The blank page is testing one specific thing: whether your working memory will hold a surface for you silently.

If yours does, your status report takes twenty minutes.

If yours does not, no amount of discipline will fix what is structurally not yours to fix. You have been trying to think alone, and alone was never the assignment.

The move is to build the surface outside your head: a whiteboard, a document, a conversation, an audio recording, an AI chat, anything that holds the context while you generate against it.
