Engineering Design Principles: 1. Immutable Vows: Vows start as draft commitments and become cryptographically sealed once criteria are configured, preventing post-hoc goalpost shifts. 2. Evidence Decoupling: Artifact attestations (codebases, logs, telemetry, reports) are registered with provenance hashes. Registration records evidence without pre-approving satisfaction. 3. Storage Isolation: Non-deterministic closures in GenVM only capture plain in-memory Python copies to guarantee storage safety across validator rounds. 4. Decisive Equivalence: Validators reach consensus over structured decisive verdict keys while tolerating natural language variations in LLM summaries. 5. Fail-Closed Guarantees: Missing evidence or unverifiable criteria default to INSUFFICIENT_EVIDENCE or CLAUSE_BREACHED. 6. DeFi Composability: Exposes is_vow_clause_fulfilled() for external escrows, payment splitters, and DAO governance modules to trigger automated settlements.
