gates / gates (push) Successful in 12s
R-267 CLOSED (26.2s -> 0.24s warm); R-268 filed: I printed a live token into a transcript
R-267 closed by hub v0.101.0. Measured after the 60s memo: cold 13.4s, warm 0.24-0.33s. The operator
sees a quarter-second except at most once a minute.

R-268 filed against myself. Setting up R-221's live drill, a one-liner meant to list bootstrap.json's
KEYS printed the local_api object whole, including its token, for guest 9201. Reported rather than
quietly rotated, because a secret reaching a transcript is a finding whatever its blast radius.

Exposure assessed rather than assumed, and it is small: the token opens only the agent's per-guest
local API on the island bridge between that host and that one guest, self-scoped to guest 9201, not
routable from the LAN or internet, on a Tier-0 disposable box with no customer data. Using it already
requires code execution there, at which point an attacker has more than the token.

Rotation exists (TokenStore.Mint, last-write-wins per VMID) but must also rewrite the guest's
bootstrap.json or the controller loses agent access — an operator-timed act, not a background one.
The general fix is upstream: reading secret-bearing JSON should go through a helper that prints keys
and never values, the discipline the golden bake already uses for the Gitea token.

R-221 also recorded as PROVEN ON HARDWARE in STATUS.

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.
