# VERTICAL SLICE - NOT FOR PRODUCTION
# 实现 GDD：design/ux/battle.md（B 区结算明细带改造——挖掘期收起 1 行上轮摘要 / 结算期 84px
# 实时流 / 点击展开回看 overlay〔pattern 6 模态纪律〕；行模板「{行为} {值} → {目标}（来源）」、
# 聚合计数行、零值行可见、效果行 value≠pool_value 禁相加、未生效四类行 icon/划线形状冗余、
# highlight 金框〔flag_hit/clear_reward_h2/perfect_broken〕、击杀标记）。
# Date: 2026-09-12（基础 = 2026-09-11 13 类行协议格式化版；2026-09-15 格面资源批 15→10 类：
# 删 item / consumed_ineffective / use_rejected / window_open / window_skip 五类——可选类道具与窗口下线，
# 战斗结算 行协议清单同步；2026-09-16 护甲等级掷点批：伤害行补掷点读数/档位随行标注 + nat20 金框高亮；
# 同日 敌人技能池批：施放行 = 蓄力行 charge 改型〔增益技 0 伤害施放、具名技能〕；
# 2026-09-20 八型批呈现层漏网修复（真人试玩卡断）：伏击退役拆除伤害行 attach 字段后，
# 基线+伏击与普通+穿刺+魔法三分量两拆行分支未同步拆除——敌方行（带 baseline 无 attach）
# 格式化即 Invalid access，结算段中途夭折、界面卡死；两分支随批拆除，行上归因只剩掷点随行）
# 高内聚边界：战斗结算 步骤流 → 玩家文案的全部格式化规则内聚于此；来源文案映射来自 SettlementTable。
