F1–F3 + F2-broad + gaps B/C/D shipped; ADR-0036 opened, /runda'd, reframed to the surgical "validate-and-retain, verbatim" principle, and Phase 1 (advanced-mode INSERT literal validation + offending-value retention) implemented. Phases 2–3, X4 (serial auto-fill bug), X5 (framework cohesion), and the natural-order error-value display remain. 1930 pass / 0 fail / 0 skip.
