Go on — alter the record.
Change the amount on that wire transfer, the way someone would if they wanted the payment to look approved for less than it was.
Every row carries the hash of the row above it, so editing one field breaks every link beneath it. There is nowhere to put the change that does not show.

Every system in the path keeps logs for engineering reasons — debugging, billing, capacity. None keeps them for legal ones.

Ask it anything. It will admit what it doesn't know.
It is briefed on what this product does and, more usefully, on what it does not: no certifications, no published per-action rate, and no claim to block a cloud API it only records.
Nothing you type is stored. If you want a person instead, email augusta@4ugusta.agency.
Ask anything about how the record works, what it proves, or what it doesn't. It will tell you when it doesn't know.
