 ## Purpose
-Enable sharing of overlay profiles and presets between users.
+Perform full validation sweep of Level 22 overlay features.
 
 ## Scope
-- Generate shareable profile packages (JSON)
-- Import shared profiles safely
-- Provide version compatibility checks
+- Validate interactions, gestures, contextual input
+- Validate adaptive UI, persistence, presets, sharing
+- Ensure no regressions across earlier levels
 
 ## Test Steps
-1. Export share package
-2. Import into another environment
-3. Validate correct behavior
+1. Execute full runtime test suite
+2. Validate cross-feature compatibility
+3. Confirm stability under mixed usage
 
 ## Expected
-- Profiles transferable between users
-- Safe import with validation
+- All Level 22 features operate together correctly
+- No regressions introduced
