Stress Testing and Adversarial Simulations

Anticipating Failure Before It Happens — Simulation-Driven Assurance for Clause, Credential, and Governance Integrity

9.10.1 Why Adversarial Simulation Is Mandatory

NSF operates in domains where the cost of failure is systemic:

• Clause failure can trigger incorrect capital disbursement or resource allocation

• DAO misgovernance can destabilize disaster response or treaty coordination

• Credential forgery can bypass legal, financial, or jurisdictional boundaries

• AI-driven logic errors can propagate policy collapse at global scale

To prevent this, NSF integrates continuous stress testing, simulation-based attack modeling, and protocol-level adversarial validation as first-class governance functions.

9.10.2 Scope of Stress Testing Across NSF Layers

Layer	Stress Testing Focus
Clause Logic	Failure under conflicting inputs, malicious forks, simulation divergence
Credential Lifecycle	Forged issuers, stale revocations, selective disclosure leakage
DAO Governance	Quorum capture, multi-proposal conflict, simulation-bypass manipulation
Simulation Engine	Edge-case divergence, data poisoning, catastrophic forecast false positives
Enclave Execution	Side-channel fault injection, replay resistance, enclave rollback
ZK Proof Systems	Circuit-level faults, aggregation failures, privacy leaks under recursion
Metadata & Privacy	De-anonymization via pattern analysis, metadata leakage under correlation
Interop Bridges	Mismatched schema behavior, DAO state desync, delayed clause imports

9.10.3 Simulation-Defined Stress Suites

Each clause domain includes a domain-specific simulation test suite for:

• Execution path branching under parameter stress

• Forecast-trigger mismatch analysis

• Data injection of malformed or adversarial payloads

• Impact scoring via simulation delta forecasts

• Fork detection via version divergence under simulated edge cases

Test coverage is continuously validated by the SimDAO.

9.10.4 Clause Fuzzing and Path Enumeration

• Clause execution is fuzzed with randomized, malformed, and adversarial inputs

• Execution trees are mapped and hashed

• Simulation and execution outputs are compared for divergence thresholds

• Clauses with unsafe paths are quarantined or require AppealsDAO validation

---

9.10.5 Credential System Red Teaming

Stress tests target:

• Issuer compromise and role inflation

• VC replay and selective disclosure abuse

• Merkle tree invalidation or inconsistent proof chains

• Role boundary violations under credential misuse

• Long-range attack attempts on role decay and key rotation

Results are published to the CredentialDAO review layer.

---

9.10.6 DAO Simulation Against Governance Failure

DAO governance stress tests model:

• Partial quorum actor collusion

• Proposal collisions (e.g., two conflicting clause edits)

• Delegation circularity and proxy loop exhaustion

• Policy cascade simulation: how DAO misvotes propagate clause-state conflicts

• Minority exclusion and veto deadlocks

DAO policy is automatically adjusted if stress simulation exceeds stability thresholds.

---

9.10.7 Enclave and CAC Failure Modeling

Adversarial simulation includes:

• Enclave key compromise emulation

• Replay attack modeling on sealed data bundles

• Faulty enclave memory states and mid-execution tampering

• Multi-node CAC verification mismatch under async clocks

• Simulated physical and side-channel attacks

Fallback logic is validated for each failure case and anchored in CAC protocol specs.

---

9.10.8 Zero-Knowledge System Stress Cases

ZK simulation validation includes:

• Malformed proof chains

• Recursive circuit saturation

• Aggregation poisoning (bad batch proofs contaminating good ones)

• Selective disclosure reversal attacks via metadata inference

• Downgrade attacks via legacy client backdoors

All circuits are tested in proof-of-corruption simulations to verify resilience.

---

9.10.9 Institutional and Geopolitical Adversary Simulation

Global stress scenarios include:

• Jurisdictional forks (e.g., clause divergence across nations)

• Sovereign key compromise of simulation nodes

• Treaty zone sabotage via DAO vote coordination failure

• Simulation denial (e.g., refusal to process a triggering event due to conflict)

• Consensus attack across multi-zone governance coalitions

NSF models not only technical, but institutional threats, using treaty-aware simulation templates.

9.10.10 Stress Resilience as a Governance Condition

NSF enforces:

• Simulation-gated clause deployment — no clause executes without adversarial stress testing

• Simulation-scored DAO policy ratings — governance frameworks are rated by survivability metrics

• Credential class impact profiling — VCs are simulated under misuse to predefine safe fail paths

• Node reliability scoring — execution nodes are scored based on testbed fault injection outcomes

• Audit-triggered backtesting — all DAO decisions are post-facto replayed under stress simulations to audit impact resilience

NSF does not wait for failure. It simulates it, verifies resilience, and rejects any governance logic that cannot survive real-world complexity.
