从 TRM4 core/harness/eprocess.py 逐行迁移，零逻辑变更: - compute_e_value: 截断 Beta 混合 e 值（log 空间 + betainc 对称性） - gate_decision: 四出口优先级链（confirmed→directional→futility→exhaustion→continue） - probation_verdict: 试用期非对称双向结算 - 常量保真: _WALD_WIN=ln1.4, _WALD_LOSS=ln0.6, _SHRINK_PSEUDO=4 仅变更: import 路径 + GateParams/GateVerdict 移至 types.py + 中文 docstring 14 tests 覆盖: e 值数学、边界校验、四出口路径、试用期三分支 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
