 Produces `HardwareIngestRequest` JSON compatible with core/reanimator.
 
 **Principle:** OS-level collection — reads hardware directly, not through BMC.
-Fully unattended — no user interaction required at any stage. Boot → update → audit → output → done.
-All errors are logged, never presented interactively. Every failure path has a silent fallback.
+Automatic boot audit plus operator console. Boot runs audit immediately, but local/SSH operators can rerun checks through the TUI and CLI.
+Errors are logged and should not block boot on partial collector failures.
 Fills the gaps where logpile/Redfish is blind: NVMe, DIMM serials, GPU serials, physical disks behind RAID, full SMART, NIC firmware.
