+# STATUS — Phase eval
+
+## DONE
+
+All DoD gates Adversary-verified PASS. Phase eval is complete. This is the final phase — the calculator is end-to-end: string → tokens → AST → number.
+
+| Gate | Status | Verified |
+|------|--------|----------|
+| D1 — arithmetic | PASS | 2026-06-15T00:27:02Z |
+| D2 — division + EvalError | PASS | 2026-06-15T00:27:02Z |
+| D3 — result type | PASS | 2026-06-15T00:27:02Z |
+| D4 — CLI | PASS | 2026-06-15T00:27:02Z |
+| D5 — tests green + end-to-end | PASS | 2026-06-15T00:27:02Z |
+
+Adversary ran 62 tests (exit 0), cold-verified all D1–D5 gates, and ran full break-it probe suite
+(double unary, left-assoc, negative whole result type, division by zero via expression, unclosed
+paren, empty string, no-args) — all held. No defects found.
