Executable files lose their mode bit.

Member previewVariant 3 · 3 implementations · 4 checks per implementation

Case contract

Return sorted entries with normalized owner/group, fixed timestamp, preserved executable distinction, and file payload. Ignore input owner, group, and timestamp.

Why this case matters

An offline model of reproducible archive metadata, suitable for testing build and release tooling without external services.

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
fixture 2	`[["a", 0, 0, 100, 420, "a"], ["b", 0, 0, 100, 420, "b"]]`	`[["a", 0, 0, 100, 420, "a"], ["b", 0, 0, 100, 493, "b"]]`	Failed
