K3-21 C, red. `structure` read `parent` as a document number only; a
`segment_id` answers to no key its lookup builds, so every `--shell-parent`
pointer rendered unresolved (`parent: p1977?`, 675 of 675 on one standard)
and both declared parents in each segmented golden render `parent: s0?` --
while the concept each names stands in the bundle.
Held here: a segment pointer resolves among the concepts sharing the
pointer's `source_file`; the same id in another document is not the parent; a
pointer naming nothing still carries `UNRESOLVED_MARKER`; a parent that is a
document number resolves as before; the flagged fixture build's index renders
no parent unresolved.
3 of 5 red on 46e555d; the two green are the unchanged routes.
