base/plugins/bootnode/bootnode.go

// Package bootnode is the Go port of the Python bootnode backend
// (bootnode/api/), built natively on Hanzo Base as a plugin.
//
// It consolidates the blockchain developer platform — multi-network OAuth,
// project API keys, team management, and 1-click network/node/key
// provisioning — onto Base's IAM + base infrastructure. Identity is owned by
// Hanzo IAM (reused via github.com/hanzoai/base/iam); per-org and per-user data
// isolation come from the platform plugin's PrincipalIsolation="sqlite" mode;
// billing is wired through the commerce plugin's Client interface.
//
// Network/NodeFleet/KMSSecret provisioning targets bootno.de/v1 custom
// resources applied via a dependency-free Kubernetes REST client
// (plugins/bootnode/kube) — no client-go, no CGO.
//
// This is a foundation: 5 of 20 API modules are ported end-to-end (auth, team,
// networks, nodes, keys). The remaining modules are tracked in the PR body.
