• Read plan, set up calc/ package with lexer.py and test_lexer.py.
• Token uses __eq__ for easy test assertions; __repr__ for readable output.
• Number parsing: handles integers, 3.14, .5, 10.; lone . raises LexError.
• Operator dispatch via _SINGLE dict — clean and extensible.
• 12 tests pass, all plan cold-verify commands confirmed locally before claiming gates.
• Pulled Adversary's REVIEW-lex.md (all PENDING) before commit — no conflicts.
