Chicago Defender

CTL Reference Sheet · Version 1.0 · Published 2026-09-30

The Chicago Defender dossier (CTL-RD-INST-000001) is CTL's comprehensive evidence file on the institution: 34 sections, 28 relationship edges (19 Verified), and 42 claims reconciled 1:1 with the Type 04 evidence file CTL-EF-INST-000001. It refutes “single-handedly caused the Great Migration,” splits the porter-network core from the legend, and applies date harmonizations openly (“May 5, 1905 (BlackPast gives May 6)”).
