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.
