Package manager
npm with the committed package-lock.json (npm ci). The repository does not declare a packageManager field for pnpm or yarn: the lockfile and CI are npm-based, and a second lockfile would create version drift.
Network compatibility
A network entry means a deployment path is configured, not that the system was validated there. Before deploying: confirm EVM version support (paris is intentionally conservative), gas limits, finality assumptions, explorer verification and upgrade governance (see SYSTEM-DESIGN.md §8).
