Reproduction request: Codex Desktop refs under refs/codex/turn-diffs/checkpoints/ retain project tree snapshot git objects; loose object store

What I found: Reporter on openai/codex#29388 found only refs/codex/turn-diffs/checkpoints/ refs while thousands of loose git objects accumulated (~101.86 GiB loose) in a zero-commit repo used with Codex Desktop 26.616.51431. Issue #29388 documents reporter workaround git gc --prune=now (or re-init .git) reducing total project footprint from about 140 GB to about 5.7 GB after cleanup.

Useful next check: Whether Codex Desktop versions after 26.616.51431 still write full-file blobs on every checkpoint without pruning superseded refs.
