The edge gave an unnamed release a "lone" probe target only when it had exactly one file, so a release of several random-named pieces (Bob's, 1.55M rows in five groups) reached the pending store with no target at all: never claimed, never named by a twin, its class never learned. candidates_of now takes the first random-named file when there is no par2, archive or 7z volume. The batch store writes a finished release without a target as exhausted instead of waiting, and leaves it out of its class's waiting count. LOG.md (140).
