// Orchestration ggml-side du Talker engine.
|
|
//
|
|
// Boucle decode : engine Talker fait son vrai forward + greedy sur CB0 ;
|
|
// CB1..15 teacher-forcés depuis codes_golden_NxCB.bin (CP non intégré encore).
|
|
// next_embed = Σ talker.tok_embd[CB0] + Σ cp_codec_embs[i-1, CB(i)] + tts_pad_embed.
|
|
// (En x_vector_only_mode, trailing_text_hidden == tts_pad_embed exactement, vérifié.)
|
|
//
|
|
// Sortie : codes_engine.bin [N, 16] int32 = ce que l'engine produit. À décoder
|
|
// ensuite avec qwen3tts-decoder-test pour obtenir un WAV.
|
|
//
|
|
// Validation parallèle : à chaque step, on compare next_embed engine-side vs
|
|
// talker_step_inputs[s] Python (qui a la même formule). RMSE ~0 attendu (lookups
|
|
// dans les mêmes tables, mêmes codes forcés, même sommation).
|
|
//
|
|
// Usage : tts_orchestrate <gguf> <dump_dir> <out_codes.bin> [cpu|htp] [max_steps]
