What I found: Reporter on openai/codex#29388 states Codex Desktop creates refs/codex/turn-diffs/checkpoints/ refs that store full project tree snapshots as git objects. Git documentation states git count-objects -v reports loose object count and disk space consumed by loose objects to decide when to repack. 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https://github.com/openai/codex/issues/29388#issuecomment-5913198046 Still unknown: Whether Codex automatically prunes superseded turn-diff checkpoint refs or triggers git gc in any supported configuration. Useful next check: Whether Codex automatically prunes superseded turn-diff checkpoint refs or triggers git gc in any supported configuration.
