Context Prioritization Rubric Builder Prompt

Build a rubric for deciding what to keep in a context window when it overflows.
Score each candidate chunk on: recency, relevance-to-current-step, uniqueness (not duplicated elsewhere), and authority (source trust).
Provide a formula combining them into a single keep-score. Then state the threshold below which a chunk is dropped, and what happens to dropped chunks (summarize? evict? archive?).
