Detailed Description
NullAdapter — the always-available no-op backend.
NullAdapter is what a library binds to when the host application has not installed a real backend. Every definition and mutation becomes a logged no-op, so a library can declare and exercise metrics unconditionally. It is stateless after construction and therefore fully thread-safe.
