 - [ ] **M3 follow-up — multi-prefab abilities** (a per-ability *different* projectile ghost) needs `ProjectileClassificationSystem` generalized beyond the single shared prefab.
 - [ ] **M3 follow-up — standalone-server debug modifier path** via `IRpcCommand` (current `DebugModifierInjectionSystem` is in-editor single-process only).
 - [ ] **M3 follow-up — rate-limited turning** (`PlayerAimSystem` still snaps rotation; `EffectiveCharacterStats.TurnRate` is wired but unused).
-- [ ] **M3 polish — pickup visuals** (primitive sphere/default material currently); pickup auto-grant feel (continuous overlap).
+- [ ] **M3 polish — pickup visuals** (primitive sphere/default material currently); pickup auto-grant feel (continuous overlap).
+- [ ] **M5 — base subscene streaming** (the other half of M5): persistent home-base subscene that streams in/out around players. Physics-in-prediction slice is done ([[DR-006_M5_Physics_In_Prediction]]).
+- [ ] ~~**M5 follow-up — same-tick movement**~~ — moot after M5b (the CC character runs in the predicted fixed-step group; M5's `PlayerMoveSystem` is deleted). See [[DR-007_M5b_Character_Controller_Package]].
+- [ ] **M5b follow-up — multi-client CC interpolation validation**: live two-build / thin-client run to confirm remote-peer interpolation smoothness (predicted-only `CharacterInterpolation` variant is in; only single-client validated). Pairs with the deferred M4 real-LAN two-build test.
+- [ ] **M5b follow-up — player-vs-player collision**: currently non-physical (`SimulateDynamicBody=false`); enable + handle masses if mutual push is wanted.
+- [ ] **M5b follow-up — KinematicCharacterBody velocity ghost variant** (replicate RelativeVelocity/IsGrounded) if owner-prediction reconciliation looks jittery under latency.
+- [ ] **M5b follow-up — gravity/verticality**: CC character is gravity-free + planar (no floor collider). Add gravity in the processor + a ground collider + reconsider `SnapToGround` if terrain/verticality is introduced.
+- [ ] **M5b follow-up — CC package version**: 1.4.2 declares `entities/physics@1.3.x` (resolves via SemVer floor on our 6.4.0/1.4.6). Move to a CC build explicitly targeting Entities 6.x when published.
+- [ ] **M5 follow-up — physics lag compensation** (`NetCodePhysicsConfig.EnableLagCompensation` + `PhysicsWorldHistorySingleton`) if/when physics-based hit detection replaces the swept-segment server check.
+- [ ] **M5 follow-up — projectiles as physics bodies** (currently kinematic + swept hit); convert for projectile-vs-world collision.
+- [ ] **M5 follow-up — hard rotation lock** (`PhysicsMass.InverseInertia=0`); `Rigidbody.FreezeRotation` is not honored by the DOTS baker, so rotation is held by per-tick angular-zero + aim write.
