<!-- Tier 5.5 Externally-Authored Query Submission template See eval/CONTRIBUTING.md for the full workflow. -->

Summary

Submitting N Tier 5.5 queries for BrainBench.

• Author handle: @your-handle
• File location: eval/external-authors/your-handle/queries.json
• Queries authored fresh (not copy-pasted from a model output)
• Slugs verified against eval/data/world-v1/ (via bun run eval:world:view)

Checklist

• bun run eval:query:validate eval/external-authors/your-handle/queries.json passes
• At least 20 queries
• Each query has either gold.relevant (with real slugs) or gold.expected_abstention: true
• Temporal queries have as_of_date set (corpus-end | per-source | ISO-8601)
• Phrasing is varied (not all the same template)
• author field matches my handle

Phrasing variety (optional self-audit)

Tick the styles represented in your batch:

• Full sentence questions
• Fragment-style ("crypto founder Goldman Sachs background")
• Comparison ("X vs Y")
• Follow-up ("And who else...")
• Imperative ("Pull up Alice Davis")
• Trait-based ("the demanding engineering leader")
• Abstention bait (answer is "not in corpus")

Notes to reviewer

Anything worth flagging — ambiguous cases, corpus gaps you found, specific phrasings you were uncertain about.
