# Implementation Plan - Fix Recurring Meetings Visibility

## Phase 1: Investigation & Reproduction [checkpoint: 8137d63]
- [x] Task: Create validation test case 6122599
    - [x] Add a test in `icalendar_test.ts` with a valid weekly recurring event starting in the past.
    - [x] Assert that it returns multiple occurrences within the 30-day window.
    - [x] Run the test to see if it fails (confirming the bug).
- [x] Task: Investigate Object RRULE 6122599
    - [x] The logs show `Invalid rrule type (object)`. This means `ts-ics` is parsing RRULE into an object, not a string.
    - [x] Create a test case where `rrule` is an object (mocking `ts-ics` output).
    - [x] Verify that it returns only 1 event (the bug).
- [x] Task: Conductor - User Manual Verification 'Investigation & Reproduction' (Protocol in workflow.md)

## Phase 2: Fix Logic [checkpoint: a4acfa1]
- [x] Task: Support Object RRULE in `expandRecurrences` f7f6028
    - [x] Modify `expandRecurrences` to handle `rrule` as an object.
    - [x] It likely needs to be converted back to a string or used directly if `rrule` library supports it.
    - [x] Run the new test case to confirm the fix.
- [x] Task: Conductor - User Manual Verification 'Fix Logic' (Protocol in workflow.md)

## Phase 3: Cleanup & Verification [checkpoint: 9d07e7a]
- [x] Task: Full Regression Check f1bafb6
    - [x] Run all tests in `icalendar_test.ts`.
- [x] Task: Conductor - User Manual Verification 'Cleanup & Verification' (Protocol in workflow.md)
