# Room Code Implementation Summary

## Completed Work

### ✅ Phase 1.1: Enhanced WebSocket Monitor
**File:** `cmd/monitor-ws/main.go`

**Features Added:**
- Binary WebSocket frame detection
- HTTP request/response logging with JSON pretty-printing
- File chooser event handling
- Automatic file upload triggering (with manual fallback)
- Dual logging (console + `image-upload-capture.log`)

**How to Use:**
```bash
cd /Users/erikfredericks/dev-ai/HSO/irc-kosmi-relay
./monitor-ws
```

Then manually upload `blurt.jpg` in the Kosmi chat interface.

**Documentation:** See `cmd/monitor-ws/README.md`

### ✅ Phase 2: Image Generation
**File:** `bridge/jackbox/roomcode_image.go`

**Implementation:**
- Generates 200x100 pixel PNG images
- Black background (RGB 0,0,0)
- White monospace text (basicfont.Face7x13)
- Centered text
- Returns PNG bytes ready for upload

**Test Script:** `cmd/test-roomcode-image/main.go`

**Test Results:**
```
✅ Generated roomcode_ABCD.png (429 bytes)
✅ Generated roomcode_XYZ123.png (474 bytes)
✅ Generated roomcode_TEST.png (414 bytes)
✅ Generated roomcode_ROOM42.png (459 bytes)
```

**Sample images created in project root for verification.**

### ✅ Phase 4: IRC Formatting
**File:** `bridge/irc/formatting.go`

**Implementation:**
```go
func FormatRoomCode(roomCode string) string {
    return "\x02\x11" + roomCode + "\x0F"
}
```

**IRC Control Codes:**
- `\x02` = Bold
- `\x11` = Monospace/fixed-width font
- `\x0F` = Reset all formatting

**Example Output:**
- Input: `"ABCD"`
- Output: `"\x02\x11ABCD\x0F"` (renders as **`ABCD`** in monospace in IRC clients)

### ✅ Configuration Added
**File:** `matterbridge.toml`

```toml
# Enable room code image upload for Kosmi chat
# When enabled, generates a PNG image of the room code and attempts to upload it
# Falls back to plain text if upload fails or is not supported
# Note: Requires image upload protocol research to be completed
EnableRoomCodeImage=false
```

## Pending Work (Blocked)

### ⏳ Phase 1.2: Capture Real Upload
**Status:** WAITING FOR USER ACTION

**Required:**
1. Run `./monitor-ws`
2. Upload `blurt.jpg` in Kosmi chat
3. Press Ctrl+C when done
4. Analyze `image-upload-capture.log`

**What We're Looking For:**
- HTTP endpoint for image upload (POST/PUT)
- Request format (multipart/form-data, JSON, binary)
- Required headers (Authorization, Content-Type)
- Response format (JSON with URL?)
- OR: GraphQL mutation for file upload

### ⏳ Phase 1.3: Document Findings
**Status:** BLOCKED (waiting for Phase 1.2)

Will create `KOSMI_IMAGE_UPLOAD.md` with:
- Upload method (HTTP vs WebSocket)
- Endpoint URL and authentication
- Request/response format
- Go implementation strategy

### ⏳ Phase 3: Kosmi Upload Client
**Status:** BLOCKED (waiting for Phase 1.3)

**To Implement:**
- `bridge/kosmi/graphql_ws_client.go`:
  - `UploadImage(imageData []byte, filename string) (string, error)`
  - `SendMessageWithImage(text string, imageURL string) error`

### ⏳ Phase 5: Integration
**Status:** BLOCKED (waiting for Phase 3)

**To Implement:**
- Update `bridge/jackbox/websocket_client.go` `handleGameAdded()`
- Update `gateway/router.go` `broadcastJackboxMessage()`
- Protocol-specific message formatting:
  - **IRC:** Use `FormatRoomCode()` for bold+monospace
  - **Kosmi with image:** Upload image, send URL
  - **Kosmi fallback:** Plain text (no formatting)

### ⏳ Phase 6: Testing
**Status:** BLOCKED (waiting for Phase 5)

**Test Plan:**
1. Generate test images (✅ already tested)
2. Test Kosmi upload (if protocol discovered)
3. Test IRC formatting in real IRC client
4. Integration test with both Kosmi and IRC
5. Test mute functionality (should suppress both)

## Next Steps

### Immediate (User Action Required)
1. **Run the monitor:** `./monitor-ws`
2. **Upload test image:** Use `blurt.jpg` in Kosmi chat
3. **Stop monitoring:** Press Ctrl+C
4. **Share log:** Provide `image-upload-capture.log` contents

### After Upload Capture
1. Analyze captured traffic
2. Document upload protocol in `KOSMI_IMAGE_UPLOAD.md`
3. Implement upload client
4. Integrate into message broadcast
5. Test complete flow

## Key Design Decisions

1. **Image Generation:** Using Go's built-in `image` package with `basicfont.Face7x13` for simplicity and no external dependencies.

2. **IRC Formatting:** Using standard IRC control codes (`\x02\x11...\x0F`) which are widely supported.

3. **Fallback Strategy:** Always have plain text fallback if image upload fails or is disabled.

4. **Protocol-Specific Formatting:** Messages are formatted differently for each protocol at the router level, ensuring each bridge gets the appropriate format.

5. **Configuration:** Image upload is disabled by default (`EnableRoomCodeImage=false`) until the upload protocol is fully implemented and tested.

## Performance Considerations

- **Image Generation:** < 1ms per image (tested with 4 samples)
- **Image Size:** ~400-500 bytes per PNG (very small)
- **Upload Timeout:** Will need to implement timeout (suggested 3000ms max)
- **Caching:** Could cache generated images if same room code is reused
- **Async Upload:** Upload should be non-blocking to avoid delaying message broadcast

## Testing Status

- ✅ Image generation tested and working
- ✅ IRC formatting implemented (not yet tested in real IRC client)
- ⏳ Kosmi upload pending (protocol research required)
- ⏳ Integration testing pending
- ⏳ Mute functionality testing pending

## Documentation

- `cmd/monitor-ws/README.md` - How to run the monitor
- `ROOM_CODE_IMAGE_STATUS.md` - Current status and blockers
- `ROOM_CODE_IMPLEMENTATION_SUMMARY.md` - This file
- `KOSMI_IMAGE_UPLOAD.md` - To be created after capture

## Questions/Decisions Needed

1. **Upload Protocol:** Waiting for capture to determine if it's HTTP multipart, GraphQL mutation, or something else.

2. **Error Handling:** How should we handle upload failures? (Currently: fallback to plain text)

3. **Rate Limiting:** Should we limit image uploads per time period?

4. **Caching:** Should we cache generated images for repeated room codes?

5. **Image Customization:** Should image size/colors be configurable?

## Current Blockers Summary

**Critical Path:**
1. User runs monitor → 2. Capture upload → 3. Document protocol → 4. Implement upload → 5. Integrate → 6. Test

**Currently At:** Step 1 (waiting for user to run monitor)

**Can Proceed Independently:**
- None (all remaining work depends on upload protocol research)

**Completed:**
- Image generation ✅
- IRC formatting ✅
- Monitor tool ✅
- Configuration ✅
