# Authoritative build inputs — GLM-5.3-Flash r12 (jovian-judgement) clean build.
# Every entry is a tag or exact version — no :latest, no main, no ranges.
# Pattern: solar-open2-nvfp4 (raw CUDA base, staged wheel builds, ccache/uv
# buildx caches) — content r12-specific per the rtx6kpro source contract.

# r18 composition (2026-09-05): branch tip f564dffe9a66 — supersedes the r17
# base 9c4dd054 (which itself superseded r12's 54f6e9826c + PR set 550-557;
# do NOT re-merge 550-557, they conflict). The r17 PR set 579/580/581/586 is
# now merged into the tip; only 582 is still open, pinned by head SHA.
# New in this window (9c4dd054..f564dffe + b12x below): RoCEnante one-shot
# RoCE collectives (PR #597; env VLLM_ENABLE_ROCE_ALLREDUCE, off by default),
# B12X NVFP4 KV cache (fp8_ds_mla / nvfp4_ds_mla), DFlash split-KV paged
# decode attention, L2 weight-prefetch decode, DSpark input-budget split,
# spec-decode KV-connector + prefix-cache-block fixes, GLM tool-delimiter
# parser hardening, prefill fairness engines, KDA prefill backend,
# FlashKDA stable-inverse fix. No requirements/setup.py drift vs r17.
