# Continuous integration for wl-webrtc.
#
# Triggered on push/PR to master. Runs the full quality gate that the recent
# audit baselined:
#   - clippy: 0 errors (undocumented_unsafe_blocks is deny in Cargo.toml; other
#     warnings are advisory for now).
#   - build --release: integration tests in tests/integration_test.rs shell out
#     to target/release/wl-webrtc, so the release binary must exist before tests
#     run.
#   - test --release: 79 unit + 3 integration; the 1 hardware-ignored test
#     stays ignored in CI (needs Wayland session + VAAPI GPU).
#   - cargo audit: separate job so a RUSTSEC advisory fails the build without
#     conflating with compile errors.
#
# The job pins Linux only — the project is Wayland/VAAPI-specific and has no
# macOS/Windows story. Oracle audit 2026-06-28 P2 plan.
