Changelog and versions
Current model versions and the change policy.
Current versions
| Surface | Version |
|---|---|
| API envelope | v1 (field names frozen) |
| Score model | identity_score_v1 |
| Decision model | decision_v0.4.1 |
| Stats endpoint | stats_v0.1 |
Every decision response carries version, scoreModelVersion and decisionModelVersion so you can pin behavior. Receipts keep the model versions they were minted with.
Change policy
Additive changes (new fields, new codes) can land in v1 without notice. Breaking changes go to v2. Reason and warning code lists can grow; treat unknown codes as informational rather than failing.
