## eval/D1: PASS @2026-06-15T04:12Z

Cold re-run: all 5 plan expressions correct.
- `2+3*4` → `14` ✓
- `(2+3)*4` → `20` ✓
- `8-3-2` → `3` ✓
- `-2+5` → `3` ✓
- `2*-3` → `-6` ✓

Additional adversarial: `((2+3)*4-10)/2` → `5`, `-(-3)` → `3`, `1-2*3+4` → `-1` — all correct.
D1Arithmetic suite: 8 tests, OK.

## eval/D2: PASS @2026-06-15T04:12Z

Cold re-run:
- `7/2` → `3.5` (true division) ✓
- `1/0` → `EvalError("division by zero")` raised, not bare `ZeroDivisionError` ✓
- `5/(3-3)` → `EvalError` (expression-based zero denominator) ✓
- `EvalError.__bases__` = `(Exception,)` — not a subclass of `ZeroDivisionError` ✓

D2Division suite: 5 tests, OK.

## eval/D3: PASS @2026-06-15T04:12Z

Cold re-run:
- `python calc.py "4/2"` → `2` (no trailing `.0`) ✓
- `python calc.py "7/2"` → `3.5` ✓
- `_format(5)` → `'5'`, `_format(5.0)` → `'5'`, `_format(3.5)` → `'3.5'` ✓
- Integer inputs (e.g. `2+3`) return `int` from `evaluate()`, format correctly ✓

D3ResultType suite: 3 tests, OK.

---

## eval/D4: PASS @2026-06-15T04:12Z

Cold re-run:
- `python calc.py "2+3*4"` → stdout `14`, exit 0 ✓
- `python calc.py "(2+3)*4"` → stdout `20`, exit 0 ✓
- `python calc.py "1/0"` → stderr `error: division by zero`, exit 1, stdout empty ✓
- `python calc.py "1 +"` → stderr `error: unexpected token 'EOF' (None)`, exit 1, stdout empty ✓
- No traceback in stderr on error ✓
- No args / too many args → usage to stderr, exit 1 ✓

D4CLI suite: 6 tests, OK.

---

## eval/D5: PASS @2026-06-15T04:12Z

Cold re-run: `python -m unittest -q` → `Ran 66 tests in 0.153s` / `OK`
- Lex tests (21) + parse tests (23) + evaluator/CLI tests (22) all green ✓
- No regressions in prior phases ✓
- Full suite run twice; consistent result ✓

## Summary

All gates D1–D5: **PASS**. No defects. No VETO.
