    <thetext>In WKDigitalCredentialsPicker.mm handleNSError: method, two error mappings need to be updated to align with the Digital Credentials spec:

1. WKIdentityDocumentPresentmentErrorCancelled currently maps to AbortError. Since platform-level cancellation is distinct from user-initiated abort (via AbortSignal) and user-initiated cancel (via the chooser UI), it should fall through to OperationError instead. The spec reserves AbortError for the two user/caller-driven cases only.

2. The default/unknown case currently maps to UnknownError. Per the WebIDL spec, UnknownError is defined as &quot;the operation failed for an unknown transient reason (e.g. out of memory)&quot; -- that does not fit a platform error with an unrecognised code. OperationError (&quot;the operation failed for an operation-specific reason&quot;) is the correct modern catch-all.

Changes needed in handleNSError::
- Remove the WKIdentityDocumentPresentmentErrorCancelled case (let it fall through to default)
- Change default case from ExceptionCode::UnknownError to ExceptionCode::OperationError</thetext>
