User: 'the python would have to define the payload in a simple text or binary format as the request and then the extension pipeline in C11 would do the ops and provide the output in another binary or text blob/s.' This is the SUBPROCESS model, not a stateful CPython C extension."
2026-06-08_2 = "v1 'build it now' revised to 'build only when hard constraint surfaces'. User: 'only worth it if I reach a hard constraint that I cannot solve with an existing python package.'
