Governance Overrides and Exception Triggers

Defining Safe Paths for Emergency, Dispute, and Fallback Actions Across Clause and DAO Boundaries

6.8.1 Why Exception Triggers Are Needed

In complex, multilateral, high-risk environments, not all scenarios can be modeled in advance. NSF must accommodate:

• Emergency response when simulations are bypassed

• Revocation of rogue credentials without quorum latency

• Mitigation of data poisoning, model tampering, or clause misfires

• Escalation when jurisdictional disputes block execution

• Override of simulation-bound triggers due to real-world conditions

To support this, NSF implements Governance Override Protocols and Exception Triggers, embedded into DAO logic and clause definitions—governed by multisig, timeouts, and signed justifications.

6.8.2 What Is a Governance Override?

An override is a formal DAO action, supported by:

• Threshold multisig signatures

• Justified trigger metadata

• Anchoring in the Audit Layer

• Timed rollback options (if applicable)

• Optional triggering of AppealsDAO or clause-level arbitration

Overrides can:

• Pause or cancel clause execution

• Revoke credentials outside the normal VC lifecycle

• Inject emergency clauses

• Escalate unresolved simulation mismatches

• De-escalate or replace active clauses

---

6.8.3 What Is an Exception Trigger?

An Exception Trigger is a clause-encoded fallback, invoked only when:

• A critical dependency fails

• A defined quorum is unreachable

• A simulation threshold cannot be met

• A trusted signer issues a conditional override VC

They may appear in clause logic as:

if not simulation_valid() and EmergencyOverrideVC.valid()  
then execute fallback_logic()

---

6.8.4 Override Credential Design

Overrides must be signed by:

• Specific governance roles (e.g., DAO Root Signers, Legal Observers)

• With scoped authority (domain, time, clause family)

• Anchored and visible to all oracles and CAC runtimes

Credential example:

{
  "type": "OverrideCredential",
  "issuer": "WHO-DAO",
  "scope": ["OutbreakRelief@*"],
  "condition": "pandemic_index > 0.95 and SimulationRunVC.timeout",
  "valid_from": "2025-08-01T00:00Z",
  "expires": "2025-08-02T00:00Z",
  "signatures": ["0x9a23...", "0x442f..."]
}

---

6.8.5 Fallback Clauses

Clauses may define fallback_logic segments:

fallback_logic() {
  execute [email protected]
  notify SimulationDAO
  suspend Voting until new model hash accepted
}

Fallback clauses must:

• Be pre-anchored

• Reference minimum credential thresholds

• Pass audit layer checks before reuse

---

6.8.6 Appeals and Dispute Escalation Hooks

All overrides or exception paths must optionally emit a dispute hook, which can be:

• Triggered by DAO Auditors

• Initiated by affected jurisdictions

• Escalated to AppealsDAO

Disputes are resolved through:

• Verified audit trails

• Credentialed voting

• Simulation re-execution (if relevant)

• Clause rollback or amendment

---

6.8.7 Timeout Enforcement and Expiry Logic

Overrides and exceptions are not permanent. Each must include:

• Validity windows

• Automatic reversion conditions

• Required DAO review deadlines

• Audit enforcement (e.g., clause cannot run again without renewal)

Fallback execution is suspended if override credential expires or is invalidated by credential oracle consensus.

---

6.8.8 Multisig and Jurisdictional Thresholds

Override activation may require:

• Multiple DAO signatures across jurisdictions

• Weight thresholds by domain (e.g., health vs finance vs environmental)

• Dynamic thresholds (e.g., higher requirement for critical clauses)

Example:

5-of-7 SimDAO members + 2-of-2 PublicHealthDAO signers required to override [email protected].

---

6.8.9 Monitoring, Revocation, and Logging

Overrides and exceptions are logged with:

• Trigger clause

• Credential dependency status

• Simulation failure context

• Governance proof objects

• CAC audit pointer

Revocations or disputes are managed via the Audit Layer, and traced over time for accountability reviews.

---

6.8.10 Controlled Flexibility, Verifiable Exceptions

NSF's override and exception model enables:

• Safe governance agility in real-world risk escalation

• Formal institutional logic under emergency or failed-model conditions

• Verifiability of every exception path—no hidden levers or shadow execution

• Machine-readability of fallback policies and override triggers

This transforms exceptions from informal political responses into signed, traceable, simulation-aware, clause-bound logic—all under DAO oversight.
