# VERTICAL SLICE - NOT FOR PRODUCTION
|
||
# Date: 2026-10-01（迭代 10 奖励重构批——level-clear.md v2 三选一选择面承载）
|
||
# 提升三选一覆盖层（模态）：非末关通关的选择停点呈现——部分回血反馈 + 三卡点选 + 确认兑付 +
|
||
# 同调位替换子交互。高内聚边界：文案拼装归 Narrator（组合根喂入），选择意图经信号外发；
|
||
# 视图零核心引用。交互范式 = node_overlay choice_box 按钮族 + 选路两段式（点选→确认）复用，零新原语。
|
||
# 状态机：pick（三卡点选→确认）→ [replace（满位 N+1 选 N）] → result（兑付反馈→继续）。
