-**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 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.

-**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) -

-**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) -
