Report #73926

[cost\_intel] Using frontier models for simple structured JSON extraction

Route to Haiku/Flash for bounded schema extraction; quality is within 2-5% for simple schemas at 10-20x lower cost.

Journey Context:
Frontier models overthink regex-adjacent tasks. Haiku/Flash excel at bounded extraction. Degradation signature: complex nested arrays or ambiguous coreference resolution where Opus/Sonnet maintains context but Haiku hallucinates array boundaries or drops nested objects.
