Glyph never prescribes

Of all the things a clinical model could be allowed to do, one is forbidden absolutely: Glyph does not prescribe. It does not diagnose, it does not decide, and no amount of confidence in its output changes that. The rule is short, and it is the most important sentence in the system.

The temptation to break it is real, and it is strongest exactly where the need is greatest. Bangladesh has one doctor for every fifteen hundred people. There are villages a doctor reaches rarely and patients who will never see one for the complaint they have. In that gap, a model that could just write the prescription looks like mercy, not overreach. Why make a sick person wait for a human when the machine already knows the answer?

Because the machine does not know the answer. It produces an answer, fluently, whether or not it is right, and it produces the wrong ones in the same confident voice as the right ones. A prescription is an action with consequences a model cannot be accountable for, and accountability is not a nicety in medicine. It is the thing that makes the act permissible at all.

So the model stops short of the act, every time, by design rather than by reminder. It can suggest what a doctor might consider. It can surface an interaction, draft a note, flag a danger. What it cannot do is turn any of that into a prescription, because the step that makes a prescription real, a signature, is reserved to a licensed human and the model has no way to take it.

This is not Glyph being cautious about liability. It is Glyph being correct about what a prescription is. A prescription is a person, a named and trained and accountable person, taking responsibility for a drug going into a body. Remove the person and you do not have a faster prescription. You have a guess with a dosage. The model's refusal to prescribe is not the limit of its usefulness. It is the precondition for being allowed to be useful at all.
