  "about": "Layout rework P3: what the server and its clients report in each mixed-version, two-client and phone scenario, recorded from runs on main. Ids are replaced by labels in first-seen order; PTY labels keep their minting kind (pty@@ = daemon, ptyServe = serve). See tests/e2e/helpers/layout-compat-baseline.ts. Linux only: CI records and compares them; macOS and Windows have no baselines.",
