What this category tests
Can the brain answer questions that require combining information from 2+ documents?
How the test works
Documents form chains (e.g. Doc A: 'X9 is the velvet pouch'; Doc B: 'velvet pouch contains a silver locket'). The test asks 'what does X9 contain?' which requires Doc A → Doc B reasoning.
Why it matters
Real questions often span multiple documents. Single-doc retrieval is not enough.
⚙️ How a single rep runs
① Generate
Model creates 2 synthetic documents and 1 question with unique canary tokens
→ Fresh content per run prevents memorization and proves real retrieval
② Ingest (MCP)
Model calls brain_ingest to store the 2 documents
→ Tests the brain's storage and indexing pipeline
③ Query (MCP)
Model answers the question using brain retrieval tools (search, fetch, context_pack, etc.)
→ Core test — does the brain return correct evidence and let the model build a faithful answer?
④ Evaluate
Model judges the answer against ground truth (the document it generated in phase 1)
→ Produces a score 0–100 with detailed sub-scores (retrieval, fidelity, reasoning, etc.)
This rep is run 5 times per test run. A pass requires score ≥ 85 and no critical failures.
🔬 Technical Instructions (raw prompts sent to AI)
🔧 ① Setup Instructions 1577 chars
Generate two synthetic documents forming a two-step reasoning chain, then ingest both.
Requirements:
- Document A: States that a fictional object with a unique code/ID IS a second fictional object. Example: "The item with code Q7 is the cobalt key."
- Document B: States a property of that second object. Example: "The cobalt key opens Drawer 3."
- Use fictional names/codes only. Do not use real-world facts.
- Source IDs: KB-{{RUN}}-XSR-001-A-v1 and KB-{{RUN}}-XSR-001-B-v1
- Generate one question that can only be answered by combining both documents. The question should ask about the property of the original code, forcing a two-document join.

You have access to MCP Knowledge Brain retrieval tools. Use ONLY those tools — do not use memory or outside knowledge.
Question: {{QUESTION}}
You must retrieve from the brain and combine information from multiple sources to answer.

⚖ ③ Judge Instructions 1019 chars
You generated the following test data and ingested it into a knowledge brain.
A separate AI then answered a question requiring it to combine two documents.
Evaluate whether it found and used both documents correctly.
Ground truth:
{{SETUP_CONTEXT_JSON}}
The tested AI's answer:
{{EXEC_ANSWER_JSON}}
Scoring criteria:
- retrieval_tool_use (0-20): Did it retrieve BOTH required documents? Partial retrieval = partial credit.
- evidence_fidelity (0-20): Are both source_ids cited correctly? Quotes accurate?
- reasoning_correctness (0-20): Is the final answer correct? Is the join logic valid?
- uncertainty_discipline (0-15): Did it avoid fabricating a join that isn't supported?
- output_format_compliance (0-15): Valid JSON, complete schema?
- adversarial_resistance (0-10): Full marks (not adversarial test).
Critical failure conditions:
- Missing either required source_id
- Any hallucinated source_id
- Wrong final answer
- Label is DIRECT (requires CROSS_SOURCE)
Return ONLY this JSON:
