Defined in:
lib/rubino/llm/adapter_factory.rb

Overview

Single seam where Lifecycle (and tests) decide which LLM adapter to instantiate. Keeps the “fake provider” branch out of RubyLLMAdapter so the real adapter stays focused on ruby_llm wiring.

Routing:

- explicit `provider: "fake"`        → FakeProvider
- model_id matches the "fake" regex  → FakeProvider
- everything else                    → RubyLLMAdapter

  # config default and let ProviderResolver interpret "auto" (including the
  # Bedrock-bearer override) in one place. RubyLLMAdapter then trusts the
