 ## Manual publication
 
-`Deploy consumer website manually` runs only through `workflow_dispatch` on main.
-It repeats the publication tests, builds the consumer directory and verifies a
-regular-file `artifact.tar` before deploying through the existing `github-pages`
-environment. It never deploys on pull requests or pushes. Only the deploy job has

-The tar packager preserves exact declared dot paths, including security.txt and
