Fogbreak does real tasks for you — reschedule an inspection, review a trade, intake a patient, release a grant — but every action is checked against a permission, and every action is written into a tamper-proof receipt chain. Below are four real runs of the actual engine, and the actual receipts they produced. You can try to tamper with one and watch the chain catch it.
Every governed action above is one link here. Each receipt's fingerprint is built from the one before it, so changing any single receipt breaks every link after it. Click any receipt (or use “Tamper”) to try — the chain re-checks itself live, exactly the way the engine does.
