zespan.autopatch() or a specific patch_X() function in Python, or use the SDK’s wrap_X() / patch_X() functions in TypeScript, and Zespan traces the calls your existing code already makes to that library. No changes to call sites, no separate sync process, and nothing leaves your app until the library method you patched is actually invoked.
