### The integer decoders on Vulkan GPUs, and the golden suite on RISC-V, in CI

- **`wai-ops-gpu.yml`** has a `vulkan` job on two hosts, one with an integrated GPU and one with a
  discrete and an integrated GPU, each with the software Vulkan driver too: the operator crate's
  tests (the probe, the corpus at both widths, the mutants, WGSL's integer semantics) and every
  committed vector and refusal fixture of every capability that runs a `wai-ops/1` graph, the
  `jpegai/v1` inputs included, decoded with its graphs on each adapter and held to the decode on
  the CPU. `WAI_OPS_GPU_EXPECT` names every adapter a host must offer and `WAI_OPS_GPU_REQUIRE`
  makes a missing one a failure.
- **`wai-media-riscv.yml`** builds `byte-exact-conformance` for `riscv64gc-unknown-linux-gnu`
  and runs it under a pinned user-mode emulator: every golden the x86_64 and arm64 legs hold, on a
  third instruction set, with one changed byte failing the leg.
