Comment (by cypherpunks):

 Replying to [ticket:16599 virgilgriffith]:
 > If two families have exactly the same oldest "first_seen" field, the
 families are assigned UUIDs based on asciibetical order of the oldest
 relay's fingerprint.

 Multiple families can have the same oldest relay (same first_seen + same
 fingerprint) as one relay might be part of multiple families (depending on
 the point of view).


 > This UUID number will be invariant under relays leaving / being added to
 the family.

 Does that mean the following scenario will link all families over time and
 the family id will never change?
 {{{
 T0: a b c
       b c d
         c d e
 T3:       d e f
 }}}
 (a, b, c, d, e, f are all relays, 'a' is the oldest; time is progressing
 vertically from top to bottom)


 > Finally, upon receiving a request with a specific relay's fingerprint,
 Onionoo would return:
 >
 >  1. The symmetric family, a.k.a. the "effective family" of that relay.
 If there is none returns an empty list.
 >  1. The UUID (a positive integer) of that effective family.

 A relay might be part of multiple families, so it would have to return 0
 to N family IDs?
