+    descriptor occurrences, their `trigger_kind`, payload family, and the aggregated
+    `dispatch_descriptor_occurrence_counts` / `dispatch_descriptor_map_counts` summaries instead of

+    `548 Add Building Port01`, `8 Economic Status`, and `43 Company Variable 1` all arriving on
+    `real_packed_nondirect_compact_v1` rows with `trigger_kind = null`, while the count summary
+    reports `Company Variable 1 = 4` occurrences and the other two once each, so the next pass can
+    work from a checked scalable probe rather than ad hoc `inspect-smp` scrapes.
+  - the scalable summary sibling is grounded too:
+    `runtime inspect-compact-event-dispatch-cluster-counts <map-or-dir>` reuses the same analysis
+    but emits only the corpus-level count fields, so the next broader map-install pass no longer
+    needs to wade through every occurrence payload just to compare descriptor or trigger-kind
+    coverage.
   - 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`
