# TP4 production image (.env.tp4.example, docs/tp4.md). Same pinned base image as Dockerfile, but
# the SGLang python tree replaced by the upstream dsv4.1 branch at f80c91a4b (2026-09-16 19:45 UTC;
# carries #39370 mHC/metadata fusion, #39653 communication kernels, #39648 top-k, #39646 kernels)
# with the kernel packages the branch pins (sglang-kernel 0.4.7, sgl-deep-gemm 0.2.0; aarch64
# wheels from PyPI), rhys101's SG17 RoCEnante overlay adapted to TP4, the SG17 b12x (RoCEnante)
# plus sparkring's roce_ring, b12x main as b12x_next (routed MoE at EP_SIZE=1), and all adapters.
# The SM120 page-split override (runtime/flash_mla_sm120.py) is re-applied on top of the branch's
# kernel file. Third-party trees are fetched at build, at the commits and sha256 in
# runtime/sources.manifest (scripts/fetch_runtime.sh), and patched with the files in this repo.
