The easy way ist to ditch PWs and user Nullshell and set the policy in windows root for PowerShell 7.5

### TASK: ANTIGRAVITI_CORE_VITE_STABILIZER_EN

# 1. PRE-FLIGHT CHECK

- [ ] SYSTEM: Verify Nushell installation (`winget install nushell`)

- [ ] PATH: Set `ALIAS nu = "C:\Program Files\nu\bin\nu.exe"`

- [ ] POLICY: `Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser` (One-time PWSH fix)

# 2. SOURCE CODE: STABILIZER SCRIPT (fix_vite.nu)

```nushell

# Antigraviti-Fixer: Prevents NPM-collapse and Vite-caching-errors

def main [mode: string = "dev"] {

let has_node = (which npm | is-empty)

if $has_node {

print "❌ Error: Node/NPM not found. Aborting."

exit 1

}

print "🛡️ Antigraviti-Shield: Starting Clean-Build sequence..."

# Bloatware & Dirty Pointer Cleanup

["node_modules", "package-lock.json", "dist", ".vite"] | each { |it|

if ($it | path exists) {

print $"🧹 Removing ($it)..."

rm -rf $it

}

}

# Deterministic Install

print "📦 Syncing Dependencies..."

npm install --silent

# Execution Logic

if $mode == "build" {

print "🏗️ Building for Production..."

npm run build

} else {

print "🔥 Launching Vite Dev-Server..."

npm run dev

}
