Pembrolizumab / Keytruda · NSCLC — unattended agent keeps a trust-scored graph so LLM answers stay checkable.
Same mixed question includes KEYNOTE-888, which is not in the graph. Bare may invent; grounded cites openable edge IDs; strict leaves that clause empty. Not who writes better — who does not invent what the graph lacks.
Before / after from live /graph and first-build /changes digest (what / why / ids).
One-click: agent notifies → you consent → session binds to the latest graph. Grounded or Strict. No download.
