Discover lists speech models with the voices each accepts and a + Add that puts the model on tts.roster. The Roster card lists every model with a voice picker, Test, Make default and Remove. Test on any row (or a discovered model not yet added) fills the test panel's voice list with that model's voices, so Orpheus and Kokoro can be heard one voice at a time before either is chosen. The default is a pair — PUT /config/tts/default sets tts.model and tts.voice together and refuses a voice the model does not accept, naming the ones it does. The generic setter no longer takes tts.model/tts.voice one at a time, which is how a Kokoro voice got paired with Orpheus. A default that leaves the roster stops being the default. Users pick from the voices of every roster model, grouped by model in Settings; the stored value is "model|voice" so read-aloud sends the voice to the model that accepts it. A bare voice saved before there was a roster is read as a voice of the default model. chooseTTS is the one place the pair is decided, shared by read-aloud, the admin test and the settings options.
