+
+Faz 8: cari hesaplar ve aynî borç/alacak (8a ve 8b alt fazları).
+
+### Eklendi — Faz 8b: aynî borç/alacak ve fiyat tablosu
+
+- Varlık türleri: gram altın, çeyrek, yarım, tam, Cumhuriyet altını, 22 ayar bilezik, gümüş, USD, EUR, GBP (birim: gr / adet / birim; miktarlar binde bir hassasiyetle).
+- Fiyat tablosu (`/fiyatlar`, `assetPrices`): varlık × tarih × alış/satış, elle giriş; tek fiyat girilirse ikisine de yazılır; gün başına tek kayıt; son fiyatlar ve geçmiş. Faz 9 varlık takibi aynı tabloyu kullanacak.
+- Aynî borç/alacak (`inKindDebts`), cari sayfasında: cari, yön (ben borçluyum / bana borçlu), varlık, miktar, borç tarihi; o tarihteki birim fiyat ve TL karşılığı not olarak saklanır (boşsa fiyat tablosundan). Değerleme: borç satış, alacak alış fiyatıyla.
+- Borca bağlı birikim planı: birikim hesabı ve aylık tutar; "Birikim ekle" kaynak hesaptan birikim hesabına transfer oluşturur, borç kapanmaz. Kartta güncel değer, biriken, kalan ihtiyaç ve tahmini kapanış ayı.
+- "Ödeme gerçekleşti": aynı varlıkla veya TL karşılığıyla; tarih, miktar/tutar, hesap. TL ödemede miktar boşsa güncel fiyattan hesaplanır; kısmi ödeme miktarı düşürür, kalanı aşan ödeme kalana sınırlanır, tam ödemede kayıt kapanır. Borç ödemesi hesaptan çıkış, alacak tahsilatı hesaba giriş işlemi olarak aynı transaction'da oluşturulur; denetim kaydı (`inkind.payment`, `inkind.close`).
+- Cari listesinde açık aynî kayıtlar rozet olarak.
+- Aynî borç hareketleri cari TL bakiyesine ve gelir/gider toplamlarına girmez; "yalnızca ben" carinin aynî kayıtları ve hareketleri başkasına görünmez (hesap ekstresinde ad ve açıklama gizlenir). Ödeme işlemi tek başına silinemez.
+- Seed: son 6 ayın örnek altın/döviz fiyatları (gerçek piyasa verisi değildir), birikim planlı 5 gr altın borcu (iki katkıyla), USD alacağı, Annemler'de çeyrek altın alacağı.
+- `008` migration'ı: `assetPrices`, `inKindDebts` index'leri, işlemlerde aynî borç alanları.
+- Testler: değer/miktar karşılığı, değerleme fiyatı, ilerleme ve tahmini kapanış (birim); fiyat tablosu, tarih fiyatı, birikim katkısı, kısmi/tam ödeme, kapanış, alacak tahsilatı, cari bakiye ve gelir/gider ayrımı, gizli cari ve yetki (entegrasyon).
+
+### Eklendi — Faz 8a: cari hesaplar
+
+- Cari kişiler (`contacts`): ad, yakınlık, telefon, not, açılış bakiyesi (+ bana borçlu / − ben borçluyum), vade tarihi ve hatırlatma günü; arşivleme; aynı adda iki aktif cari engellenir (Türkçe normalize).
+- "Yalnızca ben" cari: kişi ve hareketleri yalnızca sahibine görünür; ortak hesabın ekstresinde bu hareketler görünür ama kişi adı "Gizli cari" olarak maskelenir.
+- Cari hareketleri: "Borç verdim", "Borç ödedim" (hesaptan cariye), "Borç aldım", "Tahsilat" (cariden hesaba). Hepsi transferdir: hesap bakiyesi değişir, gelir/gider toplamlarına girmez. Kısmi ödeme bakiyeyle doğal olarak desteklenir.
+- `/cari`: bana borçlu / ben borçluyum / net özeti, cari listesi (bakiye, son hareket, vade rozeti), yeni cari, hareket ekle, düzenle, arşivle.
+- `/cari/:id`: cari ekstresi (tarih sıralı hareketler ve yürüyen bakiye, açılış satırı); hareketi düzenleme ve geri alınabilir silme.
+- Vade uyarısı (uygulama içi): vade geçtiyse veya hatırlatma penceresindeyse cari listesinde rozet ve dashboard'da uyarı.
+- İşlem listesi ve ayrıntısında cari hareketleri kişi adı ve hareket türüyle; ayrıntıdan cariye bağlantı. CSV'de kategori sütununda "Cari: Ad (tür)".
+- Seed: 5 örnek cari (vadesi yaklaşan alacak, kısmen ödenen borç, vadesi geçmiş alacak, "yalnızca ben" cari, Annemler hanesinde bir borç).
+- `007` migration'ı: `contacts` index'leri, işlemlerde cari alanları. Denetim kaydı: cari arşivleme.
+- Testler: yön/bakiye ve vade durumu (birim); defter, bakiye ve gelir/gider ayrımı, açılış bakiyesi, ekstre, tür değiştirme, vade uyarısı, çift ad, arşiv, yetki, başka hanenin hesabı ve gizli cari izolasyonu (entegrasyon).
+
+### Değişti — Faz 8a
+
+- İşlemlerde kaynak hesap (`accountId`) artık boş olabilir: cariden girişte para yalnızca hedef hesaba (`toAccountId`) girer. Bakiye, ekstre, kart ve KMH hesapları ek kural olmadan doğru çalışır.
+
+## [0.7.0] - 2026-11-05
+
+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
+
+- Düzenli işlem kuralları (`recurringRules`): gelir, gider, transfer; sabit veya tahmini tutar; günlük/haftalık/aylık/yıllık, "her N birimde bir", ayın N. günü (ayda yoksa son gün) veya ayın son günü; bitiş yok, tekrar sayısı (ör. 12) veya bitiş tarihi. Formda Türkçe tekrar açıklaması ve ilk tarihlerin önizlemesi.
+- Her tekrar için `planned` durumunda planlı kayıt; bitiş tarihsiz kurallarda 12 ay ileriye kadar. Ufuk sayfa okunurken ilerletilir (zamanlanmış görev gerekmez); üretim idempotent (`recurringRuleId + occurrenceIndex` benzersiz). Planlı kayıtlar bakiyeyi etkilemez.
+- `/planli`: vadesi geçmiş, yaklaşan (60 gün) ve kurallar sekmeleri; "Onayla" (tutar ve tarih düzeltilebilir), "Ertele", "Atla"; seri pozisyonu ("3/12") ve "Tahmini" rozetleri.
+- Seri düzenleme: "Yalnızca bu" (kayıt seriden ayrılır), "Bu ve sonrakiler" (seri bölünür), "Tümü" (onaylanmamış planlı kayıtlar yeniden üretilir; gerçekleşen, atlanan ve ayrılmış kayıtlar korunur). Silmede "bu ve sonrakiler" / "tüm seri"; gerçekleşmiş kayıtlar silinmez.
+- Dashboard'da vadesi geçmiş planlı işlem uyarısı.
+- Seed: 11 örnek düzenli işlem (maaş, kira, aidat, tahmini faturalar, abonelikler, emekli maaşı; vadesi geçmiş örnek olarak 12 taksitli spor salonu).
+- `005` migration'ı: `recurringRules` index'leri, işlemlerde tekrar alanları. Denetim kaydı: `recurring.delete`.
+- Testler: tekrar tarihi hesabı (ay sonu, artık yıl, aralık, sayı/bitiş/ufuk) ve form şeması (birim); üretim, onay/atla/ertele, seri düzenleme ve silme, bakiye etkisizliği, yetki ve gizli hesap izolasyonu (entegrasyon).
+
+### Değişti — Faz 7a
+
+- İşlem listesi varsayılan olarak planlı kayıtları göstermez (durum filtresiyle görülebilir); özet toplamları seçili duruma göre hesaplanır.
+
+## [0.6.0] - 2026-11-05
+
+Faz 6: hesaplar, kategoriler, işlemler, ek dosyalar ve mutabakat (6a, 6b, 6c alt fazları).
+
+### Eklendi — Faz 6c: ek dosyalar, carousel, ekstre ve mutabakat
+
+- Depolama soyutlaması `lib/storage/` (`put`, `get`, `delete`); yerel disk sürücüsü (`UPLOAD_DIR`), atomik yazma, rastgele anahtarlar, yol geçişine karşı anahtar doğrulaması.
+- Ek dosya yükleme `POST /api/files`: tür dosya içeriğinden (imza) tespit edilir — JPEG, PNG, WebP, HEIC, PDF; uzantıya güvenilmez. Dosya başına `MAX_UPLOAD_MB` (10 MB), kayıt başına 10 dosya. Origin kontrolü.
+- Görseller sharp ile EXIF yönüne göre döndürülür, en fazla 2000 px'e küçültülür, WebP'ye çevrilir; EXIF/GPS dahil tüm meta veri silinir; 320 px küçük resim üretilir. iPhone HEIC dosyaları libheif (WASM, `heic-decode`) ile çözülür. PDF'ler yapı kontrolünden sonra olduğu gibi saklanır.
+- Yetkili servis `GET /api/files/:id` (`?v=thumb`, `&indir=1`): oturum + hane üyeliği; bekleyen ek yalnızca yükleyene; silinmiş işlemin veya başkasının gizli hesabındaki işlemin eki görünmez (404). Dosyalara özel sıkı CSP, `nosniff`, `private` önbellek.
+- `attachments` koleksiyonu (`ownerType`, `ownerId`, tür, boyut, yükleyen, sıra). Ekler işlemle aynı MongoDB transaction'ında bağlanır; hata olursa işlem de oluşmaz. Gider: yalnızca görsel; gelir ve transfer: görsel veya PDF.
+- İşlem formunda küçük "Ek ekle" alanı (çoklu seçim, yükleme göstergesi, küçük önizleme, kaldırma, sayaç); yüklemeler bitmeden kaydedilemez. Kopyada ekler taşınmaz.
+- Görüntüleyici: shadcn Carousel (Embla) — oklar, kaydırma, klavye okları, tam ekran, "2 / 5" göstergesi, indirme; PDF'ler ikon + "Aç" düğmesiyle. Ayrıntıda en fazla 4 küçük resim + "+N".
+- Temizlik `npm run cleanup`: 24 saatten eski bağlanmamış ekler, 30 günden önce kayıttan çıkarılmış ekler ve 30 günden önce silinmiş işlemlerin ekleri (dosyalarıyla) silinir.
+- Hesap ekstresi `/hesaplar/:id?ay=YYYY-MM`: ay başı/ay sonu bakiyesi, giriş/çıkış, yürüyen bakiye, mutabakat işaretleri; işlem ayrıntısı ekstreden açılır. Başkasının gizli hesabına transfer ekstrede görünür ama karşı hesap adı gizlenir.
+- Mutabakat: ekstre tarihi ve bakiyesi girilir, uygulama bakiyesiyle karşılaştırılır (kredi kartında borç pozitif girilir). Fark varsa onayla "Mutabakat düzeltmesi" işlemi oluşturulur; o tarihe kadarki işlemler hesap bazında işaretlenir; `reconciliations` kaydı ve denetim kaydı (`account.reconcile`) tek transaction'da.
+- `004` migration'ı: `attachments` ve `reconciliations` index'leri; işlemlerde `reconciledAccountIds` ve `isAdjustment`.
+- Testler: dosya türü tespiti, depolama, ekstre yardımcıları (birim); yükleme/dönüştürme (EXIF silme, yön, boyut, HEIC), bağlama kuralları, erişim izolasyonu, temizlik, ekstre tutarlılığı, mutabakat (entegrasyon).
+
+### Değişti — Faz 6c
+
+- Hesap adı artık hesap ekstresini açar (gizli hesaplarda bağlantı yok).
+- Bakiyeyi etkileyen alanı (tutar, tarih, tür, hesap) değiştirilen işlemin mutabakat işareti kalkar. Mutabakat düzeltmesi düzenlenemez, yalnızca silinebilir.
+- İşlemlerdeki kullanılmayan `reconciledAt` alanı, hesap bazında `reconciledAccountIds` ile değiştirildi.
+
+### Düzeltildi
+
+- `seed:reset` işlemleri ve satıcıları silmiyordu; artık işlemler, satıcılar, ekler (diskteki dosyalarıyla) ve mutabakatlar da temizlenir.
+
+### Eklendi — Faz 6b: işlemler
+
+- İşlemler (`/islemler`): gelir, gider ve transfer (hesap ↔ hesap). Tutar her zaman pozitif; işaret türden gelir. Hesap bakiyeleri artık açılış bakiyesi + gerçekleşmiş işlemlerden hesaplanır (tek doğruluk kaynağı: işlemler).
+- Bölünmüş işlem: en az 2 kalem, kalemler toplamı = tutar (istemci ve sunucuda aynı zod şeması); kalan tutar göstergesi, "kalanı son kaleme ekle"; listede tek satır, ayrıntıda kalemler.
+- Akıllı giriş: satıcı önerileri (Türkçe normalize arama, kullanım sıklığı) ve satıcının son kullanılan kategori/hesabı; işlemi kopyalama.
+- Liste: güne göre gruplama ve günlük net, gelir/gider/net özetleri, sayfalama; filtreler (tarih aralığı İstanbul gününe göre, tür, durum, hesap — transfer hedefi dahil, kategori — alt kategoriler ve bölünmüş kalemler dahil, ekleyen kişi, tutar aralığı, etiket, metin arama); filtreler URL'de.
+- İşlem ayrıntısı, düzenleme ve yumuşak silme; silme bildiriminde "Geri al".
+- CSV dışa aktarma (`/islemler/disa-aktar`): listedeki filtrelerle, bölünmüş işlem kalem başına satır; Türkçe Excel uyumlu (noktalı virgül, ondalık virgül, UTF-8 BOM), formül enjeksiyonu koruması.
+- Hızlı ekle her ekrandan doğrudan işlem formunu açar (gider/gelir/transfer sekmeleri).
+- Gizlilik: başkasının "yalnızca ben" hesabına dokunan işlemler listede, ayrıntıda ve CSV'de görünmez; o hesaba yalnızca sahibi işlem girer.
+- Seed: son 6 ayın 221 gerçekçi işlemi (faker.seed(42); maaş, kira, faturalar — kışın doğalgaz yüksek, market — bir kısmı bölünmüş, yakıt, kafe, kart ödemesi, birikim, nakit çekme), satıcı kuralları; idempotent (`seedRef`).
+- `003` migration'ı: `transactions` ve `payees` index'leri. Denetim kaydı: işlem silme/geri alma.
+- Testler: bakiye tutarlılığı (bağımsız doğrulama dahil), izolasyon, gizli hesap, arşivli kategori, filtreler, satıcı kuralları, CSV.
+
+### Değişti
+
+- `npm run typecheck` önce route tiplerini üretir (`next typegen`).
+
+### Eklendi — Faz 6a: para, hesaplar ve kategoriler
+
+- `shared/money.ts`: Türkçe tutar ayrıştırma (`"1.250,50"` → 125050 kuruş; binlik/ondalık kuralları belgeli), `formatMoneyInput`, `sumMoney`, kuruş kaybı olmadan oransal bölme (`allocate`, `splitEvenly`).
+- `shared/quantity.ts`: miktarlar birimin binde biri tamsayı (`1,5 kg` → 1500); ayrıştırma, biçimlendirme, kg↔g / lt↔ml dönüşümü.
+- `shared/dates.ts`: İstanbul günü yardımcıları (gün başlangıcı, UTC → yerel gün).
+- Hesaplar (`/hesaplar`): nakit, vadesiz banka (KMH limiti, aylık faiz, kesim günü), birikim, kredi kartı (limit, kesim günü, son ödeme kuralı, ödeme hesabı), yemek kartı (sağlayıcı); hesap sahibi kişi ve "yalnızca ben" (bakiyeyi yalnızca hesap sahibi görür, toplamlar hane ayarına uyar); renk/ikon, sıralama, arşiv. Varlık / kart borcu / net özet.
+- Kategoriler (`/kategoriler`): gelir ve gider ağaçları (5 seviyeye kadar), ekleme, düzenleme, taşıma (alt ağaçla, transaction), sıralama, arşivleme (alt ağaçla); kardeşler arasında ad tekrarı engeli (Türkçe normalize).
+- Varsayılan Türkçe kategori seti (44 kategori): yeni hanede aynı transaction'da, mevcut hanelere `002` migration'ıyla, idempotent (`defaultKey`).
+- Kategori ağacı saf fonksiyonları (`buildTree`, `toOptions`, `checkMove`, `rollupTotals` …) ve birim testleri.
+- Renk paleti (13 renk, açık/koyu tema değişkenleri) ve ikon kayıt tablosu; ikon/renk seçiciler, `MoneyInput`.
+- Seed: varsayılan kategoriler ve 7 örnek hesap (KMH'li banka, kredi kartı, birikim, "yalnızca ben" yemek kartı).
+- Denetim kaydı: hesap oluşturma/düzenleme/arşiv, kategori taşıma/arşiv.
+- Entegrasyon testleri: kategori ve hesap izolasyonu, roller, gizli bakiye, kart kuralları, ağaç kuralları.
+
+## [0.5.0] - 2026-11-05
+
+Faz 5: Haneler, hane içi roller ve veri izolasyonu.
+
+### Eklendi
+
+- Hane içi roller (`viewer < member < owner`) ve kuralları: son sahip düşürülemez veya çıkarılamaz.
+- DAL: `getHouseholdContext` (istek başına tek okuma), `requireActiveHousehold(minRole)`, `getHouseholdActionContext(minRole)`, `requireHouseholdMember(householdId, minRole)`. Sistem admini için hane verisinde ayrıcalık yok.
+- Hane servisi (`features/households/service.ts`, framework'ten bağımsız): her hane kapsamlı fonksiyon üyeliği kendisi de doğrular; hane oluşturma + ilk sahip + denetim kaydı tek MongoDB transaction'ında.
+- Aktif hane seçici (üst bar): seçim sunucuda doğrulanır, `butcem.hh` cookie'sine yazılır; geçersiz/uydurma cookie yok sayılır. Tercih yoksa en yüksek rolün olduğu hane açılır.
+- `/ayarlar`: hane adı, bütçe ayı başlangıç günü, taksit modu, günlük plan dağıtımı, "yalnızca ben" hesaplarının toplamlara dahil edilmesi, ek mağaza tasarruf eşiği; üye rolleri ve üye çıkarma (yalnızca sahip; diğer roller salt okunur).
+- `/admin/haneler`: hane oluşturma (ilk sahip seçerek), kullanıcıyı haneye ekleme, hane içi rol değiştirme, üye çıkarma.
+- `/hane-yok`: hiçbir haneye üye olmayan kullanıcılar için yönlendirme sayfası.
+- Denetim kaydı (`auditLogs`): hane ayarları, üye ekleme/rol/çıkarma, hane oluşturma ve tüm admin kullanıcı işlemleri (oluşturma, düzenleme, rol, şifre sıfırlama, askı, silme).
+- Migration mekanizması: `npm run migrate`, `scripts/migrations/NNN-*.ts`, uygulananlar `migrations` koleksiyonunda; `001-initial-indexes`. Seed önce migration'ları çalıştırır.
+- Veri izolasyonu entegrasyon testleri (başka hanenin üyeliği/ayrıntısı/ayarları, rol yetersizliği, uydurma ve enjeksiyon denemesi kimlikler, hanesi olmayan admin, çapraz hane üyelik değişikliği, son sahip, transaction).
+
+### Değişti
+
+- İzleyici (viewer) rolünde Hızlı ekle gizlenir/pasifleşir.
+- Kullanıcı silindiğinde tüm hane üyelikleri de temizlenir.
+
+### Kaldırıldı
+
+- Hane mock verisi.

+- Hane içi roller: **sahip** (ayarlar, üyeler), **üye** (veri girer), **izleyici** (yalnızca görüntüler).
+- Her sayfa, Server Action ve API, hane yetkisini `src/lib/dal.ts` üzerinden sunucuda doğrular; servisler de üyeliği ayrıca kontrol eder.
