 Status: **Living document — work in progress, started 2026-05-08.**
 
+**Progress (2026-05-08):** Tasks 1-8 ✅ complete. Tasks 1-5 landed foundation types + WbMeshAdapter stub. Task 6 obsoleted by `DefaultDatReaderWriter` discovery (Adjustment 1). Task 7 wired the adapter into `GameWindow` lifecycle behind the flag. Task 8 CLAUDE.md pointer was done preemptively in commit `506b86b`. **Next: Task 9** — route `InstancedMeshRenderer.EnsureUploaded` through `WbMeshAdapter` when flag is on (first behavioral change; flag-on render path will skip static scenery until Task 22 wires `WbDrawDispatcher`).
