The rule that runs get_correlations safely

get_correlations is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Crypto Intelligence, apply this rule, and every get_correlations call is checked against it from then on.
