admin 1a68b53b06 hub v0.82.0 (R-120): the vouch path REFUSES a golden the fleet has already outrun
The golden's version IS the controller it bakes (build-golden.sh:345 defaults
GOLDEN_VERSION to the controller tag), so a golden behind the newest deployed
controller means every FRESH install lands on stale application code. On the R-120
occurrence that stale code shipped a customer-facing falsehood: a box from the
0.185.1 golden told a customer whose backup drive had fallen out that the backup was
on the same disk as the system -- false, the drive was gone -- and offered a
different drive as the remedy.

WHY A GATE, NOT A REMINDER. The gap has opened three times: R-111 (golden's agent 17
releases behind), R-115 (agent built and deployed, never published), R-120 (this).
The first two were closed by re-baking and remembering; remembering then failed
again. R-29 is the standing proof that a check nobody runs is worse than none because
it reads as coverage -- hostinstall_gates.py sat RED and uninvoked across three
version bumps and hub_confirm_gate.py has never run at all. So the property that
matters is not whether a check exists but whether it BLOCKS.

- Wired into handleSetArtifacts (internal/web/configs.go), immediately before the
  only write, on the sole UI path to SetArtifactManifest -- it runs on every vouch
  without anyone choosing to. A script in scripts/ would have been a fourth orphan.
- It REFUSES (operator ruling, 2026-07-30), with a flash naming the remedy.
- Signal: store.NewestReportedControllerVersion() over reports.controller_version,
  SEMVER-compared in Go -- MAX() in SQL ranks 0.99.0 above 0.186.0, a pair this
  fleet has shipped. No outbound call, no new credential.
- Fail-open in exactly two deliberate cases: an empty golden field (clearing the
  manifest is legitimate) and an unknown fleet version (a new hub must vouch its
  first golden).

NEAR-MISS RECORDED: the first draft read guests.controller_version, a column that
exists in the schema and that NOTHING writes -- it would always have seen "" and
failed open, i.e. inert, this gate's own failure shape. Caught by grepping for a
writer before trusting the column.

Blind spot stated rather than papered over: a controller no box has ever run is
invisible to this signal. Not the failure that has bitten -- all three instances were
deployed-newer-than-baked.

4 tests through the PRODUCTION handler over httptest, never an injected seam. The
refusal asserts both the flash and that the manifest was NOT written, because a gate
that redirects and saves anyway reads as enforcement while providing none. Red-proof:
deleting the block makes the stale golden vouchable and both assertions fail.

ROADMAP R-29's audit list now records this as the FIRST enforced gate, so the
contrast with its three orphans is kept rather than lost. The orphans are unchanged.

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.
