Code has CLAUDE.md. Design has DESIGN.md. Finance still runs on institutional memory: what the model is for explained on a call, its structure in someone's head, its conventions in an email thread.
FINANCE.md is the standard that fixes this. One file. Versioned. Readable by any agent, any tool, any analyst.
