Closes #1

What

Four additions both consumers were about to write by hand. errorText shows a refused answer in the reader's own language, filling the template its code names from the values the answer carries and speaking the server's own words when no template fits, with the caller supplying the templates and the fallback words so both stay translatable. globCatalogs turns the lazy chunks a bundler globbed into the loader a catalogue entry wants, reading the locale from each file's own name so no caller rebuilds a path. A new ./testing entry carries resetLocale, which takes every named domain and the display locale back to their sources between tests. And startLocale now shows the default locale from the moment it is asked, so nothing answers en-US to a consumer whose sources are written in another locale.

CI also loads every entry by its package name rather than one file by path, so a broken exports map fails the build instead of shipping.

Why

Gophenberg already renders error codes and loads globbed catalogues through its own copies, and AlphOne is about to need the same two. The renderer waited for a second wire shape before its signature could be designed rather than guessed, and now that both exist the product half is only the template map and the fallback sentence, which is what the caller passes in.

Testing Instructions

None.

📝 Walkthrough

Walkthrough

The package adds shared error formatting, lazy catalog loading, locale reset support, and immediate default-locale state. It exports the testing entry point and validates all published entry points in CI.

Changes

Localization utilities

Layer / File(s) Summary
Catalog and error APIs
src/catalog.ts, src/errors.ts, src/index.ts, test/catalogs.test.ts, test/errors.test.ts
Adds globCatalogs for lazy locale-based catalog loading and errorText for translated refused-request messages with metadata interpolation.
Locale state and test reset
src/start.ts, src/testing.ts, test/runtime.test.ts, test/testing.test.ts
startLocale records the configured default locale before resolution. resetLocale clears catalog data and restores the selected locale.
Package surface and release validation
package.json, .github/workflows/ci.yml, CHANGELOG.md
Exports ./testing, checks all package entry points in CI, and documents the new APIs and locale behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 29ca1

The new error formatting can crash when a server-provided code matches an inherited object property, preventing the intended error message from being produced. The PR should not merge until this input-handling issue is guarded or explicitly accepted by the owner.

- Line 16: Update PLACEHOLDERS and its formatting flow to recognize named
floating-point placeholders with optional precision, such as %(min).2f, so
missing metadata is detected before sprintf and the server message or fallback
is preserved; add a test covering the missing-value case.

In `@src/start.ts`:
- Line 18: Clarify the documentation for defaultLocale to state that it is
displayed while resolution completes and that no catalogue is loaded during this
temporary state.

In `@src/testing.ts`:
- Around line 13-16: Update the resetLocale flow to honor selective domains
instead of calling resetLocaleData for each domain and then globally. Preserve
unlisted locale data while clearing only the listed domains, or remove the
domains parameter and document global-reset behavior; add a regression test
covering both listed and unlisted domains.

Guard template lookup against inherited properties.

templates[refused.code] can return inherited values such as toString or constructor. filled() then calls .matchAll() on a non-string value and throws instead of returning the server message or fallback.

Use an own-property check before calling filled().

Proposed fix
-	const template = refused.code === undefined ? undefined : templates[refused.code]
+	const template =
+		refused.code !== undefined &&
+		Object.prototype.hasOwnProperty.call(templates, refused.code)
+			? templates[refused.code]
+			: undefined
