+# Semantic Release 版本迁移跟踪
+
+## 目标
+
+将版本管理从固定 `patch + 1` 的自动打 tag 迁移到 `semantic-release`，同时保留现有 `.github/workflows/publish.yml`
+的 tag 触发打包、NuGet 发布、GitHub Packages 发布和 GitHub Release 流程。
+
+- 用 `cycjimmy/semantic-release-action` 替换 `auto-tag.yml` 的版本判断和打 tag 逻辑
+- 保留 `publish.yml` 的现有发布实现，不重写 NuGet 流程
+- 避免 `semantic-release` 与 `publish.yml` 重复创建 GitHub Release
+- 将版本规则固定为 `feat -> minor`、`fix/perf/refactor -> patch`、`BREAKING CHANGE` 或 `! -> major`
+- 为手动 `workflow_dispatch` 保留 dry-run 验证入口，先验证最近提交会算出什么版本
+
+## 当前恢复点
+
+- 恢复点编号：`SEMREL-RP-001`
+- 当前阶段：`Phase 1`
+- 当前焦点：
+  - 增加 `.releaserc.json`，仅启用版本分析与 release notes 生成，不启用 GitHub Release 发布插件
+  - 将 `auto-tag.yml` 改成 `workflow_run` 真正打 tag、`workflow_dispatch` 只做 dry-run 的双入口
+  - 明确 `PAT_TOKEN` 与 `GITHUB_TOKEN` 的职责边界，确保 tag 继续触发 `publish.yml`
+
+### 已知风险
+
+- `GITHUB_TOKEN` 推送 tag 不会再触发另一个 workflow，真实发布仍需要 `PAT_TOKEN`
+- `semantic-release` 的版本判断完全依赖 Conventional Commits；不规范提交会直接影响版本计算
+- 当前仓库本地 `dotnet clean/build` 仍受 WSL fallback NuGet 路径影响，验证时需要继续采用已知可用的直接构建命令
+
+## 已完成
+
+- 已确认当前版本入口为 `.github/workflows/auto-tag.yml`，现状始终执行 `PATCH + 1`
+- 已确认当前 `.github/workflows/publish.yml` 由 tag 触发，并负责 `.nupkg` 打包、发布和 GitHub Release
+- 已确认最新 tag 为 `v0.0.222`
+- 已确认 `v0.0.222..HEAD` 之间存在 `feat(...)` 提交，按目标规则首次 dry-run 预期版本应为 `v0.1.0`
+- 已新增 `.releaserc.json`，仅保留 `@semantic-release/commit-analyzer` 与
+  `@semantic-release/release-notes-generator`，避免 `semantic-release` 直接创建 GitHub Release
+- 已将 `.github/workflows/auto-tag.yml` 重写为：
+  - `workflow_run` 在 `main` 上、CI 成功且提交消息包含 `[release ci]` 时执行真实打 tag
+  - `workflow_dispatch` 只执行 dry-run，输出 `last_tag`、`next_version` 与 `next_tag`
+- 已明确真实打 tag 仍使用 `PAT_TOKEN`，因为 `GITHUB_TOKEN` 推送的 tag 不会继续触发 `publish.yml`
+
+## 验证
+
+- `git describe --tags --abbrev=0`
+  - 结果：通过
+  - 备注：当前最新 tag 为 `v0.0.222`
+- `git log --pretty=format:%h%x09%s v0.0.222..HEAD`
+  - 结果：通过
+  - 备注：最近版本窗口内存在多条 `feat(...)`，后续 dry-run 预期应提升 `minor`
+- `dotnet build GFramework.Core.Abstractions/GFramework.Core.Abstractions.csproj -c Release -p:RestoreFallbackFolders=`
+  - 结果：通过
+  - 备注：`GFramework.Core.Abstractions` 与 `GFramework.Cqrs.Abstractions` Release 构建通过，`0 warning / 0 error`
+- `npx --yes semantic-release --dry-run --no-ci`
+  - 结果：受阻
+  - 备注：当前工作树的本地 tag 历史在 `git fetch --tags` 阶段出现 `would clobber existing tag` 冲突，不能直接作为 dry-run 环境
+- `git clone --branch main --single-branch git@github.com:GeWuYou/GFramework.git /tmp/gframework-semrel-dryrun`
+  - 结果：通过
+  - 备注：已建立干净临时克隆用于 dry-run 验证
+- `npx --yes semantic-release --dry-run --no-ci`（在 `/tmp/gframework-semrel-dryrun`）
+  - 结果：通过
+  - 备注：dry-run 成功识别 `v0.0.222` 为最新 release，并分析 `269` 个提交；按当前规则会提升到下一次 `minor` 发布，预期 tag 为 `v0.1.0`
+
+## 下一步
+
+1. 复核 `workflow_dispatch` dry-run 输出格式是否还需要额外收窄或增加说明
+2. 评估是否要把 `workflow_run` 的 `[release ci]` 门闸改成更显式的 PR label 或 manual approval
+3. 若本轮验证通过，按仓库要求创建提交并等待你审阅发版流程细节

+# Semantic Release 版本迁移追踪
+
+## 2026-04-26
+
+### 阶段：方案落地准备（SEMREL-RP-001）
+
+- 读取当前 `auto-tag.yml` 与 `publish.yml`，确认最小侵入改法应只替换版本判断与打 tag，保留 tag 触发发布链
+- 核对最近 tag 与提交历史：
+  - 最新 tag 为 `v0.0.222`
+  - `v0.0.222..HEAD` 含多条 `feat(...)`，按目标规则首次 dry-run 预期结果为 `v0.1.0`
+- 补建本主题的 active tracking / trace 入口，并在 `ai-plan/public/README.md` 中为
+  `feat/semantic-release-versioning` 建立 worktree 映射
+
+### 阶段：配置落地与验证（SEMREL-RP-001）
+
+- 新增 `.releaserc.json`，显式固定：
+  - `feat -> minor`
+  - `fix/perf/refactor -> patch`
+  - `docs/test/chore/build/ci/style -> no release`
+  - `BREAKING CHANGE` / `BREAKING CHANGES` 作为 major 信号
+- 重写 `auto-tag.yml`：
+  - 保留 `workflow_run` 监听 `CI - Build & Test`
+  - `workflow_dispatch` 变为 dry-run 入口
+  - 真实打 tag 改由 `semantic-release-action` 处理，并要求 `PAT_TOKEN`
+- 完成最小构建验证：
+  - `dotnet build GFramework.Core.Abstractions/GFramework.Core.Abstractions.csproj -c Release -p:RestoreFallbackFolders=`
+  - 结果：通过，`0 warning / 0 error`
+- 直接在当前工作树执行 `semantic-release --dry-run` 时命中本地 tag 抓取冲突：
+  - `git fetch --tags ... would clobber existing tag`
+  - 结论：当前工作树不适合作为 dry-run 验证环境
+- 改用干净临时克隆 `/tmp/gframework-semrel-dryrun` 再跑 dry-run：
+  - 成功识别 `v0.0.222` 为最新 release
+  - 成功分析 `269` 个提交
+  - 按当前规则得出下一次应为 `minor` 发布，预期版本窗口从 `0.0.222` 提升到 `0.1.0`
+
+### 下一步
+
+1. 复核变更 diff 并创建提交
+2. 向用户说明新的发版链路与可优化点
