Both Tier 0 boxes went offline mid-session (provider cable fault; four routes tried, no Tier 2
fallback used) and returned. All three scenarios then ran to completion on real PVE, each signalled
by reboot-mode='power-off' rather than a disk hash.
- A LOCKED ROOT CLOSES THE PVE WEB INTERFACE. Measured at the exact endpoint the UI uses
(POST /api2/json/access/ticket, root@pam) WITH A WORKING CONTROL: known-password install returns
HTTP 200 + ticket; locked install returns 401 for every password and none can exist.
passwd -S root = L, shadow = literal-asterisk, PVE uses the stock PAM stack.
- GRUB recovery mode is also closed ('the root account is locked') — but init=/bin/bash still gives
an unauthenticated root@(none):/#. A locked box is recoverable, operator-only, at the console.
The installed GRUB has NO password, so locking root is not a physical-security measure. R-152.
- before-network MEASURED (A/B, same image): the hook RUNS (marker, uptime 6.58s) with entropy 256,
writable /etc, all binaries and openssl_rand_len=32, while ip_global is EMPTY and
listen_22_8006 = 0. fully-up is the converse: sshd+pveproxy active, 3 listening. Zero window.
- R-148: answer.toml.tmpl:27 justifies fully-up with a pvesh/pct dependency the stub does not have
(grep rc=1) — it blocked the ordering now measured as the fix.
- R-149 three ordering values; R-150 Condition-guarded hooks skip silently; R-151 demo-felhom built
from an uncommitted profile.
Three probes failed and are recorded as failed: a container probe that ran as uid 0, a GRUB probe
that missed the 1-second menu timeout, and a kernel-line edit one line off (caught by a pre-typing
verification screendump). The interim 'Layer 1 teardown INCOMPLETE' is corrected — the fixture had
never landed, because the staging mkdir was in the SSH call that timed out.
Felhom — Documentation
Felhom is a managed home-server service for Hungarian households, built on a three-component model over Proxmox:
- Hub — operator backend on k3s (
hub.felhom.eu). Repo:felhom.eu/hub/. - Host agent — one per Proxmox host; operator-tier; owns all Proxmox interaction. Repo:
felhom-agent/. - In-guest controller — one per customer LXC; Docker-only; manages the customer's apps. Repo:
felhom-controller/.
This directory is the central, code-verified documentation home for all three components plus the platform and the security-audit record.

Conventions
- Code-verified, not memory-derived. Architectural claims here are checked against the actual current source; if a claim can't be verified it is omitted and flagged, not guessed.
- Per-repo operational working files (
CLAUDE.md,CONTEXT.md,CHANGELOG.md,BUGHUNT.md,REPORT.md,TASK.md) live in their own repos — they are operational, not published docs. - Authoritative versions at last refresh: controller v0.59.0, agent v0.29.1, hub v0.11.0.
