.nvmrc pinning Node.js version
Project structure section in README
Markdown linting via markdownlint-cli2
LearnScreen and PracticeScreen test suites
Store failure-path and edge-case tests (carry propagation, timeout lifecycle)
hintHelpTimeoutRef to track and cancel hint help setTimeout on unmount
hintInitRef reset when hints are disabled (allows re-initialization on re-enable)
ErrorBoundary integrated into Expo Router layout

Moved _timeoutId from Zustand store state to module-scoped variable (avoids serialization issues and unnecessary re-renders)
Replaced generateProblem() retry loop with direct range generation (MIN + random * (MAX - MIN))
Replaced magic numbers in isValidProblem with imported constants
Scoped Animated.timing mock in PracticeScreen tests to beforeAll/afterAll
Made carry propagation tests deterministic with retry loops and explicit isComplete assertions
Renamed vacuous hint enforcement test to reflect actual behavior (enforcement is in UI, not store)

Fixed handleAnswerPress dependency array (removed stale answerChoices/correctAnswerIndex)
Fixed SettingsScreen indentation inconsistency
Updated SettingsScreen test afterEach to reset all fields matching beforeEach
Updated README badge images with alt text (MD045 compliance)
Fixed nested code fences in Phase-4 plan doc
Fixed deployment_target in health-audit metadata to "Mobile (iOS/Android) + Expo Web"
Updated Phase-1 plan to reflect completed status
Archived manual-validation.md to docs/manual-validation-archive.md with redirect
Fixed README: tutorial step count (21), navigation framework (Expo Router), clone path, removed false AsyncStorage claim
Renamed package from expo-project to react-trachtenberg
Fixed JSDoc move range from 0-23 to 0-32 in hint utilities
