      description: 'Runs the configured PII detectors (NER and/or pattern tiers) over the supplied text and returns the matched entity spans with the policy action that would fire. Detection only — the text is not modified and no block is enforced. Select detectors explicitly via `detectors`, or pass a consuming `model` to use its effective policy: the model''s own `pii.detectors`, else the instance-wide `pii_default_detectors`. A model with PII disabled, or enabled with nothing to scan with, is a 400. The raw matched value is never returned; admins may set `reveal:true` for the audit hash prefix.'

      description: 'Runs the configured PII detectors over the text and applies each detector model''s policy: masked spans are replaced with `[REDACTED:]`, allow spans pass through, and a single block action causes a 400 (type `pii_blocked`) carrying the offending entities — the text is never returned in that case. Select detectors via `detectors`, or a consuming `model`''s effective policy (its own `pii.detectors`, else the instance-wide `pii_default_detectors`; PII must be enabled on the model). Records audit events (origin `pii_redact`) visible at /api/pii/events.'
