## Frequently asked questions

### What sources does this workflow cover?

It covers raw or mixed text, HTML source, Markdown documents, and line-oriented logs. The extractor should match the source structure rather than treating every input as plain text.

### When is a targeted extractor better than `text-extractor`?

Use the general tool when you are surveying an unfamiliar input or need several common patterns. Use a targeted tool when you need a known field, a defined deduplication rule, or a format-specific syntax check.

### Does this workflow anonymize email addresses, phone numbers, or IP addresses?

No. The listed tools extract candidate values. Authorization, minimization, masking or pseudonymization, access control, retention, and final release review must follow your own handling policy; see the related PII log redaction workflow for a narrower redaction path.
