CHAOS NIGHT round 6: what a whole-system backup costs the household
Measured while the vzdump was in flight (started 21:55:24Z, 2.1GB and growing):
- containers running: 4 of 26. The whole-guest backup stops twenty-two apps.
- front doors: LAN 301 (traefik is one of the four still up) but public 404 -
  nothing behind the proxy to serve. Every app unavailable for the duration.
- alarms: NONE. Twenty-two apps went down at once and not one alarm fired.

Those two findings point opposite ways and both matter. The downtime is real
and total, not a brief pause - this is the standing whole-system-backup downtime
row, seen on a fresh box with twelve apps. And the suppression is correct: the
backup's own stack stops belong to a suppression set, so the box does not alarm
about downtime it caused deliberately.

The duration itself is taken from the round's runner when it reports, not
estimated from a single sample.

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.

Sections

Controller (in-guest) — controller/

The Docker-only app-domain controller. Full per-area docs grounded in current source (v0.59.0). → controller/README.md: module map, deploy & stack lifecycle, backup architecture, storage/monitoring/metrics, auth/hub/sync/integrations.

Where we stand — architecture/where-felhom-stands.*

The operator's one-page picture of what is proven, built, partial and missing.

Host agent & platform — architecture/, proxmox-platform.md

The operator-tier agent and the Proxmox platform.

Hub (operator backend) — architecture/05

Security audits & remediation — audits/

Spike & test findings — tests/

Per-slice spike/validation findings (phases 0–5, slices 7–10). See tests/.

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.
