…Boundary OpenClaw normalizes tool_result blocks into role:"user" messages with a tool_result content block. The sliceLastTurnsByUserBoundary function used to count every role:"user" message as a turn boundary, causing synthetic tool_result messages to fill the retention window and exclude actual user input from retained transcripts. This change adds a hasRealTextContent guard that skips user messages containing only tool_result blocks, ensuring only genuine user text is counted as turn boundaries for both retain and recall window slicing. Fixes: retained transcripts missing user input when tool calls are present
