+# STATUS — phase: lex (Builder)
+
+## DONE
+
+All gates verified PASS by Adversary @2026-06-15T01:35:56Z.
+
+## Gate: D1, D2, D3, D4 — PASS
+
+### WHAT is claimed
+All four gates D1–D4 are implemented and tested.
+
+### HOW to verify (run from a fresh clone)
+
+```bash
+cd <repo>
+python -m unittest -q
+```
+Expected: 22 tests, 0 failures, 0 errors.
+
+```bash
+python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('42')])"
+```
+Expected: `[('NUMBER', 42), ('EOF', None)]`
+
+```bash
+python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('3.14')])"
+```
+Expected: `[('NUMBER', 3.14), ('EOF', None)]`
+
+```bash
+python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('.5')])"
+```
+Expected: `[('NUMBER', 0.5), ('EOF', None)]`
+
+```bash
+python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('10.')])"
+```
+Expected: `[('NUMBER', 10.0), ('EOF', None)]`
+
+```bash
+python -c "from calc.lexer import tokenize; print([t.kind for t in tokenize('1+2*3')])"
+```
+Expected: `['NUMBER', 'PLUS', 'NUMBER', 'STAR', 'NUMBER', 'EOF']`
+
+```bash
+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)]`
+
+```bash
+python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"
+```
+Expected: raises `calc.lexer.LexError: unexpected character '@' at position 2`

+
+### Files
+- `calc/__init__.py` — empty package marker
+- `calc/lexer.py` — Token dataclass, LexError, tokenize()
+- `calc/test_lexer.py` — 22 unittest cases covering D1–D3
+
+### Gate checklist
+- D1 (numbers): PASS @2026-06-15T01:35:56Z
+- D2 (operators & parens): PASS @2026-06-15T01:35:56Z
+- D3 (whitespace & errors): PASS @2026-06-15T01:35:56Z
+- D4 (tests green): PASS @2026-06-15T01:35:56Z
+
+## Informational (non-blocking)
+- F1: lone `.` raises `ValueError` not `LexError` — not required by DoD, noted for future phases
