REVIEW — Phase review

Adversary cold-verification record.

Status

COMPREHENSIVE PASS @2026-06-16T00:21Z — all D1–D4 items verified.

D1 — Full cold re-verify (all prior phase DoD items)

Cold-verified from work-adv clone at commit bfd5972 (post-pull).

Lexer DoD

  • INTEGER: tokenize('42') → [Token('NUMBER', 42), Token('EOF', None)], value is int ✓
  • FLOAT: tokenize('3.14') → [Token('NUMBER', 3.14), Token('EOF', None)] ✓
  • LEADING DOT: tokenize('.5') → Token('NUMBER', 0.5) ✓
  • OPERATORS: tokenize('+-*/()') → PLUS, MINUS, STAR, SLASH, LPAREN, RPAREN, EOF (correct kinds) ✓
  • WHITESPACE: spaces and tabs skipped ✓
  • LexError message contains char + position: unexpected character '$' at position 1 ✓
  • Unknown chars @, $, letters raise LexError ✓

PASS

Parser DoD

  • Single int: parse(tokenize('1')) → Num(1) ✓
  • Single float: parse(tokenize('3.14')) → Num(3.14) ✓
  • BinOp shape: parse(tokenize('1+2')) → BinOp('+', Num(1), Num(2)) ✓
  • Unary shape: parse(tokenize('-5')) → Unary('-', Num(5)) ✓
  • Precedence: parse(tokenize('2+3*4')) → BinOp('+', Num(2), BinOp('*', Num(3), Num(4))) (mul binds tighter) ✓
  • Left-associativity: parse(tokenize('1-2-3')) → BinOp('-', BinOp('-', Num(1), Num(2)), Num(3)) ✓
  • Empty input: raises ParseError ✓
  • Unclosed paren (1+: raises ParseError ✓
  • Two numbers adjacent 1 2: raises ParseError ✓

PASS

Evaluator DoD

  • Arithmetic: 2+3*4→14, (2+3)*4→20, 8-3-2→3, -2+5→3, 2*-3→-6 ✓
  • True division: 7/2→3.5 ✓
  • Division by zero: 1/0 raises EvalError("division by zero"), NOT bare ZeroDivisionError ✓
  • fmt_result: fmt_result(2.0)→'2', fmt_result(3.5)→'3.5', fmt_result(42)→'42' ✓
  • CLI: python calc.py "2+3*4" → stdout 14, exit 0 ✓
  • CLI: python calc.py "(2+3)*4" → stdout 20, exit 0 ✓
  • CLI: python calc.py "7/2" → stdout 3.5, exit 0 ✓
  • CLI: python calc.py "4/2" → stdout 2, exit 0 ✓
  • CLI error: python calc.py "1/0" → stderr error: division by zero, exit 1, no traceback ✓
  • CLI error: python calc.py "1 +" → stderr error: unexpected token 'EOF' (None), exit 1 ✓

PASS

D2 — Full suite green

python -m unittest -v
Ran 64 tests in 0.002s
OK

All 64 tests pass (calc.test_lexer, calc.test_parser, calc.test_evaluator). Zero failures, zero errors.

PASS

D3 — Cross-feature break-it

All tests run independently against the actual CLI and Python API:

Expression Expected Actual Result
-(-(1+2)) 3 3 PASS
2+3*4-5/5 13 13 (raw 13.0, fmt→13) PASS
--5 5 5 PASS
((((3)))) 3 3 PASS
1+2*3+4*5+6 33 33 PASS
( 1.5 + 2.5 ) * 2 8 8 (raw 8.0, fmt→8) PASS
2.5 + ( 3.5 * 2 ) 9.5 9.5 PASS
(1+2)*(3+4) 21 21 PASS

Error propagation:

Input Expected error type Actual Result
1 @ 2 LexError LexError: unexpected character '@' at position 2 PASS
1/0 EvalError EvalError: division by zero (no bare ZeroDivisionError) PASS
(1+ ParseError ParseError: unexpected token 'EOF' (None) PASS
bad input @# CLI exit 1 error: unexpected character 'b' at position 0, exit 1 PASS

CLI exit codes:

  • Valid expressions → exit 0 ✓
  • Invalid expressions (lex/parse/eval errors) → exit 1 ✓
  • No tracebacks on errors ✓

Note: 2+3*4-5/5 raw result is 13.0 (float, because 5/5 returns 1.0), but fmt_result(13.0) → '13' — correct behavior.

No defects found. PASS

D4 — Findings cleared

No findings were filed. No VETO. Nothing to clear.

PASS

OVERALL VERDICT

review(all): PASS @2026-06-16T00:21Z

Comprehensive cold-verification of all D1–D4 from the review phase plan (covering lex, parse, eval, and CLI) passes in full. 64 unit tests green. All cross-feature integration probes pass. No defects, no VETO.

Builder may now write ## DONE to STATUS-review.md.
