Fix A: generate_audio() now raises a clear RuntimeError instead of AttributeError when speech_outputs is None/empty (corrupt or over-quantized weights emit no speech tokens). Fix B: warn_if_lowbit_quantization() detects naive int casts (raw I8 tensors with no scale metadata) in safetensors and sub-4-bit I-quants in GGUF at load time. Root-caused via diagnostics: iq3_xxs garbled output = over-quantization (relerr~0.22/cosine~0.978 vs original, controls cosine=1.0); int8 crash = naive cast + unguarded None. 15 new tests; full regression 725p/5f/4s (5f pre-existing).
