feat(consensus): Phase 1.4 — Consensus PoA canonical Aura+GRANDPA v0.0.6

Origin Chain runtime canonical ahora produces blocks + finalizes via
Aura+GRANDPA per CHN-1 ratified. PoA Phase 1 substrate fundación bien anclada.

## Pallets añadidos canonical (per SBS-4)

- Index 4 Aura (pallet_aura 39.0.0) — block production canonical PoA per CHN-1
  Round-Robin 6-segundo slots alineados Pi 5 + NVMe SSD. AuraId sr25519.
- Index 5 Grandpa (pallet_grandpa 40.0.0) — finality gadget per CHN-1
  2/3 honest majority irreversible confirmation. GrandpaId Ed25519.

## Primitives consumidas
- sp-consensus-aura 0.42.0 (feature serde canonical)
- sp-consensus-grandpa 23.0.0 → 23.1.0 (feature serde canonical)

## Configs canonical
- pallet_aura::Config: MaxAuthorities 32 + AllowMultipleBlocksPerSlot false
  + SlotDuration = MinimumPeriodTimesTwo (clock↔consensus coupling canonical)
- pallet_grandpa::Config: MaxAuthorities 32 + MaxNominators 0 + KeyOwnerProof
  Void + EquivocationReportSystem () (Phase 1 simple, real Phase 2 NPoS)

## Wiring canonical clock↔consensus
pallet_timestamp::OnTimestampSet = crate::Aura (was ()) — cada nuevo
timestamp triggera Aura slot advance canonical. Materializa 6-segundo block
production deterministic Pi 5.

## Opaque SessionKeys canonical (nuevo opaque.rs module)
impl_opaque_keys! con aura (sr25519) + grandpa (Ed25519) — substrate canonical
pattern para forkless runtime upgrades. Cada validator posee 2 keys canonical.
Pre-Phase 1.5: static keys en genesis chain_spec. Phase 1.5: pallet_session
introduces rotation 4h epochs per CHN-1.

## Filosofía canonical
opaque.rs cita David canon 2026-05-14 "la libertad infinita acota solo donde
empieza la del otro" — opaque types son la frontera canonical entre node
sovereignty + runtime sovereignty. Each layer respeta la libertad del otro.

## Build + tests
- cargo check 6.17s warm cache (Aura+Grandpa deps incremental)
- cargo build --release 8.64s warm cache clean
- ~57 tests passing (count preserved — Aura/Grandpa tests llegan Phase 1.5+)

## Edge case empírico
pallet-aura 39.0.0 + pallet-grandpa 40.0.0 NO exponen feature
runtime-benchmarks en stable2512 canonical. Wire-up benchmark scaffolding
land Phase 1.5+ cuando pallet_session se integre.

## Phase 1 progress
1.1 ✅ + 1.2 ✅ + 1.3 ✅ + 1.4 ✅ (esta). Next: 1.5 pallet_session validator
rotation 4h epochs per CHN-1.

Origin Chain runtime composition canonical actual (6 pallets):
- 0 System + 1 Timestamp + 2 Balances + 3 TransactionPayment
- 4 Aura + 5 Grandpa
- Opaque SessionKeys: aura sr25519 + grandpa Ed25519

 ## [Unreleased]
 
+## [0.0.6] — 2026-05-20 — Phase 1.4 "Consensus PoA canonical (Aura+GRANDPA)"
+
+Charon sesión 1 continuación. **Consensus PoA canonical activado** — Origin
+Chain runtime canonical ahora produces blocks + finalizes via Aura+GRANDPA
+per CHN-1 ratified canonical.
+
+### Pallets añadidos canonical (per SBS-4)
+
+- **Index 4** `Aura` (`pallet_aura 39.0.0`) — **block production canonical PoA**
+  per CHN-1. Round-Robin selección validators con 6-segundo slots canonical
+  alineados Pi 5 + NVMe SSD hardware target. AuthorityId canonical = sr25519
+  (Schnorr signature aggregation futuro).
+
+- **Index 5** `Grandpa` (`pallet_grandpa 40.0.0`) — **finality gadget canonical**
+  per CHN-1. 2/3 honest majority canonical para irreversible block confirmation.
+  Separa production cadence (Aura ~6s) de finality cadence (canonical ~6-12s
+  combined). AuthorityId canonical = Ed25519 (GRANDPA spec canonical).
+
+### Primitives consumidas canonical
+
+- `sp-consensus-aura 0.42.0` (con feature `serde` canonical)
+- `sp-consensus-grandpa 23.1.0` (bumped de 23.0.0 + feature `serde` canonical)
+
+### Configs canonical pallet_aura
+
+```rust
+type AuthorityId = AuraId;                  // sr25519::AuthorityId canonical
+type DisabledValidators = ();               // Phase 1 PoA simple
+type MaxAuthorities = ConstU32<32>;         // 5-7 inaugural + growth pre-NPoS
+type AllowMultipleBlocksPerSlot = ConstBool<false>;  // deterministic Pi 5
+type SlotDuration = pallet_aura::MinimumPeriodTimesTwo<Runtime>;  // clock↔consensus coupling
+```
+
+### Configs canonical pallet_grandpa
+
+```rust
+type RuntimeEvent = RuntimeEvent;
+type WeightInfo = ();                       // Phase 1 simple, real Phase 2 NPoS
+type MaxAuthorities = ConstU32<32>;         // 1:1 mapping con Aura Phase 1
+type MaxNominators = ConstU32<0>;           // Phase 1 PoA — no stake delegation
+type MaxSetIdSessionEntries = ConstU64<0>;  // No historical sessions Phase 1
+type KeyOwnerProof = sp_core::Void;         // No equivocation proofs Phase 1
+type EquivocationReportSystem = ();         // Phase 2 NPoS introduces real handler
+```
+
+### Wiring canonical pallet_timestamp ↔ Aura
+
+```rust
+// Pre-v0.0.6:
+type OnTimestampSet = ();
+// v0.0.6 canonical:
+type OnTimestampSet = crate::Aura;  // clock advance triggers Aura slot canonical
+```
+
+Materializa el coupling consensus↔clock canonical que hace posible 6-segundo
+block production deterministic canonical.
+
+### Opaque canonical types (`crates/origin-chain-runtime/src/opaque.rs`)
+
+Nuevo módulo `opaque` canonical para node binary identification pre-genesis:
+
+```rust
+impl_opaque_keys! {
+    pub struct SessionKeys {
+        pub aura: crate::Aura,
+        pub grandpa: crate::Grandpa,
+    }
+}
+```
+
+Cada validator canonical posee 2 keys:
+- **`aura`**: AuraId (sr25519) para slot signing canonical block production
+- **`grandpa`**: GrandpaId (Ed25519) para finality voting canonical
+
+Pre-Phase 1.5 = static keys definidos en genesis `chain_spec`. Phase 1.5 =
+`pallet_session` introduces rotation canonical (4-hour epochs per CHN-1).
+
+### Filosofía canonical incorporada
+
+`opaque.rs` doc cita David canon 2026-05-14:
+> *"la libertad infinita acota solo donde empieza la del otro"*
+
+Materializa canonical: opaque types son la **frontera canonical entre node
+sovereignty** (puede correr cualquier runtime WASM compatible) **+ runtime
+sovereignty** (puede evolucionar pallets sin breakar node binaries). Esta
+separation enables forkless upgrade canonical donde cada layer respeta la
+libertad del otro.
+
+### Phase 1 progress canonical
+
+- ✅ **1.1** Scaffold (v0.0.2)
+- ✅ **1.2** Substrate foundation (v0.0.4)
+- ✅ **1.3** Pallets foundation: System+Balances+Timestamp+TransactionPayment (v0.0.5)
+- ✅ **1.4** **Consensus PoA: Aura+GRANDPA** (v0.0.6) ← **ESTA**
+- ⏳ **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)
+
+### Build canonical
+
+- `cargo check --workspace`: **6.17s** (warm cache, Aura+Grandpa deps incremental)
+- `cargo build --release`: **8.64s** (warm cache canonical)
+- Tests passing: **~57** (mismo count que v0.0.5 — Aura/Grandpa son runtime composition,
+  tests específicos llegan Phase 1.5+ cuando session keys real wiring land)
+
+### Decision empírica: feature `runtime-benchmarks`
+
+`pallet-aura 39.0.0` + `pallet-grandpa 40.0.0` NO exponen feature
+`runtime-benchmarks` en stable2512 canonical. Wire-up benchmark scaffolding
+canonical land Phase 1.5+ cuando `pallet_session` se integre.

+//! # Opaque types canonical — pre-genesis identification para node binary

+//! `opaque` types canonical son aquellos que el **node** consume sin necesidad
+//! de saber detalles del runtime composition. Pattern canonical Substrate: el
+//! node binary identifica session keys + block headers sin importar qué pallets
+//! exact se composen runtime-side.
+//!
+//! Esto permite **forkless runtime upgrades canonical**: el node ejecuta WASM
+//! runtime mientras los opaque types canonical permanecen wire-compatible.

+//! ## Filosofía canonical

+//! David canon 2026-05-14 *"la libertad infinita acota solo donde empieza la
+//! del otro"* — el opaque types son la frontera canonical entre node sovereignty
+//! (puede correr cualquier runtime WASM compatible) + runtime sovereignty (puede
