+### Eklendi — Faz 9a: varlık lotları ve kâr/zarar
+
+- Birikim sayfası (`/birikim`): altın, döviz ve ziynet varlıkları (`assets`); toplam güncel değer, toplam maliyet, gerçekleşmemiş ve gerçekleşmiş kâr/zarar; elde kalmayan varlıklar ayrı grupta. Fiyatı olmayan varlık toplam değere katılmaz ve belirtilir.
+- Varlık hareketleri (`assetMovements`): alım, gelen hediye/miras, satış, hediye/çıkış; tarih, miktar, tutar veya birim fiyat (ikisi de boşsa fiyat tablosundan: alımda satış, satış ve hediyede alış fiyatı), hesap, saklama yeri, not. Geçmiş tarihli satış/çıkış o tarihteki miktarla sınırlıdır.
+- Hesap bağlantısı: alım hesaptan varlığa, satış varlıktan hesaba transfer olarak kaydedilir (bakiye değişir, gelir/gider raporlarına girmez). İşlem listesinde varlık adıyla görünür; bağlı işlem tek başına düzenlenemez/silinemez, hareket silinince birlikte silinir.
+- Hesap motoru (`shared/portfolio.ts`): ağırlıklı ortalama maliyet, satışta ortalama maliyetle gerçekleşmiş K/Z, çıkışta K/Z yazılmaz, gelen hediyenin maliyeti o günkü değer (yatırım sayılmaz); güncel değer alış fiyatıyla (Faz 0), gerçekleşmemiş K/Z TL ve %.
+- `/birikim/:id`: özet (eldeki miktar, ortalama maliyet, maliyet, güncel değer, K/Z, yatırılan, satış geliri), hareket geçmişi (kalan miktar, satış K/Z'si), hareket silme (sonraki çıkışı eksiye düşürecekse reddedilir).
+- "Yalnızca ben" varlık: varlık, hareketleri ve bağlı hesap işlemleri yalnızca sahibine görünür.
+- Seed: aylık alımlı ve bir satışlı gram altın birikimi, düğün ziynetleri (hediye giriş ve çıkış), Emre'nin "yalnızca ben" dolar varlığı, Annemler'de fiyatsız bilezikler.
+- `009` migration'ı: `assets`, `assetMovements` index'leri, işlemlerde `assetId`. Denetim kaydı: `asset.delete`, `asset.movement.delete`.
+- Testler: ortalama maliyet, satış/çıkış, hediye, eksi miktar, oran biçimi (birim); alım/satış transferleri ve bakiye, fiyat tablosundan tutar, gerçekleşmiş K/Z, kilitli işlem, hareket silme, gizli varlık, izleyici ve başka hane (entegrasyon).
