Application Layer Bundle Laravel Package

Added

• Repository LICENSE file (MIT) at the repo root, with the contributor copyright line Copyright (c) 2026 Elrise.IO Alexk <[email protected]> (AR-015). Packagist and most open-source tooling require this file by name (LICENSE, LICENSE.md, or LICENSE.txt); it ships verbatim alongside composer.json's license: MIT declaration.
• Packagist readiness metadata on composer.json: keywords (symfony, symfony-bundle, cqrs, ddd, application-layer, dto, messenger) for faceted search (AR-010).
• Packagist UI metadata on composer.json: homepage (GitHub repo) and a support block with issues, source, and docs links (AR-014).
• composer.json carries version: 1.0.0 removed in favour of git tags, plus extra.branch-alias.dev-main = 1.x-dev so composer require elriseio/application-layer-bundle:dev-main resolves before the first tag is published (AR-014).
• composer.json scripts block now exposes cs:check (php-cs-fixer fix --dry-run --diff), test (phpunit), and check ([[@cs](https://github.com/cs):check, [@test](https://github.com/test)]) alongside the existing cs:fix (AR-014).
• CQRS-shaped contracts: CommandHandlerInterface (mutating state) and QueryHandlerInterface (read-only), each registered through its own tagged service locator (app_layer.command_handler and app_layer.query_handler).
• DataProcessorInterface for DTO-less entry points (projections, lookup tables, computed reads), registered via the app_layer.data_processor tag.
• DtoRequestHandler with two explicit entry points: dispatchCommand() (runs sanitize → convert → resolve → invoke → optional queue dispatch) and dispatchQuery() (runs convert → resolve → invoke; sanitization is skipped because read-side input is not mutated).
• DefaultRequestToDtoConverter that extracts the payload from a Symfony Request (JSON body, or merged query + form) and hands it to a DtoDeserializerInterface.
• SymfonyDtoDeserializer with a built-in selfDenormalizer that handles two DTO shapes without external dependencies:
  • constructor DTOs (including readonly promoted properties) — delegates to Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
  • property-only DTOs — instantiates via ReflectionClass::newInstanceWithoutConstructor() and writes fields via reflection.
• MessengerQueueDispatcher (auto-wired when symfony/messenger is installed) and NullQueueDispatcher (fallback when it is not). Both implement DtoQueueDispatcherInterface and are bound conditionally in AppLayerProcessorExtension.
• RequestException with a structured details array for diagnostic context (denormalization failures, handler-resolution failures, type mismatches).
• RequestSanitizerInterface (optional, commands only) with a default no-op RequestSanitizer implementation.
• Autoconfigure-tagged contract interfaces so consumer handlers and processors require no service declarations.

Changed

• The single pre-1.0 RequestHandlerInterface is split into CommandHandlerInterface and QueryHandlerInterface. Each carries #[AutoconfigureTag(...)] and is resolved through its own #[TaggedLocator(...)] on DtoRequestHandler.
• The trait-map dispatch (RequestHandlerTraitMapProviderInterface and the default DefaultRequestHandlerTraitMapProvider) is removed. The old RequestHandlerInterface is gone.
• The DataProcessorPass compiler pass is removed in favour of the #[TaggedLocator('app_layer.data_processor')] attribute on DataProcessor::__construct().
• DtoRequestHandler::handle() is replaced by DtoRequestHandler::dispatchCommand() and DtoRequestHandler::dispatchQuery(). The two methods are explicit about which steps of the pipeline they run.
• The property-only DTO deserialization path no longer calls ReflectionProperty::setAccessible(true). PHP 8.1+ semantics allow direct assignment to typed properties regardless of visibility, so the deprecation warning is gone.
• The README is rewritten in English with a CQRS-shaped pipeline diagram and CQRS-flavoured examples (CreateOrderHandler, ListOrdersHandler).

Removed

• RequestHandlerInterface and the trait-map dispatch layer (RequestHandlerTraitMapProviderInterface, DefaultRequestHandlerTraitMapProvider).
• The DataProcessorPass compiler pass.
• ReflectionProperty::setAccessible(true) from the property-only DTO path.
