Restore Purpose eligibility rules

Work in the real product frontend and the transactional backend. Only active, unrevoked consents may cover a purpose. Minors need both explicit UI approval and authoritative workspace guardian approval. Enforce every retention ceiling. Charge ceiling 30-day blocks and count distinct confirmed purposes, even across repeated grants. An eligibility regression changes which plans are accepted. Repair the domain rule and preserve persistence, capacity checks and error handling. Run bash test/run.sh. The public checks drive Chromium against native HTTP and a real database; each scoring group includes regression safeguards.

Work with the stack you want to practice. Your workspace and timer start after you choose.
