# GLM-5.3-Flash r12 (jovian-judgement) — CLEAN build for DGX Spark (aarch64/sm_121a)
#
# Per operator direction: start from a raw CUDA image (solar-open2-nvfp4
# pattern), NOT the day-0 vllm image. No baked-vllm contamination: torch,
# flashinfer, vLLM and b12x all come from pinned sources in this file.
#
# Stack (rtx6kpro models/glm-5.3-flash.md source contract):
#   vLLM  = local-inference-lab/vllm @ 54f6e9826c (dev/jovian-judgement base)
#           + sequential merges of PR heads 550,552,553,554,555,557
#           (the doc's "composition commit" 7d8a09c… is not a public ref)
#   b12x  = local-inference-lab/b12x @ 139e04048b (master) + PR heads
#           260,267,268,269,270. b12x is pure-Python: the kernels are
#           CuTe-DSL / tvm-ffi JIT (nvidia-cutlass-dsl 4.6.2), no CUDA
#           compile at install time.
#   torch = 2.13.0 cu130 (the fork's requirements/cuda.txt pin)
#   flashinfer = 0.6.17 (day-0-era; not a pip dep of the fork since 0.6.14,
#           so installed from the flashinfer.ai wheel index)
#
# GB10 sm_121 fix baked in (patch_cuda_sm12x.py): the sm12x auto-priority
# list in vllm/platforms/cuda.py offers only TRITON_MLA (no sparse) and
# FLASHINFER_MLA_SPARSE_SM120 (head 576 only) — neither fits GLM head-512.
# B12X (supports (12,0)/(12,1)) is inserted first.
#
# Build: cd docker-images/glm53-jovian-r12 && bash build.sh   (on a Spark node)
