- systemd-networkd（/usr/lib 80-container-ve.network，匹配 ve-*） 会在 veth 建好后几秒内刷掉静态 10.200.0.1、改 DHCP/链路本地， 致单元网关不可达、TCP/UDP 全灭（FORWARD/NAT 计数器恒 0； 早先一次 curl 403 是刷掉前的窗口期偶发）。修法：镜像内置 /etc/systemd/network/79-chv-cell.network（Unmanaged=yes）， 须排在 80 之前（99 会被 80 抢走，已实测）；build.sh copy-in + 校验、BASE_CONTENTS 与两处 DECLARED_SOURCES 登记。 - run_cell 配网后复核 ve 上确有 10.200.0.1（_iface_has_ip）， 不见即大声失败、不跑无网单元（第二道防线）。 - 单元内 DNS：/etc/resolv.conf 是 127.0.0.53 stub，单元独立 netns 里自己的 lo 上没有 resolver；把上游 /run/systemd/resolve/resolv.conf 绑到 /etc/resolv.conf （解析 symlink 后挂真实目标）。live 验证：DNS-UDP-OK、 getaddrinfo 解析成功、curl https://gitea.tose.top 200。 - 单测：CellResolvTest + _iface_has_ip 真实 lo 断言 + 规约 dns_resolv_conf 字段；P2 + 阶段 2 共 74 项全过。

"""生成 CHV 客机镜像的 BUILDINFO.json（build.sh 调用）。
|
||
|

从 build.sh 抽出（B-02），使其可独立单元测试。输入全部是

已落盘的构建产物与读回文件，不编造版本号：versions 来自
|
||
客机读回的 dpkg-query / pip freeze（Playwright=1 时另有
|

ms-playwright 缓存目录名作 chromium 标识）；artifacts 的
|

sha256/size 是对产物文件实测的；image_sha256 即 disk.raw
|

的 sha256，供 generate_lockfile.py 沿用。

用法：

python3 buildinfo.py OUT_DIR TAG UBUNTU CODEX_VERSION \\

CHROMIUM_HEADLESS_SHELL_REV（可选，纯数字）：钉死的

ms-playwright 缓存修订号（如 1248）。PLAYWRIGHT=1 且
|

给了该值时，versions.chromium 里须恰好出现
|
||
chromium_headless_shell-<rev>，否则退出 1、构建失败；
|
||
未给时只记录、不强制，BUILDINFO.chromium_pinned_rev
|

记 null，构建输出由 build.sh 明说“未钉死”。
