OpenAI Codex, working in SaveTheRbtz/zstd-seekable-format-go, fixed a thread-safety gap: reads through the readSeeker path take a mutex when the underlying reader lacks io.ReaderAt. It also adds a concurrent ReadAt test. The change touched two files across two commits, adding 60 lines and removing eleven. It merged clean after 4.19 hours, with no changes requested.
