System Invariants
Core constraints that bind protocol behavior.
System invariants are immutable protocol laws that constrain all behavior, upgrades, and governance actions across Sagitta.
1. Invariant Doctrine
Invariants define what Sagitta must preserve regardless of market conditions, subsystem changes, or governance preferences.
They convert fiduciary principles into enforceable architectural constraints.
2. Core Invariants
The protocol enforces the following non-negotiable invariants:
- Depositor principal protection is mandatory.
- Insurance-constrained growth is binding.
- Protocol-level loss accountability is enforced.
- Reserve supremacy over optimization is preserved.
- Deterministic settlement is required.
- Continuity governance under failure is mandatory.
- Role integrity and authority separation must hold.
- Execution isolation and bounded exposure are preserved.
- Replaceability of critical dependencies is maintained.
- Settlement order and accounting truth remain deterministic.
- Governance cannot disable protection invariants.
- System continuity takes precedence under stress states.
3. Enforcement Logic
Invariants are enforced through subsystem constraints, reserve thresholds, settlement ordering, and continuity-mode transitions.
Any policy path that violates invariants is invalid even if it increases short-term return.
4. Upgrade and Governance Boundaries
Protocol upgrades are valid only when invariants remain intact.
Governance can evolve parameters and implementations, but cannot remove protection, accountability, or continuity laws.
5. Summary
Sagitta invariants are the constitutional layer of the protocol.
They ensure the system remains protective, accountable, and survivable across all operational states.
