The rule that runs tcdb_companies safely

tcdb_companies 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 Crawlora, apply this rule, and every tcdb_companies call is checked against it from then on.
