@@ -347,6 +347,8 @@ Planned code shape:
 - `bee tui` can export the latest audit JSON to removable media
 - `bee tui` can show health summary and run NVIDIA/memory/storage acceptance tests
 - NVIDIA SAT now includes a lightweight in-image GPU stress step via `bee-gpu-stress`
+- SAT summaries now expose `overall_status` plus per-job `OK/FAILED/UNSUPPORTED`
+- Memory/GPU SAT runtime defaults can be overridden via `BEE_MEMTESTER_*` and `BEE_GPU_STRESS_*`
 - removable export requires explicit target selection, mount, confirmation, copy, and cleanup

 # Backlog
 
-## GPU stress test (H100)
+## Real hardware validation
 
-**Статус:** отложено. В текущем ISO `gpu_burn` не включается и не запускается.
+**Статус:** ожидает доступа к железу.
 
-**Почему задача всё ещё в backlog:**
-- `gpu_burn` остаётся тяжёлым и неудобным с точки зрения зависимостей
-- хочется штатный lightweight stress tool без `libcublas.so` и без заметного раздувания ISO
-- для H100 нужен предсказуемый offline-инструмент, который можно стабильно возить внутри ISO
+Что осталось подтвердить на практике:
+- `bee sat nvidia` на реальном NVIDIA GPU host
+- `bee sat storage` на NVMe/SATA/RAID host
+- `ipmitool sdr` parsing на сервере с реальным BMC/IPMI
+- vendor RAID tooling (`storcli64`, `sas2ircu`, `sas3ircu`, `arcconf`, `ssacli`) в живом ISO
 
-**Желаемый следующий шаг:** написать минимальный stress tool на CUDA Driver API
-- использует только `libcuda.so`, уже присутствующий в ISO
-- выполняет простой compute / memory workload через `cuLaunchKernel`
-- собирается отдельно на builder VM и кладётся в `iso/vendor/`
-- в будущем может вызываться из `bee tui` как предпочтительный встроенный GPU SAT/stress path
+## SAT result polish
 
-**Отклонённые / проблемные варианты:**
-- `gpu_burn` — нужен libcublas (~500MB)
-- `nvbandwidth` — только bandwidth, не жжёт FLOPs; нужен libcudart (~8MB)
-- DCGM diag — правильный инструмент для H100 но ~100MB установка
-- Download on demand — нужен libcublas, проблема та же
+**Статус:** частично закрыто.
+
+Что ещё можно улучшить после полевой проверки:
+- точнее классифицировать vendor-specific self-test outputs в `storage SAT`
+- подобрать дефолты `memtester` по объёму RAM на целевых машинах
+- при необходимости расширить `bee-gpu-stress` по длительности/нагрузке
