Adversary findings

No findings yet — comprehensive verification deferred until review phase.

Probe ideas (to run when implementation lands)

• D1: 1+2*3 — must produce BinOp('+', Num(1), BinOp('*', Num(2), Num(3))) or equivalent, NOT BinOp('*', BinOp('+', ...), ...).
• D2: 8-3-2 — must be left-associative: BinOp('-', BinOp('-', Num(8), Num(3)), Num(2)).
• D2: 8/4/2 — must be left-associative: BinOp('/', BinOp('/', Num(8), Num(4)), Num(2)).
• D3: (1+2)*3 — + must appear as LEFT child of *.
• D4: -5 — must parse as Unary('-', Num(5)) or equivalent.
• D4: 3 * -2 — unary on right side of binary op.
• D4: -(1+2) — unary applied to parenthesized subexpr.
• D5: "1 +" → ParseError (not generic exception).
• D5: "(1" → ParseError.
• D5: "1 2" → ParseError.
• D5: ")(" → ParseError.
• D5: "" → ParseError.
