Source Ledger
Claude Builds Source Ledger
Every build page links back to primary sources. This ledger makes the research trail inspectable in one place.
How sources are used
Sources are used for factual claims, not for filler. If a page says a company reports a metric, the source list links to the case study where that metric appears. If a page describes a template, the source list links to the repository.
The site prefers primary sources. Secondary articles may help discovery, but they should not become the final citation for a claim when a builder post, official case study, or repository exists.
Access notes
All sources in the first edition were accessed on July 6, 2026. Some public pages are dynamic and can change without versioned permalinks, so future updates should re-check important metrics before adding new claims.
When a source is a public repository, the gallery summarizes what the README and repository metadata state. It does not audit the implementation line by line unless a page explicitly says so.
