Endpoints have an optimized code path, as they are by far the most frequently updated resource - in a steady cluster, this will often be the *only* change, caused by scale up/down.

As a result, they do not go through `PushContext`, and changes do not trigger a `PushContext` recomputation. Instead, the current state is incrementally computed based on events from `ServiceDiscovery`.

#### Conclusion

Overall, the high level config ingestion flow:

All Possible Errors
- invalid lifecycle phase (maybe same as bad CLI param, though you were talking about embedder too)
- <module> specified is not found
- malformed settings
- malformed POM
- local repository not writable
- remote repositories not available
- artifact metadata missing
- extension metadata missing
- extension artifact missing
- artifact metadata retrieval problem
- version range violation
