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

What I found: Codex creates refs/codex/turn-diffs/checkpoints/ refs that store full project tree snapshots as git objects, and large binary files can inflate loose object storage. A follow-up comment on the same issue recommends confirming loose size with git count-objects -v, checking unreachable objects with git fsck --unreachable, reviewing git stash list before pruning, then using git gc --prune with an explicit age.

Useful next check: Whether Codex Desktop or CLI versions after 0.159.2 still write full-file blobs for every checkpoint on large-binary projects.
