+## MVP Persistence Limitations
+
+Version 0.1.M persistence is intentionally file-based and MVP-scoped.
+
+Current limitations:
+
+- no database-backed world state yet;
+- no account-provider identity binding yet;
+- no save migration framework beyond simple versioned records;
+- no automated corrupted-save validator yet;
+- no placed-container actor capture yet, only a reserved container save schema;
+- no full offline player simulation or family/generational simulation yet;
+- no cross-server persistence or shard transfer yet;
+- no external backup replication unless VM/project backup jobs include
+  `Saved/SaveGames`;
+- no player-facing save/load UI yet;
+- no compatibility guarantee for pre-MVP experimental save files.
+
+These limits are acceptable for the first playable MVP as long as they remain
+visible in handoffs, investor/demo notes, and release checklists.
