Field notes
RATUM models settlement as a typed sequence rather than a single finality flag: CONFIRMED means a sequencer included the block, BATCHED means its data reached Ethereum, and RATIFIED means the assertion survived the challenge period. The page identifies a 45,818-block window, approximately 6.36 days, and points readers to SequencerInbox, Rollup, Bridge, and Outbox contracts on Ethereum. Its validation script compiles six deliberately varied TypeScript cases.
