Loading screen reads the client version from project.yaml (root version field) and displays it alongside Protocol.PROTOCOL_VERSION at the bottom of the overlay: "v0.1.35 · protocol 21". Falls back to "?.?.?" if project.yaml is missing or unreadable (e.g. when run from an exported pck where the relative path is unavailable). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
