## Content conventions that aid extraction
- Every guide, question, list and comparison page opens with a TL;DR answer block
  marked `data-answer="true"` inside schema.org/Answer microdata.
- Statistics-heavy pages carry per-fact source attribution and a sources footer.
- Every page emits JSON-LD (Article, FAQPage, Dataset or SoftwareApplication) with the
  publisher referencing the canonical organization @id above.
- Sitemap and `dateModified` dates reflect the latest site-wide review date.

## Trust and limitations
- Validation scores are model assessments, not probabilities of startup success.
- No outcome study has been published; the ~89% figure is an internal, uncertified match rate.
- Every public claim is labelled Verified, Internal or Illustrative: https://ideaproof.io/evidence
- Score distribution of real stored reports: https://ideaproof.io/research/validation-benchmarks
- Scoring rubric and known gaps: https://ideaproof.io/research-methodology
