Assurance input
Verification results, provenance, evidence quality, holder binding and configured signals.
CHECKID · ASSURANCE & EVIDENCE
Identity Assurance & Evidence
Identity assurance is not just a score: the decision must be tied to method, source, scope, policy and traceable evidence.

ASSURANCE & EVIDENCE
Evidence is a service output; assurance is a policy-driven decision
Verification → provenance → policy → decision → evidence
Policy context
The relying organisation defines assurance requirements; CheckID provides policy/decision capability only where corresponding implementation evidence exists.
Decision trace
Decisions require reason/context/version where the real contract supports them; conceptual fields are not presented as API fields.
Verification Evidence Package
Service output is modelled as transaction + service + method + source + result + evidence references.
OpenID IDA
OpenID IDA is a reference for verified claims and verification metadata; a mapping is called IMPLEMENTED only with Tier-1 field evidence.
Audit boundary
Evidence supports dispute/audit/investigation, while retention and integrity mechanisms follow the actual source/contract.
EVIDENCE PACKAGE
Keep the conceptual envelope separate from the actual data contract
Do not invent fields.
| Concept | Meaning | Status |
|---|---|---|
| Service transaction | Service transaction identifier | Implementation where an actual ID field exists |
| Verification method | Method used | Implementation/reference according to contract |
| Source/provenance | Data/evidence provenance | Requires actual source |
| Result | Verification result | Contract-exact |
| Policy/version | Decision context | Only where implemented |
| Evidence references | Evidence references | Called a real field only when source-backed |
