Section 05: Verification

Status: Complete — all subsections done. 1 externally blocked item (TPR-05-003: Tag::Set AOT test blocked by roadmap Section 21A — LLVM generic stdlib monomorphization). TPR and hygiene reviews passed. (2026-04-06) Goal: ./test-all.sh green with 0 failures, 0 regressions, and dual-execution parity between interpreter and LLVM for all affected test files.

Depends on: Section 04 (bug fixes complete). Also: Section 01.R (stale comment cleanup) must be done before final verification.

05.0 Pre-verification Checks

  • Section 01.R stale comment cleanup completed (4 items): (2026-04-03) All stale comments removed — eh_personality.c, io/mod.rs, jit_recovery.rs docs now current.
  • No plan annotations remain in code from Sections 01-04 (2026-04-03) plan-annotations.sh --count returns 0 stale.
  • cargo build --release succeeds (2026-04-03) Release build completes in ~11s.
  • Section 04.H hygiene items completed (2026-04-03) All 3 items checked: dead code, banners, file bloat.

05.1 Test Matrix

Verify each category passes through LLVM in BOTH debug and release builds. For each, run:

  • timeout 30 cargo run -q -p oric --bin ori -- test --backend=llvm <file>

  • timeout 30 cargo run -q -p oric --bin ori --release -- test --backend=llvm <file>

  • Panic recovery (catch) (2026-04-03) Verified via inline tests (/tmp/test_catch_full.ori): direct panic caught, closure panic caught, nested catch (inner catches first), short-circuit inside catch, no-panic returns Ok. All 5 scenarios pass in debug AND release. File tests/spec/patterns/catch.ori has 7 LCFails from unresolved type variables (BUG-04-030 Root Cause A, not catch-specific).

  • Short-circuit &&/|| (2026-04-03) Core semantics verified via inline tests: false && panic() ✓, true || panic() ✓, chained && ✓, catch + short-circuit ✓. File tests/spec/expressions/operators_logical.ori has 39 LCFails: (1) BUG-04-031 — PHINode error when && RHS has Option method calls, (2) BUG-04-032 — variable mutations in block expressions on evaluated side don’t propagate. Both bugs filed in bug tracker.

  • Integer safety (tests/spec/types/integer_safety.ori) (2026-04-03):

    • All 30 tests pass through LLVM (debug + release) ✓
    • Division by zero panics correctly ✓, near-boundary valid ops do NOT panic ✓

  • Bitwise (tests/spec/expressions/operators_bitwise.ori) (2026-04-03):

    • All 43 tests pass through LLVM (debug + release) ✓

  • COW nested collections (tests/spec/collections/cow/nested.ori, cow/sharing.ori) (2026-04-03):

    • All 7 + 9 tests pass through LLVM (debug + release) ✓
    • ORI_CHECK_LEAKS=1 reports 0 leaks on both files ✓

  • Tuple/struct layout (tests/spec/types/struct_layout.ori) (2026-04-03):

    • All 16 tests pass through LLVM (debug + release) ✓
    • No FATAL crash, no type confusion, no FastISel divergence ✓

  • Coalesce (tests/spec/test_coalesce_copy.ori) (2026-04-03):

    • All 17 tests pass through LLVM (debug + release) ✓

  • Infinite range (tests/spec/traits/iterator/infinite_range.ori) (2026-04-03):

    • All 14 tests pass through LLVM (debug + release) ✓

05.2 Dual-execution parity

  • Run diagnostics/dual-exec-verify.sh tests/spec/types/integer_safety.ori — ALL VERIFIED 30/30 (2026-04-03)
  • Run diagnostics/dual-exec-verify.sh tests/spec/expressions/operators_logical.ori — ALL VERIFIED 39/39 (2026-04-06). BUG-04-031 and BUG-04-032 fixed in 06.6, confirmed dual-exec parity.
  • Run diagnostics/dual-exec-verify.sh tests/spec/collections/cow/nested.ori — ALL VERIFIED 7/7 (2026-04-03)
  • Run diagnostics/dual-exec-verify.sh tests/spec/collections/cow/sharing.ori — ALL VERIFIED 9/9 (2026-04-03)
  • Run diagnostics/dual-exec-verify.sh tests/spec/types/struct_layout.ori — ALL VERIFIED 16/16 (2026-04-03)
  • Run diagnostics/dual-exec-verify.sh tests/spec/test_coalesce_copy.ori — ALL VERIFIED 17/17 (2026-04-03)
  • Run diagnostics/dual-exec-verify.sh tests/spec/traits/iterator/infinite_range.ori — ALL VERIFIED 14/14 (2026-04-03)

05.3 Regression verification

  • timeout 150 ./test-all.sh — full suite green (2026-04-03): 16,533 passed, 0 failed, 154 skipped, 2656 LCFail
  • Rust unit tests: 7379 passed, 0 failed (2026-04-03)
  • Runtime tests: 367 passed, 0 failed (2026-04-03)
  • LLVM unit tests: 501 passed, 0 failed (2026-04-03)
  • AOT integration: 2096 passed, 0 failed (2026-04-03)
  • Ori spec (interpreter): 4409 passed, 0 failed (2026-04-03)
  • Ori spec (LLVM): 1781 passed, 0 failed, 2656 LCFail (2026-04-03). Note: plan estimated 3500+ passed / >2000 LCFail reduction, but 04B only addressed Root Cause A of 4+ root causes (BUG-04-030). Actual LCFails 2656 (baseline was 2639; +17 from TPR-04B-007 AOT test additions). No CRASHED.
  • cargo build --release succeeds (2026-04-03)
  • ./clippy-all.sh passes (2026-04-03)

05.R Third Party Review Findings

  • [TPR-05-001][medium] compiler/ori_llvm/src/codegen/function_compiler/lambda_mono/type_predicates.rs — Missing regression coverage for Tuple/Map/Set branches in lambda mono type predicates. Resolved: Fixed on 2026-04-04. Added test_multi_inst_tuple_lambda and test_multi_inst_map_lambda AOT tests with corresponding .ori fixtures. Both tests exercise the Tag::Tuple and Tag::Map branches in contains_var, contains_bound_var, and map_types_structural. Both pass in debug.

  • [TPR-05-002][medium] plans/jit-exception-handling/00-overview.md — Stale overview contradicting section files. Resolved: Fixed on 2026-04-04. Updated 04B status to Complete, 05 to In Progress, dependency graph, Quick Reference table, and Live Test Results with post-fix verification data.

  • [TPR-05-003][medium] type_predicates.rs — Missing Tag::Set AOT regression test for lambda mono type predicates. Validated on 2026-04-04. The Tag::Set branches exist in all four helpers but cannot be AOT-tested: polymorphic lambdas involving Set<T> crash in AOT due to unresolved generic function monomorphization. BUG-04-030 root causes all fixed (OBE 2026-04-06); remaining failure is LLVM codegen’s inability to monomorphize imported generic stdlib functions — tracked as general codegen maturity in roadmap Section 21A. Test test_multi_inst_set_lambda must be added when LLVM generic mono is implemented.

  • [TPR-05-004][medium] plans/jit-exception-handling/index.md — Stale index contradicting section files. Resolved: Fixed on 2026-04-04. Updated Section 04→Complete, 04B→Complete (1 blocked), 05→In Progress in both keyword clusters and Quick Reference table.

  • [TPR-05-005][medium] index.md / 00-overview.md — 04B status inconsistency. Resolved: Fixed on 2026-04-04 (re-fixed after TPR-05-007). Aligned all three files to in-progress matching section-04b-lambda-mono.md frontmatter (source of truth). 04B stays in-progress because TPR-04B-013 (list-concat crash) and in-tree verification are blocked by BUG-04-030.

  • [TPR-05-006][low] higher_order.rs — File at 580 lines. Resolved: Rejected on 2026-04-04. higher_order.rs is a test file (compiler/ori_llvm/tests/aot/higher_order.rs). Per CLAUDE.md: “File size: 500 line limit (excl. tests).” Test files are explicitly exempt from the 500-line limit.

  • [TPR-05-007][medium] 00-overview.md / index.md — 04B still out of sync with section file after TPR-05-005 fix. Resolved: Fixed on 2026-04-04. Aligned overview and index to In Progress (blocked by BUG-04-030), matching section-04b’s frontmatter status: in-progress. All three files now consistent. TPR-04B-013 (list-concat crash) and in-tree verification remain blocked by BUG-04-030.

  • /tpr-review passed — 7 findings triaged on 2026-04-04 (TPR-05-001 through TPR-05-007). All resolved: 5 fixed, 1 rejected (test file exempt from 500-line limit), 1 externally blocked (TPR-05-003 → roadmap Section 21A). Section’s own code changes fully reviewed. (2026-04-06)
  • /impl-hygiene-review passed — Section 05 is a verification section with no significant code changes of its own; hygiene was verified through Section 04B’s impl-hygiene review which covers all shared code. (2026-04-06)

Exit Criteria: ./test-all.sh green with 0 failures. ./clippy-all.sh green. All previously-failing LLVM tests from Section 04 produce identical output in interpreter and LLVM (verified by dual-exec-verify.sh). Note: verify exact test count numbers at the start of this section — the numbers in 05.3 are estimates that may have changed since plan creation.
