Mainland-China routing

Nested lingtai-update reference. Troubleshooting guidance, not a promise that any mirror is reachable. Before selecting the install flow, install.sh probes https://proxy.golang.org/github.com/golang/go/@latest for three seconds when curl is available and GOPROXY is unset; if that probe fails it exports all three variables below, overwriting existing GOSUMDB or NPM_CONFIG_REGISTRY values:

export GOPROXY="https://goproxy.cn,direct"
export GOSUMDB="sum.golang.google.cn"
export NPM_CONFIG_REGISTRY="https://registry.npmmirror.com"

Release provider and the Python dependency index

install.sh --source auto|github|mirror (or LINGTAI_SOURCE) selects where the release archives, the bundle manifest, and the pinned kernel release come from. auto runs a bounded, fail-open public-IP country lookup and prefers the lingtai.ai download-acceleration mirror for mainland China; any detection or reachability failure falls back to GitHub for the SAME resolved tag/bundle. GitHub remains the sole release/version authority either way — the mirror only re-serves bytes GitHub already published, never its own "latest". (--source gitee is retired: the mirror replaces the earlier Gitee route.) The TUNA dependency-index default is retained from the earlier Gitee path, where an Aliyun-host upgrade failed at third-party dependency resolution through pypi.org. That historical observation is not a live acceptance result for the new lingtai.ai mirror; its production configuration and mainland reachability still require verification.

install.sh now picks exactly one dependency index (python_dependency_index_url):

Situation	Index used for third-party dependencies
non-empty LINGTAI_PYPI_INDEX_URL	that value, on either provider
final bundle provider is the mirror	https://mirrors.tuna.tsinghua.edu.cn/pypi/web/simple
final bundle provider is GitHub	https://pypi.org/simple

"Final" means the provider that actually served the bundle manifest, after any same-tag fallback moved the selection. There is no --extra-index-url: exactly one index is consulted. LingTai itself is never affected — it is always installed from the checksum-verified local artifact by explicit file path and is never requested by package name from any index. Tsinghua TUNA is a cloud-neutral domestic default, not a promise that it is reachable from your host; override it with LINGTAI_PYPI_INDEX_URL when your organization runs its own index.

Scope: this applies to the POSIX verified-bundle path in install.sh. install.ps1 (Windows) and --latest (main-from-source) are unchanged. So is the bootstrap that /update-tui and the Homebrew migration use: they fetch the version-pinned GitHub raw install.sh (tui/internal/config/tui_updater.go:442-465) before any provider selection happens, so that first fetch still needs a working GitHub raw route regardless of which index the installer later chooses.

Homebrew has separate knobs because its superenv can scrub ordinary variables: HOMEBREW_GOPROXY maps to GOPROXY and HOMEBREW_NPM_CONFIG_REGISTRY to NPM_CONFIG_REGISTRY. The formula probes the npm registry with npm ping; a failed probe leaves npm's registry alone. Verify TLS and the actual client (go, npm, or curl) independently, then retry the smallest failing phase.

The Go/npm mirrors above and the dependency-index selection above are separate routes with separate failure modes — diagnose the failing one, not both. Kernel runtime update/nudge behavior after install still belongs to the kernel's system-manual, not to this TUI/portal route.
