 [Mimir](https://github.com/GameCult/Mimir) appeared as an OBS streaming bridge and a research/calibration harness: the one in the room with its ear against the pipe, insisting that a live signal is not the same thing as a diagram of a signal.

 Odin is the late arrival who does not bring an opinion so much as a table with enough seats. Mimir brings signal. AquaSynth brings voice. Aquarium brings a place for bodies to be seen. Odin's job is to let them find each other without confiscating their identities.
