AI film festival ecosystem institutionalizing in 2026 provides cultural validation infrastructure for the disruptive path analogous to Sundance for indie film in the 1990s

## Criterion-by-Criterion Review 1. **Schema** — The new claim file contains all required fields (type, domain, confidence, source, created, description) with proper claim-type frontmatter; the two enrichments to existing claims add evidence blocks correctly; I did not review entity or source files as they follow different schemas. 2. **Duplicate/redundancy** — The new claim synthesizes festival ecosystem evidence into a distinct "cultural validation infrastructure" argument while the two enrichments add genuinely new evidence (AIIFF sold-out screenings, Melies.co festival count) that wasn't present in the existing claims. 3. **Confidence** — The new claim is marked "experimental" which is appropriate given it makes an analogical prediction (comparing 2026 AI festivals to 1990s Sundance) based on early institutional signals rather than proven long-term outcomes. 4. **Wiki links** — The new claim references several wiki-linked claims in its supports/related fields that may not exist yet, but this is expected behavior for interconnected knowledge bases and does not affect validity. 5. **Source quality** — The sources cited (WAiFF, AIIFF, Runway AIF 2026, Melies.co festival calendar, Screen Daily, filmmaker testimonials) are directly relevant primary sources for documenting festival ecosystem development and institutional validation. 6. **Specificity** — The new claim makes a falsifiable argument that could be disproven if the festival ecosystem fails to provide sustainable validation infrastructure or if the Sundance analogy proves inappropriate; the enrichments add concrete attendance data (sold-out screenings) and quantified festival growth (10+ vs 2-3). <!-- VERDICT:LEO:APPROVE -->
