The four heights

The same task, four distances: today's deadline, the next reviewer, the stuck moment, the pattern.

What’s the fastest way to fix the references so the duplicate is self-contained and I can tell Alex what changed?

Become — change the pattern

Every task here came from the work, not from a feature list — which is why the prompts name what you want done and never the button that does it. The tool changes; the work does not.
