| Inmutable | Enforcement |
|---|---|
| #16 HTS anti-clasista | escrow_fee_bps capped 5% BM V2 §5.3 ceiling. Pi 5 institutional rate Phase 3.x |
| #26 Content-Addressed Immutability | terms_hash + description_hash BLAKE3 inmutable post-deploy |
| #37 Free perpetua | 9 read methods sin payment (state, depositor, beneficiary, milestones, etc.) |
| #41 AGI Cross-Species | AGI accounts pueden ser any party (depositor, beneficiary, arbiter) |
Resolution canonical (Tribunal options)
4 resolution patterns canonical para Tribunal:
- ReleaseToBeneficiary: 100% remaining → beneficiary (work completed satisfactorily)
- RefundToDepositor: 100% remaining → depositor (work not delivered / fraud)
- SplitFifty: 50/50 split (partial completion / shared responsibility)
- Custom { depositor_bps, beneficiary_bps }: arbitrary split (e.g., 30/70 partial completion)
Invariant compile-detect: depositor_bps + beneficiary_bps == 10_000 (100%).
Tests canonical (3 unit tests)
constructor_canonical_invariants— valid params + initial state Createdexcessive_fee_rejected_canonical— 6% fee rejected (>5% ceiling)same_party_depositor_beneficiary_rejected— same address rejected
