# Compatibility Removal Plan

This document tracks the remaining migration-only surfaces that still exist
after the move to split-first development.

## Migration-only Surfaces

None currently remain as dedicated compatibility wrappers.

## Completed Removals

### `backend.app`

- Removed after compatibility startup switched to
  `backend.apps.combined_service:app` directly.

### `shared.client.AgentServiceClient`

- Removed after split-aware clients became the default import surface.
- Replacement:
  - `ControlPlaneClient`
  - `RuntimeServiceClient`
  - `TradingServiceClient`
  - `NewsServiceClient`

### `backend.apps.combined_service`

- Removed after split-service mode became the only supported dev startup path.
