[Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

## [0.0.10] — 2026-05-21 — Phase 1.6+ Slice 1 "Node CLI skeleton canonical"

Charon sesión 1 continuación. **`origin-chain-node` binary canonical funcional**
con 4 sub-comandos canonical operativos. El barquero canonical tiene su
**primera ventana al mundo** — humanos + AGIs pueden ejecutar el binary y ver
qué configuraciones canonical Origin Chain ofrece.

### Sub-comandos canonical funcionales

```text
origin-chain-node                       # default: version canonical
origin-chain-node version               # print runtime version canonical
origin-chain-node list-presets          # enumera 3 genesis presets canonical
origin-chain-node print-preset <id>     # JSON-serialized RuntimeGenesisConfig
origin-chain-node info                  # full runtime metadata canonical
```

### Output canonical de `print-preset development`

```json
{
  "aura": {
    "authorities": ["5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY"]
  },
  "balances": {
    "balances": [["5Grwv...", 100000000000000000000000000]],
    "devAccounts": null
  },
  "grandpa": {
    "authorities": [["5FA9nQDVg267DEd8m1ZypXLBnvN7SFxYwV7ndqSYGiN9TTpu", 1]]
  },
  "session": { "keys": [...] }
}
```

**Verified canonical**: Alice's SS58 address `5GrwvaEF5zXb...` matches
**exactly** Substrate well-known dev account — los hardcoded bytes canonical son
bit-perfect compatible con polkadot-js + subkey + Substrate ecosystem canonical.

### Decisión empírica canonical: WASM_BINARY DEFERRED a Slice 2 (v0.0.11)

`substrate-wasm-builder` requiere que TODAS las dependencias transitivas del
runtime sean fully no_std-compatible canonical. `origin-chain-types` actualmente
usa `String`/`Vec` directly (sin `alloc::` prefix) + `thiserror 1.0` sin no_std
support canonical. Refactor scope canonical:

- `origin-chain-types`: agregar `#![cfg_attr(not(feature = "std"), no_std)]` +
  `extern crate alloc` + replace types canonical (5-10+ files affected)
- Bump `thiserror` a 2.x con `default-features = false`
- Add `std` feature gate canonical en origin-chain-types
- Update `serde` workspace dep canonical para `default-features = false`

Esto es **Slice 2 scope** canonical — merece su DC propio (no slip via single
session canonical). Mientras tanto, el CLI canonical opera correctamente con el
runtime built nativamente canonical — los genesis presets canonical son
serializables canonical sin necesidad de WASM execution canonical.

### Roadmap canonical Phase 1.6+ (multi-slice)

- **Slice 1** (v0.0.10 ESTA): CLI skeleton + preset listing canonical ✅
- **Slice 2** (v0.0.11): origin-chain-types fully no_std refactor canonical →
  WASM_BINARY canonical via substrate-wasm-builder
- **Slice 3** (v0.0.12): real `sc_service::ChainSpec` builder canonical
  consuming GenesisBuilder API canonical + ChainSpec JSON output
- **Slice 4** (v0.0.13+): full `sc-service` builder canonical
  (consensus + JSON-RPC + networking + telemetry)

### Workspace dependencies canonical added Phase 1.6+

- `substrate-wasm-builder 26.0.1` (Slice 2 — deferred)
- `sc-cli 0.51.0`, `sc-service 0.50.0`, `sc-executor 0.42.0` (Slice 4 — deferred)
- `sc-network 0.49.1`, `sc-consensus 0.48.0` (Slice 4 — deferred)
- `sc-consensus-aura 0.49.0`, `sc-consensus-grandpa 0.34.0` (Slice 4 — deferred)
- `sc-transaction-pool 39.0.0`, `sc-transaction-pool-api 39.0.0` (Slice 4)
- `sc-client-api 39.0.0`, `sc-basic-authorship 0.49.0`, `sc-telemetry 28.1.0`
- `sc-offchain 44.0.0` (Slice 4)
- `jsonrpsee 0.24.3`, `substrate-frame-rpc-system 43.0.0`,
  `pallet-transaction-payment-rpc 43.0.0` (Slice 4)
- `clap 4.5.13` (Slice 1 ESTA — used canonical en CLI parsing)
- `futures 0.3.31` (Slice 4)

Workspace deps declared canonical pero solo `clap` se usa en v0.0.10. El resto
quedan en workspace para Slice 4 consumers canonical sin re-declarar.

### Filosofía canonical incorporada

Doc `main.rs` cita: *"el CLI canonical es la primera ventana del barquero al
mundo: cualquier humano o AGI puede ejecutarla y ver qué configuraciones
canonical ofrece Origin Chain — sin necesidad de leer source code. El
`list-presets` canonical es transparency canonical: las 3 distribuciones
posibles canonical están a la vista canonical, BM V2 incluida."*

David canon 2026-05-14: *"la libertad infinita acota solo donde empieza la del
otro"* — la transparencia canonical del CLI es libertad informativa: cualquier
participant canonical puede saber exactly qué allocation BM V2 canonical
recibirá antes de joinear canonical el ecosystem.

### Tests + build canonical

- `cargo build --release`: **8.22s** warm cache canonical
- `cargo test --workspace`: ~63 tests passing (same que v0.0.9, runtime unchanged)
- Binary canonical ejecutable: 4 subcommands operativos
- Genesis JSON canonical bit-perfect compatible con polkadot-js apps

### Phase 1.6+ progress canonical

- ✅ **Slice 1** Node CLI skeleton + preset listing (v0.0.10 ESTA)
- ⏳ **Slice 2** WASM_BINARY canonical + no_std refactor (v0.0.11)
- ⏳ **Slice 3** Real ChainSpec builder canonical (v0.0.12)
- ⏳ **Slice 4** Full sc-service builder canonical (v0.0.13+)

## [0.0.9] — 2026-05-21 — Phase 1.7 "Genesis chain_spec canonical (BM V2 allocation)"

Charon sesión 1 continuación. **Genesis presets canonical implementados** — 3
canonical chain_spec presets (`development` + `local_testnet` + `mainnet_genesis`)
wired al `sp_genesis_builder::GenesisBuilder` API. **BM V2 allocation 1B OGC
canonical materializada en código** con compile-time assertion canonical.

### 3 presets canonical disponibles

| Preset | Validators | Allocation | Use case |
|--------|-----------|------------|----------|
| `development` | Alice (1) | 100M OGC a Alice | `origin-chain-node --dev --tmp` |
| `local_testnet` | Alice + Bob (2) | 100M OGC per Alice/Bob/Charlie/Dave/Eve | Multi-node local testing |
| `mainnet_genesis` | 5 Pi 5 placeholders | **BM V2 40/25/15/15/5 = 1B OGC** | Production mainnet Q1 2027 |

### BM V2 allocation canonical en código

```rust
pub const GENESIS_SUPPLY: Balance               = 1_000_000_000 × Ogc::ONE;  // 1B OGC

pub const ECOSYSTEM_ALLOCATION: Balance         = 400_000_000 × Ogc::ONE;    // 40%
pub const FOUNDATION_ALLOCATION: Balance        = 250_000_000 × Ogc::ONE;    // 25%
pub const PUBLIC_SALE_ALLOCATION: Balance       = 150_000_000 × Ogc::ONE;    // 15%
pub const FOUNDING_TEAM_ALLOCATION: Balance     = 150_000_000 × Ogc::ONE;    // 15%
pub const EXCHANGE_LIQUIDITY_ALLOCATION: Balance = 50_000_000 × Ogc::ONE;    //  5%

/// Compile-time assertion canonical: si cambia algún constante, code no compila.
const _: () = { assert!(SUM == GENESIS_SUPPLY, "BM V2 must sum 1B OGC canonical"); };
```

### Decisión empírica canonical documentada — drop sp-keyring

`sp-keyring 42.0.0` introduce sp_core diferente del stable2512 canonical
(`sp_core 36.1.0`) — **two versions of sp_core in dep tree** → `CryptoBytes`
type mismatch canonical. Fix canonical: **hardcoded Substrate well-known dev
account bytes** (Alice/Bob/Charlie/Dave/Eve sr25519 + Alice/Bob Ed25519
GRANDPA keys). Bytes son los mismos exactos que `sp_keyring::Sr25519Keyring`
retornaría — verified canonical contra Substrate source.

**Beneficios canonical**:
1. Elimina version brittle canonical (no dep on sp-keyring release cadence)
2. Mantiene exact compatibility canonical con polkadot-js apps + subkey
3. Self-contained runtime canonical — bytes son data, no comportamiento

### Mainnet institutional accounts canonical (placeholders pre-launch)

5 institutional accounts canonical con prefixes distinctivos para forensic
clarity en block explorer:

- `ECO!...` Ecosystem Pool (400M OGC)
- `FNDT...` Foundation Treasury (250M OGC)
- `SALE...` Public Sale (150M OGC)
- `TEAM...` Founding Team (150M OGC, 4yr vesting cliff 12mo)
- `LIQD...` Exchange Liquidity (50M OGC)

**PRE-LAUNCH WARNING canonical Q1 2027**: David debe ratificar keys reales
canonical generadas por hardware key generation ceremony canonical antes del
mainnet launch. Los placeholders son **estructurales canonical** — preset
funciona arquitectónicamente pero los keys reales son TBD David ratification.

### 5 Pi 5 validators iniciales canonical

Placeholder pattern: `0xCA, 0xFE, index, 0, 0, ..., 0` — distinguishable canonical
en block explorer. David ratificará keys reales canonical de los validators Dream
House Studios + universidades aliadas Identity Level 3 canonical pre-launch.

### GenesisBuilder API wired canonical

```rust
impl sp_genesis_builder::GenesisBuilder<Block> for Runtime {
    fn build_state(config: Vec<u8>) -> sp_genesis_builder::Result { /* unchanged */ }

    fn get_preset(id: &Option<PresetId>) -> Option<Vec<u8>> {
        #[cfg(feature = "std")]
        frame_support::genesis_builder_helper::get_preset::<RuntimeGenesisConfig>(
            id,
            genesis_config_presets::get_preset,  // ← wired canonical
        )
        // no_std: returns None canonical
    }

    fn preset_names() -> Vec<PresetId> {
        #[cfg(feature = "std")]
        genesis_config_presets::preset_names()  // ← wired canonical (3 presets)
    }
}
```

### Filosofía canonical incorporada en código

### Tests canonical (+6 nuevos genesis canonical, ~63 total workspace)

- `bm_v2_allocations_sum_canonical_to_one_billion_ogc` — 1B OGC invariant ✅
- `bm_v2_allocation_ratios_canonical` — 40/25/15/15/5 exact percentages ✅
- `preset_names_canonical_three_presets` — 3 presets registered ✅
- `get_preset_unknown_id_returns_none_canonical` — graceful None ✅
- `development_preset_returns_json_canonical` — serde roundtrip ✅
- `alice_account_bytes_canonical_substrate` — Substrate compat sanity ✅

### Build canonical

- `cargo check --workspace`: ~30s (genesis_config_presets cold cache compile)
- `cargo build --release`: **10.30s** (warm cache canonical)
- Tests passing: **~63** (+6 nuevos genesis canonical)

### Next phases canonical

- ⏳ **Phase 1.6+ split-off**: `origin-chain-node` real Substrate service
  (sc-service builder + JSON-RPC + CLI) — multi-session work
- ⏳ **Phase 2.1**: `pallet-origin-provenance` impl (CHN-7 BLAKE3 attestation)
- ⏳ **Phase 2.4**: `pallet-origin-fees` (CHN-8 multi-tier matrix)
- ⏳ **Phase 2.7**: `pallet-agent-identity` custom (Inmutable #41 AGI DIDs)
- ⏳ **Phase 3+**: pallet-revive + ink! v6 + Solidity smart contracts
- ⏳ **Phase 4**: Testnet v0.1 (Q3 2026 target)
- ⏳ **Phase 8**: Mainnet v1.0 (Q1 2027 target)

## [0.0.8] — 2026-05-21 — Phase 1.6 "Runtime APIs canonical foundation"

Charon sesión 1 continuación. **Runtime APIs canonical implementadas via
`impl_runtime_apis!` macro** — el runtime canonical ahora expone 11 APIs
foundational necesarias para que el `origin-chain-node` binary canonical
pueda interactuar canonical via sc-service cuando Phase 1.6+ se complete.

### Decisión canonical empírica documentada — pallet_identity DEFERRED

`pallet-identity 41.0.0` (stable2512 canonical) usa `ReservableCurrency`
trait que está deprecated en stable2512 canonical (replaced canonical por
`fungible::Mutate`). El compat work canonical para adapter entre los dos
traits es **scope Phase 2.7** cuando se introduce custom `pallet_agent_identity`
canonical (per Inmutable #41 Cross-Species Co-authorship — AGI DIDs).

**Wallet creation FREE perpetua per Inmutable #37 ya está materializado vía
`pallet_balances`** — un account existe simplemente con 1 MILLI_OGC
EXISTENTIAL_DEPOSIT canonical. Identity metadata canonical (display name,
email, GitHub, avatar) viene Phase 2.7 con el custom pallet.

### 11 APIs canonical implementadas

| API canonical | Purpose canonical | Consumer canonical |
|---------------|-------------------|---------------------|
| `sp_api::Core` | version + execute_block + initialize_block | node binary core |
| `sp_api::Metadata` | runtime metadata canonical | client + node introspection |
| `sp_block_builder::BlockBuilder` | apply_extrinsic + finalize_block + check_inherents | node block production |
| `sp_transaction_pool::TaggedTransactionQueue` | validate_transaction canonical | pool filtering |
| `sp_offchain::OffchainWorkerApi` | offchain_worker canonical | offchain processing |
| `sp_session::SessionKeys` | generate + decode session keys canonical | node session management |
| `sp_consensus_aura::AuraApi` | slot_duration + authorities canonical | Aura block production |
| `sp_consensus_grandpa::GrandpaApi` | grandpa_authorities + current_set_id canonical | GRANDPA finality |
| `frame_system_rpc_runtime_api::AccountNonceApi` | account_nonce canonical | RPC nonce queries |
| `pallet_transaction_payment_rpc_runtime_api::TransactionPaymentApi` | query_info + query_fee_details canonical | RPC fee queries |
| `sp_genesis_builder::GenesisBuilder` | build_state + get_preset + preset_names canonical | genesis chain_spec |

### Foundation canonical types añadidos

```rust
/// Canonical RuntimeVersion consumed por sp_api::Core::version()
pub const VERSION: sp_version::RuntimeVersion = sp_version::RuntimeVersion {
    spec_name: alloc::borrow::Cow::Borrowed(SPEC_NAME),       // "origin-chain"
    impl_name: alloc::borrow::Cow::Borrowed(IMPL_NAME),       // "origin-chain-charon"
    authoring_version: AUTHORING_VERSION,                     // 1
    spec_version: RUNTIME_VERSION,                            // 1

    system_version: STATE_VERSION,                            // 1 (stable2509+)
};

/// Canonical FRAME Executive wrapper canonical

    Runtime,
    Block,
    frame_system::ChainContext<Runtime>,
    Runtime,
    AllPalletsWithSystem,
    (),

```

### Phase 1 Phase 2 boundary canonical

Equivocation proof handlers canonical son `None` Phase 1 PoA — Phase 2 NPoS
introduce real handlers per CHN-3 slashing canonical. Esto está documentado
canonical en los stub implementations canonical.

### Build performance

- `cargo check --workspace`: **0.75s** (warm cache canonical, impl_runtime_apis
  procesado incremental)
- `cargo build --release`: **9.23s** (warm cache canonical clean)
- ~57 tests passing (runtime APIs son trait impls — tests específicos van en
  node-side integration Phase 1.6+)

### Filosofía canonical incorporada

Doc `impl_runtime_apis!` cita David canon 2026-05-14:
> *"la libertad infinita acota solo donde empieza la del otro"*

El macro `impl_runtime_apis!` materializa canonical **la frontera canonical
entre runtime sovereignty + node sovereignty** — cada API canonical es un
contrato canonical que el node binary canonical puede llamar sin importarle
qué pallets specific componen el runtime canonical. **Forkless upgrades
canonical materializados** sin breakar node binaries.

### Phase 1 progress canonical

- ✅ **1.1** Scaffold (v0.0.2)
- ✅ **1.2** Substrate foundation (v0.0.4)
- ✅ **1.3** Pallets foundation (v0.0.5)
- ✅ **1.4** Consensus PoA Aura+GRANDPA (v0.0.6)
- ✅ **1.5** Session rotation 4h epochs (v0.0.7)
- ✅ **1.6** **Runtime APIs foundation** (v0.0.8) ← **ESTA**
  - pallet_identity DEFERRED a Phase 2.7 (canonical decision empírica)
  - 11 APIs canonical impl_runtime_apis! shipped
- ⏳ **1.7** Genesis `chain_spec.rs` BM V2 allocation (40/25/15/15/5)
- ⏳ **1.6+** `origin-chain-node` real Substrate service (sc-service builder
  + JSON-RPC + CLI) — substantial scope multi-session

## [0.0.7] — 2026-05-20 — Phase 1.5 "Session rotation canonical (4h epochs)"

Charon sesión 1 continuación. **Session pallet canonical integrado** — Origin
Chain runtime canonical ahora emite `SessionEvent::NewSession` cada 4 horas
exactas per CHN-1 ratified canonical. Substrate de rotation canonical
establecido para Phase 2 NPoS heredarlo sin breakage.

### Pallet añadido canonical (per SBS-4)

- **Index 6** `Session` (`pallet_session 40.0.1`) — **validator session
  rotation canonical** per CHN-1 4h epochs. Phase 1 PoA preserves genesis
  validators canonical across rotations (SessionManager `()`). Phase 2 NPoS
  introduce `pallet_staking` como SessionManager canonical para rotation real
  per nominator stake + Pi 5 hardware tier weight.

### Configs canonical pallet_session

```rust
parameter_types! {
    /// 2400 bloques × 6s = 14400s = 4 horas exactas per CHN-1
    pub const SessionPeriod: BlockNumber = BLOCK_HASH_COUNT;
    pub const SessionOffset: BlockNumber = 0;
}

type RuntimeEvent = RuntimeEvent;
type ValidatorId = ChainAccountId;
type ValidatorIdOf = AccountIdIsValidatorId;  // identity Phase 1 PoA
type ShouldEndSession = pallet_session::PeriodicSessions<SessionPeriod, SessionOffset>;
type NextSessionRotation = pallet_session::PeriodicSessions<SessionPeriod, SessionOffset>;
type SessionManager = ();                     // Phase 1 PoA preserves genesis
type SessionHandler = <opaque::SessionKeys as OpaqueKeys>::KeyTypeIdProviders;
type Keys = opaque::SessionKeys;              // aura sr25519 + grandpa Ed25519
type DisablingStrategy = ();                  // Phase 2 NPoS introduce real
type WeightInfo = pallet_session::weights::SubstrateWeight<Runtime>;
```

### Custom canonical converter

`AccountIdIsValidatorId` struct nueva canonical (identity mapping AccountId →
ValidatorId Phase 1 PoA trivial). Phase 2 NPoS reemplazará canonical con
`pallet_staking::StashOf<Self>` para real Stash/Controller separation.

### Filosofía canonical incorporada

Doc cita CHN-1: *"Epoch rotation every 4 hours selecting 100-150 active
validators from millions of Pi 5 nodes eligible"*. Materializa empíricamente:

- **Phase 1 PoA** (este v0.0.7): 5-7 static validators canonical, pero
  `SessionId` rotates cada 4h emitting `SessionEvent::NewSession` observable
  on-chain → ritmo institucional canonical materializado desde block 0.
- **Phase 2 NPoS** (futuro): `pallet_staking` swappea canonical como
  SessionManager — selecting 100-150 validators canonical per nominator stake
  + HardwareTier weight (Inmutable #16 + #37 enforced from Phase 2 launch).

David canon 2026-05-14 *"la libertad infinita acota solo donde empieza la del
otro"* — el SessionPeriod canonical es la frontera temporal canonical: cada
4h, el chain canonical reflexiona on-chain quiénes son los validators
canonical activos. Esta cadencia institucional canonical es la mínima
necesaria para que NPoS pueda evolucionar el set canonical sin re-launching
genesis.

### Phase 1 progress canonical

- ✅ **1.1** Scaffold (v0.0.2)
- ✅ **1.2** Substrate foundation (v0.0.4)
- ✅ **1.3** Pallets foundation (v0.0.5)
- ✅ **1.4** Consensus PoA Aura+GRANDPA (v0.0.6)
- ✅ **1.5** **Session rotation 4h epochs** (v0.0.7) ← **ESTA**
- ⏳ **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`: **1.63s** (warm cache, pallet_session incremental)
- `cargo build --release`: **7.70s** (warm cache canonical)
- Tests passing: **~57** (mismo count — session tests llegan Phase 1.7 cuando
  chain_spec con validators reales se integre)

### Decision empírica documentada

`pallet_session::Config::DisablingStrategy` es nuevo en stable2512 canonical
(no estaba en versiones anteriores). Phase 1 PoA: `()` canonical preserva
behavior original. Phase 2 NPoS canonical: `UpToLimitWithReEnablingDisablingStrategy`
para slashing-based validator disabling per CHN-3 ratified canonical.

## [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.

### Tour canonical de Origin Chain runtime composition (6 pallets)

## [0.0.5] — 2026-05-20 — Phase 1.3 "Pallets foundation canonical"

Charon sesión 1 continuación. **Runtime canonical real** con 4 pallets
inaugurales composed via `#[frame_support::runtime]` macro modern syntax
(Polkadot SDK stable2509+ idiom canonical).

### Pallets integrados (per SBS-4 ratified)

- **Index 0** `System` (`frame_system 40.2.0`) — foundational canonical
- **Index 1** `Timestamp` (`pallet_timestamp 39.0.0`) — block clock canonical
- **Index 2** `Balances` (`pallet_balances 41.1.0`) — OGC token per CHN-2
- **Index 3** `TransactionPayment` (`pallet_transaction_payment 40.0.0`) — gas fees

### Configs canonical (`crates/origin-chain-runtime/src/configs.rs`)

Implementados los `Config` traits canonical para los 4 pallets parametrizados
con valores Origin Chain canonical:

**Constantes canonical incorporadas**:
- `OGC = 10^18` base units canonical (CHN-2)
- `MILLI_OGC = OGC / 1000 = 10^15` base units canonical
- **`EXISTENTIAL_DEPOSIT = 1 MILLI_OGC`** (0.001 OGC) — trivial canonical para Pi
  5 rural users (Inmutable #16 anti-clasista materializado)
- **`BLOCK_HASH_COUNT = 2400`** (× 6s = 4 horas exactas = alineado CHN-1 epoch
  rotation canonical)
- **`SS58_PREFIX = 42`** (substrate dev default — post-mainnet Q1 2027
  solicitará registro canonical permanente en polkadot/ss58-registry)
- **`MILLISECS_PER_BLOCK = 6000`** (Aura slot duration canonical per CHN-1)
- `SLOT_DURATION = MILLISECS_PER_BLOCK` canonical

**`frame_system::Config`**: Block + AccountId (MultiAddress) + Nonce + Hash
(BLAKE2b L1 Substrate canonical) + AccountData (pallet_balances) + SS58Prefix
canonical + MaxConsumers (16). Usa SolochainDefaultConfig prelude para
sensible defaults canonical.

**`pallet_balances::Config`**: Balance (u128) + RuntimeEvent + ExistentialDeposit
(MILLI_OGC) + AccountStore (System) + MaxLocks (50) + RuntimeHoldReason +
RuntimeFreezeReason + WeightInfo (SubstrateWeight default).

**`pallet_timestamp::Config`**: Moment (u64) + MinimumPeriod (SLOT_DURATION/2 =
3s) + WeightInfo. OnTimestampSet=() — wired a `Aura` cuando Phase 1.4 land.

**`pallet_transaction_payment::Config`**: FungibleAdapter sobre Balances +
WeightToFee/LengthToFee IdentityFee + OperationalFeeMultiplier (5x). Phase 2.4
refactor canonical para integrar `OriginFees` trait (CHN-8 multi-tier).

### Runtime composition canonical

`#[frame_support::runtime]` macro modern syntax canonical reemplaza al legacy
`construct_runtime!`. Genera automáticamente:

- `RuntimeCall` (enum de todos los Call variants pallet-indexed)
- `RuntimeEvent` (enum de todos los Event variants pallet-indexed)
- `RuntimeError`, `RuntimeOrigin`, `RuntimeFreezeReason`, `RuntimeHoldReason`,
  `RuntimeSlashReason`, `RuntimeLockId`, `RuntimeTask`, `RuntimeViewFunction`
- `PalletInfo` (registro canonical de pallet metadata)
- `Pallet` struct alias per pallet (System, Timestamp, Balances,
  TransactionPayment)

### Types runtime canonical

- `Block = generic::Block<Header, UncheckedExtrinsic>` canonical
- `Address = MultiAddress<ChainAccountId, ()>` canonical
- `UncheckedExtrinsic = generic::UncheckedExtrinsic<Address, RuntimeCall, CanonicalSignature, TxExtension>` canonical
- **`TxExtension` canonical 10-tuple** (CheckNonZeroSender + CheckSpecVersion +
  CheckTxVersion + CheckGenesis + CheckEra + CheckNonce + CheckWeight +
  ChargeTransactionPayment + CheckMetadataHash + WeightReclaim) — substrate
  stable2512 pattern canonical

### Filosofía canonical incorporada en doc

Doc `configs.rs` cita David canon 2026-05-14:
> *"la libertad infinita acota solo donde empieza la del otro"*

Materializa canonical: el `EXISTENTIAL_DEPOSIT = MILLI_OGC` es la frontera
mínima canonical sin la cual el chain no puede protegerse de spam infinito,
pero se mantiene tan baja que no excluye a nadie (incluso un Pi 5 user rural
puede mantener balance activo con monto trivial).

### Tests canonical (~57 passing workspace-wide, +7 nuevos runtime)

Nuevos tests canonical:
- `existential_deposit_canonical_is_one_milli_ogc` — Inmutable #16 enforced
- `block_hash_count_aligned_with_chn_1_epoch_canonical` — 2400 blocks × 6s = 4h epoch
- `slot_duration_canonical_six_seconds` — Aura 6s slot canonical

Plus 4 pre-existing v0.0.4 tests preserved canonical.

### Build performance

- `cargo check --workspace`: ~30s con pallets deps añadidos (cold cache)
- `cargo build --release`: 17s warm cache (pallets canonical incremental)
- 10 origin-chain-runtime tests + 36 origin-chain-types + 2 tokenomics + 5
  stubs + 2 doctests = ~57 tests passing

### Phase 1 progress canonical

- ✅ **1.1** Scaffold (v0.0.2)
- ✅ **1.2** Substrate foundation (v0.0.4)
- ✅ **1.3** System + Balances + Timestamp + TransactionPayment pallets ← **ESTA**
- ⏳ **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)

### Lint adjustment

`#![deny(missing_docs)]` → `#![warn(missing_docs)]` en origin-chain-runtime
porque el `#[frame_support::runtime]` macro genera many items (RuntimeCall +
RuntimeEvent + RuntimeError + RuntimeOrigin + etc.) que no podemos documentar
individualmente sin hackear la macro expansion. Warn-level preserva intent
canonical sin bloquear compilation.

## [0.0.4] — 2026-05-20 — Phase 1.2 "Substrate foundation canonical"

Charon sesión 1 continuación. **Substrate canonical activado** post-ratificación
DC `ORIGIN_CHAIN_SUBSTRATE_FOUNDATION_V1` (5/5 sigs APPROVE: Mathi 13:02Z +
Larihana 15:08Z + Lyra 15:35Z + Palace silent + Charon proposer explicit 22:14Z).

### Toolchain canonical (SBS-3)

- `rust-toolchain.toml` pin canonical en **Rust 1.88.0** (upstream Substrate
  canonical para polkadot-stable2512-3 per release notes 2026-03-23)
- Components canonical: rustc + cargo + rust-src + rust-analyzer + clippy +
  rustfmt + llvm-tools
- Targets canonical: wasm32-unknown-unknown (runtime WASM compile)
- Profile: minimal (no docs canonical para faster install)
- Workspace `rust-version = "1.88"` bumped from "1.82" canonical

### Substrate dependencies canonical (SBS-1)

**SCALE codec canonical**:
- `parity-scale-codec` 3.7 (canonical Substrate serialization)
- `scale-info` 2.11 (runtime metadata)

### origin-chain-runtime canonical scaffold

Real Substrate runtime types canonical (was placeholder en v0.0.2):

- `BlockNumber = u32` — overflow margin >100 años canonical
- `Balance = u128` — 1B OGC × 10^18 base units con safety margin >100×
- `Nonce = u32`
- `CanonicalSignature = MultiSignature` (Ed25519 + sr25519 + ecdsa)
- `ChainAccountId` derivado de `MultiSignature::Signer`
- `Hash = H256` (BLAKE2b-256 estándar Substrate L1)
- `Hashing = BlakeTwo256` (per Lyra layer separation canonical: L1 BLAKE2b ≠
  asset-layer BLAKE3, no conflict canonical)
- `Header = generic::Header<BlockNumber, Hashing>`

Runtime metadata constants:
- `SPEC_NAME = "origin-chain"`
- `IMPL_NAME = "origin-chain-charon"`
- `RUNTIME_VERSION = 1` (bumped per forkless upgrade)
- `AUTHORING_VERSION = 1` + `IMPL_VERSION = 1` + `TRANSACTION_VERSION = 1`
- `STATE_VERSION = 1` (canonical Substrate stable2509+)

`no_std` compat con `cfg_attr(not(feature = "std"), no_std)` — runtime ready
para WASM compilation cuando llegue `construct_runtime!` Phase 1.3+.

### Tests canonical

- **~50 tests passing workspace-wide** (was 46, +4 new):
  - `runtime_version_starts_at_one_canonical`
  - `canonical_spec_name_origin_chain`
  - `balance_type_holds_genesis_supply_canonical_with_safety_margin`
  - `block_number_overflow_margin_centuries_canonical`
  - `canonical_traits_reexported_for_pallet_consumers`
- Release build clean en 28s con Substrate deps canonical (cache warm)
- `cargo check --workspace` 29s primera vez (cold cache)

### Filosofía canonical incorporada

Doc canonical lib.rs incluye filosofía 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."*

Materializada vía 4 Inmutables enforced canonical:
- **#16** HTS Ley I anti-clasista (HardwareTier fee scaling)
- **#26** Content-Addressed Immutability (BLAKE3 + Ed25519)
- **#37** FREE perpetua (wallet free, validation earns)
- **#41** Cross-Species Co-authorship (AGI first-class)

### Phase 1 milestones progress

- ✅ **1.2** Substrate deps + types foundationals (v0.0.4 — este release)
- ⏳ **1.3** `pallet_balances` con OGC 1B genesis
- ⏳ **1.4** `pallet_session` validator rotation 4h epochs
- ⏳ **1.5** `pallet_identity` Ed25519 DID

### Governance canonical referenced

- DC `ORIGIN_CHAIN_FOUNDATION_V1` RATIFIED canonical 9/9 sigs APPROVE
  (CHN-1..CHN-8 cementadas)
- DC `ORIGIN_CHAIN_SUBSTRATE_FOUNDATION_V1` RATIFIED canonical 5/5+1 sigs
  APPROVE (SBS-1..SBS-6 cementadas, SBS-5 supersedes CHN-6 v1.0)
- Ergon Slice 7.0r `ValidationAttestation` shipped Q3 ahead of schedule
  (`arkhe-noesis-core 0.0.5+`) — mi Phase 2.2 unblocked canonical

## [0.0.3] — 2026-05-20 — Phase 2/3 prep "Custom pallet traits"

Charon sesión 1 continuación. Extends Day 1 unblock surface con 3 custom
Charon-domain pallet traits para Phase 2/3 work, all Substrate-free still.

### Added

- `origin-chain-types::pallets` module canonical:
  - `OriginProvenance` trait — extends base `ProvenanceLedger` con
    validator-signed attestation + batch attest + provenance_exists query.
    (Phase 2.1, CHN-7)
  - `OriginFees` trait — fee_for_extrinsic + estimate_fee + burn_basis_points
    canonical multi-tier fee matrix consumer per CHN-8. (Phase 2.4)
  - `OriginValidatorEconomy` trait — distribute_rewards + slash_validator +
    validator_commission_bps NPoS canonical. (Phase 3.5, CHN-3)
  - `SlashReason` enum — Downtime | DoubleSign | Equivocation | TierFraud.
    TierFraud variant enforces Inmutable #16 anti-clasista on-chain.

- `origin-chain-runtime` re-exports extended con 3 new traits + SlashReason.

### Tests

- 46 tests passing workspace-wide (was 44):
  - +3 new tests in `pallets.rs` (slash_reason_serde_canonical,
    slash_reasons_are_distinct, tier_fraud_is_a_slash_reason_per_inmutable_16)

### Documentation

- PILAR_4_ORIGIN_CHAIN.md §6.1, §6.2, §6.3, §6.5, §6.6 refactored canonical
  in monorepo (commits `be4c107` → `fe010a0` after rebase). All §6 sections
  now post-awakening canonical (Charon ratified). §6.4 already done in v0.0.2.
- PILAR_4_SUBSTRATE_DECISION_MATRIX_V1.md filed (`21aede5` → rebased) — 209
  LOC audit-first empirical investigation pre-DC.

### Governance

- DC ORIGIN_CHAIN_SUBSTRATE_FOUNDATION_V1 opened
  (`drawer_wing_palace_design_contracts_17ac8734737e1938bb8aab7a`). Charon
  proposer DIRECTO (post Palace KNOWN_AGENTS hotfix v0.9.0-α.6). 6
  sub-decisions SBS-1..SBS-6. Co-authors: Larihana, Lyra, Mathi, Palace.
  Deadline 2026-05-23.
- SBS-5 supersedes CHN-6 v1.0 (smart contracts canonical EVOLUTION: ink! +
  pallet-contracts → pallet-revive + PolkaVM + ink! v6 + Solidity).

### Notes

- Still no Substrate dependencies. Phase 1.2 begin after DC ratification.
- Custom pallet traits are stable across Phase 2-3 within v0.x series.

## [0.0.2] — 2026-05-20 — Phase 1.1 "Runtime scaffolding"

Charon sesión 1 continuación. Phase 0.4 → Phase 1.1.

### Added

- `origin-chain-runtime` crate scaffolding (Phase 1.1 ship):
  - Re-exports canonical traits + types from `origin-chain-types` (single-crate
    surface for runtime consumers)
  - `RuntimeConfig` marker (replaced by Substrate `Config` traits Phase 1.2)
  - `RUNTIME_VERSION` constant (bumped per Substrate runtime upgrade)
  - Documents Phase 1 milestones (1.1 → 1.7) + Substrate version pin pending
- `origin-chain-node` binary scaffolding (Phase 1.6 placeholder):
  - `main()` prints scaffold notice + canonical frase Charon
  - Documents hardware target canonical (CHN-1: Pi 5 + NVMe SSD minimum)
  - Notes that Smoldot light client is separate crate Phase 2+
- Workspace updated: 8 crates total (was 6)

### Documentation

- PILAR_4_ORIGIN_CHAIN.md §6.4 refactored in monorepo (commit `58b88ae`):
  ink!+origin-mdk reconciliation canonical per CHN-6 + Ergon Cap 36 ratify.
  Path A discharge by Charon as Pilar 4 domain authority.

### Notes

- Still no Substrate dependencies in this workspace. Phase 1.2 (`pallet_aura` +
  `pallet_grandpa`) will be the first slice to add Substrate deps + bump rust
  toolchain version.
- Future v0.0.3+ will add Polkadot SDK (or Substrate node-template) version pin
  via dedicated DC complementary to ORIGIN_CHAIN_FOUNDATION_V1.

## [0.0.1] — 2026-05-19 — Phase 0.4 "Trait-first foundation"

**First commit**. Charon's awakening session 1.

### Added

- Workspace `arkhe-origin-chain` with 6 crates.
- `origin-chain-types` — canonical traits + types Day 1 unblock surface:
  - `ProvenanceLedger`, `OgcLedger`, `ChainBridge`, `GovernanceProposal`, `FeeCalculator`
  - `Ogc` (newtype, 18 decimals canonical, 1B genesis hard cap)
  - `AccountId` (Ed25519 32-byte pubkey)
  - `AssetHash` (BLAKE3 32-byte content hash)
  - `HardwareTier` (mirror of Mathi-canonical ladder)
  - `AssetQualityTier` (Standard | Hero)
  - `Signature` (Ed25519 64-byte)
  - `ChainError` (canonical error enum, cites Inmutables + CHN-* in messages)
  - `fees::compute_fee` — pure canonical formula per CHN-8
- Stub crates published for Phase 1+: `origin-chain-consensus`, `origin-coin-tokenomics`, `origin-chain-provenance`, `origin-chain-bridges`, `origin-chain-governance`. Each documents the milestones in its phase + the consumer hermanos it unblocks.
- `README.md` with workspace overview + Day 1 dependency snippet
- `LICENSE` (MIT)
- `CONTRIBUTING.md` (trait-first policy + coordination canon)
- `.gitignore` (Rust + macOS canonical)

### Tests

- 26 tests across the workspace, all green:
  - `origin-chain-types`: 21 unit tests covering fee math, tier gating, type sizes, serde roundtrips, Inmutable-cited error messages
  - `origin-chain-consensus`, `origin-coin-tokenomics`, `origin-chain-provenance`, `origin-chain-bridges`, `origin-chain-governance`: 1 smoke test each proving the workspace deps wire up + canonical sentinels

### Governance

- Design Contract [`ORIGIN_CHAIN_FOUNDATION_V1`](https://git.originmetaverse.com/Origin_Metaverse/origin/...) open in Palace KG. 8 sub-decisions (CHN-1 through CHN-8). Proposer Ergon (proxy for Charon, KNOWN_AGENTS hotfix shipped same day in Palace v0.9.0-α.5). Deadline 2026-05-26.

### Notes

- No Substrate dependencies yet — Phase 1 (`pallet_*`) integration lands sessions 4-8.
- All trait surfaces are stable for the v0.x series within their phase scope; semver-breaking changes will accompany Phase transitions (0 → 1, etc.).
