Monthly system update, April 2026
What changed in the system over April: new sources, calibrations, retired feeds.
New sources added.
We added five new sources this month. Two regulatory pre-publication feeds for the Middle East. One enhanced corporate registry for a key offshore jurisdiction. Two private newsdesk channels covering banking-corridor stress in Asia. The structural register now reads from 9,400+ sources across all layers.
Calibrations.
Quarterly review of the scoring model completed mid-month. Three rule adjustments based on override patterns from the last sample. The most material change was tightening the false-positive rate on look-alike domain alerts, where the previous calibration had been producing more noise than signal.
Retired.
Two feeds retired this month. One stopped publishing in February and has not resumed. One had its quality drop below our acceptance threshold over the last two quarters. Both have been replaced by alternative reads on the same structural surface.
