+   One implementation of paste-or-file → server-side import with dry-run →
+   a report that names every rejected row with its SOURCE line number → an
+   editable list whose entries deactivate rather than delete. The location list
+   (CR-005) and the material list (D6) are both instances of this; building the
+   material path "the same way and against the same component, not beside it"
+   is the T8.6 instruction, and extracting the component is what makes that
+   literally true rather than a copy with the names changed.
+
+   The page supplies what differs: the API base, the sample, how a row renders,
+   and what the add-row collects. Everything generic — the file reader feeding
+   the paste box (one parser, on the server), the dry-run wiring, the report
+   roles (a report that lost rows interrupts; a clean one does not, per T4.5) —
+   lives here once.
