Fix 1 (owner: "lock must not shift"): the settings dialog's scroll-lock no
longer toggles the content column to overflow-hidden (which hid the
scrollbar and shifted everything right). The column KEEPS overflow-y-auto —
scrollbar and widths stay exactly as they are — and while any MenuShell is
open, non-passive wheel + touchmove listeners on the column preventDefault
so it cannot scroll (owner-ruled mechanism: the scrollbar may stay,
scrolling must not happen, nothing may move). Native listeners via ref —
React attaches synthetic wheel/touch passively at the root.
Fix 2 (owner repro: xhigh pin survives a GLM swap on screen until reload):
every models-writing surface now mirrors SERVER TRUTH, never the request
body. The PUT already returns the full stored record with clamps applied —
settings-dialog write() and the composer's save() now setRecord/setModels
from the response, so a swap that rides an unsupported level shows the
clamped value in the same interaction: the row trigger, the open menu's
level list + checkmark, and the composer pill all read the stored record.
Live-verified the owner's exact repro: deepseek pinned extra high → GLM
swap via the slot menu → trigger/menu/pill showed the stored clamped level
immediately; and the lock cycle: scroll 300 → blocked while open → 300
after release, zero positional shift at engage.
