Verification, availability, reviews and evidence (44 pts) are this expert's standing on every query. Topic relevance (36), semantic fit (6) and location (6) are scored per query; language (8) depends on the query's requirement.
Every expert carries a reviewer-assigned trust level from L0 (self-declared) to L6 (board certified), based on verified evidence — publications, credentials, affiliations. Levels are never self-assigned, and the platform blocks any grant whose minimum evidence isn't on file. How verification works
