The new composer model picker closed at odd times. Picking an effort level closed it, but Fast did not. The "Legacy models" row also had a misaligned count, and the composer model button only brightened its text on hover, so it did not look like a button.

Now:

  • The picker stays open until you press Escape or click outside it. Effort, Fast, permissions, and model picks all keep it open, and focus stays in the picker.
  • "Legacy models" is now a plain "Show more" row at the end of the list. It adds the older models in place and becomes "Show less".
  • When the list is expanded, it scrolls inside the popup. Before, it ran under the footer (this also happens on main).
  • The composer model button fills like a button on hover and while open, and no longer shows a hover tooltip.

Proof: vp run check:changed passes, the picker browser test now covers stay-open after a pick, and I checked show more/less, every control, Escape, outside click, and the narrow layout in a dev server.

Walkthrough

The model picker remains open after model, effort, and permission selections. Selecting a model schedules focus on its effort levels. Scheduled composer focus is skipped while the picker is open. The picker trigger styling and legacy-model toggle also change.

Changes: Model picker interactions

Layer / File(s) Summary
Selection and popup lifecycle
apps/web/src/components/chat/ProviderModelPicker.tsx, apps/web/src/components/chat/ComposerModelEffort.tsx, apps/web/src/components/chat/ProviderModelPicker.browser.test.tsx
Docked model selection schedules focus on effort levels. Effort and permission selections no longer close the picker. The context no longer exposes a close callback. The browser test checks effort-level focus and Escape dismissal.
Composer focus guard
apps/web/src/components/ChatView.tsx
Scheduled composer focus is skipped while the model picker is open.
Picker trigger and model list controls
apps/web/src/components/chat/ComposerControlsBar.tsx, apps/web/src/components/chat/ModelPickerContent.tsx
The open trigger uses accent colors. The legacy-model toggle appears after the visible model rows and uses “Show more” or “Show less” labels. The docked picker no longer explicitly fills its parent height on small screens.

Merge Risk: Low · up to fb320

A narrow keyboard-navigation edge case remains after selecting a model without effort levels; restore focus within the picker before merging.

…els in place

- Effort, permissions, and models without effort levels no longer close the
  composer model picker. Escape or an outside press closes it.
- "Legacy models" becomes a trailing "Show more" / "Show less" row.
- The docked list now scrolls inside the popup instead of running under
  the footer.
- The composer model trigger fills on hover and while open.

immakermatty added a commit to Lazurio/t3code that referenced this pull request Oct 31, 2026
Root decision 0210, addendum of 2026-10-22, point 1, and its plain-chat
addendum (HumanAndMachines/Lazurio#648; plan DEV-6676, row 28): the person
sees and hears only what Buddy writes in human words. In Buddy's surface
(lazurioBuddy) only:

- The timeline keeps the messages and what the person acts on; T3's record
  of the work stays out. While a turn runs, or work still runs after it, one
  quiet static line says "Buddy na tom pracuje…" / "Buddy is on it…". A
  failed turn shows one human line, and the thread's error banner says
  "Něco se nepovedlo. Zkuste to prosím znovu." instead of T3's text.
- None of the turn's work shows at the end of the timeline, and Buddy's
  queue holds and counts only the person's own messages, never an agent's
  such as Delegace's wake.
- The composer is a message box ("Napište Buddymu…") whose only choice is
  Hermes's Normal / Fast switch, the one option row 23's AcpT3Selection
  lets through, and Buddy's thread keeps full access, which the server
  guard also holds.
- The surface never shows T3's terminal or right panel, their keys stay the
  browser's, and a link in the conversation opens in a new browser tab.

The terminal and right-panel states are read inside the store selectors, so
the React Compiler keeps ChatView's panel presence values memoized
(chatViewPanelPresence.test.ts guards it, #134).

On v0.1.3 upstream moved the work banners and the queue to the end of the
timeline and removed the composer's task list (pingdotgg#25401). The work items
(childInputNow, goalNow, backgroundWorkNow) are masked on Buddy's surface
with inline conditionals in ChatView's body, where hasThreadNow, ThreadNow
and the scroll button's summary read them, so no plain function wraps a
hook result in render. buddyBackgroundWork is whether backgroundWorkNow
exists. useBuddyQueuedRunCount drops an agent's queued message from the
footer's count, which upstream's getUserQueuedThreadRuns keeps, and
buddyWorkBanners and the task-list seam are gone. useBuddyChatShortcuts
takes upstream's `!backgroundThread` condition (pingdotgg#24847), ChatTerminalDrawers
lost focusRequestId (pingdotgg#25009), the placeholder falls back to
DEFAULT_COMPOSER_PLACEHOLDER, and ReopenClosedViewShortcut stays off on the
slimmer root. Effects carry
justified react-effect-budget suppressions and comments are cut to the
four-line limit.

The error banner asks about the thread's own Environment (ChatBannerLane
passes it), so a thread of another Environment keeps T3's own text.

On v0.1.4: upstream dropped the resting composer's control strip, so Buddy's composer hook only gives the placeholder and hasControls is gone; Buddy's controls still replace T3's in ComposerControlsBar ahead of upstream's controls ownership. Upstream shows an approval on its own row (pingdotgg#26255); Buddy's mask leaves no work rows, so the approval falls to upstream's footer for unmatched approvals, and a browser test shows a pending approval there with Approve and Decline and no work row or quiet line. The link_request card stays off Buddy's surface, where link requests are refused (row 25). useChatShortcuts no longer exports its input type, so the overlay takes it from the hook. The tests follow upstream's props and labels: no activeTurnInProgress or onRollbackCheckpoint, the queue's "1 queued message", background work rows with turn items and "Running …" / "Waiting on …" titles, and a single subagent as a [data-v2-item-type=subagent] row. Effect suppressions use the renamed no-unreasoned-state-sync rule. Row 23's AcpT3Selection, row 25's host appearance and row 7's launcher clearance, which this commit carried on v0.1.3, are back in their rows.

On v0.1.6 useThreadLifecycle returns attentionNow, which is the run's Stop
once it went unanswered (Force stop, pingdotgg#27252) and the child's question
otherwise, and workNow, which is the Stop while it is under way and the
background work otherwise; backgroundWorkNow is gone. The inline mask
hides the child's question, the work and the goal on Buddy's surface,
while an unanswered Stop still shows there, so the person can force it;
the contract test pins every mask line, including that one, and
useThreadLifecycle's return. buddyBackgroundWork is whether workNow
exists. Upstream's provider traits menu content
(renderProviderTraitsMenuContent, pingdotgg#28057 and pingdotgg#28076) is not needed in
ComposerControlsBar, which on Buddy's surface returns BuddyComposerControls
before it. A side chat (pingdotgg#26901) renders ChatView embedded, so the thread
tabs and terminal drawers are off for it as they are on Buddy's surface.

aerohh added a commit to aerohh/t3code that referenced this pull request Nov 1, 2026
Main replaced the composer with an always-two-row box and one control
that picks the model and its effort (pingdotgg#25869, pingdotgg#28057 and the picker fixes
after it). Our chat bar, the next commit, redoes the same box its own
way, so main's version comes out here first.

Taken out, on web:
- the two-row layout with model, effort and send grouped on the right,
  and the permissions name on the new-thread row under the box
- the combined model and effort picker with its speed and permissions
  footer, and the fixes built on it (pingdotgg#28076, pingdotgg#28162, pingdotgg#28307, pingdotgg#26514,
  pingdotgg#26470, pingdotgg#26929, and the web side of pingdotgg#28409)
- the Effort display setting (words or bars)
- hiding Ultrathink from effort pickers (pingdotgg#28044). Web and mobile read one
  shared list, so mobile offers it again too.

Brought back: on desktop, the composer shrinks to one row when you scroll
up the chat, with its "Collapse composer on scroll" setting.

Kept: the server, contract and provider parts of pingdotgg#28409 (ACP
thought_level options marked as reasoning, Grok levels sorted lowest to
highest), the shared reasoning-control helper the settings page uses,
and main's other composer fixes.
