+
+Faz 13: alışveriş listeleri, akıllı mağaza önerisi, alışveriş modu ve alışveriş sonrası giriş (13a ve 13b alt fazları).
+
+### Eklendi — Faz 13b: alışveriş sonrası giriş, karşılaştırma ve "Alışverişi tamamla"
+
+- Alışveriş sonrası giriş (`/alisveris/:id/tamamla`): liste kalemleri tek tek işaretlenir; her biri için alınan ürün (aynı ya da aynı ürün tipinden muadil; ürün tipi kaleminde marka belirtmeden de), mağaza, paket adedi ve ödenen tutar. Tutar, bilinen paket fiyatıyla ön doldurulur. Listede olmayan ekstra ürünler eklenebilir. Mağaza başına ödeme hesabı (yemek kartı geçen mağazada uygun yemek kartı önseçili) ve fiş görselleri.
+- "Alışverişi tamamla" tek MongoDB transaction'ı: stok alım hareketleri, fiyat kayıtları (kaynak `receipt`; ürün × mağaza başına, paket fiyatı = tutar / paket), mağaza başına bölünmüş gider işlemi (kalemler stok kategorisinin eşlendiği gider kategorisine; eşlenmemiş ve serbest metin kalemleri seçilen yedek kategoriye), fiş görselleri işlemin eki, alınmayanların taşınması ve listenin kapanması. Herhangi bir adım başarısızsa hiçbir şey yazılmaz.
+- Alınmayanlar: başka aktif listeye taşı, yeni liste aç ya da bırak.
+- Karşılaştırma raporu (tamamlanan listede): planlanan (tamamlama anındaki akıllı öneri) vs. gerçekleşen tutar ve fark; farkın nedenleri (aynı üründe fiyat farkı, miktar farkı, muadil, alınmayanlar, plansız ekstralar, planda fiyatı olmayanlar; toplamları farka eşit); kalem bazında Aynı / Muadil / Alınmadı / Plansız ekstra; mağaza giderleri ve kullanılan hesaplar. Etiketler tamamlama anındaki hâliyle saklanır.
+- Liste sayfasında ve alışveriş modunda "Alışverişi tamamla" düğmesi.
+- Stok hareketleri ve işlemlerde `shoppingListId` (kaynağı izlemek için).
+- Testler: eşleşme ve fark ayrıştırması (birim); tamamlama ekranı verisi, doğrulamalar (muadil tipi, gelecek tarih, izleyici), ek dosya hatasında geri alma, stok/fiyat/mağaza başına bölünmüş gider, markasız kalem, kalanların taşınması ve rapor (entegrasyon).
+
+### Eklendi — Faz 13a: alışveriş listeleri, stok önerileri, akıllı mağaza önerisi, alışveriş modu
+
+- Alışveriş listeleri (`shoppingLists`, `/alisveris`): birden çok aktif liste; kalem olarak ürün tipi (genel), belirli ürün (marka/paket) ya da serbest metin. Miktar ürün tipinde tipin biriminde, üründe paket adedi; boşsa en az bir paket. Aynı ürün listede iki kez olamaz; kalem düzenleme, çıkarma ve başka aktif listeye taşıma. Liste silme soft delete ve denetim kaydı. Aile üyeleri aynı listeyi kullanır: sayfa odaklanınca ve 30 saniyede bir yenilenir.
+- Stok eşiği önerileri: eşiğin altındaki ürün tipleri hiçbir aktif listede yoksa liste sayfasında onayla/reddet önerisi olarak gelir (fire ayarlı önerilen miktar ve nedeni). Onaylanan önerilen miktarla eklenir ("Stok önerisi" rozeti), "Tümünü ekle" ile toplu. Reddedilen öneri, ürün için yeni alım girilene (stok yenilenene) kadar gösterilmez.
+- Akıllı mağaza önerisi (saf fonksiyon, birim testli): son bilinen fiyatlarla her kalem için mağaza ve marka; ihtiyacı karşılayan paket sayısı × paket fiyatı. Fiziksel mağaza ziyareti ve hacimli kalemler için zahmet skoruna bağlı maliyet cezası, online teslimat ücreti ve ücretsiz teslimat alt limiti, yemek kartı önceliği (kartın geçtiği mağazada kartla ödenebilecek tutar avantajlı sayılır; bakiye mağazalar arasında bir kez harcanır). En az mağazalı eksiksiz plandan başlanır; ek mağaza ancak tasarruf hane ayarındaki eşiği aşarsa eklenir. Çıktı: "Tek mağaza en iyi seçenek: X" ya da "Önerilen dağılım: A (7 ürün), B (3 ürün): Y (Z tasarruf)"; önerilen ve tek mağaza dağılımları, fiyatı bilinmeyen kalemler.
+- Alışveriş modu (`/alisveris/:id/mod`): plana göre mağazaya gruplanmış, büyük dokunma alanlı kontrol listesi; "sepete alındı" işareti anında görünür ve kaydedilir, ilerleme çubuğu; önerilen / tek mağaza planı arasında geçiş.
+- Ürün tipine "Ağır / hacimli" işareti (akıllı öneride taşıma cezası).
+- Dashboard'da "Alışveriş" kartı (aktif listeler ve bekleyen öneri sayısı); stok sayfasındaki "Alınması önerilenler" alışveriş listelerine bağlanır. Kenar menüde "Alışveriş".
+- Migration `015-shopping-lists`. Seed: "Haftalık market" (9 kalem: tip, marka, serbest metin, fiyatı olmayan domates) ve "Ay sonu toptan" listeleri; deterjan, yumuşatıcı, çamaşır suyu ve tuvalet kağıdı hacimli.
+- Testler: planlayıcı (paket yuvarlama, marka kısıtı, eşik, eksik kapsama, zahmet ve hacimli cezası, teslimat, yemek kartı), miktar ve öneri reddi kuralları (birim); liste/kalem işlemleri, yetki, öneri onay/red, plan çıktısı, silme ve denetim (entegrasyon).
+
+### Değişti — Faz 13a
+
+- Fiyat servisinde ürün tipi teklifleri ortak yükleyicide (`loadTypeOffers`); tüketim analizindeki son birim fiyat da bunu kullanır.
+
+## [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).

 - **Faz 9 kararları (2026-11-05):** 9a varlık lotları ve kâr/zarar, 9b dönemsel rapor ve net varlık; `v0.9.0` 9b sonunda. 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.
 - **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.
+- **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.
+- **Faz 13 kararları (2026-11-06):** 13a alışveriş listeleri, stok eşiği önerileri (onayla/reddet), akıllı mağaza önerisi ve alışveriş modu; 13b alışveriş sonrası giriş, karşılaştırma raporu ve "Alışverişi tamamla"; `v0.13.0` 13b sonunda. Birden çok mağazadan alışverişte mağaza başına ayrı bölünmüş gider (her mağaza için ayrı hesap ve fiş). Tamamlanınca liste kapanır ve rapor sabitlenir; alınmayanlar başka aktif listeye taşınır, yeni listeye alınır ya da bırakılır. Reddedilen öneri yeni alım girilene kadar gösterilmez. Markası belirtilmeyen ürün tipi kalemi (ör. pazardan domates) tipin biriminde stoğa işlenir, fiyat kaydı oluşmaz.
 - **Lokal MongoDB portu:** host'ta `27019` (27017 ve 27018 geliştirme makinesinde dolu). `BUTCEM_MONGO_PORT` ile değiştirilebilir.
