+`..` after a row steps up to the row its link column names, and the parent table's name
+follows it, as a folder's does in a filesystem path:
+
+```sh
+fejkdata -d ./mydata 'city[Oslo]..country.name'       # Norway

+fejkdata -d ./mydata '{/city as c}{c}, {c..country.name}'  # Oslo, Norway
+```
+
+It steps up from a selected row, a drawn row or a [name](#names) bound to a row, one level
+per `..`: `{l..municipality..region.name}`. After it, `.` steps down again, drawing
+inside the row stepped up to. `.country` after a row still reads the link column's cell,
+`NO`. A `..` that names anything but the parent table is an error naming the parent, and
+so is a selector after a `..`, which could name a row outside the one stepped up to:
+select rows before the `..`. `--list` advertises no path with a `..`. At the start of a
+reference, `..` is the folder above ([References](#references)).

-  the drawn locality's municipality, and
-  `geo.US.locality[1714000].municipality.region.name` Chicago's state.
-- A path ending on it is refused at `New`, `NewTemplate` and `Fake` alike, naming the
-  parent's key column and the parent's format spelled as paths: with a `country` format
-  of `{name} ({alpha2})`, `city[Oslo].country` names `city[Oslo].country.alpha2` and
-  `{/city[Oslo].country.name} ({/city[Oslo].country.alpha2})`. `List` leaves such a path
-  out, and a record's link column still holds the key, since it is a column, not a path.
-- A path may not step back down into a child table after a step up:
-  `city[Oslo].country.city.name` could be Oslo or a city of Norway drawn afresh, so it is
-  refused, naming the path to the row it stepped up from, `city[Oslo].name`, and the path
-  down from the parent, `country[NO].city.name`; after a drawn row, `city.country.city.name`

-- A route through another row is another path to the same data, not a second spelling:
-  `city[Oslo].country.name` and `country[NO].name` both load.

 2026-10-04, Lilleman auf Larv. Serves goal 3. The nine-seat panels in `todo.md`'s git history, 2026-09-22 to 2026-09-30, held the score between 5.2 and 6.1, with Locality lowest at every seat, and the hardest units are the draw fences item 4 deletes. Items 4 and 90 delete or move what the earlier items touch, so a scoring run before item 90 merges would score code about to go. Items 2, 71, 3, 4 and 90 are the round `AGENTS.md`'s comprehension rule lets merge below the floor, a restructure the maintainer approved. No scoring run or panel runs until item 5, which runs the nine-seat panel and larv-review's scoring run. The scoring run writes this entry's first scores. Valid until item 5 runs.
