cproudlock 0b1625ed87 Build/playbook re-run safety: corp access, netplan rollback, first-boot retry ...

H1  corp_admin_cidrs (UFW 22/9009 on the corp NIC from these only; refuses
    when it would lock out the current SSH client) and corp_ssh_password_auth
    (sshd drop-in, passwords only from the imaging subnet). Defaults keep the
    current behaviour and print a loud warning.
H2  pxe-netplan-apply.sh: pre-flight refusal (pxe-MAC NIC holds the default
    route, a DHCP lease or the route to an SSH client), run from the USB
    before anything changes; post-apply checks (names, imaging IPv4, corp
    IPv4 back within 30 s, SSH route) and a 120 s systemd-run auto-revert.
H3  restore() puts the previous NIC names back (two-phase rename via
    temporary names, so swaps work) before generate + apply.
H4  a failed rename is fatal (restore + exit 1); the play drops the old
    any-interface UFW rules only after verifying both NICs and their
    per-interface SSH rules.
H5  first-boot checks the playbook exit code, retries at next boot (max 5),
    writes /var/lib/pxe-firstboot.failed and /etc/issue + /etc/motd banners.
M1  build-usb.sh verifies iPXE files against the playbook pins, every wheel
    against its own package's hashes, drops the unpinned pip fallback,
    requires --site-vars or --no-site-vars.
M2  webapp restarts when the code, wheels or unit changed.
M3  ignore-carrier on the imaging NIC; ip_nonlocal_bind kept for the
    apache/networkd boot race.
M4  menu suffix must match blancco_kver; missing kernel with no earlier
    build is fatal; a live menu with the staged Blancco test entry is not
    overwritten.
M5  build-proxmox-iso.sh is unsupported (hard exit); use build-usb --image.
M6  deploy-unattend.sh: password via SSHPASS env and sudo stdin only,
    %q-quoted remote args, sha256 check of the live file; lint-unattend.py
    reads PXE_SERVER/PXE_USER/PXE_PASS and uses sshpass -e.
M7  the playbook lints the unattend files before the force: yes copies
    (lint-unattend.py ships on CIDATA as scripts/); pre-commit ACMR.
M8  Blancco initramfs build: no ignore_errors, pipefail, trap cleanup.
Also: Send-ImagingStage.ps1 deploy, carrier hook install tasks
(pxe-nic-carrier, networkd-dispatcher), L1 imaging-active hold
(allow_disruptive) and no iPXE downgrade below an Updates-page install,
L2 iso-volid, L3 kver pin read from the playbook, L4 cp -rL, L5 refuse
>= 4 GiB WinPE files, L6 PIP_DIR wipe guard, L7 per-package wheel hashes,
no online fallback, L8 check-updates.py (apt_pkg/cached compare, all
components, exit 2 on no debs / bad answers).
