# Phase 17 — SQL Editor Productivity

- Added persisted query execution history (latest 200 statements), including timestamp, connection, schema, success/failure, and error details. Schema-list refreshes are not recorded.
- Added History panel with filtering, reopen in a new tab, and clear history.
- Added a persistent saved SQL query library, with save, filter, open, and delete.
- Added AppKit SQL keyword completion via NSTextViewDelegate's standard completion interface (typically Esc or Option-Esc depending on macOS key bindings). Completions are keyword-based, not live schema-aware.
- Preserved the existing SQL syntax highlighting and query tab handling.

## Caveats

History and saved SQL are stored in local UserDefaults and may contain sensitive SQL text; avoid executing statements containing literal secrets if local history retention is a concern. Results remain subject to the existing protocol row cap. This phase has not been built in Xcode or tested against a live server.
