Implementation Plan - Fix Recurring Meetings Visibility

Phase 1: Investigation & Reproduction [checkpoint: pending]

• Task: Create validation test case 6122599
  • Add a test in icalendar_test.ts with a valid weekly recurring event starting in the past.
  • Assert that it returns multiple occurrences within the 30-day window.
  • Run the test to see if it fails (confirming the bug).
• Task: Investigate Object RRULE 6122599
  • The logs show Invalid rrule type (object). This means ts-ics is parsing RRULE into an object, not a string.
  • Create a test case where rrule is an object (mocking ts-ics output).
  • Verify that it returns only 1 event (the bug).
• Task: Conductor - User Manual Verification 'Investigation & Reproduction' (Protocol in workflow.md)

Phase 2: Fix Logic

• Task: Support Object RRULE in expandRecurrences
  • Modify expandRecurrences to handle rrule as an object.
  • It likely needs to be converted back to a string or used directly if rrule library supports it.
  • Run the new test case to confirm the fix.
• Task: Conductor - User Manual Verification 'Fix Logic' (Protocol in workflow.md)

Phase 3: Cleanup & Verification

• Task: Full Regression Check
  • Run all tests in icalendar_test.ts.
• Task: Conductor - User Manual Verification 'Cleanup & Verification' (Protocol in workflow.md)
