+
+### NFT-RES-LIM-01: [Test Name]
+
+**Summary**: [What resource constraint this validates]
+**Traces to**: AC-[ID], RESTRICT-[ID]
+
+**Preconditions**:
+- [System running under specified constraints]
+
+**Monitoring**:
+- [What resources to monitor — memory, CPU, GPU, disk, temperature]
+
+**Duration**: [how long to run]
+**Pass criteria**: [resource stays within limit — e.g., memory < 8GB throughout]
+```
+
+---
+
+## Guidance Notes
+
+- Resource limit tests must specify monitoring duration — short bursts don't prove sustained compliance.
+- Define specific numeric limits that can be programmatically checked.
+- Include both the monitoring method and the threshold in the pass criteria.
