Four behaviour tests guarding the controller's contract with the rest of the editor: - openFlow seeds the graph + clears the dirty flag against the freshly-captured baseline. - graph edits re-emit YAML into the shared CodeController so the text tab stays in lockstep. - graph edits mark the buffer dirty against the baseline; markSaved snaps it back to clean. - selectStep is idempotent: re-selecting the same step doesn't notify listeners (cheap rebuild guard for the properties panel). 11/11 tests pass.

// Behaviour tests for FlowEditorController — the bridge
|
|
// between the YAML buffer + the graph + the layout sidecar.
|
|
// The model tests cover parsing correctness; these cover
|
|
// that the controller wires text -> graph reparsing,
|
|
// graph -> YAML emission, selection bookkeeping, and
|
|
// dirty/saved transitions correctly.
