Tail-end of Phase 2: - Migrate ~70 remaining test sites off AppConfig.current(): drop dead monkey-patches (production no longer calls current), hoist the mocked config into a local variable and pass it explicitly. Verified with `grep -rn 'AppConfig\.current' backend/tests` → empty. - Delete the AppConfig.current() classmethod entirely. The transitional raise-only shim is no longer needed now that no test references it. - Update docs: plan marked shipped (P2-6..P2-10 in commit 84dccef2); backend/CLAUDE.md Config Lifecycle rewritten to describe the explicit-parameter design; gateway/deps.py docstrings no longer point at the removed current() surface. AppConfig is now a pure Pydantic value object. Every consumer holds its own captured instance — Gateway (app.state.config via Depends(get_config)), DeerFlowClient (self._app_config), agent runtime (DeerFlowContext.app_config), LangGraph Server bootstrap (AppConfig.from_file() inside make_lead_agent). 2337 non-e2e tests pass.
