CLAUDE.md gains the surface beside the keyboard model it shares, and NOTES.md the measurements: the 83px clip with its screenshot, the probe that established a top-layer dialog escapes paint containment from inside a view, the UA stylesheet's 354px, the focus steal a longer retry cannot beat, and the submenu this change pushed off-screen before it pulled it back. The last of those is also a note about scope: the issue was claimed saying the submenu would be measured and filed, and the measurement said fix it.
