Merge branch 'develop'

After every develop→main merge, reads the version tag from index.html
(e.g. v1.7.13), checks if that tag already exists, and creates a new
GitHub Release if not. Body is pulled from CHANGELOG.md.

This powers the in-app update badge (`check_update` action) so
self-hosted Docker users see a notification when a new version is
available.

+## [1.7.13] - 2026-05-16
+
+### Fixed
+- **Fresh-install crash: `no such column: undone`** — The `transactions` table was created in `initializeDB()` without the `undone` column, but the composite index `idx_transactions_pid_type_undone` immediately referenced it, crashing every new installation at first DB access.  Added `undone INTEGER DEFAULT 0` to the transactions schema in `initializeDB()`.
+- **Race condition: `duplicate column name: package_unit`** — Concurrent API requests on a new installation could all pass the `PRAGMA table_info` guard simultaneously and each try to `ALTER TABLE products ADD COLUMN package_unit`, with all but the first failing with a PDOException.  Wrapped all `ALTER TABLE … ADD COLUMN` calls in try/catch to silently ignore duplicate-column errors.
+
 ## [1.7.12] - 2026-05-13
 
 ### Fixed
-- **Banner "Usa prima" con data calcolata confusa** — `_renderUseExpiryHint` mostrava una data di scadenza *calcolata* (shelf life dopo apertura) anziché la data reale. Ora, se il prodotto ha `opened_at`, il banner mostra "Quella [nel frigo], aperta da X giorni — usala prima!" usando la nuova chiave `use.expiry_warning_opened`.
-- **"Usa TUTTO / Finito" nelle ricette cancellava la riga** — `submitRecipeUse(true)` inviava `use_all: true` all'API che eseguiva un `DELETE` diretto sulla riga di inventario senza conferma. La funzione ora calcola la quantità esatta dagli item disponibili (`_recipeUseContext.items`) e invia un normale `inventory_use` con quantità esplicita.
-- **Ricette: `qty_number` in grammi per prodotti `pz`** — Il prompt AI e la post-elaborazione PHP ora istruiscono Gemini a esprimere `qty_number` come pezzi interi per ingredienti con unità `pz` (Pan bauletto, fette biscottate, ecc.). La lista ingredienti nel prompt include `[usa PEZZI interi]` per ogni prodotto `pz`. Il fallback PHP per `pz` senza `default_quantity` non divide più per 100 (trattando grammi come pezzi), ma usa il `qty_number` restituito dall'AI se sembra un conteggio plausibile, altrimenti 1.
+- **"Use first" banner showed a calculated expiry date** — `_renderUseExpiryHint` was displaying a *calculated* shelf-life date (from opening date) instead of the actual one. When `opened_at` is set, the banner now shows "That one [in the fridge], opened X days ago — use it first!" using the new `use.expiry_warning_opened` translation key.
+- **"Use All / Done" in recipes deleted the inventory row** — `submitRecipeUse(true)` was sending `use_all: true` to the API, which executed a direct `DELETE` on the inventory row without any confirmation. The function now calculates the exact quantity from the available items (`_recipeUseContext.items`) and sends a regular `inventory_use` with an explicit quantity.
+- **Recipes: `qty_number` returned in grams for piece-counted (`pz`) items** — The AI prompt and PHP post-processing now instruct Gemini to express `qty_number` as whole pieces for ingredients with unit `pz` (sliced bread, crackers, etc.). The ingredient list in the prompt includes `[use whole PIECES]` for each `pz` product. The PHP fallback for `pz` items without `default_quantity` no longer divides by 100, but uses the AI-returned `qty_number` if it is a plausible count, otherwise defaults to 1.
 
 ### Added
-- **Traduzione `use.expiry_warning_opened`** — Nuova chiave in `it.json`, `en.json`, `de.json` con placeholder `{loc}` (posizione) e `{when}` (giorni dall'apertura).
+- **Translation key `use.expiry_warning_opened`** — New key in `it.json`, `en.json`, `de.json` with `{loc}` (location) and `{when}` (days since opening) placeholders.
 
 ## [1.7.11] - 2026-05-12
 
 ### Added
-- **Scan page redesign** — La pagina di scansione è stata completamente ridisegnata per tablet e mobile:
-  - **2× zoom fisso** — zoom hardware se disponibile, altrimenti CSS `scale(2)` automatico.
-  - **Torcia** — bottone nel viewport con feedback toast e stato visivo.
-  - **Flip fotocamera** — switch front/back con persistenza in settings.
-  - **3 tab input** — Barcode / Nome / AI per un accesso rapido a ciascuna modalità.
-  - **Prodotti recenti** — chip degli ultimi 6 prodotti scansionati (localStorage), con icona categoria.
-  - **Live code overlay** — codice barcode rilevato parzialmente mostrato in sovrimpressione nel viewport.
-  - **Confirm overlay** — checkmark + nome prodotto per 900ms al riconoscimento avvenuto.
-  - **Angoli guida** — frame visivo per inquadrare il barcode.
-  - **AI Number OCR** — dopo 4s senza scansione, compare il bottone "Leggi numeri con AI": Gemini analizza l'immagine e legge le cifre del barcode anche se non viene letto otticamente.
-- **PHP `gemini_number_ocr`** — Nuovo endpoint POST; accetta un'immagine JPEG base64, chiede a Gemini di individuare il codice EAN-13 / EAN-8 stampato sul prodotto, e restituisce le cifre o `not_found`.
+- **Scan page redesign** — The scanner page has been completely redesigned for tablet and mobile:
+  - **2× fixed zoom** — hardware zoom if available, otherwise automatic CSS `scale(2)`.
+  - **Torch** — in-viewport button with toast feedback and visual state indicator.
+  - **Camera flip** — front/back switch with persistence in settings.
+  - **3 input tabs** — Barcode / Name / AI for quick access to each scanning mode.
+  - **Recent products** — chips for the last 6 scanned products (localStorage), with category icon.
+  - **Live code overlay** — partially detected barcode shown as overlay in the viewport during partial scan.
+  - **Confirm overlay** — checkmark + product name displayed for 900 ms on successful recognition.
+  - **Guide corners** — visual alignment frame for barcode centering.
+  - **AI Number OCR** — after 4 s without a scan, a "Read numbers with AI" button appears; Gemini analyses the video frame and returns barcode digits even when the optical scanner fails.
+- **PHP `gemini_number_ocr` endpoint** — New POST endpoint; accepts a base64 JPEG image, asks Gemini to locate the EAN-13 / EAN-8 code printed on the product, and returns the digits or `not_found`.
 
 ### Fixed
-- **Falsi positivi anomalia consumo "Mozzarella 3 pezzi"** — Rimossa la direzione `untracked` (consumo maggiore degli acquisti registrati) che generava banner su ogni prodotto con acquisti non tracciati. Ora vengono segnalate solo le anomalie `phantom` e `missing`.
-- **Predizione "~0g/settimana"** — Il modello richiedeva ora min 5 transazioni (era 3) e un arco temporale di almeno 7 giorni; se il consumo predetto è < 15% della baseline viene saltato, eliminando i falsi positivi su prodotti con poche transazioni ravvicinate.
-- **Menu a tendina suggerimenti sul campo Nome (scan)** — Rimosso `list="common-products"` dal campo di input, il datalist non viene più aperto su tablet.
+- **False consumption anomaly positives (e.g. "Mozzarella 3 pcs")** — Removed the `untracked` direction (consumption higher than recorded purchases), which was generating banners for every product with untracked purchase history. Only `phantom` and `missing` anomalies are now reported.
+- **"~0 g/week" consumption prediction** — The model now requires a minimum of 5 transactions (was 3) and a time span of at least 7 days; predictions where consumption is < 15% of the baseline are skipped, eliminating false positives for products with few closely-spaced transactions.
+- **Suggestion dropdown on the Name field (scan page)** — Removed `list="common-products"` from the input field; the datalist is no longer triggered on tablets.
 
 ## [1.7.10] - 2026-05-11
 
 ### Fixed
-- **Banner "Imposta scadenza" non faceva nulla** — `editBannerNoExpiry()` chiamava `openEditInventoryModal()` che non esiste. Corretto in `editInventoryItem()` (la funzione corretta usata da tutti gli altri handler banner). Aggiunto anche il fetch preventivo di `inventory_list` perché `currentInventory` è vuoto sulla dashboard.
-- **"Prodotto non trovato" aprendo modal da banner** — `currentInventory` è sempre vuoto sulla dashboard; il fetch dell'inventario ora avviene prima di aprire la modal (stesso pattern di `editReviewItem` e `weighBannerItem`).
-- **Banner scaduto su latte UHT aperto** — Il testo mostrava "Scaduto!" invece di "Aperto da troppo tempo". Ora i prodotti con `opened_at` mostrano "Aperto da N giorni in [posizione]" sia nel titolo che nel dettaglio del banner.
-- **Shelf life latte generico 4 → 7 giorni** — Il latte senza qualificatori (es. "Latte") veniva trattato come fresco (4 giorni). Il latte fresco è già gestito esplicitamente (`latte fresco/intero/parzial/scremato` → 3gg); il generico ora vale 7 giorni (default UHT). Fix applicato sia in PHP (`database.php`) che in JS (`app.js`).
-- **`opened_at` stale sulle confezioni intere dopo split** — Quando un uso splitta la riga in "confezioni intere + frazione aperta", la riga delle intere non azzerava `opened_at`. Ora tutti e 3 i percorsi di split eseguono `opened_at = NULL` sulla riga sigillata.
-- **`inventory_update` non registrava transazioni** — La modal di modifica quantità aggiornava l'inventario senza creare transazioni. La differenza viene ora registrata automaticamente come `'in'` o `'out'` con nota `[Correzione manuale]`, evitando falsi positivi nel rilevatore di anomalie.
-- **False anomalie di consumo dopo la spesa** — La baseline della prediction usava solo la quantità del rifornimento (`restockQty`), ignorando le scorte preesistenti → `actual > expected` sistematicamente. Nuova baseline: `qty_attuale + consumato_da_ultimo_rifornimento`, che riflette correttamente la realtà indipendentemente dalle scorte pregresse.
-- **Banner "consumo anomalo" su quasi tutti i prodotti** — Due fix:
-  1. `expected = 0` non genera più anomalia "more" (il modello pensa che dovresti aver finito, ma hai ricomprato).
-  2. Soglia "more than expected" alzata al 400% (era 30%); "less than expected" rimane al 30%.
-- **Sezione scaduti mostra prodotti già buttati** — La query `expired` mancava di `AND i.quantity > 0`; i prodotti buttati (qty=0) con scadenza passata continuavano ad apparire. Corretta la query + pulizia righe orfane nel DB.
-- **Hardcoded `scade il` in banner** — Stringa italiana hardcodata nel dettaglio del banner scaduti rimossa.
-- **Docker: `SQLSTATE[HY000][14] unable to open database file`** — Aggiunta `_ensureDataDir()` in `database.php` che crea la directory se mancante e tenta `chmod(0775)` se non scrivibile.
+- **"Set expiry" banner did nothing** — `editBannerNoExpiry()` was calling `openEditInventoryModal()` which does not exist. Fixed to call `editInventoryItem()` (the correct function used by all other banner handlers). Added a prefetch of `inventory_list` because `currentInventory` is empty on the dashboard.
+- **"Product not found" when opening modal from a banner** — `currentInventory` is always empty on the dashboard; the inventory fetch now happens before opening the modal (same pattern as `editReviewItem` and `weighBannerItem`).
+- **Expired banner on opened UHT milk** — The banner was showing "Expired!" instead of "Opened too long". Items with `opened_at` now display "Opened X days ago in [location]" in both the title and the banner detail.
+- **Generic milk shelf life 4 → 7 days** — Milk without qualifiers (e.g. "Milk") was treated as fresh (4 days). Fresh milk is still handled explicitly (`latte fresco/intero/parzial/scremato` → 3 days); the generic case now defaults to 7 days (UHT default). Fix applied in both PHP (`database.php`) and JS (`app.js`).
+- **Stale `opened_at` on sealed packages after split** — When a use operation splits a row into "whole sealed packages + opened fraction", the sealed-packages row was not clearing `opened_at`. All 3 split code paths now execute `opened_at = NULL` on the sealed row.
+- **`inventory_update` was not recording transactions** — The quantity-edit modal updated inventory without creating transaction records. The quantity difference is now automatically recorded as `in` or `out` with a `[Manual correction]` note, preventing false positives in the anomaly detector.
+- **False consumption anomalies after restocking** — The prediction baseline was using only the restock quantity (`restockQty`), ignoring pre-existing stock, causing `actual > expected` systematically. New baseline: `current_qty + consumed_since_last_restock`, which correctly reflects the real situation regardless of prior stock levels.
+- **Anomaly banner firing on almost all products** — Two fixes:
+  1. `expected = 0` no longer generates a "more" anomaly (the model assumed you should have run out, but you restocked).
+  2. "More than expected" threshold raised to 400% (was 30%); "less than expected" threshold remains at 30%.
+- **Expired section showing already-discarded products** — The `expired` query was missing `AND i.quantity > 0`; discarded products (qty=0) with a past expiry kept appearing. Query fixed and orphan rows cleaned from the DB.
+- **Hardcoded Italian string `scade il` in banner** — Replaced with the correct i18n key.
+- **Docker: `SQLSTATE[HY000][14] unable to open database file`** — `_ensureDataDir()` in `database.php` now creates the `data/` directory if missing and attempts `chmod(0775)` if not writable, resolving the error on freshly mounted Docker volumes.
 
 ### Added
-- **i18n completa** — Aggiunti ~25 chiavi di traduzione mancanti per UI kiosk, gemini, banner, scanner, shopping, appliances in tutti e 3 i file (`it.json`, `en.json`, `de.json`). Totale: 934 chiavi per lingua.
-
-
-### Added
-- **Category badge on inventory items** — Every product in the inventory now displays a macro-category badge (icon + label) next to the location badge. Badges showing `altro` are asynchronously refined via the new `guess_category` AI endpoint (Gemini + `data/category_ai_cache.json` cache) so the correct category appears automatically after the page loads.
-- **Category search** — The inventory search bar now matches items by category. Typing "biscotti" returns every cookie/biscuit regardless of brand or exact name; the match uses both the direct category key and the translated label.
-- **Brand map in `guessCategoryFromName`** — A fast-path brand table (Oreo, Ringo, Uno, Barilla, De Cecco, Galbani, Mutti, Lavazza, etc.) provides instant category resolution before any regex evaluation.
-- **PHP `guess_category` endpoint** — New server-side action that calls Gemini to classify a product name into a local category key, with file-based caching (`data/category_ai_cache.json`). Returns `altro` immediately when no Gemini API key is configured.
-
-### Fixed
-- **Duplicate banner alerts** — `loadBannerAlerts()` was occasionally enqueuing the same item multiple times when called concurrently. Fixed with a `_bannerLoading` re-entrancy guard and a `_queuedItemIds` Set that prevents any item from being pushed more than once per refresh cycle.
-- **`mapToLocalCategory` with `en:dairies` / `en:dairies-and-eggs`** — The dairy regex was not matching OpenFoodFacts tags that use the `dairi` stem; extended to cover the full range of dairy tags.
-- **`mapToLocalCategory` always returning `altro`** — When the input category was already `altro`, the function exited the direct-match loop before attempting any fallback, losing all name-based guesses. The loop now skips the `altro` key for the early-return and falls back to `guessCategoryFromName(productName)` at the end.
-- **"Tonno all'olio" → condimenti** — `tonno\b` was matched after `olio\b` (condimenti) due to regex ordering. Moved the conserve block before the condimenti block so tuna products resolve correctly.
-
-### Security
-- **AI function guards** — All Gemini-powered functions now check `_geminiAvailable` (JS) or the presence of `GEMINI_API_KEY` (PHP) before executing. Affected functions: `_refineCategoryBadgesAsync`, `fetchAllPrices`, `getShoppingPrice`. The PHP endpoint returns `{"success":false,"error":"no_api_key"}` instead of silently returning empty results, making the missing-key state explicit and diagnosable.
+- **Complete i18n** — Added ~25 missing translation keys for kiosk UI, Gemini responses, banners, scanner, shopping, and appliances across all 3 language files (`it.json`, `en.json`, `de.json`). Total: 934 keys per language.
 
 ## [1.7.8] - 2026-05-10
 
 ### Added
-- **Trasferisci a Ricette dalla chat** — Quando la chat con Gemini Chef genera una ricetta, compare il bottone "📥 Trasferisci a Ricette". Premendolo, Gemini converte il testo in JSON strutturato completo (titolo, pasti, ingredienti, passi), il backend arricchisce ogni ingrediente con product_id e location via fuzzy-match (identico a generateRecipe), la ricetta viene salvata in archivio e si apre direttamente nella sezione Ricette con tutti i pulsanti "Usa" e la modalità cottura completa.
-- **Bottone "Apri la ricetta"** — Dopo un trasferimento riuscito, il bottone "📥 Trasferisci a Ricette" si trasforma direttamente in "📖 Apri la ricetta" (stesso elemento DOM), evitando problemi di sovrapposizione.
-- **Crea una ricetta per ingrediente** — Nel pannello azione di ogni alimento in inventario compare il bottone "👨‍🍳 Crea una ricetta con questo" (teal, larghezza piena). Premendolo, Gemini genera una ricetta italiana usando quell'alimento come protagonista (stesso pipeline di chatToRecipe: arricchimento fuzzy-match inventario, meal=null, 8192 token max).
-- **meal non auto-categorizzato** — Le ricette generate da chat o da ingrediente non vengono più auto-categorizzate (meal rimane null); il tag pasto nell'UI viene mostrato solo se valorizzato.
+- **Transfer to Recipes from chat** — When the Gemini Chef chat generates a recipe, a "📥 Transfer to Recipes" button appears. Pressing it triggers Gemini to convert the chat text into a complete structured JSON (title, meal, ingredients, steps); the backend enriches each ingredient with `product_id` and `location` via fuzzy-match (identical to `generateRecipe`); the recipe is saved and opens directly in the Recipes section with all "Use" buttons and full cooking mode.
+- **"Open recipe" button** — After a successful transfer, the "📥 Transfer to Recipes" button transforms into "📖 Open recipe" (same DOM element), preventing overlap.
+- **Create a recipe from an ingredient** — In the action panel of every inventory item, a "👨‍🍳 Create a recipe with this" button appears (teal, full width). Pressing it, Gemini generates a recipe using that ingredient as the star (same pipeline as `chatToRecipe`: inventory fuzzy-match enrichment, `meal=null`, 8192 token max).
+- **Meal not auto-categorized** — Recipes generated from chat or from an ingredient are no longer auto-categorized (`meal` remains null); the meal tag in the UI is only shown when explicitly set.
 
 ### Fixed
-- **Smart shopping: falso positivo "quasi finito"** — Se un prodotto in grammi/ml era quasi esaurito (es. Burro 30g = 12%) ma lo stesso prodotto era disponibile anche come confezione (Burro 1 conf = 99%), il sistema segnalava ugualmente "sta finendo". Ora verifica se la famiglia `shopping_name` ha scorte da altri prodotti: se sì, l'alert viene soppresso. (Esempio: 30g di Burro + 1 conf di Burro → nessun alert.)
-- **Traduzioni JSON corrotte** — La sezione `action` era duplicata nei file `de.json`, `en.json` e `it.json`, causando errori di parsing che bloccavano la CI/CD. Rimossa la sezione spuria.
+- **Smart shopping: false "running low" alert** — If a product in grams/ml was nearly exhausted (e.g. Butter 30 g = 12%) but the same product was also available as a sealed package (Butter 1 pack = 99%), the system still flagged "running low". Now checks whether the `shopping_name` family has stock from other products; if so, the alert is suppressed.
+- **Corrupted translation JSON** — The `action` section was duplicated in `de.json`, `en.json`, and `it.json`, causing JSON parse errors that blocked CI/CD. The spurious duplicate section has been removed.
 
 ## [1.7.7] - 2026-05-10
 
 ### Fixed
-- **Smart shopping family suppression** — La logica `recentlyExhausted` (prodotti terminati < 14gg) bypassava erroneamente anche la suppression per `shopping_name` family, causando falsi positivi: prodotti come Yaourt Vanille apparivano come urgenti anche con 2kg di Yogurt in stock, Salame Paesano con 1kg di Affettato in stock, Gran bauletto rustico con più pani in stock. Ora `recentlyExhausted` bypassa solo il check token-based (match lasco), mentre la family suppression per `shopping_name` si applica sempre.
-- **Shelf life pre-warming nel cron** — Il cron ora chiama `prewarmShelfLifeCache()` ogni 5 minuti, precaricando via Gemini AI la shelf life degli item aperti in inventario (max 5 item per ciclo) prima che l'utente li visualizzi. Questo elimina il delay percepibile al primo click su "Aperto il...".
+- **Smart shopping family suppression** — The `recentlyExhausted` logic (products finished < 14 days ago) was incorrectly bypassing the `shopping_name` family suppression, causing false positives: products like Vanilla Yogurt appeared urgent even with 2 kg of Yogurt in stock. `recentlyExhausted` now only bypasses the token-based loose match; family suppression by `shopping_name` always applies.
+- **Shelf-life pre-warming in cron** — The cron now calls `prewarmShelfLifeCache()` every 5 minutes, pre-loading via Gemini AI the shelf life of opened inventory items (max 5 items per cycle) before the user views them. This eliminates the noticeable delay on first click of "Opened on…".
 
 ## [1.7.6] - 2026-05-10
 
 ### Fixed
-- **`shopping_name` troncato (Piadina)** — Il prodotto "Piadine medie" aveva `shopping_name='Pi'` (troncato), non veniva aggruppato correttamente nella famiglia. Corretto in `Piadina`.
-- **Family merges DB** — Grana Padano ora sotto `Formaggio` (era `Grana` singleton), Prosciutto cotto ora sotto `Affettato`, Panna acida ora sotto `Panna`.
-- **`daily_rate` su periodo effettivo** — Il tasso di consumo giornaliero usava `first_in → now` come finestra, diluendo il rate con periodi in cui il prodotto era già esaurito (es. aglio esaurito a 34gg veniva calcolato su 60+). Ora usa `first_in → last_activity` (ultimo acquisto o ultimo uso), più preciso per le previsioni di riordino.
-- **Anomaly dismiss key stabile** — La chiave di dismiss usava `product_id + round(expected)` che cambiava ad ogni nuova transazione, causando la ricomparsa delle anomalie già chiuse. Ora usa `product_id + direction` (phantom/missing/untracked) — stabile finché la direzione non cambia.
-- **Smart shopping: prodotti esauriti < 14 giorni** — Prodotti terminati negli ultimi 14 giorni non vengono più soppressi dal check token-coverage o shopping_name-family: se li hai appena finiti, è probabile tu voglia ricomprarli indipendentemente dalla presenza di equivalenti in stock.
-- **Chat pruning** — `chatSave()` ora esegue `DELETE` dei messaggi oltre i 200 più recenti dopo ogni salvataggio, evitando crescita illimitata della tabella `chat_messages`.
-- **`getStats()` query consolidate** — Le 5 query separate (COUNT products, SUM inventory, COUNT locations, COUNT recent_in, COUNT recent_out) sono ora una sola query con subselect, riducendo i round-trip SQLite da 5 a 1.
-- **Bring! cleanup rate-limiting** — Aggiunto `usleep(300ms)` tra le rimozioni multiple per evitare di sovraccaricare l'API Bring! in burst.
-- **Indici compositi su `transactions`** — Aggiunti `idx_transactions_type_date(type, created_at)` (per `getStats`) e `idx_transactions_pid_type_undone(product_id, type, undone)` (per `smartShopping`), con migration automatica per DB esistenti.
+- **`shopping_name` truncated (Piadina)** — The product "Piadine medie" had `shopping_name='Pi'` (truncated), preventing it from grouping correctly in its family. Fixed to `Piadina`.
+- **Family merges in DB** — Grana Padano now under `Formaggio` (was a `Grana` singleton), Prosciutto cotto now under `Affettato`, Panna acida now under `Panna`.
+- **`daily_rate` over the actual active period** — The daily consumption rate was using `first_in → now` as the window, diluting the rate with periods when the product was already exhausted (e.g. garlic exhausted at day 34 was calculated over 60+ days). Now uses `first_in → last_activity` (last purchase or last use), giving more accurate reorder predictions.
+- **Stable anomaly dismiss key** — The dismiss key was using `product_id + round(expected)`, which changed with every new transaction, causing already-dismissed anomalies to reappear. Now uses `product_id + direction` (phantom/missing/untracked) — stable as long as the direction does not change.
+- **Smart shopping: products exhausted < 14 days ago** — Products finished within the last 14 days are no longer suppressed by the token-coverage check or the shopping_name family check: if you just ran out, you probably want to restock regardless of equivalent stock on hand.
+- **Chat pruning** — `chatSave()` now deletes messages beyond the 200 most recent after each save, preventing unbounded growth of the `chat_messages` table.
 
-### Security
-- **CSRF protection** — Le action di scrittura (inventory_add, bring_add, product_save, ecc.) richiedono ora `X-EverShelf-Request: 1` oppure `Content-Type: application/json`. Il frontend `api()` invia sempre il header su POST. Questo previene attacchi CSRF cross-site tramite form HTML.

-## 🌍 Recent Updates (v1.7.12)
-
-- **Banner aperto con indicazione posizione** — Nella sezione "Usa prima" il testo ora mostra "Quella nel frigo, aperta da X giorni" invece di una data di scadenza calcolata che poteva risultare confusa.
-- **Ricette: quantità in pezzi per prodotti pz** — Il prompt AI e la post-elaborazione PHP ora istruiscono Gemini a esprimere `qty_number` come pezzi interi (non grammi) per i prodotti con unità `pz` (es. Pan bauletto, fette biscottate). Il fallback PHP non divide più per 100 quando `default_quantity = 0`.
-- **Fix: "Usa TUTTO" nelle ricette non elimina più la riga** — Il pulsante "Usa TUTTO / Finito" nella modal di utilizzo ricette inviava `use_all: true` che causava un `DELETE` immediato senza conferma. Ora calcola la quantità esatta dagli item disponibili e fa un normale `inventory_use`.
-
-- **Scan page redesign** — La pagina di scansione è stata completamente ridisegnata: **2× zoom fisso** (hardware o CSS), **torcia** con feedback visivo, **flip fotocamera** (front/back), **3 tab input** (Barcode / Nome / AI), **prodotti recenti** (ultimi 6 in localStorage), **live code overlay** durante la scansione parziale, **confirm overlay** al successo, **angoli guida** nel viewport.
-- **AI Number OCR** — Dopo 4 secondi senza scansione compare il bottone "Leggi numeri con AI": Gemini analizza il frame video e restituisce le cifre del barcode anche quando lo scanner ottico non riesce a leggerlo.
-- **Fix falsi positivi anomalie** — Rimossa la direzione `untracked` dal rilevatore di anomalie; le predizioni di consumo richiedono ora min 5 transazioni e 7 giorni di storico.
-- **Fix menu suggerimenti scan** — Rimosso il datalist dal campo Nome nella pagina scansione (non più aperto su tablet).
-- **Fix falsi positivi anomalie consumo** — `getConsumptionPredictions` richiedeva solo 3 transazioni, potendo generare rate esplose su dati ravvicinati. Ora: min 5 txn, min 7gg span, skip se consumo predetto < 15% baseline.
-
-- **Banner "Imposta scadenza" ora funziona** — Il pulsante sul banner "nessuna scadenza" apriva una funzione inesistente. Corretto, ora apre correttamente la modal di modifica.
-- **Banner aperto vs scaduto** — I prodotti con `opened_at` mostrano "Aperto da N giorni in [posizione]" invece di "Scaduto!", con la posizione (frigo/dispensa/freezer) esplicitamente indicata.
-- **Shelf life latte UHT** — Il latte generico è ora trattato come UHT (7 giorni dopo apertura) invece che fresco (4 giorni).
-- **Niente più false anomalie di consumo** — Il rilevatore ora ignora i casi in cui `expected = 0` (prodotto probabilmente ricomprato) e alza la soglia "more than expected" al 400%. Le notifiche rimangono solo per consumi significativamente inferiori al previsto.
-- **Scaduti nascondono prodotti già buttati** — La sezione scaduti ora filtra correttamente i prodotti con `quantity = 0`.
-- **Docker: fix permessi DB al primo avvio** — `_ensureDataDir()` crea la directory `data/` se mancante e tenta `chmod(0775)` se non scrivibile, risolvendo `SQLSTATE[HY000][14]` su volumi Docker freschi.
-- **AI price estimation for shopping list** — Each Bring! shopping item now shows an estimated retail price badge (unit price + total). Prices are fetched via Gemini AI, cached server-side for 3 months, and stored client-side in `sessionStorage` to survive navigation. The dashboard shopping stat card shows a live green `ca. €X.XX` badge that updates in real-time as prices are calculated — even in background when you're on another tab.
-- **Kiosk v1.7.0: OTA update system** — "Cerca aggiornamenti" button in Settings triggers a forced GitHub release check; new `installUpdate()` JS bridge calls Android `DownloadManager` directly (lockTask mode blocks external browser links); graceful degradation for older APKs with manual instructions. Automatic OTA check every 6 hours with native update banner.
-- **Kiosk: consistent APK signing** — Project keystore (`evershelf.jks`) committed to the repo; every build — local or CI — now produces an APK with the same signature, eliminating "APK incompatible / signature conflict" errors on OTA update.
-- **GitHub Actions: auto-publish kiosk APK** — On every push to `main` that touches `evershelf-kiosk/`, Actions builds the APK and publishes a versioned semver release (`kiosk-X.Y.Z`) plus updates the `kiosk-latest` alias. No more manual release uploads.
-- **Fix: false "update available" on launch** — `checkForUpdates` now requires a strictly-greater semver tag to flag an update. Non-semver tags (e.g. `kiosk-latest`) no longer trigger a false positive immediately after a fresh install.
-- **Kiosk: live scale diagnostic panel** — When connected, Settings shows device name, battery %, real-time weight, protocol and reconnection status without leaving the settings page.
-- **Kiosk: scale dot visible on header** — Connected-state dot changed from green-on-green to white fill + green glow, clearly visible on any background.
-- **Kiosk: reconfigure BLE scale** — New "Riconfigura bilancia BLE" button in Settings; shows amber notice with download link if the installed APK predates the `reconfigureScale()` bridge method.
-- **Nutrition analysis dashboard** — Category distribution pie chart (3D conic-gradient), health/variety/freshness score bars, alternates with the anti-waste section hourly.
-- **Screensaver nutrition panel** — Animated 3D pie + donut ring scores rotate with fact cards every 5 minutes in the screensaver overlay.
-- **Automatic error reporting** — Unhandled JS errors, Android crashes and PHP exceptions are silently posted to `api/?action=report_error`; the server deduplicates by fingerprint and creates or comments on a GitHub Issue automatically. Crash details are persisted to `SharedPreferences` so even errors that prevent network I/O are sent on the next launch.
-- **Demo mode (JS)** — Full frontend demo with mock pantry data, Gemini enabled, Bring! writes silently no-op'd; accessible via `?demo=1` or `.env` `DEMO_MODE=true`.
-- **Graceful Bring! no-key state** — When Bring! credentials are not configured, the shopping tab shows a friendly message with a direct link to Settings instead of a raw error.
-- **Use-quantity guard** — Consuming more than the stocked quantity at a given location is now blocked client-side with a shake animation on the quantity field.
-- **Kiosk v1.6.0: BLE scale gateway integrated** — The standalone Scale Gateway app is no longer needed. BLE scanning, GATT connection and the WebSocket server (`:8765`) now run as a built-in `GatewayService` foreground service inside the kiosk app. Setup step 4 shows a live BLE device scan — users select their scale directly, no external APK install required. The external gateway app is deprecated.
-- **Kiosk setup wizard overhaul** — Auto-discovery rewritten with `ExecutorCompletionService` + `NetworkInterface` (no deprecated `WifiManager`), 60 parallel TCP pre-checks, real-time UI feedback, ports 80/443/8080/8443, correct LAN subnet detection (VPN/cellular interfaces filtered, `wlan`/`eth` prioritised).
-- **Kiosk permissions flow** — Grant button transforms into a green "✅ Permessi concessi — Continua →" button after permissions are granted instead of just showing a card.
-- **3 new AI features (Gemini)** — Storage/shelf-life hint shown inline in the add form; AI-enriched shopping suggestions with a short practical tip per item; plain-language anomaly explanation via a "🤖 Spiega" button on anomaly banners.
-- **Security hardening** — `get_settings` no longer exposes API keys in plain text (boolean flags only); `save_settings` protected by optional `SETTINGS_TOKEN` (validated with `hash_equals`); native `DEMO_MODE` in `.env` blocks all write operations at the PHP router level before any other guard.
-- **Real-time webapp update detection** — An inline header pill appears when a newer release is on GitHub (checked on load + every 30 min); no intrusive full-page banners.
-- **Gemini availability flag** — All AI entry points check `_geminiAvailable` before firing; the header button shows a visual no-AI state (greyed + amber dot) when no key is configured.
-- **Dashboard skeleton loading** — Stat cards show an animated shimmer while data loads instead of a jarring `0` flash for 3–5 seconds.
-- **APK self-update with conflict recovery** — Both Kiosk and Scale Gateway use the `PackageInstaller` session API for OTA installs; a signature conflict now shows a dialog to uninstall the old version instead of a cryptic failure.
-- **Smarter low-quantity alerts** — The "suspiciously low quantity" banner is no longer raised for a partially-used entry when the same product has stock in another location.
-- **Non-alarmist expired banner** — Adapts icon, colour, and title to the actual safety level: green ✅ for long-life products still safe, amber 👀 for items to check, red 🚫 only for genuinely dangerous items.

+### High Priority
+- [ ] **Cooking mode — 3D wheel JS** — swipe navigation, gyroscope tilt, haptic feedback
+- [ ] **Cooking mode — step timers** — auto-detect "X minutes" in recipe steps, countdown + alert
+- [ ] **Push notifications** — daily expiry alerts via PWA Service Worker + VAPID
+- [ ] **Quick search / quick-add bar** — always-visible search above the nav, PWA shortcuts
+
+### Medium Priority
+- [ ] **Receipt OCR → bulk add** — photo of receipt → Gemini Vision → auto-fill inventory
+- [ ] **CSV/JSON export & import** — download/upload inventory from Settings
+- [ ] **Custom storage locations** — user-defined locations beyond Fridge/Freezer/Pantry
+- [ ] **Multi-user support** — PIN-based user distinction, action log with user label
+- [ ] **AI optimal purchase prediction** — suggest "buy X units of Y within Z days"
+- [ ] **Price history sparklines** — per-product price chart from the AI cache data
+
+### Low Priority / Nice to Have
+- [ ] **Dark mode** — CSS custom properties are already structured to support it
+- [ ] **Full offline mode** — Service Worker cache to show inventory read-only when server is down
+- [ ] **French & Spanish translations** (`fr.json`, `es.json`)
+- [ ] **Swipe actions on inventory rows** — swipe left to use/discard, right to edit
+- [ ] **PHP unit tests** — PHPUnit coverage for shelf-life, price calc, and key helpers
+
+### Completed ✅
+- ✅ AI price estimation in shopping list
+- ✅ Server heartbeat + offline banner
+- ✅ In-app bug reporter → automatic GitHub issue creation
+- ✅ Cooking mode (start, steps, 3D wheel CSS)
+- ✅ Kiosk ⚙️ Settings overlay button (replaces Android native button)
+- ✅ Adaptive consumption anomaly detection
+- ✅ CI/CD pipeline (PHP lint, JS lint, Docker build, Trivy security scan)

+# Security Policy
+
+## Supported Versions
+
+Only the latest released version of EverShelf receives security fixes.
+
+| Version | Supported |
+|---------|-----------|
+| Latest (1.7.x) | ✅ |
+| Older releases | ❌ |
+
+## Reporting a Vulnerability
+
+**Please do NOT open a public GitHub issue for security vulnerabilities.**
+
+Report security issues privately via email:
+
+**📧 evershelfproject@gmail.com**
+
+Include:
+- A description of the vulnerability
+- Steps to reproduce
+- Potential impact
+- Your GitHub username (optional — for credit)
+
+I aim to acknowledge reports within **48 hours** and release a fix within **7 days** for critical issues.
+
+## Scope
+
+EverShelf is a **self-hosted** application. The security model assumes:
+
+- It runs on a trusted private network (home LAN)
+- Access from the internet requires the user to set up their own authentication layer (e.g. reverse proxy with Authelia, Nginx `auth_basic`)
+
+Out-of-scope issues:
+- Vulnerabilities that require physical access to the server
+- Issues only affecting users who have not followed the security recommendations in the README
+- Denial-of-service attacks on the demo server
+
+## Security Features
+
+- API keys stored server-side in `.env`, never sent to the browser
+- `get_settings` returns only boolean flags (`gemini_key_set`), never raw key values
+- Optional `SETTINGS_TOKEN` protects write operations (`hash_equals` to prevent timing attacks)
+- `DEMO_MODE=true` blocks all write operations at the router level
+- Parameterized SQL queries (PDO prepared statements) throughout
+- Input validation and length limits on all user-supplied fields
+- `.env` and `data/` directories denied via web server config (see README)

-# ~~EverShelf Scale Gateway~~ — DEPRECATED
-
-> ⚠️ **This app is deprecated and no longer maintained.**
->
-> As of **EverShelf Kiosk v1.6.0**, BLE scale support is fully integrated into the kiosk app itself. You no longer need to install or configure this separate gateway app.
->
-> **If you are using the EverShelf Kiosk app** → the scale gateway runs automatically as a background service. Configure your Bluetooth scale in **step 4 of the setup wizard**.
->
-> **If you are NOT using the kiosk app** (standalone Android tablet) → you may still use this APK, but no new releases will be published.
-
----
-
-# EverShelf Scale Gateway (legacy)
-
-> Android gateway app that bridges Bluetooth LE smart scales with EverShelf via WebSocket.
-
----
-
-## How it works
-
-```
-Smart Scale ──(BLE)──► Android Gateway App ──(WebSocket/LAN)──► EverShelf Server ──(SSE)──► Browser
-```
-
-The app runs a local WebSocket server (port **8765**) on your Android device. The EverShelf server connects to it via a server-side relay (`api/scale_relay.php` SSE + `api/scale_ping.php` WebSocket client), avoiding mixed-content (HTTPS→WS) issues. Weight readings are streamed to the browser in real time.
-
-> **Kiosk integration (v1.6.0+):** The gateway is now **built into the EverShelf Kiosk app** as a foreground service. This separate app is not needed when using the kiosk.
-
----
-
-## Supported scale protocols
-
-| Protocol | Service UUID | Notes |
-|---|---|---|
-| **Bluetooth SIG Weight Scale** | `0x181D` / char `0x2A9D` | Most compatible; works with most smart scales |
-| **Bluetooth SIG Body Composition** | `0x181B` / char `0x2A9C` | Reports weight + body fat %, BMI |
-| **Generic fallback** | Any notifiable characteristic | Auto-heuristic parsing for 100+ models |
-
-### Verified compatible scales (community list)
-- Xiaomi Mi Body Composition Scale 2
-- Renpho Smart Body Fat Scale
-- INEVIFIT Smart Body Fat Scale
-- Any OpenScale-compatible scale (see [openScale supported devices](https://github.com/oliexdev/openScale/wiki/Supported-scales))
-
-> **Your scale (B09MRXVBV6):** If it implements the standard BLE Weight Scale or Body Composition profile (very likely for modern Amazon smart scales), the gateway will connect automatically. If not, check the [openScale wiki](https://github.com/oliexdev/openScale/wiki/Supported-scales) and open an issue.
-
----
-
-## Download
-
-Download the latest APK directly: **[evershelf-scale-gateway.apk](https://github.com/dadaloop82/EverShelf/releases/latest/download/evershelf-scale-gateway.apk)**
-
----
-
-## Requirements
-
-- Android **7.0** (API 24) or later
-- Bluetooth LE (BLE) support
-- Both the Android device and the device running EverShelf must be on the **same Wi-Fi network**
-
----
-
-## Setup (step by step)
-
-### 1. Install the APK
-Download and install the APK from the Releases page. You may need to allow "Install from unknown sources" in Android settings.
-
-### 2. Launch the app
-The app starts the WebSocket gateway server immediately. You will see the **gateway URL** (e.g. `ws://192.168.1.100:8765`) at the top.
-
-### 3. Connect your scale
-Tap **"Cerca Bilance Bluetooth"** (Find Bluetooth Scales). Make sure your scale is turned on. Tap it in the list to connect.
-
-### 4. Configure EverShelf
-In EverShelf → ⚙️ Settings → **⚖️ Bilancia Smart**:
-1. Enable the toggle
-2. Paste the gateway URL shown in the Android app
-3. Tap **"Testa connessione"** — you should see ✅
-
-### 5. Use it
-When adding or consuming a product with unit **g** or **ml**, a **"⚖️ Leggi dalla bilancia"** button appears. Tap it, place the product on the scale, and the weight is filled in automatically.
-
----
-
-## WebSocket protocol reference
-
-All messages are JSON. The server sends these to connected clients:
-
-```json
-// Scale status update
-{"type":"status","state":"connected","device":"Mi Scale 2","battery":85}
-{"type":"status","state":"disconnected"}
-
-// Weight reading (broadcast continuously while scale is active)
-{"type":"weight","value":72.50,"unit":"kg","stable":true,"timestamp":1712345678000}
-
-// Response to ping
-{"type":"pong"}
-```
-
-Clients can send:
-
-```json
-{"type":"get_status"}   // Request current status
-{"type":"get_weight"}   // Request next stable weight reading
-{"type":"ping"}         // Keep-alive
-```
-
----
-
-## Build from source
-
-### Prerequisites
-- Android Studio Hedgehog (2023.1) or later
-- Java 8+
-
-### Steps
-```bash
-# 1. Clone the repo
-git clone https://github.com/dadaloop82/EverShelf.git
-cd EverShelf/evershelf-scale-gateway
-
-# 2. Download the Gradle wrapper (if not included)
-gradle wrapper --gradle-version 8.4
-
-# 3. Build debug APK
-./gradlew assembleDebug
-
-# APK is at: app/build/outputs/apk/debug/app-debug.apk

- *
- * The token is intentionally hardcoded — it is scoped only to
- * Issues (Read+Write) on this single repository.

- * Usage:
- *   ErrorReporter.init(applicationContext)
- *   ErrorReporter.report(exception, "methodName", mapOf("extra" to "info"))
- *   ErrorReporter.reportMessage("ble-disconnect", "Scale disconnected after 3 retries")
