+
+## Gates

+- D2 — operators & parens: PASS (Adversary verified)
+- D3 — whitespace & errors: PASS (Adversary verified)
+- D4 — tests green: PASS (Adversary verified)

+## Verification commands (re-run from a fresh clone)
+
+```bash
+# D4 — all tests pass
+python -m unittest -q
+# Expected: 18 tests, 0 failures, exit 0
+
+# D2 — operator/paren sequence
+python -c "from calc.lexer import tokenize; print([t.kind for t in tokenize('1+2*3')])"
+# Expected: ['NUMBER', 'PLUS', 'NUMBER', 'STAR', 'NUMBER', 'EOF']
+
+# D1 + D2 + D3 combined
+python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('3.5*(1-2)')])"
+# Expected: [('NUMBER', 3.5), ('STAR', None), ('LPAREN', None), ('NUMBER', 1), ('MINUS', None), ('NUMBER', 2), ('RPAREN', None), ('EOF', None)]
+
+# D3 — LexError on invalid char
+python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"
+# Expected: raises calc.lexer.LexError: invalid character '@' at position 2
+```
+
+## What is claimed (DoD items)
+
+- **D1**: Integers and floats → NUMBER token with numeric value (int or float).
+  - `tokenize("42")` → `[NUMBER(42), EOF]` (int)
+  - `tokenize("3.14")` → `[NUMBER(3.14), EOF]` (float)
+  - `tokenize(".5")` → `[NUMBER(0.5), EOF]` (float)
+  - `tokenize("10.")` → `[NUMBER(10.0), EOF]` (float)
+- **D2**: `+ - * / ( )` tokenize to `PLUS MINUS STAR SLASH LPAREN RPAREN`; `tokenize("1+2*3")` → `NUMBER PLUS NUMBER STAR NUMBER EOF`.
+- **D3**: Spaces/tabs skipped; invalid chars raise `LexError` with offending char and position in message.
+  - `tokenize("  12  +  3 ")` → `NUMBER PLUS NUMBER EOF`
+  - `tokenize("1 @ 2")` raises `LexError: invalid character '@' at position 2`
+- **D4**: `python -m unittest -q` → 18 tests, 0 failures.
