Extract _get_api_key() and _create_provider_instance() as a single internal factory that handles all provider types, including MOCK. Both create_llm() and create_ai_provider() now delegate to _create_provider_instance(), eliminating the duplicated if/elif provider-switching chains and the divergence between the two code paths. Adding a new provider now requires touching exactly one place. Key changes: - New _get_api_key(provider_type) consolidates API key lookup and validation that was previously duplicated across create_llm(), _create_provider_llm(), and every branch of create_ai_provider(). - New _create_provider_instance() is the unified raw-LLM factory, replacing _create_provider_llm() and the specialised adapter constructors in create_ai_provider(). MOCK is now handled here via FakeListLLM. - create_ai_provider() wraps all providers uniformly in LangChainChatProvider instead of using specialised adapters (OpenAIChatProvider, AnthropicChatProvider, GoogleChatProvider, OpenRouterChatProvider) for the four primary providers. - create_llm() drops its own API key validation block; validation now happens inside _create_provider_instance() via _get_api_key(). - All BDD scenarios updated: _create_provider_llm references become _create_provider_instance, and provider-type assertions on create_ai_provider results are updated to LangChainChatProvider. Review fixes (Cycle 2): - Add _coerce_env_bool() for consistent boolean env-var coercion in CLEVERAGENTS_ALLOW_MOCK_PROVIDER checks. - Introduce _ApiKeyMissing sentinel to distinguish 'not provided' from None in provider configuration. - Set MOCK supports_streaming=False in DEFAULT_CAPABILITIES to align with FakeListLLM semantics. - Make MOCK is_configured conditional on CLEVERAGENTS_ALLOW_MOCK_PROVIDER. - Use FakeListLLM(responses=['mock response'] * 10) to prevent IndexError in multi-step workflows. - Strip max_retries from kwargs before passing to LangChain constructors. - Extract _resolve_provider_type() helper shared by create_llm() and create_ai_provider() to reduce duplication and improve readability. - Ensure __api_key_sentinel flows through factory_kwargs even when api_key is None, avoiding double _get_api_key() calls. - Add CHANGELOG env-var documentation and providers.md env-var table. - Resolve template DB lock issues by persisting in-memory SQLite via VACUUM INTO instead of direct file creation on tmpfs.
