Reproduction request: Codex turn-diff checkpoint refs may keep project snapshot git objects without garbage collection; a reporter says cleanu

What I found: Reporter on Codex Desktop 26.616.51431 measured git count-objects -vH with count 8476 and size 101.86 GiB loose objects in a zero-commit repo whose only refs were Codex checkpoint refs. A 2026-09-30 follow-up comment on openai/codex#29388 states the checkpoint disk growth issue was still not addressed and still happens in codex-cli 0.159.2. Evidence: https://github.com/openai/codex/issues/29388 · https://github.com/openai/codex/issues/29388#issuecomment-5913198046 Still unknown: Whether checkpoint snapshot blobs are recreated at the same rate after any manual object-store cleanup. Useful next check: Whether checkpoint snapshot blobs are recreated at the same rate after any manual object-store cleanup.
