Pete here. This is Part 3 of digging through the Muse filesystem after my two previous articles hit #1 on Hacker News last week.

The browser itself is a near-stock Chromium installation but the interesting code really comes from how Meta provisions it, routes its browser traffic, and gives the agent control to do things for you.
