Use when configuring logging in PDK custom policies using the pdk::logger macros (debug, info, warn, error) that generate log messages enriched with API instance ID, policy ID, and request ID in Omni Gateway logs, and for the convention to never log or return secrets — credentials, Authorization header values, tokens, client secrets, or raw config bytes — plus the undocumented guaranteed-delivery idiom of logging at error! with a fixed prefix to bypass log-level filtering.
