Review UPLC-CAPE submission: factorial

[Unisay]

#29

[Unisay]

✅ Integration Complete

The Plutarch factorial submission from PR #29 has been successfully integrated into the main codebase.

What Was Done

🔄 Clean Integration Strategy:

• Cherry-picked only the submission files from Add entry Factorial for Plutarch implementation #29 to avoid merge conflicts
• Created new integration branch integrate-plutarch-factorial
• Ran cape submission measure --all for consistent measurement environment
• Regenerated all reports with factorial comparison
• Fixed Haskell formatting issue with ImportQualifiedPost extension

📊 Performance Results:

• Added: submissions/factorial/Plutarch_1.10.1_SeungheonOh/ with complete submission data
• Benchmark: factorial(10) computation
• Performance: 7.85M CPU units, 28.36K memory units, 42 bytes script size
• Implementation: Uses fix point combinators and demonstrates "builtin casing" power

Pull Requests

• Superseded: Add entry Factorial for Plutarch implementation #29 (original submission) - will be closed due to merge conflicts
• New: feat(factorial): integrate Plutarch 1.10.1 submission #33 - Clean integration PR ready for review and merge
  • Link: feat(factorial): integrate Plutarch 1.10.1 submission #33
  • Status: ✅ Ready for merge
  • Contains: Submission files + updated measurements + regenerated reports

Performance Comparison

The factorial benchmark now includes both available submissions:

Compiler	CPU Units	Memory Units	Script Size	Term Size	Winner
Plinth 1.52.0.0	5.86M	21.75K	37	29	⭐ Best
Plutarch 1.10.1	7.85M	28.36K	42	35

Key Insights:

• Plinth outperforms Plutarch across all metrics for factorial
• Much more efficient than fibonacci (M vs B scale difference)
• Both implementations demonstrate different optimization approaches

Verification

• ✅ Main Index: Shows "factorial (2 submissions)"
• ✅ Benchmark Page: Displays comparison table with both submissions
• ✅ Performance Charts: Generated factorial CPU/memory/size charts
• ✅ Schema Compliance: All submission files validated
• ✅ Formatting: Fixed Haskell source with ImportQualifiedPost extension

Next Step: Merge PR #33 to complete the integration.

🎯 Review Complete - The factorial submission is successfully integrated and ready for merge.

cc @SeungheonOh - thank you for the contribution demonstrating builtin casing power! 🚀
