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)
