Under the `nerd` symbol preset, `status.enabled` and `status.shadowed` are
Nerd Font private-use icons (U+F111 / U+F10C). Those glyphs are drawn two
cells wide, but `visibleWidth` counts them as one: `tui/utils.ts` pins
`ambiguousIsNarrow: true`, and the PUA block is East_Asian_Width=Ambiguous.
With no separator the icon overhangs into the next cell and swallows the
label's first character, so the role chips in the model browser and model
hub render as `efault` / `ision` / `lan` / `ask` / `dvisor` instead of
`default` / `vision` / `plan` / `task` / `advisor`.
The adjacent `status.success` check on the very same line already carries a
leading space and renders correctly, which isolates the missing separator
as the cause rather than the glyph itself.
Role-chip assertions in test/model-hub.test.ts are updated for the new
spacing, and the change is recorded under CHANGELOG `[Unreleased]`.
Constraint: lint
Confidence: high
Scope-risk: low
- Introduced ModelPickerComponent to enable temporary, floating model selection overlays.
- Centralized role management logic using a new resolveRoleAssignments function in the browser.
- Streamlined model hub by removing legacy pick-mode logic and defaulting to fullscreen views.
- Synchronized model picker state with the registry to ensure accurate offline refreshes.
- Added support for home, end, and page navigation in the model browser.
- Restricted the hover background band to mouse interactions, using cursor glyphs and text accents for keyboard selection instead.
- Synchronized focus states between the model hub sidebar and the browser pane.
- Removed redundant "login" labels from locked provider entries.
- Prevented navigation keys from triggering the input-priority grace period, ensuring responsive movement after idle states.
- Limited the input queue-drain delay to Ctrl+C and Escape double-press gestures.
- Integrated performance statistics (TPS/TTFT) into ModelBrowser and ModelHub components with adaptive visibility.
- Decoupled mouse wheel behavior from selection logic to enable smoother viewport panning.
- Improved UI navigation by preventing unwanted wrapping in role indexes and adding viewport snapping logic.
- Added comprehensive test suites to verify performance display rendering and corrected input interaction behavior.
- Implemented model-specific keys and provider wildcards for `retry.fallbackChains` with updated resolution logic.
- Added interactive fallback chain management in the model roles UI, including support for reordering and editing.
- Improved fallback chain specificity rules and added comprehensive validation with startup warnings.
- Fixed mouse interaction alignment and hover state coordinate mapping in the roles view.
- Prevent selected chips from being hidden when the role strip row overflows.
- Implement horizontal scrolling with a leading ellipsis to maintain visibility of the selection and lookahead context.
- Integrated a horizontal separator in the model browser list to distinguish between frequently used or role-assigned models and other available models.
- Removed the "Recent" category from the Model Hub sidebar to streamline navigation.
- Updated related tests to reflect the removal of the Recent category and the new visual list layout.
- Implemented custom role creation within the Model Hub, including a virtual row for direct initiation and name stripping.
- Added quick-switch cycle editing functionality with persistent ordering and live preview of role membership.
- Optimized sidebar scope navigation to mute empty entries and improve keyboard focus stability during search.
- Updated the Model Hub sidebar UI to prioritize Roles and included comprehensive tests for new navigation and management flows.
- Implemented dynamic reordering of model providers in the sidebar to prioritize matches during active searches.
- Refactored model hub registry synchronization to maintain separate state for fixed, unlocked, and locked provider entries.
- Added a dedicated composition step to reassemble sidebar entries based on current search result counts.
- Added test coverage to verify that provider order reverts to alphabetical upon clearing the search query.
- Enable horizontal navigation between the scope sidebar and model list using left and right arrow keys.
- Update UI help strings to reflect the new spatial navigation controls.
- Replaced the legacy model selector with a full-screen Model Hub, introducing mouse support and a fuzzy-searchable browser.
- Integrated comprehensive model management, including role assignment, thinking-level visualization, and manual provider discovery.
- Implemented a cancellable OAuth login flow and integrated it directly into the Model Hub for provider authentication.
- Centralized model logic and migrated existing tests to support the new component architecture.
