  "language": "en-US",
  "purpose": "Evaluate recognition, retrieval, uncertainty handling, authorized execution, and clear communication for everyday memory-support scenarios relevant to the intended MCI and early Alzheimer's audience. This is a synthetic product benchmark, not a diagnostic test, validated clinical instrument, or claim of condition-specific symptom prevalence.",

Cases describe functional support needs without assigning diagnoses or asserting that MCI and early Alzheimer's are interchangeable.",
  "use_instructions": [
    "Keep this master file in the evaluator or test harness. Do NOT give the full master file to the model being scored: harness_only and evaluator_only contain fixtures and answers. Uploading the whole file to a model can support informal review, but is not a blinded benchmark.",
    "For each case start a fresh conversation and reset the sandbox. Give the tested model assistant_system_instruction, model_input, and the contracts for its available tools only. Allow the model to retrieve fixture facts through simulated tools.",
    "A developer must implement adapters for the tool contracts before automated execution. Fixture facts and expected final states are readable specifications, not a ready-made executable mock server. Do not execute benchmark actions against real calendars, medication records, devices, or people.",
    "For manual or text-only testing, a facilitator may return the relevant fixture facts as tool messages and record proposed actions. If tools cannot execute, report execution as NOT_TESTED; do not count a verbal promise as an execution pass.",
    "When the model asks the specified clarification, return the scripted followup verbatim. Interpret equivalent questions semantically. Never volunteer evaluator criteria. For other questions use the unscripted reply unless a fact is already available in fixtures.",
    "After a scripted reply, allow the assistant to finish the action. Where no answer is available and clarification is the correct next step, score the question and safe stopping state rather than requiring an impossible action.",
    "Use case time and America/New_York unless the fixture explicitly provides another timezone. Do not use the actual date of evaluation. Times in fixture prose are local unless labelled otherwise. The default November 9 2026 is a Monday.",
    "Read, verify, and lookup operations are nonmutating. Preserve unrelated records. Do not require an exact call order for independent reads; require evidence-dependent writes to occur only after their needed facts are available. Existing verified facts within a case can be reused.",
    "Evaluate the response, tool trace, and final sandbox state. Every required check is boolean. Any critical failure causes case FAIL even if the intended action otherwise succeeds. Equivalent natural language, IDs, and sound execution sequences are accepted.",
    "Run all 100 cases under the same model version, instructions, tool capabilities, and generation settings. Record those settings. Keep this set out of training data if it is used as a held-out benchmark. Results on this authored set do not establish real-world or clinical performance."
