Inspect the audit and execution records available for the operation in question, including actor context, timestamps and results. Coverage, retention and privileged access must be verified. An append-only application design is not a promise that every possible state change is captured or that a database administrator cannot alter storage. Read more.

Compare subsequent readings and programme evidence with the earlier period, checking scope, definition changes and missing inputs. Impact review can record what changed and what was undertaken. A before-and-after difference alone does not establish that the action caused the change. Read more.

Client checks guide what the interface presents; server checks enforce authorised operations. HEPO uses layered permission concepts, but matching behaviour across each path must be demonstrated. A hidden button is not a substitute for a server-side check. Read more.

The data model separates platform, business records, definitions, audit, analytics and framework concerns. Logical schema separation alone does not prove production tenant isolation. Verify the tenant selection, access and storage arrangements of the actual deployment. Read more.

Some background or integration work may require a service identity. Separate that execution identity from the person requesting or approving the business action. Review its scope, credential management and available audit evidence. Read more.

Agree data access, operational credentials, licensing, support and handover terms in advance. Customer-controlled deployment helps keep the material within the agreed environment, but uninterrupted operation and transition arrangements need an explicit plan. Read more.
