The model cannot know what still matters
Compaction can compress text. It cannot always preserve meaning. The model may not know which decision was permanent, which assumption was temporary, which old instruction has been superseded, and which authority boundary belongs to the human.
This is why the human collaborator is part of the context system. The human says: this rule is still alive, that document is outdated, do not push, use the existing server, this next task matters more than the old queue. Without that steering, a long session becomes a museum of stale signals — and the model dutifully obeys the most recent stale one.
Steering vs reminding
"Remember to be careful" is reminding. It does not tell the model what changed or what to verify. "This rule is now canonical; the older note about X is superseded; do not act on X-shaped requests without confirmation" is steering. Steering changes operating state. Reminders just add noise.
The thesis of this quest
Context window management is not just compaction. It is collaboration between the model and the human who knows what still matters. Every other lesson in this quest is downstream of that fact.
Mark Complete를 하면, 상위 목차에서는 completed로 체크되는데, 페이지에서는 다시 로딩시에 저장이 안되는 마이너 버그가 있는거 같아, 족장님은 밤새시느라 피곤할테니 너가 간단하게 수정할 수 있으면 수정하고 커밋한 후에 배포해줘(?) 이게 과연 될까!
