Scope and Validation Boundary

This lexicon defines the NovaFuse vocabulary for Executable Reference Implementations, governed release, deterministic decision artifacts, evidence, replay, and verification.

Validation metrics in this document are conformance expectations inside a declared ERI boundary and test scope. They are not universal production guarantees. A benchmark of Required means the property must be demonstrated by the applicable conformance test. No observed occurrence means the prohibited condition must not appear in that declared test scope.

ERI is an executable reference surface. It does not convert a bounded test result into a claim about every production environment.

Letter W defines how discrete units of work enter an ERI and how their execution is recorded.

W

Workload Execution Event

ERI Definition: Workload Execution Event ≡ Observable Work Progress Marker ≡ Execution Activity Record

🔑 Workload Execution Event Has 3 Critical Aspects

🧪 Measurement & Validation Tools

• Event emission checks
• Ordering verification
• Event record persistence tests

📊 Validation Metrics

🧬 Example Applications

✨ Key Insight:

If execution leaves no events, it cannot be governed.

W

ERI Definition: Workload Submission ≡ Introduction of Work Unit ≡ Execution Request Initiation

🔑 Workload Submission Has 3 Critical Aspects

🧪 Measurement & Validation Tools

• Submission record creation
• Duplicate submission detection
• Submission-to-execution correlation

📊 Validation Metrics

🧬 Example Applications

✨ Key Insight:

Governance begins at submission, not execution.
