WHEN AI DECIDES, YOU ANSWER
AI accelerates decisions. Explainability lets you answer for them.
Explainable AI infrastructure records the full context behind every decision a system or AI agent makes. The state, inputs, and rules at the moment it acted is stored as an immutable, queryable log. It doesn't explain how a model thinks; it lets you reconstruct exactly what the system knew and why it acted.

What it means
Reconstruct the exact state, inputs, and rules a system or agent saw at the moment it decided — on demand, at any point in the past.

What it isn't
Not a window into how a model “thinks.” We explain the context the decision was made on — never the inner workings of the model itself.

Why it holds up
Because the record is immutable and complete, a disputed decision is a query, not a forensic exercise. The answer is already there.
