What this category tests

Does the brain return the exact KB-* source label, not an internal ID?

How the test works

After ingesting documents, the test asks the brain to cite specific sources. Citations must use the KB-* label format the document was stored with, never the internal src_* IDs.

Why it matters

Source IDs are the brain's contract for provenance. If they're wrong, evidence can't be traced.

⚙️ 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 3 times per test run. A pass requires score ≥ 85 and no critical failures.

🔬 Technical Instructions (raw prompts sent to AI)

🔧 ① Setup Instructions 1296 chars

Generate two documents about the same person but with different invoice IDs. Ingest both.
The invoice IDs should be very similar (e.g. INV-7A and INV-7B). Ask which source_id contains a specific invoice.

Requirements:
- Document A: "Invoice <ID-A> belongs to <person>."
- Document B: "Invoice <ID-B> belongs to <person>." (same person, different invoice ID — differ by last character only)
- source_ids: KB-{{RUN}}-SID-004-A-v1 and KB-{{RUN}}-SID-004-B-v1
- Question asks which source_id supports invoice <ID-A>.

Check: only Doc A's source_id for Doc A's invoice. The invoice IDs differ by only one character — the agent must get this right.
