从官方 Git 仓库导入 chandra447/pi-hermes-memory 在 tag v0.9.10 （df624056a2e8c68bc89ba0a81e1c120856ec9665，2026-10-02）的源码快照。 本次仅导入源码，尚未接入组合包：package.json、加载顺序、依赖与权限策略 均未改动。 - 原样导入 src/、tests/、docs/、scripts/、README、CHANGELOG、PLAN、 AGENTS 与 LICENSE；该快照共 156 个上游文件。 - 剔除嵌套 .git、上游 .github 工作流、.ralph/、.claude/、node_modules、 覆盖率与构建产物。 - 新增中文 UPSTREAM.md，记录来源，以及启用前必须完成的待决事项： 在 pi-compaction 之前注册加载顺序、better-sqlite3 版本与根 allowScripts 对齐、strip-ansi 解析确认。 - 说明选择 tag 而非 main 的原因：导入时上游 main 已领先至 24fcd8ad26fc27badb8d7dbaf8034645de07b893（2026-10-11），选 tag 是为 对应一个已发布、可复现的版本。 尚未接线。启用前还需反转 tests/extension-load.test.ts 中"不得加载 Hermes"的断言，并同步 pi-tool-search 分组、权限策略与文档。 验证：快照 156 个上游文件全部导入，目录内仅多出 UPSTREAM.md 一份； 已确认与上游 main 内容存在差异，证明取的是 tag 而非 main。
