C4, first wave. Twenty places each stored the same fact — how to translate when the host never installed vue-i18n — and two of them, usePplrT.js and useNeighborT.js, were whole-file near-duplicates at Jaccard 0.82. That pair was the curation audit's evidence that the guard was being COPIED rather than shared. Both now call library/composables/useOptionalT.js and keep their public names, so no call site changes. ★ THE SPEC ASKED FOR (namespace, fallbackCatalogue) AND THE CATALOGUE IS UNNECESSARY. Every copy imported its own English JSON and hand-walked it after stripping the namespace prefix. But library/i18n builds `messages[locale][area]` keyed by the JSON's own filename, and tStatic() already walks that tree and already falls back to English. So `import enPplr from '.../en/pplr.json'` was a second copy of bytes the bundle already had, and the helper takes one argument. ★ AND IT IS NOT A SIZE REGRESSION, which was the one good reason the narrow import might have existed. The build NARROWS library/i18n's catalogue glob per bundle to the areas internal/i18n-areas.mjs finds in that bundle's source graph (check:i18n-treeshake). A bundle that says 'pplr.' gets the pplr area, not the other thirty. Verified before writing the helper, because "the obvious dedup makes every bundle carry every locale" would have killed it. Resolution order, each step earning its place: the host's own vue-i18n when it installed one, so a host managing locale keeps control; then tStatic, which honours the runtime locale and falls back to English; then the key itself, so a missing string is visible rather than blank. The middle step also covers i18n being present but empty — i18n.t() returns the key unchanged, which every copy of this pattern already treated as "not found". Verified by _qa-cycle/02-builder-cycle/_chk-c4-optional-t-equivalence.mjs: 18 assertions across all three host states, with a branch-for-branch equivalence check against the old hand-written implementation and two negative controls. It extracts and executes the module source, because useOptionalT imports vue-i18n and an i18n index that calls import.meta.glob, which plain Node cannot run.

You are a programmer (or an agent) building a map. This is the menu of REUSABLE,
parameterized pieces the shared library/ offers. Import what you need with the @map/…
alias; build your own custom code in your app-profile's src/ folder. Do NOT edit
anything listed here unless you know what you're doing — these are shared across every map,
and a change here can break other maps.
- Three zones:
library/(this menu — reuse, don't edit) ·plugin-designs/<map>/(your sandbox — build anything) ·internal/(the build machine — never touch). - To make a new map: copy
plugin-designs/template-bundle/, read its README, list your requirements, pick from below.

API / data sources (@map/api)
The library provides the data-source mechanism; you declare WHICH sources your map uses
in your own src/api/sources.json. Add a REST API, CSV, or MCP source by adding one entry —
no code. Mechanism (do not edit): @map/api/_registry.js, @map/api/DataSourceManager.js.
Colors (@map/colors)
The library provides the color-strategy registry (the mechanism). Shared color taxonomies
(religion, adoption, engagement, language-family) live here. Your map's OWN colors live in your
app-profile's src/colors/ folder — strategy .js files auto-merge OVER the shared set
for your map only, so editing them can't break other maps. Mechanism (do not edit): @map/colors/_registry.js.
