Select assignment-specific keyword snapshots, improve model-token recall and calendar dates, and reuse supplied originals. Keep extraction boundaries while checking compaction against the final research context.
Extract reusable literal keywords once per source revision, assign complete news packages to long-lived events, and research all event members with immutable evidence and references.
Add additive research storage, vocabulary snapshots, the two-stage workspace, isolated acceptance coverage, and a paused rollout with an initial fixed 50-news production trial.
