Proxy configuration beside insecure, not a fifth policy — ADR 0108 closed that set at four, and both
of these tune how a request is carried rather than deciding what a name admits. A registry is the
case that needs it: image layers arrive as single requests of gigabytes and a proxy's own default
refuses them long before the workload is reached.
Absent is no limit, which is what every route already got. A limit that is not a whole positive
number of bytes takes the route with it, named in the log like a port that is not one — serving it
without the limit would carry exactly what the module said not to carry. Enforced on the declared
length where there is one, and while reading for a chunked body, which declares none: without the
second, a limit is advice.
