# BLOCKED 2026-09-08 (r28 re-test): the r28 tree advanced the DCP+DFlash
# boundary logic (fa4720ea) but the drafter still dies — now at
# backend selection, not the old C4 assert: the DFlash attention kernel
# is BF16-KV-only ("K and V caches must be bfloat16") while the GLM-5.3
# engine runs fp8_ds_mla KV (fork default; no per-drafter dtype override
# in this tree) -> "No valid attention backend found ... kv_cache_dtype=
# fp8_ds_mla, use_mla=False, block_size=256". Fork-side work: teach
# DFlashAttention the fp8_ds_mla KV, or add a drafter bf16-KV override.
#
# DFlash2 re-test on the r28 full stack (2026-09-08, operator: "maybe it
# works now"). The 2026-09-06 blocker (C4 parent-page stride assert + FP8-KV
# drafter backend rejection) targeted the r27 tree; r28's vLLM carries
# fa4720ea "fix(cache): restore GLM boundaries across DCP and DFlash groups"
# + the #646 2048/256 page split, so the geometry may now line up.
