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 — <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.
