DVAgreementRecordError: An acceptance that could not be written, and so was not given.
DVAIOpsError: A declaration the AI operations layer refuses, carrying its diagnostic code (DV-AIOPS-005, DV-AIOPS-006).

DVAnalyticsConfigurationError: A provider configured in a way consent cannot govern.
DVApiKeyNotLive: Rotation asked of a key that is revoked, expired, gone or already rotated.

DVCacheConfigException: A dartvel.cache block Dartvel cannot honour, found by the build.
DVCaptureBusy: Another recording already holds the device.

DVCapturePermissionRefused: The person refused a capture permission.
DVCaptureUnsupported: The target cannot record what was asked for.
DVCaptureWriteError: A captured change could not be written to the log, so the write it recorded was undone rather than kept uncaptured.
