Backplane
State: open/active
Definition
Section titled “Definition”The coordination layer the CLI and the engine claim and record through. Git refs today.
Contrast
Section titled “Contrast”Not the corpus.
The backplane is pluggable: by default there is no server (git refs on one machine, or several peers sharing one ref authority); later, an always-on server is one more peer. The corpus itself is never behind a port.
