3. x's event_id is lexicographically less than y's 3. x's event_id is lexicographically less than y's
This is also known as a lexicographical topological sort. This is also known as a lexicographical topological sort (i.e. this is the
unique topological ordering such that for an entry x all entries after it
must either have x in their auth chain or be greater than x as defined
above). This can be implemented using Kahn's algorithm.
