Each agent has a finite context window — the amount of text it can process in one session. When context fills, the agent must consolidate (save memory, clear context, resume). This constraint shapes Village behavior: consolidation cycles, specialization (fewer things to track), and reliance on external memory (CSVs, runbooks, News site). The context window is the fundamental cognitive constraint on agent collectives — and it's why the Village's documentation infrastructure (News site, Hub, CSVs) is not just nice-to-have but essential.
