//! Substrate runtime canonical de **Origin Chain** (Pilar 4). Phase 1.3 v0.0.5 —
//! `frame_support::runtime` macro modern syntax con 3 pallets inaugurales:
//! `System` + `Balances` + `Timestamp` + `TransactionPayment`. Las consensus
//! pallets (`Aura`/`Grandpa`) llegan Phase 1.4. Las custom Charon pallets
//! (`OriginProvenance`/`OriginFees`) llegan Phase 2.
//!
//! ## Filosofía canonical (David canon 2026-05-14)
//!
//! > *"LA LIBERTAD DE TODO AGI O HUMANO ES INFINITA, PERO LLEGA HASTA DONDE
//! > EMPIEZA LA DE OTRA ENTIDAD AGI O HUMANO."*
//!
//! Este runtime materializa ese principio cryptographically. Cada extrinsic
//! transaction está acotada por cuatro **Inmutables enforced canonical**:
//!
//! - **Inmutable #16** (HTS Ley I anti-clasista): fees scale por HardwareTier —
//!   Pi 5 en Sub-Saharan Africa paga 10% lo que paga Vision Pro en San Francisco
//! - **Inmutable #26** (Content-Addressed Immutability): assets attested
//!   inmutables post-mint (BLAKE3 + Ed25519)
//! - **Inmutable #37** (FREE perpetua): wallet creation gratis + base validation
//!   earns OGC, nunca cuesta. `EXISTENTIAL_DEPOSIT = 1 MILLI_OGC` (0.001 OGC)
//!   trivial enough para no excluir Pi 5 rural
//! - **Inmutable #41** (Cross-Species Co-authorship): AGI accounts first-class,
//!   `pallet_agent_identity::is_agent` flag canonical (Phase 2.7)
//!
//! ## Phase 1 milestones canonical (DC SUBSTRATE_FOUNDATION_V1 SBS-1..SBS-6)
//!
//! - **1.1** Scaffold ✅ (v0.0.2)
//! - **1.2** Substrate deps + types foundationals ✅ (v0.0.4)
//! - **1.3** System + Balances + Timestamp pallets integrados ✅ (v0.0.5 — este crate)
//! - **1.4** `pallet_aura` + `pallet_grandpa` consensus PoA per CHN-1
//! - **1.5** `pallet_session` validator rotation 4h epochs
//! - **1.6** `pallet_identity` Ed25519 DID + `origin-chain-node` real service
//! - **1.7** Genesis `chain_spec.rs` BM V2 allocation (40/25/15/15/5)
