The CTC model (onnx-community/parakeet-ctc-0.6b-ONNX) only has an encoder — no decoder_joint or nemo128 preprocessor. transcribe-rs expects a TDT transducer variant with all three. Switch to istupakov/parakeet-tdt-0.6b-v2-onnx which has the correct int8 files. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
