Written after porting the first real workload end to end. Every step
exists because skipping it cost something, and the ratio is recorded
because it is the lesson: six attempts, one real bug, and the mesh was
right every time.
The rule worth carrying out of it: read the host's log before
theorising. A declaration that was sent and not applied says so there
and nowhere else — it took an hour to look, and the answer was one line.
