 ## Cmp 4B vs 9B: signal partiel
 9B analyse + riche, 4B quasi-vide. Les 2 comprennent FR. Mais cli=decode HTP 0.6t/s + reasoning anglais, /no_think ignore -> eval FR propre IMPOSSIBLE en shell. Reco 9B qualite, 4B RAM. Vrai cmp = JNI (decode CPU+template). Prouve sur 4 runs.

+BUG=enable_thinking default true -> /no_think ignore -> ramble anglais. FIX: --reasoning-budget 0 (arg.cpp:3061). Prouve: 4B->FR bref coherent "Je suis desole que tu te sens ainsi". Batch shell A/B reste impossible (HTP decode 0.6, EOS variable). Vrai cmp 4B vs 9B = JNI: decode CPU+template+budget0. Engine OK, cascade tient RAM.
