-# Task 1 Report
+# Integrity Audit Report: Week 3 Task 1 - Material Variants
+
+## Objective
+Stress test the Material Variant Switcher pattern to verify state integrity, object isolation, and instance management under high-frequency interaction.
+
+## Audit Test Cases & Results
+- **High-Frequency Switching**: [PASS] Repeated switching between **3 variants (Red, Blue, Yellow)** over 20+ cycles remained stable.
+- **State Predictability**: [PASS] Correct visual state always matched the UI selection.
+- **Object Isolation**: [PASS] Mutations to Object A did not leak to Object B.
+- **Instance Management**: [PASS] No unintentional material sharing observed.
+
+## Observations
+- **Isolation**: Variants are perfectly isolated per mesh node.
+- **State Model**: The state model is highly predictable; the builder successfully maintains the "Truth" of the selected variant.
+- **UI Match**: The UI and 3D viewport remained in sync, although minor visual latency was noted during sub-200ms click speeds.
+
+## Classification
+- **Component Limitation**: None.
+- **Runtime Issue**: Minor (Console binding warnings).
+- **Editor UX**: Reliable.
+- **Schema / Data Model**: Robust.
+
+## Reliability Verdict
+**RELIABLE**
+
+---
+
+## Product Lens
+- **Is this pattern useful for real customers?**: Yes. It is the most stable interaction pattern in the builder.
+- **What kind of customer use case does this support?**: Professional product configurators requiring high-speed material swaps.
+- **Does Thob feel strong enough for this use case?**: Yes. This is a core Thob strength.
+- **What would improve the experience?**: Reducing background console noise to provide a "cleaner" developer audit.
+
+## Recommendation
+This pattern should be the benchmark for all other Thob interactions. It is the most stable and reliable way to manage 3D state in the platform today.
