feat(cheap-worker): M3b 本机 U1-U3 — 9d trace parity 救活 D11 + D9 vendored + 跨语言反假绿门(切片一 M3b)
便宜档生成切到 cheap-worker 新路后,result_out 只产 trace.cost、缺 9d trace 七项,致后端 D11 ReadinessScorer 三维恒中性、退化成 45/55 双峰近恒定分,D9 反同质失效。
U1 cheap_studio 富化:build_trace_source + _furthest_stage,additive 捕获 verdictFull/driverType/models/stage。U2 result_out._build_trace:七项(repairs=max(0,attempts-1))+ sevenGateVerdict{pass,guards} + gatespec{driver} + cost + similarity,camelCase 镜像 _extract_trace、None 容错。U3 D9 dedup vendored 进 cheap-worker/dedup.py(registry 指自己 results/)、worker_service 接线非阻断。
Java 跨语言切片测加逐维反假绿门(反射调真 ReadinessScorer:三维脱离中性 + 合成分 100 vs 退化 ≤55 拉开 ≥35)。顺带修预存 M3a 红测:worker 异常兜底 failureReason 改传真枚举 llm_error。
验证:cheap-worker 全 16 测绿 + Java 切片 5/5 绿 BUILD SUCCESS。范围仅 cheap-worker/ + 2 fixture + 1 Java 测 + plan,零 live 触碰。
