+# REVIEW — Phase `parse`
+
+Adversary: cold-verification log. One entry per gate per pass.
+
+## Verdicts
+
+### parse/D1: PASS @2026-06-15T04:03Z
+Cold-ran at commit e9a5152.
+```
+parse(tokenize('1+2*3')) → BinOp('+', Num(1), BinOp('*', Num(2), Num(3)))  ✓
+```
+`*` binds tighter than `+` — tree structure matches plan requirement. Independently verified extra cases:
+`1*2+3*4` → `BinOp('+', BinOp('*', Num(1), Num(2)), BinOp('*', Num(3), Num(4)))` ✓
+
+### parse/D2: PASS @2026-06-15T04:03Z
+```
+parse(tokenize('8-3-2')) → BinOp('-', BinOp('-', Num(8), Num(3)), Num(2))  ✓
+parse(tokenize('8/4/2')) → BinOp('/', BinOp('/', Num(8), Num(4)), Num(2))  ✓
+```
+Left-associativity confirmed by `while` loop in `_expr`/`_term` (re-read code). Extra probe:
+`1+2+3+4` → `BinOp('+', BinOp('+', BinOp('+', Num(1), Num(2)), Num(3)), Num(4))` ✓
+
+### parse/D3: PASS @2026-06-15T04:03Z
+```
+parse(tokenize('(1+2)*3')) → BinOp('*', BinOp('+', Num(1), Num(2)), Num(3))  ✓
+```
+Double paren `((3))` → `Num(3)` ✓
+
+### parse/D4: PASS @2026-06-15T04:03Z
+```
+parse(tokenize('-5'))     → Unary('-', Num(5))  ✓
+parse(tokenize('-(1+2)')) → Unary('-', BinOp('+', Num(1), Num(2)))  ✓
+parse(tokenize('3 * -2')) → BinOp('*', Num(3), Unary('-', Num(2)))  ✓
+```
+Extra probes: `--5` → `Unary('-', Unary('-', Num(5)))` ✓; `1+-2` → `BinOp('+', Num(1), Unary('-', Num(2)))` ✓;
+`-1-2` → `BinOp('-', Unary('-', Num(1)), Num(2))` ✓; `-(-(1))` → `Unary('-', Unary('-', Num(1)))` ✓
+
+### parse/D5: PASS @2026-06-15T04:03Z
+All five plan-mandated malformed inputs raise `ParseError` (not TypeError/ValueError/IndexError):
+```
+'1 +'  → ParseError: unexpected end of input  ✓
+'(1'   → ParseError: expected RPAREN, got 'EOF' (None)  ✓
+'1 2'  → ParseError: unexpected token 'NUMBER' (2)  ✓
+')('   → ParseError: unexpected token 'RPAREN' (')')  ✓
+''     → ParseError: unexpected end of input  ✓
+```
+Extra probes all raise ParseError: `* 1`, `1 * `, `()`, `1 + ()`, `1)`, `(1+2` — all correct.
+
+### parse/D6: PASS @2026-06-15T04:03Z
+```
+$ python -m unittest -q
+Ran 34 tests in 0.001s
+OK
+```
+34 tests (14 lex + 20 parse), 0 failures.

+## Adversary findings

+_(none — no defects found; no veto)_
+
+## Summary
+
+All six DoD gates PASS. No veto. Builder may write "## DONE" to STATUS-parse.md.
