现有 observe=0 仍运行 allocator 包装,不能区分字素成本与观测成本。本改动为 Rust 测量程序增加编译期不定义包装器的模式,默认行为保留;结果与 validator 显式区分包装身份、投影与未知分配指标,并冻结负载/hash/顺序/统计及预算决定程序。

Release/locked/offline 两模式实际构建,13项准备测试通过(内部8次短 sanity,无skip);补跑原 measurement 套件9/9。独立 Standards/Spec 审查均无阻断发现。源码/产物/日志身份见 experiments/measure/results/2026-10-26-r54-preparation/validation.json。

这不是正式性能采样或整体无插桩结论;旧12样本不改,.3/.4共同harness、受控批次、归因与数值预算仍待完成,#54继续开放。Refs #54, #34.
