## ❌ CRITICAL ISSUES FOUND

### 🔴 BUG #1: Issue/Task Creation Fails

**Status**: NEW BUG (discovered during regression testing)
**Severity**: CRITICAL - Blocks all issue/task creation
**Error**: `Linear GraphQL validation error: Argument Validation Error`

**Root Cause**: Same bug as 1M-552 but in `_create_task()` method. The fix was only applied to epic creation.

**Fix Required**: Add team_id validation to `_create_task()` method (line 1494)

```python
team_id = await self._ensure_team_id()

# Add this validation:
if not team_id:
    raise ValueError(
        "Cannot create Linear issue without team_id. "
        "Ensure LINEAR_TEAM_KEY is configured correctly."
    )
```

### 🔴 BUG #2: Epic Listing Fails

**Status**: REGRESSION (1M-553 fix incomplete)
**Severity**: CRITICAL - Breaks epic management UI
**Error**: `Field "teams" is not defined by type "ProjectFilter"`

**Root Cause**: GraphQL query uses invalid `teams` filter field. Linear's `ProjectFilter` schema doesn't support this field.

**Investigation Needed**:
1. Review Linear's current ProjectFilter schema
2. Update filter to use valid fields (`lead`, `name`, or `needs`)
3. Find correct approach for team-scoped project filtering

## ✅ WORKING OPERATIONS

- ✅ Epic creation (1M-552 fix verified)
- ✅ Epic retrieval by ID
- ✅ Ticket search
- ✅ Configuration management
- ✅ API connectivity

---

## 🚨 RELEASE RECOMMENDATION

**⚠️ DO NOT RELEASE** - Two critical blockers must be fixed first:

1. Issue/Task creation completely broken
2. Epic listing broken

**After Fixes**:
- Apply issue creation fix (same pattern as epic fix)
- Fix epic listing GraphQL filter
- Re-run full QA test suite
- Then proceed with release
