The Long File
A tabletop RPG for a human World Master and human players, using AI to carry the math, tracking, state, and world-consistency so the people at the table do the imagining.
This isn’t AI as World Master. The World Master is a person. The AI is not generating story or replacing creativity. It is doing infrastructural work — the bookkeeping no one wants to do, the math that has always been awkward at a table, the consistency-checking — so the people in the room can do the parts that matter.
The on-ramp: what the game is and the “short sheet / long file” move. You play light. The system holds the depth.

Beta feedback
This is a working beta. The core documents are complete and internally audited. The AI instruction set has been tested across a few fresh AI instances and is still being refined through play. Feedback on all of it is welcome.
