The base-node-deps Docker build failed because .npmrc routes @esbuild-kit
packages to localhost:4873 (Verdaccio), which is unreachable inside BuildKit.
- Add Verdaccio service to docker-compose.stack.yml with patched tarballs
- Start Verdaccio in Gate 7 Tier 1 before base-node-deps build
- Configure buildx with network=host so BuildKit can reach localhost:4873
- Update verdaccio.yaml storage path for container volume mount
