What you will build
A bounded flow that answers from one approved source set and returns intentional silence outside that evidence.
Inputs and ownership
- One narrow business question
- An approved source owner
- A defined user or application role
Blueprint
This illustrates the governed fields to define during onboarding; it is not a public production API contract.
{
"knowledge_unit": "support-policy",
"source_version": "2026-08",
"allowed_scope": ["support-agent"],
"insufficient_evidence": "abstain",
"audit": { "retain_claim_basis": true }
}Build it step by step
- 01
Choose the bounded use case
Write the question, the permitted user and the decision that the answer may influence.
- 02
Register the source identity
Assign an owner, version, effective date and retirement rule before the material enters inference.
- 03
Create the VARVE boundary
Separate payload, scope policy and audit anchor so content and control do not collapse into one object.
- 04
Set intentional silence
Define what counts as insufficient evidence and the exact behavior expected when that condition is met.
- 05
Verify the trail
Run supported and unsupported prompts, then inspect the basis retained for every material claim.
Prove the governed path
- The permitted path produces an answer from approved evidence.
- An unsupported request returns an explicit governed outcome.
- Every material claim resolves to a known knowledge unit.
- The decision can be rerun after a source version changes.
