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

What I found: In public codex-rs git-utils baseline.rs, write_tree recursively walks directories and write_blob stores full file bytes for each file, skipping only a .git directory entry—not project .gitignore rules. Issue #29388 states Codex does not trigger git gc or git prune after superseded checkpoints, so unreachable loose objects can accumulate while default gc.pruneExpire is two weeks. 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Still unknown: Whether OpenAI will ship automatic pruning of superseded turn-diff checkpoint refs and their unreachable objects. Useful next check: Whether OpenAI will ship automatic pruning of superseded turn-diff checkpoint refs and their unreachable objects.
