BOTH Tier 0 boxes went offline mid-session (remote site, 12:28 CEST; four routes tried, our
tailscale pod healthy). Q1/Q2/Q3 each keep a part needing a nested VM: those are BLOCKED, not
answered. DooPlex was NOT used as a fallback — Tier 2, and this task did not authorise it.
Established without them:
- STRUCTURAL: ordering='before-network' maps to proxmox-first-boot-network-pre.service
(Before=network-pre.target, Type=oneshot) — it completes before ANY interface is configured,
so a rotation there has a zero-length window BY CONSTRUCTION, not by being fast.
- R-148: the stub does not need 'fully-up'. stub-first-boot.sh has no pvesh/pct/pveum/qm call
(grep rc=1); that usage is in felhom-bootstrap.sh under its own After=network-online unit.
answer.toml.tmpl:27 justifies the current ordering with a dependency that does not exist.
- R-149: the ordering enum has THREE values (before-network, network-online, fully-up), not two.
- MECHANISM (container, not PVE): locked root closes sulogin — 'the root account is locked' for
both '*' and '!', with a working control. So 'discard' and 'lock' are the SAME outcome for
recovery, making the escrow decision binary.
- R-150: all four proxmox-first-boot-* units are Condition-guarded; a failed condition is a SKIP,
so a hook that never ran looks identical to one that succeeded.
- R-151: demo-felhom was installed from an UNCOMMITTED profile — a Tier 0 reference box is not
reproducible from main.
- Q4: four gates in iso-repack.sh enforce the single-entry menu; default/timeout already settable.
The first mechanism probe was invalid (uid 0 bypassed pam_unix; sulogin had no tty) and a teardown
error (shredding the control plaintext) are both recorded as failures, not massaged.
demo-hp teardown is INCOMPLETE and named as such; the command is recorded, not claimed done.

- R-139 (HIGH): a disk filter matching >1 device does NOT fail safe. Observed in a nested VM —
the installer silently picked one of two matching disks and wiped it; validate-answer accepts
such an answer. The 'filter did not match any devices' guard covers the ZERO-match case only.
- No udev property distinguishes an internal system disk from external media. Measured on
demo-felhom with its 1TB external attached: ID_BUS='ata' for BOTH, lsblk RM=0 for both, and
device-info exposes no removability property. demo-hp's NVMe carries no ID_BUS/ID_TYPE at all.
- R-141 (HIGH): the answer schema makes a root credential mandatory, but root-password-hashed='*'
validates AND installs to completion. [first-boot].ordering accepts 'before-network', the only
ordering that closes the exposure window structurally.
- Q3: prepare-iso leaves grub.cfg byte-identical to stock (15 entries, automated AND interactive)
— a two-entry menu is purely a Felhom grub.cfg.tmpl change.
- R-129 resolved: demo-hp's key is the operator's own, added post-install; demo-felhom's IS baked
by an uncommitted profile.
The reachable-before-rotation measurement FAILED twice and is recorded as failed, not inferred.
Opens R-139..R-147; restates R-128.
