Detailed Description

AdapterManager — LoRA adapter lifecycle and hot-swap.

Responsibilities

• Load/unload LoRA adapters against a base model
• Activate/deactivate adapters on an inference context
• Track adapter states (COLD/WARM/HOT)
• Enforce single-HOT constraint per context
• Provide adapter metadata for routing

Thread safety

• State queries require the class mutex (AdapterEntry::state)
• load/unload/swap acquire adapter_mutex_
• Swap operations coordinate with InferenceBackend transition_mutex_ via the orchestrator (AdapterManager does NOT lock the backend)

Ownership

Owned by ModelOrchestrator. One AdapterManager per engine instance.

Version
