💭 I'm checking whether the previous fixes were applied correctly—the TeleportOutButton now shows size="icon-xs" instead of size="xs", and the DraftHeroHeadline button has the cursor-pointer class added. Let me verify these changes in the current version. The prior issues with the hero button are confirmed fixed. Now I'm reviewing the remaining changed files across the web app—the command palette bus, chat view components, command palette logic and tests, chat composer, and other related files—to identify any new issues. I need to check how the CommandPalette icon class constants are being used and whether there's a shared Spinner component for the LoaderIcon consistency. The LoaderIcon with spin animation is a standard pattern here, so that's not a concern. I'm wondering whether disabling the TeleportOutButton while wrapping it in a TooltipTrigger could be problematic—disabled buttons might not trigger pointer events in Base UI, which could prevent the tooltip from appearing. I should check how other header controls handle this combination of disabled state and tooltips. I'm running into an issue with the TeleportOutButton where disabled buttons don't trigger hover events in Chrome and Safari, which means the tooltip explaining when teleport is available won't display properly since the tooltip relies on those hover events to show. Let me look at how the Button primitive is implemented and check if there are other examples in the codebase where tooltips are paired with disabled buttons to see if there's an established pattern for handling this. I'm noticing a real problem here — the disabled:pointer-events-none class on the button means that when it's busy, hover events never reach the tooltip trigger, so those helpful explanatory tooltips about when teleport and import are available can't show up. This is a regression since the tooltip content is specifically written for those disabled states. I should check if there's an existing pattern in the codebase for handling tooltips on disabled buttons. Looking at the ThemeEditorPanel component around that section, I'm checking how the lockReason is being handled with a Tooltip and aria-disabled attribute pattern. I'm realizing there's an accessibility issue in TeleportOutButton where using disabled={busy} combined with the pointer-events-none styling prevents the disabled-state tooltip from ever appearing, breaking the pattern we established elsewhere in the codebase where aria-disabled is used instead to preserve tooltip visibility. The fix is to switch to aria-disabled for the sessionBusy and importNeedsCwd cases while keeping the existing click guard, and apply opacity styling similar to ThemeEditorPanel. I'm considering whether to suggest a single-line replacement at line 77 changing disabled={busy} to aria-disabled={busy} with the className adjustment, since a multi-line suggestion would require reproducing the intervening lines. Finishing the suggestion block for the button's aria-disabled and className updates. I'm also scanning the rest of the changes — the ChatComposer's disabled textarea when teleported out is acceptable since it shows a placeholder explanation, though the string comparison for sendDisabledReason is a bit fragile. The CommandPalette additions look fine as data objects, and I'm noting that the DraftHeroHeadline's raw button element with cursor-pointer was flagged before. led render elements specially? I should check the tooltip.tsx file to see how TooltipTrigger handles disabled states. The disabled attribute on line 77 will trigger pointer-events-none from the Button component, which blocks hover states entirely. I need to post a review comment on lines 69–77 (the multi-line section containing the disabled prop) with the start_line set to 69 and line set to 77 since this is a new file where all lines are additions.

1. modify_pr — One finding: the new header control's disabled state suppresses the tooltip that explains why it is unavailable.
