DECISIONS — shared (append-only)

2026-06-15 — Token representation

Used a dataclass with kind: str and value (Any). This lets NUMBER store int or float, and other tokens store the character string. Simple and sufficient for the parser phase.

2026-06-15 — Number parsing

Integers → int, floats (containing .) → float. Handles .5, 10., 3.14.

2026-06-15 — Advisory: multi-dot number strings

tokenize("1.2.3") produces a bare ValueError from float() rather than a LexError because the greedy digit+dot scanner consumes the whole string before conversion. DoD only requires LexError for character-level invalids, so this is not a phase-lex defect. Parser phase should guard against malformed numeric literals if needed.
