The handoff binder is a URL that regenerates itself

The SOW has a line item called "documentation," and everyone knows how that ends: a PDF that's wrong within a month.

This handoff works differently. The client's internal endpoints are exec scripts: files in a folder, each one already a URL. At handoff you call the generator once; it reads the scripts and produces an OpenAPI spec, served at its own URL. That's the binder.

Six months later the client's new hire reads it, and it's still true: when the scripts changed, someone re-ran one POST and the spec followed. Nobody sat down to write documentation, and nobody will ever sit down to update it.
