Generate a pre-signed POST policy for uploading model files to S3.

The returned policy bakes a hard size cap (MAX_MODEL_FILE_BYTES) into the upload — S3 rejects oversized payloads at the edge, so an authenticated researcher cannot use this endpoint to drive arbitrary storage growth.

Parameters:

  • model_id (UUID) – The ID of the model to which the file will be uploaded.

  • body (UploadFileBody) – The request body containing the file name and optionally a Content-Type to lock into the policy.

  • db (Session) – Database session dependency.

  • user_id (UUID) – ID of the authenticated user.

Returns:

url + fields for a multipart/form-data POST plus the maxBytes cap so the client can validate locally.

Return type:

PresignedUploadResponse

Raises:

HTTPException – If the user is not allowed, if the model does not exist or is marked as deleted, or if there is an error generating the policy.
