Rudder

Adding the technique/rule/directive that I imported.
Archive contains:

As of 8.0, the situation is at the same time better and worse:

- I tried to import the provided archive as explained,
- I didn't got any error (generation, etc). But the technique is not available at all, the technique editor refuse to display it, and the technique was no translated into a YAML technique

So we have the same root problem I think - technique are not regenerated, so no migration for the json.
But now, we don't even see the technique in editor, so no workaround anymore.
But at least now, generation doesn't break (and I can even delete directive and technique marked as being in error)
