Research direction

Open the linked end-to-end encryption implementation guide and read the “Encrypting an event with Olm” section, especially point 2. Compare its session-conflict advice with the specification, then update the guide to describe using the last successful session and verify that the published wording no longer recommends ASCII ordering.
