# smoke-test.sh — runtime smoke tests for the generated bindings.
#
# The compile gate proves the generated Swift type-checks. This goes further:
# it generates the tier-1 bindings, links them against the REAL C libraries via
# pkg-config, and runs hand-written swift-testing cases (smoke/*.swift) that
# invoke real GLib/GObject functionality through the wrappers and check the
# results at runtime.
#
# Usage: scripts/smoke-test.sh [--fresh]
#
# Output goes to ${TMPDIR:-/tmp}/swift-gtk-gen-smoke/tier-1 (a stable path so
# incremental swift builds stay fast between runs).
