Summary

remote(dataset_id=...) can be used inside let() DAGs and serializes correctly to JSON for the wire protocol, but local execution raises NotImplementedError("RemoteGraph loading will be implemented in PR 1.3").

This means g.gfql(let({'data': remote(dataset_id='...'), 'filtered': ref('data', [n(...)])})) fails at runtime.

What works

• g.gfql_remote([...]) — sends chains to a remote server (fully implemented)
• remote(dataset_id=...) — AST construction and JSON serialization work
• ASTRemoteGraph.to_json() / .from_json() — round-trips correctly

What doesn't work

• ASTRemoteGraph.__call__() — raises NotImplementedError at graphistry/compute/ast.py:1169
• This blocks local DAG execution when a binding references a remote dataset
