+## [0.8.0] - 2026-08-27
+
+### Added
+- `Modules\Core\Cart\Filament\Resources\CartResource` gives staff read-only visibility into carts in the Filament admin panel — Lunar ships no cart admin view at all. Scoped to carts with a known `user_id`/`customer_id` (an anonymous guest cart carries no identity staff could act on); list table shows customer/user, line/item counts (via Filament's built-in `->counts()`/`->sum()`, no per-row queries), currency, and last activity. List page has only two tabs, **Abandoned** (default active) and **Completed** — no "All" tab, so the list never runs an unfiltered fetch over the whole table. They key off whether the cart has a **placed** order (`orders.placed_at IS NOT NULL`), not `Cart::completed_at` — that column is declared/cast on the model but never actually written anywhere in Lunar core, so it's not a real signal; "Abandoned" mirrors Lunar's own `Cart::scopeActive()`. `getNavigationBadge()` shows the abandoned-cart count in the sidebar via a single `COUNT(*)` query, no rows loaded. View page runs `$cart->calculate()` once so line/cart totals (plain public properties Lunar never persists) are populated, without paying that cost per row in the list. Documented in `docs/cart.md`.
+
+## [0.7.0] - 2026-08-27
+
+### Added
+- `Modules\Core\Catalog\Services\CollectionService` provides category browsing/nav AND single-collection lookup from Meilisearch, mirroring `ProductService` exactly (`list()`, `getById()`, `getBySlug()`, same locale-resolution logic). `Modules\Core\Catalog\Services\CollectionIndexer` extends Lunar's own `Lunar\Search\CollectionIndexer` (which only carried `id`/`name`/`created_at`) to add `parent_id`, `_lft`/`_rgt` (nested-set tree position, filterable/sortable), `collection_group_id`, `slugs`, and `thumbnail`. `Modules\Core\Catalog\DTOs\CollectionFilters` supports `parentId` (children of a specific collection), `groupId`, and `rootOnly` (top-level collections, `parent_id IS NULL` — mutually exclusive with `parentId`). `Modules\Core\Catalog\Enums\CollectionSort` adds `Position` (`_lft:asc`, the recommended default for nav/tree UIs — matches admin arrangement order), `Name`, `Newest`. Must be registered in a consuming app's `config/lunar/search.php` (`Lunar\Models\Collection::class => CollectionIndexer::class`), same as `ProductIndexer`. Documented in `docs/collections.md`.
+- `Modules\Core\Localization\Services\StorefrontLabels::all()` extracts the default storefront UI label list out of `InstallLunarCommand` into its own class, and adds every previously-missing key (`nav.contact`, `product.description`/`no_image`/`read_more`/`reviews`, `customer_reviews`, `pagination.*`, `review.*`, `shop.*`) that had already been seeded manually in some stores but was absent from the command's own list — bringing the code-side default back in sync with what a real store actually has. `InstallLunarCommand::seedStorefrontLabels()` now does a **per-key upsert** instead of an all-or-nothing "only seed if the group is empty" guard: a key already present in the database (including one an admin has since edited via the Filament **Language Lines** resource) is left untouched, and only missing keys are created via `TranslationService::create()`. This makes it safe to add new keys to `StorefrontLabels::all()` later and re-run `lunar:install` on an already-installed store without either silently skipping the new keys (the old guard's behavior) or reverting an admin's edits back to the hardcoded default. Documented in `docs/localization.md` ("Seeding").
+- `Modules\Core\Catalog\Services\CollectionIndexer` adds `ancestors` — `[{id, name}, ...]` ordered root-first (via the newly eager-loaded `ancestors` relation) — so a breadcrumb can render directly from `CollectionService::getById()`/`getBySlug()` with zero extra queries, and `product_count` — how many products are in a collection or any of its descendants, queried from the product Meilisearch index at collection-index time via the same `collection_ids` field `ProductFilters(collectionId:)` filters against. Documented in `docs/collections.md`, including the reindex-ordering gotcha (`product_count` needs the product index reindexed first).
+- `Modules\Core\Catalog\Services\ProductIndexer` adds a filterable `in_stock` boolean — `true` if any variant currently passes `ProductVariant::canBeFulfilledAtQuantity(1)` (Lunar's own purchasability rule, not a naive `stock > 0` check). `Modules\Core\Catalog\DTOs\ProductFilters` gets a matching `inStockOnly` flag. Reflects stock as of the last reindex only — nothing currently reindexes a product when an order decrements its stock, since that's a cart/checkout concern this doesn't attempt to solve; see `docs/product-listing.md` ("Stock goes stale between orders").
+- `Modules\Core\Catalog\Services\ProductService::facets(string $field, ?ProductFilters $filters = null): array` returns Meilisearch facet value counts (e.g. `['Brand A' => 48, 'Brand B' => 135]`) for a discrete-value filterable field, scoped to the given filters. Uses Scout's plain `->options(['facets' => [...]])`, merged directly into the raw Meilisearch query the same way `filter`/`sort` already are — no adoption of Lunar's separate `SearchManager`/`Search` facade needed. `ProductService::priceRange(?ProductFilters $filters = null): array{min, max}` covers the numeric-field case `facets()` explicitly doesn't (`price` would otherwise return one "facet" per exact price) — backed by Meilisearch's `facetStats`, not `facetDistribution`. `priceRange()` always excludes `minPrice`/`maxPrice` from the filter it builds (via a new `$exclude` parameter on the private `buildFilter()`), so a price slider's own bounds don't shrink to whatever range is already selected on it; other filters (`collectionId`, `brand`, `inStockOnly`) still apply normally. Documented in `docs/product-listing.md`.
+
+### Changed
+- **Breaking:** Renamed the `Product` module to `Catalog`, flattened. Every class under `Modules\Core\Product\*` (`Contracts`, `DTOs`, `Enums`, `Services`, `Observers`, `Filament\Extensions`, `OptionTypes`) now lives under `Modules\Core\Catalog\*` at the same sub-path — e.g. `Modules\Core\Product\Services\ProductService` is now `Modules\Core\Catalog\Services\ProductService`, `Modules\Core\Product\DTOs\ProductFilters` is now `Modules\Core\Catalog\DTOs\ProductFilters`. Class names themselves are unchanged (still `ProductService`, `ProductIndexer`, `ProductFilters`, etc.) — only the namespace/folder moved, to make room for `Collection` as a sibling concern under the same `Catalog` umbrella rather than a disconnected top-level module. Consuming apps must update every `use Modules\Core\Product\...` import and any FQCN reference (`config/lunar/search.php`'s indexer registration, service provider bindings).
+- **Breaking:** `Modules\Core\Providers\ProductServiceProvider` renamed to `Modules\Core\Providers\CatalogServiceProvider` (composer.json's provider list updated accordingly) — it now only wires `Catalog`-namespace classes (`ProductOptionTypeManager`, `ProductOptionReindexObserver`), so the name follows the same by-concern convention as `LocalizationServiceProvider`/`ReviewServiceProvider`.
+- **Breaking:** `Modules\Core\Review`'s flat `Extensions/`/`Pages/` folders now nest under `Filament/`, matching the strict per-concern subfolder convention already applied to `Product`(now `Catalog`)/`Localization`. `Modules\Core\Review\Extensions\ProductResourceExtension` is now `Modules\Core\Review\Filament\Extensions\ProductResourceExtension`; `Modules\Core\Review\Pages\ManageProductReviews` is now `Modules\Core\Review\Filament\Pages\ManageProductReviews`. `Modules\Core\Review\Models\ProductReview` is unchanged.
+- **Breaking:** `ProductFilters(collectionId: ...)` now matches a product in that collection **or any of its descendant collections**, not just direct assignment. Products in a Shopify-imported tree are typically attached only to leaf collections, so filtering strictly on direct assignment meant a parent/root category page (`CollectionFilters(rootOnly: true)`'s results, or any non-leaf collection) always returned zero products even though real products existed several levels down. `Modules\Core\Catalog\Services\ProductIndexer` adds a new filterable `collection_ids` field — every directly-assigned collection's id unioned with all of its ancestors' ids (via the newly eager-loaded `collections.ancestors`) — and `ProductService::buildFilter()` now filters `collectionId` against `collection_ids` instead of the old `collections.id`. The display-only `collections` field (`{id, name}`, direct assignments) is unchanged and no longer filterable.
+
+## [0.6.1] - 2026-08-27
+
+### Added
+- `Modules\Core\Product\Contracts\ProductOptionTypeInterface` describes how a category of `Lunar\Models\ProductOption` (e.g. "Color", "Size") behaves — what structured data its values carry in their free-form `meta` jsonb column, and how an admin edits it via Filament — without introducing a new model. Registered via `Modules\Core\Product\Services\ProductOptionTypeManager::get()->register([...])` (a singleton registry, same shape as `Modules\Core\Notification\NotificationRegistry`) from a service provider's `boot()`. An admin then picks one per `ProductOption` from an "Option Type" dropdown on the option's own edit form (added by `Modules\Core\Product\Filament\Extensions\ProductOptionResourceExtension`), stored in `ProductOption::meta['option_type']` — deliberately not tied to the option's `handle`, since a shop's own handle naming shouldn't have to match a type's key. `Modules\Core\Product\Filament\Extensions\ValuesRelationManagerExtension` hooks Lunar's own `ValuesRelationManager` (both extensions via `LunarPanel::extensions()`, registered in `CorePlugin`) to append the resolved type's meta form fields to the stock "Values" tab — no fork of Lunar's classes needed. Ships a reference implementation, `Modules\Core\Product\OptionTypes\ColorOptionType`, registered automatically by the new `Modules\Core\Providers\ProductServiceProvider`. Documented in `docs/product-options.md`.
+- `Modules\Core\Product\Services\ProductIndexer::mapVariant()` now includes each option's `handle` (alongside its translated name) in a variant's indexed `options[]` — previously only the translated `option`/`value` names and `meta` were indexed, with no stable, locale-independent identifier for which option a value belongs to.
+- `Modules\Core\Product\Observers\ProductOptionReindexObserver`, wired in the new `Modules\Core\Providers\ProductServiceProvider`, keeps Meilisearch in sync when a `ProductOption` or `ProductOptionValue` is saved or deleted — e.g. picking an Option Type or editing a color's hex. `ProductIndexer::mapVariant()` embeds each option value's `meta` directly into a product's indexed document, but saving the option/value never fires the *product's* own save events, so without this a changed hex would only reach the index on that product's next unrelated reindex. The observer resolves every `Lunar\Models\Product` whose variants use the changed option (or option value) via the `product_option_value_product_variant` pivot, and calls `->searchable()` on each.
+
+### Changed
+- **Breaking:** `Modules\Core\Product\Services\ProductIndexer`'s indexed `collections` field is now an array of `{id, name}` objects instead of two parallel arrays (`collections` as bare ID strings, `collection_names` as translated names joined only by array index). `collection_names` is removed. Filtering by collection now targets the nested field `collections.id` (Meilisearch supports filtering on nested object fields), not bare `collections` — `Modules\Core\Product\Services\ProductService::buildFilter()` updated accordingly; `ProductFilters(collectionId: ...)`'s public API is unchanged. Run `php artisan lunar:meilisearch:setup` then `lunar:search:index --refresh` after upgrading (see docs/product-listing.md "Gotchas").
+- **Breaking:** `ProductIndexer`'s indexed `review_count`/`average_rating` top-level keys are folded into the existing `reviews` key: `reviews` is now `{items, count, average_rating}` instead of a bare array with `review_count`/`average_rating` as separate sibling keys. `reviews` (the array of review items) moved to `reviews.items`.
+
+## [0.6.0] - 2026-08-27
+
+### Added
+- `Modules\Core\Localization\Models\LanguageLine` extends `spatie/laravel-translation-loader`'s `LanguageLine` to fall back to the store's actual default language (`LanguageCache::defaultLocale()`, backed by Lunar's `languages.default` flag) instead of the package's stock behavior of falling back to the static `config('app.fallback_locale')` — the two were previously disconnected, so changing the default language via the Filament **Languages** resource had no effect on which locale an untranslated storefront label silently fell back to. Swapped in automatically via `config('translation-loader.model')` in `LocalizationServiceProvider::register()`; no consuming app changes needed. Documented in `docs/localization.md` ("Fallback locale follows the store's default language").
+
+### Changed
+- **Breaking:** `Modules\Core\Catalog\ProductService::list()` now returns a real `Illuminate\Pagination\LengthAwarePaginator` (built from the localized Meilisearch hits) instead of a plain `array{data, meta}` — gives callers normal Laravel pagination behaviour (`$products->links()`, standard JSON serialization) without ever touching Scout's raw `paginateRaw()` response directly. `getById()`/`getBySlug()` are unaffected (still return `?array`).
+- `ProductService::withLocalizedFields()` (used by `list()`, `getById()`, `getBySlug()`) no longer hardcodes `name`/`description` as the only translated fields — it now reads every `TranslatedText` attribute on `Product` from `Lunar\Base\AttributeManifest` (the same source Lunar's own indexer reads), so a store's own custom translated attributes (e.g. `seo_title`, `seo_description`) are resolved and locale-stripped automatically with no code change here. Raw `{handle}_{locale}` keys (e.g. `name_el`, `seo_title_en`) are now stripped from every returned product, not just `name_*`/`description_*`.
+- Extracted `Modules\Core\Localization\Services\LanguageCache` (cached read layer over Lunar's `languages` table: `all()`, `defaultLocale()`, `availableLocales()`, `forget()`) out of `LocaleMiddleware`, which previously owned this as private/static methods despite not being middleware-specific behavior. `LocaleMiddleware` now takes `LanguageCache` via constructor injection. `LocaleMiddleware::defaultLocale()`/`forgetLanguagesCache()` (static) are removed — use `app(LanguageCache::class)` or inject `LanguageCache` directly.
+
+### Fixed
+- `Modules\Core\MigrateImport\JudgeMe\Resolvers\ProductResolver::resolve()` picked whichever `lunar_urls` row matched a slug first, which can be a soft-deleted product left behind by an earlier import batch rather than the current live one — a store can easily end up with more than one `Product` row sharing the same slug across re-imports, since a soft-deleted product's URL row isn't cleaned up. This silently broke every downstream lookup for that handle (e.g. `Modules\Core\MigrateImport\JudgeMe\JudgeMeExportImporter` logging "no product found for handle, skipping review" and dropping the row, even though a live product with that exact handle existed). Rewrote as a join against `lunar_products` — via `Product::query()`, so Eloquent's `SoftDeletes` global scope excludes trashed rows — so only a URL pointing at a live product resolves.
+- `Modules\Core\Review\Models\ProductReview` had no `registerMediaConversions()` at all, unlike `Product`/`ProductVariant` which get one automatically from Lunar's own `Lunar\Base\StandardMediaDefinitions`. `Modules\Core\Search\ProductIndexer::mapMedia()` is shared across product, variant, and review media and always requests the `small` conversion — the first time a review had an attached image, indexing it threw `Spatie\MediaLibrary\MediaCollections\Exceptions\InvalidConversion`, silently failing the product's `MakeSearchable` queue job (and everything queued after it, since Scout batches). Added a matching `small` conversion (300×300, same fit/border/background as Lunar's standard one) directly on `ProductReview`.
+
+### Breaking
+- Merged `Modules\Core\Catalog` and `Modules\Core\Search` into a single `Modules\Core\Product` concern, since both existed purely to serve `Product` (browsing/filtering vs. indexing/full-text search — two services, one concern), following a stricter subfolder convention (`Contracts/`, `Enums/`, `Services/`, `DTOs/`, `Models/`, etc. per concern) going forward:
+  - `Modules\Core\Catalog\ProductService` → `Modules\Core\Product\Services\ProductService`
+  - `Modules\Core\Catalog\ProductFilters` → `Modules\Core\Product\DTOs\ProductFilters`
+  - `Modules\Core\Catalog\ProductSort` → `Modules\Core\Product\Enums\ProductSort`
+  - `Modules\Core\Search\ProductIndexer` → `Modules\Core\Product\Services\ProductIndexer`
+  - `Modules\Core\Search\ProductSearchService` → `Modules\Core\Product\Services\ProductSearchService`
+
+  Consuming apps must update any direct references — notably `config/lunar/search.php`'s `'indexers'` map, which points at `ProductIndexer` by FQCN. `Modules\Core\Catalog\ProductOptionTypeInterface` (in-progress, not yet wired to anything) was deliberately left in place rather than moved.
+- Reorganized `Modules\Core\Localization` under the same stricter per-concern subfolder convention — `Events/`, `Filament/`, `Listeners/` were already correctly categorized; four loose root files moved into typed buckets by structural role:
+  - `Modules\Core\Localization\LocaleMiddleware` → `Modules\Core\Localization\Middleware\LocaleMiddleware`
+  - `Modules\Core\Localization\LanguageCacheObserver` → `Modules\Core\Localization\Observers\LanguageCacheObserver`
+  - `Modules\Core\Localization\TranslationReader` → `Modules\Core\Localization\Services\TranslationReader`
+  - `Modules\Core\Localization\TranslationService` → `Modules\Core\Localization\Services\TranslationService`
+
+  `Modules\Core\Localization\Services\LanguageCache` (added earlier in this same unreleased version) already lived at its correct final path — unaffected. The `'locale'` route-middleware alias (registered in `LocalizationServiceProvider`) is unaffected for consuming apps using it by string alias rather than FQCN.
+
+## [0.5.4] - 2026-08-26
+
+### Added
+- `Modules\Core\Catalog\ProductService::list()` accepts a `sort` parameter (new `ProductSort` enum: `PriceAsc`, `PriceDesc`, `Newest`), translated into a Meilisearch `sort` clause — `list()` previously had no way to order results, since it always searches with an empty query string and so has no relevance score to fall back on. `Modules\Core\Search\ProductIndexer::getSortableFields()` now also marks `price` sortable (Lunar's base indexer only marks `created_at`/`updated_at`/`skus`/`status`). Requires re-syncing index settings (`php artisan lunar:meilisearch:setup`) on existing stores. Documented in `docs/product-listing.md` ("Sorting").
+
+## [0.5.3] - 2026-08-26
+
+### Fixed
+- `Modules\Core\Search\ProductIndexer::toSearchableArray()` threw `column reference "id" is ambiguous` on Postgres when computing `channel_ids` — `$model->channels()->wherePivot('enabled', true)->pluck('id')` joins `lunar_channels` and `lunar_channelables`, both of which have an `id` column, and the unqualified `pluck('id')` left Postgres unable to resolve which table's column to select (SQLite/MySQL tolerated the ambiguity). Qualified as `pluck('lunar_channels.id')`.
+
+## [0.5.2] - 2026-08-26
+
+### Fixed
+- `Modules\Core\Localization\LocaleMiddleware`'s shared view data only ever surfaced a single alternate locale (`altLocale`/`altLocaleUrl`, found via `firstWhere('code', '!=', $current)`) — correct by coincidence for a 2-language store, but silently dropped every locale past the first "other" one found for a 3+ language store, with no error. Replaced with `altLocales`, a collection of every other configured language (`code`, `name`, `url` for the current route each), so a language switcher or `hreflang` tags scale to any number of locales. Documented in `docs/localization.md` ("Shared view data — language switcher and `hreflang` tags").
+
+## [0.5.1] - 2026-08-25
+
+### Added
+- `Modules\Core\Search\ProductIndexer` now indexes `channel_ids` (filterable) — Lunar's base indexer only marks `status` as filterable, not channel assignment, so storefront search couldn't otherwise scope results to products actually assigned and enabled on the current sales channel. Computed from `$product->channels()->wherePivot('enabled', true)`. Ported from an older `Products` branch whose remote had been deleted; the branch's other, now-superseded `ProductIndexer` changes were dropped in favor of the richer indexer already on `master` (collections, price, variants, reviews — see `0.5.0`).
+
+## [0.5.0] - 2026-08-24
+
+### Added
+- **`Modules\Core\Catalog\ProductService`**: storefront product listing/filtering (`list()`) and single-product lookup (`getById()`, `getBySlug()`), reading directly from the Meilisearch index rather than the database — one data source, no `->get()` model hydration. Returns plain arrays (not Eloquent models), meant to be called directly from a consuming app's controllers.
+  - `ProductFilters` DTO: optional `collectionId`, `brand`, `minPrice`, `maxPrice`, translated into a Meilisearch `filter` expression.
+  - Listing results are locale-aware: `withLocalizedFields()` resolves `name`/`description` from the indexer's per-locale fields, falling back to the store's default language (via `LocaleMiddleware::defaultLocale()`) when the current locale has no translation yet, instead of rendering blank.
+  - `Modules\Core\Search\ProductIndexer` expanded well beyond its original collection/price additions to carry everything a detail page needs: `id`/`slugs` (filterable — `getById()`/`getBySlug()` resolve purely from the index, no database read), `collection_names`, `tags`, the full media gallery, per-variant data (`sku`, `stock`, `purchasable`, translated option/value names + `meta` for swatches, per-currency prices, variant media), and reviews (`reviews`, `review_count`, `average_rating` — public-safe fields only, `reviewer_email` deliberately excluded).
+  - `Modules\Core\Providers\ReviewServiceProvider` (newly registered): re-indexes a product whenever one of its reviews is created/updated/deleted, since a review write doesn't touch the `Product` row and so never fires the product's own model events.
+- **`Modules\Core\Search\ProductSearchService`**: locale-aware full-text product search on top of the same Meilisearch index, for use by a storefront's search bar — separate from `ProductService`, which is for browsing/filtering without a query term.
+- `docs/product-listing.md` and `docs/product-search.md` — usage, full field reference, and design notes for the two services above.
+- `docs/lunar.md` "Gotchas": three new entries hit while building this — `ProductOption`/`ProductOptionValue::name` isn't `attribute_data` (so `translateAttribute()` silently returns `null` for it), a running `queue:work` process not picking up an edited Scout indexer class, and Scout's `paginateRaw()->items()` on the Meilisearch driver returning the whole raw response rather than a hit list.
+
+### Fixed
+- The admin login form (`Modules\Core\Auth\Filament\Pages\Login`) had no way back from the OTP-entry step to the email step short of reloading the page. A `back()` method resets to the email step; a "← Back" link/button is shown on the OTP step only.
+
+## [0.4.0] - 2026-08-06
+
+### Added
+- **Locale-prefixed routing** (`Modules\Core\Localization\LocaleMiddleware`): a `locale` route-middleware alias, opt-in per shop (not pushed onto the `web` group globally, since admin/Livewire/webhook routes must not be locale-redirected). Reads the first URL segment against Lunar's own `languages` table, sets `App::setLocale()`, and redirects unprefixed/unknown-locale requests to a resolved locale (`Accept-Language` match → default language → first language). Every locale is prefixed, including the default (`/el/...`, `/en/...`), never a bare root — avoids the hreflang/duplicate-content ambiguity of a bare-root default locale.
+  - Language list cached with `Cache::rememberForever()`, invalidated via `Modules\Core\Localization\LanguageCacheObserver` dispatching `LanguageCreated`/`LanguageUpdated`/`LanguageDeleted` events (see below) rather than doing the work itself.
+  - **Language rename safety**: renaming a `Language::code` (e.g. `el` → `gr`) no longer strands existing translations. `MigrateTranslationsForRenamedLanguage` (listening on `LanguageUpdated`) migrates every affected `LanguageLine.text` key from the old code to the new one and flushes both codes' translation caches — closing a real data-loss gap where a rename would otherwise make existing `LanguageLine` translations permanently unreachable.
+- **Storefront UI label translations**: pulled in `spatie/laravel-translation-loader` (self-registers via Composer package auto-discovery; its loader *extends* Laravel's file-based `FileLoader` and merges DB translations on top — existing Filament/Lunar vendor `lang/` strings are unaffected). Labels are looked up via Laravel's native `__('storefront.nav.cart')`, kept in its own `storefront` group so nothing collides with Lunar/Filament's own translation groups.
+  - `Modules\Core\Command\InstallLunarCommand` (overriding `lunar:install`) seeds a starter set of ~15 common e-shop labels (`nav.*`, `cart.*`, `product.*`, `auth.*`, `search.*`, English + Greek), idempotently guarded so it's safe on every boot.
+  - `Modules\Core\Localization\TranslationReader::group('storefront')` returns the whole reduced/cached label array for a locale (backed by `LanguageLine`'s own forever-cache) — for sharing to a view as `$labels` or `@json()`-ing to JS, on top of `__()` for single-key Blade lookups.
+  - **Admin UI**: `Modules\Core\Localization\Filament\Resources\LanguageLineResource` (registered in `CorePlugin`) lists/searches/filters `language_lines` and edits each row's `group`, `key`, and one text input per locale currently in `lunar_languages` — locale columns/inputs are generated dynamically from the language list, so a new language needs no resource changes.
+  - **Event-driven writes**: `Modules\Core\Localization\TranslationService` (`create`/`update`/`delete`) is the single write path for `LanguageLine` — the Filament resource's Create/Edit/Delete pages route through it rather than Filament's default direct-model writes. Dispatches `TranslationCreated`/`TranslationUpdated` (carries the full pre-update `{group, key, text}` snapshot, so a bare rename is tracked the same as a text edit)/`TranslationDeleted`, each handled by two listeners:
+    - `FlushTranslationCache` — closes a real gap in `LanguageLine`'s own self-invalidation, which only flushes locales/groups present *after* a save. Flushes the union of old and new group+locale combinations, so a locale removed from `text`, or a `group`/`key` rename, can't leave a stale cached array behind.
+    - `LogTranslationActivity` — audits every write via the existing `Modules\Core\Logging\ActivityLogService` (`lunar` activity log channel), same `created`/`updated`/`deleted` shape as every other domain write in this project. Properties are flattened with `Arr::dot()` before logging (`text.en`, `text.el` instead of a nested `text` object) since Filament's Activity resource renders `properties` with a flat `KeyValue` field that can't display nested arrays.
+- `Modules\Core\Providers\LocalizationServiceProvider` — split out of the growing `CoreServiceProvider` (per this project's own "split when a provider does too much" convention) to own all locale/translation middleware, observer, and event-listener registration.
+
+## [0.3.0] - 2026-07-12
+
+### Added
+- **Meilisearch product search**: pulled in `lunarphp/search` (Lunar's driver-agnostic search abstraction — `database`/`meilisearch`/`typesense` engines, selectable via Scout's own `SCOUT_DRIVER` config) and `lunarphp/meilisearch`, wiring Meilisearch in as the search engine for products.
+  - `Search\ProductIndexer` overrides Lunar's own indexer to strip HTML tags from string fields (e.g. `name_en`, `description_en`) before they reach the search index — Lunar's default indexer sends raw attribute HTML straight through, which pollutes relevance ranking and highlighting with markup.
+  - Meilisearch itself is treated as app-level infrastructure, not a `boboko-core` concern: the actual Meilisearch container, host port, and master key live in each consuming app's own `docker-compose.yml`/`.env` (e.g. `3dealer`), the same way Postgres and Valkey do — `boboko-core` only declares the PHP package dependency and the indexing code.

+# Cart Admin Visibility
+
+`Modules\Core\Cart\Filament\Resources\CartResource` gives staff read-only visibility into
+customer/user carts in the Filament admin panel. Lunar itself ships no cart admin view at
+all — no Filament resource for `Cart`/`CartLine` exists anywhere in `lunarphp/lunar` or
+`lunarphp/core` — this is a from-scratch addition, not an extension of something Lunar
+half-built. See `docs/lunar.md`'s "Cart and Checkout" section for the underlying Lunar cart
+mechanics this resource reads from.
+
+---
+
+## Scope: only carts with a known customer or user
+
+`CartResource::getEloquentQuery()` filters to `Cart::whereNotNull('user_id')->orWhereNotNull('customer_id')`
+— an anonymous guest's session cart is excluded entirely.
+
+This was a deliberate call, not an oversight: an anonymous cart carries no identity a staff
+member could act on — no name, no email, nothing to follow up with — so listing every guest
+session cart would be noise, not a real admin capability. This does **not** mirror Shopify's
+admin (Shopify has no "all carts" view at all — only "Abandoned checkouts," gated on a
+shopper reaching checkout and entering contact info, a later/narrower stage than Lunar's
+`Cart`). Lunar's own `Cart` model already gets `user_id`/`customer_id` set the moment a
+shopper is authenticated (via `Lunar\Listeners\CartSessionAuthListener` on login), with no
+checkout step required — so scoping to "identifiable" here is broader than Shopify's
+equivalent, not a copy of it.
+
+---
+
+## Four states, not two — and not `Cart::completed_at`
+
+`Lunar\Models\Cart::completed_at` is declared and cast (`'completed_at' => 'datetime'`) but
+**never actually written anywhere in Lunar core** — grep `vendor/lunarphp/core/src` for it;
+the only hits are the property declaration and the cast. It is not a real signal. `Cart` has
+no `status` column at all — every state below is derived from relations/timestamps, not a
+single field.
+
+`Cart::scopeActive()` (Lunar's own "not yet converted to an order" scope) actually mixes two
+distinct states together: no order ever started, vs. a draft order exists
+(`placed_at IS NULL`) but was never placed — checkout was started, not finished. Those are
+different purchase-intent signals (see "Abandoned Cart vs Abandoned Checkout" below) and
+different reachability (checkout usually captures an email even for a guest), so
+`ListCarts::getTabs()` splits them into four tabs instead of `scopeActive()`'s two-state
+split:
+
+- **Ongoing** — `scopeActive()` and recent `updated_at` (within `abandonedCutoff()`). Default
+  active tab on page load.
+- **Abandoned Cart** — `whereDoesntHave('orders')` and stale `updated_at`.
+- **Abandoned Checkout** — has an order with `placed_at IS NULL`, and stale `updated_at`.
+- **Completed** — has an order with `placed_at IS NOT NULL`.
+
+```php
+// Ongoing
+$query->active()->where('updated_at', '>', CartResource::abandonedCutoff());
+
+// Abandoned Cart
+$query->whereDoesntHave('orders')->where('updated_at', '<=', CartResource::abandonedCutoff());
+
+// Abandoned Checkout
+$query->whereHas('orders', fn ($q) => $q->whereNull('placed_at'))
+    ->where('updated_at', '<=', CartResource::abandonedCutoff());
+
+// Completed
+$query->whereHas('orders', fn ($q) => $q->whereNotNull('placed_at'));
+```
+
+There is deliberately **no "All" tab.** Every row shown is always scoped to one of the four
+states above — the list never runs an unfiltered `Cart::query()->get()` over the whole
+(potentially large) table.
+
+### Abandoned Cart vs Abandoned Checkout — why they're not one bucket
+
+Different purchase intent, different reachability, and different recovery strategy — see
+`docs/recovery-strategies.md` for the full marketing-strategy discussion. In short:
+
+- **Abandoned Cart** (no order started) is a weak intent signal — often window-shopping, not
+  a near-purchase. Frequently unreachable (no email/identity at all for a true guest).
+  Recovery leans on on-site retargeting and ad remarketing rather than email.
+- **Abandoned Checkout** (draft order, never placed) is a strong intent signal — the shopper
+  committed to buying and something blocked completion. Checkout typically captures contact
+  info even for a guest, so this state is usually reachable. This is the state the
+  researched 1h/24h/72h recovery-email cadence targets specifically.
+
+`Modules\Core\Cart\Events\CartAbandoned` and `Modules\Core\Checkout\Events\CheckoutAbandoned`
+mirror this same split (see "Events" below) rather than one combined event.
+
+---
+
+## Why this scales fine at a large cart count
+
+Two things keep this cheap regardless of how many carts exist (10,000+):
+
+- **The list is always paginated.** Filament applies `LIMIT`/`OFFSET` to whichever tab's
+  query is active — a page only ever fetches one page's worth of rows, never the whole
+  table, "All" tab or not (and there is no "All" tab — see above).
+- **No per-row queries.** `lines_count`/`lines_sum_quantity` use Filament's built-in
+  `->counts('lines')`/`->sum('lines', 'quantity')`, which fold into the same query as the
+  rest of the list (one `LEFT JOIN`-based aggregate, not N separate lookups). There's no
+  per-record `getStateUsing()` closure anywhere in this table doing its own query — that's
+  the pattern to avoid if a future column needs derived data (see `Modules\Core\Catalog\
+  Services\ProductIndexer` for the general "compute once at index time / one aggregate
+  query, never per-row" principle this project follows elsewhere).
+
+The one thing that **does** scan more rows as the cart count grows is
+`CartResource::getNavigationBadge()` (see below) — but it's a `COUNT(*)`, not a fetch, and
+runs once per admin page load, not once per cart row.
+
+---
+
+## Navigation badge — abandoned cart count
+
+```php
+public static function getNavigationBadge(): ?string
+{
+    return (string) static::getEloquentQuery()->active()->count();
+}
+```
+
+Shows the number of abandoned carts (not all carts — a converted cart isn't something a
+staff member needs to keep noticing) next to "Carts" in the sidebar. `->count()` compiles to
+a single `SELECT COUNT(*) ...` — confirmed via query log — no rows are ever loaded just to
+render the badge.
+
+---
+
+## The view page runs the cart's full calculate pipeline — once
+
+`ViewCart::resolveRecord()` calls `$cart->calculate()` before rendering, since `CartLine`'s
+computed properties (`unitPrice`, `total`, etc.) and `Cart`'s own totals (`subTotal`, `total`,
+...) are plain public properties populated as a side effect of that pipeline — never
+persisted, so a plain Eloquent-fetched `Cart` has them all `null`/unset (see `docs/lunar.md`
+Gotchas). This only runs on the single-record view page, not per row in the list table —
+running the full 5-step pipeline for every row of a paginated list would be needless cost for
+data the list doesn't display.
+
+---
+
+## Not built: staff editing a cart
+
+The resource is deliberately read-only (`canCreate()` returns `false`, no edit page
+registered). A cart is owned by the storefront's own add/update/remove flow
+(`CartSession`/`Cart::add()`/etc.) — hand-editing cart contents from the admin panel isn't a
+supported use case here.
+
+---
+
+## `CartService` — the storefront-facing API
+
+`Modules\Core\Cart\Services\CartService` mirrors `Modules\Core\Catalog\Services\
+ProductService`/`CollectionService`'s shape — one boboko-owned API a storefront calls, so
+Lunar's own `CartSession`/`Cart` stay an implementation detail rather than something a
+consuming app depends on directly.
+
+- `current()` / `currentOrCreate()` — the latter force-creates a cart (`CartSession::manager()`),
+  the former doesn't (`CartSession::current()`, returns `null` for a fresh visitor — see
+  `docs/lunar.md`'s Cart gotchas).
+- `addLine()` / `updateLine()` / `removeLine()` / `clear()` — thin wrappers over
+  `Cart::add()`/`updateLine()`/`remove()`/`clear()`. No boboko-owned exception types wrap
+  Lunar's own cart exceptions (`InvalidCartLineQuantityException`, `CartLineIdMismatchException`,
+  etc.) — they propagate as-is; a wrapper would add indirection with identical semantics.
+- `applyCoupon()` / `removeCoupon()` — sets/clears `Cart::coupon_code` (there's no dedicated
+  Lunar action for this, unlike add/update/remove). `applyCoupon()` validates via
+  `Discounts::validateCoupon()` first and throws `Modules\Core\Cart\Exceptions\
+  InvalidCouponException` on a bad code — `CouponString`'s cast only normalizes casing, it
+  doesn't validate anything, so setting `coupon_code` directly would silently accept a bogus
+  code and just not discount anything once calculated.
+- `saveForLater()` / `moveToCart()` / `activeLines()` / `savedLines()` — see "Save for later"
+  below.
+
+Every mutating method returns the recalculated `Cart` (matching Lunar's own `Cart::add()`
+etc., which already return `$this` after `refresh()->recalculate()`) and dispatches a
+matching domain event.
+
+### Events — Lunar dispatches none of its own
+
+`Lunar` dispatches zero cart events — no "item added," no "cart created" (see
+`docs/lunar.md`'s Cart gotchas). `CartService` fills that gap with its own, dispatched after
+the underlying Lunar operation completes:
+
+`CartLineAdded`, `CartLineUpdated`, `CartLineRemoved`, `CartCleared`, `CartCouponApplied`,
+`CartCouponRemoved`, `CartLineSaved`, `CartLineMovedToCart` — all under
+`Modules\Core\Cart\Events`. `CartAbandoned`/`CheckoutAbandoned` live under
+`Modules\Core\Recovery\Events` instead, not `Cart`/`Checkout` — see "Abandonment detection"
+below for why.
+
+**None of these currently have a listener.** They're dispatched-but-unconsumed by design —
+built so something downstream (reindexing, notifications, a future read-side reporting
+service) has a hook to attach to, not because a concrete consumer exists today. This was a
+deliberate decision, not an oversight — see the "don't build speculative infrastructure"
+calls made elsewhere in this project (e.g. not wrapping Lunar's cart exceptions).
+
+**Why not wired to Spatie's Activity Log:** `Cart`/`CartLine` already use Lunar's own
+`LogsActivity` trait (Spatie's package, Lunar's defaults) — confirmed from source, this logs
+model saves/deletes automatically, independent of actor. `Modules\Core\Logging\
+ActivityLogService` (this project's own wrapper, used by e.g. `LogTranslationActivity`) is
+hardcoded to the `staff` guard — correctly scoped for staff-driven writes (Filament admin
+actions), but wrong for customer-driven cart activity, which would resolve `causedBy()` to
+`null` every time. Both `ActivityLogService` and `Cart`/`CartLine`'s native `LogsActivity`
+write to the **same** `log_name = 'lunar'` / `activity_log` table, with no built-in
+separation beyond reading `causer_type` per row — a real limitation worth knowing about, but
+not one this project is fixing by giving Cart a distinct `log_name`, since every other Lunar
+model logs to `'lunar'` too and a Cart-only carve-out would just be inconsistent. The
+intended fix, if this becomes a real need, is a read-side service that queries `activity_log`
+and classifies by `causer_type`/`log_name` — not touching every write site.
+
+### Save for later
+
+A `CartLine` can be moved out of the purchasable cart without being deleted — flagged via
+`meta.saved_for_later`, not a new column (matches the free-form-JSON pattern already used
+elsewhere, e.g. `ProductOptionValue::meta`). `Modules\Core\Cart\Pipelines\
+ZeroSavedForLaterPrice` (registered in `config('lunar.cart.pipelines.cart_lines')`, after the
+stock `GetUnitPrice`) zeroes `unitPrice`/`unitPriceInclTax` for flagged lines **before**
+Lunar's own `CalculateLines` pipeline step sums the cart — `CalculateLines` sums every
+`CartLine` unconditionally with no meta-based exclusion of its own, so zeroing the price
+upstream is what makes `Cart::subTotal`/`total` naturally correct without a second pass or
+callers needing a different totals accessor.
+
+`Lunar\Actions\Carts\UpdateCartLine` **replaces** the whole `meta` column on write (plain
+`update(['meta' => $meta])`, not a merge) — `saveForLater()`/`moveToCart()` read the line's
+existing meta and merge in the flag change before calling `Cart::updateLine()`, or an
+unrelated meta key set by something else would be silently wiped.
+
+### Coupons
+
+See `CartService::applyCoupon()`/`removeCoupon()` above. `Lunar\Base\Casts\CouponString`
+just upper-cases the code; `Lunar\Managers\DiscountManager::validateCoupon()` (via the
+`Discounts` facade) is the actual check — does a matching `Discount` (type `AmountOff` or
+`BuyXGetY`) exist, `active()`, with `max_uses` not exhausted.
+
+---
+
+## Abandonment detection
+
+"Abandoned" is a **derived** state (`Cart::updated_at` older than
+`config('core.cart.abandoned_after')`, default `1 hour`) — nothing transitions a cart into it
+via a normal Eloquent write, so there's no model-event hook to dispatch from directly.
+`Modules\Core\Cart\Commands\DetectAbandonedCarts` (registered on an hourly schedule by
+`Modules\Core\Providers\CartServiceProvider`) is the only place that moment gets detected: it
+queries the same two branches `ListCarts::getTabs()` uses (no order at all vs. draft order
+never placed) and dispatches `Modules\Core\Recovery\Events\CartAbandoned`/`CheckoutAbandoned`
+for anything currently stale.
+
+### Cart/Checkout have zero abandonment-related writes — by design
+
+`DetectAbandonedCarts` **only dispatches** — it never writes to `Cart`/`Order` at all. An
+earlier version recorded an "already notified" marker on `Cart::meta`/`Order::meta` to avoid
+refiring the same event every run, but that `->save()` call bumped `Cart::updated_at` as an
+Eloquent side effect — since `updated_at` is also the field abandonment staleness is computed
+from, the write **un-staled the very cart it had just marked abandoned**: confirmed live, a
+cart that correctly fired `CartAbandoned` showed back up as "Ongoing," not "Abandoned Cart,"
+on the very next tab-count check.
+
+The fix wasn't to write the marker more carefully — it was to stop `Cart`/`Checkout` from
+having any way to write abandonment state at all. Deduplication ("has this cart already been
+notified") is deliberately **not** this command's job; it belongs to `Recovery` (not yet
+built — see `docs/recovery-strategies.md`), which will own its own tracking table, keeping
+`Cart`/`Order` permanently free of abandonment-related columns or `meta` keys.
+
+**Current tradeoff, accepted deliberately**: until `Recovery` exists, every cart still
+matching the "abandoned" query refires its event on every hourly run — there is no dedup at
+all right now. That's fine today only because nothing consumes these events yet (see
+"Events" above); it would need addressing before anything real listens for them.

+# Collections
+
+`Modules\Core\Catalog\Services\CollectionService` provides category browsing/nav AND
+single-collection lookup for a storefront — `list()`, `getById()`, `getBySlug()` —
+all reading directly from the Meilisearch index, mirroring
+`Modules\Core\Catalog\Services\ProductService` (see `product-listing.md`) exactly.
+
+---
+
+## Why it reads from the index, not the database
+
+Lunar's own `Lunar\Search\CollectionIndexer` only carries `id`/`name`/`created_at` —
+nowhere near enough for a storefront category page or a nav tree.
+`Modules\Core\Catalog\Services\CollectionIndexer` extends it to add everything
+`CollectionService` needs:
+
+| Field | Source | Notes |
+|---|---|---|
+| `parent_id` | `$model->parent_id` | Filterable. The nested-set tree's parent pointer — `null` for a top-level collection. |
+| `_lft` | `$model->_lft` | Filterable and sortable. The nested-set tree position — lets `CollectionService` resolve tree order without a database read. |
+| `collection_group_id` | `$model->collection_group_id` | Filterable. Mirrors `Collection::scopeInGroup()`. |
+| `slugs` | `$model->urls->pluck('slug')` | Filterable. Every locale's `Url::slug`, so `getBySlug()` resolves purely from the index. |
+| `thumbnail` | `$model->getThumbnailImage()` | Display only. `null` if the collection has no thumbnail image. |
+| `ancestors` | `$model->ancestors` | Display only. Array of `{id, name}`, ordered root-first — a breadcrumb (`Home > Apparel > Keychains`) can render directly from a single `getById()`/`getBySlug()` call, no extra queries. Empty array for a top-level collection. |
+| `product_count` | Queried from the *product* Meilisearch index at collection-index time | Display only. How many products are in this collection **or any of its descendants** — matches what `ProductService::list(ProductFilters(collectionId: ...))` would return, not just direct assignment. Computed via `Product::search('')->options(['filter' => "collection_ids = \"{id}\""])`, so it depends on the product index already being current — reindex products *before* collections (see "Gotchas" below). |
+
+`name`/`description` (and any other `TranslatedText` attribute) are indexed per-locale
+by Lunar's base indexer and resolved by `CollectionService` exactly like
+`ProductService` does — see `product-listing.md`'s "Locale resolution" section, same
+logic, same `LanguageCache::defaultLocale()` fallback.
+
+---
+
+## Usage
+
+```php
+use Modules\Core\Catalog\DTOs\CollectionFilters;
+use Modules\Core\Catalog\Enums\CollectionSort;
+use Modules\Core\Catalog\Services\CollectionService;
+
+$service = app(CollectionService::class);
+
+// Top-level collections only (parent_id IS NULL) — for building a nav tree
+$roots = $service->list(
+    filters: new CollectionFilters(rootOnly: true),
+    sort: CollectionSort::Position,
+);
+
+// Children of a specific collection
+$children = $service->list(
+    filters: new CollectionFilters(parentId: 222),
+    sort: CollectionSort::Position,
+);
+
+// Filter by collection group
+$collections = $service->list(filters: new CollectionFilters(groupId: 4));
+
+// Single collection, by primary key or slug
+$collection = $service->getById(223);
+$collection = $service->getBySlug('keychains');
+```
+
+`CollectionFilters(parentId: ..., rootOnly: ...)` are mutually exclusive — if both are
+set, `parentId` wins. There's no `parentId: null` shorthand for "root only", since
+that would be ambiguous with "don't filter by parent at all" (the DTO's actual
+default); `rootOnly` names the root-collections case explicitly instead.
+
+`CollectionSort::Position` (`_lft:asc`) is the recommended default for any nav/tree
+UI — it matches the order an admin arranges collections in Lunar's own Filament UI.
+`Name` and `Newest` are also available, mirroring `ProductSort`'s shape.
+
+---
+
+## Registration
+
+Like `ProductIndexer`, `CollectionIndexer` must be registered in the consuming app's
+own `config/lunar/search.php`:
+
+```php
+'indexers' => [
+    Lunar\Models\Collection::class => Modules\Core\Catalog\Services\CollectionIndexer::class,
+    // ...
+],
+```
+
+New/changed fields aren't filterable/sortable in Meilisearch until `php artisan
+lunar:meilisearch:setup` re-syncs index settings, and existing documents need
+`lunar:search:index --refresh` to pick up the new shape. If `SCOUT_QUEUE` is enabled,
+the queue worker also needs restarting after deploying changes to the indexer class —
+see `docs/lunar.md` "Gotchas".
+
+**`product_count` needs the product index reindexed first.** `config/lunar/search.php`'s
+`indexers` array is typically ordered `Collection` before `Product`, so a plain
+`lunar:search:index --refresh` computes `product_count` against whatever the product
+index held *before* this run — stale if products changed too. `lunar:search:index`
+takes an explicit model list as its argument (`--ignore` restricts it to only those),
+so reindex products first, then collections, when both need a fresh `--refresh` in the
+same deploy:
+
+```
+php artisan lunar:search:index "Lunar\Models\Product" --ignore --refresh
+php artisan lunar:search:index "Lunar\Models\Collection" --ignore --refresh
+```
+
+---
+
+## When to still use Eloquent directly
+
+A single collection's full detail page (breadcrumb via `$collection->breadcrumb`,
+tree ancestors/descendants, route-model-bound `Collection $collection` in a
+controller signature) should keep reading Eloquent directly rather than going through
+`CollectionService` — the indexed document doesn't carry ancestor chains or the full
+nested-set relations, and route-model binding already gives a controller the full
+model for free. `CollectionService` is for browsing/listing and lightweight
+by-id/by-slug lookups where a full Eloquent hydration would be wasteful, the same
+tradeoff `ProductService` makes for products.

+# Localization
+
+Storefront routes can be locale-prefixed (`/el/proionta`, `/en/products`) using a middleware
+that reads directly from Lunar's `languages` table — the same table the Filament **Languages**
+resource manages, so there's no separate locale config to keep in sync.
+
+---
+
+## Why prefix every locale, including the default
+
+Leaving the default locale bare at the root (`/proionta` for Greek, `/en/products` for English)
+creates ambiguity: is `/` the language-neutral homepage or specifically the Greek version? It
+also complicates `hreflang` (needs a self-referencing tag on the root plus a possibly-duplicate
+`x-default`) and risks duplicate content if a bot or campaign link reaches the root without a
+language signal.
+
+Prefixing every locale avoids this: every URL unambiguously declares its language, `hreflang`
+tags are symmetrical, and adding a locale later requires no URL restructuring.
+
+---
+
+## Opt-in, not global
+
+The middleware is registered as a **named alias** (`locale`), not pushed onto the `web`
+middleware group. Apply it explicitly to the route group(s) that make up your storefront:
+
+```php
+// routes/web.php
+use Illuminate\Support\Facades\Route;
+
+Route::middleware('locale')->group(function () {
+    Route::get('/{locale}', HomeController::class);
+    Route::get('/{locale}/proionta', ProductIndexController::class);
+    Route::get('/{locale}/proionta/{slug}', ProductShowController::class);
+});
+```
+
+It is **not** applied automatically because storefront routes aren't the only routes living
+under `web` in a shop:
+
+- The Filament admin panel (`/boboko*`, see `PanelServiceProvider`) has its own routing/auth
+  concerns and must never be locale-redirected.
+- Livewire's internal update endpoint (`/livewire/update`) must resolve without a locale prefix.
+- Webhooks, health checks, and other non-storefront routes shouldn't be touched.
+
+If a shop's entire `web.php` *is* the storefront, wrapping the whole file in the group above is
+fine — just keep admin/Livewire/webhook routes registered outside of it (as they already are).
+
+---
+
+## Behavior
+
+`Modules\Core\Localization\Middleware\LocaleMiddleware`:
+
+1. Reads the first path segment (`request()->segment(1)`).
+2. Matches it against `Lunar\Models\Language::code`.
+   - **Match** — `App::setLocale($code)` is set, and `locale` / `language` request attributes
+     are populated for controllers/views to use.
+   - **No match** (missing, wrong, or unknown segment) — redirects to the same path prefixed
+     with a resolved locale:
+     - the best match from the `Accept-Language` header against available language codes, or
+     - the language flagged `default` in the `languages` table, or
+     - the first language row, as a last resort.
+
+The language list is cached with `Cache::rememberForever()` under `core.localization.languages`
+and invalidated automatically. Adding, editing, or removing a language via the Filament
+**Languages** resource clears the cache immediately — no TTL, no stale reads.
+
+### How invalidation is wired (event-driven, not the observer itself)
+
+`Modules\Core\Localization\Observers\LanguageCacheObserver` observes `Lunar\Models\Language`'s
+`created`/`updated`/`deleted` Eloquent events, but it's a thin trigger only — it doesn't do any
+invalidation work itself. It dispatches one of three events from
+`Modules\Core\Localization\Events` (`LanguageCreated`, `LanguageUpdated` — carrying the old
+`code` — or `LanguageDeleted`), and two listeners, wired in
+`Modules\Core\Providers\LocalizationServiceProvider`, react:
+
+- **`FlushLanguageCache`** — flushes `core.localization.languages` on all three events.
+- **`MigrateTranslationsForRenamedLanguage`** — `LanguageUpdated` only, and only when `code`
+  actually changed. A renamed `Language::code` (e.g. `el` → `gr`) would otherwise strand every
+  `LanguageLine`'s translated text under the old, now-unroutable key —
+  `getTranslationsForGroup('gr', ...)` would silently return nothing for that locale even though
+  the translated content still exists. This listener moves the `text.{oldCode}` key to
+  `text.{newCode}` on every affected `LanguageLine` row and flushes both the old and new code's
+  translation cache for every group touched.
+
+Deleting a `Language` only flushes the language-list cache — `LanguageLine.text` keys for the
+deleted code are left in place rather than destructively erased, in case the language is ever
+re-added under the same code.
+
+Splitting cache-flush and text-migration into separate listeners (rather than one
+`LanguageCacheObserver` method doing both) mirrors the same event → listener pattern used for
+`TranslationService`'s writes below — the observer only detects *what happened*, listeners own
+*what to do about it*.
+
+---
+
+## Reading the resolved locale/language downstream
+
+```php
+// In a controller or view composer
+$locale = $request->attributes->get('locale');      // e.g. "el"
+$language = $request->attributes->get('language');   // Lunar\Models\Language instance
+```
+
+Use `$language->id` when querying Lunar's translatable content (e.g. `Url::where('language_id', ...)`).
+
+### Shared view data — language switcher and `hreflang` tags
+
+The middleware also shares two variables with every view, via `View::share()`, so a layout's
+language switcher or `hreflang` tags don't have to recompute the language list themselves:
+
+```blade
+{{-- current locale --}}
+{{ $currentLocale }}   {{-- e.g. "el" --}}
+
+{{-- every OTHER configured language, each with its own URL for the current page --}}
+@foreach ($altLocales as $altLocale)
+    <a href="{{ $altLocale['url'] }}" hreflang="{{ $altLocale['code'] }}">{{ $altLocale['name'] }}</a>
+@endforeach
+```
+
+`$altLocales` is a **collection**, not a single value — deliberately, so it scales to any number
+of configured languages rather than assuming exactly two. Each entry is a plain array:
+
+| Key | Description |
+|---|---|
+| `code` | The language's `Lunar\Models\Language::code` (e.g. `en`) |
+| `name` | The language's display name |
+| `url` | The **current route**, re-generated with that language's code — via `route($routeName, [...])` when the current request matched a named route, or a bare `/{code}` fallback otherwise |
+
+A 3+ language store gets one `$altLocales` entry per additional language automatically — nothing
+about this shape assumes or special-cases a two-language store.
+
+---
+
+## Single-language shops
+
+If a shop has only one row in `languages`, the middleware still enforces the prefix (e.g. every
+URL under `/en/...`) rather than special-casing it away — this keeps behavior identical across
+shops and avoids a silent restructuring if a second language is added later. If a shop genuinely
+never wants locale prefixes, don't apply the `locale` middleware to its routes at all.
+
+---
+
+## Storefront UI labels (`__('storefront.*')`)
+
+The `locale` middleware resolves *which* language a request is in — routing/redirects,
+`Lunar\Models\Language`, and Lunar's own translatable product/collection content. It has nothing
+to do with static UI chrome like "Cart", "Back", "Add to Cart". Those are handled separately by
+[`spatie/laravel-translation-loader`](https://github.com/spatie/laravel-translation-loader),
+stored in the `language_lines` table.
+
+### Why a separate system, not another `languages`-table lookup
+
+Lunar's translatable fields (`TranslatedText`, `Url`, etc.) are all tied to specific *model
+records* — a product's name, a collection's description. UI labels aren't attached to any model;
+they're static strings the app itself owns. `laravel-translation-loader` is Laravel's own
+`__()`/`trans()` mechanism with a DB-backed source layered on top of the normal file-based one —
+no new helper to learn, no bespoke table shape.
+
+**Nothing existing breaks.** The package's `TranslationLoaderManager` *extends* Laravel's
+`FileLoader` and merges DB translations on top of file-based ones
+(`array_replace_recursive()`) — Filament's own vendor `lang/en/product.php`-style strings
+keep working exactly as before. The package registers itself via Laravel's standard Composer
+package auto-discovery (`extra.laravel.providers` in its own `composer.json`) — nothing needed
+in `CoreServiceProvider` to wire it up.
+
+### Usage
+
+```blade
+{{ __('storefront.nav.cart') }}
+{{ __('storefront.product.add_to_cart') }}
+```
+
+`group` is `storefront` for e-shop UI labels — kept separate from Lunar/Filament's own `lunar::`
+namespaced groups so nothing collides. `__()` resolves the translation for whatever
+`App::getLocale()` currently is, which `LocaleMiddleware` already sets per-request (see
+"Behavior" above) — no extra wiring needed between the two systems.
+
+### Fallback locale follows the store's default language, not `config('app.fallback_locale')`
+
+`spatie/laravel-translation-loader`'s stock `LanguageLine::getTranslation()` falls back to
+`config('app.fallback_locale')` — a static `.env` value — when a key has no text for the current
+locale. That's a second, disconnected "default language" concept: an admin changing the default
+language via the Filament **Languages** resource has no effect on it, so an untranslated label
+could silently fall back to the wrong language.
+
+`Modules\Core\Localization\Models\LanguageLine` overrides `getTranslation()` to fall back to
+`LanguageCache::defaultLocale()` instead — the same `languages.default` flag `LocaleMiddleware`
+already treats as the single source of truth. It's swapped in via
+`config('translation-loader.model')` (the package's own documented extension point for
+"any model that extends `LanguageLine`"), set in `LocalizationServiceProvider::register()` so it
+wins regardless of provider boot order (Laravel's `mergeConfigFrom()` only fills in config keys
+not already set, so an explicit `register()`-time set always beats the package's own default).
+No consuming app configuration needed — this is automatic once `LocalizationServiceProvider` is
+registered.
+
+### Seeding
+
+A starter set of common e-shop labels (`nav.*`, `cart.*`, `product.*`, `auth.*`, `search.*`,
+`review.*`, `shop.*`, `pagination.*`, English + Greek) lives in
+`Modules\Core\Localization\Services\StorefrontLabels::all()` — kept as its own class, separate
+from the seeding logic, so the label list can be scanned/diffed without wading through the
+seeding mechanics.
+
+`Modules\Core\Command\InstallLunarCommand` (overrides Lunar's own `lunar:install`) seeds them via
+a **per-key upsert**, not an all-or-nothing "only seed if the group is empty" guard: a key already
+present in the database — including one an admin has since edited via the Filament **Language
+Lines** resource — is left untouched; only keys missing entirely are created. This is what makes
+it safe to add new keys to `StorefrontLabels::all()` later and re-run `lunar:install` on an
+already-installed store, without either silently skipping the new keys (the old guard's behavior)
+or reverting an admin's edits back to the hardcoded default (what a naive `updateOrCreate` would
+do). New writes go through `TranslationService::create()`, so the usual cache-invalidation and
+activity-log events fire for them too.
+
+### Admin UI
+
+`Modules\Core\Localization\Filament\Resources\LanguageLineResource` (registered in
+`CorePlugin`, under the panel's Settings group) lists/searches/filters `language_lines` and
+edits each row's `group`, `key`, and one text input per row currently in `lunar_languages` —
+the locale columns are generated dynamically from `Language::query()->pluck('code')`, so adding
+a third language automatically adds a third input, no resource changes needed.
+
+### `TranslationService` — writes go through here, not the model directly
+
+`Modules\Core\Localization\Services\TranslationService` wraps create/update/delete on `LanguageLine` and
+dispatches a domain event after each write, following this project's standard event-driven
+pattern (see `modules.md`'s "Splitting Service Providers" / event-listener convention —
+the same shape as `Modules\Core\Auth\Events\UserCreated`):
+
+```php
+use Modules\Core\Localization\Services\TranslationService;
+
+app(TranslationService::class)->create('storefront', 'nav.wishlist', [
+    'en' => 'Wishlist',
+    'el' => 'Λίστα Επιθυμιών',
+]);
+
+app(TranslationService::class)->update(
+    $languageLine,
+    'storefront',
+    'nav.wishlist',
+    ['en' => 'Wishlist ♥', 'el' => 'Λίστα Επιθυμιών ♥'],
+);
+
+app(TranslationService::class)->delete($languageLine);
+```
+
+`update()` takes the full `group`/`key`/`text` state, not just `text` — a rename is a normal
+update, not a special case. `TranslationCreated`, `TranslationUpdated` (carries the full
+`{group, key, text}` snapshot from *before* the update, so a listener can tell a rename from a
+text edit), and `TranslationDeleted` are dispatched from `Modules\Core\Localization\Events`. Two
+listeners are wired in `Modules\Core\Providers\LocalizationServiceProvider` for all three events:
+
+- **`FlushTranslationCache`** — `LanguageLine::boot()` already flushes the cache for the
+  *current* group's locales present after a save, but misses two cases on update: locales a save
+  *removed* from `text` (e.g. dropping the `el` key leaves `storefront.el` stale), and a changed
+  `group`/`key` (the *old* group's cached array is never told a row left it). This listener
+  flushes every group+locale combination touched by either the old or new state, so nothing —
+  including the group a row was renamed away from — can remain stale.
+- **`LogTranslationActivity`** — records the change via `Modules\Core\Logging\ActivityLogService`
+  on the `lunar` activity log channel, same `created`/`updated`/`deleted` shape as every other
+  domain write in this project. A rename shows up in the log as an `old`/`attributes` diff across
+  `group`, `key`, and `text` together, not just a text diff.
+
+The Filament resource's Create/Edit/Delete pages route through `TranslationService` (via
+`handleRecordCreation`/`handleRecordUpdate`/the delete action's `->action()` override) rather
+than Filament's default direct-model calls, so **every** edit made in the admin UI — including a
+bare `group`/`key` rename with no `text` change — dispatches `TranslationUpdated` and is both
+cache-invalidated and audit-logged.

 - **`Attribute.position` is per-group, and the panel sorts by it.** Hardcoding `position => 1` for multiple new attributes in the same group makes their order undefined/collide with existing attributes at position 1. Compute `max('position') + 1` per group instead.
 - **Currency `decimal_places` isn't always 2.** A seeded/demo currency can have the wrong value (seen: EUR seeded with `decimal_places = 1`), which silently corrupts every price display (`€16.50` renders as `165`). If prices look wrong by a factor of 10, check the currency row before assuming the price-writing code is broken.
+- **`Builder::paginateRaw()`'s `items()` is not a hit list on the Meilisearch driver.** It contains the *entire* raw response (`hits`, `query`, `processingTimeMs`, `hitsPerPage`, `page`, `totalPages`, `totalHits`) as one associative array. Treating `$paginator->items()` as a plain list (e.g. `collect($paginator->items())->values()`) silently produces 7 elements — the real hits array happens to land first, the rest are stray scalars from the other response keys — no error, just corrupted data. Pull `$paginator->items()['hits']` explicitly. `total()`/`perPage()`/`currentPage()`/`lastPage()` on the paginator are unaffected. See `Modules\Core\Catalog\Services\ProductService` / `docs/product-listing.md`.
+- **`ProductOption`/`ProductOptionValue::$name` is not `attribute_data` — `translateAttribute('name')` silently returns null for them.** Unlike `Product`/`Collection`/`Brand`, their translated `name` is a plain locale-keyed array cast (`AsArrayObject`) directly on the column, not stored in `attribute_data`. `HasTranslations::translateAttribute()` only reads `attribute_data`, so calling it on these two models compiles fine and returns `null` with no error — read the array directly instead (`$value->name[$locale] ?? ...`). See `Modules\Core\Catalog\Services\ProductIndexer::translatedName()`.
+- **A running `queue:work` process does not pick up an edited/newly-added Scout indexer class.** It loads PHP classes once at boot and keeps them for the process's lifetime. Symptoms: reindexing commands succeed with no errors, calling `toSearchableArray()` directly (e.g. via `artisan tinker`, which always boots fresh) returns the new fields correctly, but documents written via `$model->searchable()` through the live queue are still missing them. Restart the queue worker after deploying an indexer change — no code fix needed.
+- **`CartSession::current()` returns `null` for a fresh visitor by default.** `cart_session.auto_create` defaults to `false`, so nothing auto-creates a cart just from checking `current()`. Use `CartSession::manager()` (force-creates) for an "add to cart" flow, or rely on the fact that `add()`/`remove()`/etc. auto-create via `__call` forwarding (next entry) — don't gate an add-to-cart button on `current() !== null`, it will be null for every guest who hasn't added anything yet.
+- **`CartSession`'s facade/interface don't declare `add()`, `remove()`, `updateLine()`, `clear()`, etc. at all — they work anyway, via `__call` magic.** `CartSessionManager::__call()` forwards any undeclared method call straight to the underlying `Cart` model (auto-creating one first if needed). So `CartSession::add($variant, 2)` genuinely works, but neither the facade's `@method` docblock nor `Lunar\Base\CartSessionInterface` mention it — reading either in isolation makes it look unsupported. Trust the manager's source (`Lunar\Managers\CartSessionManager`), not the interface, which is also missing several real methods (`manager()`, `createOrder()`, the shipping-estimate methods) and has a stale signature for `current()`.
+- **`Cart::calculate()` is a no-op if totals already look populated — even right after you mutated lines with raw Eloquent.** It's memoized via `isCalculated()` (true when `total` and every line's `total` are non-blank). Every built-in mutator (`add`, `remove`, `updateLine`, `clear`, `associate`, …) already calls `$this->refresh()->recalculate()` to force past this memo — but custom code that touches `CartLine` rows directly (raw `update()`, a queued job, a migration) must call `$cart->recalculate()` itself, or `total`/`subTotal`/etc. silently stay stale.
+- **`CartLine`'s computed properties (`unitPrice`, `subTotal`, `total`, `taxAmount`, …) are plain public properties, not DB columns or Eloquent attributes.** A raw `CartLine::find($id)` (no `calculate()` having run on its owning cart) has all of these as `null`/unset — they only populate as a side effect of the owning `Cart`'s pipeline running. Don't read them off a line fetched outside of `CartSession`/`Cart::add()` etc. without calling `$cart->calculate()` first.
+- **Logging out deletes the cart by default.** `CartSessionAuthListener::logout()` calls `CartSession::forget()`, and `cart_session.delete_on_forget` defaults to `true` — so a logged-in customer's cart is soft-deleted the moment they log out, guest or not. Set `delete_on_forget` to `false` in `config/lunar/cart_session.php` if carts should survive a logout.
+- **Lunar dispatches no cart events at all** — no "item added," "cart created," "line removed," nothing under `Lunar\Events\Cart*`/`CartLine*` exists (unlike products/collections, which have their own Scout indexing hooks). The only reactive surface is `CartLineObserver` (`creating`/`updating`, and it only validates the purchasable type — doesn't dispatch anything). If a feature needs to react to cart changes (reindexing, abandoned-cart notifications, analytics), it has to be built from scratch on plain Eloquent model events (`CartLine::created`, etc.) — there's no Lunar-native pattern to hook into.
+- **No Filament admin resource exists for `Cart`/`CartLine`.** Carts aren't visible anywhere in the admin panel except indirectly through an order's `cart` relationship once that cart has become an order. Don't assume there's an admin cart-viewer to check against when debugging — there isn't one.

+# Product Listing
+
+`Modules\Core\Catalog\Services\ProductService` provides catalog browsing/filtering AND single-product
+lookup for a storefront — `list()`, `getById()`, `getBySlug()` — all reading directly from the
+Meilisearch index rather than the database. One data source for everything this service does.
+
+This is separate from `Modules\Core\Catalog\Services\ProductSearchService` (see `product-search.md`), which
+handles free-text query search. `ProductService` is for browsing/lookup without a search term.
+
+---
+
+## Why it reads from the index, not the database
+
+Every method here reads Meilisearch documents directly and returns plain arrays — never Scout's
+`->get()`, which would re-hydrate Eloquent models from the database. This means the index has to
+carry everything a detail page needs (variants, prices, options, media, reviews — see below), not
+just the trimmed fields a listing page needs. `Modules\Core\Catalog\Services\ProductIndexer` is built to
+carry that full shape.
+
+---
+
+## Usage
+
+```php
+use Modules\Core\Catalog\DTOs\ProductFilters;
+use Modules\Core\Catalog\Services\ProductService;
+use Modules\Core\Catalog\Enums\ProductSort;
+
+$service = app(ProductService::class);
+
+// List everything, paginated — returns a real Illuminate\Pagination\LengthAwarePaginator,
+// built from the localized Meilisearch hits (not Scout's own paginateRaw() result — see
+// "Meilisearch driver quirk" below), so it behaves like any other Laravel paginator.
+$products = $service->list(perPage: 24, page: 1);
+
+// Filter by collection, brand, price range, and/or stock
+$products = $service->list(
+    filters: new ProductFilters(collectionId: 17, minPrice: 10.0, maxPrice: 50.0, inStockOnly: true),
+    perPage: 24,
+    page: 1,
+);
+
+// Sort — cheapest/priciest first, or newest first. Omit for Meilisearch's default
+// relevance ordering (irrelevant here since the query is always empty).
+$products = $service->list(perPage: 24, page: 1, sort: ProductSort::PriceAsc);
+
+$products->items();            // array of Meilisearch documents (plain arrays, not models)
+$products->total();
+$products->perPage();
+$products->currentPage();
+$products->lastPage();
+$products->links();            // in a Blade view — renders pagination links as usual
+
+// Single product, by primary key
+$product = $service->getById(367);   // array, or null if not found
+
+// Single product, by URL slug (any locale — slugs are indexed across all languages)
+$product = $service->getBySlug('erotika-mprelok');   // array, or null if not found
+
+// Facet counts for a sidebar — value => matching product count, scoped to whatever
+// $filters is passed. Does NOT exclude the faceted field itself from $filters — see
+// facets()'s docblock for why, and how to build a standard "every option's count,
+// unaffected by that option's own currently-selected value" sidebar.
+$brandCounts = $service->facets('brand', filters: new ProductFilters(collectionId: 17));
+// ['3Dealer.gr - 3D printed creations' => 48, 'Kraniou Topos - 3D printed creations' => 135]
+
+// Min/max price across matching products, for sizing a price-range slider.
+// minPrice/maxPrice are ALWAYS excluded from the filter driving this (unlike
+// facets(), which doesn't auto-exclude) — the slider's own bounds shouldn't shrink
+// to whatever range is currently selected on it. Other filters (collectionId,
+// brand, inStockOnly) still apply normally.
+$range = $service->priceRange(new ProductFilters(collectionId: 17));
+// ['min' => 0.0, 'max' => 120.0]
+```
+
+All `ProductFilters` fields are optional; only the ones set are added to the Meilisearch query.
+
+`facets()` only makes sense on discrete-value filterable fields (`brand`, `in_stock`) — a numeric
+field like `price` would return one "facet" per exact price, not a usable range bucket. Use
+`priceRange()` for `price` instead, which reads Meilisearch's `facetStats` (min/max), a different
+feature from `facetDistribution`.
+
+---
+
+## Stock goes stale between orders
+
+`in_stock` reflects `ProductVariant::stock`/`purchasable` as of the **last reindex**, not live
+inventory. Nothing in this codebase currently reindexes a product when an order decrements its
+stock — that's a cart/checkout concern, not something `ProductIndexer` can solve on its own (see
+`Modules\Core\Catalog\Observers\ProductOptionReindexObserver` for the equivalent pattern once an
+order → stock → reindex pipeline exists to hook into). Until then, `in_stock`/`product_count` can
+drift from the database the same way every other indexed field already can between writes.
+
+---
+
+## Fields this depends on: `Modules\Core\Catalog\Services\ProductIndexer`
+
+Lunar's own `Lunar\Search\ProductIndexer` only carries listing-grade fields (name, description,
+status, brand, a single thumbnail, skus) and marks just `__soft_deleted`, `skus`, `status` as
+filterable. `Modules\Core\Catalog\Services\ProductIndexer` extends it to add everything `ProductService`
+needs, listing and detail alike:
+
+| Field | Source | Notes |
+|---|---|---|
+| `id` | — | Newly marked **filterable** — needed for `getById()`'s `id = "..."` filter; Meilisearch doesn't filter on the primary key by default. |
+| `collections` | `$product->collections` | Array of `{id, name}` — directly assigned collections only, `name` is the translated collection name. Not filterable — see `collection_ids`. |
+| `collection_ids` | `$product->collections` + `->ancestors` | Filterable. Flat array of every directly-assigned collection's id, unioned with all of its ancestors' ids. `ProductFilters(collectionId: ...)` filters against this field, not `collections`, since products are typically attached only to leaf collections — a plain direct-match filter would never return anything for a parent/root category page. |
+| `slugs` | `$product->urls->pluck('slug')` | Filterable. Every locale's `Url::slug` for the product, so `getBySlug()` resolves purely from the index — no database read. |
+| `price` | Cheapest variant's base price | Filterable. Float in major units (e.g. `19.99`, not `1999`). Base price only — no customer group, default currency (`Currency::getDefault()`) only. `null` if the product has no priced variant yet, so it's excluded from range filters rather than treated as free. |
+| `brand` | Already indexed by Lunar's base indexer | Newly marked **filterable** — it existed in the document already, just wasn't usable in a `filter` clause. |
+| `tags` | `$product->tags->pluck('value')` | Display only. |
+| `media` | `$product->media` | Full gallery (id/url/thumb per image), not just the single thumbnail Lunar's base indexer sends. |
+| `variants` | `$product->variants` | Per variant: `id`, `sku`, `stock`, `purchasable`, `options` (option/value names, in the current locale), `prices` (per currency/customer group), `media` (variant-specific images). |
+| `reviews` | `Modules\Core\Review\Models\ProductReview` | `{items, count, average_rating}` — see "Reviews" below. |
+| `in_stock` | `$model->variants` | Filterable boolean. `true` if ANY variant currently passes `ProductVariant::canBeFulfilledAtQuantity(1)` — Lunar's own purchasability rule (`purchasable === 'always'` ignores stock entirely; `in_stock` checks `stock` alone; anything else checks `stock + backorder`). Only as fresh as the last reindex — see "Stock goes stale" below. |
+
+`name`/`description` (and any other `TranslatedText` attribute) are indexed per-locale — see
+"Locale resolution" below for how `ProductService` resolves them down to one value per request.
+
+**`ProductOption`/`ProductOptionValue` names need a different translation accessor.** Unlike
+`Product`/`Collection`/`Brand`, their `name` is a plain locale-keyed array cast, not
+`attribute_data` — Lunar's `translateAttribute('name')` silently returns `null` for them. The
+indexer's `translatedName()` reads the array directly instead. See `docs/lunar.md` "Gotchas".
+
+---
+
+## Locale resolution: `name`, `description`, and any other translated attribute
+
+Lunar's base `ScoutIndexer` explodes every `TranslatedText` attribute into one `{handle}_{locale}`
+field per store language at index time (`name_el`, `name_en`, `description_el`, ... — and the same
+for any custom translated attribute a store adds, e.g. `seo_title`/`seo_description`). Every raw
+document in Meilisearch carries all of them side by side, since a document is written once but
+read across many different-locale requests.
+
+`ProductService` resolves these back down to a single value per request. For every result it
+returns (`list()`'s items, `getById()`, `getBySlug()`), it:
+
+1. Reads which `Product` attributes are `TranslatedText` from `Lunar\Base\AttributeManifest` — the
+   same source Lunar's own indexer reads — rather than a hardcoded `['name', 'description']` list,
+   so a store's own custom translated attributes are picked up automatically with no change here.
+2. For each one, resolves `{handle}_{currentLocale}`, falling back to `{handle}_{storeDefaultLocale}`
+   (`LanguageCache::defaultLocale()`) if the current locale has no translation — e.g. a product with
+   no English copy yet still shows its Greek name on `/en/` rather than rendering blank.
+3. Assigns the result to a plain `{handle}` key and **strips every raw `{handle}_{locale}` key** —
+   callers only ever see `$product['name']`/`$product['seo_title']`/etc., never the per-locale
+   fields the index actually stores.
+
+`description` and other translated attributes are otherwise indexed as-is, including any HTML
+markup (e.g. from a Shopify `Body (HTML)` import) — **not stripped**. Any view rendering a
+description sourced from `ProductService`'s results must treat it as trusted HTML.
+
+---
+
+## Reviews
+
+`Modules\Core\Review\Models\ProductReview` (`product_reviews` table) is indexed per-product under
+a single `reviews` key: `{items, count, average_rating}` — `items` is the array of reviews,
+`average_rating` is rounded to 1 decimal (`null` if the product has no reviews). Only public-safe
+fields are included on each item — **`reviewer_email` is deliberately excluded**, it's PII with no
+storefront use. `reply`/`replied_at` (the staff response) are included, since they're meant to be
+shown alongside the review.
+
+A review is created/edited independently of its product (a customer submission, a staff reply)
+— its own save doesn't touch the `Product` row, so the product's own model events never fire.
+`Modules\Core\Providers\ReviewServiceProvider` listens on `ProductReview`'s `created`/`updated`/
+`deleted` events and calls `$review->product->searchable()`, so the parent product's document
+stays current without waiting for the next full reindex. This provider must be registered in
+`composer.json`'s `extra.laravel.providers` (already done in this repo) — see `docs/modules.md`
+"Provider Registration Pitfalls" for what happens if a provider like this is ever added but not
+registered.
+
+---
+
+## Multi-variant products and price
+
+A product's `price` is its *cheapest* variant's price ("from €19.99" style), not every variant's
+price. A price-range filter matches based on that single minimum — a product with one cheap
+variant and several expensive ones will match a low-price-range filter even though most of its
+variants don't.
+
+---
+
+## Sorting
+
+`ProductSort` (`Modules\Core\Catalog\Enums\ProductSort`) is a fixed enum of supported sort orders —
+`PriceAsc`, `PriceDesc`, `Newest` — each mapping to a Meilisearch `sort` clause against a field
+`Modules\Core\Catalog\Services\ProductIndexer::getSortableFields()` marks sortable (`price`, plus
+`created_at`/`updated_at`/`skus`/`status` inherited from Lunar's base indexer). Adding a new
+`ProductSort` case requires adding the matching field to `getSortableFields()` and re-syncing (see
+below) — sortable attributes are index settings, not computed per-query, same as filterable ones.
+
+Omitting `sort` leaves Meilisearch's default ordering, which is meaningless here since `list()`
+always searches with an empty query string (`Product::search('')`) — there's no relevance score to
+rank by, so results come back in whatever order the index returns them absent an explicit sort.
+
+---
+
+## Registering the indexer
+
+Not automatic — an app opts in via its own `config/lunar/search.php`:
+
+```php
+'indexers' => [
+    Lunar\Models\Product::class => Modules\Core\Catalog\Services\ProductIndexer::class,
+    // ...other model indexers unchanged
+],
+```
+
+## Re-syncing after this change
+
+Filterable attributes are Meilisearch index settings, not computed per-query — changing them
+requires re-syncing settings and reindexing existing documents:
+
+```bash
+php artisan lunar:meilisearch:setup
+php artisan lunar:search:index "Lunar\Models\Product" --refresh
+```
+
+**If `SCOUT_QUEUE=true`, restart the queue worker after deploying an indexer change.** A running
+`queue:work` process loads PHP classes once at boot and keeps that code in memory for its entire
+lifetime — it does not pick up an edited/newly-deployed indexer class. Symptoms: reindexing
+commands succeed with no errors, `Product::toSearchableArray()` returns the new fields correctly
+when called directly (e.g. via `artisan tinker`, which always boots fresh), but documents written
+via `$model->searchable()` through the live queue are still missing the new fields. Restarting the
+queue worker (`docker compose restart queue`, or equivalent) resolves it — no code change needed.
+
+---
+
+## Meilisearch driver quirk: `paginateRaw()`'s `items()` is not a list of hits
+
+For the Meilisearch engine specifically, Scout's `Builder::paginateRaw()` puts the **entire raw
+response** (`hits`, `query`, `processingTimeMs`, `hitsPerPage`, `page`, `totalPages`, `totalHits`)
+into the paginator's `items()`, not a plain array of documents. Calling `$paginator->items()`
+and treating it as a list (e.g. `collect($paginator->items())->values()`) silently produces a
+7-element array whose first element happens to be the real hits and the rest are stray scalars
+from the other response keys — no error, just wrong data leaking into what looks like a normal
+list. `ProductService::list()` pulls `$paginator->items()['hits']` explicitly to avoid this;
+`$paginator->total()`/`perPage()`/`currentPage()`/`lastPage()` are unaffected and safe to use
+as-is.

+# Product Option Types
+
+Lunar's `ProductOption`/`ProductOptionValue` are generic by design — a "Color" option
+and a "Size" option are both just a handle, a translated name, and a list of values.
+Each `ProductOptionValue` carries a free-form `meta` jsonb column, but nothing in
+Lunar's own admin UI exposes it — there's no way for an admin to, say, attach a hex
+code to a "Red" value without editing the database directly.
+
+`Modules\Core\Catalog\Contracts\ProductOptionTypeInterface` describes how a category
+of option behaves — what structured data its values carry in `meta`, and how an
+admin edits that data — without introducing a new model. `ProductOption`/
+`ProductOptionValue` stay exactly as Lunar defines them.
+
+---
+
+## Registering a type
+
+A shop registers a type class from its own service provider's `boot()`, the same
+shape as `Modules\Core\Notification\NotificationRegistry`:
+
+```php
+use Modules\Core\Catalog\Services\ProductOptionTypeManager;
+
+ProductOptionTypeManager::get()->register([
+    \App\ProductOptions\ColorOptionType::class,
+]);
+```
+
+Not a published config array — the mapping isn't per-`ProductOption`, so there's
+nothing for a shop to *key* by. Instead, an admin picks a type per-option from a
+dropdown on the `ProductOption` edit form itself (see below); the choice is stored
+in `ProductOption::meta['option_type']`, deliberately **not** tied to the option's
+`handle` (a shop's own handle naming — transliterated Greek, legacy import slugs —
+shouldn't have to match a type's key).
+
+A `ProductOption` with no type selected behaves exactly as stock Lunar does — plain
+name/position, no extra meta form.
+
+---
+
+## Writing a type
+
+```php
+namespace App\ProductOptions;
+
+use Filament\Forms\Components\ColorPicker;
+use Modules\Core\Catalog\Contracts\ProductOptionTypeInterface;
+
+class ColorOptionType implements ProductOptionTypeInterface
+{
+    public static function getKey(): string
+    {
+        return 'color';
+    }
+
+    public function getMetaForm(): array
+    {
+        return [
+            ColorPicker::make('meta.hex')
+                ->label('Color')
+                ->required(),
+        ];
+    }
+}
+```
+
+`getMetaForm()` returns Filament form components, keyed under `meta.*` dot notation
+— the path they save to on `ProductOptionValue::meta` (cast as `AsArrayObject`, a
+plain jsonb column). `getKey()` is the identifier used in the admin's "Option Type"
+dropdown and in `ProductOption::meta['option_type']` — it has no relationship to the
+`ProductOption::handle`.
+
+A reference implementation ships at `Modules\Core\Catalog\OptionTypes\ColorOptionType`,
+registered automatically by `Modules\Core\Providers\CatalogServiceProvider` — no shop
+setup needed for it to appear in the "Option Type" dropdown, though an admin still
+has to pick it per-`ProductOption` for it to take effect.
+
+---
+
+## How it's wired into the admin UI
+
+`Modules\Core\Catalog\Services\ProductOptionTypeManager` is a singleton registry:
+- `get(): static` — the shared instance.
+- `register(array $types): void` — registers one or more type classes, keyed
+  internally by `getKey()`.
+- `unregister(string $key): void`
+- `resolve(?string $key): ?ProductOptionTypeInterface` — looks up a registered type
+  by key (or `null` if no key / not found).
+- `all(): array<string, class-string>` — every registered type's class, keyed by
+  `getKey()`.
+
+Two extensions hook into Lunar's admin via its extension system
+(`LunarPanel::extensions([...])`, registered in `CorePlugin`) — no forking of Lunar's
+classes needed:
+
+- `Modules\Core\Catalog\Filament\Extensions\ProductOptionResourceExtension` extends
+  `Lunar\Admin\Filament\Resources\ProductOptionResource`'s own form with a `Select`
+  (`meta.option_type`) listing every enabled type's key. Shown only when at least one
+  type is enabled.
+- `Modules\Core\Catalog\Filament\Extensions\ValuesRelationManagerExtension` extends
+  the "Values" tab's form. Its `extendForm()` reads
+  `$option->meta['option_type']` off the owning `ProductOption`, resolves it via
+  `ProductOptionTypeManager`, and appends `getMetaForm()`'s fields to the stock name
+  field. A `ProductOption` with no type selected gets the stock form unchanged.
+
+---
+
+## Reading the value back
+
+Storefront code reads `ProductOptionValue::meta` like any other jsonb column — e.g.
+`$value->meta['hex']` for a color swatch. `ProductOptionTypeManager` is an admin-side
+concern only (describing *how to edit* the meta); nothing requires the storefront to
+go through it to *read* the meta.

+# Product Search
+
+`Modules\Core\Catalog\Services\ProductSearchService` provides locale-aware full-text product search on
+top of Laravel Scout + Meilisearch.
+
+---
+
+## Why locale-aware search isn't a filter
+
+Lunar's Meilisearch indexer (`Lunar\Search\ScoutIndexer::mapSearchableAttributes()`) flattens
+every translated attribute into **locale-suffixed fields on a single document** — a product with
+a translated `name` produces `name_en`, `name_el`, etc. as separate top-level fields, not
+separate documents per locale and not a filterable `locale` field.
+
+That means "search in Greek" isn't a `->filter('locale = el')` — Meilisearch has no such field to
+filter on. It's a choice of **which fields the query targets**: `name_el`/`description_el`
+instead of `name_en`/`description_en`. This is what Meilisearch's `attributesToSearchOn` search
+parameter controls, exposed through Scout via `Builder::options()`, which passes straight through
+to the underlying Meilisearch client call (`Laravel\Scout\Engines\MeilisearchEngine::performSearch()`
+merges `$builder->options` directly into the search request).
+
+---
+
+## Usage
+
+```php
+use Modules\Core\Catalog\Services\ProductSearchService;
+
+$results = app(ProductSearchService::class)->search('running shoes');
+// or an explicit locale, bypassing App::getLocale():
+$results = app(ProductSearchService::class)->search('running shoes', 'el');
+```
+
+Returns an `Illuminate\Database\Eloquent\Collection` of `Lunar\Models\Product` — Scout's
+`->get()` hydrates real models from the database after the Meilisearch query, so relations
+(`variants`, `brand`, `media`, etc.) are available on the results as normal.
+
+`$locale` defaults to `App::getLocale()` — already set correctly on every storefront request by
+`Modules\Core\Localization\Middleware\LocaleMiddleware` (see `localization.md`), so callers in controllers
+don't need to pass it explicitly.
+
+---
+
+## Missing-translation fallback
+
+If a product was only ever given an English name, `name_el` doesn't exist on that document at
+all (Lunar's indexer only writes a `{handle}_{locale}` field for locales actually present in the
+attribute's stored data — see `ScoutIndexer::mapSearchableAttributes()`). Searching strictly
+against `name_el` would make that product invisible to Greek-locale search, even though it's a
+real catalog item.
+
+To avoid silently hiding incompletely-translated products, `ProductSearchService` targets **both**
+the resolved locale's fields **and** the default language's fields
+(`Lunar\Models\Language::getDefault()->code`) — e.g. searching in `el` targets `name_el`,
+`name_en`, `description_el`, `description_en` together (assuming `en` is the default language).
+A product missing an `el` translation still matches via its `en` fields.
+
+---
+
+## Field list is dynamic, not hardcoded
+
+The set of attribute handles searched (`name`, `description`, or whatever else) comes from
+`Lunar\Facades\AttributeManifest::getSearchableAttributes(Product::morphName())` — the same
+source `ScoutIndexer` itself uses to decide what gets indexed. If an admin marks a new attribute
+searchable in the panel, `ProductSearchService` picks it up automatically; nothing in this class
+needs to change.
+
+---
+
+## Re-syncing after indexer changes
+
+Changing which attributes are searchable, or `ProductIndexer`'s filterable/sortable fields,
+requires re-syncing Meilisearch's index settings and re-indexing existing documents:
+
+```bash
+php artisan lunar:meilisearch:setup
+php artisan lunar:search:index "Lunar\Models\Product" --refresh
+```
+
+`ProductSearchService` itself needs no re-sync when locales change — `attributesToSearchOn` is
+computed per-query from the live language list, not baked into index settings.

+# Cart/Checkout Recovery Strategies — Design Notes
+
+**Status: open design discussion, not scoped or built.** This is a record of the
+reasoning behind an eventual "Recovery Sequences" feature, kept so the discussion doesn't
+have to be re-derived from scratch later. Nothing in this document is implemented.
+
+See `docs/cart.md` for what's actually built today (the four-state cart classification,
+`CartAbandoned`/`CheckoutAbandoned` events, `DetectAbandonedCarts`).
+
+---
+
+## Why Abandoned Cart and Abandoned Checkout need different strategies
+
+Established in `docs/cart.md`: Abandoned Cart (no order ever started) is a weak purchase-intent
+signal and often unreachable (no identity for a true guest). Abandoned Checkout (a draft order
+exists, `placed_at IS NULL`) is a strong intent signal and usually reachable, since checkout
+typically captures an email/address even for a guest.
+
+That difference in intent and reachability drives genuinely different marketing strategy, not
+just a different admin filter:
+
+### Abandoned Cart strategy — re-engagement, not completion
+
+- **On-site retargeting first** (exit-intent popups, "still thinking it over?" banners on
+  return visits) — often the only viable channel, since email may not exist yet.
+- **Ad platform retargeting** (Meta/Google dynamic remarketing) is the dominant channel here
+  specifically because it works off a browser/device signal, not an email address — the one
+  thing reliably available for an anonymous cart.
+- **Soft messaging** ("did you forget something?") rather than urgency-driven — intent is
+  weak, so aggressive discounting is often poor ROI: it trains browsers who were never close
+  to buying to expect a coupon.
+- **Longer, gentler cadence** — a single reminder around 24h, maybe a second a few days out,
+  sometimes trigger-based (a price drop, back-in-stock) rather than a fixed schedule.
+
+### Abandoned Checkout strategy — completion, not re-engagement
+
+- **Speed matters most.** This is where the classic 1h/24h/72h recovery-email cadence lives —
+  conversion drops sharply with delay, since the shopper is often still in a "was about to
+  buy" mental state within the first hour.
+- **Direct, urgency-framed messaging** ("complete your order"), sometimes showing cart
+  contents/total, occasionally a countdown or limited-time incentive on later touches.
+- **Discount escalation pays off here** — a small incentive (free shipping, 10% off) on the
+  2nd/3rd touch is standard, because it's nudging someone who already decided to buy past
+  whatever blocked them (price shock, a broken payment step, indecision on shipping cost) —
+  not manufacturing demand from nothing.
+- **SMS is more viable** — checkout often captures a phone number, and the higher intent
+  justifies a more direct channel than for cart-stage.
+
+---
+
+## The broader strategy space (beyond cadence + discount)
+
+Raised as context for how far a "Recovery Sequence" feature might eventually need to flex,
+without committing to building any of it yet:
+
+**Message-content strategies**
+- Social proof ("X people have this in their cart," reviews shown in the reminder)
+- Scarcity/urgency framing (low-stock count, countdown timer on an offer)
+- Personalized alternatives — a cheaper or complementary item instead of just re-showing the
+  abandoned one, useful when the likely blocker was price
+
+**Channel strategies**
+- Email (the baseline; nothing built yet — see `docs/cart.md`'s "Recovery Sequences" section)
+- SMS — checkout-stage specifically, opt-in required
+- Push notifications — not relevant yet given this project's storefront maturity, noted for
+  completeness
+- On-site remarketing (banner/modal on the shopper's next visit) — doesn't require email at
+  all, arguably the highest-value channel for Abandoned Cart specifically
+- Ad platform sync (pushing abandoned-cart product data to a custom audience for paid retargeting)
+
+**Escalation/segmentation strategies**
+- Value-based branching — a high-value abandoned checkout might skip straight to a bigger
+  incentive rather than waiting through a full ladder
+- Repeat-abandoner suppression — a customer who's abandoned 3+ times without ever completing
+  either stops receiving emails (fatigue/spam risk) or gets a different tactic (e.g. a "what
+  stopped you?" survey) instead of another discount
+- New vs. returning customer branching — a first-time visitor's abandoned cart might warrant
+  "welcome discount" framing instead of a generic recovery email, since the blocker was
+  likely trust/unfamiliarity rather than price
+
+**Timing refinement**
+- Time-of-day/timezone-aware sending (don't fire a touch at 3am local time even if the delay
+  technically elapsed)
+- Cart-content-triggered timing — a fast-moving/low-stock item might warrant an earlier, more
+  urgent first touch than a cart of always-in-stock staples
+
+---
+
+## First-pass feature shape (discussed, not finalized)
+
+An admin defines, independently per abandonment type (Abandoned Cart, Abandoned Checkout), an
+ordered sequence of **touches**. Each touch is three ideas:
+
+1. **How long to wait** since the abandonment began
+2. **What offer to attach**, optional — reusing whatever `Discount` already exists in the
+   system rather than inventing a new pricing concept
+3. **A label**, so staff can see what a touch represents in the admin UI
+
+The system continuously re-evaluates every abandoned cart/checkout against its sequence, and
+when a cart becomes due for the next touch it hasn't had yet, that becomes a signal — this
+feature's responsibility ends there. Actually sending anything (email, SMS, on-site banner) is
+explicitly out of scope for this feature; something else, not yet designed, would consume that
+signal.
+
+### What this requires that isn't built yet
+
+- **A fixed "abandonment began at" timestamp**, captured once and never re-derived — a
+  sequence needs to schedule touches from a stable starting point, not from `Cart::updated_at`,
+  which keeps moving every time the cart (or its own bookkeeping) is written to. This is the
+  same underlying issue as the known bug in `docs/cart.md`'s "Abandonment detection" section —
+  fixing that bug properly (freezing the abandonment moment) is very likely a prerequisite for
+  this feature, not a separate concern.
+- **Re-evaluation, not one-shot detection** — `DetectAbandonedCarts` today marks a cart
+  abandoned once and stops; a sequence needs a cart to be revisited on every scheduler run to
+  check "which touch, if any, is now due," for as long as it stays unrecovered.
+
+### Still undecided
+
+- **Which concern this belongs under.** Not `Cart` (it's not a cart-mechanics concern) —
+  candidates raised: a new `Recovery` concern, or `Marketing`. Not decided.
+- **How far the touch model needs to flex.** The three-idea shape above (delay, discount,
+  label) covers cadence + discount escalation cleanly, but doesn't yet accommodate channel
+  choice, value-based branching, or segment targeting from the broader strategy list above.
+  Whether those get folded into the touch model, layered on top some other way, or deliberately
+  left out of v1 is unresolved.
+- **Whether "recovery" is cart/checkout-specific at all**, or a more general "scheduled
+  customer touch based on a triggering condition" mechanism that cart/checkout abandonment
+  happens to be the first use case for.
