### FINDING-1 — float literal not normalized to int [OPEN]
**Filed:** 2026-06-16T00:54:18Z
**Phase:** eval/D3 (result type consistency)

**Repro:**
```bash
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.
