09:27:32 +0000 Subject: [PATCH 10/18] fix: implement comprehensive session index bounds checking MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Enhanced set_sessions() method to safely handle empty session lists - Added proper bounds checking for current_session() and current_session_mut() - Improved session navigation with bounds validation in next/previous methods - Added utility methods: has_sessions(), session_count(), remove_session() - Added PartialEq derives to Session and Message structs for testing - Created comprehensive test suite with 9 tests covering all edge cases - Fixed critical bug where current_session_index could cause panics on empty vectors 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude

key to select session in sidebar for intuitive navigation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Added SelectSession action to KeyAction enum for Enter key in session list - Enhanced handle_key_event() to return SelectSession when Enter pressed in SessionList - Created select_current_session() method to focus on chat and reset scroll - Updated directional navigation to use the new selection method - Added comprehensive test coverage for session selection functionality - Improved user experience with more intuitive session navigation workflow Users can now press Enter when a session is highlighted to immediately focus on that session's chat window, making navigation feel more natural and responsive. 🤖 Generated with [Claude

Date: Wed, 18 Jun 2025 10:07:34 +0000 Subject: [PATCH 14/18] feat: implement comprehensive markdown rendering with syntax highlighting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add production-ready markdown rendering system for chat messages with: ## Core Features - Full markdown parsing using pulldown-cmark (headings, code blocks, lists, formatting) - High-quality syntax highlighting with syntect (20+ languages supported) - Professional visual theming with 4 pre-built themes (GitHub Dark, Monokai, Solarized, High Contrast) - Performance optimization with LRU caching and smart memory management - Graceful error handling with fallback to basic formatting ## Architecture - Trait-based design allowing pluggable rendering engines - Comprehensive error boundaries prevent markdown failures from crashing UI - Clean separation between parsing, highlighting, theming, and rendering - Ratatui widget integration with proper text conversion ## Chat Integration - Seamlessly integrated into existing TUI chat interface - Maintains compatibility with vim-style selection mode - Enhanced code blocks with language labels and borders - Real-time markdown rendering for improved developer experience ## Language Support Languages: Rust, Python, JavaScript, TypeScript, Java, Go, C/C++, C#, PHP, Ruby, Swift, Kotlin, Scala, Haskell, SQL, HTML, CSS, JSON, YAML, Docker, and more ## Testing - Comprehensive test suite with 6 integration tests - Error handling verification and multi-language support validation - Performance and caching functionality testing This significantly enhances the chat experience with professional-grade markdown rendering while maintaining the existing TUI functionality. 🤖 Generated with [Claude

2001 From: kyluke <1087345+kyluke@users.noreply.github.com> Date: Wed, 18 Jun 2025 12:51:35 +0000 Subject: [PATCH 17/18] fix: resolve test module naming conflict and add quiet test command MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Renamed tests/integration_test.rs to tests/standalone_integration_test.rs to avoid conflict with integration/ directory - Removed unused module imports that were causing build failures - Added test-quiet command to justfile for minimal test output - All tests now pass successfully in CI pipeline
