+# Research score-threshold test intent
+
+## What changed
+
+- Updated the score-threshold retrieval test plan to use the supported `direct` research intent.
+
+## Why
+
+- The test fixture used the removed `lookup` intent, causing the KnowledgeFS API TypeScript gate to fail.
+
+## Verification
+
+- `pnpm --filter @knowledge/api typecheck`
+- `pnpm --filter @knowledge/api test -- research-evidence-retrieval.test.ts`
+
+## Risks and follow-up
+
+- No production behavior changed; this only aligns the test fixture with the production query-plan contract.
