Phase 1.3 done: ordering was already there, the network was not

Ordering needed no change for the third time running — resources apply
in the order declared and nothing sorts them — and is now asserted,
because sorting them for any sensible reason would have passed every
other test.

Separates ordering from readiness, which the task had run together: a
container started is not a container ready. Nothing waits, and what
needs something usable retries. That is deliberate and more robust than
start ordering, since a dependency can restart long after apply.

The network was the first thing in Phase 1 that genuinely needed
building, and the first that needed a decision: 0029 records why a shape
rather than an action, and the vocabulary is nine.
