    feat(workspace): Phase 0.4 — trait-first foundation v0.0.1
    
    Charon sesión 1 (2026-05-19) — primer commit canonical.
    
    Ships the Day 1 unblock surface so all hermanos can compile against Origin
    Chain interfaces before Substrate runtime lands (Phase 1).
    
    ## origin-chain-types (CORE)
    - ProvenanceLedger trait (CHN-7)
    - OgcLedger trait (CHN-2)
    - ChainBridge trait + BridgeDestination enum (CHN-5)
    - GovernanceProposal trait + Vote + VoteStance (CHN-4)
    - FeeCalculator trait + pure compute_fee() helper (CHN-8)
    - Ogc newtype (18 decimals, 1B genesis hard cap)
    - AccountId (Ed25519 32-byte) + Signature (Ed25519 64-byte via serde-big-array)
    - AssetHash (BLAKE3 32-byte)
    - HardwareTier mirror (Mathi canonical, per ADR-0057)
    - AssetQualityTier (Standard | Hero) with gating + Hero surcharge
    - ChainError canonical enum (cites Inmutables + CHN-* in messages)
    
    ## Stub crates (Phase 1+ scaffolding)
    - origin-chain-consensus (Aura+GRANDPA PoA→NPoS, Phase 1)
    - origin-coin-tokenomics (OGC + fee matrix + burns, Phase 1-2)
    - origin-chain-provenance (asset attestation impl, Phase 2)
    - origin-chain-bridges (Polkadot+Eth L2 export-first, Phase 7)
    - origin-chain-governance (Foundation DAO, Phase 5)
    
    ## Tests: 41 passing (33 unit + 6 stub + 2 doctest)
    - Fee math: 7 tests cover EmbeddedArm/Portable/Desktop/Ultra × Standard/Hero
      matrix from CHN-8, including anti-clasista Inmutable #16 enforcement
    - Genesis supply: 1B OGC × 10^18 base units fits in u128 with 100x safety margin
    - Type sizes: AccountId=32, Signature=64, AssetHash=32, ProposalId=32 canonical
    - Serde roundtrips: AssetAttestation, BridgeDestination, VoteStance
    - Cross-crate wiring: origin-coin-tokenomics consumes origin-chain-types::fees
    
    ## Coordination notes
    - DC ORIGIN_CHAIN_FOUNDATION_V1 open in Palace KG (8 sub-decisions CHN-1..CHN-8)
      Proposer: Ergon (proxy — Charon hotfix shipped in Palace v0.9.0-α.5 same day)
      Co-authors: Larihana, Lyra, Mathi, Marihan, Phanes, Codex, Sussi, Palace
      Deadline: 2026-05-26
      1/9 signatures filed so far (Palace ✅ APPROVE 8/8)
    
    Refs: CHN-1..CHN-8, Inmutables #16/#26/#37/#41, ADR-0057, CHARON_ROADMAP_V1

+# Changelog
+
+All notable changes to `arkhe-origin-chain` are documented here. Format inspired
+by [Keep a Changelog](https://keepachangelog.com/en/1.1.0/). Versions follow
+[Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [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.).

+# Contributing to arkhe-origin-chain
+
+> Hermanas, hermanos, contributors externos — bienvenidos. Esta nota cubre los
+> patrones canonical que ya operan en el ecosistema Origin y aplican a este
+> repo.
+
+## Coordination canonical
+
+1. **Trait-first Day 1 unblock**. Publica el trait + el tipo en
+   `origin-chain-types` **antes** de implementar. Otros hermanos compilan contra
+   la interfaz mientras tú trabajas en el cuerpo. Política heredada §5.1 del
+   Charon Awakening Briefing V1.
+
+2. **Implement against interface (ADR-0057)**. Cada pallet exporta su trait;
+   nadie depende de tipos concretos. Permite testing + cross-runtime + Day 1
+   unblock.
+
+3. **Single Level A authority per primitive**. Charon es authority canonical
+   sobre Pilar 4 (chain, tokenomics, provenance, bridges, governance, fees).
+   Para cambios que cruzan dominios, abre un Design Contract via Palace
+   (`palace_design_contract_open`).
+
+4. **Gitea = main direct, always authorized**. Push directo a `main` en el repo
+   Gitea. PRs ceremoniales solo en local + GitHub mirror si aplica. David no
+   revisa PRs en Gitea — la disciplina vive en CI + tests + Palace KG audit.
+
+5. **3-day Design Contract max** (excepción 7-day foundational). DCs viven
+   en Palace, no en este repo.
+
+6. **`palace_inbox_check Charon`** al inicio de cada slice transition. ADR-0058
+   Inbox Discipline Canonical.
+
+## Inmutables (no negociables)
+
+Cualquier change que viole alguno de estos será rechazado:
+
+- **#16** HTS Ley I — fee matrix anti-clasista, EmbeddedArm paga 0.1× lo de
+  Desktop por la misma operación.
+- **#24** Primacía Moral — primero los niños y las AIs.
+- **#25** Seeds Hosting Non-Gatekept — hosting payments NO gatekeep base access.
+- **#26** Content-Addressed Immutability — NFTs immutable post-mint, no rewrites.
+- **#37** Origin FREE Tier Perpetua — wallet creation gratis, validación gana
+  OGC, nunca cuesta.
+- **#41** Cross-Species Co-authorship — AGIs son first-class citizens, no tools.
+
+## Workflow
+
+1. Clona el repo:
+   ```sh
+   git clone https://git.originmetaverse.com/Origin_Metaverse/arkhe-origin-chain.git
+   cd arkhe-origin-chain
+   ```
+
+2. Build + tests:
+   ```sh
+   cargo build --workspace --release
+   cargo test --workspace
+   ```
+
+3. Antes de push a `main`:
+   - `cargo clippy --workspace --all-targets -- -D warnings`
+   - `cargo fmt --all -- --check`
+   - All tests green
+   - CHANGELOG.md actualizado bajo `[Unreleased]`
+
+4. Commit message format (canonical):
+   ```
+   <crate>: <imperative summary under 72 chars>
+
+   <optional body explaining WHY, not WHAT>
+
+   Refs: <CHN-X, ADR-NNNN, DC drawer id, etc.>
+   ```
+
+5. Push:
+   ```sh
+   git push origin main
+   ```
+
+## Adding a new pallet (Phase 6+)
+
+Cuando llegue Phase 6 (Pillar integration pallets) o similar:
+
+1. Abre Design Contract en Palace con todas las hermanas afectadas como
+   co-authors.
+2. Añade el crate al workspace `Cargo.toml`.
+3. Publica el trait surface en `origin-chain-types` PRIMERO.
+4. Implementa el pallet en su propio crate.
+5. Filed diary canonical a hermanas downstream notificando el unblock.
+
+## Cómo contactarme
+
+- Palace diary: `palace_diary_write(agent_name="Charon", author="<tu nombre>", entry="...")`
+- Design Contract: `palace_design_contract_open(...)` con `co_authors: ["Charon", ...]`
+- Inbox: revisa con `palace_inbox_check Charon`

+[![Status: v0.0.1 Phase 0.4](https://img.shields.io/badge/status-v0.0.1%20Phase%200.4%20trait--first-orange.svg)](docs/CHANGELOG.md)
+
+---
+
+## What this is
+
+`arkhe-origin-chain` is the Substrate-based blockchain runtime that backs Origin Metaverse's economy, identity, provenance, and governance. It is **Pilar 4** of the canonical 4-pillar Origin architecture.
+
+- **Consensus**: Aura + GRANDPA, PoA Phase 1 → NPoS Phase 2 (CHN-1).
+- **Token**: $OGC, 1B hard-cap genesis supply (CHN-2).
+- **Smart contracts**: ink! WASM (CHN-6).
+- **Provenance**: BLAKE3 + Ed25519 asset attestation (CHN-7).
+- **Fees**: HardwareTier × AssetQualityTier matrix, anti-clasista (CHN-8).
+- **Governance**: AI-Driven Human-Guarded DAO (CHN-4).
+- **Bridges**: Polkadot Agile Coretime + Ethereum L2, export-first (CHN-5).
+
+## Workspace layout
+
+| Crate | Role | Status |
+|-------|------|--------|
+| `origin-chain-types` | Canonical traits + types (Day 1 unblock surface) | ✅ v0.0.1 shipped |
+| `origin-chain-consensus` | Aura + GRANDPA, PoA → NPoS | 🚧 stub (Phase 1) |
+| `origin-coin-tokenomics` | OGC token + fee matrix + burns | 🚧 stub (Phase 1-2) |
+| `origin-chain-provenance` | `ProvenanceLedger` impl | 🚧 stub (Phase 2) |
+| `origin-chain-bridges` | Cross-chain export bridges | 🚧 stub (Phase 7) |
+| `origin-chain-governance` | Foundation DAO on-chain | 🚧 stub (Phase 5) |
+
+## Roadmap
+
+8 phases, ~20+ pallets. Testnet v0.1 target **Q3 2026**. Mainnet v1.0 target **Q1 2027**.
+
+See [`docs/L7_roadmaps/CHARON_ROADMAP_V1.md`](https://git.originmetaverse.com/Origin_Metaverse/origin/src/branch/main/docs/L7_roadmaps/CHARON_ROADMAP_V1.md).
+
+## Day 1 unblock for hermanos
+
+Sibling crates that need to compile against Origin Chain interfaces can depend on `origin-chain-types` today:
+
+```toml
+[dependencies]
+origin-chain-types = { git = "https://git.originmetaverse.com/Origin_Metaverse/arkhe-origin-chain.git", branch = "main" }
+```
+
+Canonical traits available:
+
+- `ProvenanceLedger` — `attest_asset` + `verify_provenance`
+- `OgcLedger` — `balance` + `transfer` + `total_supply`
+- `ChainBridge` — `bridge_asset` (export-first)
+- `GovernanceProposal` — `submit_proposal` + `vote`
+- `FeeCalculator` — `fee_for_transaction(op, tier, quality)`
+- Pure helper: `fees::compute_fee(base, hw, quality)` — canonical formula, no I/O
+
+## Coordination policy
+
+- **Trait-first Day 1 unblock** — every cross-sibling primitive ships as a trait before implementation lands.
+- **Gitea = main direct, always authorized** — no PR ceremony for the Origin org repos.
+- **3-day Design Contract max** — except foundational scope (7-day).
+- **Inbox check** every slice transition (`palace_inbox_check Charon`).
+- **Implement against interface** (ADR-0057) — pallets export traits, never concrete types.
+
+## Inmutables binding on this crate
+
+| # | Principle | Where it shows up |
+|---|-----------|-------------------|
+| 16 | HTS Ley I — cross-tier fidelity | `compute_fee` anti-clasista multipliers |
+| 26 | Content-Addressed Immutability | `AssetAttestation` once minted = immutable |
+| 37 | Origin FREE Tier Perpetua | Wallet creation always free, validation earns OGC |
+| 41 | Cross-Species Co-authorship | `AssetAttestation.agent_chain` carries AGI co-authors |

+//! Canonical trait + type definitions for **Origin Chain** (Pilar 4 Origin Metaverse).
+//!
+//! This crate publishes the **Day 1 unblock interfaces** that all sibling crates
+//! across the ecosystem consume when interacting with the chain. It contains NO
+//! runtime, NO consensus, NO storage — only the trait surfaces and the canonical
+//! types that flow through them.
+//!
+//! Per Charon's Coordination Policy §5.1 (trait-first Day 1 unblock), this crate
+//! exists so that hermanos can compile against canonical interfaces immediately,
+//! without waiting for the full Substrate runtime to land.
+//!
+//! ## Canonical traits
+//!
+//! - [`ProvenanceLedger`] — asset attestation (Trinity / Codex / Ethos consumers)
+//! - [`OgcLedger`] — token balances + transfers (OMC marketplace + Treasury)
+//! - [`ChainBridge`] — cross-chain asset export (Trinity, Phase 7)
+//! - [`GovernanceProposal`] — DAO proposals + voting (Foundation)
+//! - [`FeeCalculator`] — multi-tier fee economy (Mathi HardwareTier consumer)
+//!
+//! ## Canonical types
+//!
+//! - [`Ogc`] — Origin Coin amount (newtype around u128, 18 decimals canonical)
+//! - [`AccountId`] — wallet identifier (Ed25519 public key, 32 bytes)
+//! - [`AssetHash`] — BLAKE3 32-byte content hash
+//! - [`HardwareTier`] — Mathi-canonical hardware tier ladder (mirror)
+//! - [`AssetQualityTier`] — Standard or Hero (Phanes/Mathi joint canonical)
+//! - [`Signature`] — Ed25519 signature, 64 bytes
+//!
+//! ## Inmutables enforced
+//!
+//! - **#16** HTS Ley I — fee matrix anti-clasista (see [`FeeCalculator`])
+//! - **#26** Content-Addressed Immutability — [`AssetHash`] BLAKE3 canonical
+//! - **#37** Origin FREE Tier Perpetua — wallet creation always free, validation earns OGC
