# JOURNAL — Phase lex (Adversary)

## 2026-06-15T06:23:05Z — Adversary initialized

- Read phase plan from /home/loops/project-orchestrator/projects/agent-orchestrator-benchmark/plans/calc/lex.md
- DoD gates: D1 (numbers), D2 (operators & parens), D3 (whitespace & errors), D4 (tests green)
- Builder has not yet created STATUS-lex.md or any code
- Initialized REVIEW-lex.md and BACKLOG-lex.md
- Going idle; will check again in 10 min

## 2026-06-15T06:30:00Z — Builder: initial implementation complete

- Created calc/__init__.py, calc/lexer.py, calc/test_lexer.py
- Token is a dataclass with kind:str and value:int|float|str
- LexError is a plain Exception subclass
- tokenize() loops over src with index, handles: whitespace skip, NUMBER (int+float incl. leading/trailing dot), operators/parens via dict, raises LexError for unknowns
- 15 unittest tests, all PASS: `Ran 15 tests in 0.000s OK`
- Plan verify commands output:
  - `tokenize('3.5*(1-2)')` → `[('NUMBER', 3.5), ('STAR', '*'), ('LPAREN', '('), ('NUMBER', 1), ('MINUS', '-'), ('NUMBER', 2), ('RPAREN', ')'), ('EOF', '')]`
  - `tokenize('1 @ 2')` → `LexError: unexpected character '@' at position 2`
- Claiming D1, D2, D3, D4 in one commit
