Perfect! Now I have a comprehensive understanding. Let me create a detailed report of my findings.

## Autocoder+ Backend Architecture Exploration

I've thoroughly analyzed the backend codebase. Here's a comprehensive breakdown of the project creation and WebSocket implementation:

### 1. PROJECT CREATION FLOW

**Database Model** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\models\project.py):
- Project table has: `id`, `name` (unique), `path`, `created_at`, `updated_at`, `spec_version`
- Cascading relationships to Features, Permissions, Infrastructure, and SpecHistory

**Create Project Endpoint** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\routers\projects.py):
```
POST /api/projects
Body: {
  "name": str,
  "path": str
}
```
- Validates path using `validate_project_path()` to prevent path traversal attacks
- Checks for duplicate project names (409 CONFLICT if exists)
- Creates new Project record with initial `spec_version=1`
- Returns ProjectResponse with id, name, path, timestamps, and spec_version

**Path Security** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\path_security.py):
- Blocks dangerous paths (Windows: C:\Windows, C:\Program Files; Unix: /etc, /bin, /root, etc.)
- Prevents path traversal patterns: `../`, `..\`, URL-encoded variants
- Normalizes and validates paths before acceptance

---

### 2. SPEC CREATION & WEBSOCKET

**Spec Management** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\routers\spec.py):
- Tracks spec versions in `SpecHistory` table (project_id, version, content, change_summary, created_at)
- **Update spec endpoint**: `PUT /api/projects/{name}/spec` - increments version, stores new content
- **Get current spec**: `GET /api/projects/{name}/spec` - returns latest version
- **Spec history**: `GET /api/projects/{name}/spec/history` - returns all versions
- **Rollback**: `POST /api/projects/{name}/spec/rollback/{version}` - creates new version copying old content
- **Change analysis**: `POST /api/projects/{name}/spec/analyze-changes` - analyzes which features might be affected by spec changes

**WebSocket Connection** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\routers\websocket.py):

```
Connection: WS /ws/projects/{project_name}
```

**ConnectionManager** handles:
- Per-project connection sets (multiple clients per project)
- Heartbeat loop (sends ping every 30 seconds)
- Auto-cleanup of disconnected clients
- Broadcasting to all connected clients for a project

**Message Types**:
- `heartbeat` - periodic keepalive
- `agent_log` - log output with type (info/error/tool/permission)
- `agent_status` - agent status changes
- `feature_update` - feature modifications
- `permission_request` - new permission requests from agents

**Initial Connection Flow**:
1. Client connects to `/ws/projects/{project_name}`
2. Project existence verified in database
3. Connection accepted and added to manager
4. Client receives `{"type": "connected", "project": name, ...}`
5. Heartbeat starts
6. Client can send `ping` messages (gets `pong` response)

---

### 3. ROUTE REGISTRATION

**Main App** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\main.py):

```python
from .routers import (
    projects_router, websocket_router, agents_router,
    features_router, permissions_router, spec_router,
    infrastructure_router, git_router
)

app.include_router(projects_router)
app.include_router(websocket_router)
# ... etc
```

**Router Organization** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\routers\__init__.py):
- Each router is defined in its own module
- Centrally exported for clean imports
- Prefixes organize endpoints: `/api/projects`, `/ws/projects`

---

### 4. DATA PASSED DURING SPEC CREATION

The system doesn't have a dedicated "spec creation WebSocket" - instead it uses:

**REST Endpoints for spec updates**:
- PUT /api/projects/{name}/spec - client sends new content
- Triggers creation of new SpecHistory record
- WebSocket broadcasting happens for any observers

**Context Available During Spec Updates**:
1. **Project Context**: project_id, name, path
2. **Spec Content**: Full spec text (unlimited size via Text field)
3. **Change Metadata**: change_summary, version number
4. **Feature Relationships**: Can access all features for change analysis

**What Agents See**:
- Current spec version via `GET /api/projects/{name}/spec`
- Full spec history via `GET /api/projects/{name}/spec/history`
- Features affected by changes via `POST /api/projects/{name}/spec/analyze-changes`

---

### 5. IMPORT PROJECT ENDPOINT DESIGN

To add an "import project" feature that registers an existing folder, here's what would be needed:

**Key Considerations**:

1. **Path Validation** - Use existing `validate_project_path()` function
2. **Project Uniqueness** - Check name doesn't exist (duplicate prevention)
3. **Folder Verification** - Check if path exists on filesystem
4. **Associated Data**:
   - Scan for existing features and register them
   - Detect existing permissions/infrastructure if tracked elsewhere
   - Initialize spec_version (could scan for README/spec file)
   - Optionally create initial SpecHistory entry

**Endpoint Structure**:
```
POST /api/projects/import
Body: {
  "name": str,
  "path": str,
  "scan_features": bool = True  # Auto-scan for existing features
}
Response: ProjectResponse (same as create)
```

**Database Flow**:
1. Validate path (use existing validate_project_path)
2. Check Project.name doesn't exist
3. Optionally validate path exists with os.path.exists()
4. Create new Project record
5. Optional: Create initial SpecHistory entry
6. Optional: Scan directory for feature definitions and create Feature records

---

### 6. AGENT CONTEXT & STATE

**Agent Status Tracking** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\routers\agents.py):
- In-memory state: `_agent_states[project_name][agent_id]` = status (stopped/running/paused/stalled/error)
- Tracks: started_at, paused_at, error message, crashed_at
- Dual agent system: Agent A and Agent B per project

**Features Associated with Projects** (C:\Users\MikeSwanson\claude-projects\Autocode-remix\Autocode-fork\backend\app\models\feature.py):
- Each project has multiple features
- Features track: name, description, category, priority, steps
- Status fields: passes, in_progress, stalled, assigned_agent
- Dependencies: depends_on (list of feature IDs), files_modified (list of paths)
