-**From Phase 2 (02-backing-track-seek-controls):** -- jamClient must NOT be stored in Redux state - pass as prop instead (non-serializable) -- All jamClient methods in jam-ui return Promises - always use async/await pattern -- jamClient returns string values - always parseInt() before math operations -- End-of-track position requires SessionStopPlay() reset before new playback - -**From Phase 3 Plan 1 (03-backing-track-finalization):** -- Volume control uses mixer system: `SessionSetTrackVolumeData(mixer.id, mixer.mode, trackVolumeObject)` -- Loop control uses direct API: `SessionSetBackingTrackFileLoop(backingTrack.path, shouldLoop)` -- UAT-003 resolved with state machine workaround (stores pending seek, applies on resume) -- Remove conditional fallback code - use correct methods directly - -**From Phase 3 Plan 2 (03-backing-track-finalization):** -- Error types: file (red), network (red), playback (yellow), general (yellow) -- Loading states: isLoadingDuration (track fetch), isOperating (prevent rapid clicks) -- Disabled logic: buttons disabled during loading/operating/error -- Cleanup on unmount: stop playback to prevent stale state -- Network resilience: stop after 3 consecutive polling failures - -**From Phase 3 Plan 3 (03-backing-track-finalization):** -- Performance: Visibility-aware polling (500ms visible, 2000ms hidden) -- Popup mode handling: Check `(isOpen || isPopup)` since popup window = open -- Backing track format: Handle both string (popup) and object (modal) with getBackingTrackPath helper -- Loop handling: Check isLooping flag before stopping at track end -- React optimizations: useCallback for handlers, conditional state updates - -**From Phase 4 Plan 1 (04-jamtrack-research-design):** -- fqId format mandatory: All JamTrack jamClient calls require `{jamTrackId}-{sampleRate}` format -- 8-state sync machine: no_client, initial, packaging, downloading, keying, synchronized, quiet, errored -- JMEP must load before play: `JamTrackLoadJmep(fqId, jmepData)` before `JamTrackPlay(fqId)` -- Mixdown selection: pickMyPackage() filters by ogg/jkz/sample_rate matching client capabilities -- Callback pattern: jamClient download callbacks passed as string names, not function references -- loadJamTrack thunk bug identified: Uses jamTrack.id instead of correct fqId format - -**From Phase 4 Plan 2 (04-jamtrack-research-design):** -- JKSessionJamTrackPlayer follows Backing Track patterns with extensions for download/sync and mixdown selection -- Redux state split: jamTrackState (playback), downloadState (sync machine), availableMixdowns (mixdown cache) -- 6 async thunks needed: loadJamTrack (enhanced), downloadJamTrack, checkJamTrackSync, loadJMEP, seekJamTrack, closeJamTrack -- Enhanced loadJamTrack fixes existing bug: uses fqId format instead of jamTrack.id -- 6-state download/sync machine: idle → checking → downloading → keying → synchronized → error -- Phase 5 preliminary scope: 9 plans, 2.5-3x complexity of Phase 3 Backing Track -- 5 critical decisions deferred to Phase 5: popup mode support, stem control integration, error recovery strategy, download cancellation, UAT deferral threshold -- HIGH risks identified: Download/sync state machine complexity, native client race conditions -- Component architecture: 10 sub-components (PlaybackControls, SeekSlider, TimeDisplay, MixdownPicker, DownloadProgress, ErrorDisplay, SyncStatus, VolumeControl, LoadingSpinner, EmptyState) - -**From Phase 5 Plan 1 (05-jamtrack-implementation):** -- **CRITICAL BUG FIXED**: loadJamTrack now uses fqId format for JamTrackPlay call, unblocking all JamTrack functionality -- fqId construction moved outside conditional block to ensure consistent availability for all jamClient calls -- State organization: Separated concerns with jamTrackState (playback), downloadState (sync machine), mixdown state (availableMixdowns) -- jamTrackState structure: 7 fields tracking real-time playback (isPlaying, isPaused, currentPositionMs, durationMs, selectedMixdownId, playbackMode, lastUpdate) -- downloadState structure: 8 fields tracking 6-state machine (jamTrackId, mixdownId, fqId, state, progress, currentStep, totalSteps, error) -- Mixdown management: availableMixdowns array, activeMixdown object, mixdownCache map for efficient package lookups -- UI preferences: openJamTrack tracks currently open player, jamTrackUI stores user preferences (lastUsedMixdownId, volume) -- Redux foundation complete: 10 new reducers and 8 new selectors across 3 slices ready for Phase 5 Plans 2-5 - -**From Phase 5 Plan 2 (05-jamtrack-implementation):** -- Enhanced loadJamTrack checks sync state and triggers download if needed before playback -- downloadJamTrack uses global window callbacks for native client integration (callbacks passed as string names) -- seekJamTrack applies UAT-003 fix pattern (pending seek while paused, applied on resume) -- WebSocket handlers parse messages correctly with parseInt for numbers -- Thunks can dispatch other thunks using dispatch().unwrap() pattern -- Global callbacks named as strings for native client callback pattern (window.jamTrackDownloadProgress, etc.) -- Component cleanup on unmount with closeJamTrack thunk prevents memory leaks -- Component initialization pattern: buildFqId → check sync → autoPlay -- 6 async thunks complete: loadJamTrack (enhanced), downloadJamTrack, checkJamTrackSync, loadJMEP, seekJamTrack, closeJamTrack -- 3 WebSocket handlers active: MIXER_CHANGES (extended for mixdowns), JAM_TRACK_CHANGES (enhanced), MIXDOWN_CHANGES (new) - -**From Phase 5 Plan 3 (05-jamtrack-implementation):** -- Reused Phase 3 Backing Track patterns for consistency (visibility-aware polling, UAT-003 fix, error handling) -- Playback controls with jamClient: JamTrackPlay/Pause/Resume/Stop/SeekMs -- Visibility-aware polling: 500ms visible, 2000ms hidden for position/duration updates -- Conditional state updates in polling (only dispatch if values changed) -- isOperating flag prevents rapid clicks during async operations -- formatTime utility for consistent MM:SS time display -- End-of-track handling: automatic stop and reset when position >= duration -- handleSeek with UAT-003 fix: pendingSeekRef for pause-seek-resume flow - -**From Phase 5 Plan 4 (05-jamtrack-implementation):** -- Mixdown fetching during initialization (after sync check, non-fatal if fails) -- Default mixdown selection: prefer master, fallback to first available -- Mixdown change stops and restarts playback with new mixdown if playing/paused -- Visual indicators for mixdown types: 🎵 master, 🎨 custom, 🎸 stem -- Download UI visibility: show only for active states (checking/downloading/keying/error), hide for idle/synchronized -- Step indicator conditionally rendered only when totalSteps > 0 -- handleMixdownChange, handleCancelDownload, handleRetryDownload with useCallback -- 6-state download machine UI: checking, downloading (with progress), keying, error (with retry) - -**From Phase 5 Plan 5 (05-jamtrack-implementation):** -- 5 error types with color coding: FILE/NETWORK/DOWNLOAD (red), PLAYBACK/GENERAL (yellow) -- handleRetryError with type-specific retry logic (download/file → retry download, network → re-initialize) -- Network resilience: consecutiveFailuresRef tracks failures, stop polling after 3 consecutive failures -- Edge case validation: null jamClient shows "Native client not available", invalid jamTrack data caught -- Performance optimizations: useMemo for formattedPosition/formattedDuration/progressPercent -- All 11 handlers use useCallback for memoization -- React.memo at component export for render optimization -- Clean console output: removed all diagnostic console.log, kept only console.error -- UAT validated: 40+ test cases across 9 categories (initialization, download, playback, seek, mixdown, display, errors, performance, cleanup) - -**From Phase 6 Plan 1 (06-session-chat-research-design):** -- Legacy chat architecture: React CoffeeScript + Reflux + jQuery hybrid with multi-channel support (global, session, lesson) -- Chat API: 2 REST endpoints (POST/GET /api/chat), WebSocket Protocol Buffer messages (CHAT_MESSAGE type) -- Database: chat_messages table with channel, purpose, attachments, indexed by channel/created_at/session_id -- Read/unread tracking: Only exists for lesson chat (teacher_unread_messages, student_unread_messages flags) - - Session/global chat has NO persistent tracking (badge resets on open) - - NEW functionality needed: client-side unread tracking with Redux + localStorage -- React patterns available: WindowPortal (modeless dialog), lobbyChatMessagesSlice (lobby chat reference), useSessionWebSocket (WebSocket integration) -- Gaps identified: No sessionChatSlice, no multi-channel state, no message deduplication, no unread tracking per channel -- TDD candidates: All data layer (Redux, API, WebSocket), component behavior (send, scroll, unread badge) -- Key decisions: WindowPortal for chat window, keyed message storage by channel, client-side unread tracking, file attachments deferred -- 3 documentation files created: CHAT_LEGACY.md (679 lines), CHAT_API.md (798 lines), CHAT_REACT_PATTERNS.md (1255 lines) - -**From Phase 6 Plan 2 (06-session-chat-research-design):** -- Component architecture: 8 components (JKSessionChatButton, JKSessionChatWindow + 6 sub-components) -- Component hierarchy: WindowPortal wrapper → Header → MessageList (with auto-scroll) → Messages + Composer -- Props vs Redux: Heavy Redux usage (minimal props), only callbacks passed as props -- Auto-scroll logic: Track isUserScrolling state, disable auto-scroll when user scrolls up, re-enable at bottom -- sessionChatSlice design: Multi-channel state (messagesByChannel keyed by channel ID), unreadCounts per channel, lastReadAt timestamps -- 7 reducers: addMessageFromWebSocket (deduplicate by msg_id), setActiveChannel, openChatWindow (reset unread), closeChatWindow, markAsRead, incrementUnreadCount, setWindowPosition -- 3 async thunks: fetchChatHistory (REST API), sendMessage (optimistic update), markMessagesAsRead (future server-side) -- 8 memoized selectors: selectChatMessages, selectUnreadCount, selectTotalUnreadCount, selectIsChatWindowOpen, selectActiveChannel, selectFetchStatus, selectSendStatus, selectSendError -- WebSocket integration: CHAT_MESSAGE handler in useSessionWebSocket, Protocol Buffer to Redux conversion, unread increment if window closed -- Read/unread tracking: Client-side with localStorage persistence (NEW functionality), lastReadAt timestamps, server-side deferred to next milestone -- Phase 7-11 roadmap: 11-13 plans estimated, 28-32 tasks, 1.5-2x complexity of Backing Track, 0.6x complexity of JamTrack -- Risk analysis: 2 HIGH (WebSocket deduplication, localStorage edge cases), 4 MEDIUM (auto-scroll, multi-tab sync, API errors, WindowPortal styling), 2 LOW (character count, timestamp formatting) -- TDD strategy: Phase 7 100% (data layer), Phase 8 50% (behavior), Phase 9 100% (composition), Phase 10 100% (unread tracking), Phase 11 70% (error handling) -- Testing strategy: 80%+ unit test coverage, 7 integration test files, E2E complete workflow, 40+ UAT test cases across 9 categories -- Critical decisions: Message virtualization deferred, optimistic UI updates enabled, localStorage for unread persistence, multi-tab sync deferred, auto-scroll tracks scroll position -- Deferred features: Server-side read/unread tracking, file attachments, message search/filtering, editing/deletion, typing indicators, emoji picker, multi-channel tabs, notification sounds, desktop notifications - -**From Phase 7 Plan 1 (07-chat-infrastructure):** -- Created sessionChatSlice.js with complete initial state structure matching CHAT_REDUX_DESIGN.md -- Implemented 7 reducers using strict TDD: addMessageFromWebSocket, setActiveChannel, openChatWindow, closeChatWindow, markAsRead, incrementUnreadCount, setWindowPosition -- Comprehensive unit test suite with 40 tests and 100% reducer coverage -- Message deduplication logic validated (critical for WebSocket + REST scenario) -- Unread tracking system tested across multi-channel scenarios -- Channel key construction: session uses sessionId directly, lesson uses lessonSessionId, global uses 'global' -- Registered sessionChat slice in Redux store configuration -- Commit history: 6 commits following TDD RED-GREEN phases - -**From Phase 7 Plan 2 (07-chat-infrastructure):** -- REST API methods: getChatMessages (fetch with pagination), sendChatMessage (send to channel) -- Native fetch API used instead of apiFetch wrapper for explicit control over credentials/headers -- fetchChatHistory async thunk: pending/fulfilled/rejected lifecycle with message deduplication and sorting -- sendMessage async thunk: optimistic UI updates with pending (add temp message), fulfilled (replace), rejected (remove) -- createOptimisticMessage helper extracted for code clarity -- Message deduplication prevents duplicates from WebSocket + REST scenario -- Chronological sorting (createdAt ASC) maintains proper message order -- Pagination cursor storage in nextCursors state for infinite scroll -- 67 total tests passing: 14 REST API tests, 53 Redux slice tests -- Test coverage: 100% for all async operations and state transitions -- Commit history: 7 commits following TDD RED-GREEN-REFACTOR phases - -**From Phase 7 Plan 3 (07-chat-infrastructure):** -- CHAT_MESSAGE WebSocket handler: transforms Protocol Buffer format (msg_id, user_id, etc.) to Redux format -- Channel key construction: session uses session_id directly, lesson uses lesson_session_id, global uses 'global' literal -- Unread increment logic: increment if window closed OR viewing different channel, do NOT increment if window open and viewing same channel -- getChannelKeyFromMessage() helper function extracted for reusability across WebSocket and Redux -- useSelector in WebSocket hook to access real-time chat state for unread logic -- 8 memoized selectors using Reselect: selectChatMessages, selectUnreadCount, selectTotalUnreadCount, selectIsChatWindowOpen, selectActiveChannel, selectFetchStatus, selectSendStatus, selectSendError -- localStorage utilities: saveLastReadAt, loadLastReadAt, clearLastReadAt with graceful error handling -- localStorage integration: load on Redux initialization, save on openChatWindow and markAsRead actions -- Storage key: 'jk_chat_lastReadAt' with JSON format: { "channel-id": "ISO-timestamp", ... } -- Error handling strategy: catch without throwing, console.error for debugging, return empty object on parse errors -- 90 total tests passing: 14 WebSocket, 68 Redux/selectors, 8 localStorage -- Test coverage: 100% for all WebSocket routing, selector memoization, and localStorage operations -- Commit history: 9 commits following strict TDD RED-GREEN-REFACTOR phases (3 commits per task) - -**From Phase 8 Plan 1 (08-chat-window-ui):** -- Chat window follows WindowPortal pattern from Phase 3-5 media players (BackingTrack/JamTrack/Metronome) -- Window dimensions: 450×600px per design spec from CHAT_COMPONENT_DESIGN.md -- JKChatHeader component: channel name display + close button with inline styles -- JKSessionChatWindow component: WindowPortal wrapper with Redux integration (isWindowOpen, activeChannel, closeChatWindow) -- Integration point: JKSessionScreen renders JKSessionChatWindow after JamTrack modal -- Conditional rendering: window only appears when isWindowOpen is true -- Redux store exposed for testing: window.__REDUX_STORE__ in dev/test environments only -- React.memo on JKSessionChatWindow for performance (pure component with no props) -- Integration tests: 3 tests validate window open/close behavior and placeholder visibility -- Inline styles used for MVP (SCSS styling deferred to Plan 8.3) -- Placeholder content area ready for message list implementation (Plan 8.2) - -**From Phase 8 Plan 2 (08-chat-window-ui):** -- formatTimestamp utility with dayjs: "Just now" → "X minutes ago" → "X hours ago" → "Yesterday" → day name → MM/DD/YYYY -- JKChatMessage component: avatar with initials, sender name, message text, relative timestamp, React.memo for performance -- JKChatLoadingSpinner and JKChatEmptyState: stateless components for loading and empty states -- JKChatMessageList with auto-scroll: 50px bottom threshold, 300ms debounce, smooth scrolling -- Auto-scroll state machine: disabled on manual scroll, re-enabled when user scrolls to bottom -- Auto-scroll triggers on messages.length change (not individual message objects) -- Testing libraries: @testing-library/react@12 and @testing-library/jest-dom@5 (React 16 compatible) -- Mock Element.prototype.scrollTo for JSDOM compatibility in tests -- TDD methodology: 6 tests for formatTimestamp, 3 tests for JKChatMessageList behavior -- All 77 chat-related tests passing (formatTimestamp: 6, JKChatMessageList: 3, sessionChatSlice: 68) -- Performance optimizations: React.memo on JKChatMessage, useCallback on all handlers -- Message list integrated into JKSessionChatWindow, replacing placeholder content - -**From Phase 8 Plan 3 (08-chat-window-ui):** -- JKSessionChatButton component with unread badge: sessionId prop, inline styles, badge positioning -- Badge visibility logic: hidden when count = 0, shows 1-99, shows "99+" for counts >= 100 -- Badge positioning: absolute at top-right with -6px offset, red background (#dc3545) -- Click handler: opens chat window and sets active channel (openChatWindow, setActiveChannel) -- Visual feedback: reduced opacity (0.6) when window already open -- Integration: replaced placeholder Chat button in JKSessionScreen navigation -- SCSS deferred: inline styles sufficient for MVP, SCSS can be added later for hover effects -- Integration tests: 7 tests covering badge visibility, click behavior, duplicate prevention -- getBadgeText() helper: formats unread count with overflow prevention -- useCallback optimization: handleClick memoized to prevent re-renders - -**From Phase 9 Plan 1 (09-message-composition):** -- JKChatComposer component with controlled textarea, character validation, keyboard handling -- Local state for inputText (ephemeral, no Redux persistence needed) -- Character validation: trim whitespace, 1-255 characters after trim -- Three-tier visual feedback: gray (0-230 chars), yellow (231-255 approaching), red (256+ over limit) -- Keyboard handling: Enter to send, Shift+Enter for newline (standard chat UX) -- Disabled states: textarea/button disabled when !isConnected OR isSending OR !isValid -- Validation messages: over-limit count, empty after trim, disconnected warning -- Error display: sendError shows "Failed to send message. Please try again." -- React.memo optimization with useCallback for all handlers - -**From Phase 9 Plan 2 (09-message-composition):** -- Chat window flex layout: header fixed at top, message list scrollable (flex: 1), composer fixed at bottom -- WindowPortal three-section structure ensures proper space distribution and scrolling -- WebSocket testing approach: direct Redux dispatch to simulate messages (simpler than full WebSocket mocking) -- Separate test files for send vs receive flows (better organization and maintainability) -- Integration tests: 11 total (7 send flow, 4 receive flow) covering end-to-end scenarios - -**From Phase 10 Plan 1 (10-read-unread-status):** -- Comprehensive integration test suite: 17 tests validating unread badge and localStorage persistence -- Test approach: Playwright tests with Redux store access (window.__REDUX_STORE__) for direct state manipulation -- Popup handling: Dispatch Redux actions directly (openChatWindow/closeChatWindow) instead of UI clicks - WindowPortal doesn't create real popups in test environment -- Locator strategy: Use .first() to handle strict mode violations with multiple matching elements -- Badge tests (8): hidden/visible states, count display (1-99, "99+"), reset on open, increment logic (closed window vs different channel), multiple messages, page reload persistence -- localStorage tests (7): save/load lastReadAt, multi-channel independence, quota exceeded handling, corrupted data handling, page reload survival -- E2E tests (2): complete 12-step workflow, multi-channel switching scenarios -- Current implementation behavior: Unread increments for ALL messages when window closed, regardless of message timestamp vs lastReadAt -- Expected behavior noted: Future enhancement could filter by timestamp (messages with createdAt > lastReadAt) -- Test results: 16/17 passing (94% pass rate) - validates Redux state, localStorage, UI rendering - -**From Phase 11 Plan 1 (11-chat-finalization):** -- Error handling: Color-coded displays (red for critical API failures, yellow for WebSocket disconnection warnings) -- clearSendError Redux action enables retry functionality for failed sends -- Retry pattern: Button clears error and re-enables input without auto-resending (prevents duplicate sends) -- Accessibility: Comprehensive ARIA attributes (role="dialog", aria-labelledby, aria-describedby, aria-invalid, aria-live) -- ARIA decisions: aria-modal="false" for modeless WindowPortal dialog, live regions for validation messages -- Keyboard navigation: Escape closes window, Tab order preserved, Enter sends message -- Focus management: Auto-focus textarea on window open with 100ms delay for DOM readiness -- Edge cases validated: Rapid actions, disconnection handling, empty states, long messages all working correctly -- All edge cases already handled by existing implementation from Phases 7-10, verified as robust - -**From Phase 11 Plan 2 (11-chat-finalization):** -- UAT checklist organization: 50+ test cases across 9 categories for systematic manual verification -- P0 bug triage workflow: Immediate fix → test verification → documentation → continue execution -- P0 critical bug fixed: sendChatMessage parameter name corrected (session_id → music_session) -- Root cause: Frontend/backend parameter mismatch causing ActiveRecord.find(nil) → 404 error -- Integration test lesson: Mock-based tests missed API contract mismatch; actual backend integration needed -- Milestone v1.1 validation complete: All P0/P1 issues resolved, ready for production deployment -- v1.1 Music Session Chat milestone COMPLETE (Phases 6-11, 11 plans total) - -**From Phase 12 Plan 1 (12-attachment-research-&-backend-validation):** -- Backend requires NO changes: Existing /api/music_notations endpoint is fully functional with S3 integration -- FormData critical pattern: processData: false (jQuery) / no Content-Type header (fetch) - browser auto-adds multipart boundary -- Client-side validation mandatory: 10 MB limit, extension whitelist, attachment type detection before upload -- WebSocket message delivery: Backend auto-creates ChatMessage after upload, React waits for broadcast (don't manually add) -- S3 signed URL workflow: URLs expire in 120 seconds, must re-fetch for each download attempt -- Legacy as reference only: Document CoffeeScript/Reflux/jQuery patterns but implement fresh with React/Redux/fetch -- File type discrepancy identified: Requirements specify .mp3 but backend whitelist missing it (needs resolution in Phase 13) - -**From Phase 12 Plan 2 (12-attachment-research-&-backend-validation):** -- Backend validation complete: 95% ready (pending mp3 format decision) -- Zero backend changes required except mp3 whitelist decision (requirements have .mp3, backend doesn't) -- React integration strategy designed: 7 component modifications + 2 new files = ~430 lines + ~200 test lines -- JKChatAttachButton: Hidden file input + visible button trigger pattern (60 lines) -- attachmentValidation.js service: validateFileSize, validateFileType, getAttachmentType utilities (80 lines) -- sessionChatSlice extensions: uploadState (status, progress, error, fileName), uploadAttachment thunk (120 lines) -- REST helpers: uploadMusicNotation (FormData via native fetch), getMusicNotationUrl (signed URL) (40 lines) -- JKChatComposer modifications: Integrate attach button, file validation, upload error display (80 lines) -- JKChatMessage modifications: Detect attachment messages, render file links, fetch signed URLs (40 lines) -- JKSessionScreen modifications: Extract attachment fields from WebSocket CHAT_MESSAGE payload (10 lines) -- Key decision: Use native fetch() for FormData (NOT apiFetch) - browser must set Content-Type with boundary -- Implementation sequence: Phase 13 (upload), Phase 14 (display), Phase 15 (sync), Phase 16 (errors) -- Requirements coverage: 19/19 mapped to phases (100%) -- 2 documentation files created: BACKEND_VALIDATION.md (547 lines), REACT_INTEGRATION_DESIGN.md (1319 lines) - -**From Phase 13 Plan 1 (13-file-upload-infrastructure):** -- File validation service with strict TDD methodology (RED-GREEN-REFACTOR cycle) -- 5 exported functions: validateFileSize (10 MB), validateFileType (10 extensions), getAttachmentType (audio/notation), validateFile (combined), formatFileSize (B/KB/MB) -- Extension whitelist: .pdf, .xml, .mxl, .txt, .png, .jpg, .jpeg, .gif, .mp3, .wav -- Backend compatibility: warns about .mp3 (frontend allows, backend doesn't support yet) -- Pure utility functions: no external dependencies, easy to test -- 100% test coverage: 37 test cases covering all functions and edge cases -- Extension validation: case-insensitive matching (DOCUMENT.PDF accepted) -- Fail-fast validation: size checked before type to minimize computation -- Custom size limits: validateFileSize accepts optional maxSizeBytes parameter for future flexibility - -**From Phase 13 Plan 2 (13-file-upload-infrastructure):** -- Redux upload state management: uploadState with status, progress, error, fileName fields in sessionChatSlice -- uploadAttachment async thunk: FormData construction, HTTP 413/422 error mapping, rejectWithValue error handling -- REST helpers: uploadMusicNotation (native fetch), getMusicNotationUrl (apiFetch for JSON) -- Critical pattern: uploadMusicNotation uses native fetch (NOT apiFetch) - browser must set Content-Type with multipart boundary -- 5 upload selectors: selectUploadStatus, selectUploadError, selectUploadProgress, selectUploadFileName, selectIsUploading -- Error handling: 413 → "File too large - maximum 10 MB", 422 → "Invalid file type or format" -- TDD methodology: 30+ tests written before implementation, all upload tests passing (85/88 total, 3 pre-existing failures) -- Attachment type detection: audio extensions (.mp3, .wav, .flac, .ogg, .aiff, .aifc, .au) vs notation (everything else) -- FormData fields: files[] (File), session_id (string), attachment_type ('notation'|'audio') - -**From Phase 13 Plan 3 (13-file-upload-infrastructure):** -- Attach button in session toolbar: Hidden file input + visible button trigger pattern (NOT in chat composer per REQ-1.1) -- Pre-upload validation: validateFile() runs before dispatch(uploadAttachment()) to prevent wasted network requests -- File input accept attribute: .pdf,.xml,.mxl,.txt,.png,.jpg,.jpeg,.gif,.mp3,.wav (matches ALLOWED_EXTENSIONS) -- Auto-open chat window: dispatch(openModal('chat')) before upload so user sees progress -- Button state during upload: disabled={isUploading}, text shows "Uploading..." vs "Attach" -- Upload progress component: JKChatUploadProgress with Spinner, styled as system message (gray background, italic) -- Upload progress display: Rendered at bottom of JKChatMessageList when isUploading && uploadFileName -- Error feedback: Toast notifications for validation errors (size/type) and upload errors -- User verification complete: File dialog opens, invalid files rejected, valid files upload to backend (201 Created) -- Integration pattern: attachFileInputRef.current?.click() to trigger OS file dialog from visible button - -**From Phase 14 Plan 1 (14-chat-integration-and-display):** -- Attachment message identification: isAttachmentMessage = attachmentId && attachmentName check (lines 90-158) -- Attachment visual styling: Light blue background (#e3f2fd), paperclip icon, distinct from text messages -- Metadata display format: "[UserName] attached [FileName]" with size, uploader, timestamp -- File size formatting: formatFileSize() utility (B/KB/MB) from attachmentValidation.js -- WebSocket transformation: JKSessionScreen handleChatMessage flattens attachment fields (attachmentId, attachmentName, attachmentType, purpose, attachmentSize) -- Message sorting: Attachments sort chronologically with text messages by createdAt ASC - -**From Phase 14 Plan 2 (14-chat-integration-and-display):** -- Clickable attachment links: handleAttachmentClick fetches signed URL via getMusicNotationUrl() -- S3 signed URL pattern: Backend returns temporary URL, frontend opens in new tab (target="_blank") -- Browser-native handling: window.open delegates view/download to browser based on Content-Type -- Responsive layout: maxWidth with textOverflow: ellipsis for long filenames, title attribute for hover -- Filename truncation: CSS ellipsis with full filename in title tooltip -- All 89 sessionChatSlice tests passing (fixed 3 pre-existing bugs during phase 14-03) - -**From Phase 14 Plan 3 (14-chat-integration-and-display - Gap Closure):** -- Dual-path message normalization: REST API and WebSocket both produce flat attachment fields -- REST API transformation: fetchChatHistory.fulfilled flattens music_notation nested object to match WebSocket format -- Attachment field mapping: music_notation.id → attachmentId, file_name → attachmentName, attachment_type → attachmentType -- attachmentSize handling: null for REST API (unavailable), populated for WebSocket -- Gap closure: Attachments now persist across page refresh and display when joining session with history -- Transform at Redux boundary: Keep component simple by providing consistent data shape from both paths - -**From Phase 14 Plan 1 (14-chat-integration-and-display):** -- WebSocket transformation: CHAT_MESSAGE handler extracts attachment fields (attachmentId, attachmentName, attachmentType, purpose, attachmentSize) -- Attachment detection pattern: Check message.attachmentId && message.attachmentName presence -- Visual distinction: Light blue background (#e3f2fd) for attachments vs gray (#f8f9fa) for text messages -- Message format: "[UserName] attached [FileName] (size)" with paperclip emoji (📎) -- Graceful size handling: Display file size only if present (backend may not always include attachmentSize) -- Accessibility: Paperclip emoji uses role="img" and aria-label="attachment" for screen readers -- PropTypes updated: message field optional (attachment-only messages may not have text content) - -**From Phase 14 Plan 2 (14-chat-integration-and-display):** -- Clickable attachment links: Fetch signed S3 URLs on demand (not pre-fetch to avoid 120-second expiration) -- Signed URL workflow: handleAttachmentClick calls getMusicNotationUrl, opens window.open(url, '_blank') -- Browser-native file handling: Backend sets Content-Type, browser displays PDF/images or downloads other types -- Responsive filename truncation: CSS-based with maxWidth + textOverflow: ellipsis + title attribute for hover -- Loading state: isLoadingUrl prevents rapid multiple clicks with cursor: 'wait' styling -- Flex layout pattern: minWidth: 0 on flex parent required for text-overflow: ellipsis to work -- Phase 14 COMPLETE: All attachment display and interaction features delivered - -**From Phase 15 Plan 1 (15-real-time-synchronization):** -- WebSocket handler verified: extracts attachmentId, attachmentName, attachmentType, purpose, attachmentSize -- Deduplication confirmed: both WebSocket and REST API paths use message.id for deduplication -- Backend excludes sender from WebSocket broadcast (server_publish_to_session uses exclude_client_id) -- Optimistic update added for uploader: constructs message from MusicNotation response + user info -- Chat history fetch fixed: was never being called, now dispatches on channel activation -- API parameter name fixed: backend expects `music_session` not `session_id` -- API response field fixed: backend returns `chats` not `messages` -- Known limitation: WebSocket only broadcasts to musicians (as_musician: true filter) - -**From Phase 16 Plan 1 (16-attachment-finalization):** -- Success toast triggers on upload status transition (uploading → idle) with 3-second auto-close -- Validation error messages standardized to exact requirements wording (REQ-5.1, REQ-5.2) -- Network error message updated to "Upload failed. Please try again." (REQ-5.3) -- S3 404 error handling: shows "File no longer available" toast instead of silent failure (REQ-5.5) -- Integration tests created: 5 Playwright tests covering all error scenarios (file size, success, network, S3 404, rapid clicks) -- Error handling pattern: Toast notifications for all error and success states -- useRef pattern for tracking previous state values in status transition detection +See `.planning/milestones/v1.2-ROADMAP.md` for v1.2 decisions. ### Deferred Issues -**From Phase 3 Plan 3 UAT:** - -1. **End-of-track restart requires double-click** (Minor) - - First click doesn't start playback, second click required - - Root cause: Race condition between component/native client state - - Needs: Investigation of native client state machine - -2. **Loop functionality not working** (Medium) - - Loop checkbox can be enabled but track doesn't restart at end - - Root cause: Native client doesn't respect SessionSetBackingTrackFileLoop - - Needs: Verify jamClient API or implement loop manually in React - -3. **Volume control not working in popup mode** (Medium) - - Architectural limitation: backingTrackMixers empty in popup mode - - Root cause: Mixer system not available without Redux state - - Needs: Architecture refactor or document as modal-only feature - -4. **WebSocket chat messages only broadcast to musicians** (Medium) - - Backend's `server_publish_to_session` uses `as_musician: true` filter - - Root cause: `mq_router.rb` line 42 filters recipients to musicians only - - Impact: Listeners/fans without audio tracks don't receive real-time WebSocket messages - - Workaround: Messages visible after page refresh (REST API doesn't have this filter) - - Fix: Change `chat_message.rb` to use `server_publish_to_everyone_in_session` - - Blocker: Backend changes out of scope for v1.2 +1. **End-of-track restart requires double-click** (Minor) - From v1.0 +2. **Loop functionality not working** (Medium) - From v1.0 +3. **Volume control not working in popup mode** (Medium) - From v1.0 +4. **WebSocket chat messages only broadcast to musicians** (Medium) - From v1.2 +5. **mp3 backend support** (Medium) - Frontend allows, backend whitelist doesn't support ### Roadmap Evolution -- **v1.0 Media Players** (Phases 1-5): Completed 2026-01-14 - Backing Track and JamTrack modernization -- **v1.1 Music Session Chat** (Phases 6-11): Completed 2026-01-31 - Real-time chat with read/unread tracking -- **v1.2 Session Attachments** (Phases 12-16): Started 2026-02-02 - File attachment capability for sessions - -### Blockers/Concerns - -1. **mp3 Format Support Decision Required** (MEDIUM priority) - - Requirements specify .mp3 audio file support - - Backend MusicNotationUploader whitelist does NOT include mp3 - - Options: (A) Add mp3 to backend whitelist (1-line change), (B) Remove mp3 from requirements - - Recommendation: Add mp3 support to backend (user convenience, minimal effort) - - Impact: Can proceed with Phase 13 implementation with TODO marker if needed - - Decision owner: Product/Engineering +- **v1.0 Media Players** (Phases 1-5): Shipped 2026-01-14 +- **v1.1 Music Session Chat** (Phases 6-11): Shipped 2026-01-31 +- **v1.2 Session Attachments** (Phases 12-16): Shipped 2026-02-07 +- **v1.3 TBD**: Not started ## Session Continuity -Last session: 2026-02-07T04:38:40Z -Stopped at: Completed 16-01-PLAN.md (Error handling & user feedback) +Last session: 2026-02-07 +Stopped at: v1.2 milestone complete Resume file: None -**Status:** Phase 16 Plan 1 COMPLETE — Error handling and user feedback implemented +**Status:** Ready for next milestone **Next steps:** -1.
