Summary

Adds Turkish as a learning language option. This is not a UI translation — it adds the Turkish learning module itself (teaching policy, theme overrides, greeting logic) plus the platform registrations needed to expose it.

Changes

  • Turkish.swift: learning language module with 6 teaching-focus levels and 5 theme overrides, following the same structure as Spanish.swift / Norwegian.swift
  • Registered Turkish in LanguageRegistry.all and MeaningLanguages
  • Languages.kt: Android-side export so the module is available cross-platform
  • 9 unit tests covering the new module
  • Fixed UTF-8 encoding in export_android_content.py and check_cross_platform.py (read_text()read_text(encoding='utf-8')) — Python's default encoding on Turkish Windows is cp1254, which broke reading Unicode content. No-op on macOS/Linux, included here rather than as a separate PR since it's what let the cross-platform check pass for this module.

Teaching progression

Level Focus
0 Greetings, introductions and useful everyday chunks
1 Everyday questions, vowel harmony, present tense
2 Connected stories, past tense (miş/mış and di/di), future tense
3 Reasons and opinions, conditional clauses, reported speech
4 Nuance, hypothetical situations, passive and causal constructions
5 Flexible advanced discussion with precise, natural Turkish

Testing

  • check_cross_platform.py and export_android_content.py both pass cleanly, including for all existing languages (not just Turkish) — confirms the encoding fix doesn't affect other locales
  • Not tested: iOS build/runtime, since I'm on Windows without Xcode. Turkish.swift follows the same LanguageModule struct pattern as existing modules, but this hasn't been compiled or run

Limitations

  • Real device voice check not performed — tested on Android emulator only
  • iOS build and real-device voice check were unavailable on the development machine (Windows). Android was verified with emulator testing. The iOS changes follow the same patterns as Android and should be verified on a Mac before merge.

Checklist for maintainers

  • Verify iOS build compiles with the new module (not testable on Windows)
  • Verify voice behavior on a real Android device
  • UTF-8 fix is safe — verified against all languages, no effect on non-Windows environments
  • Teaching-focus levels and theme overrides reviewed for Turkish (see table above)
  • No unrelated files — git diff shows exactly 6 files, all relevant

- Add Turkish learning language module (id: tr, locale: tr-TR)
- Register Turkish in LanguageRegistry.all
- Add Turkish as meaning language option with greeting
- Export Turkish content to Android Languages.kt
- Add 9 Turkish-specific tests (registration, curriculum, progress isolation, archive roundtrip, hidden words, teaching policy, meaning greeting, meaning support)
- Fix UTF-8 encoding in export and cross-platform scripts

In `@apps/ios/Core/Languages/Turkish.swift`:
- Line 8: Update the Turkish writingGuidance case-pair list in the iOS Turkish
configuration and the Android Turkish configuration to use I/ı, İ/i, Ş/ş, Ç/ç,
Ğ/ğ, Ö/ö, Ü/ü, removing duplicated lowercase entries while preserving the
existing guidance.

In `@apps/ios/Tests/LanguageTests.swift`:
- Line 250: Update the assertion in the language test to compare the resolved
theme IDs from turkish.themes with ConversationTheme.shared IDs, or otherwise
assert the five expected override IDs, instead of comparing
turkish.themeOverrides.keys to all shared theme IDs.
- Line 259: Update the language projection test around spanishSessions and its
projection assertions so it no longer expects an empty Spanish projection after
adding Spanish evidence. Either project a language with no sessions or assert
the expected observation and word values for the Spanish session, while
preserving the intended coverage of the test.
- Line 288: Add a Norwegian-language session to the test data before the
LearningEngine.project call, while retaining the Turkish session and hiddenWords
entry. Ensure the Norwegian assertion receives Norwegian evidence and verifies
that hiding the Turkish key does not remove it.
