DTL Taxonomy
Open sourceThe open claim taxonomy and verdict schema. The vocabulary controls and evidence are expressed in.
What it checks
- Claim classification schema
- Verdict schema
- Interoperable verdict format
What it does not check
- It is a schema, not a checker. It defines the shape of an answer.
Where it sits
DCLA
DTL Taxonomy runs inside DCLA
Deterministic Control Lineage Architecture
The governing rules changed. What does that affect?
DCLA tracks changes to regulations, policies, controls and operating requirements, then identifies the systems, decisions, evidence and previous approvals that may need reassessment. Affected work is held rather than allowed to continue on a superseded rule.

Evidence
Every verdict leaves a record
| Property | Behaviour |
|---|---|
| Determinism | The same input produces the same verdict. A result that does not reproduce is treated as a defect. |
| Signing | Verdicts are Ed25519 signed and anchored in a tamper-evident chain. |
| Replay | A sealed pack can be re-run later to detect verification drift. |
| Availability | Fail-closed. If this gate cannot be reached, the result is recorded as unavailable, never as a pass. |
| Independence | A third party can verify a pack without our source code and without contacting us. |
Run it against your own cases
The audit protocol is public. You do not need our permission, our source or our involvement to test a gate and publish what you find.
