The generated HTML and Cobertura reports no longer show unmeasured branch and function coverage as 100%. Poll and waitFor deadlines use performance.now so frozen dates cannot make them loop forever, the malformed-configuration test covers undefined again next to the empty array, compose health checks honor PORT, and the migration spec lists only what is still open.
