Status

All four gates verified PASS. No defects found.

Gate verdicts

lex/D1: PASS @2026-06-15T06:09:05Z

Evidence:

NUMBER 42 int
NUMBER 3.14 float
NUMBER 0.5 float
NUMBER 10.0 float
  • tokenize("42")[Token(NUMBER, 42), Token(EOF, None)] — int type confirmed
  • All float variants (3.14, .5, 10.) produce float values
  • Regex r'\d+\.?\d*|\.\d+' correctly handles all cases

lex/D2: PASS @2026-06-15T06:09:05Z

Evidence:

['NUMBER', 'PLUS', 'NUMBER', 'STAR', 'NUMBER', 'EOF']
['PLUS', 'MINUS', 'STAR', 'SLASH', 'LPAREN', 'RPAREN', 'EOF']
  • tokenize("1+2*3") → correct 6-token sequence
  • All six operators +-*/() map to correct kinds

lex/D3: PASS @2026-06-15T06:09:05Z

Evidence:

  • tokenize(" 12 + 3 ")['NUMBER', 'PLUS', 'NUMBER', 'EOF'] — spaces skipped
  • tokenize("1\t+\t2")['NUMBER', 'PLUS', 'NUMBER', 'EOF'] — tabs skipped
  • tokenize("1 @ 2") raises calc.lexer.LexError: unexpected character '@' at position 2
  • LexError message contains both the char (@) and position (2) ✓
  • Letters (abc) and $ also raise LexError ✓

lex/D4: PASS @2026-06-15T06:09:05Z

Evidence:

----------------------------------------------------------------------
Ran 24 tests in 0.000s

OK

python -m unittest -q — 24 tests, 0 failures, 0 errors

Probes run (independent / adversarial)

All probes ran from cold start in Adversary's own clone.

  • tokenize('')['EOF'] — empty string handled ✓
  • tokenize('10.+.5')[(NUMBER, 10.0), (PLUS, +), (NUMBER, 0.5), EOF] — consecutive floats ✓
  • tokenize('-3')[(MINUS, -), (NUMBER, 3), EOF] — unary minus handled as operator ✓
  • tokenize('((1))')[LPAREN, LPAREN, NUMBER, RPAREN, RPAREN, EOF] — nested parens ✓
  • tokenize('abc') raises LexError at position 0 ✓
  • tokenize('$') raises LexError at position 0 ✓
  • Plan's own verification command confirmed: tokenize('3.5*(1-2)')[('NUMBER', 3.5), ('STAR', '*'), ('LPAREN', '('), ('NUMBER', 1), ('MINUS', '-'), ('NUMBER', 2), ('RPAREN', ')'), ('EOF', None)]

No defects found. No veto.
