Motivation
Test out a bunch of scenarios with the worker, included the problem described in #11928
Context
This is in many ways the culmination of my JSON work --- we now can unit test the "heart" of Nix (
Worker, building/substitution) and we do so in a failure implementation agnostic way, since other things can read the JSON.Add 👍 to pull requests you find important.
The Nix maintainer team uses a GitHub project board to schedule and track reviews.
