Every mark
defends its
chain of custody

Dossier handles interface work the way a court handles evidence: cold paper fields, exact ledgers, redaction as structure, and a single point of verified light.

Procedure

From intake to seal

Nothing enters the desk without a custody event. Every step writes a timestamp, an actor, and a hash — so the record can stand on its own.

01INTAKE

Scan & hash

The exhibit is scanned to a frost-white sheet and sealed under SHA-256 and BLAKE3 at the moment of arrival.

02REDACT

Apply masses

Black redaction bars crop across the real content as structural masses — censorship that is procedural, never decorative.

03VERIFY

Confirm provenance

A single icy-blue tick marks the hash matched against the master ledger. Blue is the only color you ever have to count.

FOIA · exemption (b)(7)(C)

Redaction is the layout

Black masses outrank everything. They set the asymmetry, crop the page, and create the cold negative space that makes a sealed field feel sealed. Blue only ever confirms — it never decorates.

Verified ledger

The record holds

A chain of custody is only as good as its weakest link. Dossier keeps the count visible so you can trust it at a glance.
