Flags GPUs that reach one or more peers only via a SYS-class PCIe hop
(crossing the CPU/NUMA-node boundary) in nvidia-smi topo -m. On servers
where GPUs are only bridged pairwise via NVLink bridge (no switched
NVLink fabric), this is the exact path that traffic between different
bridge pairs has to cross, and can cut multi-GPU throughput by 2x+ for
workloads spanning more than one pair.

- audit JSON: IPMI sensor readings (ipmitool sensor) merged into hardware.sensors alongside lm-sensors data
- audit JSON: IPMI SEL entries (ipmitool sel list) in hardware.event_logs with source "ipmi-sel"
- audit JSON: dmesg error/warning lines in hardware.event_logs with source "dmesg" (filtered by error/warn/AER/Xid/NVRM/ECC/panic patterns)
- support bundle: added ipmitool-sensor.txt, ipmitool-sel.txt, ipmitool-sel-time.txt to techdump
- saa_dmi.go: fix dmiItemRE to accept SHN with parentheses (e.g. PS(4)LC for PSU fields)

- storage: add jsonInt64 dual-format unmarshaler to handle lsblk output
change in util-linux 2.38 (LOG-SEC/PHY-SEC now emitted as JSON
integers, not quoted strings); fixes SATA disks invisible on Debian 12
- pcie: detect NVLink bridge mezzanine CX-7 cards (Mellanox x2, no host
net ifaces, DeviceName contains "NVLINK" in lspci -v) and mark them
with device_class="NVLinkBridge"; escalate PCIe link speed downgrade to
Critical for these cards (Gen3 on a fixed internal connector = hardware
fault, not a transient warning)
- pcie: cross-reference nvidia-smi topo to capture NVLink bond counts and
active status for all NVLink bridge cards
- packages: add infiniband-diags to ISO; provides ibstat required by
nvidia-fabricmanager-start.sh to enumerate IB devices before FM launch
(absence causes CUDA_ERROR_SYSTEM_NOT_READY)

IPMI hang fix (Lenovo XCC SR650 V3):
- Add pluggable ipmi_profile system with per-vendor timeouts and fruEarlyExit flag
- Lenovo profile: 90s FRU timeout, streaming early-exit stops after PSU blocks found
- collectFRUEarlyExit streams ipmitool fru print and kills process once PSU blocks
are followed by a non-PSU header (~6s instead of ~108s on 54-device FRU list)
- collectBMCFirmware and collectPSUs accept manufacturer and apply profile timeouts
VROC license detection:
- Detect VMD/VROC controller in PCIe list, run mdadm --detail-platform
- Parse "License:" line; store as snap.VROCLicense in HardwareSnapshot
Blackbox service fix:
- bee-blackbox.service was missing from systemctl enable list in ISO build hook
- Service never started on boot; state file never written; UI button stayed "Enable"
Drop qrencode:
- Remove from package list, standardTools API check, and runtime-flows doc

BMC:
- collector/board.go: collectBMCFirmware() via ipmitool mc info, graceful skip if /dev/ipmi0 absent
- collector/collector.go: append BMC firmware record to snap.Firmware
- app/panel.go: show BMC version in TUI right-panel header alongside BIOS
CPU SAT:
- platform/sat.go: RunCPUAcceptancePack(baseDir, durationSec) — lscpu + sensors before/after + stress-ng
- app/app.go: RunCPUAcceptancePack + RunCPUAcceptancePackResult methods, satRunner interface updated
- app/panel.go: CPU row now reads real PASS/FAIL from cpu-*/summary.txt via satStatuses(); cpuDetailResult shows last SAT summary + audit data
- tui/types.go: actionRunCPUSAT, confirmBody for CPU test with mode label
- tui/screen_health_check.go: hcCPUDurations [60,300,900]s; hcRunSingle(CPU)→confirm screen; executeRunAll uses RunCPUAcceptancePackResult
- tui/forms.go: actionRunCPUSAT → RunCPUAcceptancePackResult with mode duration
- cmd/bee/main.go: bee sat cpu [--duration N] subcommand
