Delete the miscalibrated sm_120 SAME-S fp8 encoder
Verified signatureIts activation quantisers were calibrated with a percentile-of-percentile plus a 1e-4 floor, putting the clip points far below where the decoder's plain amax puts them. The equivalent sm_90 engine was deleted when that was found; this copy was missed and only surfaced when the deprecated engines were swept into legacy/. Keeping it under legacy/ would have left a trap: it is the one file there that is wrong rather than merely superseded, and anyone building sm_120 from it would inherit the bug. The recalibrated weights live in onnx/same-s/enc_fp8.onnx, which build_autoencoders.py uses to produce enc_fp8_chunkable.trt.197c684 -
Move deprecated sm_120 TRT engines under legacy/
Verified signatureThese are not reachable from the runtime registry: every tier resolves to the chunkable engines (dec_*_chunkable_limiter / enc_*_chunkable). Kept rather than deleted so older checkouts and reproductions still have them, but moved out of the way so the live set is unambiguous. Copies are server-side; the ONNX sources are untouched, and four of them (enc_dynamic_triton_swa.onnx, enc_dynamic_bf16.onnx, both enc_fp8.onnx) remain load-bearing for build_autoencoders.py -- 'chunkable' is a profile choice for the encoders, not a graph change.19ab22a
