GROB's multi-agent architecture captured Census identifiers on 9 September from public traces alone, later resolved by public revision records to specific 16–17 June Census requests
GROB is a multi-agent architecture that performs controlled, read-only collection of public Internet traces when privileged telemetry is unavailable and preserves observations for later resolution; in a frozen September 2026 corpus, Census identifiers captured on 9 September were later resolved by public revision records to specific read-only Census requests from 16–17 June, while other traces showed links of varying strength and public traces alone did not establish organizational attribution.
