Invalid value for --${name}: ${raw}

Error message

Invalid value for --${name}: ${raw}

What it means

parseNumberFlag() in pre-wrap-check.ts is the same shared helper as in the other oracle scripts: it parses a `--<name>=<value>` integer flag and throws when Number.parseInt is non-finite. It guards the port/timeout flags for the pre-wrap oracle runner.

Solutions

1. Supply an integer, e.g. `--port=3210` / `--timeout=60000`.
2. Omit the flag to use the fallback default.
3. Confirm the flag name in the message is one consumed by pre-wrap-check.ts (port/timeout).

Example fix

# before
bun run pre-wrap-check -- --port=any

# after
bun run pre-wrap-check -- --port=3210

function readNumberFlag(name: string, fallback: number): number {
  const prefix = `--${name}=`
  const arg = process.argv.find(v => v.startsWith(prefix))
  if (arg === undefined) return fallback
  const raw = arg.slice(prefix.length)
  const n = Number.parseInt(raw, 10)
  if (!Number.isFinite(n)) {
    console.error(`--${name} expects an integer, got: ${JSON.stringify(raw)}`)
    process.exit(2)
  }
  return n
}

const isIntegerString = (v: string): boolean => /^-?\d+$/.test(v.trim())

When it happens

Trigger: Running `bun run pre-wrap-check -- --port=abc`, `--timeout=` (empty), or any value whose base-10 parseInt is NaN.

Common situations: Typo in a wrapper script, unexpanded shell variable, or a stale placeholder value.
