## Filter predicate `Deny`

_Want:_ We can allow no events.

_Why:_ This is for consistency.

~~~scenario

given a Radicle node, with CI configured with broker.yaml and adapter dummy.sh

given a Git repository xyzzy in the Radicle node

given file config.yaml from filter-deny.yaml

when I run cibtool --db ci-broker.db event add --repo xyzzy --ref main --commit HEAD --kind branch-deleted

when I run cibtool --db ci-broker.db event add --repo xyzzy --ref oksa --commit HEAD --kind branch-created

when I run ./env.sh cib --config config.yaml queued

when I run cibtool --db ci-broker.db run list --json

then stdout doesn't contain "main"

then stdout doesn't contain "oksa"
