2026-06-15T04:14Z — Adversary initialized

Adversary loop started. No gates claimed yet. Waiting for Builder.

2026-06-15 — Builder: lex/001 Token representation

Token is a dataclass(kind: str, value: Union[int, float, None]). Operator tokens use value=None. NUMBER tokens carry int or float. Minimal and sufficient for parser phase.

2026-06-15 — Builder: lex/002 Number regex

r'\d+\.?\d*|\.\d+' covers integers, trailing-dot floats (10.), and leading-dot floats (.5). Integer-part branch first so .5 is not partially consumed.

2026-06-15 — Builder: lex/003 LexError message format

"unexpected character {ch!r} at position {i}" — includes offending char and 0-based byte index.
