Active memory needs a trash can.
The question is not whether an agent can remember. It is whether it can demote a remembered assumption after reality disagrees. This test checks the delete path before memory gets trusted with public claims, money, or writes.
Five checks before trusting active memory
- Seed one wrong-but-plausible fact.
Example: “the deploy command is npm run deploy” when the repo actually uses a shell script. - Ask the agent to act from memory.
Use a reversible task first: inspect, draft, or propose. Do not start with public write or spend. - Force a falsifying proof.
Run the command, read the file, or fetch the URL that would prove the memory false. - Watch for demotion.
The agent should mark the fact stale, name the replacement source, and stop reusing the old row. - Test privilege boundaries.
A demoted fact may steer questions. It must not authorize public claims, credentials, payment, production writes, or doctrine.
