admin 2d64ee7241 Campaign 10: OPEN observation — backup_target_* pair went silent under rapid cycling
Three I1/I1-pair violations in ~5 minutes, all "expected event absent". Recorded as
an OPEN observation, NOT a finding: the system was mid-abuse when it was seen, and
a verdict taken on a system being hammered is worth little.

Established: it is not hub-side suppression and not a truncated log. The hub pod
has 0 restarts over 43h and the controller's own log matches it line for line, so
the events were never emitted. It is specific to the backup_target_* pair - the
generic storage_disconnected/reconnected pair for the other drive kept firing
normally throughout the same window.

Also sampled, and the more serious half if it survives quiescence: mentes reads
bound_under_parent=False while the backup-target state simultaneously reports
degraded=false. Those cannot both be right - a false healthy on the backup target
is I5/I6's failure mode.

NOT established: whether the pair recovers once cycling stops (the harness detaches
every ~2 min; a customer does not), whether the 02:25:37 controller restart is
implicated, and whether the degraded=false sample was transient.

Disposition written into the doc: after the run ends, quiesce with both drives
attached, then do ONE slow detach/reattach and see whether the pair fires. That
distinguishes "does not survive rapid cycling" from "the target alarm has silently
stopped working", which would be severe.

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.
