+  - cross-map probing now gives a better static-analysis lead too:
+    `British Isles.gmp` shows no current `0x00431b20` dispatch-strip rows, `Germany.gmp` stays on
+    `Game Variable 1` plus `Company Variable 3..4`, while `Texas Tea.gmp` adds `Economic Status`

+    runtime-event loader
   - the concrete owner strip above that bundle is grounded now too:
     `0x00433060` is the direct non-direct serializer loop that writes `0x4e99/0x4e9a/0x4e9b`,
     calls `0x00430d70` per live collection row, and sits beside the sibling `0x00433130` size/load
