llm-agent-vs-deterministic-script-decision-hierarchy

Established a formal protocol: cron script > hook > human-directed session > autonomous LLM agent. The Archivist nightly synthesis agent was replaced by a 2-second cron script (vault-hot-cache.sh) at zero API cost — the real-time cascade engine already handled 95% of compounding value. Never deploy an LLM agent for a job a deterministic script can do; highest-grade outcomes at lowest cost.
