S3 appendix CGNAT smoke test run live on felhom-pve (agent v0.64.0) with a USB-tethered phone. Tunnel established + held its NAT mapping across a 32-min idle soak on PersistentKeepalive=25 alone (0 stalls, final ping no-bounce). - §7: open-validation CLOSED; two honest caveats kept (SIM had a public mobile IPv4 so true CGNAT 100.64/10 not reproduced — retest-when-able; + MTU). - §4.3: mobile outer path MTU ~1400 black-holed bulk data at the shipped 1420; MTU 1340 restored the PBS page. OPEN DECISION: permanent vs per-connection. - §4.4: keepalive 32-min mobile-NAT hold datapoint. - §4.2: dual-stack v6 trap (wg-quick prefers endpoint AAAA, rides un-NATed v6). - §8: S6 row CGNAT closure marked done. - REPORT.md: overwritten with this operational-validation summary. Runbook: RUNBOOK-s3-cgnat-smoke. Docs-only; no agent/hub/controller code.

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

architecture, storage/monitoring/metrics, auth/hub/sync/integrations.
Host agent & platform — architecture/, proxmox-platform.md

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.
