+
+Approval nodes: `minApprovals` now documents its real per-behavior default.
+
+The property described itself as "Default 1", but an omitted threshold has never
+meant 1 under `behavior: 'quorum'` — the approval runtime falls back to the
+resolvable approver count, so a quorum node authored without `minApprovals`
+requires **every** approver rather than one. Under `behavior: 'per_group'` the
+fallback really is one approval per group.
+
+The schema text and the generated reference table now state both defaults. This
+is a documentation correction only: no schema default was added, the accepted
+value set is unchanged, and no stored approval flow changes behavior.
