## [Unreleased]

## [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.).
