Morning Session: Recording & Progress Bugs
src/components/recording/RecordingLifecycle.tsx — debugged and resolved issue where recording time was resetting to zero after stopping recording (commit ce7a98c around 10:34 AM). Root cause was a cleanup function in useEffect triggering when isRecording state changed from true to false, which prematurely reset the recording time before the user could see the final duration. Fixed by using isRecordingRef.current instead of isRecordingState in the cleanup condition to prevent unwanted cleanup. Used an empty dependency array [] to ensure cleanup only runs on component unmount. This ensures users can see how long their recording was after they finish, addressing the critical TWI-1969 issue about recordings being lost when navigating away.useRecordingStore.clean.test.ts (passing 5 tests) and regression-recording-duration.test.ts in the test directory to prevent future recurrence of the recording duration bug. Tests verify recording time persistence through the complete stop recording flow, including basic store state, user recording scenarios with MediaRecorder.stop() calls, blob/file creation validation (checking recordedFile instanceof File with size > 0), and cleanup behavior. All tests now pass successfully with proper mocking of Web Audio API components (MediaRecorder, getUserMedia, AudioContext), providing confidence that this bug won't resurface.useShallow hook from zustand — investigated and resolved "Maximum update depth exceeded" errors caused by unstable Zustand hooks (useRecordingActions, useRecordingState) returning new object references on every store update (even 1-second timer updates), flooding the React tree with re-renders (around 10:05-10:10 AM). Implemented fixes by stabilizing hooks using useShallow from zustand/react/shallow following Zustand best practices. Also identified that the SignInModal component was being defined inside TranscribePage, causing it to be recreated and remounted every second, triggering potential infinite loops. Moved the SignInModal definition outside TranscribePage to prevent this.medianTime and modelBuffer calculations in the progress estimation logic were broken when startProgress incorrectly re-estimated an existing millisecond estimate as seconds. Fixed by passing actual clip duration in seconds to startProgress, reduced baseline time from 10 to 2 seconds, and reduced minimum floor from 5 to 2 seconds for clips under 10 seconds. Now a 6-second clip estimates 12-15 seconds instead of 33, which is much more accurate and doesn't frustrate users with wildly wrong time predictions.Morning-Afternoon: Recording Bubble Refactor & UI Polish
RecordingBubbleContainer.tsx (logic) and RecordingBubbleView.tsx (pure presentational component) around 11:13 AM for better separation of concerns and testability. This makes the codebase cleaner and easier to maintain since logic and UI are now clearly separated following React best practices.AudioContext, AnalyserNode, MediaStreamAudioSourceNode, and requestAnimationFrame (13:18-13:24). Set analyser.fftSize = 256 (initially explored fftSize = 64 at 13:21) and normalized audio levels from 0-1 range. Created three white level bars that respond to microphone input showing live audio feedback to users during recording.#0B4F75 background, circular mic background, proper spacing between UI elements, and better component structure (around 13:36). Made the mic icon bigger to nearly match the bubble size: outer wrapper h-14 w-14 (56px), inner circle h-12 w-12 (48px), and icon scaled to h-7 w-7 (28px) at 14:18. Adjusted gaps between elements using Tailwind spacing: mic-to-bars gap-3 (12px), bars-to-timer gap-4 (16px), timer-to-stop gap-1 (4px). Added subtle hover state to the stop button. Removed the "pinging" animation that was distracting./transcribe without stopping the recording, while clicking the dedicated stop button stops the recording AND navigates to /transcribe (13:36-13:53). Ensured the stop button's click event does not bubble using e.stopPropagation() in multiple places to prevent accidental double-triggering. Added an ActionIconButton for the stop button following the component cleanup plan at 16:47. This creates a much more polished, production-ready recording experience with clear user intent distinction.RecordingBubble.container.test.tsx to isolate and debug functional tests, ensuring bubble-body clicks navigate without stopping, and stop button stops + navigates. All 3 container tests passing (11:24-13:36). Mocked Web Audio API components for deterministic testing. Fixed initial issues where the bubble was not clickable and had no stop button or navigation (13:21), and a "Rendered more hooks" runtime error.Afternoon: Component Refactoring & Testing
ActionIconButton — added JSDocstrings to all button components, replaced boolean props with discriminated unions (e.g., ExpansionState, TranscriptionState, VisibilityState) for clearer state management and type safety (00:30-00:38). Organized all button components into src/components/ui/button/ directory with a barrel export pattern. Updated over 15 import statements across the codebase to use the new barrel export from '@/components/ui/button'. Resolved circular import issues and TypeScript compilation conflicts - build now compiles successfully with proper TypeScript module resolution. Noted pending fix for a borderedPi11 prop typo at 00:30.Sidepanel and focus its search input, removing previous popover behavior (00:09-00:58). Used forwardRef and useImperativeHandle to expose an openAndFocusSearch() method in Sidepanel.tsx with proper cleanup and 50ms timing for focus reliability. Wired this integration across AppNavbar → AppContent → Sidepanel components with proper ref passing. Created comprehensive tests in src/components/tests/[Sidepanel.search](<http://Sidepanel.search>)-focus.test.tsx covering the search focus functionality.useNoScroll hook — created reusable hook that prevents body scrolling on fixed-layout pages (homepage, transcribe page) by locking document body scroll, saving scroll position before locking to prevent jumping when unlocked (13:53-14:40). Implemented proper scrollbar handling with scrollbar-gutter: stable both-edges CSS property to maintain visual consistency across browsers, especially important on Windows Chrome where the scrollbar takes 15-17 pixels of horizontal space. This prevents the annoying layout shift that happens when modals or overlays appear by maintaining the gutter even when scrollbar is hidden.waitFor incorrectly. Ensured all recording bubble container tests and recording store tests pass reliably. Removed problematic tests due to React Testing Library framework incompatibilities causing re-render issues.Afternoon: Storybook Integration & Documentation
App/Transcribe/Components/ProgressIndicator/Container and App/Transcripts/Views/NotesEditor (22:47 on Nov 22 - 00:09). Addressed Module not found errors for @storybook/addon-actions by updating devDependencies. Resolved AuthContext import issues in transcript stories. Created and refined stories for ProgressIndicatorContainer, TranscriptionHeader, UploadSection, TranscribePage, NotesEditor, RecordingBubbleView, and various button components with interactive playgrounds and decorators.estimateProcessingTime function instead of mock, allowing realistic testing of progress behavior without hitting backend rate limits (11:24-11:25). Initially couldn't get the real estimation logic to work because the story was using a mock function. Had to update the story to import and use the actual function from the codebase, then add proper story controls for recording duration and model selection parameters, making it easy to test different scenarios visually. This took some trial and error to get the props and state management working correctly.
