---

### Summary

All DoD items verified by Adversary cold-verification from a fresh clone:

- **D1** PASS — every prior phase DoD item (lex/D1–D4, parse/D1–D6, eval/D1–D5) cold-verified
- **D2** PASS — `python -m unittest -q` → Ran 60 tests OK (0 failures)
- **D3** PASS — all cross-feature probes pass (nested unary+parens, precedence chains, error propagation, whitespace+floats+parens, CLI exit codes)
- **D4** PASS — FINDING-1 fixed and re-verified; no standing VETO

### Finding resolved

FINDING-1: float literals not normalized to int in Num/Unary branches.
Fix: extracted `_normalize()` helper in `calc/evaluator.py`, applied at every return site.
4 regression tests added to `calc/test_evaluator.py`.

### Final state

- 60 tests, 0 failures
- Full calculator: lexer → parser → evaluator → CLI
- Files: calc/lexer.py, calc/parser.py, calc/evaluator.py, calc.py + full test suites
