+Faz 7: planlı/düzenli işlemler, kredi kartı ve KMH dönemleri, taksitler (7a ve 7b alt fazları).
+
+### Eklendi — Faz 7b: kart ve KMH dönemleri, taksitler
+
+- Dönem hesabı (`shared/card-periods.ts`): kesim günü dahil "Hesap Kesim Dönemi", sonrası "Güncel Dönem"; kesim günü ayda yoksa ayın son günü; kesim günü bitmeden dönem kapanmış sayılmaz. Son ödeme: kesimden N gün sonra veya ayın sabit günü.
+- Kart özeti (`/hesaplar/:id`, kredi kartı): toplam borç, kullanılabilir limit (gelecek taksitler dahil düşülür) ve kullanım çubuğu; hesap kesim dönemi borcu, asgari ödeme, ödenen, kalan, son ödeme tarihi ve kalan gün; güncel dönem harcaması; dönem dönem yaklaşan taksitler; planlı harcamalar; son 6 ekstre.
+- Asgari ödeme: limit 50.000 TL altı %20, üstü %40; kart bazında oran girilebilir (hesap formu).
+- "Borcu öde": ödeme hesabından karta transfer formu kalan dönem borcuyla dolu açılır; ödemeler dönem borcundan düşer (kısmi ödeme desteklenir).
+- Taksitli harcama: kredi kartı giderinde taksit sayısı (2–36). Her taksit ayrı işlem ("Hepsiburada 4/9"); toplam kuruş kaybı olmadan bölünür; vadesi gelen taksit kendi döneminde otomatik gerçekleşir, gelecek taksitler planlıdır ve bakiyeyi etkilemez. Ayrıntıdan "Kalan taksitleri iptal et".
+- KMH özeti (KMH'li banka hesabı): limit, kullanılan, kullanılabilir; geçen ve bu dönem için gün sonu eksi bakiyelerden tahmini faiz; "Faiz kaydı ekle" kesim tarihli, "Banka › Faiz" kategorili gider formunu doldurur (vergiler hariç not).
+- `statements` koleksiyonu: kart/KMH dönem kayıtları (borç, asgari, ödenen, harcama, tahmini faiz); kart özeti okunurken işlemlerden yeniden hesaplanır.
+- İşlem formuna ön doldurma desteği (kart ödemesi, faiz kaydı).
+- Seed: iki taksitli kart alışverişi.
+- `006` migration'ı: `statements` index'leri, taksit planı index'i.
+- Testler: dönem/son ödeme/asgari/taksit planı/KMH faizi (birim); kart özeti tutarlılığı (bağımsız bakiye hesabıyla), ödeme etkisi, taksit üretimi ve otomatik gerçekleşme, taksit iptali, taksit kuralları, KMH faiz tahmini ve yetki (entegrasyon).
+
+### Düzeltildi — Faz 7b
+
+- Seed: aynı aydaki satıcısız/kategorisiz transferler aynı `seedRef`'i aldığı için kart borcu ödemesi ve aylık birikim transferleri hiç oluşmuyordu; artık oluşuyor (mevcut kayıtlar kopyalanmaz). Kart ödemesi son ödeme gününden önceye alındı.
 
 ### Eklendi — Faz 7a: planlı ve düzenli işlemler
