# Chantier 3 — GDN prefill sur HTP
Constat: skel gated-delta-net-ops.c:98 boucle deja sur n_tokens (recurrence complete). Gate 2284 = conservateur. Leve via GGML_HEXAGON_GDN_PREFILL=1. Mesure: pp512 50.1->55.5 (+11%) kernel scalaire, gratuit. Decode inchange. Validation qualite court OK. Reste: chunkwise HVX parallele = sujet semaines (aide partielle scan bit-exact) pour viser >100. ETAPE 1 acquise.
Skel gated-delta-net-ops.c:98 boucle sur n_tokens. Gate 2284 leve (test) -> pp512 50->55 MAIS sortie CHARABIA ("He thef% sur"). Kernel scalaire pas bit-correct au prefill (handoff etat S faux multi-token). +11% INVALIDE. Defaut remis CPU (GGML_HEXAGON_GDN_PREFILL=1 = opt-in test only). Vrai B-2 = corriger recurrence/etat + HVX chunkwise, bit-exact = semaines, aide partielle. Etape acquise: gate localise, kernel a fixer identifie. Pas de gain livrable.
