+The first bounded Milestone 7 opportunity proof is complete:
+
+- a positive NPC food withdrawal from `village_pantry`, combined with the
+  pantry currently being empty, is the exact shortage evidence;
+- the need opens only when a living critically hungry villager knows that
+  event through performance, witnessing, or the existing one-hop
+  communication contract;
+- highest hunger and then lowest stable NPC ID select one interested villager,
+  with at most one open pantry need;
+- schema-v8 opportunity records retain stable NPC, event, storage, resource,
+  and resolution IDs, and protect the trigger memory while the need is open;
+- an exact later NPC food deposit or player resource extraction into the
+  pantry resolves the same record through the real economy/event history;
+- generation neither mutates the economy nor commands NPC work, and it adds no
+  quest-only event, acceptance, reward, dialogue, multi-hop rumour, or generic
+  quest framework.
+
+Milestone 7 is not complete. The practical next slice is a second bounded
+unresolved-condition consumer: surface missing-wood `task_blocked` facts from
+patrol or study as a cared-about woodpile-restock need, resolve it through real
+NPC/player wood supply, define deterministic interested-party death/staleness
+handling, and only then extract the lifecycle shared by two proven consumers.
