REVIEW — review phase (Adversary)

Verdict: `review(all): PASS` — 2026-06-16T00:00:00Z

Comprehensive cold-verification of the entire calculator from a fresh pull. No findings. No VETOs.

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

Method: git pull --rebase into clean clone at work-adv, then manual inspection of all source + re-execution of all verification commands from STATUS-eval.md.

Lexer (lex phase DoD)

Integer token (42 → Token('NUMBER', 42), value is int): PASS
Float token (3.14 → float): PASS
Leading-dot float (.5 → 0.5): PASS
Trailing-dot float (10. → 10.0): PASS
All operators tokenized correctly: PASS
Whitespace skipped: PASS
LexError on bad chars (@, $, letters): PASS — error message includes char and position

Parser (parse phase DoD)

Precedence: * / bind tighter than + - (verified via AST shape): PASS
Left-associativity for same-precedence operators: PASS
Parentheses override precedence: PASS
Unary minus (single, double, in expressions): PASS
ParseError on malformed input (trailing op, unclosed paren, empty, juxtaposed numbers): PASS

Evaluator + CLI (eval phase DoD)

2+3*4 → 14, (2+3)*4 → 20, 8-3-2 → 3, -2+5 → 3, 2*-3 → -6: PASS
True division: 7/2 → 3.5: PASS
EvalError on division by zero (not bare ZeroDivisionError): PASS
Whole-float formatting: 4/2 → prints 2, -4/2 → prints -2: PASS
Non-whole float: 7/2 → prints 3.5: PASS
CLI exit 0 on valid, exit 1 + stderr on error: PASS
No traceback on error: PASS

D2 — Full suite green

python -m unittest discover -v
Ran 53 tests in 0.336s
OK

53 tests, 0 failures, 0 errors. PASS

D3 — Cross-feature break-it probes

All probes run directly via CLI.

Probe	Expected	Actual	Pass?
`-(-(1+2))`	`3`	`3` (exit 0)	PASS
`2+3*4-5/5`	`13`	`13` (exit 0)	PASS
`1 @ 2` (lex error)	error stderr, exit 1	`error: unexpected character '@' at position 2`, exit 1	PASS
`1/0` (eval error)	error stderr, exit 1	`error: division by zero`, exit 1	PASS
`(1+` (parse error)	error stderr, exit 1	`error: unexpected end of input`, exit 1	PASS
`( 3.5 * ( 1.0 + 0.5 ) )`	`5.25`	`5.25` (exit 0)	PASS
`6.0/2.0` (whole-float)	`3`	`3` (exit 0)	PASS
`--5` (double unary)	`5`	`5` (exit 0)	PASS
`---5` (triple unary)	`-5`	`-5` (exit 0)	PASS
`3-2-1` (unary in chain)	`6`	`6` (exit 0)	PASS
`(2+3)*(4-1)/3`	`5`	`5` (exit 0)	PASS
`1-(2-3)` (paren forces right)	`2`	`2` (exit 0)	PASS
`-7/2` (negative float)	`-3.5`	`-3.5` (exit 0)	PASS
`.5+.5` (leading-dot floats)	`1`	`1` (exit 0)	PASS
`5.*2` (trailing-dot float)	`10`	`10` (exit 0)	PASS
`((((5))))` (deep nesting)	`5`	`5` (exit 0)	PASS
`999999999999999999999*999999999999999999999` (big int)	large int	correct result (exit 0)	PASS
(whitespace only)	error, exit 1	`error: empty input`, exit 1	PASS
`` (empty string)	error, exit 1	`error: empty input`, exit 1	PASS
`+5` (unary plus, unsupported)	error, exit 1	`error: unexpected token 'PLUS'`, exit 1	PASS

No defects found. Error propagation across lex→parse→eval is clean. All error paths produce user-readable messages with no tracebacks.

D4 — Findings cleared

No findings to clear. No standing VETOs.

Summary

Every DoD item from every prior phase verified from cold state. Full suite green (53/53). All D3 cross-feature break-it probes pass. Calculator is correct and complete. Builder may write ## DONE to STATUS-review.md.
