Control proposition
Redaction settings are not evidence; a transcript-level check across text, attachments, and unredacted copies is required to show that sensitive data was removed.
Proposed protocol
List the sensitive data classes and their patterns, including payment cards, bank accounts, government identifiers, health data, and authentication secrets.
Draw a sample across channels, queues, shifts, attachments, transfers, and bot sessions. Record the query date, filters, and exclusions.
Open each record and search for the patterns in the text, metadata, and attachments. Check the original copy as well as the redacted view when both exist.
Record the data class, location, source, and whether the exposure was agent-supplied, customer-supplied, or tool-generated.
Confirm who can access unredacted records and whether access is time-bound to the investigation or role.
Group findings by cause and assign a source fix, then retest the same sample frame after the repair.
Protocol interpretation
The following statements explain what the proposed controls are designed to preserve. They are not measured outcomes.
Attachment and screenshot paths often bypass text-only redaction rules.
Pasted customer text can carry formatting that defeats a simple pattern match.
An enabled setting does not prove that a specific record was cleaned.
Access to the original record is part of the exposure even when the redacted view is correct.
Recurring leaks from one macro or integration need a source repair rather than repeated training.
A post-repair sample must use the same frame to show whether the exposure rate actually changed.
