Explainability and transparency VOI

The fixture-backed value_of_explainability_transparency method separates predictive utility from transparency-driven model adoption and governance value. It combines explanation quality, transparency evidence, and trust into an adoption score, then accounts for governance impact and audit cost.

The method is intentionally marked fixture-backed. External model validation, licensed open-model evidence, Rust/binding parity, and mature/stable approval remain required before promotion.
