b300-equivalent matrix: E7b high-concurrency retest (MRR64 + decode-graph buckets 1-64) - graph-drop cliff fixed, report numbers overwritten in place
- deploy_glm53_e7b_hicc.sh (md5 165db732): only delta vs 607_exp = MRR 16->64 + cuda-graph-bs-decode 1..64; KV pool 276,480 unchanged, avail 6.11GB after capture
- 10 retest points (16K/4.1/4.2 at c8/16/32/64) all OK, hit=0.0 (fresh container = recycled windows virgin again), 0 retraction, QG 7/7
- verdicts: 16K output 92.1/97.6/99.6 (+18~33% vs initial, still TP2PP4-dominated, prefill wall ~100 plateau); 4.1 c32/64 229/272 (gap narrowed to 1.2x); 4.2 402/676/826.5 - E7b wins ALL cc tiers, c64 826.5 tok/s = machine-wide best output (+72% vs TP2PP4 482), TTFT 12.18s / TPOT 85.1ms; c8 anchors within +-3% prove no env drift
- REPORT.md + Feishu A7V3wZTQeifCB4krdi6cA834nW9 overwritten in place (user directive: no appended chapter); initial MRR16 run archived as baseline in results/e7b/
- provenance.md: e7b64 VRAM (idle 79.3k, peak 83,627 MiB), second in-service restore verified (fired up/health 200/16K+C4 spot/KV pool 647,040 identical)
