- lexer / parser(递归下降)/ evaluate / static-check,四文件纯函数,零 IO 零外部调用 - 子集封顶(ADR-006):比较 · 逻辑 · 算术 · 区间(开闭四态)· 列表与 in · 封闭内建函数集(字符串 / 数字 / 日期);未知函数一律拦下 - 单元格谓词(DMN 一格):`-` 任意 / 比较 / 区间 / 逗号析取 - staticCheck 给「画图即校验」用:语法 + 未知函数 + 引用路径清单 - app 侧以它替下 passthroughEvaluator:监听内容条件真求值,求值异常按不命中处置并留痕 32 个 sfeel 测试;全仓 182 个测试通过,门禁五道全绿 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01KeDBx2PHLavbURXB8LJJ7m
