Answer architecture round 5: the shipped packages are enus, svse, geose, geous and misc, each holding its files at its root under its manifest's namespace, and the errors use the wording a bench of the Audience chose

+- Shape, Overall: `data/geo/SE/fs.go:2` `SE`: each module embeds a tree repeating its own name, and the package names SE, US, en_US, sv_SE are unidiomatic; five thin packages plus a list replace one embed
+- Shape: `reference.go:124` `withDefaultModules`: "default modules" suggests modules that load by default, though nothing loads them; "by default" is spelled out only in the README
+- Locality, Shape: `inline.go:40` `NewTemplate`: errors are decorated twice, by hand, at four entry points
+- Locality: `fejkdata.go:101` `New`: the hidden shipped default is gone, offsetting the above
+
+Inherited architect, decided by:
+
+- Navigation, Overall: `data/sv_SE/fs.go:8` `FS`: every data file sits under a doubled folder, data/sv_SE/sv_SE/, data/geo/SE/geo/SE/, a stop at each hop of the 3am path
+- Navigation: `data/modules.go:15` `go:generate`: the module list is written twice and the manifest writer lives in a root test run from the data package
+- Shape: `data/geo/SE/fs.go:2` `SE`: a package named SE reads as Sweden beside sv_SE, and "module" means a Go package here
+- Shape: `reference.go:126` `withDefaultModules`: one concept spelled reads, defaultModules and "read by default", the last defined only in the README
+- Locality: `fejkdata.go:114` `New`: four call sites apply loadError, withDefaultModules and noDataNote in a fixed order, offset by the hidden shipped source being gone

 Valid while the shipped data stays under 100 MiB, which a gate test holds (`todo.md` item 192): `go get` fetches the whole Go module, and the `go` command refuses a Go module zip over 500 MiB (`MaxZipFile` in `golang.org/x/mod/zip`). Past it, `todo.md` item 193 moves the largest packages into nested Go modules that keep their import paths, each requiring the core release that drops the package, so no build sees it twice.

+2026-10-11, Lilleman auf Larv, from a bench of a Go test author, a data author and a
+custom-CLI builder. Serves goals 1 and 3.3. `sv_SE` ships as `data/svse`, `en_US` as
+`data/enus`, `geo.SE` as `data/geose`, `geo.US` as `data/geous`, and `misc` as `data/misc`:
+Go linters flag a capital or an underscore in a package name, and `SE.FS` read as a type.
+Each package holds its files at its root, and its manifest's `namespace` puts them under
+the namespace, so no path repeats it. The bench also chose `reads` for what a module reads
+by default and the wording of the errors naming it. Valid until a locale's lowered name
+clashes with another's.

 `New` does not check that each module a manifest reads was given. A check by module name
 would refuse a stand-in providing the same paths (goal 9.2). A check by path needs every
 reference, and only loading each indexed category finds them, which goal 13 rules out.
