Corpus Foundation

Preamble

Corpus Foundation keeps the raw writing separate from the cleaned analysis record. It makes sure every drift claim can point back to a source, a date, a segment, and a reason.

The Record Has To Survive Inspection

A drift map is only useful if the underlying writing is clean enough to compare. The system needs stable source names, timestamps, segment boundaries, authorship, audience, extraction method, and approval status before it starts scoring anything.

Bad Labels Create Fake Movement

A phrase can look like drift because two sources were mixed, a date was wrong, a private note was compared against a public essay, or a label changed halfway through. The foundation catches those failures before they become insight-shaped noise.

The First Gate Is Refusal

The validator rejects claims that arrive without source references, dated comparison periods, confidence, and controlled dimensions. A report earns the right to describe movement only after it can show where its evidence came from.
