In PrivacyGeofence.validate_storage_location, the region detection only checks for EU/APAC substrings and otherwise leaves detected_region as US. That means a path in another region (e.g., a CN bucket name like ...cn...) will be treated as US and allowed whenever US is permitted, which defeats the residency policy for those regions. This is a data-sovereignty bypass that occurs whenever the storage path belongs to an unsupported region but lacks the EU/APAC markers.

DifferentialPrivacyEngine.add_laplace_noise computes scale = sensitivity / self.config.epsilon without validating epsilon. If a caller sets epsilon=0 (a common way to request maximum privacy), this raises ZeroDivisionError and prevents any anonymization from running; negative epsilon also yields an invalid negative scale. A simple validation or minimum epsilon would avoid crashing on those inputs.

P2: Inconsistent use of .get() defaults will produce malformed purl when library dict is missing keys. Lines 176-177 use defaults ("unknown"), but the purl construction does not, resulting in pkg:pypi/None@None instead of pkg:pypi/unknown@unknown.
