| audit event | Data shape | An append-only record of who did what to which object and when, written for later reconstruction rather than for debugging. | 2026-09-06 |
| cursor pagination | Transport | Paging through a collection with an opaque position marker rather than a numeric offset, so that concurrent writes do not cause rows to be skipped or repeated. | 2026-09-06 |

| SAML single sign-on | Identity | A browser-mediated exchange in which an identity provider issues a signed statement about a user and the application accepts it in place of its own login. | 2026-09-06 |
| SCIM provisioning | Identity | A published HTTP schema, RFC 7644, by which an identity provider creates, updates, deactivates and groups accounts in an application without anyone administering them by hand. | 2026-09-06 |
| tenant isolation | Operations | The guarantee that one customer's data in a shared system cannot be read, written or inferred by another, enforced at the query layer rather than in application logic. | 2026-09-06 |
