Audit & Governance: Change history

The Change history view in Audit & Governance now shows who changed what across your team's shared spaces — covering both memory and file activity — filterable by person, event type, space, and date range, and exportable as CSV. Rows for deleted users still show who made the change, pulled from the audit trail's denormalized metadata. Activities that came through the MCP server (Claude and other agents) are labelled "via Claude" in the Who column.
