//! # origin-chain-consensus
//!
//! Aura (Authority Round) block production + GRANDPA finality, PoA Phase 1 →
//! NPoS Phase 2 per **CHN-1** canonical. Stub crate in v0.0.1; full Substrate
//! integration lands in Phase 1 (Sesiones 4-8) of [Charon roadmap].
//!
//! [Charon roadmap]: https://git.originmetaverse.com/Origin_Metaverse/arkhe-origin-chain
//!
//! ## Phase 1 milestones
//!
//! - 1.2 `pallet_aura` + `pallet_grandpa` integration
//! - 1.4 `pallet_session` (validator rotation, epoch 4h)
//! - 1.6 `origin-chain-node` binary (dev mode, single validator)
//!
//! ## Phase 2 transition criteria (NPoS, all must hold)
//!
//! - TVL > $500K USD equivalent in OGC staked
//! - ≥20 independent validator candidates with certified hardware
//! - MAU > 10,000
//! - PoA uptime > 99.5% for 6 months
//! - External security audit passed by ≥1 recognized firm
