| 3 | +
|
| 4 | +Mini App 的分支（packages/expiry-guardian/miniapp/node/server.mjs::decide）： |
| 5 | + 未耗尽 → idle |
| 6 | + 耗尽 + 无积分 + 有卡 → use-card |
| 7 | + 耗尽 + 无积分 + 无卡 → wait |
| 8 | + 耗尽 + 有积分 + 无卡 → keep-credit |
| 9 | + 耗尽 + 都有，卡先过期 → use-card |
| 10 | + 耗尽 + 都有，积分先过期 → keep-credit |
| 11 | +
|
| 12 | +本文件逐条复刻这些分支，任一不一致即视为失败。 |
| 13 | +纯函数测试：不触网、不扣卡。 |
