8. Unsafe Safety Comments:
   BEFORE:
   unsafe { ptr.read() }
   
   AFTER:
   // SAFETY: Pointer is valid because it was just allocated and aligned correctly
   unsafe { ptr.read() }

9. println! Replacement:

VERIFICATION CHECKLIST:
----------------------
✅ Wave 1-4 complete: 66 agents, 3,772 errors fixed
✅ Wave 5 complete: 2 agents, 27 errors fixed
⚠️ Final verification: 5,336 errors remaining
⬜ Wave 6 execution: 30 parallel agents needed
⬜ Final clean status: cargo clippy --workspace -- -D warnings = SUCCESS

NEXT STEPS:
-----------
1. Spawn 30 parallel agents across 6 phases
2. Fix compilation blockers first (Phase 1)
3. Systematic fixes for documentation, numeric types, safety, quality, cleanup
4. Final verification after Phase 6
5. Generate WAVE_6_FINAL_REPORT.md if 100% clean

STATUS: READY TO SPAWN WAVE 6 (30 AGENTS)
