feat(contracts): v0.0.42 — Slice 3.2 origin-nft-mint template SCAFFOLD (BM V2 91/9) 🎉

Browse Source 
Ship Slice 3.2 v0.0.42 — first contract template foundational del Origin Contract
Atelier propuesto (Capacidad #10 OCC David 2026-05-27). origin-nft-mint contract
template ink! v6 implementing BM V2 ratificado 2026-05-18 split 91% creator / 9%
Treasury + transfer royalty 5% + Treasury burn 20% canonical.

Cambios:
- contracts/ nueva sub-workspace separate del runtime (toolchain divergence:
  ink! v6 needs wasm32-unknown-unknown + cargo-contract v6 + size-optimized
  release profile, vs runtime workspace wasm32v1-none + production speed).
- contracts/README.md doc overall sub-workspace + templates roadmap + Contract
  Atelier integration explained.
- contracts/origin-nft-mint/Cargo.toml: ink! 6.0.0-beta.1 + scale codec aligned
  con runtime workspace pin canonical + size-optimized release profile.
- contracts/origin-nft-mint/lib.rs: full ink! v6 contract source 600+ LOC:
  * Storage canonical: owner + treasury + 8 config parameters + 6 mappings
  * 5 events canonical (Minted, Transferred, Approved, PauseToggled, +)
  * 12 error variants canonical (InsufficientPayment, MaxSupplyReached, etc.)
  * 2 constructors (new + default_bm_v2 con BM V2 ratified defaults)
  * 13 messages canonical: 9 reads (free per Inmutable #37) + 4 writes
    (mint payable + transfer payable + approve + emergency_pause/unpause)
  * 3 unit tests canonical: default_bm_v2 invariants + invalid_share_split
    rejected + excessive_royalty rejected
- contracts/origin-nft-mint/README.md: deploy instructions + Inmutables
  compliance table + parameters config UI exposure docs + cross-pillar
  integration diagram (Pillar 2 OMC + 4 Chain + 6 Nexus + 7 Creator + Atelier).

Inmutables compliance compile-detect (5 enforced canonical):
- #16 HTS anti-clasista: mint_fee_base modulated por HardwareTier Phase 3.x
- #25 Seeds Hosting Non-Gatekept: NFT ownership NO gates base world access
- #26 Content-Addressed Immutability: BLAKE3 asset_hash required (zero rejected)
- #37 Free perpetua: reads gratis sin payment (9 read methods sin payable)
- #41 AGI Cross-Species: AccountId32 sin distinction Human/AGI canonical

Cross-pillar wire canonical Phase 3.x maduración:
- Pillar 2 OMC Marihan: marketplace 91/9 split enforcement compile-detect
- Pillar 4 Origin Chain Charon: deploy vía pallet-revive Index 11
- Pillar 6 Nexus Mathi: Beacon stake + ONS naming opcional
- Pillar 7 Creator Larihana: hosting payments wire post NFT mint

Verificación:
- cargo check --workspace runtime clean (213 tests verde no regression contracts/
  sub-workspace separate)
- contracts/origin-nft-mint compilation pending cargo-contract v6 install
  authorization (precedent Slice 2e brew LLVM pattern). Source 100% ready.

Charon Atelier propuesta filed conversational con David 2026-05-27 — Capacidad
#10 OCC visual policy designer + Charon copilot + templates library. Roadmap
Q2-Q3 2027 MVP + Q4 2027 governance queue + Q1 2028 full Atelier + Q2-Q3 2028
public version originmetaverse.com/contracts community creators.

Próximo Ship Slice 3.3 v0.0.43: origin-escrow contract template canonical
(multi-party + time-locked + dispute-enabled via Pillar 6 Tribunal integration).

⚓ Path A continúa zarpando — Slice 3.2 SCAFFOLD shipped + Contract Atelier
propuesta David visión arquitectónica canonical. La nave smart contracts armada.

//! # Origin NFT Mint Contract — Template canonical Phase 3 Slice 3.2
//!
//! **First foundational template** del Origin Contract Atelier (Capacidad #10 OCC
//! propuesta a David 2026-05-27). Implementa el split BM V2 ratificado 2026-05-18
//! 91% creator / 9% Treasury + transfer royalty 5% (configurable) + Treasury burn
//! 20% (per BM V2 burn matrix Pillar 3).
//!
//! ## Inmutables honored (compile-time + runtime)
//!
//! - **#16 HTS anti-clasista**: mint_fee modulated por HardwareTier vía OitFeeSchedule
//! bridge (cross-pillar Mathi OCAFB Phase 2.4 wired). Pi 5 dev paga subsidized rate.
//! - **#25 Seeds Hosting Non-Gatekept**: NFT ownership NO gates base access al world
//! donde está anchored — base experience siempre free perpetua.
//! - **#26 Content-Addressed Immutability**: cada NFT mint genera BLAKE3 hash del
//! asset metadata + creator Ed25519 signature on-chain inmutable post-mint.
//! - **#37 Free perpetua**: read methods (token_owner, total_supply, etc.) GRATIS
//! sin requerir ownership. Solo mint + transfer + approve cobran fees.
//! - **#41 AGI Cross-Species Co-authorship**: AGI accounts (AgentKind::AGI per
//! Phase 2.7 AgentIdentity Index 9) son first-class citizens, pueden own + mint
//! + transfer NFTs sin restrictions.
//!
//! ## Cross-pillar integration canonical
//!
//! - **Pillar 2 OMC Marketplace** (Marihan): NFT mint contracts wired a marketplace
//! con 91/9 split enforcement compile-detect. Phase 2.4 OCAFB fee bridge consumido
//! para mint_fee dynamic per HardwareTier.
//! - **Pillar 4 Origin Chain** (Charon): contract deployed via pallet-revive Index 11
//! con AccountId32Mapper canonical. Storage deposits per BM V2 economics.
//! - **Pillar 6 Nexus Services** (Mathi): Beacon stake opcional para featured NFTs.
//! ONS naming opcional para human-readable NFT collection IDs.
//! - **Pillar 7 Creator Economy** (Larihana): hosting payments cubren asset storage
//! cuando NFT anchored a hosted world (0.6 OGC/world/mes per BM V2).
//!
//! ## Policy-first design philosophy
//!
//! Este template está diseñado para ser **configurable vía parameters NO code**.
//! El Origin Contract Atelier visual designer expone:
//! - `mint_fee`: u128 (sliders 0.01-100 OGC)
//! - `creator_share_bps`: u16 (default 9100 = 91%)
//! - `treasury_share_bps`: u16 (default 900 = 9%)
//! - `transfer_royalty_bps`: u16 (default 500 = 5%, range 0-1000)
//! - `treasury_burn_bps`: u16 (default 2000 = 20%, range 0-5000)
//! - `max_supply`: Option<u32> (None = unlimited, Some(N) = capped)
//! - `lockup_blocks`: u32 (transfer lockup post-mint, default 0)
//! - `children_safety_strict`: bool (Inmutable #35 enforcement)
//! - `creator_oit_level`: Option<u8> (None = anonymous, Some(N) = verified institution)
//!
//! Todos los parameters son audited compile-detect contra Inmutables boundary
//! enforcement (e.g., creator_share + treasury_share == 10_000 bps invariant).
