Research workbench

Create a date- and channel-specific research extract from the published daily series. The workbench validates the source structure, hashes the exact downloaded bytes, and builds the subset, preview, permalink, citation and manifest entirely in this browser. No question or selection leaves this device.

The verified subset will appear here.
Construct boundary. These values are channel-specific percentiles of press salience against each channel's own trailing two-year history. They are not event probabilities, severity, economic loss, forecasts, or investment advice. A content hash establishes which bytes were used; it does not by itself establish upstream source rights or make a changing URL an immutable archive. Save the source snapshot beside the generated subset, or recover a dated public vintage from the vintage panel.
