// The 自选 golden match covers what it claims (test/golden/README.md, tools/golden.mjs — 0.2.0 自选编队): reads the stored
// digest only (test/golden.test.js recomputes it). Its human seat (AI 托管) slots 推进之王 and prototypes; its shop draws
// its 自选 pieces (and only from the slots' 调度中心 levels), its AI fields 推进之王 — the operator kit — in battle, the
// stock ends where the held copies leave it, and the match ends without errors.
