# Per-PR gate for dasVulkan changes, paths-filtered so PRs that never touch the
# module pay nothing. Carries the two cheap correctness gates: the generator
# skip-ratchet (an emitter change must not silently shrink the bound surface)
# and the module-wide lint. The full render suite is nightly_vulkan.yml.
