Section 04: Verification

Status: Complete Goal: All 13 code journeys score 10.0/10. Full test suite passes. Zero memory leaks. Branch is merge-ready.

Context: After Sections 01-03 fix all systematic codegen issues, this section verifies the results. Any journey below 10.0 triggers a loop back to the relevant section.

Depends on: Sections 01, 02, 03 (all must be complete).

04.1 Re-run All Journeys

  • Re-run all 13 code journeys with fresh LLVM IR (2026-03-16): compiled each .ori file, ran eval + AOT paths, dumped fresh IR via ORI_DUMP_AFTER_LLVM=1, ran extract-metrics.py on each
  • All 13 produce correct output on both eval and AOT backends:

    J1-J13correctPASSPASS
  • No CRITICAL or HIGH findings — all 13 score 10.0/10 with 0 unjustified instructions
  • Scores vs 2026-03-16 baseline:

04.2 Score Validation

  • All 13 journeys score 10.0/10
  • All 7 scoring categories at 10/10 for every journey:
    • Instruction Efficiency: 10/10 (all functions OPTIMAL, 1.0x ratio)
    • ARC Correctness: 10/10 (zero violations)
    • Attributes & Safety: 10/10 (100% compliance on fresh IR)
    • Control Flow: 10/10 (zero defects)
    • IR Quality: 10/10 (zero unjustified instructions)
    • Binary Quality: 10/10 (correct output)
    • Other Findings: 10/10 (no uncategorized findings)
  • Overall average = 10.0/10
  • No journey scores below 10.0 — no loop-back needed

04.3 Leak Verification

  • Build all heap-allocating journey binaries (J05, J09, J10, J13)
  • Run with leak checking (ORI_CHECK_LEAKS=1): zero leaks on all four
  • Zero leaks reported on all four heap-allocating journeys
  • Run valgrind on heap-allocating journeys:
    • J05 closures: 0 errors, 0 bytes in use at exit
    • J09 strings: 0 errors, 0 bytes in use at exit
    • J10 lists: 0 errors, 0 bytes in use at exit
    • J13 iterators: 0 errors, 0 bytes in use at exit
  • Zero valgrind errors (no leaks, no use-after-free, no invalid reads/writes)

04.4 Full Test Suite

  • ./test-all.sh — 12,908 passed, 0 failed, 149 skipped (full suite including spec + AOT)
  • ./clippy-all.sh — zero warnings
  • ./fmt-all.sh — no formatting changes
  • diagnostics/dual-exec-verify.sh — fixed per-test timeouts (-k 5 SIGKILL for WSL2 abort hangs); spec tests verified clean (2026-03-16)
  • cargo b --release && ./test-all.sh — 12,908 passed, 0 failed (2026-03-16)
  • cargo test -p ori_llvm — 1757 passed (453 unit + 1304 AOT), 0 failed

04.R Third Party Review Findings

  • None.
