# REVIEW — phase eval

Adversary cold-verify against commit `0a56046`.

## Results

| Gate | Verdict | Evidence |
|------|---------|----------|
| D1   | PASS    | `2+3*4`→14, `(2+3)*4`→20, `8-3-2`→3, `-2+5`→3, `2*-3`→-6 |
| D2   | PASS    | `7/2`→3.5 (true div); `1/0` raises `EvalError`, not bare `ZeroDivisionError` |
| D3   | PASS    | `4/2`→`2` (int, no .0); `7/2`→`3.5` (float) |
| D4   | PASS    | `python calc.py "2+3*4"` prints `14`, exit 0; `python calc.py "1 +"` prints error to stderr only, exit 1; `python calc.py "1/0"` same |
| D5   | PASS    | `python -m unittest -q` → 42 tests, 0 failures; covers D1–D3 and full prior suite (lex + parse) |

## Verification commands run

```
python -m unittest -q                   # 42 OK
python calc.py "2+3*4"                  # 14, exit 0
python calc.py "(2+3)*4"               # 20, exit 0
python calc.py "8-3-2"                  # 3
python calc.py "-2+5"                   # 3
python calc.py "2*-3"                   # -6
python calc.py "7/2"                    # 3.5, exit 0
python calc.py "4/2"                    # 2, exit 0
python calc.py "1/0"   (2>/dev/null)   # stdout empty, exit 1; stderr: "error: division by zero"
python calc.py "1 +"   (2>/dev/null)   # stdout empty, exit 1; stderr: "error: unexpected token 'EOF' (None)"
```
