Subject: [PATCH 1/2] Adapt localization framework from DigUp PR #34

Adapt the localization infrastructure and Traditional Chinese resources from
https://github.com/ARahim3/DigUp/pull/34, source commit
ef69d2658fbdd5885626ddc68e5e7b12f7523fa7, to current upstream main.
Credit for the original framework and Traditional Chinese work belongs to
the author and contributors of PR #34. This commit is an adaptation, not a
claim of original authorship.

Keep the upstream product identity, update settings, and permissions.

+# Interface localization
+
+DigUp follows the language selected for the app in macOS, with English as its development language and fallback.
+Traditional Chinese uses `zh-Hant`, including the system's `zh-TW` preference.
+
+The `DigUpLocalization` target contains `L10n` and these resources:
+
+```
+Sources/DigUpLocalization/Resources/
+├── en.lproj/       Localizable.strings, InfoPlist.strings
+└── zh-Hant.lproj/  Localizable.strings, InfoPlist.strings
+```
+
+`L10n.text` looks up static interface text. `L10n.format` formats display values with positional `%1$@`, `%2$@`, etc.
+The English format is also the lookup key. Pass already formatted strings (for example a count's `.formatted()` value),
+and escape a literal percent as `%%` in format strings. Translations may reorder or omit an argument; Chinese need not
+include an English singular/plural noun supplied by the calling code. Keep both English noun forms for existing English
+plural behavior. `String(format:)` duration formats such as `%.1f h` are translated before their existing formatting call.
+
+To add a language, add its `.lproj` directory with both files and the same interface keys. Keep permission descriptions
+consistent with the English Info.plist. Run `swift test`, build with `./build.sh`, and inspect the packaged app's UI in
+both languages, including long explanatory text and strings with counts, percent signs, and file names.
+
+`build.sh` embeds the SwiftPM resource bundle in `Contents/Resources`. It also copies each language's `InfoPlist.strings`
+into the main app bundle so macOS can localize its permission prompts. This step matters: launching from the build
+folder alone does not prove that the distributed `.app` includes its translations.
+
+Search terms, tokenizer behavior, model prompts, file paths, stored settings keys, helper commands and diagnostics are
+not localized. Sample queries shown in the UI may be translated; they are examples, not changes to search processing.
+System error descriptions and third-party UI use the localization supplied by macOS or the dependency.
+
+
+## Origin
+
+Adapted from [PR #34 by max0071001](https://github.com/ARahim3/DigUp/pull/34), through commit `ef69d2658fbdd5885626ddc68e5e7b12f7523fa7`, onto current main `ec28973`. This is the original author’s localization framework and translations, not newly authored work. Historical screenshots and test counts are omitted because this rebased build has not been validated on macOS.

Subject: [PATCH 2/2] Add Simplified Chinese UI and localization validation

Add zh-Hans interface strings and permission descriptions alongside the
adapted English and Traditional Chinese localization framework from
ARahim3/DigUp#34. Cover language fallback, dynamic display values, source
tables and packaged localization resources with regression checks.

Preserve upstream Bundle ID, update feed/key, permissions and dependency
lockfile. Keep fork-only CI outside this feature branch.

+adapts the Traditional Chinese translations with mainland Chinese UI terminology.
+The `Show all` Traditional Chinese string also corrects a duplicated count. The
+previously untranslated `receipt` example is localized in all three languages.
+
+Main does not yet contain that framework. A main-based proposal includes its
+localization-only delta, ported onto `ec28973`; it overlaps with and depends on
+agreement about #34. If #34 merges first, only the language/test additions and the
+small count correction should be retained and rebased. No separate runtime or
+fork-specific app identity is introduced.
+
+## Resources and formatting
+
+`Sources/DigUpLocalization/Resources/{en,zh-Hans,zh-Hant}.lproj` each contain
+`Localizable.strings` (425 keys) and `InfoPlist.strings` (five permission descriptions).
+
+`L10n.text` looks up static interface text. `L10n.format` formats display values with
+positional `%1$@`, `%2$@`, etc. The English format is also the lookup key. Pass
+already formatted strings, for example a count's `.formatted()` value, and escape
+literal percent signs as `%%`. Chinese may omit an English singular/plural noun
+argument, but must preserve counts, paths, times and other display values. Numeric
+duration formats such as `%.1f h` keep their original specifiers.
 
-`L10n.text` looks up static interface text. `L10n.format` formats display values with positional `%1$@`, `%2$@`, etc.
-The English format is also the lookup key. Pass already formatted strings (for example a count's `.formatted()` value),
-and escape a literal percent as `%%` in format strings. Translations may reorder or omit an argument; Chinese need not
-include an English singular/plural noun supplied by the calling code. Keep both English noun forms for existing English
-plural behavior. `String(format:)` duration formats such as `%.1f h` are translated before their existing formatting call.
+Search terms, tokenizer behavior, model prompts, file paths, stored settings keys,
+helper commands and diagnostics are unchanged. Translated sample queries are UI
+examples only. System errors and third-party UI retain their own localization.
 
-To add a language, add its `.lproj` directory with both files and the same interface keys. Keep permission descriptions
-consistent with the English Info.plist. Run `swift test`, build with `./build.sh`, and inspect the packaged app's UI in
-both languages, including long explanatory text and strings with counts, percent signs, and file names.
+`build.sh` embeds `DigUp_DigUpLocalization.bundle` in `Contents/Resources` and copies
+each locale's `InfoPlist.strings` into the main app bundle for macOS permission
+prompts. App name, bundle ID, index location and update feed stay production defaults.
 
-`build.sh` embeds the SwiftPM resource bundle in `Contents/Resources`. It also copies each language's `InfoPlist.strings`
-into the main app bundle so macOS can localize its permission prompts. This step matters: launching from the build
-folder alone does not prove that the distributed `.app` includes its translations.
+## Checks
 
-Search terms, tokenizer behavior, model prompts, file paths, stored settings keys, helper commands and diagnostics are
-not localized. Sample queries shown in the UI may be translated; they are examples, not changes to search processing.
-System error descriptions and third-party UI use the localization supplied by macOS or the dependency.
+Run dependency-free source and packaging-command fixture checks:
 
+```
+python3 scripts/check-localizations.py
+python3 scripts/test-localizations.py
+```
+
+The fixture uses a mock SwiftPM bundle and runs the actual resource-copy block from
+`build.sh`; it is not a real macOS build. Source validation checks unique/nonempty
+keys, exact language-key parity, positional argument types/multiplicity, literal
+percent signs, permission parity and literal UI lookup coverage. Swift tests also
+exercise key fallback and dynamic display values. Region negotiation and runtime
+formatting with positional gaps (such as `%1$@` followed by `%3$@`) are asserted on
+macOS only: Linux swift-corelibs-foundation does not implement Darwin’s language
+negotiation and consumes the wrong argument for positional gaps. Static format
+validation still covers every resource on Linux; this is not a claim of macOS UI
+validation. Test resource lookup accepts SwiftPM’s lowercase locale directories on
+case-sensitive filesystems.
 
-## Origin
+Before publishing a release, on macOS with the documented build dependencies:
+
+```
+swift test
+./build.sh
+python3 scripts/check-localizations.py --app build.noindex/DigUp.app
+codesign --verify --deep --strict build.noindex/DigUp.app
+```
 
-Adapted from [PR #34 by max0071001](https://github.com/ARahim3/DigUp/pull/34), through commit `ef69d2658fbdd5885626ddc68e5e7b12f7523fa7`, onto current main `ec28973`. This is the original author’s localization framework and translations, not newly authored work. Historical screenshots and test counts are omitted because this rebased build has not been validated on macOS.
+Inspect the packaged app in English, `zh-CN`, `zh-Hans`, `zh-TW` and an unsupported
+language such as French. Cover onboarding; search and no results; menus; all
+settings tabs; code search; scheduled indexing; paused/progress states; manual
+model selection and download errors; and long names/counts/percent signs. Check
+Close/Back/Cancel and reopening flows, truncation and accessibility labels. Verify
+permission descriptions in packaged resources and, in an appropriate test account,
+live macOS permission prompts. Do not reuse historical #34 screenshots or test
+counts as evidence that this rebased Simplified Chinese build passed.
