install-smoke.yml

name: install-smoke

# Installs precise FROM PyPI on a clean runner (no source checkout shadowing the import) and
# exercises the published wheel. Three triggers:
#   * workflow_dispatch — on demand (override the install spec, e.g. precise==1.0.0rc1)
#   * schedule          — weekly drift canary: does `pip install precise` still work today?
#   * workflow_run      — right after a successful deploy (validates each release)
# Note: schedule/workflow_run only fire once this file is on the default branch.
