📋 Daily Codebase Review - 2026-02-04

[claude]

Executive Summary

The Sobers codebase is in good overall health with strong architecture, comprehensive testing infrastructure (85% coverage threshold), and excellent security practices including privacy-aware error tracking. Primary areas for attention are a skipped test suite that needs fixing and some minor type-safety improvements in utility functions.

Health Score: B+

Justification: The codebase demonstrates solid engineering practices including semantic theming, proper memoization in key components, comprehensive input validation, and privacy-first error handling. The main deductions are for: (1) skipped tests indicating technical debt, (2) minor any type usage in privacy sanitization code, and (3) opportunity for more memoization in list rendering components.

Top 5 Priority Items

Priority	Item	Severity	Effort	File(s)
1	Fix skipped MeetingsScreen test suite	Medium	Medium	__tests__/app/program/meetings.test.tsx:106
2	Add missing tests for program screens (daily, literature)	Medium	Medium	app/(app)/(tabs)/program/daily.tsx, literature.tsx
3	Improve type safety in sentry-privacy.ts	Low	Low	lib/sentry-privacy.ts:238,254
4	Add memoization to MeetingListItem and MeetingsCalendar	Low	Low	components/program/MeetingListItem.tsx, MeetingsCalendar.tsx
5	Fix skipped navigation test	Low	Low	__tests__/app/program-layout.test.tsx:174

Detailed Findings

1. Code Health & Technical Debt

✅ Strengths:

• Clean project structure with clear separation of concerns
• Consistent use of @/ path aliases
• StyleSheet.create used consistently (69 occurrences)
• No raw Palette colors in app screens - semantic theming followed correctly
• Good use of useMemo/useCallback (200+ occurrences combined)

⚠️ Areas for Improvement:

• Skipped tests detected:
  • __tests__/app/program/meetings.test.tsx:106 - describe.skip('MeetingsScreen') with TODO comment about mock setup
  • __tests__/app/program-layout.test.tsx:174 - it.skip('navigates to literature')
• Minor any type usage:
  • lib/sentry-privacy.ts:238 - sanitizeObject(obj: any, visited = new WeakSet()): any
  • lib/sentry-privacy.ts:254 - const sanitized: any = {}
  • lib/supabase.ts:284 - (client as any)[prop]
• TODO comments: 1 actionable TODO found at __tests__/app/program/meetings.test.tsx:105

2. Security Audit

✅ Excellent Practices:

• No hardcoded secrets - all credentials use process.env.EXPO_PUBLIC_* pattern
• No eval() or new Function() usage
• Comprehensive input validation in lib/validation.ts:
  • Email validation with proper regex
  • Password requirements (8+ chars, uppercase, lowercase, number, symbol)
  • Display name validation with Unicode support
• Row-level security policies in Supabase migrations (37 migration files)
• Privacy-aware Sentry integration with OAuth token scrubbing
• Sensitive field filtering (password, token, access_token, refresh_token, email)

✅ No Issues Found:

• No dangerouslySetInnerHTML usage
• Environment variables properly namespaced
• OAuth tokens properly sanitized in breadcrumbs and error events

3. Test Coverage Gaps

⚠️ Missing Test Files:

• No dedicated tests for app/(app)/(tabs)/program/daily.tsx
• No dedicated tests for app/(app)/(tabs)/program/literature.tsx
• app/(app)/(tabs)/program/index.tsx coverage via program-index.test.tsx

⚠️ Skipped Tests (2 total):

1. MeetingsScreen suite skipped due to mock setup issues
2. Literature navigation test skipped

✅ Positive Notes:

• 95+ test files covering major functionality
• Good test utilities with renderWithProviders()
• E2E tests with Playwright covering auth, navigation, and features
• Coverage threshold at 85% (statements, functions, lines), 83% branches

4. Documentation Freshness

✅ Up to Date:

• CLAUDE.md accurately reflects current architecture (Expo 54, React Native 0.81, React 19)
• README.md matches current tech stack
• Version in package.json (1.3.0) matches CHANGELOG.md
• CHANGELOG.md has unreleased section tracking current work (Program section)

5. Dependency Health

✅ Dependencies Look Current:

• Using modern versions: React 19.1.0, React Native 0.81.5, Expo 54
• TypeScript 5.9.3 (latest stable)
• Proper pnpm overrides for async-storage compatibility
• No apparent security advisories in main dependencies

Note: Full pnpm outdated check could not be run in this environment

6. Performance Opportunities

⚠️ Memoization Opportunities:

• Components using memo(): 4 (TaskCard, MyTasksView, ManageTasksView, PrayerCard)
• List item components that could benefit from memo:
  • MeetingListItem.tsx - rendered in SectionList
  • MeetingsCalendar.tsx - complex calendar rendering

✅ Good Practices Already in Place:

• useMemo for styles creation in screen components
• useCallback for event handlers
• useFocusEffect for data fetching (prevents unnecessary refetches)
• Proper cleanup patterns in AuthContext with isMountedRef

7. Consistency Check

✅ Excellent Consistency:

• Import organization follows project pattern (React → External → Internal)
• Consistent use of @/ path aliases throughout
• No raw Palette colors in production code (theming properly followed)
• Consistent TypeScript patterns with proper typing

Recommendations

Quick Wins (< 1 hour each)

1. Fix the MeetingsScreen test mock setup to unskip the test suite
2. Add React.memo to MeetingListItem and MeetingsCalendar components
3. Add explicit types to replace any in sentry-privacy.ts

Medium Term

1. Add unit tests for daily.tsx and literature.tsx screens
2. Fix the skipped literature navigation test

No Action Required

• Security posture is excellent
• Documentation is current
• Code style is consistent
• Architecture is sound
