Attacks that exploit this kind of access
The rule that runs approve_proposal safely

approve_proposal stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Metis Public Health, apply this rule, and every approve_proposal call is checked against it from then on.
