Description

For example, how to interpret:

  • m.room.encryption events that have been redacted
    • when you're in the room when the event is redacted
    • when you join the room after the event is redacted and so don't see the original event
  • m.room.encryption events that are "invalid"
    • missing fields
    • use an algorithm that you don't understand
  • multiple m.room.encryption events

Compare the behavior for redacted, invalid, and repeated encryption events, including the cases listed in the issue. Done means the specification explicitly defines how each case should be interpreted.
