Add a whole portfolio at once.
Paste page urls and contract addresses together, one per line. The list is checked and priced before anything is signed, so a typo costs nothing.
Pages
Each is captured exactly as a single notarisation is: every validator reads the page itself and checks each claim against its own copy. That work cannot share a transaction, so each page is one transaction and one signature, worked through in order.
Contracts
A snapshot records what another intelligent contract's views return now, up to 8 of them. Up to 10 contracts fit in one transaction, because a cross contract read is part of deterministic execution rather than something validators have to agree about.
A snapshot is computed, not agreed
Every validator reads the same views and computes the same lines, with no model and no screenshot involved, so a snapshot carries no image check. Its claims are the views in the order they were named, each written as name = value.
Then watch them
Everything added here becomes an ordinary certificate. Capture the same thing again and the two link together, the difference shows, and the network can judge whether it was material. A contract that quietly changes its fee reads like a page that quietly changes its terms.
