Perspective / Evidence
Let the work support the claim.
Confidence is more useful when its basis is visible. We aim to make that basis part of the account of our work.
Perception and perspective
Another reading.

Demonstration
Be precise about what was shown.
A capability claim needs a defined task, an identifiable release, and a result that can be inspected. A successful component test does not prove an entire workflow.
Limits
Leave room for what remains open.
A meaningful record includes constraints, failures, and unanswered questions. It should make clear what further work is needed before a capability can be relied on more broadly.
