# VERTICAL SLICE - NOT FOR PRODUCTION

# Date: 2026-10-04（双层 BD 实施批 T1——标签档位激活引擎）
|
||
# 流派成型判据机制化（整合定稿 设计工具 1——以撒套装/小骨铭文先例）：
|
||
# 同流派标签 relic 计数 ≥2 → 档一（流派核心规则）；≥4 → 档二（完全体）；<2 = 散件（单体保底——
|
||
# 每件效果独立生效，档位只做质变不做启动，反例 B-2）。
|
||
# 纯函数零 await 零 RNG 零副作用（Attunement 求值服务同款纪律）；核心层零特判延伸——引擎只读
|
||
# feat_table 行集与持有集，接线点消费 tiers/hooks 投影。

## 档位求值：feat_ids 持有集 × 行集 → {archetype: tier}（tier ∈ 0/1/2；无行流派不出现）
|

static func tiers_for(feat_ids: Array, table: FeatTable) -> Dictionary:
|

## 挂点投影：持有集 → [{feat_id, hook, archetype, tier, effects}]（表序稳定——同集合同投影，
|

## MC 逐位可复放承载）

## 成型判读（读数面口径）：流派 tier ≥1 = 成型（档一即判——任务书完成定义「标签+档位激活引擎可判成型」）
