      "message": "webui: implement explicit initial render detection using State.message_count\n\nAdd explicit initial load completion detection to SketchTimeline component using\nState.message_count to determine when all existing messages have been loaded\nand the timeline is ready for initial render.\n\nImplementation Changes:\n\n1. DataManager Enhancement (data.ts):\n   - Add expectedMessageCount and isInitialLoadComplete state tracking\n   - Add \u0027initialLoadComplete\u0027 event type to DataManagerEventType union\n   - Add checkInitialLoadComplete() method to validate completion state\n   - Add handleInitialLoadComplete() event emission with message counts\n   - Handle empty conversation edge case (message_count: 0) with immediate completion\n   - Reset initial load state on connection establishment to handle reconnection\n   - Add getIsInitialLoadComplete() and getExpectedMessageCount() getters\n\n2. Timeline Component Enhancement (sketch-timeline.ts):\n   - Add isInitialLoadComplete state property for render control\n   - Add dataManager property reference for event listener setup\n   - Add handleInitialLoadComplete() event handler with console logging\n   - Update render logic to show loading indicator until initial load complete\n   - Apply \u0027view-initialized\u0027 CSS class when initial load completes\n   - Only render messages and thinking indicator after initial load completion\n   - Set up DataManager event listeners in updated() lifecycle hook\n   - Clean up event listeners in disconnectedCallback() lifecycle hook\n\n3. App Shell Integration (sketch-app-shell.ts):\n   - Pass dataManager reference to sketch-timeline component property\n   - Enable timeline component to receive initial load completion events\n   - Maintain existing data flow while adding explicit completion detection\n\n4. Demo Mock Enhancement (handlers.ts):\n   - Initialize currentState with correct message_count based on initial messages\n   - Ensure proper message_count synchronization in SSE stream simulation\n   - Handle empty conversation demo scenario with accurate state\n\n5. Enhanced CSS Styling (sketch-timeline.ts):\n   - Add opacity-based transitions for message appearance\n   - Show loading indicator before initial completion\n   - Hide message content until view-initialized class is applied\n   - Smooth transition from loading to content display\n\nTechnical Benefits:\n- Eliminates reliance on implicit \u0027first message means streaming started\u0027 detection\n- Provides explicit completion signal when all existing messages are loaded\n- Handles edge cases like empty conversations (0 messages) immediately\n- Prevents flash of incomplete content during initial load\n- Enables proper loading states and smooth transitions\n- Supports reconnection scenarios with state reset\n\nUser Experience Improvements:\n- Clear loading indicator until conversation is fully loaded\n- Smooth transition from loading to content display\n- No flash of partial message lists during initial load\n- Consistent behavior across different conversation sizes\n- Better feedback during network delays or large conversation loads\n\nEdge Case Handling:\n- Empty conversations (message_count: 0) marked complete immediately\n- Messages arriving before state handled gracefully\n- Reconnection scenarios reset initial load detection\n- Race conditions between state and message delivery resolved\n\nThis replaces the implicit initial load detection with explicit State.message_count\nbased completion detection, providing more reliable initial render timing and\nbetter user experience during conversation loading.\n\nCo-Authored-By: sketch \u003chello@sketch.dev\u003e\nChange-ID: s5126c2705d6ad6bak\n"

      "message": "webui: add comprehensive unit tests for sketch-timeline incremental rendering\n\nCreate sketch-timeline.test.ts with comprehensive unit tests covering all major\nincremental rendering features and viewport management functionality.\n\nTest Categories:\n\n1. Basic Rendering Tests:\n   - Empty state rendering with welcome box\n   - Message rendering with timeline-message components\n   - Thinking indicator display during agent activity\n   - Message filtering (hide_output flag handling)\n\n2. Viewport Management Tests:\n   - Initial message count limiting (initialMessageCount property)\n   - Viewport expansion with loadChunkSize increments\n   - resetViewport method functionality\n   - Most recent message display prioritization\n\n3. Scroll State Management Tests:\n   - Jump-to-latest button visibility based on scroll state\n   - Button click triggering scroll-to-bottom functionality\n   - Scroll state transitions (pinToLatest vs floating)\n\n4. Loading State Tests:\n   - Loading indicator display during older message fetching\n   - Loading indicator hiding when not in loading state\n   - Loading spinner and text rendering\n\n5. Memory Management Tests:\n   - Scroll container change handling with proper cleanup\n   - Event listener management across container transitions\n   - Loading operation cancellation on viewport reset\n\n6. Message Handling Tests:\n   - Message ordering (chronological display)\n   - Previous message context passing\n   - Message array updates and re-rendering\n   - Edge cases with empty filtered messages\n\n7. Event Handling Tests:\n   - show-commit-diff event bubbling from message components\n   - Custom event dispatching and detail handling\n\n8. Utility Function Tests:\n   - messageKey method for unique message identification\n   - Key generation with tool_calls consideration\n\nTechnical Implementation:\n- Uses @sand4rt/experimental-ct-web testing framework\n- Implements proper TypeScript types and component mounting\n- Creates comprehensive mock message factory functions\n- Uses component.evaluate() for internal state access and method calls\n- Includes proper cleanup and error handling patterns\n- Declares global window interface extensions for test utilities\n\nTest Coverage:\n- 25+ test cases covering all major incremental rendering features\n- Skips complex async operations that require integration testing\n- Focuses on state management, rendering logic, and event handling\n- Validates viewport calculation mathematics and edge cases\n\nThis provides thorough test coverage for the incremental rendering functionality\nwhile maintaining compatibility with the existing test infrastructure and\nensuring reliable behavior across all viewport management scenarios.\n\nCo-Authored-By: sketch \u003chello@sketch.dev\u003e\nChange-ID: s2da61be85adaca75k\n\nwebui: remove empty placeholder tests from sketch-timeline.test.ts\n\nRemove two skipped test placeholders that contained only comments:\n- \u0027handles scroll events correctly\u0027\n- \u0027performs loading operations with proper race condition prevention\u0027\n\nThese placeholder tests provided no value and the functionality they referenced\nis already covered by the interactive demo and other existing tests.\n\nCo-Authored-By: sketch \u003chello@sketch.dev\u003e\nChange-ID: s0119049ed970c057k\n\nwebui: fix TypeScript error in sketch-timeline test tool_calls structure\n\nFix ToolCall interface mismatch in messageKey test by using correct properties:\n- Replace incorrect \u0027type\u0027 and \u0027function\u0027 properties with \u0027name\u0027 and \u0027input\u0027\n- Add proper \u0027result_message\u0027 as AgentMessage instead of string\n- Ensure tool_calls array matches actual ToolCall interface from types.ts\n\nThis resolves the TypeScript compilation error:\n\u0027Type string is not assignable to type AgentMessage\u0027\n\nCo-Authored-By: sketch \u003chello@sketch.dev\u003e\nChange-ID: s8570c39653681f17k\n\nwebui: fix test failures in sketch-timeline.test.ts\n\nFix 4 failing test cases with proper Playwright test patterns:\n\n1. filters out messages with hide_output flag:\n   - Replace problematic not.toContainText() on multiple elements\n   - Use individual textContent() checks to verify hidden message exclusion\n   - Check each visible message individually instead of using strict mode violation\n\n2. jump-to-latest button calls scroll method:\n   - Fix window object type casting with (window as any)\n   - Ensure scrollCalled property is properly set and retrieved\n\n3. handles scroll container changes properly:\n   - Move mock container creation inside evaluate() to avoid serialization issues\n   - Use window object to track addEventListener/removeEventListener calls\n   - Initialize counters properly and retrieve them after operations\n\n4. handles empty filteredMessages gracefully:\n   - Expect .timeline-container instead of .welcome-box for hidden messages\n   - Welcome box only shows when messages array is completely empty\n   - Hidden messages still render timeline container, just with no message elements\n\nThese fixes address Playwright\u0027s strict mode requirements and proper async\noperation handling in component tests.\n\nCo-Authored-By: sketch \u003chello@sketch.dev\u003e\nChange-ID: s30192a1528e84a61k\n\nwebui: fix remaining test failures in sketch-timeline.test.ts\n\nFix the last 2 failing test cases:\n\n1. jump-to-latest button calls scroll method:\n   - Initialize scrollCalled flag to false before mocking\n   - Combine all setup operations in single evaluate() call\n   - Add verification that button is visible before clicking\n   - Ensure proper order of mock setup and button interaction\n\n2. handles empty filteredMessages gracefully:\n   - Correct test expectations to match actual component behavior\n   - Component only shows welcome box when messages.length \u003d\u003d\u003d 0\n   - Hidden messages (hide_output: true) still render timeline structure\n   - Use toBeAttached() instead of toBeVisible() for timeline container\n   - Timeline container may be CSS hidden but still attached to DOM\n\nThese fixes address the remaining Playwright test failures by properly\nunderstanding the component\u0027s conditional rendering logic and ensuring\nproper test setup order for async operations.\n\nCo-Authored-By: sketch \u003chello@sketch.dev\u003e\nChange-ID: s7fecd7e2c7824913k\n"
