+   - Compile all 9 .ink scripts in `/stages/stage_7/`
+   - Verify syntax correctness
+   - Generate .json output files
+   - Test with game's Ink runtime
+
+2. **Review Implementation Roadmap**
+   - Read `/stages/stage_9_prep/IMPLEMENTATION_ROADMAP.md`
+   - Understand 8 implementation phases
+   - Note priority matrix (must-have vs. nice-to-have)
+
+3. **Setup VM Infrastructure**
+   - Follow `/stages/stage_9_prep/vm_infrastructure_setup.md`
+   - Deploy Docker Compose network
+   - Test connectivity from game VM
+   - Verify all 4 flags work correctly
+
+4. **Begin Stage 9 Assembly**
+   - Room JSON generation (7 rooms)
+   - NPC dialogue integration (9 compiled Ink scripts)
+   - Challenge minigames (RFID, VM, CyberChef)
+   - Objectives system integration
+   - Event orchestration (M2 revelation)
+
+5. **Testing and Iteration**
+   - Critical path playthrough (45-60 minutes)
+   - All endings reachable (6-9 variations)
+   - Educational content validation
