Methodology
Every tool on AI Biz Hub ships with a methodology page — what it assumes, what data it pulls from, and what it cannot tell you. Hero methodologies get the full treatment; the rest run through a structured template so the eight sections appear in the same order everywhere.
Citation hierarchy
Primary academic → government data → verifiable branded reports. No vendor-blog sources.
Freshness
Pricing and benchmark snapshots carry an as-of date. Stale entries are re-sourced, not quietly carried forward.
Change log
Append-only. Every weight change, benchmark re-source, or correction is dated.
