The duplicate ports neural/jpegai_hyper.rs and neural/jpegai_mans.rs, which the float
decode path ran its front half with, are deleted (O10): that path runs the shared
driver since the switch. The direct pieces of the exact decoder leave production,
test-only (legacy_int): the crate-root mANS port (jpegai_mans), the hyper-scale network
(jpegai_synthesis::decode_hyper_scale and its convolution) and the pipeline's
skip_mask, rvs_additive, rvs_likely and sigma_index. The calibration tests that read
them require legacy_int.
jpegai_mans_golden runs on E8 and the scale graph alone; jpegai_e2e (the float chain
against the reference PNG) takes its front half from the driver, still checking the
dumped RVS additions, masks and residuals; the byte-equality crate drops the neural
port and keeps E8 and the direct port.
