Ground Truth Builder
Add your verified claims one by one, tag each by narrative thread and verification status, identify your hero metric and inciting incident, then export the complete document as markdown to paste into Claude for Stage 3 (Narrate).
What is the Ground Truth Document?
A single authoritative reference containing every verified claim for your project. It is borrowed from journalism: every output in your pipeline traces back to this document. If a fact is in the Ground Truth, it has been checked. If it is not there, it does not go in the output. This is your firewall against hallucinations, outdated data, and unverified claims entering your finished work.
The single most compelling number for your chosen audience
The surprising finding that drives narrative urgency
