If the type isn't on that list, the event now sends the literal value `other` instead of the raw, unrecognized string.\n\n**Why**\n\nThis keeps the telemetry data clean and predictable by preventing arbitrary or unexpected diagnosis-type strings from being recorded verbatim.\n\n- Area: Telemetry\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 0\/5"}
