Case file
Subjects, links between them, an append-only diary, tasks and the status history, in one place.
DENDAT SERVANT is where investigators run cases: subjects, the case diary, tasks, exhibits with an unbroken chain of custody, and requests for data from other registers. A request is drafted by the investigator, endorsed by a supervisor above them, and decided by the data owner, who releases only what they approve, for a fixed period. Every view is logged.
The licensing register (DVLA) is the first connected source. It never opens its database; it answers a signed request, cut down to exactly what its data officer approved.
You read a case because you are on it, or you command the unit that owns it. Restricted cases open only to commanders above them. Sealed cases open only to their members.
Subjects, links between them, an append-only diary, tasks and the status history, in one place.
Units nest. Endorsement, closure and exhibit disposal follow the tree, and are refused to the person who asked.
Opening a case, viewing an exhibit, running a search: each one is a logged event an auditor can read.
Physical items and digital files get an exhibit number and a custody record from the moment they are logged: who held them, where, and when they moved. Digital files are fingerprinted with SHA-256 and can be re-verified at any time.
Plates, chassis numbers, ID numbers, phones and accounts are matched across the agency's cases and against released register data. Matches in cases you cannot see are reported without their contents, and a sealed case's lead is told quietly instead.
