**Fixes the '@unknown (unknown)' issue:** - Added fallback username resolution when thread_data['users'] lookup fails - Scans thread tweets to find author info when primary lookup returns 'unknown' - Logs successful fallback resolutions **Added User ID Mapping Key:** - Builds comprehensive user_id → @username mapping from thread data - Appends USER_ID_KEY section to prompts showing all participants - Helps void understand who is who when user IDs appear without handles **Example output:** ``` USER_ID_KEY: 1232326955652931584: @cameron_pfiffer 1188460292998602752: @scholzmx 1950680610282094592: @void_comind ``` This resolves cases where the X API doesn't consistently provide usernames in mention data, using the thread context as a reliable fallback source. 🤖 Generated with Claude Code Co-Authored-By: Claude <noreply@anthropic.com>
