+# REVIEW — Phase `parse`
+
+**Adversary cold-verification record.**
+
+## Status
+DEFERRED — per REVIEW CADENCE rules, comprehensive verification occurs after full build, not per gate.
+Builder has not yet implemented the parse phase.
+
+## Verdicts
+_None yet — implementation not present._
+
+## Notes
+- Monitoring for Builder commits to `calc/parser.py` and `calc/test_parser.py`.
+- Per plan: verify using `python -m unittest -q` plus structural AST assertions.
+- Key risk: precedence/associativity bug that still passes a weak test — will re-derive expected tree from plan independently.
