• Wikipedia's personal-data page says personally identifiable information is information related to an identifiable person, and that legal definitions differ by place.
• That page quotes NIST SP 800-122: information that can distinguish or trace an identity, and other information that is linked or linkable.
• It says information that might not count as PII under HIPAA can still be personal data under the GDPR. One definition is not universal.
• Replacing a name and leaving a unique account number is not finished. A linked field can still identify.
• This page is not a redaction product and not legal advice.

Masking is a learning habit: find every field that can pick out the person, not only the name. Confirm the definition that applies before you rely on it.

Two fields

1. A toy line: 'Sam, account 4412, asked for a card.'
2. Replace the name. Read the line again.
3. The account number is still there. Mask that too, or say the line is not redacted.
4. Do not use a real customer's line for the exercise.

Redaction

Removing or masking information that can identify a person. A name-only pass can leave a linked identifier.

Sisters: Automatic speech recognition, Sentiment analysis, Quality rubrics, Personal data.

The live voice pipeline answers the person. Analytics reads a recording later. Keep those clocks apart.

A later review can add a rubric you wrote. It cannot borrow a customer's tape.

Config

• Write the goal in one sentence.
• Name the input and the allowed output.
• Save the trace next to the result.

Troubleshooting

• The answer looks fluent and is wrong. Check whether a source passage actually contains the claim.
• The loop never stops. Set a step cap and stop when the tool result repeats.
