Governance layers

01 / DEFINE

Readable rules.

Keep product, security, legal, and platform constraints legible to the teams responsible for them.

02 / RESOLVE

Runtime context.

Evaluate the active environment and execution context instead of applying one static global choice.

03 / REVIEW

Attached evidence.

Retain the inputs, result, and policy version with the trace so a decision can be reconstructed later.

Policy surfaces

Control what can change—and who can change it.
