Audience member asks how the new flow worked when the parameters it would send to third parties differed from what was recorded in the old flow. Answer: recorded stubs were transformed before matching — e.g. detecting that a user identifier had a known prefixed/public format and rewriting it to the new flow's format — so the verification used the new flow's data against stubs derived from old-flow responses. No entirely new HTTP calls were added; the underwriting process itself was unchanged, only the preparation differed.
