"""Generates the shared C0 refusal vectors from the pre-Cut 2 v1 store (written before any
variant code existed). Every runtime's tests read the committed bytes; nothing regenerates them
at test time. Run: python generate.py  (needs msgpack).

  unknown-header.msgpack          header cultcache.store.v9, otherwise the v1 store
  extra-slot-full-payload.msgpack v1 header, record item:anvil gains slot 4, payload stays full
  legacy-catalog-extra-slot.msgpack
                                  v1 header, catalog entry in the older layout (contentHash at slot
                                  5), so CultMesh's legacy snapshot reader takes it, plus the

  v1-base.msgpack                 NOT generated here: written once by the Python runtime at CultLib

  variant-v2.msgpack              the wire shape of a variant record, hand-built: header v2, record slot 4 =
                                  [baseKey, overrides[]], empty payload (override op Set = 0, path steps
                                  are [slot, elementId]). C1 does not write this store and refuses to load
                                  it: the variant resolves to its base's name (R6). It exercises readers
                                  that refuse a variant by version or record.
