Root cause found: QNN HTP level=1 compilation is not bitwise deterministic. Two loads of the same .pte produce slightly different hidden states → audible trembling in decoded speech. Java pipeline uses single QNN instance → no trembling, validated quality. C++ pipeline code preserved for future use when QNN context caching is fixed (would make both loads use same compiled graph).
