AkurAI-VPN / crates/akurai-control/src/main.rs

Latest change 1b6130c5a11fd67aea78991820e14225c714dafc - feat: add AkurAI IDP OIDC login, session management, and VPN endpoint CRUD (v0.0.3) by Claude Code

//! `akurai-control` — the AkurAI VPN control plane.
//!
//! Owns device enrollment, overlay IP allocation, the peer map, ACL policy,
//! audit, heartbeat state, and relay assignment for the network hosted at
//! `vpn.olibuijr.com`. This is a 0.0.1 skeleton: the modules below name each
//! responsibility and the HTTP listener seam, but none of the control-plane
//! logic is implemented yet. Argument parsing is hand-rolled to keep the
//! zero-dependency promise.
