No institution-specific compromise is asserted.","evidence":"The guide calls for trusted template editors and pre-production review. It documents configuration propagation into NIM. This is a control warning, without an incident sample or measured mitigation effectiveness.","architectureImplications":"Interpretation: inventory the effective prompt-construction configuration alongside model and image versions.","governanceImplications":"Interpretation: require independent approval for changes affecting message construction or tool use.","securityPrivacyImplications":"Interpretation: restrict template modification rights and verify effective overrides before release.","caveats":"Living vendor guidance, not independent validation; sandboxing and output integrity are separate properties.","streamIds":["nvidia"],"roles":{"sales":"Interpretation: The problem is an assistant that passes ordinary tests but inherits unreviewed behavior from imported configuration. Engage application owners, developers and security. Ask who may modify prompt construction, how changes reach production and what external actions the assistant can take. A bounded configuration review for one workflow could clarify ownership and identify uncontrolled changes. The value hypothesis is more dependable release governance, subject to testing. Do not characterize every custom template as malicious or promise that a license, sandbox or review eliminates prompt injection.","engineering":"Interpretation: Capture the effective configuration at deployment rather than reviewing only a repository default. Require approved model artifacts, a test identity and synthetic records. Validate precedence through a harmless controlled change and confirm that unauthorized edits are denied. Compare output behavior with the accepted configuration on benign and adversarial cases. Keep external tool execution behind independent authorization. The proof of value should demonstrate traceability from reviewed artifact to running service and rollback without exporting sensitive traces. It does not certify the model itself.","delivery":"Interpretation: The application service owner should coordinate developers, security reviewers and platform operations. Establish a change log, approval workflow, regression corpus and rollback procedure. Dependencies include reviewer time and visibility into deployed settings. Train maintainers to inspect effective behavior after updates and users to report unexplained output changes. Review configuration before broader adoption and after supplier changes. Proposed acceptance criteria are complete artifact traceability, blocked unauthorized edits and successful rollback of a staged change. Risks include emergency overrides and behavioral drift outside the test corpus."},"retrievedAt":"2026-09-10T03:01:26Z","enrichedAt":"2026-09-10T03:02:10Z","enrichmentBasis":"retrieved source","accessibilityWorkforceImplications":"Interpretation: teach developers and reviewers to inspect non-weight artifacts; user accessibility still needs application testing.","procurementImplications":"Interpretation: request configuration provenance and a documented change-notification process.","operatingModelImplications":"Interpretation: name an owner for effective configuration review and behavioral regression testing.","updateExplanation":"Exact URL absent from full-archive search.
