Validation model

Workbench validation is evidence for a defined change, environment, input, procedure, and expected result. A successful test does not establish universal compatibility, future performance, security, or acceptance outside that scope.

A reproducible validation record identifies:

1. the change and source revision;
2. the controlled test scope and prerequisites;
3. the environment and relevant configuration;
4. the procedure and expected results;
5. the observed results and retained artifacts;
6. findings, deviations, and limitations; and
7. the authorized reviewer and decision.

Testing may be risk-based and use multiple stages, but no stage name or tool implies a product-wide technology commitment. Missing or protected evidence must be recorded as a gap or retained in an authorized private system.
