AITURK IDE 1.0.0-beta.17: telefon kodu yayini yeniden denenir

Uzun sure acik kalan IDE'de "Telefon ekle" ilk istegi olu bir keep-alive
baglantisinda kaybedebiliyordu; bulusma kaydi yayinlanamayinca kod yolu bes
dakika boyunca "Kodla baglanma su an kullanilamiyor" kaliyordu (QR calisiyordu).

- publishPairOffer: en cok 4 deneme (0,5 / 1,5 / 3 sn); ag hatasi, 5xx ve 429
  yeniden denenir, 422 kalicidir; yaniti kaybolan denemeden sonraki 409 kaydin
  yerinde oldugu anlamina gelir (iptal jetonu yoktur, kayit kendiliginden biter).
- Pencerede "Yeniden dene": ayni kod ve QR ile kaydi yeniden yayinlar.
- Role oturumu kaydi ve "Giris yap" baslangici icin tek ek deneme (zaman asimi
  yeniden denenmez).
- Gunluge yalniz "pair offer published / failed after N tries" duser; kod,
  lookup ve jeton yazilmaz.

+AITURK Chrome — Windows beta 0.1.0
+
+GEREKSİNİMLER
+Windows 10/11, Chrome 116 veya üzeri, AITURK IDE 1.0.0-beta.7 veya üzeri.
+Eski IDE sürümleri bu eklentiye bağlanamaz. Yerel IDE açık olmalıdır.
+İlk beta yalnızca IDE'nin etkin yerel profilini destekler; uzak sunucu/bulut
+konuşmaları ve başka bilgisayardaki konuşmalar bu sürümde desteklenmez.
+
+KURULUM
+1. ZIP'i kalıcı bir klasöre çıkarın. ZIP içinden doğrudan çalıştırmayın.
+2. AITURK Chrome Kur.exe dosyasını çalıştırın ve bağlantı kurulumunu onaylayın.
+   Yönetici yetkisi istenmez. Dosya henüz kod imzalı değildir; Windows yayıncıyı
+   doğrulayamaz. Paketi yalnızca turkservis.online üzerinden alın ve SHA-256'yı
+   doğrulayın. Kurumsal güvenlik politikanız engelliyorsa yöneticinize danışın.
+3. Chrome'da chrome://extensions sayfasını açın. Geliştirici modunu etkinleştirin.
+   "Paketlenmemiş öğe yükle" ile bu paketin extension klasörünü seçin.
+4. Chrome araç çubuğunda AITURK simgesini sabitleyip tıklayın. IDE'yi açın,
+   gerekirse "Yeniden bağlan"a basın. Üst listeden konuşmanızı seçin.
+
+KULLANIM
+Mesajlar seçilen mevcut konuşmaya gönderilir; ayrı bir chat kopyası oluşturulmaz.
+Model ve araçları IDE yönetir. Gönderim yeni model kullanımı ve ücret doğurabilir.
+İş çalışırken yeni mesaj sıraya alınır. "Durdur" aynı IDE işini de durdurur.
+Araç onayları, ek bilgi soruları ve hassas işlemler IDE'de yanıtlanır.
+Listede son 200 kayıt içindeki IDE konuşmaları; geçmişte son 40 kayıt gösterilir.
+Görüntülenen uzun mesajlar kısaltılabilir. Modelin mevcut bağlamı değiştirilmez.
+"Yenile" konuşma listesini ve seçili geçmişi tekrar okur.
+Ctrl+Enter mesaj gönderir. Enter yeni satır ekler.
+
+SAYFA İÇERİĞİ VE GİZLİLİK
+Eklenti gezinme geçmişini, çerezleri, form değerlerini veya parolaları toplamaz.
+Sayfa/seçim yalnızca "Sayfayı / seçimi ekle" tıklandığında okunur; siz Gönder'e
+basana kadar IDE'ye gönderilmez. URL sorgu/fragment alanları dahil edilmez.
+Görünür sayfada kişisel veya gizli bilgiler varsa bunlar metne dahil olabilir.
+Hassas bilgi içermediğini kontrol edin; eki Kaldır ile silebilirsiniz.
+Sayfa içeriği gönderilince IDE konuşmasına ve seçili model sağlayıcısına gider.
+Eklenti hiçbir API anahtarı saklamaz. Yalnızca son seçili konuşmanın kimliği
+Chrome'un bu bilgisayardaki yerel eklenti deposunda tutulur. Telemetri yoktur.
+
+SORUN GİDERME
+"Native messaging host not found": bağlantı kurulumunu yeniden çalıştırın.
+"IDE bağlantısı bulunamadı": Chrome destekli IDE sürümü açık ve yerel bağlantıda
+olmalıdır. IDE'yi yeniden başlatıp eklentide Yeniden bağlan'a basın.
+"Cannot access contents": ilgili sekmede AITURK araç çubuğu simgesine tıklayın.
+chrome://, Chrome Web Store, PDF görüntüleyici gibi korumalı sayfalar okunamaz.
+Zaman aşımında mesaj otomatik tekrar gönderilmez. Çifte gönderimi önlemek için
+önce IDE geçmişini kontrol edin. Taslağınız panel kapanana kadar korunur.
+
+KALDIRMA
+Eklentiyi chrome://extensions üzerinden kaldırın.
+Bağlantı kaydını kaldırmak için komut satırından:
+  "AITURK Chrome Kur.exe" --uninstall
+Bu işlem yalnızca Chrome bağlantı kaydını kaldırır; konuşmalara dokunmaz.
+Bağlantı dosyalarını isterseniz şu klasörden elle silebilirsiniz:
+  %LOCALAPPDATA%\TurkServis\AITURK-IDE\ChromeNativeHost
+
+Bu ZIP geliştirici modu beta dağıtımıdır; Chrome Web Store yayını değildir.

+# AITURK Chrome beta
+
+Windows / Chrome MV3 side panel for existing local AITURK IDE conversations.
+Requires AITURK IDE 1.0.0-beta.9 or later; see `KURULUM.txt` for Turkish setup.
+
+The extension talks only to `online.turkservis.aiturk` using Chrome native
+messaging. The per-user .NET Framework host authenticates to Electron's random
+named pipe with a separate capability from the user-local discovery file.
+Electron retains the gateway token, allows only six semantic operations and
+reuses the existing local backend. It resumes the stored conversation, maps its
+runtime identity, then submits only the new prompt. No parallel agent backend,
+history reconstruction, model API key in the browser or telemetry is involved.
+
+Only the active local profile is supported. The list searches titles among
+the most recent 200 desktop sessions (two API pages of at most 100, filtered
+server-side before pagination). The transcript shows the last
+40 records, with up to 8,000 characters per visible message; the model's existing
+context is not truncated by this display policy. Approvals and clarifications
+remain in the IDE. A backend event is stamped once and delivered to every
+attached viewer so the desktop can still show and answer these requests.
+
+## Build and verification
+
+From the repository root, on Windows:
+
+```powershell
+./scripts/build-chrome.ps1 -OutputDirectory C:/path/to/new-output-directory
+$env:AITURK_TEST_NATIVE_HOST = 'C:/path/printed/by/build/AITURK Chrome Kur.exe'
+node --test apps/chrome/tests/bridge.test.mjs
+```
+
+The build uses the Windows .NET Framework C# compiler, not a downloaded binary.
+`AITURK_TEST_NATIVE_HOST` enables the real framing / named-pipe / HTTP / WebSocket
+integration test against a disposable fixture, without installing registry
+entries or invoking a paid model. Without it the native host test is skipped.
+
+UI tests require the existing desktop workspace's jsdom dependency:
+
+```powershell
+npm ci --workspace apps/desktop --include-workspace-root
+node --test apps/chrome/tests/panel.test.mjs
+```
+
+Exercise the production FastAPI session router and real temporary SQLite stores
+with the JS bridge (no model requests or user data):
+
+```powershell
+$env:AITURK_TEST_PYTHON = 'C:/path/to/python-with-hermes-dependencies.exe'
+node --test apps/chrome/tests/sessions-api.test.mjs
+```
+
+This contract test reproduces the original 422 for an oversized page, then
+verifies 200 desktop conversations across two valid pages, profile isolation,
+short/empty lists, archived/empty/cron exclusion and bounded pagination.
+
+Run backend fan-out and replay tests with the canonical hermetic runner:
+
+```bash
+scripts/run_tests.sh -j 1 --paths tests/tui_gateway/test_chrome_viewer_fanout.py:tests/test_tui_gateway_event_replay.py
+```
+
+Publish an IDE installer from the same clean commit (including the backend
+change), the Chrome ZIP and their SHA-256 checksums together. Update the download
+page only after the immutable release assets are available. This is an unsigned
+developer-mode beta, not a Chrome Web Store or signed Windows release.

+# macOS yerel menüsünün Türkçe desteği
+
+Dosya, Düzen, Görünüm, Pencere, Yardım ve uygulama menüsündeki komutlar
+Türkçe gösterilir. Ana pencerenin dil seçimi mevcut `display.language`
+ayarından gelir. Dar kapsamlı `setUiLanguage` köprüsü yalnızca menü
+etiketlerini günceller; ayrı bir tercih dosyası veya sunucu ayarı oluşturmaz.
+Dil kaydı başarısız olursa arayüzle birlikte menü dili de geri alınır.
+Yardımcı pencereler ana pencerenin menü dilini değiştiremez.
+
+Menü öğelerinin eylemleri, Electron rolleri ve klavye kısayolları korunur.
+Özellikle renderer tarafından yönetilen yeni pencere, klasör açma, sekme
+kapatma ve sayfa yenileme komutlarına yerel kısayol eklenmez. İngilizce
+seçilince özgün İngilizce şablon kullanılır; diğer diller yerel menüde
+mevcut İngilizce desteğini kullanmaya devam eder.
+
+Paket doğrulama yolları `package.json` içindeki AITURK ürün ve çalıştırılabilir
+dosya adlarını kullanır. Intel Mac için `release/mac`, Apple Silicon için
+`release/mac-arm64` aranır. Temiz kurulum denemesi açıkça izole
+`AITURK_IDE_HOME` ve Electron kullanıcı dizini seçer. Başka bir Hermes
+kurulumunun çalışma dizinine yönelmez.
+
+## Kanıt ve yayın sınırı
+
+- Menü birim testleri eylem, rol ve kısayol bütünlüğünü; kaynak pencere ve
+  dil doğrulamasını kontrol eder.
+- React testi yüklenen dil, iyimser geçiş ve kayıt hatasında geri dönüşün
+  yerel köprüye iletildiğini doğrular.
+- Gerçek Electron E2E testi köprüyü kullanır. macOS'ta yerel menü etiketlerini,
+  Windows'ta uygulama menüsünün kapalı kalmasını kontrol eder.
+- Windows üzerinde Türkçe ayar kaydı ve köprü testleri geçti. Paket yolu,
+  mevcut Windows beta.5 dosyası üzerinde açılış ve içerik kontrolüyle doğrulandı.
+
+Bu kaynak değişikliği, yayımlanan Windows beta.5 dosyasını değiştirmez.
+macOS dalındaki E2E testi, DMG/ZIP derlemesi ve gerçek Mac'te çalıştırma henüz
+doğrulanmadı. Mac paketi bu kanıtlar tamamlanmadan yayımlanmış sayılmaz.

+# AITURK IDE 1.0.0-beta.5 — Türkçe dil kapsamı
+
+Türkçe dil desteği, menü başlıklarından ayar alanlarının açıklamalarına,
+seçeneklerine, doğrulama ve işlem sonuçlarına genişletildi. Gelişmiş bağlantı,
+yerel model, bilgisayar kullanımı, araç, bellek, profil, mesajlaşma ve görev
+ayarları Türkçe metinler sunar. Faturalandırma ekranındaki planlar, tutar
+doğrulamaları, otomatik yükleme ve ödeme hataları da dil seçimine uyar.
+
+Sohbet filtreleri, zaman çizelgesi, bellek/beceri işlemleri, görsel üretim
+kurulumu, Bots ve Kanban eklentileri Türkçe kapsamına alındı. Hızlı giriş ve
+masaüstü maskotu ana pencerenin dil seçimini mevcut IPC durum aktarımıyla
+izler; ayrı bir sunucu bağlantısı veya ayar yazıcısı oluşturmaz.
+
+Çeviri yalnızca sunum metinlerini değiştirir. Model ve sağlayıcı kimlikleri,
+özel profil/proje adları, API alanları, ayar enum değerleri, oturum hedefleri,
+ödeme tutarları ve idempotency davranışı korunur. Harici sağlayıcının kendi
+hata mesajları ve kullanıcı tarafından eklenmiş açıklamalar değiştirilmez.
+
+## Doğrulama
+
+- Türkçe sözlük, İngilizceye geri düşmeden tüm kayıtlı çekirdek mesaj
+  anahtarlarını ve ayar alanlarının etiket/açıklamalarını kapsar.
+- Arayüz testleri Türkçe seçeneklerin özgün API değerlerini kaydettiğini,
+  ödeme tutarlarının değişmediğini ve dil geçişinde hızlı giriş taslağı ile
+  hedef oturum kimliğinin korunduğunu kontrol eder.
+- Gerçek Electron uygulamasında güvenlik ayarındaki “Elle onayla” seçeneği
+  masaüstü köprüsünden kaydedilir; API cevabı ve izole kullanıcı dizinindeki
+  YAML dosyasında `approvals.mode: manual` doğrulanır.
+- Paket doğrulaması, temiz kaynak commit'ini içeren `install-stamp.json`,
+  Windows kurulum dosyasının SHA-256 değeri ve indirilen dosyanın eşleşmesiyle
+  tamamlanmalıdır. Bir derlemenin varlığı, yayımlandığı anlamına gelmez.
+
+## Platform durumu
+
+Windows paketi önceki beta sürümünden ayrı, değiştirilmeyen bir yayın varlığı
+olarak hazırlanır. Windows Authenticode imzası yoksa yayın notunda açıkça
+belirtilir; dosya özeti yayıncı imzası olarak sunulmaz.
+
+macOS için Apple Silicon ve Intel derleme komutları ile Türkçe sistem izin
+metinleri eklendi. Gerçek macOS derleme/çalıştırma ve varsa Apple imzalama/
+notarizasyon doğrulaması tamamlanmadan Mac paketi hazır olarak duyurulmaz.
+
+CLI 1.10.24 ayrı bir üründür ve bu IDE sürümünün yayınlanması CLI'nin imzalı
+yayın kontrolünü karşılamaz.

+/**
+ * aiturk-login.ts
+ *
+ * One-click TurkServis sign-in for AITURK IDE (device-code flow).
+ *
+ * The IDE shows a short code, the browser opens the turkservis.online approval
+ * page, and once the user approves, the server hands out two API keys exactly
+ * once: one for the IDE's TurkServis provider and one for the AITURK CLI.
+ *
+ * Security contract (do not relax):
+ *   - Keys (`tsk_…`) and the device code (`tsdl_…`) never leave the main
+ *     process: they are not returned to the renderer, not logged, not put into
+ *     error messages, process arguments or URLs.
+ *   - The CLI receives its key on stdin only, is launched from an absolute
+ *     path without a shell, with a fixed argument list.
+ *   - Network calls go only to https://turkservis.online, refuse redirects and
+ *     time out after 20 s.
+ *
+ * All I/O is injected so the logic is unit-testable without Electron, a
+ * network or a real CLI (see aiturk-login.test.ts).

+ * "Telefon bağlantısı" through the turkservis.online tunnel (contract:
+ * workspace/aiturk-mobil-tunel-spec.md, v3). The IDE opens ONE outbound
+ * WebSocket to the gateway. For every phone stream the gateway announces
+ * (`open`), this client opens a PLAIN TCP connection to this IDE's own TLS
+ * proxy on loopback (electron/mobile-lan-proxy.ts) and copies bytes both ways.
+ *
+ * It never terminates TLS and never looks at a byte: the TLS session is
+ * between the phone (which pins the proxy's certificate) and the proxy. So the
+ * gateway — and this file — only ever carry ciphertext, and every rule (device
+ * token, forbidden list, root 404, WebSocket path list) stays in the proxy.
+ *
+ * Security contract (do not relax):
+ *   - `hostToken` (`tsmr_…`) lives only in the injected credential store (the
+ *     controller keeps it in the safeStorage vault). It is sent in the
+ *     `Authorization` header of the host WebSocket and nowhere else: not in a
+ *     log line, a status object or an error message.
+ *   - Log lines are status changes only.
+ *   - Errors are fixed codes.
+ *
+ * Everything that touches the outside is injected (WebSocket connector, fetch,
+ * local TCP dial, timers, credential store) so the tests run against a fake
+ * relay on 127.0.0.1 and a fake clock.
