   Diagnosis

   .repos/alchemy-effect/.vendor/alchemy is a mode 160000 gitlink (c9f5e549cf023632c3df948c207a58336192b3c7) and this repo has no root .gitmodules. git submodule status exits 128 with no submodule mapping found in .gitmodules for path '.repos/alchemy-effect/.vendor/alchemy'. It is the only gitlink in the index.

   The pointer arrived with the alchemy-effect subtree in bd851c020 (chore: add Alchemy reference repo subtree). Upstream .repos/alchemy-effect/.gitmodules declares that path as a submodule of https://github.com/alchemy-run/alchemy.git with update = none, and comments that it is a ~900MB reference-only checkout skipped even by alchemy-effect CI. git subtree copies the gitlink and does not promote the nested .gitmodules entry, so the parent repo has a submodule pointer and no mapping.

   Lean GitHub-hosted CI still succeeds: actions/checkout clones into an empty workspace, and .github/workflows/ci.yml deliberately avoids persist-credentials: false because that path runs git submodule foreach and dies on this gitlink. A self-hosted checkout that cleans a persistent worktree runs the same git submodule foreach during clean, fails, and has to recreate the repository.

   Scope

   Remove the unmapped gitlink with git rm --cached. Do not materialize the ~900MB checkout, and do not add a root .gitmodules mapping — .repos/ is vendored as a subtree, not a submodule. Drop the CI comment that only exists to dodge this pointer, and strip unmapped gitlinks after sync:repos so the next alchemy-effect subtree pull does not put it back.
