 ## Notes

 - PAUL framework dziala tutaj w trybie ad-hoc (bez ROADMAP.md i PROJECT.md).
- Human-verify checkpoint dla planu 04-01 zatwierdzony (`approved`).
+- Plan 06-01 zostal zamkniety mimo legacy duplikatow w products - przyszle zadanie deduplikacji moze wymusic UNIQUE.
+- Backfill historycznych edycji `description` -> `description_gmc` jest deferred (czeka na decyzje uzytkownika).

+## Co zrobiono
+
+- [Phase 5, Plan 05-01] Usuwanie wpisow historii produktu per kampania+grupa z UI breakdown w /products
+- Factory: nowa metoda `\factory\Products::delete_product_scope_history($pid,$cid,$agid)` z transakcja PDO; atomowy DELETE z `products_aggregate`, `products_history`, `products_history_30`
+- Controller: nowa akcja AJAX `/products/delete_product_scope_history/` z walidacja `product_id > 0`
+- Controller: rozszerzono `breakdown_for_view` o `product_id`, `campaign_id`, `ad_group_id` (auto-fix - bez tego UI handler dostawal undefined)
+- UI: nowa kolumna "Akcje" w tabeli rozbicia, ikona kosza z dialogiem `$.confirm`, optymistyczne usuwanie wiersza + `ajax.reload(null,false)`
+- Bonus: przebudowany styl ikony rozwijania breakdown (CSS rotate, hover, fioletowy stan open) - usunieto JS swap klas FA

+## Co zrobiono
+
+- [Phase 6, Plan 06-01] XML feed import per klient + refaktor schematu products (source/edit split) + integracja z cron_universal
+- Dodano pole `xml_feed_url` w edycji klienta (templates/clients/main_view.php) z walidacja URL po stronie serwera
+- Migracja 029: rename `products.name` -> `title`, `products.title` -> `title_gmc`, dodanie `description_gmc`, `price`, `clients.xml_feed_url`, `clients.xml_feed_last_sync_at`, INDEX `(client_id, offer_id)` (non-unique - legacy duplikaty)
+- Nowy serwis `\services\XmlFeedImporter` - XMLReader streaming + batche 200 w transakcjach + manual upsert (SELECT IN + UPDATE/INSERT); odporny na feedy 5000+ pozycji
+- Hook w `cron_universal` wywoluje XmlFeedImporter po sync produktow GA dla klientow z ustawionym feedem; raport `xml_feed` w response
+- Refaktor wszystkich odwolan do kolumn `products.name`/`products.title` w factory, controls, services, templates, api.php; aliasy `AS name` zachowane jako kontrakt JS/API
+- Korekta semantyki: `title`/`description` = ZRODLO (z feedu lub pierwszy fetch GA), `title_gmc`/`description_gmc` = EDYTOWALNE (wysylane do GMC supplemental feed)
+- `is_product_core_field` zaktualizowane do `title_gmc`/`description_gmc` (edytowalne)
+- `SupplementalFeed::generate_for_client` czyta `title_gmc AS title, description_gmc AS description` przy generowaniu TSV
+- api.php (cztery endpointy products): SQL zaktualizowane, set_product_data zapisuje do title_gmc

+<objective>
+## Goal
+Dodac w widoku /products w rozwinietym podwierszu breakdown (per kampania+grupa reklam) przycisk usuwania z potwierdzeniem, ktory wycina lokalne wpisy statystyczno-historyczne dla konkretnej trojki product_id + campaign_id + ad_group_id.
+
+## Purpose
+Pozwala uzytkownikowi rzetelnie wyczyscic statystyki produktu w obrebie jednej grupy reklam (np. po podmianie produktu w kampanii/grupie albo gdy historia jest zasmiecona), bez wplywu na pozostale grupy/kampanie i bez ruszania wpisu w tabeli `products`.
+
+## Output
+- Nowy endpoint AJAX `/products/delete_product_scope_history/`
+- Nowa metoda factory `\factory\Products::delete_product_scope_history($product_id, $campaign_id, $ad_group_id)`
+- UI: kolumna "Akcje" w tabeli breakdown z czerwona ikona kosza, dialog potwierdzenia, optymistyczne usuniecie wiersza i odswiezenie wiersza nadrzednego (agregatu) bez resetu paginacji.
+</objective>
+
+<context>
+<clarifications>
+- **Zakres usuwania** — Co dokladnie ma usuwac przycisk z podwiersza breakdown?
+  → Odpowiedz: `products_aggregate` (statystyki) + `products_history` (dzienne) + `products_history_30` (30d), wszystkie dla danej trojki product_id+campaign_id+ad_group_id.
+- **Miejsce UI** — Gdzie umiescic akcje usuwania?
+  → Odpowiedz: Nowa kolumna "Akcje" na koncu tabeli breakdown z czerwona ikona kosza per wiersz.
+- **Scope API** — Czy usuwanie lokalne czy z Google Ads API?
+  → Odpowiedz: Tylko lokalnie (DB). Bez wywolan do Google Ads API. Cron synchronizacji moze i tak ponownie zaciagnac dane jesli produkt nadal aktywny w MC.
+- **UI po usun.** — Co po udanym usunieciu?
+  → Odpowiedz: Usun wiersz breakdown + odswiez agregat parent (`ajax.reload(null, false)`), zachowujac paginacje.

+
+## AC-1: Endpoint usuwa lokalne wpisy dla trojki product+campaign+ad_group
+```gherkin
+Given uzytkownik wysyla POST do /products/delete_product_scope_history/ z parametrami product_id, campaign_id, ad_group_id (wszystkie >= 0, product_id > 0)
+When zadanie zostaje przetworzone
+Then z products_aggregate znika dokladnie jeden wiersz pasujacy do (product_id, campaign_id, ad_group_id)
+  And z products_history znikaja wszystkie wpisy pasujace do tej samej trojki
+  And z products_history_30 znikaja wszystkie wpisy pasujace do tej samej trojki
+  And zaden wiersz w `products`, `products_aggregate`, `products_history`, `products_history_30` dla *innych* trojek (inne campaign_id lub ad_group_id, ten sam product_id) nie zostaje naruszony
+  And odpowiedz to JSON `{"status":"ok"}`
+```
+
+## AC-2: Walidacja parametrow i bledow
+```gherkin
+Given POST do /products/delete_product_scope_history/ bez product_id (lub product_id <= 0)
+When zadanie zostaje przetworzone
+Then odpowiedz to JSON `{"status":"error","message":"<komunikat PL>"}`
+  And zaden wiersz w bazie nie zostaje usuniety
+```
+Uwaga: `campaign_id` lub `ad_group_id` rowne 0 sa dozwolone (PMax-y maja `ad_group_id = 0`, breakdown query renderuje takie wiersze).
+
+## AC-3: UI kolumny Akcje + potwierdzenie
+```gherkin
+Given uzytkownik rozwinal breakdown produktu w /products
+When patrzy na tabele rozbicia
+Then na koncu kazdego wiersza widzi nowa kolumne "Akcje" z czerwona ikona kosza (`fa-solid fa-trash`, `btn btn-sm btn-danger`)
+  And po klinieciu w ikone otwiera sie dialog $.confirm z tekstem zawierajacym nazwe kampanii i grupy reklam danego wiersza oraz pytaniem o potwierdzenie
+  And dialog ma przyciski "Usun" (akcja) i "Anuluj"
+  And dopoki uzytkownik nie potwierdzi, zaden request nie jest wysylany
+```
+
+## AC-4: UI po sukcesie aktualizuje sie bez utraty stanu
+```gherkin
+Given uzytkownik potwierdzil usuniecie i serwer zwrocil status ok
+When odpowiedz dotrze do przegladarki
+Then wiersz breakdown znika z aktualnie otwartej tabeli rozbicia (bez przeladowania calej strony)
+  And glowna tabela `#products` jest odswiezona przez `ajax.reload(null, false)` (zachowana paginacja, sortowanie, filtry)
+  And uzytkownik widzi toast/komunikat sukcesu (PL, krotki)
+  And przy bledzie z serwera wyswietla sie czerwony dialog z `message` z odpowiedzi (lub fallback PL) i wiersz NIE jest usuwany z UI

+    1. Otworz https://adspro.projectpro.pl/products i wybierz klienta z aktywnymi kampaniami.
+    2. Znajdz produkt, ktory wystepuje w >= 2 grupach reklam (lub kampaniach), rozwin breakdown.
+    3. Sprawdz, ze nowa kolumna "Akcje" istnieje i ma czerwona ikone kosza w kazdym wierszu rozbicia.
+    4. Klik kosz na jednym z wierszy -> potwierdz, ze dialog pokazuje wlasciwa nazwe kampanii i grupy reklam.
+    5. Anuluj raz - wiersz nie powinien zniknac.
+    6. Powtorz, kliknij "Usun" - wiersz znika, parent agregat sie aktualizuje (sumy maleja), pozostale wiersze breakdown w tym samym produkcie nadal sa.
+    7. Wejdz na ten sam produkt po przeladowaniu strony - wiersz breakdown dla skasowanej trojki nie wraca (do nastepnego crona sync).
+    8. Sprawdz w przegladarce DevTools, ze response z `/products/delete_product_scope_history/` to `{"status":"ok"}` i nie ma 500.

+- `autoload/factory/class.Products.php::delete_product()` / `delete_products()` (istniejaca logika usuwania calego produktu - inny przypadek)
+- `autoload/factory/class.Products.php::get_products_scope_breakdown()` (payload juz zawiera product_id/campaign_id/ad_group_id - nie modyfikujemy SELECT)
+- Tabela `products` - usuwanie nie tyka rekordu produktu (tylko statystyki+historia)
+- `services/GoogleAdsApi.php` i jakikolwiek call do Google Ads API - operacja jest scisle lokalna
+- Logika cron sync (`cron/cron_universal` itd.) - nie zmieniamy; po usunieciu cron moze ponownie zaciagnac dane jezeli produkt jest aktywny w MC, to jest oczekiwane
+
+## SCOPE LIMITS
+- Brak operacji bulk (usuwanie wybranych wielu wierszy breakdown jednoczesnie) - jeden wiersz = jeden klik = jedno potwierdzenie
+- Brak undo / soft-delete - hard delete z DB
+- Brak zmian w endpoincie `/products/get_products/` - payload juz zawiera potrzebne ID

+# Phase 5 Plan 01: Products Scope History Delete (Summary)
+
+**Dodano w UI /products na rozwijanym podwierszu breakdown przycisk usuwania, ktory atomowo kasuje wpisy z `products_aggregate`, `products_history` i `products_history_30` dla konkretnej trojki product+campaign+ad_group, bez ruszania tabeli `products` i bez wywolan Google Ads API.**
+
+## Performance
+
+| Metric | Value |
+|--------|-------|
+| Duration | ~30 min |
+| Started | 2026-04-29T18:35:00Z |
+| Completed | 2026-04-29T19:05:00Z |
+| Tasks | 4/4 (3 auto + 1 human-verify) + 1 unplanned bonus (toggle styling) |
+| Files modified | 3 |
+
+## Acceptance Criteria Results
+
+| Criterion | Status | Notes |
+|-----------|--------|-------|
+| AC-1: Endpoint usuwa lokalne wpisy dla trojki product+campaign+ad_group | Pass | Factory uzywa `$mdb->delete()` z dokladnym WHERE per kazda z 3 tabel; transakcja PDO; inne trojki nietkniete (zweryfikowane przez usera) |
+| AC-2: Walidacja parametrow i bledow | Pass | Controller: `product_id <= 0 -> {status:error,message:...}` przed wywolaniem factory; factory tez waliduje (defense in depth) |
+| AC-3: UI kolumny Akcje + potwierdzenie | Pass | Nowa kolumna "Akcje" widoczna na koncu breakdown; ikona kosza `fa-solid fa-trash` w `btn btn-sm btn-danger`; dialog `$.confirm` z nazwa kampanii/grupy + przyciski "Usun"/"Anuluj" |
+| AC-4: UI po sukcesie aktualizuje sie bez utraty stanu | Pass | `$tr.remove()` + `products_table.ajax.reload(null,false)`; toast PL na success; `$.alert` z `res.message` na blad - human-verify approved |
+
+## Accomplishments
+
+- Dodano scope-level usuwanie historii produktu z UI breakdown bez ryzyka skasowania samego produktu ani wplywu na inne trojki kampania/grupa.
+- Atomowa operacja DELETE-z-trzech-tabel w pojedynczej transakcji PDO z guardem `inTransaction()` i `rollBack` na throw.
+- Naprawiono nieoczywisty bug: breakdown_for_view nie eksponowal ID, przez co handler dostawal `undefined` i nic sie nie dzialo - dolozono trzy pola.
+- Bonus: ikona rozwijania breakdown przemodelowana na okragly button (hover, fioletowy stan open, CSS rotate chevron) - usunieto JS swap klas FA.
+
+## Task Commits
+
+Brak commitu fazowego na tym etapie (working tree zawiera tez `.vscode/ftp-kr.sync.cache.json`, `.serena/project.yml` i `.paul/STATE.md` z innych watkow).
+
+## Files Created/Modified
+
+| File | Change | Purpose |
+|------|--------|---------|
+| `autoload/factory/class.Products.php` | Modified (+51) | Nowa metoda `delete_product_scope_history($pid,$cid,$agid)` z transakcja PDO i 3-tabelowym DELETE |
+| `autoload/controls/class.Products.php` | Modified (+23 +3) | Nowa akcja AJAX `delete_product_scope_history()`; payload `breakdown_for_view` rozszerzony o `product_id`, `campaign_id`, `ad_group_id` |
+| `templates/products/main_view.php` | Modified (+86, ~30 styling) | Kolumna "Akcje" w `products_build_breakdown_html`, handler kliku z `$.confirm`, przebudowane style `.products-breakdown-toggle` (CSS rotate zamiast JS), CSS `td:last-child` szerokosci 56px |
+
+## Decisions Made
+
+| Decision | Rationale | Impact |
+|----------|-----------|--------|
+| Eksponowac product/campaign/ad_group ID w `breakdown_for_view` | Bez tego JS dostawal `undefined` ID i handler ucinal sie na walidacji `<= 0` | Ustanawia wzorzec: jak chcesz akcje per-wiersz w child row, dodaj ID do payloadu row_meta |
+| Stylowac chevron rotacja CSS, nie podmiana klas FA w JS | Mniej kodu JS, plynniejsza animacja, jeden zrodlowy stan (`.products-breakdown-open`) | Pojedynczy CSS transition zarzadza wizualem; usunieto 2 linie JS |
+| Transakcja PDO + guard `inTransaction()` zamiast nested-transaction errora | Inny kod moze otworzyc transakcje wczesniej (np. w cron/migracji) | Bezpieczne uzycie metody w roznych kontekstach wywolania |
+
+## Deviations from Plan
+
+### Summary
+
+| Type | Count | Impact |
+|------|-------|--------|
+| Auto-fixed | 1 | Niezbedne - bez tej korekty UI nie dziala (bug: undefined ID) |
+| Scope additions | 1 | Maly bonus stylowania ikony toggle na prosbe usera, w obrebie tego samego pliku |
+| Deferred | 0 | Brak |
+
+**Total impact:** Plan zrealizowany zgodnie z zakresem; jedna konieczna korekta payloadu (Task 2) i jedno male rozszerzenie kosmetyczne na zyczenie usera.
+
+### Auto-fixed Issues
+
+**1. UI Breakdown - brak ID produktu/kampanii/grupy w payloadzie**
+- Found during: Task 4 (human-verify)
+- Issue: `js-products-breakdown-delete` po kliknieciu nie robil nic - `parseInt(undefined,10) || 0` dalo `0`, a handler ma `if (product_id <= 0) return`. Powod: `breakdown_for_view` w `controls/class.Products.php:1097` mapowal tylko statystyki + nazwy, bez ID.
+- Fix: Dodano `product_id`, `campaign_id`, `ad_group_id` jako pierwsze pola mappingu (z fallbackami).
+- Files: `autoload/controls/class.Products.php`
+- Verification: Czesc human-verify - klik kosza po patchu wywoluje dialog z poprawnymi nazwami kampanii/grupy.
+- Commit: TBD (pojedynczy commit fazowy zostanie wykonany w nastepnym etapie)
+
+### Deferred Items
+
+Brak.
+
+## Issues Encountered
+
+| Issue | Resolution |
+|-------|------------|
+| Klik w kosz nie wywolywal dialogu (puste dane w `entry.product_id` itd.) | Zlokalizowano: payload breakdown filtrowany w controllerze. Dolozono 3 pola ID i pominieto cache state DataTables (force reload) |
+
+## Next Phase Readiness
+
+**Ready:**
+- Wzorzec dla operacji per-wiersz w breakdown ustanowiony (ID w row_meta).
+- Wzorzec transakcyjnego DELETE w factory ustanowiony.
+- Style toggle bardziej spojne wizualnie - mozna wykorzystac wzorzec rotate-on-state w innych collapsible UI.
+
+**Concerns:**
+- Cron sync moze ponownie zaciagnac dane jezeli produkt nadal aktywny w MC dla danej kampanii/grupy - to jest oczekiwane zachowanie, ale uzytkownik powinien byc tego swiadom.
+- Working tree zawiera zmiany niepowiazane z planem (`.vscode/ftp-kr.sync.cache.json`, `.serena/project.yml`) - przy commit fazowym selektywne stage'owanie.
+
+**Blockers:**
+- Brak.

+## Goal
+Dodać obsługę feedu XML (Google Merchant) per klient: pole `xml_feed_url` w edycji klienta, parser XML odporny na duże feedy (kilka tysięcy pozycji), integrację z `cron_universal` która wzbogaca tabelę `products` o dane z feedu (title, description, price, custom_label_1) oraz dodaje nowe rekordy dla pozycji nieobecnych w Google Ads. Dodatkowo: refaktor schematu `products` — rename `name` → `title`, `title` → `title_gmc`, nowe pole `description_gmc` (rozdział danych z feedu od edytowanych/AI).
+
+## Purpose
+Klient ma jedno źródło prawdy o swoich produktach (feed XML producenta). Obecnie dane w `products` pochodzą wyłącznie z Google Ads i Merchant API i są ubogie. Wzbogacenie ich o feed pozwoli na: (1) trafniejsze sugestie AI dla title/description, (2) widoczność produktów spoza GA w panelu, (3) świeże ceny i custom_label_1 do segmentacji.
+
+## Output
+- Migracja SQL dodająca/renamująca kolumny i pole `xml_feed_url` w `clients`
+- Service `\services\XmlFeedImporter` (streaming XMLReader, batched upserts)
+- Hook w `Cron::cron_universal` wywołujący importer po sync produktów GA
+- Pole `xml_feed_url` w dialogu edycji klienta (`templates/clients/main_view.php` + `controls/Clients.php`)
+- Wszystkie odwołania do `products.name` / `products.title` zaktualizowane do nowej semantyki
+</objective>
+
+<context>
+<clarifications>
+- **Pole feed XML** — Jak przechowywać URL feedu XML w bazie?
+  → Odpowiedź: Jedno pole `xml_feed_url` w tabeli `clients` (jeden feed na klienta).
+- **Mapowanie** — Po czym łączyć wpisy z feedu z produktami w bazie?
+  → Odpowiedź: Po `<g:id>` = `products.product_id` (standardowy mapping GMC).
+- **Zakres pól** — Które pola z feedu XML uzupełniać w `products`?
+  → Odpowiedź: `title`, `description` (rozdzielone od pola edytowalnego/AI — osobne `title_gmc` jeśli kolizja, `description_gmc` jako nowe pole), `custom_label_1`, `price`. Brakujące kolumny dorobić.
+- **Rename schematu** — wymaganie dodatkowe z odpowiedzi:
+  → `products.name` → `products.title` (rename). Stare `products.title` (z GMC API) → `products.title_gmc`. Wszystkie miejsca w kodzie, gdzie te kolumny występują, mają zostać zaktualizowane.
+- **Brakujące w GA** — Co robić z pozycjami feedu nieobecnymi w `products`?
+  → Odpowiedź: Dodawać nowe rekordy do `products`.
+- **Skala** — wymaganie odporności:
+  → Pobieranie musi działać dla feedów z kilkoma tysiącami produktów (streaming parser, brak ładowania całego XML do pamięci, batched insert/update, transakcje per batch, timeout-safe wznawianie).

+
+## AC-1: Schemat bazy danych
+```gherkin
+Given klient ma w UI dialog edycji
+When wykonam migrację 029
+Then tabela `clients` zawiera kolumnę `xml_feed_url VARCHAR(500) NULL`
+And tabela `products` zawiera kolumny: `title` (po rename z `name`), `title_gmc` (po rename ze starego `title`), `description_gmc TEXT NULL`, `price DECIMAL(10,2) NULL`
+And istniejący `custom_label_1` pozostaje bez zmian
+And migracja jest idempotentna (drugie uruchomienie nie zmienia stanu)
+```
+
+## AC-2: Edycja klienta — pole feed XML
+```gherkin
+Given otwieram dialog edycji klienta w `/clients`
+When wpisuję URL `https://pomysloweprezenty.pl/google-feed.xml` w polu "XML Feed URL" i zapisuję
+Then wartość trafia do `clients.xml_feed_url`
+And po ponownym otwarciu dialogu pole jest wypełnione
+And puste pole zapisuje NULL (czyści feed)
+```
+
+## AC-3: Cron pobiera feed XML i wzbogaca products (odporność na 1000+ pozycji)
+```gherkin
+Given klient ma ustawiony `xml_feed_url`
+When uruchamia się `cron_universal` dla tego klienta
+Then `\services\XmlFeedImporter::import_for_client($client_id)` wykonuje się po sync produktów GA
+And feed jest parsowany strumieniowo (XMLReader) bez ładowania całości do pamięci
+And produkty są upsertowane w batchach (np. 200 wierszy per batch) w transakcjach
+And dla pozycji `<g:id>` istniejącej w `products.product_id` aktualizowane są pola: `title_gmc`, `description_gmc`, `custom_label_1`, `price`
+And dla pozycji nieistniejącej tworzony jest nowy rekord w `products` (z `client_id`, `product_id` = `<g:id>`, oraz pola jak wyżej)
+And `products.title` i `products.description` (edytowalne/AI) NIE są nadpisywane
+And błąd parsowania pojedynczej pozycji nie przerywa importu (log + skip)
+And do `cron_sync_status` lub `settings` zapisywany jest timestamp ostatniego importu per klient
+And import limity czasu/pamięci PHP są respektowane (max execution time bumped lokalnie, set_time_limit, gc_collect_cycles co batch)
+```
+
+## AC-4: Refaktor odwołań do `name` / `title` w kodzie
+```gherkin
+Given migracja 029 zmienia nazwy kolumn
+When wszystkie pliki PHP/template są zaktualizowane
+Then żadne zapytanie SQL ani odwołanie tablicowe nie używa `products.name` ani starego znaczenia `products.title`
+And widok `/products` (templates/products/main_view.php) renderuje `title` (dawne `name`) jako głównej nazwy
+And widok historii produktu pokazuje również `title_gmc` jeśli różny od `title`
+And edycja produktu w `controls/Products.php` zapisuje do nowych kolumn

+       Lepsze podejście (kolejność krytyczna):
+       - Jeśli `products.title` istnieje I `products.title_gmc` NIE istnieje → `ALTER TABLE products CHANGE title title_gmc VARCHAR(255) NULL DEFAULT NULL`.
+       - Jeśli `products.name` istnieje I `products.title` NIE istnieje (po poprzednim renamie) → `ALTER TABLE products CHANGE name title VARCHAR(255) NULL DEFAULT NULL`.

+  <files>autoload/services/class.XmlFeedImporter.php, autoload/controls/class.Cron.php</files>
+  <action>
+    1. Stwórz `autoload/services/class.XmlFeedImporter.php` (namespace `services`):
+
+       Sygnatura: `static public function import_for_client( int $client_id ): array` — zwraca raport `[ 'fetched' => N, 'updated' => N, 'inserted' => N, 'skipped' => N, 'errors' => [] ]`.
+
+       Implementacja:
+       - Pobierz `clients.xml_feed_url` przez `$mdb -> get('clients', ['xml_feed_url'], ['id' => $client_id])`. Jeśli puste → return z `skipped_reason = 'no_feed'`.
+       - Pobierz feed do pliku tymczasowego (`tempnam(sys_get_temp_dir(), 'xmlfeed_')`) cURL-em ze streamingiem (`CURLOPT_FILE`, `CURLOPT_TIMEOUT = 300`, follow redirects, user-agent). Dla feedów >50MB nie ładuj do pamięci.
+       - Otwórz `XMLReader::open($tmp)`. Iteruj po elementach `<item>` (lub `<entry>` w Atom — wykryj namespace).
+       - Dla każdego `<item>` zbuduj asocjację z odczytu `expand()` → SimpleXMLElement → wyciągnij: `g:id`, `title`, `description`, `g:price`, `g:custom_label_1` (z namespace `g:` zarejestrowanym jako `http://base.google.com/ns/1.0`).
+       - Buforuj wpisy w tablicy `$batch` o rozmiarze 200; po osiągnięciu limitu wykonaj UPSERT batch:
+         - `INSERT INTO products (client_id, product_id, title_gmc, description_gmc, custom_label_1, price, created_at) VALUES (...), (...), ... ON DUPLICATE KEY UPDATE title_gmc = VALUES(title_gmc), description_gmc = VALUES(description_gmc), custom_label_1 = COALESCE(VALUES(custom_label_1), custom_label_1), price = VALUES(price)`.
+         - Wykonaj w transakcji `$mdb->pdo->beginTransaction()` / `commit()`. Przy błędzie batchu — rollback, log i kontynuuj.
+       - WAŻNE: nie nadpisuj pól `title` ani `description` (edytowalne/AI). Tylko `_gmc` warianty.
+       - WAŻNE: warunek `ON DUPLICATE KEY` wymaga UNIQUE INDEX na `(client_id, product_id)`. Zweryfikuj że istnieje (z migracji 016/006); jeśli nie, dodaj go w migracji 029.
+       - Po pętli: `gc_collect_cycles()`, usuń plik tymczasowy, zapisz `clients.xml_feed_last_sync_at = NOW()`.
+       - `set_time_limit(600)` na początku, ini_set memory_limit 512M lokalnie.
+       - Każdy złapany Exception z parsowania pojedynczego itemu → log do `errors[]`, `skipped++`, kontynuuj.
+
+    2. `autoload/controls/class.Cron.php` — w `cron_universal()`:
+       - Po wywołaniu `sync_products_fetch_for_client` (ok. linia 116) dla każdego klienta dodaj:
+         ```php
+         if ( !empty( $client['xml_feed_url'] ) )
+         {
+           $xml_sync = \services\XmlFeedImporter::import_for_client( (int) $client['id'] );
+           // dołącz $xml_sync do raportu / cron_sync_status
+         }
+         ```
+       - Upewnij się, że SELECT klientów w cronie zwraca pole `xml_feed_url`.
+       - Loguj wynik do `logs` (analogicznie do innych sync) oraz aktualizuj `cron_sync_status` jeśli stosowne.
+
+    Avoid:
+      - `simplexml_load_file()` na całym feedzie (eksploduje pamięć dla 5000+ pozycji).
+      - DOMDocument ładowany w całości — to samo.
+      - Brak transakcji na batchach (przy padzie cron zostawi pół-zapisany stan).
+      - Nadpisywanie `products.title` / `products.description` (to są pola edytowalne/AI, kontrolowane przez użytkownika).

+
+**Klient moze podac URL feedu XML w panelu edycji; cron_universal pobiera go strumieniowo (XMLReader, batche 200 w transakcjach), wzbogaca tabele products o title/description/price/custom_label_1, a schemat products zostal rozdzielony na pola zrodlowe (title/description) i edytowalne dla supplemental feed (title_gmc/description_gmc).**

+## Acceptance Criteria Results
+
+| Criterion | Status | Notes |
+|-----------|--------|-------|
+| AC-1: Schemat bazy danych | Pass | Migracja 029 idempotentna; kolumny title/title_gmc/description_gmc/price + xml_feed_url/xml_feed_last_sync_at; INDEX zamiast UNIQUE z powodu legacy duplikatow |
+| AC-2: Edycja klienta — pole feed XML | Pass | Pole "XML Feed URL" w dialogu edycji + walidacja FILTER_VALIDATE_URL + prefill z `data.xml_feed_url` |
+| AC-3: Cron pobiera feed XML i wzbogaca products | Pass | XmlFeedImporter::import_for_client wywolywany w cron_universal; manual upsert (SELECT IN + UPDATE/INSERT); transakcje per batch; ON ERROR pojedynczego itemu - skip+log |
+| AC-4: Refaktor odwolan do name/title | Pass | Wszystkie p.name -> p.title; p.title -> p.title_gmc; aliasy AS name zachowane; is_product_core_field ma title_gmc/description_gmc; lint PHP czysty |
+
+## Accomplishments
+
+- **Schemat products przemodelowany** na czysty source/edit split: `title`+`description` to zrodlowe pola wypelniane przez feed XML lub pierwszy fetch GA; `title_gmc`+`description_gmc` to pola edytowane przez UI/AI i wysylane do GMC przez SupplementalFeed.
+- **Odporny importer feedu XML** — XMLReader streaming bez ladowania calego pliku do pamieci, batche po 200 pozycji w transakcjach, manual upsert kompatybilny z legacy duplikatami `(client_id, offer_id)`, set_time_limit(600), memory_limit 512M, gc_collect_cycles co batch.
+- **UI edycji klienta** uzupelnione o pole `XML Feed URL` (typ `url`, walidacja serwerowa) bez nowych zaleznosci frontendowych.
+- **Cron_universal** automatycznie pobiera feed po sync produktow GA dla kazdego klienta z ustawionym `xml_feed_url`; raport `xml_feed: { fetched, updated, inserted, skipped, peak_memory_mb, duration_ms }` dolaczony do response cron-a.

+
+## Decisions Made
+
+| Decision | Rationale | Impact |
+|----------|-----------|--------|
+| title/description = zrodlo, title_gmc/description_gmc = edycja | Korekta semantyki w trakcie checkpointa - pierwotna interpretacja byla odwrotna. Edytor pisze do _gmc, supplemental feed czyta z _gmc i pcha do GMC | Cala logika edycyjna i sync GMC zostaly zaktualizowane konsekwentnie; XmlFeedImporter pisze do title/description |
+| INDEX zamiast UNIQUE na (client_id, offer_id) | Istniejace dane mialy duplikaty (np. '2-1625' x N), UNIQUE rzucal 1062 IntegrityViolation | Manual upsert w PHP zamiast ON DUPLICATE KEY UPDATE; legacy duplikaty sa wszystkie aktualizowane (lista id z SELECT IN) |
+| Manual SELECT IN + UPDATE/INSERT per batch | Konsekwencja braku UNIQUE; daje pelna kontrole nad obsluga duplikatow | Jeden SELECT + N UPDATE/INSERT per batch w transakcji - wciaz wydajne dla 5000+ pozycji |
+| Aliasy `... AS name` w SELECTach zachowane | Kontrakt z DataTables/JS w templates/products | Brak zmian frontendu; minimalny blast radius |
+
+## Deviations from Plan
+
+### Summary
+
+| Type | Count | Impact |
+|------|-------|--------|
+| Auto-fixed | 3 | Konieczne korekty - migracja UNIQUE -> INDEX, semantyka pol, brakujacy api.php |
+| Scope additions | 0 | Brak |
+| Deferred | 1 | Backfill description -> description_gmc nieobligatoryjny |
+
+**Total impact:** Korekty kierunkowe (semantyka pol + UNIQUE -> INDEX), bez scope creep.
+
+### Auto-fixed Issues
+
+**3. [Coverage] api.php nie byl uwzgledniony w pierwotnym refaktorze**
+- **Found during:** post-checkpoint pytanie uzytkownika ("Czy w api.php rowniez poprawiles nazwy kolumn?")
+- **Issue:** Plan boundaries i grep nie obejmowaly `api.php` - 4 zapytania SQL na `products` z `p.name`/`p.title`, oraz `set_product_data($product['id'], 'title', ...)` w endpointcie product_title_set
+- **Fix:** Wszystkie zapytania zaktualizowane analogicznie do reszty kodu: `p.name` -> `p.title`, `p.title` -> `p.title_gmc`, aliasy `AS name`/`AS title` dodane gdzie publiczny kontrakt API (offer_id/get_default_titles endpointy); `set_product_data` zapisuje teraz do `title_gmc`
+- **Files:** `api.php`
+- **Verification:** lint PHP czysty; grep `p\.name\|p\.title\b` zwraca tylko legalne aliasy
+
+**1. [Schema] UNIQUE INDEX (client_id, offer_id) blokowal migracje przez legacy duplikaty**
+- **Found during:** human-verify checkpoint (php install.php zwrocil SQLSTATE 23000 / 1062 'Duplicate entry 2-1625')
+- **Issue:** Istniejace dane w `products` mialy wiele wierszy z tym samym `(client_id, offer_id)`
+- **Fix:** Zamiana na non-unique INDEX `idx_products_client_offer` + przepisanie XmlFeedImporter::flush_batch z `ON DUPLICATE KEY UPDATE` na manual SELECT-then-UPDATE/INSERT (aktualizuje WSZYSTKIE legacy duplikaty per offer_id)
+- **Files:** `migrations/029_products_rename_columns_and_xml_feed.sql`, `autoload/services/class.XmlFeedImporter.php`
+- **Verification:** `php install.php` przechodzi; importer testowo dziala na klientach z xml_feed_url
+
+**2. [Semantics] Inwersja zrodlo vs edycja w polach title/description**
+- **Found during:** uwaga uzytkownika podczas Task 4 ("title/description = zrodlo, title_gmc/description_gmc = edycja")
+- **Issue:** Pierwotny plan zaklada title=glowny display, title_gmc=zrodlo z feedu - co odwrocilo by przeplyw
+- **Fix:** Flip: XmlFeedImporter pisze do title/description; is_product_core_field = title_gmc/description_gmc; SupplementalFeed czyta z _gmc; controls/Products.php: edycja zapisuje do _gmc; AI prompt context czyta z _gmc
+- **Files:** `autoload/factory/class.Products.php`, `autoload/controls/class.Products.php`, `autoload/services/class.SupplementalFeed.php`, `autoload/services/class.XmlFeedImporter.php`
+- **Verification:** lint PHP czysty wszedzie; flow source -> edit -> GMC zgodny z modelem mentalnym
+
+### Deferred Items
+
+- **Backfill istniejacych edycji do _gmc:** stare wartosci `description` (mieszane: GMC source + uzytkowe edycje) pozostaja w `description`. Jesli historyczne edycje powinny migrowac do `description_gmc`, wymagany jest dodatkowy `UPDATE products SET description_gmc = description WHERE description_gmc IS NULL`. Pozostawione decyzji uzytkownika - brak autoryzacji w planie.
+
+## Issues Encountered
+
+| Issue | Resolution |
+|-------|------------|
+| `php install.php` -> SQLSTATE 23000 (1062) na uk_products_client_offer | Zamiana UNIQUE -> non-unique INDEX + manual upsert w PHP |
+| Niejednoznacznosc semantyki title vs title_gmc po pierwszym renamie | Korekta po uwadze uzytkownika - flip: title=zrodlo, _gmc=edycja, sciagniete na cale stos |
+
+## Next Phase Readiness
+
+**Ready:**
+- Schemat `products` rozdziela source/edit - przyszle integracje feedow (np. inne formaty, multi-feed) maja czytelny target
+- `\services\XmlFeedImporter` jako referencyjny wzorzec importera feedow (XMLReader + batched transactions)
+- Cron pipeline ma jednolity hook point dla wzbogacania danych produktow
+
+**Concerns:**
+- Legacy duplikaty `(client_id, offer_id)` w `products` nie sa rozwiazywane przez ten plan - importer aktualizuje wszystkie wiersze z danym offer_id, ale uklad bazy pozostaje "smieciowy". Przyszle zadanie deduplikacji powinno przeniesc historie/agregaty na pojedynczy id przed wymuszeniem UNIQUE.
+- Pole `description` istnialo wczesniej i moglo zawierac edycje uzytkownika - po nowej semantyce te dane reprezentuja "zrodlo", co moze byc mylace dla starych klientow. Backfill -> description_gmc jest deferred.
+
+**Blockers:** None.
