US Federal Register — Final Rules (28-day)

## What this measures

The trailing-28-day count of **final rules** published in the US Federal Register — the rules that now carry the force of law. It reads as the government's regulatory *output*: how much binding rulemaking has landed in the last four weeks.

## Why it matters

A rising final-rule count precedes compliance cost, sector re-rating, and the late innings of the Regulatory Shock schema. We watch it alongside proposed rules (the pipeline) and significant rules (the high-impact subset).
