Agent Skills: financial-data-sourcing

Maps every input a company analysis needs to where it comes from — filing line items, market data, Damodaran reference datasets, macro series — with units, update frequency, acceptable fallbacks and the consistency rules that bind them. Use when gathering data for a valuation, when an input is missing and a substitute is needed, when deciding whether a user-supplied figure can be accepted at face value, or when checking that figures are internally consistent.
