- 变更规模：新增 514 / 修改 62 / 重命名 155 / 删除 4（归档重组与文档轮次） - .gitignore 修：`归档/**/db-cwd归一-备份-*/` —— 原规则写绝对层级（归档/db-cwd归一-…）， 目录搬进 归档/配置与备份/ 后**静默失效**，43 MB 的 DB 备份又变成未跟踪 - .gitignore 补：嵌套 git 内部数据（归档/内嵌git-20261008/、归档/skills-git-旧线-20261007/dotgit-原样移出/） - .gitignore 补：运行态与部署副本（.workbuddy/collab/、.workbuddy/tools/、.workbuddy/.load-pending、.workbuddy/tmp-*） - .gitignore 补：备份件（*.bak-*） - 未跟踪文件从 2190 降到 890（其余为 归档/ 归档件与 .workbuddy/memory/ 知识文件，按口径入库）

* session-gc.cjs —— 会话记录保留期回收（档案 14 §H3 / 档案 28）
|
||
* 规则（用户 2026-09-11 定）：**每个用户的 sessions 达到阈值才触发**，清理 **超过 N 天** 的会话目录。
|
||
* 结构：<home>/sessions/<workspace-slug>/<session-id>/session.jsonl.zstd
|
||
* 安全：默认 dry-run；--apply 时 `mv` 到 <userRoot>/trash/<日期>-session-gc/（保留 30 天）。
|
||
* 说明：storages/session_projcache 体积很小（KB 级），本脚本不动它（留作后续细化）。
|
||
*
|
||
* 用法：node session-gc.cjs [--apply] [--threshold 500] [--days 90] [--user-id <uuid>]
