Closes: #1502

Description

Adds a ModelSelector to the chat input toolbar so users can pick a model directly from chat instead of going through Settings.

New ModelSelector component (webview-ui/src/components/chat/ModelSelector.tsx), mounted in ChatTextArea next to the existing ModeSelector / ApiConfigSelector.
Resolves the model list per provider: dynamic providers (e.g. OpenRouter) via useRouterModels, static-model providers via getStaticModelsForProvider.
Falls back gracefully for unsupported/retired providers, showing a selectModelUnsupported tooltip that points back to Settings instead of hiding or breaking the control.
Uses Fzf for search once the model list is long enough (SEARCH_THRESHOLD).
Adds selectModel / selectModelUnsupported i18n strings to chat.json for all supported locales.

Test Procedure

Added unit tests in webview-ui/src/components/chat/__tests__/ModelSelector.spec.tsx covering supported/unsupported providers, dynamic vs. static model lists, and search behavior.
Manual testing: open chat, switch between API configurations using different providers (e.g. OpenRouter, Anthropic), confirm the model dropdown lists the correct models, selecting one updates the active configuration, and providers without inline model listing show the fallback tooltip.

Add a model selector to the chat input area, letting users pick a model directly from chat instead of going through settings. Adds i18n translations for the selector across all supported locales. Co-Authored-By: JunyongParkDev <shewco3@gmail.com> Signed-off-by: daewoongoh <dw.oh@samsung.com> Signed-off-by: JunyongParkDev <jun94.park@samsung.com>

Add tests covering router-model fetch args, tooltip content, search matching by displayName, and search-threshold boundaries; mark a few genuinely equivalent branches with narrow Stryker exclusions.

Add rerender-based tests for stale-memoization scenarios (model list changes, selection changes, config name changes) and a search test that distinguishes a raw id from a self-duplicated id string.

Restructure handleEditClick's useCallback so the deps-array disable comment sits directly above the array on its own line, matching the pattern already used for handleSelect; the previous placement (right before the callback's closing brace) wasn't recognized by Stryker's comment-attachment logic.

The new ModelSelector button adds a tab stop, so the focus test's 10-press budget no longer reaches the textarea (it now needs an 11th). Bump it to 15 for headroom and regenerate the resting/focus screenshots to include the new model selector button.

The new ModelSelector button in the chat toolbar shows up in the sidebar screenshot captured by the real VS Code Extension Host visual test; regenerate the chat-dark baseline to match.

Update electron-chat-dark-sidebar.png with the authoritative snapshot generated by the pinned CI/Xvfb runner to resolve the font rendering mismatch.

📝 Summary

Summary by CodeRabbit

New Features
- Added a model selector to the chat composer.
- Browse, search, and select available models with provider-aware filtering.
- Model selection updates the active chat configuration and resets incompatible options.
- View loading, unavailable, and unsupported-provider states, with a shortcut to settings when needed.
- Model selection respects configured access restrictions and disabled states.
Localization
- Added translated model-selection, loading, and clear-search labels across supported languages.
Tests
- Expanded coverage for model display, searching, filtering, keyboard interaction, and accessibility behavior.

Walkthrough

The chat composer now includes a provider-aware model selector. It supports static and dynamic models, search, organization filtering, unsupported-provider settings fallback, configuration updates, tests, and translations across supported locales.

Changes

Inline model selection

Layer / File(s)	Summary
Model selector behavior `webview-ui/src/components/chat/ModelSelector.tsx`, `webview-ui/src/components/chat/selectorConstants.ts`, `webview-ui/src/components/chat/ModeSelector.tsx`	Adds provider-aware model loading, retired-provider fallback, organization filtering, fuzzy search, selection updates, loading states, unsupported-provider handling, and shared search-threshold configuration.
Chat composer integration `webview-ui/src/components/chat/ChatTextArea.tsx`	Places `ModelSelector` after `ApiConfigSelector` and passes API configuration, organization allow-list, styling, title, and disabled state. Model changes post `upsertApiConfiguration`.
Selector and composer validation `webview-ui/src/components/chat/__tests__/*`	Adds coverage for model sources, loading, selection updates, search, filtering, unsupported providers, configuration propagation, tooltips, disabled states, and focus traversal.
Model selector localization `webview-ui/src/i18n/locales/*/{chat,common}.json`	Adds localized strings for model selection, unsupported providers, loading, and clearing search.

container prop, then assert that the prop is the same document.body instance
returned by the portal lookup. Keep the existing roo-portal lookup assertion and
verify container propagation behavior rather than only the lookup call.

In `@webview-ui/src/components/chat/ModelSelector.tsx`:
- Line 210: Update the ModelSelector display around selectedModelLabel and
provider to use rawProvider when the configured provider is retired, rather than
showing the fallback model ID from useSelectedModel; adjust the retired-provider
test to provide a non-empty selected model ID so it verifies the retired
provider label is preserved.
- Line 173: Update the model button rendered by the model selector to include
aria-pressed={isCurrentModel}, exposing both selected and unselected states to
assistive technology. Extend the relevant model selector test to assert
aria-pressed is true for the selected model and false for an unselected model.

116-117: LGTM!

- Announce selected model to screen readers via aria-pressed - Show the raw configured provider (not a stale model id) as the disabled-view fallback for retired providers, while still preferring an available selected model label - Assert PopoverContent receives the actual roo-portal container in tests, and cover the unset apiProvider fallback path

@coderabbitai review

Mirrors ModelPicker.tsx: hide deprecated models from the chat ModelSelector's picker, but keep the currently selected model visible even if it's deprecated. Addresses edelauna's second-round review on the ModelSelector PR.

…-ui-chat # Conflicts: # apps/vscode-e2e/src/visual/__screenshots__/electron-chat-dark-sidebar.png

The checked-in baseline still reflected the pre-ModelSelector toolbar after merging main's context-token masking change, so CI's Visual Regression job failed on the toolbar region. Refreshed from the actual screenshot captured by the extension-host-visual CI run.

In `@webview-ui/src/components/chat/__tests__/ModelSelector.spec.tsx`:
- Around line 732-756: The ModelSelector tests currently cover search reset only
after selecting a model, not when the popover closes without selection. Add a
test that opens the popover, enters a non-empty search query, closes it via the
model-selector trigger, reopens it, and verifies the search input is empty,
exercising the handleOpenChange(false) path.

In `@webview-ui/src/components/chat/ModelSelector.tsx`:
- Line 283: Update the no-results message element in ModelSelector to include
role="status", preserving its existing styling and translated text so dynamic
search-result changes are announced to assistive technology.
- Line 266: Update the search input styling in ModelSelector by removing
focus:outline-0 or replacing it with a visible focus-visible indicator, while
preserving the existing layout and color classes.

- Restore the search input's visible focus indicator by dropping focus:outline-0. - Mark the no-results message as a role="status" live region so screen readers announce search results changing. - Add a test covering search reset when the popover closes without a selection (handleOpenChange(false) path).

test: strengthen ModelSelector mutation test coverage

d0cc90f

Add tests covering router-model fetch args, tooltip content, search matching by displayName, and search-threshold boundaries; mark a few genuinely equivalent branches with narrow Stryker exclusions.

test: cover remaining ModelSelector mutation gaps

4986118

test: update electron chat sidebar baseline for the model selector

c47ea9c

The new ModelSelector button in the chat toolbar shows up in the sidebar screenshot captured by the real VS Code Extension Host visual test; regenerate the chat-dark baseline to match.
