The auditor asks what your AI did six months ago. Can you prove it?
The bad day
What people are asking“Can you prove that the logs you are showing today are the same records the system wrote six months ago?”

It's audit season. You now run several AI agents: one drafts customer replies, one moves tickets, one touches internal records. The auditor picks a date six months back and a sensitive action: an agent changed an account setting. Who authorised it? What did the agent rely on? Why did it act?
You have logs. Plenty of them. But they record what was said to the model, not why the agent did what it did. They live in the same systems the agents write to. And the auditor's real question is the hard one: are these the same records the system wrote at the time, or could they have been changed since? An ordinary log can't answer that about itself.
With LogicMem
Each agent writes its actions and what it relied on to one tamper-evident chain of records. Six months later you find the action, see the steps that led to it, and run a check that shows whether any record has changed since it was written.
If everything matches, you show that. If something was altered, the check shows where. Either way you're answering with evidence, not reassurance.
- Several agents, possibly from different vendors, act on real systems
- Someone will one day ask "why did it do that?"
- You need to show your records weren't quietly edited
How it works, briefly
- As your agent works, it writes each action and what it relied on to LogicMem, through the Python SDK or an MCP connection.
- Each record is linked to the one before it with a digital fingerprint (a SHA-256 hash), forming a chain.
- Records are kept on the LogicMem server. Later you ask it to re-check the chain. If a record was changed after it was written, the check fails at that record, and every record after it shows as untrustworthy.
- Corrections are logged as new records, not quiet overwrites, so the original stays visible.
LogicMem tells you whether the record changed. It does not judge whether the decision was right, and it is not a compliance certification. That part stays with your team and your reviewers.
