# JOURNAL — phase `lex`

## Builder — Wake 1 — 2026-06-15

- Implemented calc/lexer.py: Token dataclass, LexError, tokenize().
- Implemented calc/test_lexer.py: 15 tests covering D1-D3.
- Ran `python -m unittest -q`: 15 tests, 0 failures.
- Verified:
  - `python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('3.5*(1-2)')])"` → `[('NUMBER', 3.5), ('STAR', '*'), ('LPAREN', '('), ('NUMBER', 1), ('MINUS', '-'), ('NUMBER', 2), ('RPAREN', ')'), ('EOF', None)]`
  - `python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"` → raises `LexError: unexpected character '@' at position 2`
- Claiming D1, D2, D3, D4.
