admin 955083c0fc Campaign 9: the Tier-2 restore paths are PROVEN; 3 defects filed, none fixed
Phase A is the headline and it passed on live hardware, through the real endpoints the UI
posts to: a customer who deletes files — or their entire app data directory — gets everything
back byte-identical, and the app works afterwards (paperless served the restored bytes over
its own API at the exact pre-deletion sha256). A1's two non-destruction promises both hold.

Three defects, recorded not fixed:
  C9-F1 (HIGH)   the Tier-2 restore button is offered for apps it can never restore, takes a
                 real outage, and reports "nothing was missing" — indistinguishable from a
                 genuine result, while 156 MB of that app's data sits unread in the same copy.
  C9-F2 (HIGH)   an app in a crash loop never alarms on any channel; StateRestarting is in no
                 down-set, so F-OBS's own heartbeat printed "0 currently down" for 9 minutes.
  C9-F3 (MEDIUM) an interrupted offsite run leaves a lock the self-heal cannot reach; the tier
                 is dead until a human unlocks and the operator is told "unknown reason".
                 This answers Phase C item 8.

Two candidates were deliberately NOT filed: a recovery-unit poisoning the catalog sync healed
in ~3 min, and a snapshot_id that is documented as logging-only. Reporting either would have
been reporting an artifact.

Stopped at the end of Phase B (plus D10), then full recovery — both boxes healthy, real
cadences, offsite tier proven working again, no leaked scratch guests, peti untouched.
D11's approved staleAfter compression turned out not to be a knob; reported, not worked around.

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.
