Supervised clean-slate reinstall of the demo N100 from a pipeline-built Felhom ISO + onboarding rehearsal. Core objectives GREEN: first-boot chain reached rc-0 on the first attempt on real hardware (closes slice A's operator-gated boundary), serial-filter safety proven on metal, PBS-DR reconciler self-healed on the reused peer, DMI verdict -> key on MAC+UUID. Hard obstacle was firmware not the pipeline: this cheap AMI AN3PLUS 0.01 board won't UEFI-boot the ISO's GRUB from USB (relocation 0x0; SB-off + shim-bypass don't help), worked around live with a grub-mkimage loader from the box's own GRUB (slice-B input). 7 findings logged (F1 firmware loader HIGH; F2/F3/F4 reused-customer edges -> R-1/Peti; F5 guest-RAM, F6 drive-init mount, F7 back-route). Full doc in documentation/tests/; ROADMAP R-21 + REPORT + CONTEXT updated. No production code changed.
