Discovery: Plugin system for platform-specific introspection #112
Description
Summary
To reach "full" discovery, we may need platform-specific introspection, especially to map ROS Node to Process and possibly other runtime contexts.
This mapping is important for some diagnostic operations, but it depends heavily on deployment:
- Plain processes from launch
- Composable nodes in a single process
- Containers
- systemd
- A custom process manager
Core discovery should not hard-code assumptions for all environments.
Proposed solution (optional)
- Define a small plugin interface for runtime introspection providers.
- Provide a default provider that works in the simplest environments.
- Allow additional providers for:
- systemd based deployments
- container based deployments
- custom process managers
- Integrate plugin results into the merge pipeline as enrichment data.
