+ComfyUI saves two formats: the editor ("UI") format with ``nodes``/``links``
+arrays, and the API ("prompt") format ``{node_id: {class_type, inputs}}`` the
+product executes. This module converts UI→API offline and deterministically:
+
+* links are rewritten through ``Reroute`` chains and bypassed (mode 4) nodes;
+* packed subgraph instances (frontend ≥1.x ``definitions.subgraphs``) expand
+  into their inner nodes under qualified ids ``<packed>:<inner>`` — the same
+  scheme ComfyUI itself exports;
+* widget values map through, in priority order: the node's serialized input
+  list (entries carrying a ``widget`` marker — authoritative, this corpus's
+  frontend version always writes them), the ``widgets_values_named`` dict,
+  then a generated registry of widget orders learned from the corpus and the
+  repo's ground-truth API exports (``ui_widget_orders``).
+
+Anything that cannot be mapped with certainty is reported as an issue and the
+file is flagged ``needs_confirmation`` — never silently guessed: a wrong
+widget order produces a runnable-looking workflow with swapped seed/steps,
+which is worse than an honest「需人工确认」.
