+# BUILD_PR_LEVEL_18_2_REMOVE_SAMPLE_LOGIC_FROM_ENGINE
+
+## Purpose
+Remove any sample-specific logic from engine paths to complete Level 18.
+
+## Scope
+- Single purpose: decouple sample logic from engine
+- No feature additions
+
+## Required Changes
+1. Identify sample-specific conditionals, assets, or behaviors inside engine modules.
+2. Move such logic into:
+   - samples/* or games/*
+3. Replace with engine-agnostic interfaces (hooks/adapters) if needed.
+
+## Validation
+- node ./scripts/run-node-tests.mjs
+- npm test
+- Ensure no behavior regressions in samples
+
+## Acceptance
+- Engine contains no sample-specific logic
+- All samples continue to function
