New /api/lairk-roster reads the whole of chat-clock (cached 2 min) and returns every handle that has spoken there and been mentioned by another handle. lairk now draws only that roster, spread by its size, and the walk notice reads from it instead of the recent messages it happened to load (which missed older mentions). Looks load four at a time, online first. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
