///
/// Python attribute names `from_node` / `to_node` conflict with Rust reserved `from`;
/// JSON serialization in `GraphOp.serialize()` uses `"from"` and `"to"` keys.
/// Rust fields use `from_op` / `to_op` with `#[serde(rename = ...)]` to preserve
/// JSON compatibility.
///
/// Python's `type:` field would collide with Rust's `type` keyword, so the Rust
/// field is `kind` (see MIGRATION_rust.md §3a.7).
