**Header:** `ClikaRT/graph/pattern.h`

One occurrence of a [`Pattern`](./Pattern.md) in a graph: the matched node per pattern node, in `add_node` order. An optional pattern node absent from this occurrence reads as `std::nullopt`; every other entry holds a node. The nodes are views ([node.h](./index.md#node-h)): they find their nodes again by name after an edit, and once the searched graph is gone they refuse as views whose graph is gone.
