## Phase 3: Calendar Integration - Final Comprehensive Review

### Summary of Findings

After comprehensive analysis, the Phase 3 plans (03-01, 03-02, 03-03) for Calendar Integration have several issues that need to be addressed:

### Issues Found:

## 1. Requirement Coverage - Incomplete Coverage for CAL-03

**Problem**: The requirement "User can view calendar events alongside tasks in weekly view" (CAL-03) is not fully addressed in the plan structure.

**Analysis**:
- CAL-01: Covered in Plan 03-01 (Google/Apple OAuth)
- CAL-02: Covered in Plan 03-01 (Google/Apple OAuth)  
- CAL-03: Partially covered in Plan 03-03 (viewing in weekly view) but not explicitly tied to the OAuth implementation in Plan 01
- CAL-04: Covered in Plan 03-02 (sync functionality)

**Issue**: The connection between OAuth connection (Plan 01) and actual display in weekly view (Plan 03) is not clearly spelled out in the planning.

## 2. Structural Discrepancy - Plan Count Mismatch

**Problem**: Roadmap specifies 2 plans for Phase 3 but 3 plans exist.

**Analysis**:
- Roadmap: "Plans: 2 plans" 
- Actual: Plans 03-01, 03-02, 03-03 exist

This creates an inconsistency that makes it difficult to understand the intended scope and boundaries.

## 3. Missing Explicit Linkage Between Plans

**Problem**: There's no explicit task that establishes the connection between OAuth implementation and calendar display.

**Analysis**: 
- Plan 03-01: Implements OAuth flows for Google and Apple calendars
- Plan 03-02: Implements synchronization logic
- Plan 03-03: Implements display of calendar events in weekly view

But there's no plan that explicitly ties these components together.

## 4. Task Completeness - Missing Implementation Details

**Problem**: While all tasks have Files, Action, Verify, and Done fields, some action descriptions could be more specific about how the key links are implemented.

**Analysis**:
- Most tasks have good descriptions
- Some could better explain how they interact with other modules

### Recommendations:

1. **Consolidate Plans**: Either reduce to 2 plans as specified in roadmap or update roadmap to reflect 3 plans
2. **Improve Inter-Plan Linking**: Create a plan that explicitly addresses the integration between OAuth, sync, and display functionality
3. **Clarify CAL-03 Coverage**: Make it explicit how the calendar events display connects to the OAuth connection

## Verification Status: ISSUES FOUND

**Phase:** 03-calendar-integration
**Plans checked:** 3 
**Issues:** 1 blocker(s), 2 warning(s), 0 info

### Blockers (must fix)
1. [requirement_coverage] CAL-03 requirement (view events in weekly view) lacks explicit connection to OAuth implementation from Plan 01
2. [scope_sanity] Roadmap specifies 2 plans for Phase 3 but 3 plans exist, creating inconsistent planning structure

### Warnings (should fix)
1. [requirement_coverage] The requirement for viewing calendar events alongside tasks (CAL-03) is primarily addressed in Plan 03-03 but not explicitly tied to the OAuth implementation from Plan 01
2. [task_completeness] Some action descriptions could better document the implementation of key links between modules

### Structured Issues

```yaml
issues:
  - plan: null
    dimension: requirement_coverage
    severity: blocker
    description: CAL-03 requirement (view events in weekly view) lacks explicit connection to OAuth implementation from Plan 01
    fix_hint: Clarify how the calendar connection (Plan 01) integrates with the display functionality (Plan 03-03)

  - plan: null
    dimension: scope_sanity
    severity: blocker
    description: Roadmap specifies 2 plans for Phase 3 but 3 plans exist, creating inconsistent planning structure
    fix_hint: Either consolidate the plans to match the roadmap or update roadmap to reflect 3 plans

  - plan: "03-03"
    dimension: requirement_coverage
    severity: warning
    description: Requirement for viewing calendar events alongside tasks isn't explicitly tied to OAuth connection
    fix_hint: Clarify how calendar events display connects to the OAuth implementation from Plan 01

  - plan: "03-01"
    dimension: task_completeness
    severity: warning
    description: Action description doesn't explicitly mention implementation of key links with other modules
    fix_hint: Expand action description to state how OAuth flow connects with other calendar modules and the backend
```

## Conclusion

The Phase 3 plans demonstrate good structural organization but have significant issues in alignment with the roadmap specification and requirement coverage. The core problem is in the plan count mismatch and the lack of explicit integration planning between the OAuth implementation and calendar display functionality. These issues should be addressed before proceeding with execution.
