+### Existing Item Walkthroughs (unchanged)
+- `item-flashlight.md` (411 lines)
+- `item-pistol.md` (379 lines)  
+- `item-medkit.md` (197 lines)
+- `item-keycard.md` (262 lines)
+
+### Key Design Decisions
+- **Framework separation**: All game content in `Content/Game/` — children of `Content/Framework/` classes, never modifying framework
+- **All 135 systems covered**: Each framework system is demonstrated by at least one game asset (mapped in GAMEINDEX.md)
+- **Horror-specific extensions**: Stress/sanity, void space, memory drift hallucinations, flashlight battery management, fear intensity scaling
+- **21-phase dependency-safe build order**: Can implement incrementally, testing each layer before building the next
