### Overview

- **Login:** ${results.login}
- **Bills Created:** ${results.billsCreated}
- **Final Result:** ${results.finalSummary}

### Notes Feature Test Results
- **Per-Bill Per-Month:** ${results.notesFeature.perBillPerMonth}
- **Persistence:** ${results.notesFeature.persistence}
- **Month Switching:** ${results.notesFeature.monthSwitching}

### Other Features Test Results
- **Bill Creation:** ${results.otherFeatures.billCreation}
- **Autopay Toggle:** ${results.otherFeatures.autopayToggle}
- **Two-Factor Toggle:** ${results.otherFeatures.twoFactorToggle}
- **Payment Tracking:** ${results.otherFeatures.paymentTracking}
- **Bill Edits:** ${results.otherFeatures.billEdits}

### Bugs Found
${
  results.notesFeature.issues.length > 0 || results.otherFeatures.issues.length > 0
    ? results.notesFeature.issues.map(i => `- ${i}`).join('\n') + 
      (results.notesFeature.issues.length > 0 && results.otherFeatures.issues.length > 0 ? '\n' : '') +
      results.otherFeatures.issues.map(i => `- ${i}`).join('\n')
    : 'None'
}

### Notes Feature Status
The notes feature is implemented as **per-bill AND per-month**. Each bill has its own notes field, and each month has its own separate notes. This means:
- Bill A January notes ≠ Bill B January notes
- Bill A January notes ≠ Bill A February notes
- All bills on the Tracker page have editable notes for the current month
