Decision Journal

Every call and every desk decision, time-stamped and chained, nobody edits it afterwards.

The Decision Journal screen of the application, 46 chained entries with their hashes and the verified head hash

Nobody edits it.

Each entry carries the SHA-256 of the one before, so no line can change.

The entries of the Decision Journal with the hash column, each line sealed with the hash of the previous one

The page the bank asks for.

Export the period as a PDF, decision by decision, with the outcomes once they are known.
