The CGNAT smoke test's OPEN DECISION is made: fleet-wide, permanent, family-agnostic client MTU 1280 (RFC 8200 IPv6-minimum floor), implemented in felhom-agent v0.65.0. - §4.3: OPEN DECISION → made decision + rationale + rejected alternatives (auto-probe/per-type = fragility for a non-metric; MSS-clamp = unneeded). "ships MTU 1420" → 1280; corrected "fixed-line unaffected" (DS-Lite ~1452, PPPoE would also black-hole at 1420 — one floor covers all). - §4.2: 1280 is family-agnostic so MTU correctness is decoupled from v4/v6 resolution; v4-pin noted as a separate optional determinism item. - §3.2 wire-field note + §8 S6 row: MTU 1420 → 1280; S6 residual now only the true-CGNAT-SIM retest. - REPORT.md overwritten. Docs-only; the constant change is in felhom-agent v0.65.0. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PSK5g6qYLknKj8u3QAFEr6
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.

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.
