+Faz 11: ev stoğu (11a ve 11b alt fazları).
+
+### Eklendi — Faz 11b: periyodik sayım, fire ayarlı öneri, tüketim analizi
+
+- Sayım oturumları (`stockCounts`): her sayımda ürün başına beklenen, sayılan ve fireye ayrılan miktar; fark sıfır olsa da kayıt tutulur ve oluşan hareketler oturuma bağlanır (`countId`). Ürün detayındaki tek ürün sayımı da oturum oluşturur.
+- Periyodik sayım ekranı (`/stok/sayim?kategori=…`): kategori (alt ağacıyla) veya tüm stok; liste hâlinde beklenen → sayılan, anlık fark; eksiğin bir kısmı nedenle fire olarak işaretlenebilir (fire, eksikten fazla olamaz), kalan fark sayım düzeltmesi olur. "Yalnızca sayımı gelenler", "Beklenenle doldur", tek transaction'da kayıt.
+- Sayım takvimi: sıklık ürün tipinden, yoksa stok kategorisinden (üstten devralınır); son sayımdan (hiç sayılmadıysa ilk hareketten) n gün sonra sayım gelir. `/stok`'ta "Sayımı gelenler" kartı (kategori, ürün sayısı, gecikme) ve dashboard hatırlatması.
+- Önerilen alım miktarı motoru: hedef − mevcut; son 3 alımda fire varsa (fireler FIFO ile hangi alımdan düştüyse ona yazılır, ≥ %5) fire oranı kadar düşürülür; haftalık tüketim adımdan büyükse haftalık tüketimin katına, değilse adıma yuvarlanır; hedefi aşmaz. Gerekçe gösterilir ("Son 2 alımda %30 fire, miktar azaltıldı.", "Haftalık tüketime (0,3 kg) göre yuvarlandı.", "Mevcutla birlikte yaklaşık 46 gün yeter.").
+- Tüketim hızı (son 90 gün; tüketim + sayımda çıkan eksik, fire hariç) ve periyodik sayım durumu ürün detayında.
+- Tüketim analizi (`/stok/analiz`): ürün tipi başına son 6 ayın tüketim/fire çubukları, aylık ortalama tüketim ve fire, fire oranı (≥ %15 vurgulu), bu ayın tüketimi. Maliyet ürün fiyatlarıyla (Faz 12) eklenecek.
+- Migration `012-stock-counts`: index'ler; Faz 11a'da oturumsuz kaydedilen sayım düzeltmeleri, beklenen miktar yeniden hesaplanarak sayım oturumlarına bağlanır.
+- Seed: Çakır Ailesi'nde Mutfak 15, Genel Temizlik 30 günde bir sayılır; sayım oturumları ve ara sıra sayım farkı; Mutfak'ın sayımı gecikmiş.
+- Testler: FIFO fire dağılımı, son alımların fire oranı, öneri (fire indirimi, tüketim hızına yuvarlama, hedef sınırı), sayım takvimi, aylık kullanım (birim); seed sayım takvimi, toplu sayım (fire + düzeltme, oturum, sıfır fark, yetki), tüketim analizi (entegrasyon).
+
+### Değişti — Faz 11b
+
+- Dashboard stok kartı "Stok uyarıları" oldu: azalan ürünler, SKT yaklaşan partiler ve sayımı gelen kategoriler.
+- Seed'deki sayım farkları artık periyodik sayım oturumlarında oluşur.
+
+### Eklendi — Faz 11a: ev stoğu
+
+- Stok kategorileri (`stockCategories`): gider kategorilerinden ayrı, sınırsız derinlikte ağaç; varsayılan set (Mutfak › Manav, Şarküteri, Bakliyat; Genel Temizlik › Bulaşık, Çamaşır, Genel; Kişisel Temizlik › Şampuan, Tıraş, Kişisel Bakım) yeni hanede ve migration ile mevcut hanelere yüklenir. Her kategori bir gider kategorisine eşlenebilir (alt kategoriler üstten devralır; Faz 13'te alışveriş gideri için) ve sayım sıklığı tutar. Taşıma, arşiv (içinde aktif ürün yoksa) ve arşivden çıkarma; `/stok/kategoriler`.
+- Ürün tipleri (`productTypes`): kategori, temel ölçü birimi (kg, lt, adet … veya özel birim: "yıkama", "tablet"), hedef stok, kritik eşik yüzdesi (varsayılan %20), saklama yeri, "1 azalt" miktarı, not; ilk kurulumda evdeki başlangıç miktarı.
+- Stok hareketleri (`stockMovements`): alım (isteğe bağlı SKT), tüketim, fire/zarar (nedenli) ve sayım düzeltmesi (gerçek miktar girilir, fark işlenir). Mevcut miktar hareketlerden türetilir; stokta olandan fazla tüketim/fire reddedilir. Hareket silme denetim kaydına yazılır.
+- SKT takibi FIFO partileriyle: çıkışlar en eski girişten düşer; evde kalan miktarın SKT'si 7 gün içinde dolan veya geçmiş partiler uyarılır.
+- `/stok`: özet, "Alınması önerilenler" (eşiğin altındakiler ve hedefe tamamlayan miktar), SKT uyarıları, kategoriye göre ürün listesi (mevcut/hedef çubuğu ve eşik çizgisi, arama, "yalnızca azalanlar"), tek dokunuşla "1 azalt". `/stok/:id`: partiler ve hareket geçmişi.
+- Dashboard "Azalan stoklar" kartı.
+- Seed: Çakır Ailesi için 19 ürün tipi ve son 6 ayın haftalık alım/tüketim/fire/sayım simülasyonu.
+- Testler: mevcut miktar, FIFO partileri, SKT durumu, eşik ve öneri (birim); görünüm, izolasyon, hareket kuralları, sayım, kategori kuralları (entegrasyon).
+
+## [0.10.0] - 2026-11-06
+
+Faz 10: aylık bütçe, gelir planı ve günlük plan (10a ve 10b alt fazları).
+
+### Eklendi — Faz 10b: gelir planı ve günlük plan
+
+- Gelir planı (`/butce` altında): gerçekleşen gelirler, henüz gerçekleşmemiş planlı (düzenli) gelirler ve elle eklenen beklenen gelirler (`budgets.incomeItems`, ör. prim); beklenen toplam. "Plana göre elde kalacak" (beklenen gelir − bütçe) ve "Bu tempoda elde kalacak" (beklenen gelir − ay sonu tahmini gider).
+- Günlük plan (dashboard): ayın bütçesi günlere yayılır; tarihe bağlı giderler (düzenli işlemler, taksitler) kendi günlerine, kalan değişken bütçe günlere eşit veya hane ayarına göre önceki ayın günlük örüntüsüyle (kuruşu kuruşuna toplam korunur). "Bugün ayın %X'i geçti, bütçenin %Y'si harcandı", bugün için harcanabilir tutar (önceki günlerden kalan/aşan dahil), bugüne kadar planlanan ve harcanan, ay sonunda elde kalacak.
+- Kümülatif planlanan / gerçekleşen gider grafiği, beklenen gelir referans çizgisi ve gün tablosu; sonraki ayın beklenen geliri ile bütçesi karşılaştırması.
+- Dashboard özet kartları: "Bu ay gelir", "Bu ay gider" ve "Kalan" gerçek veriyle (bütçe ayına göre).
+- Testler: dağıtım ve kuruş yuvarlama, örüntü uyarlama, günlük plan ve bugünkü pay, taban hızlı tahmin (birim); gelir planı, gizli hesap ayarı, elle kalemler, yetki, günlük plan tutarlılığı ve örüntü modu (entegrasyon).
+
+### Değişti — Faz 10b
+
+- Ay sonu tahmini: değişken giderin günlük hızı, bu ayın hızı ile önceki dönemin değişken harcama hızının karışımı (ay ilerledikçe bu ayın ağırlığı artar); ay başındaki tek bir büyük harcama artık tüm aya yayılmıyor. Geçmişi olmayan hanede yalnızca bu ayın hızı.
+
+### Düzeltildi — Faz 10b
+
+- Bütçede "sabit gider" (düzenli işlem / taksit) ayrımı her işlemi sabit sayıyordu (`installment` boşken alan yolu eksik değer verir ve `null`'a eşit sayılmaz); ay sonu tahmini değişken gideri hiç yansıtmıyordu. `$ifNull` ile düzeltildi, regresyon testi eklendi.
+
+### Eklendi — Faz 10a: aylık bütçe
+
+- Bütçe sayfası (`/butce?ay=YYYY-MM`): ay gezintisi, dönem sınırları hane ayarı `budgetMonthStartDay`'e göre (ör. 15'i → 15 Kasım – 14 Aralık).
+- Kategori limitleri (`budgets`): her gider kategorisine limit; üst kategori limiti alt kategorileri kapsar, alt kategori limiti üstün içinde alt sınırdır ve toplam bütçede iki kez sayılmaz. Limitsiz alt kategoriler "Üst kategori limitinde" olarak gösterilir; hiçbir limitin kapsamadığı harcama "Bütçesiz harcama" toplamında.
+- Gerçekleşen / limit / kalan, yüzde çubuğu (ayın geçen kısmı işaretli), %80'de uyarı, %100'de "Limit doldu", aşımda "Limit aşıldı".
+- Ay sonu tahmini: sabit giderler (düzenli işlem, taksit) olduğu gibi + kalan planlı giderler + değişken giderin günlük hızıyla ay sonuna yansıtılması; tahmin limiti aşıyorsa işaret.
+- Bölünmüş işlemler kalem bazında; taksitler hane ayarına göre her biri kendi ayına (varsayılan) veya tamamı alış ayına. Başkasının "yalnızca ben" hesabından giderler hane ayarına göre yalnızca tutar olarak sayılır.
+- "Önceki aydan kopyala" ve "Önceki ayın harcamalarından oluştur" (ana kategori bazında, 100 TL'ye yukarı yuvarlanır); mevcut limitler varsa onay istenir.
+- Limit düzenleyici: tüm etkin gider kategorileri ağaç sırasıyla, anlık toplam bütçe.
+- Dashboard: %80'i geçilen veya aşılan kategori sayısıyla uygulama içi bütçe uyarısı.
+- Seed: Çakır Ailesi'nde önceki ve bu ay için harcamalardan oluşturulmuş bütçeler (bu ay Market limiti düşük, Elektrik alt limiti).
+- `010` migration'ı: `budgets` index'i (hane × ay benzersiz).
+- Testler: dönem sınırları, eşikler, tahmin, üst/alt limit toplama, bütçesiz harcama, sıra (birim); limitler, bölünmüş işlem, planlı, gizli hesap ayarı, taksit modları, başlangıç günü, kopyala/oluştur, yetki (entegrasyon).

Limit her gider kategorisine verilebilir; üst kategori limiti alt kategorileri kapsar, alt kategori limiti üstün içinde alt sınırdır (toplamda iki kez sayılmaz). Başkasının "yalnızca ben" hesabından yapılan harcama hane ayarına (gizli hesapları toplamlara kat) göre yalnızca tutar olarak bütçeye girer.
+- **Faz 11 kararları (2026-11-06):** 11a stok kategorileri, ürün tipleri, hareketler, SKT ve %20 eşik; 11b periyodik sayım, fire ayarlı öneri ve tüketim analizi; `v0.11.0` 11b sonunda. Eşiğin altındaki ürünler Faz 11'de "Alınması önerilenler" listesinde gösterilir (koleksiyon yok); Faz 13'te aktif alışveriş listesine onayla/reddet önerisi olarak bağlanır. SKT alım hareketinde (isteğe bağlı) girilir; tüketim ve fire FIFO ile en eski alımdan düşülür.
 - **Lokal MongoDB portu:** host'ta `27019` (27017 ve 27018 geliştirme makinesinde dolu). `BUTCEM_MONGO_PORT` ile değiştirilebilir.
