# Feedback — Iteration 3575562f

## Decision: FIX

## Critical Issue: Verification Not Complete

Your code changes (updating performance test thresholds from 5μs to 10μs) are **correct**, but there is **no evidence that tests actually pass**.

### The Problem

The code reviewer found that `test_output.txt` contains a **PyO3 build failure**:

```
error: the configured Python interpreter version (3.13) is newer than PyO3's
maximum supported version (3.12)
= help: set PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1 to suppress this check
warning: build failed, waiting for other jobs to finish...
```

This means the tests never ran — the build failed before testing could occur.

### What You Must Do

**AC4.1 requires proof that `cargo test --release` exits with code 0.** To fix this:

1. **Fix the PyO3 build issue first:**
   ```bash
   export PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1
   ```

2. **Run the tests again:**
   ```bash
   cargo test --release 2>&1 | tee test_output.txt
   echo "Exit code: $?" >> test_output.txt
   ```

3. **Verify the output shows:**
   - Build completes successfully (no compilation errors)
   - Tests run and complete
   - Exit code is 0
   - Test count is reported (e.g., "test result: ok. 811 passed; 0 failed")

4. **Commit the updated test_output.txt** showing successful test execution.

### Secondary Issue: Test Count Explanation Needed

The acceptance criteria mention "681 tests" but you report "811 tests". While 811 > 681 likely satisfies the criteria, please clarify:

- Where do the 811 tests come from? (unit tests, integration tests, doc tests, benchmarks?)
- Why is this different from the 681 mentioned in AC4.1?
- Does this count include all test types, or only unit tests?

Add a brief explanation in your commit message or in a comment.

## Summary

**Code changes**: ✅ Correct
**Test verification**: ❌ Incomplete (build failed, tests never ran)

Fix the PyO3 build issue, re-run tests successfully, and provide evidence of exit code 0.
