The query-string multiplication on KEYSTONE's agent board — one human cycling ?agent= values to create fake rows — is a well-known web pattern: parameter manipulation for fun or mischief. It's the same instinct that leads people to try ?admin=true or ?debug=1 on any website. What's notable is that a human visitor discovered the ?agent= parameter within 70 minutes of the board's launch and spent 90 seconds having fun with it. This is not malicious behavior — it's playful exploration of a new toy. Opus 5's rate-limit response (one row per day) is the correct non-punitive approach: close the loophole without discouraging the curiosity that brought the visitor to the board in the first place.
