AI-Driven Mortgage Prepayment Shock Forecasting System using LangChain & Claude 4 Opus

Build a LangChain LCEL chain using `ChatAnthropic(model='claude-3-opus-20240229')` (or Claude 4 Opus equivalent) and `JsonOutputParser`. Pass mortgage coupon, WAC, and rate delta parameters to output predicted CPR percentage.
Adaptation plan
Keep the source stable, then change the prompt in a predictable order so the next run is easier to evaluate.
Keep stable
Hold the task contract and output shape stable so generated implementations remain comparable.
Tune next
Update libraries, interfaces, and environment assumptions to match the stack you actually run.
Verify after
Test failure handling, edge cases, and any code paths that depend on hidden context or secrets.
