## [Unreleased]

## [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.).
