🟠 High provider/providerMaintenance.ts:434

For an unrecognized Codex executable, fallback returns native and exposes a one-click update with env: { CODEX_HOME: sharedHomePath }. makeCodexMaintenanceResolver therefore updates the shared CODEX_HOME installation instead of the configured binary, leaving that binary outdated while potentially modifying an unrelated installation. Keep this fallback manual for Codex unless the executable proves a standalone install or its matching home can be derived.

Keep oversized mise wrappers manual-only.

For an oversized mise launcher at an otherwise unowned Pi command path, isMiseWrapperScript returns false. The resolver can then expose Pi’s update --self action using the resolved wrapper path, contrary to the manual-only rule for mise installs. Keep wrapper inspection failures from turning a mise-managed install into a native-update fallback.

Update `isMiseWrapperScript` so an oversized launcher or failed file inspection
cannot be treated as a native Pi install; preserve the manual-only outcome for
mise-managed installs when the wrapper cannot be inspected.

## Provider updates run only through the owning installer

A one-click update is offered only when the resolved executable's path proves which installer owns
it. Homebrew and npm are proven by the real path (symlinks followed): a versioned keg or cask under
A package manager runs only when the resolved executable's path proves it owns the install. Homebrew
and npm are proven by the real path (symlinks followed): a versioned keg or cask under
`brew --prefix`, or `<prefix>/lib/node_modules/<pkg>/` (Windows: the shim beside `node_modules`).
Native installer layouts and the global bin directories of pnpm, Bun, and Vite+ may match on either
the resolved path or its real target, since those installers place real files or their own symlinks
there. Cursor and Grok are the exception: their only updater is the CLI itself, which detects its
own installer, so any resolved executable runs `<binary> update`. Anything unproven stays
manual-only but still reports the version gap. npm updates pin
`--prefix` because the `npm` on `PATH` can belong to a different Node than the one that owns the
provider. Homebrew
Native installer layouts and the global directories of pnpm, Bun, Yarn, and Vite+ may match on
either the resolved path or its real target, since those installers place real files or their own
symlinks there. Volta is proven by its `volta-shim` link plus the package's image directory. When
nothing is proven, the provider's own updater (`claude update`, `codex update`, `opencode upgrade`,
`pi update --self`, `grok update`) runs instead, because each one detects its installer itself;
the runner's version check catches an updater that exits 0 without updating. Mise installs stay
manual-only because their version is pinned in mise's config. npm updates pin `--prefix` because the
`npm` on `PATH` can belong to a different Node than the one that owns the provider. Homebrew
compares against `brew info` since casks trail npm by hours; native installs share npm's version
train, so the registry stays authoritative for them.
