"""DataSourceABCImpl — thin combiner that composes all pipeline mixins.

The 1797-line monolith has been split into focused mixin classes under
main_core/mixins/.  This module now only:
  1. Re-exports the public enums that other code may import from here
  2. Defines the combiner class that inherits from all mixins

Every mapper subclass still does exactly:
    from main_core.data_source_abc_impl import DataSourceABCImpl
    class MyMapper(DataSourceABCImpl): ...

The MRO (left-to-right mixin order) ensures mapper overrides are always
found first and that all abstract methods from DataSourceABC are satisfied.

Mixin responsibilities:
  StateMixin               — __init__, run-state reset, health-check predicates
  FetchMixin               — HTTP / local fetch, multi-fetch, metadata checks
  FileReadTransformMixin   — read_file_content, format auto-detection, transform
  TableManagementMixin     — create/clone/index ETL tables
  EtlOperationsMixin       — staging → enrichment → mapping operations
  RunPipelineMixin         — run, execute, thread-pool file processing, create_job
  MetadataTrackingMixin    — run-lifecycle metadata persistence
  TimingReportingMixin     — stage timing and ASCII/CSV reports
  LifecycleHooksMixin      — overridable hooks (load, filters, before/after file)
  DataSourceABC            — abstract contracts (unchanged)

    Inherits all behaviour from the mixins above.  Mapper subclasses extend
    this class and override only the methods they need (read_file_content,

    mapping_db_query, enrichment_db_query, staging_db_query, etc.).

    See main_core/mixins/ for full documentation of each method.
