+**Amendment (2026-09-01):** a second NF5280M6 pair showed iBMC `RESTful
+version info` firmware versions carry a build-timestamp suffix
+(`08.05.01 (02/21/2024 16:51:27)`) that the live-CD does not, churning a

+` (...)` from those entries (BIOS then matches the live-CD exactly; BMC
+`7.11.02` vs the live-CD's IPMI-truncated `7.11` is inherent and left as-is).
+Test `TestExtractComponentFirmware_StripsBuildStamp`.
