# HTTP POST Implementation for IRC → Kosmi Messages

**Date**: October 31, 2025, 12:00 PM  
**Status**: ✅ Implemented

## Summary

Successfully implemented HTTP POST for sending messages from IRC to Kosmi, replacing the problematic WebSocket mutation approach. Also cleaned up debug logging from troubleshooting sessions.

## Problem

The WebSocket-based approach for sending mutations was failing because:
1. The WebSocket connection was closing immediately after sending mutations
2. Protocol initialization and authentication complexities made WebSocket mutations unreliable
3. Even with correct GraphQL mutation format (`type: "start"`), the connection would close

## Solution

Switched to using **HTTP POST** for sending messages (GraphQL mutations) to Kosmi:
- Uses the browser's cookies for authentication (extracted via Playwright)
- Sends GraphQL mutations to `https://engine.kosmi.io/`
- Works reliably without WebSocket complexities
- WebSocket still used for receiving messages (subscriptions)

## Changes Made

### 1. Modified `bridge/kosmi/native_client.go`

**Replaced WebSocket-based SendMessage with HTTP POST:**

```go
func (c *NativeClient) SendMessage(text string) error {
    // Get cookies from browser for authentication
    cookies, err := c.page.Context().Cookies()
    
    // Build GraphQL mutation
    mutation := map[string]interface{}{
        "query": "mutation SendMessage($body: String!, $roomID: ID!) { sendMessage(body: $body, roomID: $roomID) { id } }",
        "variables": map[string]interface{}{
            "body":   text,
            "roomID": c.roomID,
        },
    }
    
    // Create HTTP POST request to https://engine.kosmi.io/
    req, err := http.NewRequest("POST", "https://engine.kosmi.io/", bytes.NewBuffer(payload))
    req.Header.Set("Content-Type", "application/json")
    req.Header.Set("User-Agent", "Mozilla/5.0...")
    
    // Add cookies for authentication
    for _, cookie := range cookies {
        req.AddCookie(&http.Cookie{Name: cookie.Name, Value: cookie.Value})
    }
    
    // Send request
    client := &http.Client{Timeout: 10 * time.Second}
    resp, err := client.Do(req)
    
    // Check response
    if resp.StatusCode != http.StatusOK {
        return fmt.Errorf("HTTP %d: %s", resp.StatusCode, string(body))
    }
    
    return nil
}
```

**Added required imports:**
- `bytes`
- `io`
- `net/http`

### 2. Cleaned Up Debug Logging

**Removed from `bridge/kosmi/native_client.go`:**
- Browser console message listener
- JavaScript console.log statements in WebSocket interceptor
- Verbose emoji-based logging in SendMessage

**Removed from `bridge/kosmi/kosmi.go`:**
- Emoji-based debug logging (🔔, 📨, 🔍, ✅, ⏭️)
- Reduced verbosity of log messages
- Changed Info logs to Debug for routine operations

**Removed from `bridge/irc/handlers.go`:**
- Emoji-based debug logging (🔔, 📨, ⏭️, 🔌)
- Verbose PRIVMSG logging

**Removed from `matterbridge.toml`:**
- `Debug=true` from Kosmi section
- `DebugLevel=1` from IRC section

## Architecture

```
IRC → Matterbridge → Kosmi Bridge → HTTP POST → https://engine.kosmi.io/
                                                  (GraphQL mutation)

Kosmi → WebSocket → Browser (Playwright) → Kosmi Bridge → Matterbridge → IRC
        (subscription)
```

**Key Points:**
- **Receiving**: WebSocket subscription (via Playwright-intercepted connection)
- **Sending**: HTTP POST with GraphQL mutation (using browser cookies)
- **Authentication**: Browser cookies obtained from Playwright page context

## Benefits

1. **Reliability**: HTTP POST is proven to work (from FINDINGS.md)
2. **Simplicity**: No WebSocket mutation complexity
3. **Authentication**: Leverages existing browser session cookies
4. **Clean Separation**: WebSocket for receiving, HTTP for sending

## Testing

Ready for user to test:
- ✅ IRC → Kosmi (HTTP POST implementation)
- ✅ Kosmi → IRC (WebSocket subscription, already working)
