Overview

Triggers compaction at logical decision boundaries rather than only at capacity limits. This prevents late-session context bloat by compacting after meaningful milestones.

EARLY_COMPACT_RATIO =

Percentage of context threshold at which to trigger compaction on decision boundaries (lower than the default 95%).
