AitherADK v2.6.4
Deep Research Agent + aither-adk 2.6.4.
Fix: loop-guard nudges no longer corrupt the tool-call message history. When the ReAct loop emitted several tool calls in one turn and the loop guard fired (WARN/BLOCK/CIRCUIT_BREAK) on one — e.g. after crossing the 15-call threshold during a long research run — it spliced a system message between the tool results, which DeepSeek (and strict vLLM templates) reject with 400 ... insufficient tool messages following tool_calls message, aborting the turn. Guidance is now folded into each tool result and standalone steering deferred to after the batch.
Deep Research Studio also streams Sources live and keeps them on a failed/partial turn.
