Comparing the per-node digest against an engine that does not record one is comparing against nothing, and reporting every node as changed on every sync for ever — which is what a client newer than its engine did, since `NodeDef` drops fields it has never heard of. A node is named now only when both sides carry a digest, so a no-op sync is `unchanged` again and the signal one syncs for is back. That silence had also been the only sign of the mismatch, so sync now names it: one line saying the engine stored no record of what a node's code reaches, with both versions in it and what to run. Bumped to 0.1.6 — the digest changed the stored document's shape, and a version that does not move makes two different engines indistinguishable, which is the thing it was made load-bearing for a day ago. `— draft` was printed whenever there was simply nothing to publish, which reads as work left unfinished. It is said only when a draft is genuinely there, and `— published` when one was.
