// Evidence & proof
Don't assert it works. Prove it.
Everyone else asserts that disaster recovery works, upgrades are safe, and the experience is improving. Kairn proves it on a loop — and keeps audit-grade receipts you can hand to a regulator.
The proving loop
Clone. Exercise. Prove. Destroy.
1
Clone a twin
A fully isolated digital twin of the whole stack — same topology, same data shape.
2
Exercise it
Run deploys, patches, full-stack upgrades, and failover drills against live services.
3
Trend the experience
Measure real UX against SLOs and prove the line is moving the right way.
4
Emit the evidence
Immutable, audit-grade proof — signed, timestamped, and queryable.
5
Destroy it
The twin goes. The proof remains in the ledger forever.
What an evidence record holds
Every claim, traceable to its source.
✓The decision trace — observation, reasoning, policy match, approval.
✓The diff & logs — exactly what changed and the execution output.
✓Owner & approver — who signed off, and against which guardrail.
✓Post-change verification — the proof it actually worked.
