+
+### Fixed
+- **NULL agent values in query metrics eliminated**: `recordMetrics()` now auto-detects agent via `getAgentIdentity()` when callers don't provide it. Previously 15 of 18 tools omitted the agent field, resulting in NULL values in `gitmem_query_metrics`.
+
+### Performance
+- **session_start ~200-300ms faster**: Sessions and threads queries now run in parallel (`Promise.all`) instead of sequentially inside `loadLastSession`.
+- **session_close transcript upload no longer blocks**: Transcript save moved from blocking `await` to fire-and-forget via effect tracker. Removes 500-5000ms variable cost from `latency_ms`. Claude session ID extraction remains synchronous.
