XFD: Safe House detectors tightened across prompt injection and PII leak classes.
CFD and CBD detector families got a calibration pass. Fewer false positives on benign tool calls, sharper block rate on novel injection patterns — without expanding the data we collect.
- Prompt-injection detectors retrained against fresh adversarial corpus; 12% fewer false positives.
- CBD now catches split-token PII leaks (e.g. SSN or card numbers broken across streamed chunks).
- Signed verdict format now includes detector version, so auditors can reproduce the exact classifier used.
