+# Plan: Add `catalog.storeproduct.*` methods support (issue #584)
+
+## Context
+
+The `catalog.storeproduct` entity represents product stock/quantity records per warehouse
+(store). It is a **read-only** entity in the Bitrix24 REST API — only three methods exist,
+confirmed via `mcp__Bitrix24_REST_API__bitrix-method-details` and a live webhook call against
+`https://ignatenko.bitrix24.com`:
+
+- `catalog.storeproduct.get(id)` — returns a single `storeProduct` record by its record id.
+  https://apidocs.bitrix24.com/api-reference/catalog/store-product/catalog-store-product-get.html
+- `catalog.storeproduct.list(select, filter, order)` — returns a filtered/ordered list of
+  `storeProduct` records plus `total`. The `order` parameter is not documented in the
+  "Parameters" table but works in practice (verified live) and is used in the official PHP
+  example, matching the `ProductPropertySection::list()` precedent.
+  https://apidocs.bitrix24.com/api-reference/catalog/store-product/catalog-store-product-list.html
+- `catalog.storeproduct.getFields()` — returns field metadata wrapped in a `storeProduct` key
+  (same envelope shape as `catalog.priceType.getFields`).
+  https://apidocs.bitrix24.com/api-reference/catalog/store-product/catalog-store-product-get-fields.html
+
+No `add`/`update`/`delete` methods exist for this entity (verified against docs — stock is
+managed via `catalog.document.*` warehouse accounting documents, not directly).
+
+### Confirmed field set (live response + docs match exactly)
+
+| Field | Bitrix type | PHP annotation | Nullable |
+|---|---|---|---|
+| `id` | integer | `int` | no |
+| `productId` | integer | `int` | no |
+| `storeId` | integer | `int` | no |
+| `amount` | double | `float` | no |
+| `quantityReserved` | double | `float\|null` | yes (observed `null` live) |
+
+All fields are `isReadOnly: true` per `getFields()`.
+
+### Response envelope keys
+
+- `get` → `result.storeProduct` (single object)
+- `list` → `result.storeProducts` (array) + `result.total` (sibling key, not nested)
+- `getFields` → `result.storeProduct` (field-description map, same key name as `get` but
+  different shape — this matches the `catalog.priceType.getFields` → `result.priceType`
+  precedent, so a dedicated `StoreProductFieldsResult` class is required; the generic
+  `Core\Result\FieldsResult` cannot be reused because it reads the top-level `result` directly)
+
+### Architectural decisions
+
+- **No Batch class.** The entity is read-only (`get`/`list`/`getFields` only, no
+  add/update/delete), matching the existing `ProductPropertySection` and `Measure` scopes in
+  this codebase, neither of which has a `Batch.php` or constructor-injected batch dependency.
+  No other read-only Catalog scope uses `Core\Batch::getTraversableList()` for bulk `list`
+  reading, so this plan does not introduce one either — consistent with precedent.
+- **Result-item generator not used.** `docs/open-api/openapi.json` (rebuilt via
+  `make oa-schema-build`) has no `catalog_storeproduct` schema entry, so
+  `b24-dev:result-item-generator` has no source to run against. `StoreProductItemResult` is
+  written manually following the `PriceTypeItemResult` / `ProductPropertySectionItemResult`
+  pattern (5 flat scalar fields, no nested objects, no dates — no `SelectBuilder`/`ItemBuilder`
+  generator applies either, since those are for CRM smart-process-like entities with typed
+  builders and this scope's `list()`/`getFields()` are hand-rolled elsewhere in Catalog too).
+- Field naming stays exactly as returned by the API (`productId`, `storeId`, `quantityReserved`
+  — camelCase, not the CRM `UPPER_SNAKE` convention), matching `PriceTypeItemResult`.

+    }
+}
+```
+
+Confirmed accessor by precedent: `Catalog\Measure\Result\MeasuresResult::getTotal()` and

+`getResponseData()->getPagination()->getTotal()`, not via `getResult()['total']`. Follow the

+
+Mirrors `tests/Unit/Services/Catalog/ProductPropertySection/Service/ProductPropertySectionTest.php`:
+mock `CoreInterface::call` and assert exact method name + params for `get`, `list` (with args
+and with defaults), `getFields`.
+
+### 7. `tests/Integration/Services/Catalog/StoreProduct/Service/StoreProductTest.php`
+

+use PHPUnit\Framework\Attributes\TestDox;
+use PHPUnit\Framework\TestCase;
+
+#[CoversClass(StoreProduct::class)]
+class StoreProductTest extends TestCase
+{
+    private StoreProduct $storeProductService;
+
+    #[TestDox('test StoreProduct::list finds existing storeProduct records')]
+    public function testList(): void
+    {
+        $items = $this->storeProductService->list()->getStoreProducts();
+        $this->assertNotEmpty($items, 'integration portal must have at least one product with stock');

+
+Fixture strategy confirmed live: the integration portal already has 1 store (`id=1`,
+`title=Warehouse`) and at least one `storeProduct` row (`productId=133`, `storeId=1`,
+`amount=10`), so no `setUp()`/`tearDown()` fixture creation is needed — tests read existing
+stock data directly via `list()`, consistent with the entity being read-only.
+
+### 8. `tests/Integration/Services/Catalog/StoreProduct/Result/StoreProductItemResultTest.php`
+
+Mandatory annotation/type-cast test, following the template in `SKILL.md`:
+
+```php
+<?php
+
+declare(strict_types=1);
+
+namespace Bitrix24\SDK\Tests\Integration\Services\Catalog\StoreProduct\Result;
+
+use Bitrix24\SDK\Services\Catalog\StoreProduct\Result\StoreProductItemResult;

+
+    private StoreProduct $storeProductService;
+
+    #[Test]
+    #[TestDox('all fields in StoreProductItemResult are annotated in phpdoc and match with raw api response')]
+    public function testAllFieldsAreAnnotated(): void
+    {
+        $rawItem = $this->storeProductService->list()->getCoreResponse()
+            ->getResponseData()->getResult()['storeProducts'][0];
+
+        $this->assertBitrix24AllResultItemFieldsAnnotated(
+            array_keys($rawItem),
+            StoreProductItemResult::class
+        );
+    }
+
+    #[Test]
+    #[TestDox('all fields in StoreProductItemResult have valid type casting in magic getters')]
+    public function testAllFieldsHasValidTypeCastingInMagicGetters(): void
+    {
+        $item = $this->storeProductService->list()->getStoreProducts()[0];
+        $this->assertBitrix24ResultItemFieldsTypeCastMatchAnnotations(
+            $item,
+            StoreProductItemResult::class
+        );
+    }
+
+    #[\Override]
+    protected function setUp(): void
+    {
+        $this->storeProductService = Factory::getServiceBuilder()->getCatalogScope()->storeProduct();
+    }
+}
+```
+
+Depends on the pre-existing `storeProduct` record on the integration portal (confirmed live:
+portal returns one row for `productId=133`/`storeId=1`), so no setUp/tearDown fixture creation
+is required for this file.
+
+---
+
+## Files to Modify
+
+### 1. `src/Services/Catalog/CatalogServiceBuilder.php`
+
+Add, following the `productPropertySection()` pattern (no batch):
+
+```php
+public function storeProduct(): Catalog\StoreProduct\Service\StoreProduct
+{
+    if (!isset($this->serviceCache[__METHOD__])) {
+        $this->serviceCache[__METHOD__] = new Catalog\StoreProduct\Service\StoreProduct(
+            $this->core,
+            $this->log
+        );
+    }
+
+    return $this->serviceCache[__METHOD__];
+}
+```
+
+### 2. `phpunit.xml.dist`
+
+Add after the `integration_tests_scope_catalog_product_property_section` suite block
+(before `integration_tests_catalog_document`), around line 574:
+
+```xml
+<testsuite name="integration_tests_catalog_store_product">
+    <directory>./tests/Integration/Services/Catalog/StoreProduct/</directory>
+</testsuite>
+```
+
+### 3. `Makefile`
+
+Add after the `test-integration-scope-catalog-product-property-section` target, before the
+`test-integration-catalog-document` target:
+
+```makefile
+.PHONY: test-integration-catalog-store-product
+test-integration-catalog-store-product:
+	docker compose run --rm php-cli $(PHPUNIT) --testsuite integration_tests_catalog_store_product
+```
+
+Also add a doc-table row under the "Tests — integration (Catalog)" section in `docs/testing.md`
+(existing table already lists `catalog-price`, `catalog-document`, etc.):
+
+```markdown
+| `make test-integration-catalog-store-product` | Product stock by warehouse |
+```
+
+### 4. `CHANGELOG.md`
+
+Add under `## Unreleased` → `### Added`, as the first entry (top of the list):
+
+```markdown
+- Added service `Services\Catalog\StoreProduct` with support methods,
+  see [catalog.storeproduct.* methods](https://apidocs.bitrix24.com/api-reference/catalog/store-product/index.html) ([#584](https://github.com/bitrix24/b24phpsdk/issues/584)):
+    - `get` returns product stock information by record identifier
+    - `list` returns a list of product stock records by filter
+    - `getFields` returns the description of product stock fields
+```
+
+---
+
+## Deptrac compliance
+
+New code lives entirely in `Services\Catalog\StoreProduct\*` (a `Services` sub-namespace) and
+only imports from `Core` (`AbstractAnnotatedItem`, `AbstractResult`, `CoreInterface` via
+`AbstractService`, exceptions) and `Services\AbstractService`/`Services\Catalog` itself — same
+dependency shape as every existing Catalog service. No new deptrac violation is introduced; no
+`skip_violations` entry needed.
+
