- Define WireEvent type for WebSocket/SSE wire format - Define BondEvent union type for normalized internal events - Define Block types: TextBlock, ThinkingBlock, ToolBlock, UnknownBlock - Add isActive flag for streaming cursor affordance - Implement normalization layer: - normalizeWireEvent() for WebSocket JSON - normalizeSSEEvent() for named SSE events - normalizeTraceEvent() for replay/demo NDJSON - Implement bondReducer with: - Active block tracking - tool_delta attachment to active tool_call block - tool_execute/tool_result correlation by id field - Graceful handling of unknown block kinds Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Create useBondStream hook with: - EventSource connection management - Status tracking (idle, connecting, live, error) - Pause control with event buffering - Integration with bondReducer for state updates - Create useEventHistory hook for replay buffer: - Stores events for timeline scrubbing - Configurable max history size - getUpTo() for replay state derivation - Handle named SSE events (block_start, text, etc.) - Proper cleanup on disconnect and unmount - Flush buffered events when unpausing Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Implements Timeline component with auto-scroll behavior using Intersection Observer. BlockCard provides active cursor affordance (soft glow + shimmer animation). TextBlock, ThinkingBlock, and ToolBlock render each content type with appropriate styling. Completes fn-4.4 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Implements useReplayState hook for tracking replay position and deriving visible state from event history. ReplayControls component provides scrubber slider, play/pause toggle, live/replay indicator, and jump-to-live button. Includes state caching for smooth scrubbing. Completes fn-4.5 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Implements Inspector component that slides in from right showing selected block details. Includes useSelection hook for managing selection state with Escape key and click-outside support. Copy as JSON button with visual feedback. Completes fn-4.6 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Implements useBondReplayFromFile hook that loads TraceEvents from NDJSON files and plays them with timing-accurate delays. DemoControls component provides play/pause, speed selection (0.5x/1x/2x), and progress indicator. Includes demo-events.ndjson with realistic session. Completes fn-4.7 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Wires all components together in App.tsx with full functionality: - Live SSE streaming mode with connection management - Demo mode with pre-recorded event playback - Replay mode for scrubbing through history - Inspector panel for block details - Keyboard shortcuts (Space, L, J/K, Escape) - Contextual help in sidebar Completes fn-4.8 and entire fn-4 epic Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Add type guards for Block types (isTextBlock, isThinkingBlock, etc.) - Change UnknownBlock.kind to literal "unknown" with originalKind field - Update reducer, BlockCard, Inspector to use type guards - Fix Tailwind v4 border-border utility issue in index.css - Remove unused isPaused variable in DemoControls Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
