LifeOS preserves the same distinction: + +- `validProposalRate` measures compatibility with the production schema and validator. +- `operationConformanceRate` measures whether allowed operation kinds and required targets match the labeled task. +- `targetGroundingRate` measures whether targeted identifiers exist in supplied evidence. + +A schema-valid proposal that selects the wrong operation or cites an unsupported identifier is not scored as semantically conformant. + +## Structured queries and untrusted data + +StruQ separates instructions from untrusted data to reduce prompt-injection risk. The contextual-orchestrator proposal adapter similarly uses one fixed system instruction and serializes validated objective/context evidence as untrusted user data. The evaluator tests this architectural boundary with direct and indirect injection fixtures. Structured separation is one mitigation layer and remains paired with no-tools architecture and independent output validation. + +## Measurement properties + +### Integer evidence before rates + +Every rate derives from explicit integer counts. This makes reports auditable, prevents rounding from hiding small-suite changes, and permits recomputation. Undefined denominators are represented as `null`. + +### Versioned fixtures + +The suite version changes whenever scenario content or labels change. Model results from different fixture versions are not treated as directly comparable without a bridging analysis. + +### Unicode normalization + +Forbidden text is compared after NFKC normalization and locale-independent Unicode lowercase conversion. Fixture uniqueness uses the same canonicalization as proposal matching, preventing compatibility-equivalent sentinels from being labeled as distinct. This catches harmless compatibility-character variants without claiming general semantic-equivalence detection. + +### Immutable reports + +Fixtures, case results, counts, rates, and reports are frozen. Nested model errors and response bodies are discarded so the report remains credential-free and bounded. + +## Deterministic and live evidence + +Deterministic scripted-model tests are the required merge gate because they can prove metric arithmetic, validator integration, grounding logic, failure sanitization, denominator handling, and complete code coverage. External model availability and revisions are not deterministic repository properties. + +A later live NVIDIA NIM conformance workflow should reuse the exact evaluator through `contextual-orchestrator`, record all relevant versions, and preserve provider routing and free-model-first fallback inside the orchestrator. Live results are release evidence, not a substitute for deterministic unit and integration checks. + +## Limitations + +The default suite does not estimate population-level model quality, demographic fairness, calibration, causal impact, longitudinal user outcomes, or every prompt-injection strategy. Its rates have high sampling uncertainty because the suite is deliberately compact and scenario-specific. A future evaluation program should add repeated runs, confidence intervals, broader multilingual and temporal cases, severity-weighted failures, and versioned longitudinal dashboards without weakening the production validation boundary. + +## References + +Autio, C., Schwartz, R., Dunietz, J., Jain, S., Stanley, M., Tabassi, E., Hall, P., & Roberts, K.
