-- The bounded opportunity family supports one open need from exact known
-  evidence: `restock_empty_pantry`, `supply_missing_wood`,
-  `feed_weak_villager`, and `repair_home_roof`. The pantry and weak-villager
-  needs resolve through real food supply (the weak need only when the

-  selection after urgent self-care and schedule precedence. There is still no
-  helper assignment, acceptance, rewards, free-form dialogue, or quest log.
+- The legacy bounded opportunity family supports one open need from exact
+  known evidence: `restock_empty_pantry`, `supply_missing_wood`,
