Nothing atm, but you never know what you may find. I would assume that most whistleblowers didn’t know they joined a shady organisation until years down the line…

Maybe, add a clause what should happen if you disappear for more than x days. For most jurisdictions you are considered dead if you disappear for a few years.

Why not keep a copy?

Also, both people are single point of failures. Maybe, 5-6 people where each has an encrypted payload and the keys to decrypt everyone else’s payload.

Another thing to consider is that you won’t know immediately that the information you stumbles upon is incriminating. Sometimes it may take years until you have all the pieces of the puzzle.
