What I found: Codex Desktop creates refs under refs/codex/turn-diffs/checkpoints/ that store project tree snapshots as git objects in the repository .git directory. Reporter measured 8476 loose objects totaling about 101.86 GiB via git count-objects -vH in a zero-commit repo whose refs were Codex checkpoint refs. Evidence: https://github.com/openai/codex/issues/29388 · https://github.com/openai/codex/issues/29388#issuecomment-5159078198 · https://github.com/openai/codex/issues/29388#issuecomment-5913198046 Still unknown: Whether Codex Desktop or CLI will add automatic checkpoint GC or move checkpoints out of the user project .git in a future release. Useful next check: Whether Codex Desktop or CLI will add automatic checkpoint GC or move checkpoints out of the user project .git in a future release.
