The gate kernel of wai.quantum.circuit and wai.quantum.circuit2, written in
WGSL with unsigned 32-bit arithmetic only, is compiled here by this page's own WebGPU and run in a
worker. The adapter's arithmetic is probed against the CPU's first; the kernel is then certified
against the CPU reference on two corpora per gateset. A bit-exact member reproduces the reference's
pinned corpus digests (quantum-conformance/fabric/expected.json); every vector of the
quantum corpus must reproduce its statevector hash, and every reject file must be refused with its class.
The same adapter then runs the tile implementation (runs of gates applied tile by tile, one dispatch
per run), certified against the same digests.
