ZddZ G d d ZdS )u MemoryManager — orchestrates the built-in memory provider plus at most
ONE external plugin memory provider.
Single integration point in run_agent.py. Replaces scattered per-backend
code with one manager that delegates to registered providers.
The BuiltinMemoryProvider is always registered first and cannot be removed.
Only ONE external (non-builtin) provider is allowed at a time — attempting
to register a second external provider is rejected with a warning. This
prevents tool schema bloat and conflicting memory backends.
Usage in run_agent.py:
self._memory_manager = MemoryManager()
self._memory_manager.add_provider(BuiltinMemoryProvider(...))
# Only ONE of these:
self._memory_manager.add_provider(plugin_provider)
# System prompt
prompt_parts.append(self._memory_manager.build_system_prompt())
# Pre-turn
context = self._memory_manager.prefetch_all(user_message)
# Post-turn
self._memory_manager.sync_all(user_msg, assistant_response)
self._memory_manager.queue_prefetch_all(user_msg)
