# Phase 8 Task 9: Daemon WebSocket Communication with FMDM Architecture
**Status**: ✅ COMPLETED - All core and sub-tasks finished
**Priority**: 🔥 CRITICAL - Foundation for all future client-server architecture
**Started**: 2025-07-27
**Completed**: 2025-07-28
## Overview
Implement a **unified daemon architecture** that provides both WebSocket-based internal communication (TUI/CLI ↔ Daemon) and REST-based external communication (Claude Desktop ↔ MCP endpoints) in a single process. The daemon maintains the FMDM (Folder MCP Data Model) as the single source of truth and broadcasts updates to all connected clients whenever state changes.
## Unified Daemon Architecture
### **Single Process, Dual Servers Design**
The new daemon runs **two servers simultaneously** in one process:
```
┌─────────────────┐ WebSocket ┌──────────────────┐ REST/HTTP ┌─────────────────┐
│ TUI Clients │◄─────────────────┤ Unified ├─────────────────►│ Claude Desktop │
│ CLI Clients │ Port 31849 │ Daemon │ Port 31850 │ External LLMs │
│ Web Clients │ (FMDM sync) │ Process │ (MCP endpoints)│ │
└─────────────────┘ └──────────────────┘ └─────────────────┘
```
### **Communication Protocols**
1. **WebSocket Server (Port 31849)** - Internal Communication
- **Purpose**: TUI/CLI folder management via FMDM protocol
- **Clients**: First Run Wizard, Main TUI, Add Folder Wizard, CLI commands
- **Protocol**: FMDM WebSocket messages (folder.add, folder.validate, etc.)
2. **REST Server (Port 31850)** - External Communication
- **Purpose**: MCP endpoints for Claude Desktop integration
- **Clients**: Claude Desktop, External LLMs, API consumers
- **Protocol**: Standard REST/HTTP with MCP JSON-RPC
### **Shared Business Logic**
Both servers access the same underlying services:
- **FMDM Service**: Single source of truth state management
- **Configuration Service**: Centralized folder configuration
- **Indexing Service**: Document processing and search indices
- **Validation Service**: Folder path and configuration validation
### **Benefits of Unified Architecture**
1. **Service Management Simplicity**: One process to start/stop/monitor
2. **Resource Efficiency**: Shared memory for indices, caches, file watchers
3. **Data Consistency**: Same data source for internal and external APIs
4. **Synchronization**: TUI changes immediately available to MCP endpoints
## Component Migration Strategy
### **Migration from Direct Configuration Access to FMDM WebSocket**
Currently, TUI components directly access `ConfigurationComponent` and `FolderValidationService`. These must be migrated to use the FMDM WebSocket protocol instead.
### **Primary Migration Targets (Critical)**
#### **1. TUI Entry Point** (`src/interfaces/tui-ink/index.tsx`)
- **Current Usage**: `configComponent.addFolder()`, `configComponent.validate()`
- **Impact**: Main entry point with CLI parameter handling and cascading flow logic
- **Migration**: Replace with FMDM WebSocket client calls
#### **2. App Main Screen** (`src/interfaces/tui-ink/AppFullscreen.tsx`)
- **Current Usage**: `ConfigurationComponent` import for folder management
- **Impact**: Main screen folder display and management interface
- **Migration**: Use FMDM context for folder list display
#### **3. First Run Wizard** (`src/interfaces/tui-ink/components/FirstRunWizard.tsx`)
- **Current Usage**: `ConfigurationComponent` for initial folder setup
- **Impact**: Critical for first-time user experience and onboarding
- **Migration**: Use FMDM WebSocket for folder creation
#### **4. Add Folder Wizard** (`src/interfaces/tui-ink/components/AddFolderWizard.tsx`)
- **Current Usage**: `FolderValidationService` for real-time validation
- **Impact**: Folder addition workflow and user experience
- **Migration**: Use FMDM WebSocket for validation and adding
#### **5. File Picker Component** (`src/interfaces/tui-ink/components/core/FilePickerListItem.tsx`)
- **Current Usage**: `FolderValidationService` for path validation during browsing
- **Impact**: Real-time validation while navigating folder structure
- **Migration**: Use FMDM WebSocket validation endpoint
### **Secondary Migration Targets**
- **Theme/Config Services**: `ConfigurableThemeService.ts`, `ConfigurationThemeProvider.tsx`
- **CLI Commands**: `src/interfaces/cli/commands/config.ts`, `simple-config.ts`
- **Other Components**: Various validation and configuration utilities
### **Migration Pattern**
**Before (Direct Configuration Access):**
```typescript
// Current pattern - direct service calls
const configComponent = container.resolve<ConfigurationComponent>(...);
await configComponent.addFolder(path, model);
const folders = await configComponent.getFolders();
await validationService.validate(path);
```
**After (FMDM WebSocket Communication):**
```typescript
// New pattern - WebSocket-based communication
const { fmdm, addFolder, validateFolder } = useFMDM();
await addFolder(path, model);
const folders = fmdm?.folders || [];
await validateFolder(path);
```
### **TUI Cascading Flow Preservation**
The migration must preserve the existing TUI cascading flow logic:
**Without Parameters:**
```bash
folder-mcp # or npm run tui
```
1. Check if folders are configured via FMDM
2. **If no folders** → First Run Wizard → Create folder via WebSocket → Main TUI
3. **If folders exist** → Main TUI directly
**With Parameters:**
```bash
folder-mcp -d /path/to/folder -m some-model
```
1. **If -d or -m provided** → Add Folder Wizard (pre-populated) → Main TUI
2. All folder operations go through FMDM WebSocket protocol
## Core Architecture Principles
1. **FMDM as Single Source of Truth**: Daemon owns and manages the complete system state
2. **Validation Separation**: Real-time validation via dedicated endpoint before actions
3. **Simple Action Responses**: Actions return only success/failure
4. **State via Broadcasts**: All state updates come through FMDM broadcasts
5. **Client Simplicity**: Clients validate, act, then react to new FMDM
## Implementation Guidelines
### Dependency Injection Requirements
- **All services MUST be registered in DI container**: Register new services in `src/di/setup.ts`
- **No direct imports of services**: Use container resolution, not `new Service()` or `import { service }`
- **Follow existing DI patterns**: Look at current daemon DI setup for consistency
- **Clean dependency graphs**: Services should only depend on abstractions, not concrete implementations
### Module Boundary Requirements
- **Clear separation of concerns**: WebSocket logic separate from business logic separate from data models
- **No circular dependencies**: Services in different layers should have clear dependency direction
- **Shared types in separate modules**: Protocol types, FMDM interfaces should be importable by both daemon and TUI
- **Interface segregation**: Each service should have focused, single-responsibility interfaces
### Human Verification Points
- **End-to-end testing required**: Major integration points require human verification using actual TUI
- **Protocol compliance**: All WebSocket messages must exactly match specification
- **Performance verification**: Multi-client scenarios must be tested with real TUI instances
## WebSocket Protocol Design
### Client → Daemon Messages
#### 1. Connection Initialization
```typescript
{
type: "connection.init",
clientType: "tui" | "cli" | "web"
}
```
#### 2. Folder Validation (Real-time)
```typescript
{
type: "folder.validate",
id: string, // Correlation ID
payload: {
path: string
}
}
```
#### 3. Add Folder
```typescript
{
type: "folder.add",
id: string,
payload: {
path: string,
model: string
}
}
```
#### 4. Remove Folder
```typescript
{
type: "folder.remove",
id: string,
payload: {
path: string
}
}
```
#### 5. Heartbeat
```typescript
{
type: "ping",
id: string
}
```
### Daemon → Client Messages
#### 1. FMDM Update (Broadcast to all clients)
```typescript
{
type: "fmdm.update",
fmdm: {
version: string,
folders: Array<{
path: string,
model: string
}>,
daemon: {
pid: number,
uptime: number
},
connections: {
count: number,
clients: Array<{
id: string,
type: string,
connectedAt: string
}>
},
models: string[]
}
}
```
#### 2. Validation Response
```typescript
{
id: string, // Matches request ID
valid: boolean,
errors: Array<{
type: "not_exists" | "not_directory" | "duplicate" | "subfolder",
message: string
}>,
warnings: Array<{
type: "ancestor",
message: string,
affectedFolders?: string[]
}>
}
```
#### 3. Action Response (Simple)
```typescript
{
id: string, // Matches request ID
success: boolean,
error?: string // Only present if success is false
}
```
#### 4. Heartbeat Response
```typescript
{
type: "pong",
id: string
}
```
## Example Flows
### Flow 1: Adding a Regular Folder
```
1. User navigates to folder in TUI
Client → Daemon: {"type": "folder.validate", "id": "v1", "payload": {"path": "/Users/test"}}
Daemon → Client: {"id": "v1", "valid": true, "errors": [], "warnings": []}
2. User clicks "Add Folder"
Client → Daemon: {"type": "folder.add", "id": "a1", "payload": {"path": "/Users/test", "model": "nomic-embed-text"}}
Daemon → Client: {"id": "a1", "success": true}
3. Daemon updates internal state and broadcasts
Daemon → ALL Clients: {"type": "fmdm.update", "fmdm": {...}}
4. All TUIs update their display based on new FMDM
```
### Flow 2: Adding an Ancestor Folder
```
1. User navigates to /Users/hanan (ancestor of /Users/hanan/Documents)
Client → Daemon: {"type": "folder.validate", "id": "v2", "payload": {"path": "/Users/hanan"}}
Daemon → Client: {
"id": "v2",
"valid": true,
"errors": [],
"warnings": [{
"type": "ancestor",
"message": "This folder is an ancestor of 1 existing folder",
"affectedFolders": ["/Users/hanan/Documents"]
}]
}
2. TUI shows warning but allows action
User clicks "Add Folder" anyway
Client → Daemon: {"type": "folder.add", "id": "a2", "payload": {"path": "/Users/hanan", "model": "nomic-embed-text"}}
Daemon → Client: {"id": "a2", "success": true}
3. Daemon internally:
- Removes /Users/hanan/Documents from config
- Adds /Users/hanan to config
- Updates FMDM
- Broadcasts new state
4. All clients receive updated FMDM showing only /Users/hanan
```
### Flow 3: Validation Error (Blocked)
```
1. User navigates to non-existent folder
Client → Daemon: {"type": "folder.validate", "id": "v3", "payload": {"path": "/does/not/exist"}}
Daemon → Client: {
"id": "v3",
"valid": false,
"errors": [{"type": "not_exists", "message": "Folder does not exist"}],
"warnings": []
}
2. TUI disables "Add Folder" button, shows error
```

# Test error conditions
> {"type": "folder.add", "id": "err1", "payload": {"path": "/does/not/exist", "model": "test"}}
# Expected: {"id": "err1", "success": false, "error": "..."}
```
**Expected Results**:
- Add folder operations update FMDM and broadcast to all clients
- Remove folder operations update FMDM and broadcast to all clients
- Ancestor replacement removes descendant folders automatically
- Error responses include helpful error messages
- All operations maintain FMDM consistency
**🧑💻 HUMAN TESTING REQUIRED**:

{"type": "folder.add", "id": "add-sub", "payload": {"path": "/Users/test/parent/child", "model": "test"}}
// Then add parent folder (should remove child automatically)
{"type": "folder.add", "id": "add-parent", "payload": {"path": "/Users/test/parent", "model": "test"}}
```
- ✅ Verify both operations succeed
- ✅ Verify final FMDM only contains `/Users/test/parent` (child removed)
5. **Test Error Conditions**:
```json
// Try to add non-existent folder
{"type": "folder.add", "id": "err-test", "payload": {"path": "/does/not/exist", "model": "test"}}
```
- ✅ Verify receives: `{"id": "err-test", "success": false, "error": "..."}`
- ✅ Verify error message is helpful and descriptive
**Expected Human Verification Outcomes**:
- All folder operations work as expected
- FMDM broadcasts reach all connected clients
- Error handling is robust and informative
- No daemon crashes or connection issues
- Response times are under 100ms for operations

- [ ] Open second TUI instance and verify both stay synchronized
- [ ] Test connection status indicator works correctly
**🧑💻 COMPREHENSIVE HUMAN TESTING REQUIRED**:
After implementing Sub-Task 9.12, please verify complete TUI migration to WebSocket:
1. **Test Environment Setup**:
```bash
# Terminal 1: Start daemon
npm run build
node test-daemon.js
# Terminal 2: Launch TUI
npm run tui
# Terminal 3: WebSocket monitoring
wscat -c ws://127.0.0.1:31849
```
2. **Test TUI-Daemon Connection**:
- ✅ TUI starts successfully and connects to daemon
- ✅ Connection status indicator shows "Connected"
- ✅ Folder list loads from FMDM (not direct config access)
- ✅ Monitor Terminal 3 receives FMDM updates when TUI connects
3. **Test Add Folder Wizard**:
```bash
# In TUI: Navigate to Add Folder, select a test folder
```
- ✅ File picker shows real-time validation (errors/warnings)
- ✅ Folder validation uses WebSocket (not FolderValidationService)
- ✅ Successfully adding folder updates TUI immediately
- ✅ Monitor Terminal 3 receives FMDM broadcast with new folder
- ✅ No direct ConfigurationComponent calls (check logs)
4. **Test Multi-Client Synchronization**:
```bash
# Terminal 4: Launch second TUI instance
npm run tui
```
- ✅ Both TUI instances show identical folder lists
- ✅ Add folder in TUI #1 → appears immediately in TUI #2
- ✅ Remove folder in TUI #2 → disappears immediately in TUI #1
- ✅ All changes reflect in both instances within 100ms
5. **Test Error Handling & Connection Recovery**:
```bash
# Stop daemon (Ctrl+C in Terminal 1), observe TUI behavior
```
- ✅ TUI shows "Disconnected" status when daemon stops
- ✅ TUI attempts auto-reconnection (retry indicator visible)
- ✅ Restart daemon → TUI reconnects automatically
- ✅ After reconnection, folder list syncs correctly
6. **Test Complete TUI Functionality**:
- ✅ **FirstRunWizard**: Uses FMDM for initial folder setup
- ✅ **AddFolderWizard**: Uses WebSocket validation, not direct service
- ✅ **ManageFolderItem**: Remove operations via WebSocket
- ✅ **Header**: Shows connection status and FMDM stats
- ✅ **AppFullscreen**: Displays folders from FMDM, not config
7. **Verify Architecture Compliance**:
```bash
# Check for any remaining direct config access
grep -r "ConfigurationComponent\|FolderValidationService" src/interfaces/tui-ink/
# Should return minimal or no results
```
- ✅ No direct `ConfigurationComponent` imports in TUI components
- ✅ No `FolderValidationService` imports in TUI components
- ✅ All folder operations go through `FMDMContext`
- ✅ Clean separation between TUI and daemon infrastructure
**Expected Human Verification Outcomes**:
- **Complete Migration**: TUI uses WebSocket exclusively, no direct config access
- **Real-Time Sync**: All TUI instances stay synchronized via FMDM broadcasts
- **Robust Connection Handling**: Auto-reconnection and status indicators work
- **Seamless UX**: User experience is smooth with no noticeable change from old architecture
- **Performance**: No lag, stuttering, or delays in folder operations
- **Architecture Compliance**: Clean module boundaries maintained

const folderPath = '/tmp/concurrent-test';
clients.forEach((ws, i) => {
ws.send(JSON.stringify({
type: 'folder.add',
id: `concurrent-${i}`,
payload: { path: folderPath, model: 'test' }
}));
});
// Verify only one succeeds, others get appropriate errors
let responses = 0;
clients.forEach(ws => {
ws.on('message', (data) => {
const msg = JSON.parse(data.toString());
if (msg.id && msg.id.startsWith('concurrent-')) {
console.log(`Response ${++responses}:`, msg);
}
});
});
}
testConcurrentOperations().catch(console.error);
```
**Run Error Tests**:
```bash
# 1. Start daemon
npm run test:daemon
# 2. Run error tests
node error-test.js
node concurrent-test.js
```
**Expected Results**:
- **Daemon Not Running**: Clear error messages, no crashes
- **Connection Drops**: Graceful failure, auto-reconnection
- **Invalid Messages**: Proper error responses, no daemon crashes
- **Concurrent Operations**: Race conditions handled, consistent state
- **General**: All error scenarios logged appropriately

### Sub-Task 9.16: Migrate TUI Components to FMDM WebSocket ✅ COMPLETED
**Priority**: HIGH
**Estimated Time**: 3 hours
**Components to Migrate**:
- **TUI Entry Point** (`src/interfaces/tui-ink/index.tsx`)
- **App Main Screen** (`src/interfaces/tui-ink/AppFullscreen.tsx`)
- **First Run Wizard** (`src/interfaces/tui-ink/components/FirstRunWizard.tsx`)
- **Add Folder Wizard** (`src/interfaces/tui-ink/components/AddFolderWizard.tsx`)
- **File Picker** (`src/interfaces/tui-ink/components/core/FilePickerListItem.tsx`)
**Migration Pattern**:
```typescript
// Replace direct configuration access
const configComponent = container.resolve<ConfigurationComponent>(...);
await configComponent.addFolder(path, model);
// With FMDM WebSocket communication
const { fmdm, addFolder } = useFMDM();
await addFolder(path, model);
```
**Success Criteria**:
- [ ] All 5 primary components use FMDM WebSocket instead of direct config access
- [ ] TUI cascading flow works exactly as before (no folders → wizard → main)
- [ ] CLI parameters (-d, -m) still trigger add folder wizard correctly
- [ ] Real-time validation performance maintained in file picker
- [ ] No TypeScript compilation errors
**🛑 HUMAN VERIFICATION REQUIRED - FULL TUI EXPERIENCE TEST**:
- [ ] Test TUI without parameters: first run wizard → main screen flow
- [ ] Test TUI with -d parameter: add folder wizard → main screen flow
- [ ] Test TUI with existing folders: direct to main screen
- [ ] Test real-time folder validation during file browsing
- [ ] Test multi-TUI synchronization with folder add/remove operations

### Sub-Task 9.17: Integrate MCP Endpoints into Unified Daemon 🚧 NEXT
**Priority**: HIGH
**Estimated Time**: 2 hours
**Implementation**:
- Move MCP REST endpoints to run inside unified daemon on port 31850
- Connect MCP endpoints to shared business logic (same services as WebSocket)
- Ensure MCP endpoints can access current folder configuration via FMDM
**Files**:
- Update `src/domain/daemon/daemon-service.ts` to start REST server
- Move `src/interfaces/mcp/endpoints.ts` logic into daemon
- Connect MCP endpoints to shared FMDM service
**Success Criteria**:
- [ ] MCP REST endpoints accessible on http://127.0.0.1:31850
- [ ] Claude Desktop can connect and use MCP endpoints
- [ ] MCP endpoints show current folders from FMDM
- [ ] TUI folder changes immediately available to MCP endpoints
- [ ] Single daemon process manages both WebSocket and REST servers
**🛑 HUMAN VERIFICATION REQUIRED - MCP INTEGRATION TEST**:
- [ ] Start unified daemon and verify both ports (31849 WebSocket, 31850 REST)
- [ ] Connect Claude Desktop to MCP endpoints
- [ ] Add folder via TUI, verify it's immediately available to MCP
- [ ] Test MCP search functionality works with TUI-managed folders

### Sub-Task 9.18: Legacy Cleanup and PID Integration
**Priority**: MEDIUM
**Estimated Time**: 1 hour
**Cleanup Tasks**:
- Delete old `src/daemon/index.ts` (simple HTTP-only daemon)
- Update main screen daemon PID detection to use new unified daemon
- Remove any documentation references to old daemon
- Clean up unused imports and references
**Files**:
- Remove `src/daemon/index.ts`
- Update any PID file detection logic
- Update CLI daemon start command to use unified daemon (no -f parameter required)
**Success Criteria**:
- [ ] Old daemon code completely removed
- [ ] Main screen shows correct PID for unified daemon
- [ ] `folder-mcp daemon start` works without folder parameter
- [ ] No broken imports or references to deleted code
- [ ] Documentation only references unified daemon
**🛑 HUMAN VERIFICATION REQUIRED - CLEANUP VERIFICATION**:
- [ ] Confirm old daemon files are deleted and no longer accessible
- [ ] Verify main screen PID detection works with new daemon
- [ ] Test that daemon start command works without parameters
- [ ] Ensure no broken functionality from cleanup
