### 51. Ship prebuilt binaries, a container image, Homebrew and Scoop, so the CLI needs no Go.
### 53. Ship prebuilt binaries, a container image, Homebrew and Scoop, so the CLI needs no Go.
GoReleaser attaches them to the release the tag workflow publishes. A checkout build prints `devel` for `--version`; the binaries carry the stamped tag.
### 1. Bind a pick to a name with `{x as n}`, read it with `{n}` and `{n.path}`, and refuse a name bound twice.
- A binding prints nothing: `{/person as p}{p}` renders `Erik Lind`, and `{p.last}` beside it `Lind`.
- A name is one pick of everything under it, drawn once: `{/country as k} {k.city.name} ({k.city.population})` is one city of `k`'s country.
- A name is visible in the template that binds it and everything that template renders, its sibling fields and a record's columns included, so one field may bind and another read.
- A name bound inside a `repeat` level picks again on every iteration; one bound outside it keeps its pick on every line.
- Refused at load: a name bound twice in one scope, and a name that is also a field or an option of the template, since options and fields share one namespace.
- Lands before item 4 changes what an unnamed `{…}` does, so the shipped data can move to names first (item 3).
### 3. Rewrite the shipped categories so facts that belong together come from one named pick.
- `sv_SE.person` and `en_US.person` bind the first name and read sex and title through it: `"first": "{.first-name as n}{n.name}"`, `"sex": "{n..sex.name}"`, a title from `{n..sex.title.name}`.
- `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.
- Needs items 1 and 2. Every shipped value must still pass its consumer's check before and after item 4.
- Needs item 1 and 2. Every shipped value must still pass its consumer's check before and after item 4.
- Re-pin seeded output in its own commit.
### 4. Draw every `{…}` afresh, keep a pick only by name, and delete `drawGroup` with the fences that held picks implicitly.
- Needs items 1–3. After it, `{/person} ({/person.first})` renders two people, `{w} {uppercase(w)}` renders `b G`, and `{/city.name}, {/country[SE].name}` and `{/country[SE].name} / {/country[NO].name}` both load.
- Deletes the token-order rules (`drawsApart`, `readFold`, `branches`, the pairwise replay), the expansion hold fence, `drawGroup` and the decisions that reverse with them. The remaining load checks are names, paths through names, cycles and the repeat cap.
- Needs items 1–3. After it, `{/person} ({/person.first})` renders two people, `{w} {uppercase(w)}` renders `b G` where `w` is a choice of letters, and `{/city.name}, {/country[SE].name}` and `{/country[SE].name} / {/country[NO].name}` both load.
- 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 and "One draw, one spelling" sections; the Linked tables section says which pick's weights govern a family, since the bound row decides.
- Re-pin seeded output and `testdata/shipped_shape.txt` in their own commits; the CHANGELOG names the grammar change.
### 24. Draw `en_US.phone`'s `exch` as a NANP central office code, and assert the rule in `TestShippedUSPhone`.
### 23. Draw `en_US.phone`'s `exch` as a NANP central office code, and assert the rule in `TestShippedUSPhone`.
`{int(100,999)}` renders a leading 1 in about an eighth of draws, which libphonenumber rejects, and the test proves the shape rather than the rule.

Both runs named the same hardest units, `drawsApart` and `readFold.reads`. Scores since 2026-09-20 range 5.7–6.1, wider than this 0.3 spread by only 0.1, so `AGENTS.md`'s "no merge lowers the last score" can block or pass a chunk by chance. The last recorded nine-seat score is 5.7, on 2026-09-30; the ratchet reads it from here until this item is decided.
### 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`.
- `..country` steps up to the nearest ancestor table named `country`, from a selected row, a drawn row or a name bound to a row: `{c..country.name}`.
- `..` 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.
- Replaces the decision "A link column after a row steps up to the parent row, and a path may not end on it".

Today only a JSON field takes one, so `misc.httpmethod`'s booleans are typed in Go and text everywhere else. Typing a shipped column changes what `json` and `sql` write, so the capability is a minor and applying it to `misc.httpmethod` is a major.
