Report #74983

[frontier] LLM-as-judge routing introduces non-determinism and latency in multi-agent orchestration

Use regex-constrained structured generation \(SGLang/Outlines\) to force valid routing decisions deterministically in a single token generation pass

Journey Context:
Using separate LLM calls to decide which agent handles a request adds 500ms\+ latency and temperature-induced flakes. Frontier systems now use structured generation with regex constraints \(e.g., \`^\(search\_agent\|code\_agent\)$\`\) to deterministically route in one pass, eliminating the need for a 'supervisor' LLM and ensuring reproducible execution graphs.
