The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2018.

Read together — 25% release, 27 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$753K of Kings, written across 150 government filings.
