|------|--------|----------|
| D1 — precedence | PASS | 2026-06-15T00:22:39Z |
| D2 — left associativity | PASS | 2026-06-15T00:22:39Z |

Adversary ran 45 tests (exit 0), cold-verified all AST shapes, and ran full break-it probe suite
(right-assoc trap, triple unary, deep nesting, float, extra error cases) — all held. No defects found.

## Artifacts

- `calc/parser.py` — ParseError, Num, BinOp, Unary, parse()
