+The modules teach Norwegian Bokmål with an Eastern Norwegian voice target, Spanish from Spain, international English, French from France, German from Germany, Italian from Italy, Brazilian Portuguese, Standard Mandarin with Simplified Chinese and Afrikaans from South Africa. Each language has its own conversation themes, teaching guidance and progress. Valid regional alternatives are accepted.
 
 On iPhone, Mandarin includes optional pinyin in Talk, transcripts and word details. Chinese word lookup uses word boundaries, and the original characters remain available for copying from transcripts. Pinyin uses system dictionary readings; names, ambiguous words and tone changes in connected speech still need listening checks. Voice accent and teaching guidance are model instructions, and fluent-speaker review is still needed before making pronunciation or learning-effectiveness claims.

 These locales describe the initial teaching targets. Modules accept valid regional usage from learners. Regional pronunciation is a model instruction and still needs listening checks. Portuguese's stable `pt` storage ID currently belongs to the Brazilian module; a future independently selectable variety must not silently reinterpret existing progress.
 
+Apple's language recognizer has no Afrikaans class and labels Afrikaans transcripts as Dutch. The Afrikaans module therefore lists `nl` in `detectorAliases`, which `TeachingPolicy.detectedMatchesTarget` treats as the target so that a learner speaking Afrikaans is never redirected; the voice prompt separately instructs the model not to drift into Dutch.
+
 `TeachingPolicy` combines a module with the shared teaching rules. Voice, assessment, typed replies, help, word lookup, subtitles and current-topic search all use that policy. The audio transport and provider connection remain shared. A module can override selected theme IDs while inheriting the common conversation catalog.
 
 Switching is allowed between conversations. It clears the current screen context and invalidates pending language-dependent work. Previous messages and sourced topic briefs are selected only from the active language. Learner replies can use a support language; the meaning-subtitle language is a separate preference. Vocabulary senses remain in English to keep glossary identities stable.

 After the owner unlocked the phone, the final build launched normally at 16:37:51 CEST. Its running process was confirmed. This reopened the persistent learning store without verification arguments.
 
 The device results verify the application/provider paths with synthetic typed input and real voice output. They do not verify recognition of a human speaker, pronunciation, tones, correction quality, unscripted interruptions, headphones or cellular operation. The proficient-speaker checks requested in issues #10–#13 remain open. Pinyin uses dictionary tones and may need correction for names, ambiguous words and connected-speech tone changes. The Android contribution is not integrated in this checkout, so there is no generated Android language catalog to update here.

+## Afrikaans
+
+14 September 2026
+
+Afrikaans from South Africa (`af`, locale `af-ZA`) joins the registry with its own greeting, speech, writing and lemma guidance, six teaching stages and five South African theme overrides. Apple's language recognizer has no Afrikaans class and labels Afrikaans transcripts as Dutch, so `LanguageModule` gains an optional `detectorAliases` list and `TeachingPolicy.detectedMatchesTarget` treats `nl` as the target for Afrikaans; the voice prompt separately instructs the model not to drift into Dutch. Afrikaans is also available as a subtitle language.
+
+- **72 core tests passed** with Xcode 26.5, including registry order, locale and greeting for `af`, prompt isolation, archive round trips across nine languages, Dutch detector IDs never triggering a redirect, and `'n` apostrophe word links.
+- **2 native UI tests passed** on an iPhone 17 simulator running iOS 26.5: Afrikaans onboarding, and selecting Afrikaans in Settings, checking its greeting and coffee theme, opening Words and returning to Norwegian.
+- The **server locale test passed** with `af-ZA` accepted and bare `af` and `nl-NL` rejected.
+- The signed device build was installed over the existing app on an iPhone 15 Pro Max running iOS 26.5.2 and launched.
+- The owner held a live Afrikaans conversation on the iPhone with a saved key and reported that speech, replies and subtitles worked well.
+- Android receives the module through `scripts/export_android_content.py`, which now also exports the optional `detectorAliases` field, and Kotlin's `TeachingPolicy.shouldRedirectSpeech` honours aliases and regional suffixes like Swift. The exporter's 9 tests, all 50 script tests and the cross-platform prompt check passed. The Android unit tests, including the new Afrikaans registry and redirect checks, were not run locally because this Mac has no Java runtime; CI runs them.
+- OpenAI does not publish a GPT-Live language list and does not name Afrikaans; its guidance is that languages outside the most popular ones may have a non-native accent or gaps in fluency. The automated `--verify-audio --verify-language-flow --verify-language=af` run and a fluent-speaker review of accent, corrections and Dutch drift are still required before making any teaching claim.
