Rather than saying that the relative path adds additional +entropy, what I was aiming at is the file-system cannot have two +alternate versions of one file name at the same path with the same +mtime, and that’s why it occurred to me that encoding both path and +mtime within the key doesn’t just increase the odds, but effectively +_guarantees_ that there won’t be any collisions.
