+| NZBGet | usenet | HTTP Basic Auth (JSON-RPC) | Config-based categories |
+
+### Protocol Map
+**File:** `src/lib/interfaces/download-client.interface.ts`
+
+```typescript
+export const CLIENT_PROTOCOL_MAP: Record<DownloadClientType, ProtocolType> = {
+  qbittorrent: 'torrent',
+  sabnzbd: 'usenet',
+  nzbget: 'usenet',
+  transmission: 'torrent',
+};
+```
+
+Used by manager's `getClientForProtocol()` and UI's protocol-level enforcement.
+
 ### Configuration Structure
 **Key:** `download_clients` (JSON array, replaces legacy flat keys)
 
 ```typescript
 interface DownloadClientConfig {
   id: string;                    // UUID
-  type: 'qbittorrent' | 'sabnzbd';
+  type: 'qbittorrent' | 'sabnzbd' | 'nzbget' | 'transmission';
   name: string;                  // User-friendly name
   enabled: boolean;
   url: string;
-  username?: string;             // qBittorrent only
+  username?: string;             // qBittorrent/Transmission/NZBGet only
   password: string;              // Password or API key
   disableSSLVerify: boolean;
   remotePathMappingEnabled: boolean;
   remotePath?: string;
   localPath?: string;
   category?: string;             // Default: 'readmeabook'
+  customPath?: string;           // Relative sub-path appended to download_dir
 }
 ```
 
+### Transmission Service
+**File:** `src/lib/integrations/transmission.service.ts`
+
+- **RPC endpoint:** `POST /transmission/rpc` (JSON-RPC)
+- **CSRF:** 409 → capture `X-Transmission-Session-Id` header → retry
+- **Auth:** HTTP Basic Auth (optional)
+- **Categories:** Uses `labels` array on `torrent-add`
+- **Download path:** `download-dir` argument on `torrent-add`
+- **Torrent files:** Base64-encoded via `metainfo` field
+- **Status codes:** 0=stopped→paused, 1=check-pending→checking, 2=checking→checking, 3=download-pending→queued, 4=downloading→downloading, 5=seed-pending→seeding, 6=seeding→seeding
+- **Error handling:** `error > 0` → failed status
+- **postProcess():** No-op (same as qBittorrent)
+
+### NZBGet Service
+**File:** `src/lib/integrations/nzbget.service.ts`
+
+- **RPC endpoint:** `POST /jsonrpc` (JSON-RPC with Basic Auth)
+- **Auth:** HTTP Basic Auth (username + password)
+- **Categories:** Config-based (`Category1.Name`, `Category1.DestDir`), managed via `config()` + `saveconfig()`
+- **Adding NZBs:** Downloads NZB content from Prowlarr, base64-encodes, uploads via `append()`
+- **Queue status:** `listgroups(0)` — QUEUED, PAUSED, DOWNLOADING, FETCHING, PP_* (processing states)
+- **History status:** `history(false)` — SUCCESS/*, WARNING/* → completed; FAILURE/*, DELETED/* → failed
+- **Pause/Resume/Delete:** `editqueue()` with GroupPause/GroupResume/GroupDelete/HistoryDelete commands
+- **postProcess():** `editqueue('HistoryDelete')` — archives from visible history (preserves in hidden archive)
+- **IDs:** Integer NZBIDs (stored as strings in RMAB system)
+
+### Per-Client Custom Download Path
+**Field:** `customPath` (optional string, blank = use base `download_dir` as-is)
+
+Allows each download client to download to a different subdirectory under `download_dir`. Useful for separating torrent and usenet downloads.
+
+**Path Resolution (in `createService()`):**
+```
+finalPath = config.customPath ? path.join(downloadDir, config.customPath) : downloadDir
+```
+
+**Example:**
+- `download_dir` = `/downloads`, qBittorrent `customPath` = `torrents` → `/downloads/torrents`
+- `download_dir` = `/downloads`, SABnzbd `customPath` = `usenet` → `/downloads/usenet`
+- `download_dir` = `/downloads`, `customPath` = blank → `/downloads`
+
+**Validation:**
+- Leading/trailing slashes stripped on save
+- Paths containing `..` rejected (frontend + API)
+- Backward-compatible: existing configs without `customPath` default to base `download_dir`
+
+**Resolved path used by:**
+- Service constructors (`defaultSavePath` / `defaultDownloadDir`)
+- Category creation (qBittorrent `ensureCategory`, SABnzbd `ensureCategory`)
+- Torrent/NZB addition (save path / download-dir)
+- Remote path mapping (applied after customPath resolution)
+- Singleton getters (`getQBittorrentService`, `getSABnzbdService`)
+- Retry fallback path construction (`retry-failed-imports.processor.ts`)
+
+**UI:** Modal shows real-time path preview: `Downloads to: /downloads/torrents`
+
 ### Download Client Manager Service
 **File:** `src/lib/services/download-client-manager.service.ts`
 
 **Methods:**
-- `getClientForProtocol(protocol: 'torrent' | 'usenet')` - Get client by protocol
+- `getClientForProtocol(protocol: 'torrent' | 'usenet')` - Get client by protocol (uses `CLIENT_PROTOCOL_MAP`)
 - `hasClientForProtocol(protocol)` - Check if protocol configured
 - `getAllClients()` - List all configs
 - `testConnection(config)` - Test specific config
 - `invalidate()` - Clear cache on config change
 - `getClientServiceForProtocol(protocol)` - Get instantiated service
 
+**Factory Cases:** `qbittorrent` → `QBittorrentService`, `sabnzbd` → `SABnzbdService`, `nzbget` → `NZBGetService`, `transmission` → `TransmissionService`

+   - Adding all 8 missing states to `TorrentState` type union
+   - Adding mappings to both `mapState()` (legacy) and `mapStateToDownloadStatus()` (unified interface)
+   - `forcedUP` → `seeding`/`completed` enables monitor to trigger import
+   - `stoppedDL` → `paused` ensures qBittorrent v5.x compatibility
+
+**16. pausedUP/stoppedUP mapped as paused instead of completed** - RDT-Client (and qBittorrent after ratio limits) transitions directly to `pausedUP`/`stoppedUP` without passing through `uploading`/`stalledUP`. The `*UP` suffix means the download phase is complete and the torrent is on the upload side. Both states were incorrectly mapped to `'paused'`, causing the monitor to re-schedule checks indefinitely instead of triggering file organization. Fixed by:
+   - `pausedUP` → `seeding` (unified) / `completed` (legacy) — triggers completion in monitor
+   - `stoppedUP` → `seeding` (unified) / `completed` (legacy) — same fix for qBittorrent v5.x
+   - `pausedDL`/`stoppedDL` remain `paused` — download phase genuinely paused
+   - Key insight: any `*UP` state is post-download; any `*DL` state is pre-completion

+## NZB Download Proxy
+
+**RMAB proxies NZB files** — SABnzbd does not need network access to Prowlarr.
+
+Prowlarr returns download URLs that point back to itself (proxy URLs like `http://prowlarr:9696/3/download?apikey=...&link=...`).
+RMAB downloads the NZB file content from that URL, then uploads it to SABnzbd via `mode=addfile` (multipart POST).
+This matches qBittorrent's pattern where RMAB downloads `.torrent` files and uploads the binary content.
+
+**Result:** Download clients only need network access to RMAB. No direct Prowlarr connectivity required.
