AI agents that write recurring business reports start from zero every week, so they can't say "third week in a row" or "the fix you tried didn't work." Longview gives an analyst agent persistent memory: each week it forms hypotheses about why revenue moved, tests each against live data in MongoDB Atlas, and reinforces, contradicts, or supersedes its beliefs. A self-improvement loop scores every run on hard metrics (no LLM in the scoring), reflects on its own failures and Raindrop telemetry, and writes a new playbook version (rules, guardrails, parameters), accepted only if it scores strictly higher.
