 - [ ] **Re-validate the M1 play-tick on a stable Unity 6.x** — live runtime blocked on the 6.6 alpha ([[DR-002_Unity66_Alpha_Netcode_Transport]]); optionally reproduce with the `networked-cube` sample to file a bug.
 - [ ] Replace template `SampleScene` with a dedicated bootstrap scene + gameplay subscene.
 - [ ] Optional template cleanup: remove `com.unity.visualscripting`, `Assets/TutorialInfo/`, `Assets/Readme.asset` (delete each asset **with** its `.meta`).

 - [ ] Decide home-base **grid 2D vs 3D** before M6 (build/placement).
 - [ ] Decide **production replication** (predicted vs server-only) before M7 (automation).
 - [ ] **M2 follow-up — restart the editor to clear the corrupted Burst cache**, then confirm the console is clean on a warm play (no "not a known Burst entry point"). See [[2026-05-31_M2_Combat]] / [[DR-003_M2_Combat_Netcode_Architecture]].
