No rank is demonstrated. Intervals overlap.
Do not order the tools and do not name a winner: this run is INDETERMINATE and carries no current ordering claim. Report the status and the observation date.

Limits of this comparison
- Population limited to employer-published emails: absolute rates are optimistic bounds; tool-to-tool comparison remains valid (same frozen set for all).
- Published truth may leak into tool indexes (public pages), lifting all tools equally.
- Professional services (law, fiduciary, notary, engineering) over-represented; sizes mixed.
- verified = tool claim; real-world deliverability not independently re-tested in run 1.
- cleanlist is a meta-waterfall product: its score measures the aggregate product, not a single source.
- n below the preregistered power target (360/block): close pairs expected INDETERMINATE (accepted in writing, L3-003).
- Costs are credit estimates at public per-credit prices (prices.json); subscriptions prorated there.
- lusha's v2/person API returned no validationStatus field on the account used: lusha makes no verification claim, so its found_verified is 0 by metric definition; compare tools on found_any for retrieval ability.
- Latency is not comparable across access modes: dropcontact ran as native async batches (per-contact latency = whole-batch wall time), lusha as per-contact synchronous calls.
- Precision insufficient under the frozen protocol: no rank published.
