LIVE ENDPOINT METADATA

Multi-engine metasearch. One query fanned out across 2-3 search engines (Brave, Yahoo, Yandex) with results deduplicated by URL and merged by reciprocal-rank fusion — consensus ranking across engines instead of one engine's bias, with per-engine rank attribution on every result.

METADATA PROVENANCE

Source catalog records are retained separately from live endpoint observations. Sonar score, uptime, and latency are advisory metrics. CDP indexing is not inferred from validation.
