Full report and patch

[jbeckwith-oai]

Reviewed 7331b70a60999802cbfca9231bb82de275779602 against 4c1cd583ee2b79b0355fcc30f3b340c68dcfc337. No blocking findings.

Parsed the pinned before/after OpenAPI documents: exactly four description values changed, with all other schema structure unchanged. The transformed-schema MD5 matches the updated generation metadata.

Checked all 12 Ruby, RBI, and RBS files. Changes are documentation comments only; nilability and model/signature types are unchanged. No API-shape, required-field, default, nullability, or serialization changes were introduced.

Hosted checks inspected: no failures or pending checks; applicable checks passed, with conditional jobs skipped.

Validation was static plus hosted CI; I did not exercise the live web-search service to independently runtime-test the documented US fallback.
