+## [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`).

 - **`ProductOption.handle` must be unique and non-null if a product has more than one option.** Lunar's Filament variant-switcher widget does `SelectFilter::make($option->handle)` per option — two options with a `null`/matching handle throws "Filter must have a unique name" as a 500 when opening that product's variant pricing page. Always derive a slug and check uniqueness.
 - **`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.

+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.

+## Sorting
+
+`ProductSort` (`Modules\Core\Product\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\Product\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\Search\ProductIndexer::class,
+    Lunar\Models\Product::class => Modules\Core\Product\Services\ProductIndexer::class,
     // ...other model indexers unchanged
 ],

+# 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\Product\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\Product\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\Product\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\Product\OptionTypes\ColorOptionType`,
+registered automatically by `Modules\Core\Providers\ProductServiceProvider` — 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\Product\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 $key): ?ProductOptionTypeInterface` — looks up a registered type
+  by key (or `null` if no key / not found).
+- `all(): array<string, class-string>` — every registered type's class, keyed by
+  `getKey()`.
+
+Two extensions hook into Lunar's admin via its extension system
+(`LunarPanel::extensions([...])`, registered in `CorePlugin`) — no forking of Lunar's
+classes needed:
+
+- `Modules\Core\Product\Filament\Extensions\ProductOptionResourceExtension` extends
+  `Lunar\Admin\Filament\Resources\ProductOptionResource`'s own form with a `Select`
+  (`meta.option_type`) listing every enabled type's key. Shown only when at least one
+  type is enabled.
+- `Modules\Core\Product\Filament\Extensions\ValuesRelationManagerExtension` extends
+  the "Values" tab's form. Its `extendForm()` reads
+  `$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.
