Reviews, tickets, and audit findings interrupt both developers and data consumers.

AGENTS THAT DO REAL WORKDATAHUB HACKATHON · 2026
Track what agents knew.Recall what missing context breaks.
Nectar records the facts an agent used—and the facts that had to be absent—then traces the damage when reality changes.

Watch missing context arrive.
Nectar remembers what had to be absent, then recalls only the work contaminated when that assumption becomes false.

One decision.

Nectar writes the approved shape, owner route, verification, and evidence hash back as one node in its living DataHub trust graph.

04 / WHY IT MATTERSCatalogs tell agents what data means.
Catalogs tell agents what data means.
Nectar remembers what their decisions silently depended on.
Positive evidence and bounded absences live in the same graph, so late metadata can invalidate exactly what it contradicts.
Contaminated claims are recalled across agents while independent work remains trusted and reusable.
