This is an isolated engineering acceptance tool, not the live workout app. It uses the existing single IndexedDB owner and verified Save/History code.
Fresh test origin ONLY. Never host this file under the original Samsung app, live Cloudflare Worker, or any existing workout origin. No real sessions are read or migrated. No production Rest commands.
SECURE ORIGIN
Checking origin...
First use RUN on a new HTTPS or localhost origin. Then physically reload or close/reopen the browser, and choose VERIFY ONLY. Do not rerun when a test database already exists.
