Installation
Heroic is an Electron app distributed as an RPM on GitHub releases. The tasks: downloads and installs it via dnf install -y /tmp/heroic.rpm (auto-resolves deps). Version pinned to v2.20.1.
COPR repos exist (atim/heroic-games-launcher) but builds are currently failing — GitHub RPM is more reliable.

Game Stores
Heroic manages three game stores:
- Epic Games Store (via Legendary backend)
- GOG (via gogdl backend)
- Amazon Prime Gaming (via Nile backend)
Wine/Proton Management
Heroic manages its own Wine/Proton independently from Steam:
- Downloads Wine-GE, Proton-GE, Wine-Lutris, etc. to
~/.config/heroic/tools/ - Also supports UMU (Universal Proton runner)
- Does NOT depend on Steam's Proton installations
Data Directories
| Path | Content |
|------|---------|
| ~/.config/heroic/ | Config, game settings, Wine/Proton tools |
| ~/Games/Heroic/ | Game installs + Wine prefixes |
Both are persistent named volumes.

Use when authoring or modifying a charly PLUGIN — a candy with a `plugin:` block that contributes Providers (verbs/kinds/deploy-targets/steps/builders/commands), its own CUE schema, builtin (compiled-in) or external (out-of-tree git repo). Covers the unified Provider model, the per-plugin CUE-schema contract (single source → Go params for dev + schema-over-Describe RPC for runtime), the SDK, and the loader.

tools
VerifiedTrustedCommunity
The CUE data-validation / configuration CLI (cue), pinned to v0.16.1. Use when working with the cue candy, installing the cue binary into a box or onto a target:local dev host, or running the offline schema-vendoring pipeline that feeds charly's egress validation.

overthinkos/egress
tools
VerifiedTrustedCommunity
CUE EGRESS validation — validating (and, where it adds value, generating) the config files charly WRITES to a system BEFORE the bytes hit disk. MUST be invoked before working on charly/egress.go, the vendored schemas under candy/plugin-egress/egress-schemas/vendor/, the ValidateEgress / registerVendoredEgressKind path, the offline `task cue:vendor` pipeline, or adding an egress schema for any written artifact (cloud-init, k8s manifests, traefik routes, runtime config, install ledger, systemd/quadlet units, ssh_config, libvirt XML).

Kubernetes cluster-probe declarative check verb — the `kube:` check verb (nodes, pods, ingress, storage class, addon health, apply/delete, and arbitrary resource GETs) served out-of-process by the candy/plugin-kube plugin (vendored client-go; no external kubectl required).
