📋 Daily Codebase Review - 2026-02-04

[claude]

Executive Summary

The Sobers codebase maintains good overall health with strong architecture, comprehensive test coverage (~92%), and robust security practices. The primary concerns are: (1) Sentry PII configuration needs adjustment, (2) setTimeout cleanup patterns in a few components, and (3) minor test gaps in the Program section.

Health Score: B+

Justification: Excellent architecture and testing infrastructure, with minor issues in security configuration (sendDefaultPii) and some performance optimization opportunities. No critical bugs or architectural concerns.

---

Top 5 Priority Items

1. 🔒 SECURITY - Change sendDefaultPii: false in Sentry config (lib/sentry.ts:78)
2. ⚡ PERFORMANCE - Fix setTimeout without cleanup in meetings.tsx and SettingsContent.tsx
3. 🧪 TESTING - Add tests for DayDetailSheet, LogMeetingSheet, MeetingListItem components
4. 🧪 TESTING - Fix skipped MeetingsScreen test suite (mock setup issues)
5. 🎨 CONSISTENCY - Replace hardcoded #fff colors with theme.white in 5 component files

Detailed Findings

1. Code Health & Technical Debt

Metric	Status
TODO/FIXME Comments	1 found (meetings.test.tsx:105)
Code Organization	Excellent
File Structure	Well-organized by feature
Large Files	SettingsContent.tsx (2,088 lines) - previously flagged

Existing Issue: #346 tracks SettingsContent.tsx refactoring

2. Security Audit

Check	Result
Hardcoded Secrets	✅ None found
Math.random() for security	✅ Not used
SQL/Command Injection	✅ Protected (parameterized queries)
XSS Vulnerabilities	✅ None found
Input Validation	✅ Proper regex and length checks
PII Handling	⚠️ sendDefaultPii: true should be false

Critical Finding: lib/sentry.ts:78 has sendDefaultPii: true which enables automatic PII collection. The privacy hooks provide mitigation, but this should be set to false as a defense-in-depth measure.

Existing Issue: #348 tracks this

3. Test Coverage Analysis

Category	Coverage	Notes
Components	91.5% (43/47)	Missing: DayDetailSheet, LogMeetingSheet, MeetingListItem, SettingsButton
App Screens	100%	All screens tested
Hooks	100%	All hooks tested
Utilities	88%	Only constants file untested
Contexts	100%	All contexts tested

Skipped Tests:

• meetings.test.tsx - entire suite skipped (mock setup issues)
• program-layout.test.tsx - 1 test skipped (feature hidden)

Existing Issues: #360, #361, #375, #376

4. Documentation Freshness

Document	Status
README.md	✅ Current (mentions 80% coverage, accurate tech stack)
CLAUDE.md	✅ Comprehensive and accurate
Inline Docs	✅ Good coverage of complex logic

Minor: README mentions 80% coverage threshold; actual threshold appears to be enforced in CI.

5. Dependency Health

Check	Result
Security Vulnerabilities	Could not verify (audit command restricted)
Outdated Packages	Could not verify (outdated command restricted)
Unused Dependencies	expo-edge-to-edge potentially unused
Peer Dependencies	✅ All satisfied

Recommendations:

1. Update @sentry/react-native from exact 7.2.0 to ^7.2.0 for patch updates
2. Investigate if expo-edge-to-edge is needed
3. Verify react-native-url-polyfill is still required

6. Performance Opportunities

Issue	Severity	Location
setTimeout without cleanup	HIGH	meetings.tsx:111-121, SettingsContent.tsx:607
Async in useEffect without cleanup	MEDIUM	ThemeContext.tsx:37-52
Sequential queries (suboptimal)	LOW	app/(app)/(tabs)/index.tsx:66-102

Existing Issues: #351, #363

7. Code Consistency

Check	Result
Component Naming	✅ All PascalCase
Import Organization	✅ Consistent pattern
Hook Naming	✅ All use "use" prefix
console.log Usage	✅ None (uses logger)
Theme Colors	⚠️ 5 files use hardcoded #fff

Files with hardcoded colors:

• components/program/DayDetailSheet.tsx
• components/program/LogMeetingSheet.tsx
• components/program/MeetingsCalendar.tsx
• components/whats-new/WhatsNewVersionSection.tsx
• components/whats-new/WhatsNewFeatureCard.tsx
