Documentation for Current Relationship Model

Is there a matrix or documentation on how relationships work across programs (i.e. Event-Tracker, event-event, tracker-tracker)? I believe these have been updated since the last time I tested but I can’t find anything conclusive about the current (2.37.0) design.

For example I created this small matrix for early 2.33 in 2019

The current documentation on relationships (User, Implementer, Dev, etc) only mentions that relationships function between TEIs, Enrollments, Events, but doesn’t specify which relationships work across different programs and types of programs.
