Summary
send_file_to_agentfile paths before storage access.Root cause
The A2A file-delivery path was normalized only after prefixing it with the source Agent ID.
..segments could therefore remove that prefix and resolve to another Agent's stored file.Impact
File delivery now fails closed with
workspace_path_invalidwhenfile_pathcontains..; valid relative paths retain their existing behavior.Validation
