name: wai-quantum HIP member

# The fabric's HIP member: the CUDA member's kernel text, unchanged, compiled at
# run time by HIP's runtime compiler for each device's own architecture and
# certified bit-exact against the CPU reference's pinned corpus digests.
#
# - hip-hw (framework-128gb, its integrated GPU): the device tests must find
#   exactly the declared device, agree with the CPU on the arithmetic probe and
#   on random states (out-of-range runs included), reproduce all four pinned
#   certificates (two gatesets, random-v1 and fabric-v1), and catch every
#   kernel mutant; and the dense f64 state vector must come back with the CPU's
#   bits on its pinned corpus and at 16 and 20 qubits, every state-vector
#   mutant caught.
# - hip-absent (a container with no GPU and no HIP libraries): the same build
#   finds no member and says why, rather than failing; the device tests run over
#   no member with the declaration `none`.
