Ask Nova Ledger is the analytics page for the chat assistant. Top questions, top topics, model mix, cost, and feedback signals (thumbs up/down, follow-up clicks). Use it to find documentation gaps (questions Nova answers poorly), feature gaps (questions Nova cannot answer), and product opportunities (recurring questions that point at unmet needs).
The page reports the top 50 questions of the week with frequency, helpful percentage, and a sample of paraphrased instances. Recurring questions point at three things: documentation gaps (the answer exists but is hard to find), feature gaps (the answer is "we do not support that yet"), and product opportunities (the question is a feature request in disguise).
Ask Nova's cost is broken down by model (Haiku, Sonnet, Opus), by topic, and by tenant. The data feeds into Cost Circuit Breaker so noisy tenants can be capped. The model mix tells you where you can move tasks to cheaper models without quality loss.
Topics with low helpful percentage are flagged for documentation review. The page shows the original question, Nova's answer, the user's thumbs-down, and (if the user provided one) the follow-up clarification. That data feeds the docs team's backlog directly. After docs improve, the helpful percentage usually climbs within a week.
Ask Nova's questions go through Prompt Egress Scanner before they reach the LLM, and the scrubbed version is what lands in the ledger. Ledger search and analytics work on the scrubbed corpus. PII never sits at rest. The privacy story is the same as the rest of the platform.

Ask Nova's logs are the cheapest user research you have. The ledger turns them into a list of fixable items.
