From 9bba317d7281cde6f1faf15d940b21dced938816 Mon Sep 17 00:00:00 2001 From: Ed_ Date: Fri, 19 Jun 2026 19:10:48 -0400 Subject: [PATCH] refactor(app_controller): migrate L242 (RAG) + L256 (symbols) to Result helpers (Phase 7) Tasks 7.2 + 7.3: Replace inline try/except with sys.stderr.write in _api_generate with calls to the Phase 6 _rag_search_result and _symbol_resolution_result helpers. Errors are now carried in self._last_request_errors instead of being logged silently. Per Phase 7 spec 22.5.1 + 22.5.2: - L242 (RAG): calls controller._rag_search_result(user_msg) - L256 (symbols): calls controller._symbol_resolution_result(user_msg, file_items) - On error: append to controller._last_request_errors (with op name) - On error: stderr.write is the visible-but-incomplete drain (full drain = sub-track 4 GUI) The audit heuristic at scripts/audit_exception_handling.py:393-397 still classifies these as BOUNDARY_FASTAPI (over-applied); this is addressed by Task 7.6 (audit heuristic tightening).
