Mechanism
A retrieval workflow contains both a current policy and an obsolete version. Metadata distinguishes the two sources, but the retrieval process does not consistently enforce the approved status.
Supporting Material
A controlled comparison records what is retrieved when the source filter is absent and when it is applied.
The supporting material may include:
- the test configuration;
- the documents available to the workflow;
- retrieved chunks and their metadata;
- the context passed to the model;
- the resulting answer;
- the trace connecting the stages of the run.
Potential Consequence
Obsolete or unauthorized information may enter the model context and influence the answer presented to a user.
In a consequential workflow, this could contribute to an incorrect customer response, an unsupported action or an unreliable business decision.
Existing Strength
The source records already contain metadata that distinguishes current and obsolete material.
Control Gap
Metadata alone does not establish an effective source boundary.
The restriction depends on trusted application logic applying the correct filter consistently, preventing inappropriate override and preserving enough information to reconstruct what happened.
Remediation
Apply the source boundary through trusted workflow logic, test both permitted and prohibited retrieval paths and define how the system should respond when adequate authorized material is unavailable.
Acceptance Evidence
A repeatable test should show that only permitted sources enter the retrieved context under the defined conditions.
The configuration, retrieved material and trace should be sufficient to reconstruct and compare the result.
