readGitCheckout loaded node:child_process through require(), which does not exist in the ESM API runtime. Linking a project space to a folder that is a git checkout therefore failed after the space was created. The lazy load is no longer needed: the reader is only reachable through the server-only "@rakazo/core/git-checkout" subpath, never through the package entry the web app bundles. Import spawn at the top instead. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MRtGG9ARfqqhma3t85Ro2u
