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 ✓
