 - `geo.SE.address` and `geo.US.address` bind the street and read locality, postal code and region through it; the locale `address` categories bind `/geo.XX.address` once. They print it whole as `{a}`, so the country record's format appears once; revise the decision "A locale's `address` restates its country record's format".

 - Deletes the token-order rules (`drawsApart`, `readFold`, `branches`, the pairwise replay), the expansion hold fence, `drawGroup`, the own-family fence and the cell-reference fences, and revises the decisions that point here. The remaining draw checks are names, paths through names, cycles and the repeat cap.
 - Fixes on the way: `{/sel}|{/sel}` panics out of `Fake` today where two draws land on rows whose cells select different rows of another table; it must render.
 - Rewrites the README's References, Draw group, Correlated fields, Linked tables, Names and "One draw, one spelling" sections; the Linked tables section says which pick's weights govern a family, since the bound row decides.

 Nothing has shipped, so "no longer paths", "where it used to fail" and "where it used to be an empty string" describe versions no reader can have installed.
 
-### 2. Step up from a row to the row it links to with `..`: `{/city[Oslo]..country.name}` renders `Norway`, and `city[Oslo].country` stays the cell `NO`.
-
-- `..` goes up one level, to the parent table, and the name after it is that parent's: `{c..country.name}`, and from a locality `{l..municipality..region.name}`. Naming any other table is a load error naming the parent.
-- It steps up from a selected row, a drawn row or a name bound to a row.
-- After `..`, `.` steps down again: `{c..country.city.name}` is a city of `c`'s country, drawn afresh.
-- `.country` after a row keeps reading the link column's cell, so the README's `city[Oslo].country` example stays true.
-- A `Fake` path and `--list` take `..` too; `List` keeps advertising direct descents only.

 ### 34. Add `{isin()}`, `{cusip()}`, `{aba()}` and `{vin()}`.
 
 `isin`: Luhn over letters expanded to digits. `aba`: 3-7-1 weights. `vin`: position 9 over the whole; a sample taking the WMI, since the check sits mid-string.
 
 ### 5. Run the nine-seat comprehension panel after the draw restructure, and file what it names.
 
-Needs items 2, 71, 3, 4 and 90. The decision "comprehension floor: every dimension and the overall at 7.0 or above; items 2, 71, 3, 4 and 90 ship with no scoring run, and item 5 scores them" suspends every scoring run and panel until then.
