entry_source took a name or path hit before reading the hashes the entry
declares, so the gap report and the site counted as held a file whose
only homonym has other bytes: zquestclassic's ending.mid and gameover.mid
matched Hydra Castle Labyrinth's. A name or path hit now counts only
when its record carries one of the declared hashes, and the declared
content anywhere in bios/ comes before a data/ copy. Measured over every
profile entry: 254 change, 248 bundled ones (report and site only),
three unsourceable SC-55 revisions now read missing, three data hits
read bios by hash.
