"""
Return the data carried by a tool response.
ToolUniverse tools wrap upstream API responses in a ``{"status": ..., "data": ...}``
envelope, so a composition that reads the raw upstream shape straight off the
response always misses and records a populated source as empty. Compose scripts
should unwrap through this helper rather than re-deriving the envelope contract.
Returns None when the call did not succeed, so a source that failed is not
reported as a source that returned nothing.
