An hourly labeling-services rate ($8-$10 per hour, attributed to the Boost Workforce add-on) was read from labelbox.com/pricing/ by the proposing pass and could not be re-found on review: labelbox.com/pricing/ and labelbox.com/pricing/calculator/ both returned HTTP 404 on 2026-09-05 (the site was restructured; only /products/{recursion,horizon,terra,alignerr}/ remain in its sitemap). No hourly figure is recorded until a live page states one.
