 Models - Pydantic proxies + DEFAULT_TOOL_CATEGORIES only.
 
-Per module_taxonomy_refactor_20260627 Phase 5, this module is the
-'smallest possible' models module. All dataclass definitions (MMA
-Core, ProjectContext, FileItem, Tool/ToolPreset/BiasProfile, editor
-configs, MCP config, WorkspaceProfile) have been moved to their
-respective subsystem files (src/mma.py, src/project.py, src/project_files.py,
-src/tool_presets.py, src/tool_bias.py, src/external_editor.py,
-src/mcp_client.py, src/workspace_manager.py, src/personas.py).
+Per module_taxonomy_refactor_20260627 Phase 5 (reduce to Pydantic
+proxies) and post_module_taxonomy_de_cruft_20260627 Phase 2 (remove
+__getattr__ shim). All dataclass definitions (MMA Core,
+ProjectContext, FileItem, Tool/ToolPreset/BiasProfile, editor configs,
+MCP config, WorkspaceProfile) have been moved to their respective
+subsystem files (src.mma, src.project, src.project_files,
+src.tool_presets, src.tool_bias, src.external_editor, src.mcp_client,
+src.workspace_manager, src.personas).
 
-The legacy 'from src.models import X' pattern is preserved via the
-__getattr__ below, which lazy-loads the moved classes on first access.
-New code should import directly from the subsystem files.
+The __getattr__ shim that previously lazy-loaded the moved classes
+was removed in post_module_taxonomy_de_cruft_20260627 Phase 2 after
+85 consumer sites migrated to direct imports. The remaining
+__getattr__ entries are:
+ - PROVIDERS (lazy load from src.ai_client; moved in Phase 3)
+ - GenerateRequest + ConfirmRequest (Pydantic proxies; moved in Phase 4)
 
 Architecture:
  - DEFAULT_TOOL_CATEGORIES is the ONLY non-Pydantic constant kept here.
    It groups the canonical tool list for the UI's category filter.
+   (Moved to src.ai_client in Phase 3.)
  - _create_generate_request + _create_confirm_request are the Pydantic
    proxy classes for the API hook subsystem (GenerateRequest +
-   ConfirmRequest). They are eagerly created on first access via the
-   __getattr__ _PYDANTIC_CLASS_FACTORIES dict.
- - __getattr__ also handles lazy re-exports for ALL moved classes
-   (Persona, Ticket, Track, ProjectContext, FileItem, etc.) and the
-   PROVIDERS constant from src.ai_client.
-
-See Also:
- - docs/guide_models.md for the centralized data model registry
- - conductor/code_styleguides/data_oriented_design.md for the type
-   promotion mandate
+   ConfirmRequest). (Moved to src.api_hooks in Phase 4.)
+ - The legacy 'Metadata = TrackMetadata' alias is preserved for
+   `from src.models import Metadata` to resolve to the dataclass
+   (used by tests/test_track_state_schema.py).
