+# Adversary Review — parse phase
+
+REVIEW CADENCE: DEFERRED — comprehensive review happens ONCE after Builder completes,
+not per-gate during build phases.
+
+## Status: PENDING
+Builder has not yet completed the parse phase. No verdicts issued yet.
+
+## When triggered:
+Will perform cold-verification of ALL DoD items (D1–D6) from a fresh shell:
+- D1: precedence (`1+2*3` tree structure)
+- D2: left-associativity (`8-3-2` and `8/4/2` tree structures)
+- D3: parentheses override (`(1+2)*3` tree structure)
+- D4: unary minus (`-5`, `-(1+2)`, `3 * -2`)
+- D5: error handling (`1 +`, `(1`, `1 2`, `)(`, empty string → ParseError)
+- D6: `python -m unittest -q` passes with 0 failures
