Signal · Assurance
A metric should not travel alone.
Keep a metric passport connected to its sources, calculation, limits and review status—and trace what needs reconsideration when an input changes.
The Governance Spine · Governance in practice
Practical insights on connecting evidence, responsibilities and human review—while keeping decision authority with the responsible institutions.

One framework · four connected questions
Use the framework to examine a gap, make it visible, connect it to an authorised decision and preserve a record that can be reviewed.
Find the gap
Where have evidence, responsibility and action become disconnected?
Explore FractureMake it visible
What has changed, how do we know, and who needs to assess it?
Explore SignalConnect the decision
Who reviews the evidence, who decides, and what happens next?
Explore SpineMake it reviewable
Can another reviewer reconstruct the basis, scope and limits of the decision?
