Implement KeySource::resolve_unit_keys for KeydbSource by splitting unit_keys_from into resolve_from, which reports: whether find_disc matched; the specific miss reason (NoVid when a Media Key has no VID, else NoDerivableKey); the matched entry's shape (vuk / unit_keys count / media_key / keydb_vid / enc_title_keys len / vid_available); and the loaded entry count for a self-diagnosing true-miss verdict. MultiSource forwards resolve_unit_keys so a matched inner source's richer verdict survives composition. No derivation-logic change: the locked VID-per-path rule is intentional and the investigation found no correctness bug there — only the conflated verdict. Tests cover matched-no-VID, matched-no-material, true miss, and the success path.
freemkv-keysources
Pluggable AACS key sources (keydb, online key service) for
libfreemkv. Each source looks a disc up
and hands libfreemkv its terminal Unit Keys via get_unit_keys; the library
does all derivation.
