- 新增 chv-guest/chv-data-mount.sh：按 LABEL=CHVDATA 找盘 （不依赖 /dev/vd? 固定名；seed ISO 与根盘排除），无 fs 即 mkfs.ext4 -L CHVDATA，挂到 /home/chv/workspace，幂等； 无数据盘即静默退出 0（copy 模式旧 VM 不报错）。 - build.sh：缺脚本即失败（与 chv-sync.sh 同款门）；拷入 镜像 /usr/local/bin/chv-data-mount；99-chv-sync.cfg runcmd 在 chv-sync boot 之前调它（工作区先挂好再 clone）。 - buildinfo.py BASE_CONTENTS 与两 lockfile DECLARED_SOURCES 登记 chv-data-mount（repo_commit，随 P2 三脚本先例）。 - tests：test_chv_opt_stage1.DataMountScriptTest（脚本内容、 构建接线、lockfile 登记）；P2 干跑夹具补新文件。 回归：discover test_chv_*.py 与 test_cloud_hypervisor.py 全过。 不推、不合、不部署；只本地分支。

"""在构建宿主上生成 CHV 客机镜像的供应链 lockfile。
|
||
|
||
事后校验见 check_lockfile.py（校验 BUILDINFO.versions）；
|
||
本脚本是生成端：读 BUILDINFO.json，以其中的 versions
|
||
（build.sh 已从客机读回的 dpkg-query / pip freeze，
|
||
Playwright=1 时另有 chromium 标识）为唯一版本来源，
|
||
逐项给 contents 清单配版本，写出 lockfile.json：
|
||
|
||
{"tag": ..., "image_sha256": ... | null,
|
||
"generated_at": UTC ISO 时间,
|
||
"versions": {"dpkg": ["name version", ...],
|
||
"pip": ["name version", ...],
|
||
"declared": ["name version", ...]},
|
||
"unresolved": ["查不到版本的名", ...]}
|
||
|
||
版本来源映射（绝不编造版本号，查不到的进 unresolved）：
|
||
- dpkg 包名 → versions.dpkg（"name version" 行）
|
||
- pip 包名 → versions.pip（"name==version" 行）
|
||
- codex / codex-code-mode-host / codex-resources/bwrap
|
||
→ BUILDINFO.codex_version（随 codex 一起发布）
|
||
- /app/host.py → BUILDINFO.repo_commit
|
||
- chromium / chromium-headless-shell → versions.chromium
|
||
（ms-playwright 缓存目录名）
|
||
|
||
注意：旧版逐项查构建宿主的 dpkg/pip，方法不成立——宿主
|
||
版本与客机版本没有必然关系，且 /app/host.py、codex 三件
|
||
套在宿主上永远查不到，--verify 永远过不了。本版只读
|
||
BUILDINFO.versions，不再现场查宿主。
|
||
|
||
用法（均在构建宿主上跑）：
|
||
python3 generate_lockfile.py BUILDINFO.json --output lockfile.json
|
||
python3 generate_lockfile.py --verify lockfile.json \
|
||
--buildinfo BUILDINFO.json
