Read the top-level `shapes` object next — it groups the 65 titles into 18 encodings and names the example that best teaches each one — then open a per-example file, where every `also_solves` entry carries the field-by-field mapping that turns that problem into this example's input.

Only the counts change: both rule families still travel in one request, because a cover chosen first and conflict-checked afterwards is a different and weaker problem. Exactly-once is choose_exactly k=1; at-least-once with per-bundle costs is the cover command; the cheapest exact partition puts per-bundle prices in this command's optional linear objective.
