Summary

• complete the authored island surface and hero-landmark quality pass across all 41 islands
• fix the severe camera-feel regression by bounding runtime materials to palette families, restoring display-synchronized presentation, clearing inactive mouse history, and removing oversized hero camera blockers
• add material, frame-time, slow-frame, continuity, and base-vs-candidate regression gates
• update the evaluation contract and project status with measured root-cause evidence

Root cause

The surface pass increased live materials from 100 to 244, raising full-content average frame time from 9.77 ms to 15.63 ms. Palette-family reuse restores the same 1.23M-triangle scene to 116 materials and about 8.6 ms. An attempted AutoNoVsync mitigation was also rejected after measuring worse 14-16 ms pacing on the validated Mac; the play window now explicitly uses display-synchronized presentation.

Verification

• cargo fmt --check
• cargo check --all-targets
• cargo clippy --all-targets --all-features -- -D warnings
• cargo test --all-targets --all-features
• camera continuity gate: 13/13 scenarios, including fault-injected snap rejection
• development performance gate: debug 8.6400 ms average, release 8.6304 ms average, 116 materials, 1,228,832 triangles
• world content gate: all 41 islands and 123 hero views passed
