+## [0.12.0] - 2026-11-06
+
+Faz 12: mağazalar, ürünler, fiyatlar ve birim fiyat (12a ve 12b alt fazları).
+
+### Eklendi — Faz 12b: fiyat kayıtları ve birim fiyat
+
+- Fiyat kayıtları (`productPrices`): ürün × mağaza × tarih × paket fiyatı; kampanya/indirim işareti ve geçerlilik sonu; kaynak `manual` | `receipt` | `provider:<ad>` (şimdilik elle giriş). Gelecek tarihli fiyat ve arşivli ürün/mağazaya fiyat girilemez; kayıt silme denetim kaydına yazılır.
+- Birim fiyat: her fiyat ürün tipinin birimine çevrilir (TL/kg, TL/lt, TL/adet, TL/yıkama; g ve ml gösterimde kg ve lt). Yuvarlama yalnızca gösterimde. Geçerli fiyat mağaza başına son kayıt; süresi biten kampanyada önceki normal fiyata dönülür ("Kampanya bitti, normal fiyat"), 90 günden eski fiyat işaretlenir.
+- Ürün tipi detayında "Birim fiyat karşılaştırması": tüm marka/paket ve mağazalar birim fiyata göre sıralı, en uygun vurgulu, diğerleri "%X pahalı"; buradan fiyat girişi (birim fiyat anlık önizlemesiyle).
+- Ürün sayfası (`/stok/urunler/:id`): görseller, mağazalardaki geçerli fiyatlar, mağaza başına fiyat geçmişi grafiği (basamaklı çizgi, bugüne uzanır) ve fiyat kayıtları listesi. Mağaza renkleri sabit kategorik paletten (mağazanın ekleniş sırası; açık/koyu tema için doğrulanmış `--series-1…8`).
+- Tüketim analizinde aylık ortalama maliyet: aylık ortalama tüketim × ürün tipinin son bilinen birim fiyatı; fiyatı bilinen ürünlerin toplamı.
+- Migration `014-product-prices`. Seed: 22 ürün için son 6 ayın 265 fiyat kaydı (mağaza farkları, aylık artış, süren ve biten kampanya, eski fiyat örneği).
+- Testler: birim fiyat ve gösterim birimi, geçerli fiyat (biten kampanya, eski fiyat), sıralama ve eşitlik, renk yuvası (birim); karşılaştırma sırası, kampanya dönüşü, fiyat girişi kuralları, silme ve denetim, analiz maliyeti (entegrasyon).
+
+### Değişti — Faz 12b
+
+- Sayfa başlığı açıklaması bağlantı içerebilir; ek dosya seçicisine özel düğme metni ve ipucu.
+
+### Eklendi — Faz 12a: mağazalar ve ürünler (marka/paket)
+
+- Mağazalar (`stores`, `/magazalar`): ad, tür (fiziksel market / online platform / pazar), şube, eve uzaklık (km), taşıma güçlüğü (1–5), online ise teslimat ücreti ve ücretsiz teslimat alt limiti, yemek kartı geçerliliği ve geçerli sağlayıcılar, not. Zahmet skoru (0–100; uzaklık 20 km'ye kadar ve taşıma güçlüğü eşit ağırlıkla, online mağazada uzaklık sayılmaz) ve düzeyi; "ada göre / en yakın / en uzak / en zahmetli" sıralama. Aynı ad + şube tekil; arşivleme denetim kaydına yazılır. Kenar menüde "Mağazalar".
+- Ürünler (`products`): ürün tipine bağlı marka, tanım, isteğe bağlı barkod (8–14 rakam, hanede tekil), paket miktarı ve birimi. Paket birimi ürün tipinin birimine kendiliğinden çevrilebiliyorsa (aynı birim, kg↔g, lt↔ml) dönüşüm otomatik; çevrilemiyorsa dönüşüm zorunlu ("5 kg = 33 yıkama", "1 paket = 50 tablet", "75 ml = 1 adet"). Ürün tipinin birimi sonradan değişirse "Dönüşüm gerekli" uyarısı.
+- Ürün görselleri: birden çok görsel, mevcut ek dosya altyapısıyla (WebP'ye dönüştürme, küçük resim, yetkili okuma; hane üyeleri görür). Liste küçük resmi ve görüntüleyici.
+- Ürün tipi detayında "Ürünler (marka / paket)" bölümü; `/stok/urunler` ürün kataloğu (ürün tipine göre gruplu, marka/tanım/barkodla arama, arşiv).
+- Migration `013-stores-products` (index'ler). Seed: Çakır Ailesi için 8 mağaza ve 22 ürün.
+- Testler: zahmet skoru, sıralama, uzaklık gösterimi, paket dönüşümü ve açıklaması (birim); mağaza şeması ve kuralları, ürün dönüşüm zorunluluğu, barkod tekilliği, görsel bağlama/sıralama/çıkarma ve okuma yetkisi, arşiv (entegrasyon).
+
+## [0.11.0] - 2026-11-06
+
+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).

Varlıklar hane ortaktır; "yalnızca ben" işaretli varlık ve hareketleri yalnızca sahibine görünür. Varlık alım/satışı hesaba bağlıysa transfer olarak kaydedilir (gelir/gider raporlarına girmez). Aynî kayıt "aynı varlıkla" kapanırken isteğe bağlı olarak varlıktan düşülür / varlığa eklenir.
 - **Faz 10 kararları (2026-11-06):** 10a aylık bütçe, 10b gelir planı ve günlük plan; `v0.10.0` 10b sonunda. 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.

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.
+- **Faz 12 kararları (2026-11-06):** 12a mağazalar ve ürünler (marka/paket, görseller), 12b fiyat kayıtları, birim fiyat ve fiyat geçmişi; `v0.12.0` 12b sonunda. Mağazalar, ürünler ve fiyatlar hane bazlıdır (hane içinde ortak, başka hane görmez). Paket birimi ürün tipinin birimine kendiliğinden çevrilemiyorsa ürün kaydında dönüşüm zorunludur ("5 kg = 33 yıkama"); her fiyat ürün tipinin biriminde karşılaştırılır.
