Test the runtime on your device.
Run deterministic scenes through native Graphite, WebGL and Skia raster, compare pixels, and inspect actual native PDF raster decisions. Results stay in this browser. Software adapters are identified separately from hardware.

Pixel and lifecycle checks
Four deterministic scenes and repeated rendering on each backend. Timing includes CPU work and queue completion; it is not a GPU timestamp measurement.
Document observability
A vector-only PDF must produce no raster-decision events. A blurred page must produce native events with page, bounds and coordinate-space information.
No qualification has run yet.
Font callback inspection
Choose a font you have permission to use. Registration and canonical glyph-path callbacks run locally; no font bytes are uploaded.
The default qualification corpus needs no font files.
Evidence
The report records adapter identity, pixel errors, native diagnostics, runtime version and workload sizes.
These checks qualify the fixed workload shown here. They do not prove complete overload parity, every font or animation input, indefinite production stability, or compliance with every document standard.
