Findings only — no script, profile or build file changed; no ISO built, nothing published. documentation/audits/SPIKE-universal-iso-2-2026-07-31.md 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.
