<p class="note">
Solid fill is <b>curated</b>: governance writes it, a pull request reviews it.
Hatched outline is <b>observed</b>: a harvester writes it nightly and no one
edits it by hand.<br><br>
The two navy edges are the seam &mdash; <code>materializedAs</code> and
<code>physicalizedIn</code>. They are the only place the two worlds meet,
and the only mapping a steward has to confirm.
