|
* 多项目上下文隔离器 (v5.9)
|
|
*
|
|
* 为不同工作目录 (cwd) 提供隔离的状态文件路径，
|
|
* 防止项目 A 的上下文/权重污染项目 B 的路由。
|
|
*
|
|
* 隔离文件:
|
|
* - context-state.json → context-state-{hash}.json
|
|
* - fusion-weights.json → fusion-weights-{hash}.json
|
|
* - route-weights.json → route-weights-{hash}.json
|
|
*
|
|
* 非隔离 (全局共享):
|
|
* - route-feedback.jsonl (全局学习语料)
|
|
* - skill-outcome.jsonl (全局观测)
|
|
* - skills-index.json (技能定义)
|
|
*
|
|
* 用法:
|
|
* const { getIsolatedPath } = require('./project-isolator.js');
|
|
* const stateFile = getIsolatedPath('context-state.json', cwd);
