feedback-st-proactive-use-had-stale-brain-refs-both-workspaces

feedback_st_proactive_use.md in BOTH aj-ea and aj-workspace contained stale brain_record_decision and brain_submit_learning calls — a silent cross-workspace bug. This file is shared/synced pattern; any tool reference in feedback files propagates identically to both workspaces. When upgrading tool calls in feedback files, always check the same file in the other workspace.
