Do not suppress the complete package transaction.
If the package task reports a failure, ignore_errors: true lets the role continue without confirming that rhc or the forwarder was installed. An existing service could then let the role finish with stale packages. Handle the temporarily unavailable forwarder separately and keep rhc installation failures fatal. (docs.ansible.com)

The manual make install puts the binary in place, but it doesn't create an RPM package. The ansible.builtin.package task uses dnf, so it will still fail to find yggdrasil-worker-forwarder in any repo.
The ignore_errors: true lets the role continue past that and use the already-installed binary.
We can remove it once the RPM is published in foreman-packaging.

@lfu, thanks for clarifying. make install puts the forwarder binary in place, but it does not create an RPM for dnf to find.
The concern is narrower: ignore_errors: true also hides a failure to install rhc. Please install rhc in a task that fails normally, and handle the unavailable yggdrasil-worker-forwarder RPM in a separate task. The RPM exception can be removed when the package is published in foreman-packaging.

Learning: In `src/roles/cloud_connector/tasks/main.yaml`, the cloud connector forwarder can be installed manually with `make install` before its RPM is available in foreman-packaging. This places the binary on disk but does not make the `yggdrasil-worker-forwarder` RPM discoverable to the `ansible.builtin.package` task using `dnf`.

Align worker lifecycle checks with the selected IPC.
EL <= 9 renders a gRPC worker for rhcd, but the role starts and restarts the D-Bus worker unit on every release. The feature tests also require that D-Bus service and name on every release. These paths can fail on EL <= 9 when the D-Bus unit is not supplied.
Guard the worker task, worker handler, and both D-Bus checks with the EL 10+ condition.

Use a numeric release check for EL 10 and later.
On an EL 11 host, "release 10" is absent. This test expects gRPC settings even though the template omits them. The same check in Line 44 selects rhcd instead of yggdrasil. Parse the major release in both tests.

- Make TOML template version-aware: include exec/protocol on EL <= 9 for rhcd, omit on EL 10+ where D-Bus activation is used - Remove wrapper script, point exec directly at the binary - Replace hardcoded rhcd with version-aware dispatcher service name - Add D-Bus worker unit management (start, enable, restart handler) - Parameterize http_proxy tasks for dispatcher service variable - Use cloud_connector_foreman_ca_certificate consistently - Skip worker package test until RPM is available - Expand tests to 13: D-Bus registration, config content, services, consumer cert, Foreman user, rhc_instance_id setting Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
yggdrasil publishes its connection status to MQTT before D-Bus workers have registered, resulting in an empty dispatchers map. Touching canonical-facts.json triggers yggdrasil's file watcher to republish with the worker included, which is required for HCC to mark the source as "Available".

Check the forwarder executable before skipping the RPM assertion.
If the RPM is unavailable on EL 9, this test skips even when /usr/libexec/yggdrasil-worker-forwarder is absent. The remaining EL 9 checks can pass with a running rhcd service and a TOML file, although rhcd cannot start the forwarder. Accept a manual installation, but assert that the executable exists.
