+# Phase 16 — Native MySQL Diagnostics
+
+Adds five read-only Administration → Performance screens:
+
+- **Slow Query Analysis:** `performance_schema.events_statements_summary_by_digest` sorted by cumulative execution time, with counts, rows examined, and first/last seen timestamps. Times are raw picoseconds, **not** milliseconds.
+- **Table I/O Hotspots:** `performance_schema.table_io_waits_summary_by_table` with read/write counts and timings.
+- **InnoDB Metrics:** selected `SHOW GLOBAL STATUS` buffer-pool, I/O, lock, and row counters.
+- **InnoDB Lock Waits:** current edges in `performance_schema.data_lock_waits`.
+- **Connection Statistics:** connection, abort, thread, and query counters.
+
+All screens reuse the existing searchable grid, manual refresh, and optional five-second auto-refresh. SQL is read-only. Some screens require MySQL 8.0+ and enabled Performance Schema instrumentation/privileges; errors are displayed in the existing administration error view. The digest and table I/O summaries are cumulative and may be reset by server restarts or instrumentation changes. This phase does **not** enable slow-query logging or change server configuration.
+
+## Validation
+
+Source inspection and ZIP integrity check performed. **Not compiled with Xcode or tested on a live MySQL server.** Test on a nonproduction MySQL 8.0+ instance first.
