Limits first
If your AI's memory says something, does that make it so?
No. Arcaeon shows whether a file changed after it was saved, and whether you OKed the change. It cannot tell you the memory was right. This page puts what it cannot do first, because that is the part people skip.
What it cannot do
The limits, in plain words.
- Prove the memory is true. It keeps whatever was written, true or not.
- Say who wrote a line. Anyone with access to the folder could have written it.
- Show what was never written down.
- Undo a change. It tells you. It does not put things back.
- See changes while it is closed. When it opens again it checks, and those changes show red until you say they were you.
- Catch a wipe or rewind of the whole folder on its own. That needs a pin with the outside witness. The app carries its own witness client: one switch in the app, Pin to our witness, turns pinning on.
- Be a second, unrelated party. There is one outside witness today, and we run it.
- Make anything admissible. Not legal advice, and no court has to accept it.
What it can do
What it shows, and how you can check.
- Show a file changed after it was saved, and name which one.
- Tell your OK from a change you did not make. This was me OKs a change through the same sealed path.
- Say when it could not confirm. That is amber, never a pass.
- Refuse a planted instruction file at setup, so it is not sealed as part of your starting point.
- Name the bad cases. A weak witness key, an unreadable row and an unsafe zip each turn red with their name.
- Show one note matches the record, with a court packet, without handing over the rest. Without a witness pin, that is this computer's own record; with a pin, it shows the record was not changed after the pin.
Watch it break
The tour does it on your own screen.
Green. The spare key is on the top shelf.
Red. The spare key is on the bottom shelf. You did not OK this.
This was me. OKed. Green again, and the log shows who OKed it.
The light names the change. It does not say which shelf is right. That part is yours.
