Comparing harnesses

This page has moved. The properties worth comparing, the projects that hold them today, and this repository’s own gaps are in the dated field scan, which is re-checked on a schedule and replaced rather than amended.

The one line worth keeping from the old version: send a comparison, or a counter-example, as an Idea issue. The point of publishing the harness is to find out which of its claims hold up outside one person’s workflow.
