Module load cost
Counted with a module.registerHooks load hook, compile cache disabled. Counts every JS module actually evaluated on that code path (built-ins excluded, native addons excluded).

Install footprint and published tarball
Each version installed on its own into an empty project with nothing but @nuxt/cli as a dependency, so the tree is exactly the CLI and its transitive dependencies. npm cache is warm and the registry is only consulted for metadata, so install wall time is indicative, not a network benchmark.
| Metric | baseline v4.0.0-alpha.0 | head v4.0.0-alpha.0 | Delta |
|---|---|---|---|
Direct dependencies of @nuxt/cli |
21 | 21 | 0.0% |

| Published tarball (unpacked) | 984.6 kB | 987.3 kB | +0.3% |
| Files in tarball | 131 | 131 | 0.0% |
Interleaved runs on a shared runner: trust the deltas, not the absolute timings. The dev, restart and build suites run locally via pnpm bench:cli.

In `@packages/nuxt-cli/src/commands/index.ts`:
- Around line 29-34: Update the subCommands construction to preserve
resolver-valued subCommands: resolve the parent subCommands function before
enumerating its entries, then wrap each resolved command with withRemedy while
retaining the existing direct-object behavior. Add coverage for subCommands
configured as a resolver returning an add command.
In `@packages/nuxt-cli/src/dev/tui/index.ts`:
- Line 576: Update the restart flow so its finally handling does not set status
to ready when context.restart() rejects; preserve loadFailed and the existing
error state on failure, and mark the panel ready only after a successful
restart. Add a regression test covering a load error followed by a rejected
restart and a subsequent page error.
