DottaandPaperclip 4a8178e9cf fix(ui): stabilize composer model selection and refine effort slider (#15444)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Task composers let users select an agent, a model, and an effort
level.
> - The model label changes width when users move the effort slider.
> - This movement makes the control harder to use.
> - This pull request keeps the label fixed while the picker is open.
> - A larger slider gives clearer feedback during selection.

## Linked Issues or Issue Description

**What existing behavior does this improve?**
The shared model and effort picker in task composers.

**Current behavior**
The trigger shows each effort change while the picker is open. Different
label lengths move the control. The slider is small.

**Proposed behavior**
The trigger shows “Select model” while any picker view is open. It shows
the selected model and effort after the picker closes. The slider has a
thicker track and a larger thumb with hover and press feedback.

**Reason and benefit**
Users can change effort without moving the trigger. The larger thumb
gives clearer pointer feedback.

## What Changed

- Keep the trigger text fixed while the picker is open.
- Add slider size and feedback tokens.
- Remove the gray input outline and thumb border. Show keyboard focus on
the thumb.
- Keep a thumb focus outline when Windows high contrast suppresses
shadows.
- Keep native keyboard and pointer controls. Respect reduced motion.
- Test open and closed labels on desktop and mobile.

## Verification

- Picker tests: 27 pass. Composer settings and new-task tests: 86 pass.
- UI typecheck and UI build passed before the final CSS-only
high-contrast fix.
- Token gates pass.
- Full typecheck and build stop at installed Runner API type mismatches
outside these files.
- Revised Chromium checks pass for desktop pointer drag, no input
outline during drag, stable open label, keyboard input, and mobile
rendering. The earlier rendered-image check confirmed reduced-motion
behavior.
- The earlier full local suite did not finish. The approved visual
revision passed 113 focused tests. The final high-contrast fix passed 27
picker tests and token gates.
- Chromium high-contrast and reduced-motion verification shows a visible
thumb focus marker and working keyboard input.
- Open the model picker. Change effort. Confirm “Select model” stays
visible. Close the picker. Confirm the selected model and effort appear.

- All CI gates pass on final head
`7a64104e14251a354b06b7916d09d44692557c4f`, including full typecheck,
tests, build, and browser E2E. Greptile: 5/5 with no findings.

## Risks

- Low risk: shared UI only. Native range controls stay in place.
- Browser thumb rendering can differ between engines.

## Model Used

- OpenAI GPT-6 Codex. Code editing, tool use, and test execution. The
runtime does not expose an exact model variant or context window size.

@paperclipai/ui

Published static assets for the Paperclip board UI.

What gets published

The npm package contains the production build under dist/. It does not ship the UI source tree or workspace-only dependencies.

Storybook

Storybook config, stories, and fixtures live under ui/storybook/.

pnpm --filter @paperclipai/ui storybook
pnpm --filter @paperclipai/ui build-storybook

Typical use

Install the package, then serve or copy the built files from node_modules/@paperclipai/ui/dist.

Editor dependency identity

Keep the root and workspace overrides for @codemirror/state, @codemirror/view, and @lezer/common aligned. CodeMirror requires shared extension identity, while Lezer parsers and syntax highlighters require shared NodeProp IDs. Multiple Lezer copies can crash code-block highlighting with tags is not iterable. src/lib/codemirror-single-instance.test.ts checks the installed dependency graph and highlights sample code through the editor's real language dependencies. GitHub Actions owns regeneration of pnpm-lock.yaml.
