The first `_` is arguably acceptable since `t.TempDir()` is valid, but the pattern is inconsistent with `TestDiskCacheMissThenHit` which checks the error. Low risk here, but worth standardizing.\n  - **Minor:** No explicit file permission set on the temp file. `os.CreateTemp` uses `0o600` by default on Unix, which is fine and actually more secure than `0o644`. Not a bug, just worth a comment if the intent is \"only owner can read cached tarballs.\"\n  - **Minor:** `path()` and `Get()` have no doc comments; only `NewDiskCache` and the struct itself do. Not a blocking issue given the methods are unexported (`path`) or self-evident, but `Get` is exported.\n\n**Assessment: APPROVED**\n\nThe implementation is correct, atomic, and leak-free.
