Records

Default state is read only. Cleanup mode adds delete controls so you can clear test data. It never edits field values.
Delete requires your Firestore security rules to allow write for your account. If a delete is blocked, the page will tell you.
Dead transfers are a daily counter in vendorDailyStats, not per call records. Per call dispute evidence for charged calls lives in consultations.
Window filter is driven by meta.createdAt. Records without a parseable date are excluded from windowed views and appear only under All time.
