+- [x] Decide home-base **grid 2D vs 3D** before M6 — resolved 2026-06-02: **planar single-level `int2` grid**, CellSize 1.0, 32×32 plot (full 3D/stacked deferred). Locked in `BaseGridMath` — [[DR-008_M5_HomeBase_BaseLayer_Storage]].
 - [ ] 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]].
 - [ ] **M2 follow-up — live interactive fire test** (focused Play Mode: press Space / LMB / RT → predicted projectile + dummy HP drop). The server combat loop + replication are validated; the input→`AbilityFireSystem`→predicted-spawn→classification path is only validated structurally.

 - [ ] **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).
-- [ ] **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 — base/expedition subscene split + streaming (Option C)**: the persistent-space split the locked world design ultimately needs (`SceneSystem.LoadSceneAsync`/`UnloadScene`, per-world load on the listen-server, enter-expedition/return-to-base transition). Deferred to its own world-architecture milestone — M6/M7 only need the anchor + grid, now done ([[DR-008_M5_HomeBase_BaseLayer_Storage]]). The physics-in-prediction + base-layer slices of M5 are done ([[DR-006_M5_Physics_In_Prediction]], [[DR-008_M5_HomeBase_BaseLayer_Storage]]).
+- [ ] **M5 follow-up — shared-storage disk persistence** (host-only): runtime structures don't exist until M6, so nothing to save yet; add a thin per-record serialization slice (replayed through M6's placement path) after M6. `BaseAnchor`/`StorageEntry` are already flat/serialization-friendly.
+- [ ] **M5 follow-up — storage interaction polish**: proximity gate the deposit/withdraw (the container carries `HitRadius`); real item/UI model beyond the fixed test item; multi-writer ordering beyond first-come server apply.
+- [ ] **M5 follow-up — multi-client shared storage**: validate two clients see identical shared-storage buffer state (pairs with the deferred M5b multi-client interpolation + M4 two-build tests).
+- [ ] **M5 follow-up — home-base visuals**: only an editor plot-bounds gizmo + a placeholder primitive container today; real ground/walls/structures arrive with M6.
 - [ ] ~~**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.
