world.treeline.route.review

An athlete's rating and review of a route. Field-compatible with app.attrails.review (subject, rating, text, completedAt, images, langs, labels, createdAt), plus an optional link to the athlete's own activity on the route and the gear they used. AppViews treat the most recent review per (author, subject) as canonical: to change a review, write a new one; older ones stay in the repo as history.
