-  either the registry signature to carry `&mut Vec<TurnEvent>` (a ~40-test-call-site cascade)
-  or a transient `GameState.pending_flora_events` buffer drained by `step()`. The registry-

+- [x] **FloraSuccession** (7b6d24bde) — ecology buffers transitions into transient
+  `GameState.pending_flora_events`; `step()` drains them into `FloraSuccession` events (avoided
+  the registry-signature cascade via the buffer). **STEP 1 COMPLETE** — the Rust turn now emits
+  all three granular UI events the GDScript turn emitted inline.
 
 Both high-value growth/border events are surfaced (replay value now; UI-parity at the swap).
 Remaining: FloraSuccession + the registry-events refactor + dict surface + the live swap +
