R-193: a guest rebuild silently drops the offsite tier; R-192 cause established
Operator confirms no hub-side offsite config change, so the regression was not an
action. Evidence: demo-hp's controller went 0.187.0 -> 0.192.0 at 06:12:18 with a
new config hash and the agent re-keyed its leaf three minutes earlier — a guest
rebuild. The last pre-rebuild report shows the tier fully healthy: escrowed, last
success 02:16:39Z, 15 snapshots, 40.9 MB. No offsite object in the 108 reports
since.

Mechanism: the restic credential is delivered once. demo-hp consumed its secret on
2026-07-23; the rebuilt controller has no copy and no way to request another.
demo-felhom survived the SAME rebuild only because its secret was still unconsumed
— it consumed it four seconds after its config hash changed and was reporting
offsite again 76 seconds later. That difference was luck, not design.

Also sharpens R-192: the self-heal's guard refuses when any report since the
consume carried an offbox target, but that query reads the OLDEST 500 reports —
all of which predate the rebuild. Healthy history before a rebuild is not evidence
the credential still works, which is why the automation that exists for this case
declined to act.

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.

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 05, slices 710). 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.
