       #### Thread Support

     

       125
       +
       

     

       126
       +
       The bridge supports Slack threads with a simple IRC-friendly syntax:

     

       127
       +
       

     

       128
       +
       - **Slack → IRC**: Thread messages appear with a `@xxxxx` prefix (5-character thread ID)

     

       129
       +
         - First reply in a thread includes a quote: `<user> @xxxxx > original message`

     

       130
       +
         - Subsequent replies: `<user> @xxxxx message text`

     

       131
       +
       - **IRC → Slack**: Reply to a thread by including the thread ID in your message

     

       132
       +
         - Example: `@abc12 this is my reply`

     

       133
       +
         - The bridge removes the `@xxxxx` prefix and sends your message to the correct thread

     

       134
       +
         - Thread IDs are unique per thread and persist across restarts (stored in SQLite)

     

       135
        
       

     

       136
        
       The bridge ignores its own messages and bot messages to prevent loops.

     

       137

       138

       139
       +
       

     

       140
       +
       The bridge consists of several modules:

       152
       +
       - **`src/lib/cachet.ts`** - User profile lookups from Cachet API

     

       153
       +
       

     

       154
       +
       ### Testing

     

       155
       +
       

     

       156
       +
       The project includes comprehensive unit tests covering all core functionality:

     

       157
       +
       

     

       158
       +

       +
       bun test

     

       160
       +
       ```

     

       161
       +
       

     

       162
       +
       Tests cover:

     

       163
       +
       - Message format parsing (IRC ↔ Slack)

     

       164
