- In short
- Production systems typically combine context strategies rather than picking one: a small stable monolithic prefix at session start, a progressive window carrying recent steps, just-in-time retrieval for content not preloaded, and compaction once early exploration accumulates. Each strategy addresses a distinct dimension of the context problem, so none alone can carry a long-running, evolving workload. Context strategy (how content enters the window) and context sizing (how much fits) are separate decisions that interact but do not determine each other.
