Journey fit
Tariff and duty math belongs in validate when you are proving unit economics and pricing before you commit to inventory or supplier terms. Pricing subphase is where solo builders model COGS, margins, and retail price under real trade rules—not after the storefront is built.
How it compares
Live duty calculator MCP integration, not a general web scraping skill or accounting ledger.
