# Fast checks always run; native builds run for code/CI changes.
# PRs test what they touch; main and nightly test everything. On a pull request the "Select
# checks" job maps the changed files to workspace packages (scripts/ci/affected.py), adds the
# packages that depend on them, and Clippy, the test archive and the test shards cover only
# those. Changes to the lockfile, root manifest, toolchain/cargo/nextest config, .github/,
# vendor/, tests/, scripts/ or any file no package owns select the whole workspace, as do
# pushes to main, the nightly run and Run workflow.
# Tests are built once and run in 4 shards. A few heavy tests (see .config/nextest.toml) are
# skipped on pull requests and run on pushes to main and nightly. The Windows jobs (D3D12 shaders
# and app startup) run on pull requests only when what they test changes (the GPU crate, the app,
# the viewport's GPU glue, the graphics dependencies, their scripts or this file); main and
# nightly always run them. Only main saves the build caches; pull requests restore them.
# Cross-compilation is opt-in through Run workflow; release builds remain in release.yml.
# Pushes to main and merge-queue groups use both pools: Clippy, the doc tests and test shards
# 1-2 run on the self-hosted runner (`self-hosted-fast`, warm build directories via
# scripts/ci/warm-target.sh), everything else on GitHub's runners. The test archive is built on
# GitHub's runners: the self-hosted machine has a newer glibc, so its binaries wouldn't start
# on ubuntu-24.04, while the archive runs there unchanged (same /home/runner/work checkout
# path). Pull requests, the nightly run and Run workflow use GitHub's runners only; the
# self-hosted runner refuses any job that isn't a push to main or a merge-queue group.
