Why

  • we hit codepaths where we hit a hard reconnect route and skip over the check where we make sure that the client isn't asking for a session we don't have

What changed

  • simplify ws<>uds proxy to not need to introspect the messages
  • fix the else check in the server so that we properly check clientNextSentSeq > 0 || clientNextExpectedSeq > 0 even if we just went through a hard reconnect
  • change the transparent reconnect test to actually test the right thing

Versioning

  • Breaking protocol change
  • Breaking ts/js API change

other test "reconnecting before grace period ends should leave session intact" should cover this
