Update pkgver in PKGBUILD, version badge in README, and workspace package version in Cargo.toml. Add changelog entry for 0.1.11 reflecting the metadata bump.
- New test suite in `crates/owlen-tui/tests` covering generation orchestration, message variant round‑trip, and background worker status updates.
- Extend `model_picker` to filter models by matching keywords against capabilities as well as provider names.
- Update `state_tests` to assert that suggestion lists are non‑empty instead of checking prefix matches.
- Re‑export `background_worker` from `app::mod.rs` for external consumption.
- Introduce `MockProvider` with configurable models, health status, generation handlers, and error simulation.
- Add common test utilities and integration tests covering provider registration, model aggregation, request routing, error handling, and health refresh.
- Add `MessageState` trait defining UI reaction callbacks for generation lifecycle, model updates, provider status, resize, and tick events.
- Implement `App::handle_message` to route `AppMessage` variants to the provided `MessageState` and determine exit condition.
- Add `handler.rs` module with the trait and dispatch logic; re-export `MessageState` in `app/mod.rs`.
- Extend `ActiveGeneration` with a public `request_id` getter and clean up dead code annotations.
- Implement empty `MessageState` for `ChatApp` to integrate UI handling.
- Add `log` crate dependency for warning messages.
Added `widgets::model_picker` containing the full model picker rendering logic and moved related helper functions there. Updated `ui.rs` to use `render_model_picker` and removed the now‑duplicate model selector implementation. This cleanly separates UI concerns and improves code reuse.
Introduce a `worker` module with `background_worker` that periodically refreshes provider health and emits status updates via the app's message channel. Add `spawn_background_worker` method to `App` for launching the worker as a Tokio task.
Introduce `App` with provider manager, unbounded message channel, and active generation tracking.
Add `AppMessage` enum covering UI events, generation lifecycle (start, chunk, complete, error), model refresh, and provider status updates.
Implement `start_generation` to spawn asynchronous generation tasks, stream results, handle errors, and abort any previous generation.
Expose the new module via `pub mod app` in the crate root.
Introduce `OllamaCloudProvider` that resolves the API key from configuration or the `OLLAMA_CLOUD_API_KEY` environment variable, constructs provider metadata (including timeout as numeric), and maps auth errors to `ProviderStatus::RequiresSetup`. Export the new provider in the `ollama` module. Add shared HTTP error mapping utilities (`map_http_error`, `truncated_body`) and update local provider metadata to store timeout as a number.
Introduce `OllamaLocalProvider` for communicating with a local Ollama daemon, including health checks, model listing, and stream generation. Export the provider in the Ollama module. Extend `OllamaClient` to accept an optional request timeout and apply it to the underlying HTTP client configuration.

- Expose `OllamaClient` handling HTTP communication, health checks, model listing, and streaming generation.
- Implement request building, endpoint handling, and error mapping.
- Parse Ollama tags response and generation stream lines into core types.
- Add shared module re-exports for easy integration with the provider layer.
- Introduce `ProviderManager` for registering providers, routing generate calls, listing models, and refreshing health in parallel.
- Maintain a status cache to expose the last known health of each provider.
- Update `provider` module to re‑export the new manager alongside existing types.
- Introduce `MIN_MESSAGE_CARD_WIDTH` and use it to switch to compact card layout when terminal width is limited.
- Implement `clip_line_to_width` to truncate UI lines based on available width, preventing overflow in model selector and headers.
- Adjust viewport and card width calculations to respect inner area constraints and handle compact cards.
- Update resize handling and rendering logic to use the new width calculations and clipping functionality.
- Rename “PANEL NAVIGATION” to “PANEL FOCUS” and document Ctrl/Alt + 1‑5 panel focus shortcuts.
- Consolidate navigation, scrolling, and layout controls into clearer sections.
- Add “VISIBLE CUES”, “ACCESSIBILITY”, and “LAYOUT CONTROLS” headings with high‑contrast and screen‑reader tips.
- Update editing, sending, and normal‑mode shortcuts, including new Cmd‑P palette and Ctrl/Alt + 5 focus shortcut.
- Extend visual‑mode help with focus shortcuts for Thinking/Agent panels.
- Refine provider/model picker, theme browser, command palette, repo search, and symbol search descriptions.
- Include “TIPS” section highlighting slash commands and focus behavior.
- Implement `focus_panel` to programmatically switch between panels with validation.
- Add key bindings for `Ctrl+1`‑`Ctrl+5` to focus Files, Chat, Code, Thinking, and Input panels respectively.
- Update pane headers to display focus shortcuts alongside panel labels.
- Extend UI hint strings across panels to include the new focus shortcuts.
- Refactor highlight style handling and introduce a dedicated `highlight_style`.
- Adjust default theme colors to use explicit RGB values for better consistency.
Implemented full markdown table support:
- Parse tables with headers, rows, and alignment.
- Render tables as a grid when width permits, falling back to a stacked layout for narrow widths.
- Added helper structs (`ParsedTable`, `TableAlignment`) and functions for splitting rows, parsing alignments, column width constraints, cell alignment, and wrapping.
- Integrated table rendering into `render_markdown_lines`.
- Added unit tests for grid rendering and narrow fallback behavior.
- Introduce new `owlen-markdown` crate that converts Markdown strings to `ratatui::Text` with headings, lists, bold/italic, and inline code.
- Add `render_markdown` config option (default true) and expose it via `app.render_markdown_enabled()`.
- Implement `:markdown [on|off]` command to toggle markdown rendering.
- Update help overlay to document the new markdown toggle.
- Adjust UI rendering to conditionally apply markdown styling based on the markdown flag and code mode.
- Wire the new crate into `owlen-tui` Cargo.toml.
- Set `default_syntax_highlighting` to true in core config.
- Added language‑aware syntax selector (`select_syntax_for_language`) and highlighter builder (`build_highlighter_for_language`) with unit test.
- Integrated new highlight module into `ChatApp`, using `UnicodeSegmentation` for proper grapheme handling.
- Simplified `should_highlight_code` to always return true and removed extended‑color detection logic.
- Reworked code rendering to use `inline_code_spans_from_text` and `wrap_highlight_segments` for accurate line wrapping and styling.
- Cleaned up removed legacy keyword/comment parsing and extended‑color detection code.
- Introduce `message_border_style` to render message borders with a dimmed version of the role color.
- Add `dim_color` and `color_to_rgb` helpers for color manipulation.
- Update role styling to use `theme.mode_command` for system messages.
- Adjust card rendering functions to accept role and apply the new border style.
- Add `seen_meta` set and `push_meta` helper to avoid duplicate entries when building model metadata strings.
- Extend metadata handling to include context length fallback, architecture/family information, embedding length, size formatting, and quantization details.
- Introduce `populate_model_details_cache_from_session` to load model details from the controller, with a fallback to cached details.
- Update `refresh_models` to use the new cache‑population method instead of manually clearing the cache.
- Add robust size calculations with configurable width bounds and height clamping.
- Guard against zero‑size areas and empty model/theme lists.
- Render popups centered with dynamic positioning, preventing negative Y coordinates.
- Introduce multi‑line list items, badges, and metadata display for models.
- Add ellipsis helper for long descriptions and separate title/metadata generation.
- Refactor theme selector to show current theme, built‑in/custom indicators, and a centered footer.
- Update highlight styles and selection handling for both popups.
- Limit popup width to a configurable range (40‑80 characters) and ensure a minimum width of 1.
- Preserve original width when the terminal is narrower than the minimum.
- Clamp the y coordinate to the top of the area to avoid negative positioning.
- Introduce `system_status_message` helper to determine the message shown in the system/status pane.
- Calculate wrapped line count based on available width, clamp visible rows to 1–5, and set the layout constraint dynamically.
- Update `render_system_output` to accept the pre‑computed message, choose color based on error prefix, and render each line individually, defaulting to “Ready” when empty.
- Adjust UI layout to use the new dynamic constraint for the system/status section.
