The change makes Codex auto-discovery skip Remote proxies and bad candidates and continue to later candidates. The production behavior looks sound. Two rejection tests can fail on developer machines that already have Codex installed in a standard system location, so isolate the fixed install roots in those tests before merging.
仅替换 HOME 和 PATH 无法排除这些固定根目录。请将这两个拒绝用例的候选集合限制为临时夹具。安装根目录回退用例继续只使用临时根目录验证。请保留生产代码中的回退，不要为通过旧断言而删除它。

调整调用 resolveOfficialCodexExecutable 的两个拒绝用例，将候选集合隔离到临时测试夹具，避免探测机器上的固定安装根目录；保留安装根目录回退用例对临时根目录的验证，不要修改生产代码中的回退逻辑。

根因
官方 Codex 自动发现只处理首个可执行候选；Remote 安装复制的
bin/codex名称不含 shim/codexhost，未被识别为代理。该候选探测失败或版本过低时，发现流程立即终止，无法继续找到后续真实 Codex。最小改动范围
packages/host-runtime/src/codex-runtime/command.ts与packages/host-runtime/test/codex-runtime-command.test.ts。harnessCandidates、isExecutableFile和现有 Windows native 候选转换，按顺序遍历；对归一化路径用 Set 去重，跳过不可执行、代理、探测失败及低于 0.161.0 的候选。bin/codex检查相邻 format-1 manifest 中匹配的wrapperPath，识别默认及自定义安装目录的 Remote Shim；不把 manifest 的stockCodexPath作为候选来源。stockCodexPath不静默回退、Shim 名称/符号链接拒绝等语义。不修改 Rust、公共契约或包结构。聚焦验证
本地 macOS 上完成以下检查：
npx prettier --check packages/host-runtime/src/codex-runtime/command.ts packages/host-runtime/test/codex-runtime-command.test.ts：通过。npx eslint packages/host-runtime/src/codex-runtime/command.ts packages/host-runtime/test/codex-runtime-command.test.ts：通过。node tools/check-boundaries.mjs：通过。npm run typecheck：通过。npx vitest run --config tests/vitest.config.js packages/host-runtime/test/codex-runtime-command.test.ts：21/21 通过。回归测试在旧实现下先复现 7 个失败；覆盖缺少 stock 环境变量时 Remote 副本真实子进程退出非零、manifest 识别（默认/自定义根目录、残留环境变量）、坏版本/探测失败、重复 PATH 去重、安装根目录回退及不可执行文件。保留既有 Windows native 转换测试；调整通用 fixture 为 native 文件名并固定 PATHEXT，避免大小写造成跨平台断言差异。
当前工作树最初没有依赖，先用锁文件执行
npm ci --no-audit --no-fund并构建 harness-discovery 以准备测试；未修改锁文件。未运行全仓格式检查、全仓 lint 或 Rust 检查；Windows/Linux 实机验证交由 CI。Fixes #864
