+## ADL-043 — Extended HGX diagnostic plan-B is opt-in from the live collect form
+
+**Date:** 2026-04-13
+**Context:** Some Supermicro HGX Redfish targets expose slow or hanging component-chassis inventory
+collections during critical plan-B, especially under `Chassis/HGX_*` for `Assembly`,
+`Accelerators`, `Drives`, `NetworkAdapters`, and `PCIeDevices`. Default collection should not
+block operators on deep diagnostic retries that are useful mainly for troubleshooting.
+**Decision:** Keep the normal snapshot/replay path unchanged, but gate those heavy HGX
+component-chassis critical plan-B retries behind the existing live-collect `debug_payloads` flag,
+presented in the UI as "Сбор расширенных данных для диагностики".
+**Consequences:**
+- Default live collection skips those heavy diagnostic plan-B retries and reaches replay faster.
+- Operators can explicitly opt into the slower diagnostic path when they need deeper collection.
+- The same user-facing toggle continues to enable extra debug payload capture for troubleshooting.
