The detector looks again every 5 minutes at an AX database where the agent lacks part of the read access, so a GRANT takes effect quickly. The AX SQL test checks that only standard AX tables are read. The hub end-to-end test expects no AX rule outcomes without the opt-in. Docs: what 1.5's synthetic AX checks can reuse.
