The security boundary is a shape before it is a rule: DERIVED hangs off
content, ATTACHED hangs off the file, and two arrows starting from
different places carries the argument faster than the paragraph
explaining it.
Sketched inline rather than left as "add a diagram", so whoever writes
the page inherits the structure — including the parts a diagram is
uniquely good at showing: that both tables point into the same artifact
space (hence why one cannot be folded into the other with a kind
column), and that DERIVED.blob_hash is optional where ATTACHED.blob_hash
is not.
