Quantify the two multi-tenant wins that are properties of the host-side
block model (vLLM-parity), independent of the in-model compute path:
WIN 1 concurrency capacity @ 512-block budget
contiguous (reserve n_ctx/seq): 4 sequences
paged (on-demand blocks): 37 sequences
--> 9.2x more concurrent sequences
WIN 3 cross-tenant prefix sharing (32 tenants, 1024-tok shared prefix)
prefix-cache OFF: 2176 physical blocks
prefix-cache ON: 192 physical blocks
--> 11.3x less KV memory
WIN 2 (throughput) is deliberately reported as PENDING: it requires the
paged gather-read path wired into llama-graph.cpp (Gate 0) and is not
measurable at the allocation layer. The win-1 baseline is per-sequence
n_ctx reservation (stream mode); llama.cpp's unified cache already shares
one pool, so the honest win there is on-demand sizing + prefix dedup.
Phase 3 (partial) of docs/superpowers/plans/2026-06-19-paged-attention-llamacpp.md.
