Week 3 Task 2 - Texture Switcher

Objective

Test edge cases for the Texture Variant Switcher, focusing on persistence, resolution limits, and builder transparency.

Audit Test Cases & Results

Multiple Texture Swap: [PASS] Stable for low-resolution assets.
Revert to Original: [PASS] Default state restores correctly.
Texture Size/Ratio: [FAIL] Silent failure for assets > 5MB. No error feedback.
State Persistence: [PASS] Successful uploads persist reliably.
Builder Clarity: [FAIL] Asset pipeline feedback is insufficient (No progress/error UI).

Observations

Missing Primitive: Native Asset Validator (checks for file size/format before attempting upload).
Workaround: Manually downscale all high-res textures (4K/8K) to 2K (under 5MB) before uploading.
Minimum Support Needed: An "Upload Error" toast notification for file size limits.

Classification

Asset Pipeline Limitation: Critical (Silent failures).
Runtime Issue: None.
Editor UX: Confusing during upload failures.
Schema / Data Model: Stable.

Reliability Verdict

PARTIALLY RELIABLE

Product Lens

Is this pattern useful for real customers?: Yes, but the 5MB limit will frustrate professional texture artists.
What kind of customer use case does this support?: Web-optimized configurators where 1K/2K textures are the goal.
Does Thob feel strong enough for this use case?: Partial. Stability is high, but discovery and asset handling are "fragile."
What would improve the experience?: An explicit "Optimization Guide" or built-in texture compressor.

Recommendation

Thob needs to handle asset rejection gracefully. A "Silent Fail" is the worst possible UX. Implementing an error handler for the asset library should be a priority for Week 3.
