Verification Results

🔍 Remaining Issues (5) - All Confirmed

All 5 issues from Run 15 remain unresolved (as expected with only 1 day elapsed):

Critical Priority (1)

• ❌ RCF API in TypeScript - 38 functions, 2-3 weeks effort

Medium Priority (2)

• ❌ Advanced sequence operations in Java - 4 functions, 1 week effort
• ❌ Advanced sequence operations in C# - 4 functions, 1 week effort

Low Priority (2)

• ❌ Benchmark export in C# - 1 function, 2-3 hours effort
• ❌ Benchmark export in TypeScript - 1 function, 2-3 hours effort

Total remaining: 48 function instances, ~5 weeks effort

✅ Spot-Check: No Regressions

Verified that major resolved implementations remain intact:

• ✅ RCF API in Java (RCFNum.java - 38 functions)
• ✅ RCF API in C# (RCFNum.cs - 38 functions)
• ✅ TypeScript Fixedpoint API (~25 functions)
• ✅ TypeScript Goal API (~17 functions)
• ✅ Java benchmark export (benchmarkToSmtlibString())

All previously resolved issues are still in good standing.
