"copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Sat, 7 Mar 2026 05:16:02 +0000 Subject: [PATCH 3/3] fix: address all PR review feedback for SelfModificationEngine - Add asyncio.Lock for concurrent safety on all state mutations - Add history retention cap (max 1000 records) with eviction - Add ProposalNotFoundError/ProposalStateError for 404 vs 409 mapping - Validate parameters is dict, non-empty component/weight, non-empty module name - Add session-token auth (X-API-Token header, GODELOS_API_TOKEN env var) - Respect knowledge_type and limit in /api/knowledge merge - Log ImportError in backend/core/__init__.py - Define self_modification_engine=None at module scope - Fix test fixture with getattr; disable lifespan in transport - Add 11 new tests (28 total): auth, 409 conflict, validation edge cases Co-authored-by: Steake <530040+Steake@users.noreply.github.com> --- backend/core/__init__.py | 7 +- backend/core/self_modification_engine.py | 186
