ND Decision Tree

Do you need speed more than exact replay?

• If no: use deterministic exact.
• If yes: continue.

Is recall critical for user-facing decisions?

• If yes: set nd.target_recall and enable witness sample or full.
• If no: use fast or balanced profile.

Is latency budget strict?

• If yes: set nd.latency_budget_ms and accept possible refusal.
• If no: use accurate profile and larger candidate caps.

Need auditability?

• Enable witness mode and keep provenance artifacts.

Recommended starting configs

• Fast: profile=fast, witness=off, budget=low.
• Balanced: profile=balanced, witness=sample.
• Accurate: profile=accurate, witness=full.
