Validate the whole proposal before any side effect

Mon, 01 Jan 0001 00:00:00 +0000

A model can propose more than a runtime should do, and the chapter’s claim is that the boundary has to answer three separate questions in order, and fail loudly at each. Does the proposal have the right shape? Are the values usable? And may this run perform it? A proposal that passes the first two can still be refused by the third.

Run it

The boundary is the chapter’s own code. Save the first block as action_boundary.py, save the second as demo.py beside it, and run the driver with Python 3.11 or later. The standard library only: no model, no network, no service.

Measure the gap between what you generated and what you chose

Mon, 01 Jan 0001 00:00:00 +0000

Generating more candidates is only half of the work, and the chapter’s claim is that the two halves have to be measured separately. oracle@N asks whether a successful candidate was ever generated. selected@N asks whether the selector picked it. The difference is the selection gap, and it is the diagnosis: a large gap means the answers were already there and the selector is losing them.

Run it

The instrument is the chapter’s own code. Save the first block as selection_gap.py, save the second as demo.py beside it, and run the driver with Python 3.11 or later. The standard library only: no model, no network.
