 HTP pp512=45/pp1024=45 plat: partie batchable saturee des pp128 (ne prouve PAS la taille du GDN). CPU 18.7=53.5ms/tok modele entier (PAS GDN isole). HTP 22.2ms = GDN_cpu+R_htp, donc GDN_cpu<22.2 borne haute. Recompense B-2 entre ~62 et ~160 t/s selon GDN_cpu non mesure. Profiler HTP (GGML_HEXAGON_PROFILE+OPSYNC) inerte: cli pend AU prefill, bench masque DEBUG. Mesurer GDN_cpu = prerequis avant engager kernel; debloquer cli ouvre le profiler. Existence B chiffree, recompense NON.
