name: wai-quantum OpenCL member

# The fabric's OpenCL member: the gate kernel in OpenCL C, built at run time by
# each device's own compiler and certified bit-exact against the CPU
# reference's pinned corpus digests.
#
# - opencl-hw, on each host with OpenCL devices (jetson-hub: the vendors'
#   runtimes for its CPU, its discrete GPU and its integrated GPU; thor: PoCL
#   for its CPU and, through CUDA, its GPU): the devices its matrix entry
#   declares, each by a key that carries the device's vendor id
#   (opencl-<kind>-<vendor id, hex>). The device
#   tests must find exactly the declared devices, agree with the CPU on the
#   arithmetic probe and on random states (out-of-range runs included),
#   reproduce all four pinned certificates on each device (two gatesets,
#   random-v1 and fabric-v1), and catch every kernel mutant on each; and the
#   dense f64 state vector, run resident (the state on the device for the
#   whole run), must come back with the CPU's bits on each, on its pinned
#   corpus and on random circuits, its wider kernels certified on their own
#   corpus or said not to be (a member whose wider kernels did not certify
#   runs gates on up to three qubits at once).
# - opencl-amd (framework-128gb): the same on its integrated GPU, through the
#   GPU vendor's OpenCL platform, the state vector included.
# - opencl-macos (the macOS runner): the same on the platform's GPU, through its
#   OpenCL 1.2; that GPU has no binary64, so the state vector is refused there,
#   with the reason.
# - opencl-absent (a container with no OpenCL): the same build finds no member
#   and says why, rather than failing; the device tests run over no member with
#   the declaration `none`.
