check_changelog.py：正式版本条目必须四节齐备且非空（改了什么/兼容性与迁移影响/怎么验收/已知问题）、版本号三段无前导零、[Unreleased] 在最上面；新增 --tags 核对正式 tag（必须注释 tag）与它指到那个提交里的版本记录一致。只有 Unreleased 的新工程放行；没有正式 tag 不判红（开发版本不打 tag 是常态）。ci_checks.py：新增必需检查 version（门禁 15 项），策略版本 ci-checks/2。ci_checkout.sh：记录远端 tag 清单并取 tag 对象供核对。release_preflight.py：只读预检（版本建议/完整 SHA/CI 证据/CHANGELOG/远端 tag 与 Release/遗留项），写类 git 命令与 POST 在预检路径上被拒（--self-test 证明）；批准后 --execute 才打注释 tag、推 tag、建 Release 并读回。CHANGELOG 0.1.0 补上原本缺的两节。

"""发版预检 —— **只读**，把"要不要发、发什么、有没有证据"一次列清楚。
|
||
|
||
设计上的三条硬规矩：
|
||
1. **预检不产生任何副作用**：只走白名单里的只读命令（`git ls-remote/rev-parse/log/show/…`、
|
||
HTTP GET）。`_git_read()` / `_api_read()` 会**拒绝**任何写操作 —— 这条有自检
|
||
（`--self-test` 断言"写命令与 POST 在预检路径上被拒"）。
|
||
2. **正式 tag / Release 只在显式批准后执行**：`--execute --approve-version X.Y.Z --approve-sha <完整40位>`
|
||
三个都给齐、且预检没有阻塞项，才会 `git tag -a` + `git push <tag>` + 建 Release；
|
||
执行后**读回**（远端 tag SHA == 本地打的那个提交、Release 的 tag_name/version 一致）才算成功。
|
||
3. **拿不到证据就说拿不到**：没有凭据、查不到 CI 状态时打印"未核对"，不写成"已通过"。
|
||
|
||
用法：
|
||
python3 scripts/release_preflight.py # 建议 patch（默认）
|
||
python3 scripts/release_preflight.py --bump minor
|
||
python3 scripts/release_preflight.py --version 0.2.0
|
||
python3 scripts/release_preflight.py --self-test # 只读保证的自检
|
||
# 批准后才执行（本轮不执行）：
|
||
python3 scripts/release_preflight.py --execute --approve-version 0.2.0 --approve-sha <完整SHA>
