Dense Contact Stress Scene
The contact pipeline stays legible under denser stacks and crowding.

What you are seeing
Scene
A denser arrangement intended to show how the engine behaves once the easy demo cases are exceeded.
Why it matters
Stress a dense contact field to expose solver quality and contact throughput under load.
Pass condition
Scene should remain coherent without immediate blow-up or unreadable contact instability.
Proof views
Use Public proof for the clean buyer-facing read, Event focus for adaptive slowdowns around the key moment, and Debug proof for contact cues, overlays, frame numbers, and proof-lane instrumentation.

Systems exercised
- contact islanding
- solver workload
- collision throughput
Known limitations
- Not a substitute for the dedicated benchmark suite.
Recommended context
Use this right before a benchmark discussion to connect visuals with performance claims.
Determinism status
- same build: expected
- cross-run: reference-run suitable
- cross-platform: validate separately
- snapshot / restore: broader toolchain supported
