[frontier] Treating context management as fitting tokens instead of preserving true task state

Externalize durable constraints, decisions, and unresolved issues to structured out-of-context state. Use the context window only for the current working set; retrieve or re-inject durable state at each step.

Journey Context:
Anthropic's Applied AI team frames context engineering as curating the smallest high-signal token set. The deeper insight from long-horizon agent research is that every summarization, compaction, or retrieval operation is a state-estimation step that can silently drop constraints. The common error is maximizing context window usage. The right call is to keep architectural decisions, safety constraints, and open questions in a durable structured store outside the window, then load what the current step needs.
