The outputPath variable is computed but never used. The assertion checks for 'out' directory existence, but this appears unrelated to the stripping operation. Either remove this unused code or clarify its purpose if it's meant to validate something about the strip operation.

Suggested change

	const outputPath = path.join(buildPath, "out");
	assert(
	fs.existsSync(outputPath),
	`Expected output file in ${outputPath}`,
	);

[Copilot]

The error message says 'Expected output file' but the check is for a directory named 'out'. The message should say 'Expected output directory' to accurately reflect what's being validated.

Suggested change

	`Expected output file in ${outputPath}`,
	`Expected output directory at ${outputPath}`,
