Localized file check-in by OneLocBuild Task: Build definition ID 679: Build ID 2994210

[dotnet-bot]

This is the pull request automatically created by the OneLocBuild task in the build process to check-in localized files generated based upon translation source files (.lcl files) handed-back from the downstream localization pipeline. If there are issues in translations, visit https://aka.ms/icxLocBug and log bugs for fixes. The OneLocBuild wiki is https://aka.ms/onelocbuild and the localization process in general is documented at https://aka.ms/AllAboutLoc.

🤖 Copilot Code Review — PR #128945

Holistic Assessment

Motivation: Routine automated localization check-in by OneLocBuild. New resource strings for open generic polymorphism diagnostics were added to Strings.resx on main, and this PR propagates placeholder entries to all 13 language-specific XLF files.

Approach: Standard OneLocBuild pipeline — adds <trans-unit> entries with state="new" and English source text as placeholder targets until translators provide actual translations.

Summary: ✅ LGTM. All 13 XLF files receive identical new entries that match the source Strings.resx. No code logic, no new public API, no behavior changes.

---

Detailed Findings

✅ Source String Consistency — Verified

All 7 new trans-unit entries across all 13 language files have <source> text that exactly matches the corresponding <data> entries in src/libraries/System.Text.Json/gen/Resources/Strings.resx on main:

• OpenGenericDerivedTypeCouldNotBeResolvedMessageFormat
• OpenGenericDerivedTypeCouldNotBeResolvedTitle
• Polymorphism_OpenGeneric_Reason_AmbiguousMatch
• Polymorphism_OpenGeneric_Reason_ConstraintViolation
• Polymorphism_OpenGeneric_Reason_NotAssignable
• Polymorphism_OpenGeneric_Reason_UnboundParameter
• Polymorphism_OpenGeneric_Reason_UnificationFailed

✅ Translation State — Correct

All new entries use target state="new" with English placeholder text. This is the expected state for untranslated strings awaiting the localization pipeline.

✅ File Coverage — Complete

All 13 supported languages are updated: cs, de, es, fr, it, ja, ko, pl, pt-BR, ru, tr, zh-Hans, zh-Hant.

💡 Entry Ordering — Minor Observation (Non-blocking)

OpenGenericDerivedTypeCouldNotBeResolvedTitle is placed after the Polymorphism_OpenGeneric_* entries rather than adjacent to OpenGenericDerivedTypeCouldNotBeResolvedMessageFormat. This is determined by the OneLocBuild automation and does not affect functionality (XLF uses id attributes for lookup, not position).
