conductor(checkpoint): Phase 2 complete - Qwen via DashScope
Phase 2 of qwen_llama_grok_integration_20260606 ships Qwen support via the Alibaba Cloud DashScope native SDK. 10 of 11 state tasks done (t2.7 cancelled: no credentials_template.toml exists in the project; t2.9 was completed in Phase 1's initial registry population). Modules shipped: - src/qwen_adapter.py (31 lines): build_dashscope_tools() (OpenAI shape -> DashScope shape), classify_dashscope_error() (5 exception classes -> ProviderError kinds: auth/network/quota) - src/ai_client.py: state globals (_qwen_client, _qwen_history, _qwen_history_lock, _qwen_region), _ensure_qwen_client() (sets dashscope.base_http_api_url based on region: china vs international), _dashscope_call() + _dashscope_exception_from_response() + _extract_dashscope_tool_calls(), _send_qwen() (10-param signature matching _send_minimax), _list_qwen_models() - src/models.py: 'qwen' added to PROVIDERS (centralized; gui_2.py and app_controller.py import from this list) - src/cost_tracker.py: 7 Qwen pricing entries (regex-matched, USD per 1M tokens) Tests shipped: tests/test_qwen_provider.py (55 lines, 5 tests, all passing) Total new tests this phase: 5 Total tests in new modules: 30 (qwen + minimax + capabilities + openai_compatible + cost_tracker + no_top_level_sdk_imports) Verification: - 30/30 tests pass in batch - No regressions - 4/4 audit scripts pass (audit_main_thread_imports, audit_weak_types, check_test_toml_paths, audit_no_models_config_io) DashScope alignment (post-cleanup): - Uses dashscope.common.error.AuthenticationError (real class in 1.25.21) instead of the non-existent InvalidApiKey - Removed the InvalidApiKey -> AuthenticationError monkey-patch - TimeoutException -> network (not rate_limit) - ServiceUnavailableError -> network (not quota) - _ensure_qwen_client sets base_http_api_url per region (china vs international) per the latest DashScope API spec Deviations from the plan: - Test signature adapted from 12-param (plan) to 10-param (matching real _send_minimax) -- the plan's enable_tools / rag_engine params don't exist on _send_minimax - PROVIDERS change is at src/models.py:56 (centralized), not in gui_2.py and app_controller.py (which import from models) - t2.7 (credentials template) skipped: no template file exists; the user maintains their own credentials.toml directly Phase 3 (Grok + Llama) is now unblocked. Local LLM support lands in Phase 3 via Llama's Ollama backend (default base_url http://localhost:11434/v1).
