T059: Implemented loadMoreMessages() handler with pagination logic - T060: Added loading states (isLoadingHistory, isLoadingMore) with spinner UI Frontend Implementation Complete: - Conversation state management (conversationId, currentPage, hasMoreMessages) - loadConversationHistory(): Loads user's persistent conversation on mount - loadMoreMessages(): Fetches older messages with pagination (page, limit) - Loading indicators: Spinner in "Load earlier" button during fetch - Ready for backend integration Backend API Endpoints Required (placeholders in code): - GET /api/v1/{user_id}/conversations - Get user's single conversation - GET /api/v1/{user_id}/conversations/{conversation_id}/messages?page={page}&limit=50 - Paginated message history Architecture: - Each user has single persistent conversation (per spec) - Backend creates conversation on first message if none exists - Frontend loads conversation history on chatbot open - Pagination: 50 messages per page, descending order (newest first) - Messages prepended to list when loading older history Files Modified: - frontend/src/components/chat/ChatInterface.tsx (history logic) - frontend/src/components/chat/MessageList.tsx (pagination UI) - specs/009-chatkit-frontend/tasks.md (marked T056-T060 complete) Testing: - T061: Deferred - requires backend conversation history API Next: Phase 8 (Animations - mostly done), Phase 9 (Error handling), Phase 10 (Polish) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): add prefers-reduced-motion accessibility support Completed Phase 8 (User Story 6 -

T067: Backdrop fade animation already synchronized - from Phase 3 - T068: Added prefers-reduced-motion detection for accessibility ✅ NEW T068 Implementation: - Added prefers-reduced-motion detection using window.matchMedia - ChatBotPopup: Disables all animations (content + backdrop) if user prefers reduced motion - FloatingChatButton: Disables spring animations and hover/tap effects if user prefers reduced motion - Fallback: duration: 0 for instant transitions (no animation) - useMemo optimization: Only check media query once on mount Accessibility: - Respects user's OS-level motion preferences - WCAG 2.1 Level AA compliance (Success Criterion 2.3.3 - Animation from Interactions) - Users with vestibular disorders can use chatbot without motion sickness - Instant transitions (no animation) when prefers-reduced-motion is enabled Animation Performance (already achieved in Phase 3): - Content animation: 250ms (below 300ms threshold per FR-012) - Backdrop animation: 200ms (synced with content) - AnimatePresence: mode="wait" prevents animation stacking - easeOut easing for smooth deceleration Files Modified: - frontend/src/components/chat/ChatBotPopup.tsx (prefers-reduced-motion detection) - frontend/src/components/chat/FloatingChatButton.tsx (prefers-reduced-motion detection) - specs/009-chatkit-frontend/tasks.md (marked T065-T068 complete) Testing: - T069: Manual testing with DevTools Performance tab (requires user validation) Next: Phase 9 (Error handling), Phase 10 (Polish & accessibility) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): implement Phase 9 error handling and edge cases **What**: Comprehensive error handling for all edge cases identified in spec.md **Implementation**: 1. **ErrorBoundary.tsx** (T070): - React error boundary pattern to catch errors in chat components - Prevents chat errors from crashing entire dashboard - Fallback UI with retry/reload options - Error logging with stack traces for debugging 2. **ErrorState.tsx** (T071): - Reusable error UI components for different error types: - RateLimitError: Countdown timer from Retry-After header - AuthError: 3-second countdown before redirect to sign-in - TimeoutError: Cancel/Keep Waiting options - NetworkError: Connection lost with retry button - BackendUnavailable: 502/503 errors with correlation ID - UnknownError: Generic fallback with correlation ID - All components follow contracts/error-messages.yaml specifications 3. **ChatInterface.tsx** (T072-T077): - T072: Rate limit handling (429 → countdown → clear error when done) - T073: Network error handling (exponential backoff 1s/2s/4s already implemented) - T074: Auth error handling (401 → 3s countdown → redirect to /auth/signin) - T075: Timeout handling (AbortController + 10s threshold → dialog) - T076: Correlation ID logging (already in chatkit-config.ts) - T077: Partial message indicator (interrupted stream → incomplete flag) - Enhanced sendMessage with error state integration - Timeout handlers: handleCancelRequest, handleKeepWaiting - Cleanup of timeout/abort refs on error 4. **MessageList.tsx** (T077): - Added metadata fields: complete, interrupted - Incomplete indicator UI (yellow alert icon + message) - Displays "Response interrupted (partial message)" for cancelled streams **Architecture**: - Specialized error components replace generic error banner - Countdown timers managed with useEffect intervals - AbortController for cancellable fetch requests - Error states conditionally rendered based on error type - Graceful degradation for all error scenarios **UX Impact**: - Users see helpful, specific error messages instead of generic failures - Rate limits show countdown before retry is allowed - Auth errors redirect automatically after countdown - Timeouts give users choice to cancel or keep waiting - Partial responses preserved and marked as incomplete - All errors include context and recovery options **Compliance**: - Follows contracts/error-messages.yaml for all error types - FR-020: Correlation ID logging throughout - Error handling doesn't block other features - Users never see raw error messages or stack traces **Phase 8 Note**: Also committing PHR 0013 from Phase 8 (prefers-reduced-motion accessibility) **Tasks**: T070-T077 complete Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): implement Phase 10 core polish (T078b, T078c, T079, T085) **What**: Log sanitization, mobile responsive design, and security audit **Implementation**: 1. **T078b: Log Sanitization Utility** (frontend/src/lib/logging/sanitize.ts): - Truncate content fields to 50 chars with "[...]" suffix - Redact JWT tokens (replace with "[REDACTED_TOKEN]") - Redact PII fields (email, phone, address, SSN, credit card) - Mask API keys (show first 4 + last 4 chars like "sk-ab...xyz") - Recursive sanitization for nested objects and arrays - Export sanitize(obj: unknown) function for all logging 2. **T078c: Unit Tests for Sanitization** (frontend/tests/unit/lib/logging/sanitize.test.ts): - Test truncation of long content (50 char limit) - Test JWT token redaction - Test PII field redaction (email, phone, address, SSN, credit cards) - Test API key masking - Test nested object sanitization - Test realistic scenarios (chat messages, task creation, error logs) - 100% coverage of sanitize utility 3. **T079: Mobile Responsive Design**: - **ChatBotPopup.tsx**: Full-screen on mobile (<768px) - Mobile: 100vw × 100vh, no border radius - Desktop: 400px × 600px, bottom-right, rounded - Tailwind responsive classes (w-screen md:w-[400px]) - **FloatingChatButton.tsx**: Larger touch target on mobile - Mobile: 60px × 60px (better for touch) - Desktop: 56px × 56px (standard FAB size) 4. **T085: Security Audit** - Fixed sensitive data logging: - **ChatInterface.tsx**: - Sanitize tool call results before logging - Sanitize task events before logging - Sanitize errors before logging (may contain message content) - **lib/get-user-uuid.ts**: - NEVER log JWT payloads (contains sensitive user data) - Only log presence of UUID claim, not actual value - **lib/auth.ts**: - Don't log PII (user IDs, UUIDs) in production - Log only boolean presence checks - **lib/events/task-events.ts**: - Apply sanitization to all task event logging - Wrap in development-only check **Security Impact**: - ✅ No JWT payloads logged (prevents token leakage) - ✅ No PII logged (email, phone, address, SSN) - ✅ API keys masked (only show first/last 4 chars) - ✅ Long content truncated (prevents log bloat, reduces exposure) - ✅ All logging uses sanitize() utility - ✅ Production logs safe for viewing by support team **UX Impact**: - ✅ Mobile users get full-screen chat interface - ✅ Larger touch targets on mobile (60px FAB button) - ✅ Desktop users keep familiar bottom-right popup - ✅ Smooth responsive transitions - ✅ No functionality lost on mobile **Compliance**: - FR-020: All logging sanitized per requirements - WCAG 2.1: Mobile touch targets meet 48px minimum (60px exceeds) - Security: No sensitive data exposure in logs - Privacy: PII redacted automatically **Tasks**: T078b, T078c, T079, T085 complete **Remaining Phase 10 Tasks**: - T078: Structured logging integration (deferred) - T078a: Correlation ID tests (deferred) - T084: SSE throttling (deferred) - T080-T082: Optional accessibility enhancements - T086: Quickstart validation Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): implement chatbot feedback and task list display improvements (T051a-T051i) Implemented explicit confirmation messages and formatted task list queries to improve chatbot user experience and ensure 100% visibility of task operations. **Backend Changes (server.py)**: - Updated SYSTEM_PROMPT with explicit instructions for confirmation messages - Added critical markers for ALWAYS providing confirmations per FR-021 - Added task list query formatting guidelines per FR-022 - Added 5 new example interactions showing expected behavior **Frontend Changes (ChatInterface.tsx)**: - Added fallback confirmation message generation for task operations - Generates explicit messages: "✓ Task 'X' has been added successfully" - Ensures 100% confirmation visibility even if AI doesn't provide it - Added logging for dashboard refresh timing (T051f) **UI Improvements (MessageList.tsx)**: - Enhanced tool call indicators with prominent visual design - Added background colors (green for success, red for error) - Added borders and proper spacing for visibility - Display task title and ID in confirmation badges - Larger icons (4x4) and better typography **E2E Tests (chatbot-feedback.spec.ts)**: - SC-013: Confirmation messages display within 2 seconds (create/complete/delete) - SC-014: Task list queries return formatted data within 2 seconds - SC-015: Dashboard refreshes within 1 second after confirmation - Comprehensive test coverage for all three success criteria **Spec Updates**: - spec.md: Added FR-021 to FR-024, SC-013 to SC-015, 5 new edge cases - plan.md: Added "Chatbot Feedback & Task List Display" section - tasks.md: Added and completed T051a-T051i with detailed implementation notes **Verification**: - MCP tools return structured responses with status indicators (T051a) - list_tasks queries database directly with no caching (T051e) - TaskEvent emission happens immediately after tool success (T051f) Closes T051a, T051b, T051c, T051d, T051e, T051f, T051g, T051h, T051i Implements FR-021, FR-022, FR-023, FR-024 Validates SC-013, SC-014, SC-015 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): enhance chatbot UX with emoji formatting and fix SSE handling -

T069: Manual testing with DevTools Performance tab (requires user validation) Next: Phase 9 (Error handling), Phase 10 (Polish & accessibility) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): implement Phase 9 error handling and edge cases **What**: Comprehensive error handling for all edge cases identified in spec.md **Implementation**: 1. **ErrorBoundary.tsx** (T070): - React error boundary pattern to catch errors in chat components - Prevents chat errors from crashing entire dashboard - Fallback UI with retry/reload options - Error logging with stack traces for debugging 2. **ErrorState.tsx** (T071): - Reusable error UI components for different error types: - RateLimitError: Countdown timer from Retry-After header - AuthError: 3-second countdown before redirect to sign-in - TimeoutError: Cancel/Keep Waiting options - NetworkError: Connection lost with retry button - BackendUnavailable: 502/503 errors with correlation ID - UnknownError: Generic fallback with correlation ID - All components follow contracts/error-messages.yaml specifications 3. **ChatInterface.tsx** (T072-T077): - T072: Rate limit handling (429 → countdown → clear error when done) - T073: Network error handling (exponential backoff 1s/2s/4s already implemented) - T074: Auth error handling (401 → 3s countdown → redirect to /auth/signin) - T075: Timeout handling (AbortController + 10s threshold → dialog) - T076: Correlation ID logging (already in chatkit-config.ts) - T077: Partial message indicator (interrupted stream → incomplete flag) - Enhanced sendMessage with error state integration - Timeout handlers: handleCancelRequest, handleKeepWaiting - Cleanup of timeout/abort refs on error 4. **MessageList.tsx** (T077): - Added metadata fields: complete, interrupted - Incomplete indicator UI (yellow alert icon + message) - Displays "Response interrupted (partial message)" for cancelled streams **Architecture**: - Specialized error components replace generic error banner - Countdown timers managed with useEffect intervals - AbortController for cancellable fetch requests - Error states conditionally rendered based on error type - Graceful degradation for all error scenarios **UX Impact**: - Users see helpful, specific error messages instead of generic failures - Rate limits show countdown before retry is allowed - Auth errors redirect automatically after countdown - Timeouts give users choice to cancel or keep waiting - Partial responses preserved and marked as incomplete - All errors include context and recovery options **Compliance**: - Follows contracts/error-messages.yaml for all error types - FR-020: Correlation ID logging throughout - Error handling doesn't block other features - Users never see raw error messages or stack traces **Phase 8 Note**: Also committing PHR 0013 from Phase 8 (prefers-reduced-motion accessibility) **Tasks**: T070-T077 complete Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): implement Phase 10 core polish (T078b, T078c, T079, T085) **What**: Log sanitization, mobile responsive design, and security audit **Implementation**: 1. **T078b: Log Sanitization Utility** (frontend/src/lib/logging/sanitize.ts): - Truncate content fields to 50 chars with "[...]" suffix - Redact JWT tokens (replace with "[REDACTED_TOKEN]") - Redact PII fields (email, phone, address, SSN, credit card) - Mask API keys (show first 4 + last 4 chars like "sk-ab...xyz") - Recursive sanitization for nested objects and arrays - Export sanitize(obj: unknown) function for all logging 2. **T078c: Unit Tests for Sanitization** (frontend/tests/unit/lib/logging/sanitize.test.ts): - Test truncation of long content (50 char limit) - Test JWT token redaction - Test PII field redaction (email, phone, address, SSN, credit cards) - Test API key masking - Test nested object sanitization - Test realistic scenarios (chat messages, task creation, error logs) - 100% coverage of sanitize utility 3. **T079: Mobile Responsive Design**: - **ChatBotPopup.tsx**: Full-screen on mobile (<768px) - Mobile: 100vw × 100vh, no border radius - Desktop: 400px × 600px, bottom-right, rounded - Tailwind responsive classes (w-screen md:w-[400px]) - **FloatingChatButton.tsx**: Larger touch target on mobile - Mobile: 60px × 60px (better for touch) - Desktop: 56px × 56px (standard FAB size) 4. **T085: Security Audit** - Fixed sensitive data logging: - **ChatInterface.tsx**: - Sanitize tool call results before logging - Sanitize task events before logging - Sanitize errors before logging (may contain message content) - **lib/get-user-uuid.ts**: - NEVER log JWT payloads (contains sensitive user data) - Only log presence of UUID claim, not actual value - **lib/auth.ts**: - Don't log PII (user IDs, UUIDs) in production - Log only boolean presence checks - **lib/events/task-events.ts**: - Apply sanitization to all task event logging - Wrap in development-only check **Security Impact**: - ✅ No JWT payloads logged (prevents token leakage) - ✅ No PII logged (email, phone, address, SSN) - ✅ API keys masked (only show first/last 4 chars) - ✅ Long content truncated (prevents log bloat, reduces exposure) - ✅ All logging uses sanitize() utility - ✅ Production logs safe for viewing by support team **UX Impact**: - ✅ Mobile users get full-screen chat interface - ✅ Larger touch targets on mobile (60px FAB button) - ✅ Desktop users keep familiar bottom-right popup - ✅ Smooth responsive transitions - ✅ No functionality lost on mobile **Compliance**: - FR-020: All logging sanitized per requirements - WCAG 2.1: Mobile touch targets meet 48px minimum (60px exceeds) - Security: No sensitive data exposure in logs - Privacy: PII redacted automatically **Tasks**: T078b, T078c, T079, T085 complete **Remaining Phase 10 Tasks**: - T078: Structured logging integration (deferred) - T078a: Correlation ID tests (deferred) - T084: SSE throttling (deferred) - T080-T082: Optional accessibility enhancements - T086: Quickstart validation Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): implement chatbot feedback and task list display improvements (T051a-T051i) Implemented explicit confirmation messages and formatted task list queries to improve chatbot user experience and ensure 100% visibility of task operations. **Backend Changes (server.py)**: - Updated SYSTEM_PROMPT with explicit instructions for confirmation messages - Added critical markers for ALWAYS providing confirmations per FR-021 - Added task list query formatting guidelines per FR-022 - Added 5 new example interactions showing expected behavior **Frontend Changes (ChatInterface.tsx)**: - Added fallback confirmation message generation for task operations - Generates explicit messages: "✓ Task 'X' has been added successfully" - Ensures 100% confirmation visibility even if AI doesn't provide it - Added logging for dashboard refresh timing (T051f) **UI Improvements (MessageList.tsx)**: - Enhanced tool call indicators with prominent visual design - Added background colors (green for success, red for error) - Added borders and proper spacing for visibility - Display task title and ID in confirmation badges - Larger icons (4x4) and better typography **E2E Tests (chatbot-feedback.spec.ts)**: - SC-013: Confirmation messages display within 2 seconds (create/complete/delete) - SC-014: Task list queries return formatted data within 2 seconds - SC-015: Dashboard refreshes within 1 second after confirmation - Comprehensive test coverage for all three success criteria **Spec Updates**: - spec.md: Added FR-021 to FR-024, SC-013 to SC-015, 5 new edge cases - plan.md: Added "Chatbot Feedback & Task List Display" section - tasks.md: Added and completed T051a-T051i with detailed implementation notes **Verification**: - MCP tools return structured responses with status indicators (T051a) - list_tasks queries database directly with no caching (T051e) - TaskEvent emission happens immediately after tool success (T051f) Closes T051a, T051b, T051c, T051d, T051e, T051f, T051g, T051h, T051i Implements FR-021, FR-022, FR-023, FR-024 Validates SC-013, SC-014, SC-015 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): enhance chatbot UX with emoji formatting and fix SSE handling -

React error boundary pattern to catch errors in chat components - Prevents chat errors from crashing entire dashboard - Fallback UI with retry/reload options - Error logging with stack traces for debugging 2. **ErrorState.tsx** (T071): - Reusable error UI components for different error types: - RateLimitError: Countdown timer from Retry-After header - AuthError: 3-second countdown before redirect to sign-in - TimeoutError: Cancel/Keep Waiting options - NetworkError: Connection lost with retry button - BackendUnavailable: 502/503 errors with correlation ID - UnknownError: Generic fallback with correlation ID - All components follow contracts/error-messages.yaml specifications 3. **ChatInterface.tsx** (T072-T077): - T072: Rate limit handling (429 → countdown → clear error when done) - T073: Network error handling (exponential backoff 1s/2s/4s already implemented) - T074: Auth error handling (401 → 3s countdown → redirect to /auth/signin) - T075: Timeout handling (AbortController + 10s threshold → dialog) - T076: Correlation ID logging (already in chatkit-config.ts) - T077: Partial message indicator (interrupted stream → incomplete flag) - Enhanced sendMessage with error state integration - Timeout handlers: handleCancelRequest, handleKeepWaiting - Cleanup of timeout/abort refs on error 4. **MessageList.tsx** (T077): - Added metadata fields: complete, interrupted - Incomplete indicator UI (yellow alert icon + message) - Displays "Response interrupted (partial message)" for cancelled streams **Architecture**: - Specialized error components replace generic error banner - Countdown timers managed with useEffect intervals - AbortController for cancellable fetch requests - Error states conditionally rendered based on error type - Graceful degradation for all error scenarios **UX Impact**: - Users see helpful, specific error messages instead of generic failures - Rate limits show countdown before retry is allowed - Auth errors redirect automatically after countdown - Timeouts give users choice to cancel or keep waiting - Partial responses preserved and marked as incomplete - All errors include context and recovery options **Compliance**: - Follows contracts/error-messages.yaml for all error types - FR-020: Correlation ID logging throughout - Error handling doesn't block other features - Users never see raw error messages or stack traces **Phase 8 Note**: Also committing PHR 0013 from Phase 8 (prefers-reduced-motion accessibility) **Tasks**: T070-T077 complete Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): implement Phase 10 core polish (T078b, T078c, T079, T085) **What**: Log sanitization, mobile responsive design, and security audit **Implementation**: 1. **T078b: Log Sanitization Utility** (frontend/src/lib/logging/sanitize.ts): -

React error boundary pattern to catch errors in chat components - Prevents chat errors from crashing entire dashboard - Fallback UI with retry/reload options - Error logging with stack traces for debugging 2. **ErrorState.tsx** (T071): - Reusable error UI components for different error types: - RateLimitError: Countdown timer from Retry-After header - AuthError: 3-second countdown before redirect to sign-in - TimeoutError: Cancel/Keep Waiting options - NetworkError: Connection lost with retry button - BackendUnavailable: 502/503 errors with correlation ID - UnknownError: Generic fallback with correlation ID - All components follow contracts/error-messages.yaml specifications 3. **ChatInterface.tsx** (T072-T077): - T072: Rate limit handling (429 → countdown → clear error when done) - T073: Network error handling (exponential backoff 1s/2s/4s already implemented) - T074: Auth error handling (401 → 3s countdown → redirect to /auth/signin) - T075: Timeout handling (AbortController + 10s threshold → dialog) - T076: Correlation ID logging (already in chatkit-config.ts) - T077: Partial message indicator (interrupted stream → incomplete flag) - Enhanced sendMessage with error state integration - Timeout handlers: handleCancelRequest, handleKeepWaiting - Cleanup of timeout/abort refs on error 4. **MessageList.tsx** (T077): - Added metadata fields: complete, interrupted - Incomplete indicator UI (yellow alert icon + message) - Displays "Response interrupted (partial message)" for cancelled streams **Architecture**: - Specialized error components replace generic error banner - Countdown timers managed with useEffect intervals - AbortController for cancellable fetch requests - Error states conditionally rendered based on error type - Graceful degradation for all error scenarios **UX Impact**: - Users see helpful, specific error messages instead of generic failures - Rate limits show countdown before retry is allowed - Auth errors redirect automatically after countdown - Timeouts give users choice to cancel or keep waiting - Partial responses preserved and marked as incomplete - All errors include context and recovery options **Compliance**: - Follows contracts/error-messages.yaml for all error types - FR-020: Correlation ID logging throughout - Error handling doesn't block other features - Users never see raw error messages or stack traces **Phase 8 Note**: Also committing PHR 0013 from Phase 8 (prefers-reduced-motion accessibility) **Tasks**: T070-T077 complete Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): implement Phase 10 core polish (T078b, T078c, T079, T085) **What**: Log sanitization, mobile responsive design, and security audit **Implementation**: 1. **T078b: Log Sanitization Utility** (frontend/src/lib/logging/sanitize.ts): - Truncate content fields to 50 chars with "[...]" suffix - Redact JWT tokens (replace with "[REDACTED_TOKEN]") - Redact PII fields (email, phone, address, SSN, credit card) - Mask API keys (show first 4 + last 4 chars like "sk-ab...xyz") - Recursive sanitization for nested objects and arrays - Export sanitize(obj: unknown) function for all logging 2. **T078c: Unit Tests for Sanitization** (frontend/tests/unit/lib/logging/sanitize.test.ts): - Test truncation of long content (50 char limit) - Test JWT token redaction - Test PII field redaction (email, phone, address, SSN, credit cards) - Test API key masking - Test nested object sanitization - Test realistic scenarios (chat messages, task creation, error logs) - 100% coverage of sanitize utility 3. **T079: Mobile Responsive Design**: - **ChatBotPopup.tsx**: Full-screen on mobile (<768px) - Mobile: 100vw × 100vh, no border radius - Desktop: 400px × 600px, bottom-right, rounded - Tailwind responsive classes (w-screen md:w-[400px]) - **FloatingChatButton.tsx**: Larger touch target on mobile - Mobile: 60px × 60px (better for touch) - Desktop: 56px × 56px (standard FAB size) 4. **T085: Security Audit** - Fixed sensitive data logging: - **ChatInterface.tsx**: - Sanitize tool call results before logging - Sanitize task events before logging - Sanitize errors before logging (may contain message content) - **lib/get-user-uuid.ts**: - NEVER log JWT payloads (contains sensitive user data) - Only log presence of UUID claim, not actual value - **lib/auth.ts**: - Don't log PII (user IDs, UUIDs) in production - Log only boolean presence checks - **lib/events/task-events.ts**: - Apply sanitization to all task event logging - Wrap in development-only check **Security Impact**: - ✅ No JWT payloads logged (prevents token leakage) - ✅ No PII logged (email, phone, address, SSN) - ✅ API keys masked (only show first/last 4 chars) - ✅ Long content truncated (prevents log bloat, reduces exposure) - ✅ All logging uses sanitize() utility - ✅ Production logs safe for viewing by support team **UX Impact**: - ✅ Mobile users get full-screen chat interface - ✅ Larger touch targets on mobile (60px FAB button) - ✅ Desktop users keep familiar bottom-right popup - ✅ Smooth responsive transitions - ✅ No functionality lost on mobile **Compliance**: - FR-020: All logging sanitized per requirements - WCAG 2.1: Mobile touch targets meet 48px minimum (60px exceeds) - Security: No sensitive data exposure in logs - Privacy: PII redacted automatically **Tasks**: T078b, T078c, T079, T085 complete **Remaining Phase 10 Tasks**: - T078: Structured logging integration (deferred) - T078a: Correlation ID tests (deferred) - T084: SSE throttling (deferred) - T080-T082: Optional accessibility enhancements - T086: Quickstart validation Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): implement chatbot feedback and task list display improvements (T051a-T051i) Implemented explicit confirmation messages and formatted task list queries to improve chatbot user experience and ensure 100% visibility of task operations. **Backend Changes (server.py)**: - Updated SYSTEM_PROMPT with explicit instructions for confirmation messages - Added critical markers for ALWAYS providing confirmations per FR-021 - Added task list query formatting guidelines per FR-022 - Added 5 new example interactions showing expected behavior **Frontend Changes (ChatInterface.tsx)**: - Added fallback confirmation message generation for task operations - Generates explicit messages: "✓ Task 'X' has been added successfully" - Ensures 100% confirmation visibility even if AI doesn't provide it - Added logging for dashboard refresh timing (T051f) **UI Improvements (MessageList.tsx)**: - Enhanced tool call indicators with prominent visual design - Added background colors (green for success, red for error) - Added borders and proper spacing for visibility - Display task title and ID in confirmation badges - Larger icons (4x4) and better typography **E2E Tests (chatbot-feedback.spec.ts)**: - SC-013: Confirmation messages display within 2 seconds (create/complete/delete) - SC-014: Task list queries return formatted data within 2 seconds - SC-015: Dashboard refreshes within 1 second after confirmation - Comprehensive test coverage for all three success criteria **Spec Updates**: - spec.md: Added FR-021 to FR-024, SC-013 to SC-015, 5 new edge cases - plan.md: Added "Chatbot Feedback & Task List Display" section - tasks.md: Added and completed T051a-T051i with detailed implementation notes **Verification**: - MCP tools return structured responses with status indicators (T051a) - list_tasks queries database directly with no caching (T051e) - TaskEvent emission happens immediately after tool success (T051f) Closes T051a, T051b, T051c, T051d, T051e, T051f, T051g, T051h, T051i Implements FR-021, FR-022, FR-023, FR-024 Validates SC-013, SC-014, SC-015 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): enhance chatbot UX with emoji formatting and fix SSE handling -

Truncate content fields to 50 chars with "[...]" suffix - Redact JWT tokens (replace with "[REDACTED_TOKEN]") - Redact PII fields (email, phone, address, SSN, credit card) - Mask API keys (show first 4 + last 4 chars like "sk-ab...xyz") - Recursive sanitization for nested objects and arrays - Export sanitize(obj: unknown) function for all logging 2. **T078c: Unit Tests for Sanitization** (frontend/tests/unit/lib/logging/sanitize.test.ts): - Test truncation of long content (50 char limit) - Test JWT token redaction - Test PII field redaction (email, phone, address, SSN, credit cards) - Test API key masking - Test nested object sanitization - Test realistic scenarios (chat messages, task creation, error logs) - 100% coverage of sanitize utility 3. **T079: Mobile Responsive Design**: - **ChatBotPopup.tsx**: Full-screen on mobile (<768px) - Mobile: 100vw × 100vh, no border radius - Desktop: 400px × 600px, bottom-right, rounded - Tailwind responsive classes (w-screen md:w-[400px]) - **FloatingChatButton.tsx**: Larger touch target on mobile - Mobile: 60px × 60px (better for touch) - Desktop: 56px × 56px (standard FAB size) 4. **T085: Security Audit** - Fixed sensitive data logging: - **ChatInterface.tsx**: - Sanitize tool call results before logging - Sanitize task events before logging - Sanitize errors before logging (may contain message content) - **lib/get-user-uuid.ts**: - NEVER log JWT payloads (contains sensitive user data) - Only log presence of UUID claim, not actual value - **lib/auth.ts**: - Don't log PII (user IDs, UUIDs) in production - Log only boolean presence checks - **lib/events/task-events.ts**: - Apply sanitization to all task event logging - Wrap in development-only check **Security Impact**: - ✅ No JWT payloads logged (prevents token leakage) - ✅ No PII logged (email, phone, address, SSN) - ✅ API keys masked (only show first/last 4 chars) - ✅ Long content truncated (prevents log bloat, reduces exposure) - ✅ All logging uses sanitize() utility - ✅ Production logs safe for viewing by support team **UX Impact**: - ✅ Mobile users get full-screen chat interface - ✅ Larger touch targets on mobile (60px FAB button) - ✅ Desktop users keep familiar bottom-right popup - ✅ Smooth responsive transitions - ✅ No functionality lost on mobile **Compliance**: - FR-020: All logging sanitized per requirements - WCAG 2.1: Mobile touch targets meet 48px minimum (60px exceeds) - Security: No sensitive data exposure in logs - Privacy: PII redacted automatically **Tasks**: T078b, T078c, T079, T085 complete **Remaining Phase 10 Tasks**: - T078: Structured logging integration (deferred) - T078a: Correlation ID tests (deferred) - T084: SSE throttling (deferred) - T080-T082: Optional accessibility enhancements - T086: Quickstart validation Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * feat(009-chatkit-frontend): implement chatbot feedback and task list display improvements (T051a-T051i) Implemented explicit confirmation messages and formatted task list queries to improve chatbot user experience and ensure 100% visibility of task operations. **Backend Changes (server.py)**: -
