ProcessorRegistry 

Purpose 

Resolves assistant pipeline processors by identifier.

Required interface 

Madj2k\AiCore\Assistant\Pipeline\Processor\ProcessorInterface

Service registration 

Register implementations through a service tag:

services:
  Vendor\Extension\Assistant\Pipeline\Processor\MyProcessor:
    tags:
      - name: 'aiassistant.assistant.pipeline.processor'

Identifier 

The implementation should expose a stable identifier. Configuration records use that identifier to resolve the implementation at runtime.

Implementation rules 

• Keep services stateless where possible.
• Read credentials and runtime options from configuration records.
• Throw meaningful exceptions for invalid configuration.
• Return core DTOs rather than provider-specific arrays where interfaces define DTOs.

Processor type matching 

The registry resolves processors by processor_identifier. The pipeline step type is still important and should always be one of the values defined by Madj2k\AiCore\Assistant\Enum\AssistantPipelineProcessorType.

Processor implementations should use this enum when implementing supports() or equivalent matching logic. Static SQL and default configurations should also use enum values for the type column.
