CRITICAL BUG FIX: - Phase boundaries were hardcoded for 31-day cycle, breaking correct phase calculations for users with different cycle lengths (28, 35, etc.) - Added getPhaseBoundaries(cycleLength) function in cycle.ts - Updated getPhase() to accept cycleLength parameter (default 31) - Updated all callers (API routes, components) to pass cycleLength - Added 13 new tests for phase boundaries with 28, 31, and 35-day cycles ICS IMPROVEMENTS: - Fixed emojis to match calendar.md spec: 🩸🌱🌸🌙🌑 - Added CATEGORIES field for calendar app colors per spec: MENSTRUAL=Red, FOLLICULAR=Green, OVULATION=Pink, EARLY_LUTEAL=Yellow, LATE_LUTEAL=Orange - Added 5 new tests for CATEGORIES Updated IMPLEMENTATION_PLAN.md with discovered issues and test counts. 825 tests passing (up from 807) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
