The harness has its canon. Its open questions have answers.

The harness discipline now has a canonical text: guides steer the agent before it writes, sensors correct it after, and a steering loop improves both when issues repeat. This post adopts that vocabulary and takes the next step: the canon's own open questions — how do guides and sensors stay coherent as the harness grows, how do you evaluate harness coverage, what does a silent tool mean — are exactly the questions a typed, witnessed subject answers. A check that does not declare what it looked at is a harness lying by omission; a sensor whose verdict is signed is one you can audit. The harness runs the agent. The subject is what the harness queries.
