A load-bearing privacy guard runs every fetched body through a regex pre-filter that catches common PII patterns — email, US SSN, credit-card numbers, AU TFN/ABN, E.164 phone — before any write happens. The regex catches 80% of cases at zero LLM cost. An opt-in LLM judge (off by default) handles the harder residual case: a body mentioning a named private individual with no obvious PII pattern. Every decision is recorded in an audit log. This keeps per-row LLM spend off the hot path while still covering the cases the regex misses.
