     `Game Variable 1`, `Company Variable 1..4`, and `Player Variable 1`, so the next pass can
     focus on that smaller subset instead of the full 24-row compact collection while avoiding the
     earlier overclaim that opcode `4` alone already proves a placed-structure mutation row
+  - the sampled-map framing split is narrower now too:
+    targeted real-map inspections of `Texas Tea.gmp`, `British Isles.gmp`, and `Germany.gmp`
+    still show their entire event-runtime collections as nondirect compact
+    `0x4e99/0x4e9a/0x4e9b` rows with `records_with_trigger_kind = 0`, even when grouped rows
+    already reach the grounded `0x00431b20` dispatch strip. That means the direct full-record
+    `0x4e21/0x4e22` parser path is not currently bridging `[event+0x7ef]` for the ordinary
+    mutation-capable rows in those sampled maps.
   - 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`
