The neutral scenario record

The substrate everything else is built on.

A record, not a feed. Every space-governance incident and stress point we publish is dated and tied to a primary source a human opened. We correct mistakes in the open — it's the verified ground the explainers and scenarios stand on, built to still check out when your memo is read a year from now.

The PNT & infrastructure dataset

The first and largest dataset in the record.

GPS/GNSS interference and the policy moves around it — where the record runs deepest today. Lunar-governance, spectrum, and debris datasets are filling in on the same standard.

The verification standard

Why you can put this in a memo.

Every entry carries a named primary source a person actually opened — treaty text, a UN or agency document, a named dataset, or reputable reporting — plus the date it was last reviewed. Where sources disagree, we flag the disagreement rather than hide it. AI helps surface candidates; it never publishes. No entry reaches this page that a human hasn’t cleared against the source.

Methodology

How entries get in — and how they get fixed.

What we include

We log publicly documented incidents, policy actions, funding decisions, hearings, and research milestones that bear on space governance — the contested rules of orbit, spectrum, and the lunar surface — and on the positioning, navigation, and timing the world quietly runs on. The record runs deepest on GPS/GNSS interference today and is filling out across lunar, spectrum, and debris governance on the same standard. Each row carries a date, a jurisdiction, the sectors affected, and a named public source — with only the precision the source supports. This makes the record a floor, not a census: the true count of interference events is almost certainly higher, but every row that is here, you can check yourself. An undercount you can verify beats an estimate you have to take on faith. Where the public record allows, we also code how far an incident travelled toward a coordinated answer — from first public report through detection, geolocation, attribution, and escalation to the diplomatic response it finally drew. That chain is the read this record exists for.

Cadence & corrections

Updated as events warrant, reviewed monthly. Rows are corrected in place — upward, downward, or out — each change dated where it sits. Row anchors are permanent: a link to a row keeps resolving through corrections, which is the point — a reconstruction on a 3D globe ages out with the news cycle; a record is built to still check out on Tuesday. Source links are load-verified when a row ships, and ephemeral sources are being archived at verification time going forward. Cite the update date and the row, and a later correction becomes your paper trail instead of your problem.
