The current Paper 45 benchmark does not claim that literal daughter universes have already been directly simulated or that resolved black-hole interiors are fully understood in QGEFT. It does show that the multiverse search now cleanly separates viable universes from fertile ones. In the current `5`-generation benchmark, the best universe reaches fitness `3.4181` and terminal maximum degree `16`, still far below the reproduction threshold `40`, leaving a fertility gap of `24`. The defensible conclusion is therefore that black holes are best interpreted not as cosmological garbage bins but as the missing reproductive valve of the multiverse: without sufficiently strong local hub-collapse, universes remain sterile.
