 What it means: the box is deterministic for a given commit and path, so a release built on it can be checked by anyone with the
 same toolchain by rebuilding and comparing; the shipped 0.3.14 and 0.3.15 Linux bytes came from the Mac's zig lane with a
 build clock inside and cannot be reproduced anywhere, and the Windows 0.3.14 exes carried a PE timestamp. The reason to ship
