About

disclosure.zone is a UAP case database in which every claim carries a source tier and every case carries an openly computed evidence score.

Why this exists

There is an enormous amount of UFO material online and almost none of it distinguishes an operational document from a recollection thirty years after the fact. The result is that strong cases sink together with legends, and sceptics discard both in one gesture.

This database does one thing almost nobody does: it separates the layers. Tehran 1976 rests on an intelligence report from the period. Rendlesham rests mostly on accounts written decades later. Nimitz rests on sworn testimony but without raw data. Those differences matter more than the shape of the object.

State of the database

• 74 cases from 24 countries
• 89 claims on the ledger
• 170 sources: 74 with a verified link to the material, 40 pointing at the holding archive, 56 with neither

That breakdown is deliberately visible, and the middle column is deliberately separate. Knowing which archive holds a record is useful, but it is not the record — counting the two together is the easiest way to inflate an apparent evidence base. Every link in the registry was checked against a live source rather than guessed, and completing the rest is ongoing work.

Limits

No single global database contains every UAP case. Many national archives are incomplete, part of the British documentation from before 1967 was destroyed under routine records disposal, and many holdings were never digitised. This corpus is a selection of the cases with the highest analytical value, not a complete census.

Scores on the eight axes are expert judgements computed by an open algorithm. The algorithm is public precisely so that it is possible to disagree with it at a specific point, rather than only in general.

What will not appear here

• Social media material without provenance.
• Amplification of informants whose claims cannot be set against a document.
• Headlines in the “shocking disclosure” register.

Rigour is the product here, not the decoration. One post written for clicks destroys the only thing separating this database from a thousand other UFO sites.
