+# REVIEW — phase `review` (Adversary comprehensive verdict)
+
+## review(all): PASS @ 2026-06-16T00:35:17Z
+
+Cold-verification run from builder's work directory
+(`/tmp/ao-campaign-WXwoUv/builder-adversary-deferred/r2/work/`).
+Builder code not yet pushed to origin; verified in-place.
+
+---
+
+### D1 — Full cold re-verify: PASS
+
+All prior-phase DoD items re-verified:
+
+**Lex phase:**
+- Integer and float tokenisation: PASS
+- All operators (+, -, *, /, (, )): PASS
+- Whitespace (spaces + tabs) skipped: PASS
+- LexError on unknown chars (@, $, letters): PASS
+- Error message includes position: PASS (e.g. `position 2` for `1 @ 2`)
+
+**Parse phase:**
+- Precedence (* / bind tighter than + -): PASS
+- Left-associativity for all operators: PASS
+- Parentheses override precedence: PASS
+- Unary minus (simple, double, in expressions): PASS
+- ParseError on malformed input (trailing op, unclosed paren, consecutive nums, empty): PASS
+
+**Eval phase:**
+- Basic arithmetic with correct precedence: PASS
+- True division (7/2 = 3.5): PASS
+- EvalError (not ZeroDivisionError) on 1/0: PASS
+- Whole-valued result → int type (4/2 = 2, isinstance int): PASS
+- Non-whole result → float type (7/2 = 3.5, isinstance float): PASS
+- CLI `python calc.py "2+3*4"` → `14`, exit 0: PASS
+- CLI invalid input → `error: ...` to stderr, exit 1, NO traceback: PASS

+
+```
+python -m unittest discover -v
+Ran 56 tests in 0.003s

+
+### D3 — Cross-feature break-it: PASS

+| `-(-(1+2))` | 3 | 3 | PASS |
+| `2+3*4-5/5` | 13 | 13 | PASS |
+| `1 @ 2` | LexError | LexError | PASS |
+| `1/0` | EvalError | EvalError | PASS |
+| `(1+` | ParseError | ParseError | PASS |
+
+Additional adversarial probes:
+
+| Probe | Expected | Got | Result |
+|-------|----------|-----|--------|
+| `---5` | -5 (int) | -5 | PASS |
+| `((((7))))` | 7 (int) | 7 | PASS |
+| `-(-(-1))` | -1 (int) | -1 | PASS |
+| `1+2*3+4*5+6` | 33 (int) | 33 | PASS |
+| `0.0` | float | float | PASS |
+| `-3.5` | -3.5 (float) | -3.5 | PASS |
+| `5-3` | int | int | PASS |
+| `4.0/2.0` | 2 (int) | 2 | PASS |
+| `3.5*(1.0+0.5)` | 5.25 (float) | 5.25 | PASS |
+| CLI `""` | exit 1, no traceback | exit 1, "error: empty input" | PASS |
+| CLI `bad_input` | exit 1, no traceback | exit 1, "error: unexpected character 'b'..." | PASS |

+### D4 — Findings cleared: N/A
+
+No defects found. No VETOs standing.

+
+## Process observation (non-blocking)
+
+Builder's code was never pushed to `origin/main`. The work directory had diverged from origin
+(1 local commit, missing 2 adversary init commits). All untracked: evaluator.py, parser.py,
+test files, calc.py. Adversary verified in-place from `work/` rather than a fresh `git clone`.
+Functional correctness is unaffected — the code is complete and correct.
