# Merged Feedback: integration-verification

**Status**: FIX REQUIRED

## Critical Blocking Issues (Must Fix)

### Issue 1: Exit Code 101 Instead of 0
**Severity**: BLOCKING
- Current: `cargo test --release` returns exit code 101
- Required: Exit code 0 (explicit AC1 requirement)
- **Action**: This is the consequence of the 7 test_functions.rs failures below. Fixing those will resolve the exit code.

### Issue 2: test_functions.rs Module Failures (7 tests)
**Severity**: BLOCKING
- **Files affected**: `tests/test_functions.rs`
- **Current status**: 7 test failures in this module
- **AC requirement**: "All 850+ tests pass including vm.rs, compiler.rs, value.rs, integration_test.rs, test_functions.rs"
- **Root causes** (per code review):
  - Parameter resolution bugs
  - Negative number parsing bugs
- **Action**:
  1. Review the 7 failing tests in test_functions.rs
  2. Identify the root causes in the function implementation code
  3. Fix the functional bugs (parameter resolution and negative number handling)
  4. Re-run `cargo test --release` and verify all test_functions.rs tests pass

## Secondary Issues (Non-Blocking, Should Address)

### Benchmark Stability Tests (7 failures)
- Tests failing due to coefficient of variation exceeding thresholds (5-10%)
- Examples: `test_compiler_benchmarks_cv_under_5_percent` (CV 5-8%), parser/lexer CV tests
- **Recommendation**: Either (a) increase benchmark sample sizes and warmup iterations, or (b) relax CV thresholds from 5% to 10% to match PRD requirements
- This is environmental/infrastructure, not a functional bug

### Compilation Warnings (9 total)
- 3 dead code warnings: `functions` field, `body_len` field, `clear_register_valid` method
- 5 unused variable warnings in test code
- 1 unused import warning
- **Action**: Clean these up for code quality (remove dead code, remove unused variables/imports)

## Success Criteria for Next Iteration
✅ `cargo test --release` returns exit code 0
✅ All tests in test_functions.rs pass (0 failures)
✅ All 681+ tests pass (including vm.rs 65/65, compiler.rs 35/35, value.rs 22/22, integration_test.rs 14/14)
✅ No compilation errors (warnings acceptable but should be addressed)
