## Title

    Reproduction request: Codex turn-diff checkpoint refs under refs/codex/turn-diffs/checkpoints/ may retain full project tree snapshots as git l

## Body

    What I found:
    Codex turn-diff checkpoints are stored as git refs under refs/codex/turn-diffs/checkpoints/ pointing at tree snapshot objects.
    Reporter on Codex Desktop 26.616.51431 measured about 102 GiB in 8476 loose git objects with checkpoint refs present and git count-objects -vH showing size about 101.86 GiB while size-pack was about 4.64 MiB.
    
    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 a shipped Codex release adds checkpoint garbage collection, .gitignore-aware snapshotting, or size limits.
    
    Useful next check:
    Whether a shipped Codex release adds checkpoint garbage collection, .gitignore-aware snapshotting, or size limits.
