Ultima onda CLI. 4 cmd portati con rename + grep-per-file (3 residui nsp nei messaggi fixati). Nessun drift costanti phase in questi cmd. La CLI tht e' ora COMPLETA: 14 gruppi di comandi (phase config schema session vector memory search evidence db decision sql cte datamart lsh). tht --help li list tutti. Suite: 165 passed. Il loop skill->LLM->gate ora ha tutti i comandi che la skill chiamera'. Resta: skill riscritta (S), setup pre-sessione (0b), sessione L2 manuale.
