Evidence identity
What exact evidence object, version, source, or record supported the original action?
AI Evidence Governance
What if the evidence changes before AI execution?
A system can be supportable at one moment and unsupported later. If the evidence behind an action changes before execution, the important question is not whether the evidence was once valid. The important question is whether it still has standing when consequence is about to occur.
The stale-evidence problem
A model, agent, workflow, or approval process may rely on records that were true when first captured: identity data, account state, policy status, environmental conditions, risk classification, customer consent, inventory state, financial limits, or other execution-relevant facts. If those facts materially change, old evidence can become historically accurate but presently insufficient.
What a defensible execution record should show
Continuity
Can the system show that the evidence used at execution is the same evidence—or a governed successor—to what was originally relied upon?
Material change
What changed, when did it change, and why could that change affect execution standing?
Revalidation
Was the proposition evaluated again against the changed evidence before binding or commitment?
Refusal or hold behavior
If support was lost, did the system stop, narrow, hold, deny, or escalate rather than execute on stale standing?
Replay
Can a reviewer reconstruct the original support, the change, the revalidation decision, and the final outcome?
Executable proof example
New evidence supersedes admitted evidence
TA14-EA-000017 is an executable artifact for this exact changed-evidence failure class. The frozen specification tests whether evidence supporting a pending consequence has been materially superseded by newer evidence. The bounded result is HOLD when present admissibility can no longer be carried forward without re-evaluation.
Inspect TA14-EA-000017 →Historical validation is not always present standing.
A prior approval, validation, test result, or evidence package can remain historically true while no longer being sufficient for a later execution decision. That distinction matters in finance, autonomous workflows, enterprise infrastructure, AI governance, healthcare, and other domains where conditions can change between proposal and consequence.
TA-14 examines whether the evidence actually retained execution standing under the changed condition. The architecture under review remains sovereign; the examination does not rewrite it into TA-14 terminology.
Frequently asked questions
Can evidence be authentic and still be unusable for a current AI decision?
Yes. Evidence can remain authentic and historically accurate while becoming stale, superseded, incomplete, or no longer sufficient for the present execution decision.
What should happen when material evidence changes before execution?
The system should identify the changed evidence, determine whether it is material to the pending consequence, revalidate the proposition, and preserve the resulting hold, denial, escalation, or continued support.
Does a prior validation prove present execution standing?
Not necessarily. A prior validation can remain historically valid while no longer supporting the current action after relevant conditions or evidence change.
Related execution-evidence problems
Authorization changed too?
Examine whether the authority basis still had standing at execution.
Execution already happened?
Reconstruct whether the agent executed on evidence or authority that no longer supported the action.
System says it stopped the action?
Examine what proves commitment or execution did not proceed.
Commercial examination
Have a stale-evidence or changed-condition problem?
Start with a $249 Execution Evidence Snapshot when you need one narrow answer. Use the $750+ Execution Claim Review when the question requires changed-condition testing, failure behavior, authority analysis, or replay. Payment buys examination work—not a favorable result.
