## VERTICAL SLICE - NOT FOR PRODUCTION
## 专长（奇物·Feat）定义表 schema：逐 feat_id 行订阅式效果声明的类型化读取（空表合法态；垂直切片验证：订阅行经效果引擎统一解释执行）。
## 🔴 层级纪律：专长只走局内随机渠道（Boss 三选一/凭证开启）——本表行永不入同调位表/局外树。
## triggers 订阅行四词表封闭校验单点在 EffectEngine.validate_trigger_row——本表不自建第二套校验。
## 事件族命名仅系设计侧分组工具：不上数据行、不上卡面。
class_name FeatTable
extends Resource

@export var rows: Array[Variant] = []   # Array[Dictionary] 键 feat_id

## 稀有度词表（四级——与令牌池 TIERS 同名词族；令牌档 = rarity 直映射）
const RARITIES := ["common", "excellent", "rare", "legendary"]

## 行键白名单（🔴 零裸 flat 同族护栏——键出域=加载致命）
const ROW_KEYS := ["feat_id", "display_name", "rarity", "cap", "triggers", "desc", "note"]

## trigger 行键（订阅行三字段：on/when?/do）
const TRIGGER_KEYS := ["on", "when", "do"]
