Maven can now be told who someone is. She cannot yet tell who is speaking, and this commit is careful to say so rather than pretend otherwise. What works: profiles are enrolled from several deliberately recorded samples, listed, and deleted. They live in the existing memory_vectors table under a "speaker:" id prefix, so there is no migration; what that needed was a wider interface than memory.Store, hence memory.Catalog with ByPrefix and Delete. Delete is the load-bearing half — a voiceprint someone asked to be rid of has to actually go, and a search-only store cannot do that. InMemoryStore.Insert became an upsert by id to match what the persistent store already did. What does not work, and why it is not faked: there is no speaker-embedding model on this box. Sixteen ggufs in /mnt/hdd1/llms, all text; no ECAPA, no x-vector, no titanet, no wespeaker, no .onnx anywhere under /mnt/hdd1. So newSpeakerEmbedder returns nil, internal/speaker falls back to speaker.Disabled, Identify answers ErrDisabled, and the daemon logs which half is off at startup. The plan's "simple MFCC + GMM" floor is refused in the package comment: MFCC cosine distance detects channel and loudness as much as voice, and a biometric that is confidently wrong writes false claims about named people into his memory. A bad floor is worse than none here. Refused as well, and the reason is in enroll.go's doc comment: the plan asked for unknown speakers to be enrolled on first interaction with a TTS "кто это?". There is no request shape in the protocol that could express that. Taking a biometric of whoever walks past the microphone does it to guests who are not party to the exchange, and a synthesised question into a room is not consent from whoever answers. Authority: enrolment is AuthStepUp, because it is a deliberate sit-down act that writes a biometric of a named person and never something done by voice mid-conversation. Deletion is one rung lower at AuthWrite, deliberately inverting the usual pattern — getting rid of a biometric must never be the harder half. Listing is AuthRead and never returns the vectors themselves. Off unless configured: no speaker block means the three methods answer ErrUnknownMethod, so a default box has no wire path that takes a voiceprint. make build and make test pass.
