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

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.
