Control proposition
A card number removed from the chat text can remain visible in a receipt image. Sample the attachment separately.
Proposed protocol
Redacted chats sampled in a defined month, including text, attachments, and bot event logs.
The unit is one chat or handoff event; linked events are recorded separately.
Protocol interpretation
The following statements explain what the proposed controls are designed to preserve. They are not measured outcomes.
Defect rate by data type, location, and redaction method; time to correction; and the share of defects visible to a customer-facing export.
Text filters miss screenshots, pasted receipts, and values split across messages. The defect is often in the attachment or the bot log, not the transcript.
