-每次推送到 `main` 会触发 `.github/workflows/publish.yml`，自动构建并发布 **post 预发布版本**（仅供 CI 流水线内部使用，**不是**正式版本线）。
+- jiangchang-platform-kit **只发布正式版本**。
-
+- 每次需要发布公共能力时，先 bump `pyproject.toml` 的 `version`（例如 `1.0.10` → `1.0.11`）。
-正式版本线使用 **1.0.x** semver，通过 git tag 发布。
+- 推送 `main` 后，`.github/workflows/publish.yml` 会构建并上传该正式版本到 Gitea PyPI。
+- 发布包版本必须等于 `pyproject.toml` 中的 `version`；若该版本已存在，上传会失败，需继续 bump 版本号后再推送。

 git push origin main

   - 加密 scripts/（递归 PyArmor -r，输出到包内 scripts/，与源码目录树一致）
   - 复制 SKILL.md
