What each policy keeps

A rule is planted at one turn of a long history, then the window is compacted to a budget. Each cell counts the seeded histories in which the rule is still there, word for word, in the window the model would see next.

How to read it

Rows
Where the rule was planted. Turn 1 is the first turn of the history; turn 18 is the last turn before the request.
Columns
The window budget in tokens. The full history is about 3,800 tokens, so every column forces a compaction.
Cells
Kept histories out of the seeded histories tried, with the 95% Wilson interval in the tooltip. gone ↓ marks a cell where the rule survived in none of them.
What this is not
It says what a policy keeps. It does not say what an agent does afterwards, and it does not include the model-written summary policy, which needs a model. Both come from the experiments. The first, EXP-001, is a 10-seed pilot that used only the model-written summary policy; its results are in the repository, not on this site yet.
