The Open-Source Surface Index.

A single number for a moving target: whether the publicly accessible intelligence surface is expanding or contracting. Composite, 90-day trailing.

CURRENT · 74.2+128 OPENED−141 CLOSED
WHAT IT MEASURES

The net movement of the open surface. Sources that open: new public datasets, opened registries, released tooling, lift the index; sources that close: APIs walled, records sealed, tools deprecated lower the score.

WHY TRAILING

Single days are noise. The 90-day window is the signal.

WHY IT COMPOUNDS

The index is only meaningful because it has been logged, unbroken, from day one. It cannot be back-filled.

GLOBAL STABILITY · MODEL-ASSISTED · SOURCED
