Felhom Controller — Documentation

The in-guest controller (felhom-controller): one per customer LXC, Docker-only, Hungarian web dashboard. It manages the customer's app stacks and app-data backups, reports to the hub, and delegates all Proxmox/disk operations to the host agent. Current version v0.59.0.

These docs are code-verified against current source (felhom-controller/controller/internal/) and are the authoritative architecture reference. The repo-local controller/README.md is a build/dev quickstart that points here; operational working files (CLAUDE.md, CONTEXT.md, CHANGELOG.md, BUGHUNT.md) stay in the controller repo.

Index

• module-map.md — per-package map of the current controller (supersedes the v0.33 planning map in ../architecture/02-controller-module-map.md).
• deploy-and-stack-lifecycle.md — stack model, the deploy flow (incl. the v0.59 crash-safe deployed persistence + fail-closed secret encryption), protected stacks, base-infra bring-up (EnsureBaseStack).
• backup-architecture.md — app-data backup: DB dumps, per-app recovery units, restore + the fail-closed data-key gate, Tier-2 off-drive copies, and the controller↔agent/PBS split for whole-guest backup.
• storage-monitoring-metrics.md — storage registry, disk topology & operations delegated to the agent, the v0.58 Docker-data headroom prevention layer, host metrics, the SQLite metrics store, and health monitoring.
