Prove how AI decisions were made
A decision is easier to defend when the evidence is created at the same time as the decision.
Evidence Vault adds a sealed decision record to Decision Deck so every AI-driven decision carries proof of what was known, what policy ran and why the final action followed.
That gives teams two things they need when automating high-impact decisions
Evidence at the point of action.
Creates the decision record as the decision runs, before review, audit or challenge begins.
Proof after action.
Shows which evidence was used, which policy applied and where human judgement changed the path.
From scattered records to decision evidence
Most organisations can find fragments of a decision somewhere. Evidence may sit in source systems, logs, documents, workflow notes, model outputs or reviewer comments. The problem starts when someone asks why a specific decision happened.
Evidence Vault turns those fragments into one decision record. As each decision runs, it captures the evidence, policy checks, version context, actions considered, actions held back and final decision state.
Stop reconstructing decisions after the event.
Evidence Vault controls
Decision record
Create one structured evidence record for each decision.
Policy trace
Show which policy version ran and what it allowed, blocked or routed.
Evidence use
Record what evidence was used, missing or rejected.
Version context
Preserve the policy, model and workflow versions active at the time.
Human judgement
Capture review, approval, escalation and override rationale.
Verification
Seal the record so later change is visible.
When to use Evidence Vault
Use Evidence Vault where a decision may need to be inspected, defended or improved later. It is most valuable when the cost of explanation is high and the evidence behind the decision cannot be left to logs, notes or memory.
Evidence Vault is particularly useful when AI-driven decisions are governed by policy-as-code, human review or model versions that change over time. It gives teams a decision-level record of what actually happened, using the context active at the time.
Where Evidence Vault shines
Decision evidence as operating proof
Evidence Vault turns decision evidence into part of the operating method. The decision does not produce an outcome first and an explanation later. The same process that produces the outcome also produces the record. That makes each decision easier to inspect, easier to defend and easier to learn from.
How Evidence Vault works
Evidence requirement
Define what must be captured for the decision to be reviewed later.
Runtime capture
Record the evidence, policy checks, model outputs and review activity as the decision runs.
Sealed envelope
Preserve the decision record with the version context active at the time.
Replay and learning
Inspect individual decisions, compare later versions and learn which evidence, policies and review paths improve outcomes.
Business impact
Risk and compliance
Give teams clearer proof of how policy, evidence and review shaped each decision.
Responsible AI
Show how AI-supported decisions operated, including uncertainty, held actions and human involvement.
Operations
Reduce the effort spent reconstructing decisions for complaints, appeals, reviews and audits.
Product and technology
Compare decision behaviour across versions and improve the evidence captured by each workflow.
Common questions
How is Evidence Vault different from logging?+
Logs show system activity. Evidence Vault shows how the decision was made. It records the evidence, policy checks, versions, actions and review activity that shaped the outcome.
What is a Decision Evidence Envelope?+
A Decision Evidence Envelope is the sealed record for one decision. It captures the material evidence, policy version, model version, action path, human review and final decision state active when the decision was made.
How does Evidence Vault work with policy-as-code?+
Policy-as-code controls what the system is allowed to do at runtime. Evidence Vault records which policy ran, which checks passed or failed and how those checks changed the decision path.
Does Evidence Vault prove compliance?+
No. Evidence Vault does not replace legal, compliance or governance teams. It gives them stronger evidence of what happened, what was checked and why the decision followed.
Does Evidence Vault record actions not taken?+
Yes, where they mattered to the decision. The record can show when an action was held back because policy, evidence, risk or customer treatment controls changed the route.
Where does human judgement fit?+
Human judgement remains part of the governed decision process. Evidence Vault records the review route, evidence shown, reviewer action, override rationale and final outcome.
Make every AI decision easier to defend
Evidence Vault brings decision evidence directly into AI-driven workflows. Use it where the ability to prove what happened matters.
