EXPERIMENT RECORD

WEB-EXP-009

Dense DOM Spatial Distribution Failure Benchmark

Evidence: [E] Documented Failure · Status: Completed · Date: 2026-09-13

Failure analysis of individual DOM-node mounting under a dense spatial distribution.

Falsification / failure record: FAILURE RECORD: individual DOM nodes became a bottleneck under the tested dense spatial distribution. This result is preserved as evidence against the implementation under those conditions.

Reported result

frame_delta_ms161.01
fps6.2
jank_percent76.2

Interpretation

The reported run documents a severe browser-layout failure mode for individually mounted DOM nodes under the tested dense spatial distribution.

Limitations

  • The result describes the tested DOM implementation and workload.
  • The failure result should not be generalized to all DOM workloads.
  • This record is intentionally retained as negative evidence rather than omitted.
