+# Faz 7 — AI, chat ve business backend geçişi
+
+Tamamlanma tarihi: 2026-07-17
+
+## Kapsam ve envanter
+
+Faz 7 mevcut sayfa tasarımlarını değiştirmeden aşağıdaki aktif runtime yüzeylerini SQLite, Better Auth ve ortak service katmanına taşır:
+
+- `/chat` client sayfası ve `/api/chat`
+- `/api/finance-analysis`
+- `/api/project-risk`
+- `/business/proposals`
+- `/business/invoices`
+- `/business/subscriptions`
+- `proposals`, `contracts`, `invoices` ve `subscriptions` için domain backend sözleşmeleri
+
+Geçiş öncesinde chat sayfası browser-side Supabase auth ve tablo çağrıları yapıyordu. Üç AI route'u Supabase Auth, `app_settings` ve domain tablolarına doğrudan erişiyor; provider oluşturma mantığını tekrarlıyordu. Aktif business sayfaları da Supabase Server Client ile doğrudan tablo okuyordu.
+
+Repo içinde aktif bir sözleşme sayfası bulunmadığından bu faz yeni bir route veya tasarım üretmedi. Sözleşme backend'i diğer business kaynaklarıyla aynı owner-scoped CRUD seviyesinde tamamlandı. Yeni business form/CRUD UX'i, kilitlenen ürün kararına uygun biçimde Faz 10'a bırakıldı.
+
+## Chat veri sınırı
+
+Chat session ve message işlemleri `DomainService` üzerinden yürür:
+
+- session listeleme, oluşturma, sahiplik doğrulama ve silme
+- message listeleme ve ekleme
+- session silindiğinde SQLite foreign key ile message cascade
+- foreign owner ve client rolü için kaynak varlığını sızdırmayan hata
+
+Chat sayfası artık Supabase client oluşturmaz. Server Action'lar Better Auth freelancer session'ından actor üretir ve domain service'i çağırır.
+
+`/api/chat` istemciden gelen geçmişi güvenilir bağlam olarak kullanmaz. İstek yalnızca sahipliği doğrulanmış `sessionId` ve son kullanıcı mesajı için kabul edilir; model geçmişi SQLite'taki son 40 owner-scoped mesajdan yeniden kurulur. Böylece başka session geçmişi, sahte system message veya browser kaynaklı provider ayarı modele taşınamaz.
+
+Geçerli AI runtime ayarı ve session sahipliği doğrulanmadan mesaj yazılmaz. Başarılı stream başlangıcında kullanıcı mesajı; başarılı model tamamlanmasında assistant mesajı kalıcılaştırılır.
+
+## Server-only AI katmanı
+
+Ortak AI sınırı üç parçaya ayrıldı:
+
+- `server/ai/provider.ts`: encrypted owner ayarını açar, provider/model üretir ve timeout sözleşmesini uygular.
+- `server/ai/context.ts`: yalnızca domain service'in owner-scoped okumalarıyla sınırlı AI bağlamları üretir.
+- `server/ai/responses.ts`: provider/configuration hatalarını kontrollü HTTP hata sözleşmesine çevirir.
+
+Cloud provider API key'i yalnızca `getAiRuntimeSettings` içinden server-side çözülür. Chat request body, client component ve public settings çıktısı key veya provider override taşımaz.
+
+Desteklenen provider yolları:
+
+| Provider | Key | Runtime |
+| --- | --- | --- |
+| Gemini | zorunlu | `@ai-sdk/google` |
+| OpenAI | zorunlu | `@ai-sdk/openai` |
+| Groq | zorunlu | `@ai-sdk/groq` |
+| Ollama | gereksiz | OpenAI-compatible local endpoint |
+
+Ollama endpoint'i `OLLAMA_BASE_URL`, provider timeout'u `AI_REQUEST_TIMEOUT_MS` ile server environment'tan ayarlanabilir. Timeout sınırı 1–120 saniye, varsayılan 30 saniyedir.
+
+Provider kaynaklı ham hata veya secret istemciye dönmez. Configuration hataları `400`, provider bağlantı hataları `502`, timeout `504` olarak normalize edilir. Chat stream başladıktan sonraki provider hatası kullanıcıya sabit ve secretsız bir mesaj verir.
+
+## Context builder
+
+Context builder route içine gömülü sorgu çalıştırmaz. Aşağıdaki domain service okumalarını kullanır:
+
+- son görevler
+- son projeler ve owner'a ait müşteri adları
+- son 30 gün finans kayıtları
+- son 30 gün günlük kayıtları
+- seçili proje için owner-scoped proje ve görevler
+
+Bağlam kayıt adetleri ve toplam karakter sayısıyla sınırlandırılır. Finans toplamları farklı para birimlerini birbirine eklemez; currency bazında hesaplanır. Project risk isteğindeki `projectId` owner kapsamı dışında ise `404` döner. Kayıt içeriği model system prompt'unda veri olarak işaretlenir ve talimat olarak uygulanmaması istenir.
+
+## Finans ve proje risk route'ları
+
+İki route da:
+
+1. Better Auth session'ını request header'ından doğrular.
+2. Freelancer rolü dışındaki actor'ları reddeder.
+3. Domain verisini owner-scoped context builder'dan alır.
+4. Provider ve API key'i encrypted server ayarından çözer.
+5. Ortak timeout ve hata sözleşmesiyle AI SDK çağrısı yapar.
+
+Finans ekranının mevcut `{ text }` başarı sözleşmesi ve proje ekranının `{ projectId }` request sözleşmesi korunmuştur. Finans kaydı yoksa provider çağrısı yapılmadan açıklayıcı sonuç döner.
+
+## Business backend
+
+Teklif, sözleşme, fatura ve abonelik repository/service'leri şu işlemleri owner scope zorunlu olacak şekilde destekler:
+
+- list/get
+- create
+- partial update
+- delete
+
+Teklif ve fatura client/project ilişkileri mevcut domain invariant kontrollerinden geçer. Sözleşme tarafında client ve teklif aynı owner'a ait olmalı; müşterili tekliften üretilen sözleşmenin client bağı teklif ile uyuşmalıdır. Business update işlemleri `updated_at` değerini yeniler.
+
+Aktif teklif, fatura ve abonelik sayfaları Better Auth freelancer adapter'ından domain service'e bağlanır. Para alanları SQLite integer minor unit'ten mevcut UI'ın major unit sözleşmesine çevrilir; tarih değerleri client component'e serializable biçimde aktarılır.
+
+## Güvenlik ve test kapsamı
+
+`phase7:backend-boundary` aşağıdakileri denetler:
+
+- Faz 7 runtime dosyalarında Supabase import/reference bulunmaması
+- runtime Supabase environment bağı bulunmaması
+- browser `localStorage` kullanımı bulunmaması
+- AI route'larının request body'den key/provider seçmemesi
+- chat client bundle'ında key/provider bulunmaması
+- legacy Supabase embeddings helper'ının aktif runtime tarafından import edilmemesi
+
+`phase7:domain-smoke` temiz migration uygulanmış SQLite üzerinde şunları doğrular:
+
+- chat session/message sahipliği ve cascade delete
+- AI context'lerinde cross-owner veri izolasyonu
+- foreign project risk erişiminin reddi
+- dört business kaynağında CRUD, client rol reddi ve cross-owner negatifleri
+
+Better Auth HTTP smoke testi ayrıca:
+
+- `/chat` ve aktif business sayfalarının authenticated SSR yanıtını
+- anonim AI route reddini
+- API key bulunmayan kontrollü AI configuration hatasını
+- reddedilen chat isteğinin message yazmamasını
+- SSR çıktısında Supabase izi bulunmamasını
+
+doğrular.
+
+Targeted Faz 7 ESLint, typecheck, production build ve `git diff --check` başarılıdır. Repo genel lint'i Faz 7 dışındaki mevcut client-component borçları nedeniyle başarısız kalır; master plandaki genel lint checkbox'ı bu nedenle işaretlenmemiştir.
+
+## Bilinçli olarak Faz 8/10'a bırakılanlar
+
+- Kullanılmayan `lib/ai/embeddings.ts` aktif runtime tarafından import edilmez; Supabase package ve legacy dosya temizliği Faz 8 kapsamındadır.
+- Supabase production export'undan chat/business veri import'u Faz 8 import aracının parçasıdır.
+- Business create/edit/delete ekranları ve chat/business görsel revizyonları Faz 10'da kullanıcı yönlendirmesiyle ele alınacaktır.
+- Provider model seçimi için yeni UX bu backend fazında eklenmemiştir.
