admin f3975cf5bc E-2d executed on a fresh box: C1/C2 proven, C3/C4 partial, C5 FAILS — R-112/113/114
Full ISO/PAIRING route on a nested PVE VM on demo-hp, after R-111 was fixed
earlier in the session. Bind -> running controller in 3m35s. The install fetched
the artifacts published an hour before and restored the golden baked 20 minutes
before, so the publish train is proven end to end on a real install.

C1 PROVEN: "felhom-host-install v1.22.0", "Day-0 provision SUCCESS", guest 9201
running, bootstrap unit wrote its done-flag and self-disabled. This retires E-2's
"installer-logic-tested, not install-tested".

C2 PROVEN: both DEGRADED warning lines verbatim, backup.local_backup_target=local,
no felhom-backup storage created, and the install did not abort.

C3/C4 PARTIAL and C5 FAILED — three findings, none fixed:

R-112 (P1): E-2's degraded banner and offer have NO UI CONSUMER. The endpoint
returns byte-exact copy; grep 'backup-target' across every html/js/css is 0 hits
and no page handler injects the state. Templates fetch 18 distinct /api/storage/*
endpoints; these two are the only ones with zero references. v0.185.1 fixed the
router mount and stopped one layer short of the render. Fifth instance of
seam-built-but-never-wired.

R-113 (P1): the drive-absent gate CANNOT FIRE on device loss. planDriveGates
reads presence from BoundUnderParent = "is this path in the guest's mountinfo".
The raw mount is a device-bound systemd unit and dies with the device; the
agent's own bind is not device-bound and outlives it, so the gate sees "present"
forever. Live: agent reported the drive absent every 20s for 4.5 minutes, the
controller logged 0 [gate] lines, the hub received zero events -- neither
backup_target_absent nor the generic storage_disconnected. Sixth instance of the
class: E-2b wired the seam to a condition that cannot occur.

R-114: on target-drive loss the message claims the backup is on the system disk
(false) and offers the drive that just vanished. Invisible only because of R-112,
so it must be fixed BEFORE R-112 is wired.

Also filed as a second instance under R-110 rather than a new ID: host-install
fetches nine files from raw/branch/main and the hub vouches a sha for one;
E-2a's wrapper is installed 0755 to /usr/local/sbin, root-fenced in sudoers,
validated only by bash -n.

C4 is fully proven at API level: decline path (registration confers no role),
restart_required:true, agent did NOT self-restart (in-flight check performed and
recorded first), E-2a wrapper created the storage at the drive's own mountpoint,
and healthy renders nothing.

Teardown: VM destroyed, scratch storage removed, pvesm status after == before
(local-lvm 38.77%), guest 9201 and drill-r50 untouched. Hub records for e2d-fresh
remain -- delete correctly refused at four gates, finally "host is ONLINE";
deletable once it ages to DOWN. Command recorded in OPEN-ITEMS.md.

capability-map NOT touched: the customer-facing legs are broken rather than
proven, and the map has no E-2 rows at all.

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.
