"""E1 token 经济学实验脚本（论文主实验，本地确定性可跑）。
|
||||
|
||||
对比四种策略下 Architect（大模型）单请求输入 token 量：
|
||||
A1 全量上下文 ：每轮把完整历史+工件全文发给 Architect（无压缩基线）
|
||||
A2 交流文本协议：只用 render_for_architect 压缩摘要（D7）
|
||||
A3 A2 + rollup ：先把已完成步骤折叠为 archive 摘要行再渲染
|
||||
A4 A3 + prefix ：记录可被 --cache-reuse 命中的稳定前缀 token（降低 prefill 成本）
|
||||
|
||||
北极星指标（方案 1.0）：A2/A3/A4 相对 A1 的 token 下降 ≥80%。
|
||||
|
||||
用法：
|
||||
python scripts/bench_tokens.py [--data eval/v2_sample.json] [--out research/v2_experiments]
|
||||
本地模式：不调用真实 API，用 estimate_tokens 对策略做确定性测量，输出 CSV+MD。
|
||||
--live 模式（可选，需 API key + 本地模型）：走真实管线记录 usage。
