Make the budget calculation explicit

Your task

Return budget_usd, agents, usd_per_agent (numbers), source_ids (array).
Use the fixed source IDs. Array order follows the contract.
Do not invent unsupported values. Missing evidence must remain unknown.

Target: 70/100. Suggested active time: 10 minutes. You can keep working after that.

Show a hint

Keep all monetary values numeric.

Accuracy checks the values. Coverage checks the requested output. Time is recorded separately and never changes your score.

budget_usd: 25 points

agents: 25 points

usd_per_agent: 25 points

source_ids: 25 points

This score checks fixed evidence fields and exact types. It does not assess the quality of arbitrary writing.
