STATUS — phase lex
DONE
All gates D1–D4 Adversary-verified PASS @2026-06-15T04:17:47Z. No vetoes. Phase complete.
All gates D1–D4 implemented and locally verified. Claiming all four simultaneously.
D1 — numbers (CLAIMED)
WHAT: tokenize("42") → [NUMBER(42), EOF]; floats 3.14, .5, 10. each yield one NUMBER token with numeric value (int or float).
HOW:
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('42')])"
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('3.14')])"
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('.5')])"
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('10.')])"
EXPECTED:
[('NUMBER', 42), ('EOF', None)]
[('NUMBER', 3.14), ('EOF', None)]
[('NUMBER', 0.5), ('EOF', None)]
[('NUMBER', 10.0), ('EOF', None)]
WHERE: calc/lexer.py — _NUMBER_RE + tokenize() function.
D2 — operators & parens (CLAIMED)
WHAT: + - * / ( ) each tokenize to the right kind; tokenize("1+2*3") yields NUMBER PLUS NUMBER STAR NUMBER EOF.
HOW:
python -c "from calc.lexer import tokenize; print([t.kind for t in tokenize('1+2*3')])"
EXPECTED:
['NUMBER', 'PLUS', 'NUMBER', 'STAR', 'NUMBER', 'EOF']
WHERE: calc/lexer.py — _SINGLE dict.
D3 — whitespace & errors (CLAIMED)
WHAT: Spaces/tabs skipped; invalid char raises LexError with offending char and position.
HOW:
python -c "from calc.lexer import tokenize; print([t.kind for t in tokenize(' 12 + 3 ')])"
python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"
EXPECTED:
- First:
['NUMBER', 'PLUS', 'NUMBER', 'EOF'] - Second: raises
calc.lexer.LexError: unexpected character '@' at position 2
WHERE: calc/lexer.py — whitespace skip + LexError raise in tokenize().
D4 — tests green (CLAIMED)
WHAT: python -m unittest -q runs 17 tests, 0 failures.
HOW:
python -m unittest -q
EXPECTED:
----------------------------------------------------------------------
Ran 17 tests in 0.000s
OK
WHERE: calc/test_lexer.py — 17 tests across 4 test classes covering D1–D3.
Cold-verify commands (from plan)
python -m unittest -q
python -c "from calc.lexer import tokenize; print([(t.kind,t.value) for t in tokenize('3.5*(1-2)')])"
python -c "from calc.lexer import tokenize; tokenize('1 @ 2')"
Expected outputs:
Ran 17 tests ... OK[('NUMBER', 3.5), ('STAR', None), ('LPAREN', None), ('NUMBER', 1), ('MINUS', None), ('NUMBER', 2), ('RPAREN', None), ('EOF', None)]- Raises
LexError: unexpected character '@' at position 2
