Verified in the shipped image (v1/worker/gpu/cudagraph_mem.py):
estimate_cudagraph_memory() checks VLLM_CUDAGRAPH_MEM_ESTIMATE_MB FIRST and
returns that MiB total outright, ignoring the BASE/PER_GRAPH pair — the only
way to state the CUDA-graph plan term directly instead of deriving it. We
keep shipping the pair (0/12) so a future spec-decode shape re-prices
automatically; documented the switch condition.
Also corrected two stale shape-G claims in the runbook that predated the
1.00 revert: the deployed shape block and the lever table both still said
util 1.0 / 'le=1 ceiling', while shape G ships 0.982.
