-        `source` is one of three shapes (`AnthropicMessagesImageParam.source`):

-        base64 is returned as a data URI rather than the bare payload: consumers of
-        ``GenericGuardrailAPIInputs["images"]`` otherwise have no way to know the
-        format, and an API like Bedrock's ApplyGuardrail requires it. url is passed
-        through so the consumer can fetch it under its own SSRF policy.
-
-        file is not resolvable here (the bytes live behind the Files API), so it
-        yields nothing. That is a silent gap for any consumer that treats a missing
-        entry as "no image to scan"; scanning a file_id needs a fetch this extractor
-        has no client for.
