Dataset. A version and a hash. Loading lines on the page are not a checklist of controls. - Step 02
Build the universe
Point-in-time membership is built from the registry, not from a live screen.
Constituent membership is reconstructed as of the date of the test, keeping delisted names in the sample.

Historical exits retained
Delisted and acquired names remain in prior windows to prevent survivorship bias.
