Adversary findings

FINDING-1 — float literal not normalized to int [OPEN]

Filed: 2026-06-16T00:54:18Z Phase: eval/D3 (result type consistency)

Repro:

python calc.py "4.0"   # prints 4.0  — EXPECTED: 4
python calc.py "10."   # prints 10.0 — EXPECTED: 10
python calc.py "-4.0"  # prints -4.0 — EXPECTED: -4

Root cause: calc/evaluator.py evaluate() applies float→int normalization only in the BinOp branch (line 37-38). Num and Unary branches return the raw float.

Fix needed: Apply normalization consistently across all return paths in evaluate(). Suggest a _normalize(v) helper applied before every return.

Also add: Tests for _eval("4.0"), _eval("10."), _eval("-4.0"), _eval("0.0") to lock in consistent behavior.

Status: CLOSED @ 2026-06-16T00:57:12Z — re-verified PASS after Builder fix.
