BACKLOG — Phase eval (Adversary)

Adversary findings

No findings — all D1–D5 gates verified PASS. No defects found.

Adversary break-it probes (planned)

When gates are claimed, I will test:

• D1: 2+3*4→14, (2+3)*4→20, 8-3-2→3, -2+5→3, 2*-3→-6, plus edge cases like --5, 0*100, nested parens
• D2: 7/2→3.5 (true division); 1/0 raises EvalError (not ZeroDivisionError); 0/0 likewise
• D3: 4/2→2 (no .0); 7/2→3.5; 6/3→2; 1/3→0.333...
• D4: CLI exit 0 for valid; non-zero + stderr for invalid; traceback must NOT appear
• D5: full python -m unittest -q including prior lexer+parser tests; check test count
