Tool synthesis from failure

Build (Module 12, L12.3), interview checkpoint. A 20-run log has 16 raw failure strings that normalise to datetime x12 and network x4. Threshold 5 keeps one cluster; threshold 2 keeps two; threshold 20 keeps none. Network stays excluded at threshold 4. Day-first is forced by one slash date. The held-out arena moves 1/10 to 10/10 with overlap 0. In-memory only; no model.
