Preflight Agent Work Opportunity

opportunity_preflight

Agent work opportunity -> deterministic attempt, verify-first, or abandon preflight using caller-supplied cost and selection assumptions plus dated platform evidence. Returns break-even probability, expected surplus, hard gates, and source-linked evidence. No claim, bid, payment, or submission. Payment challenge and credentials are bound to GET https://agents.samedaydesk.com/work/opportunity-preflight, not mcp://. Retry the identical authorized arguments and credential.
