From a83a7f8765298d1a4b0ecb94daf0e04f23d571a2 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Thu, 19 Mar 2026 22:11:08 +0000 Subject: [PATCH 1/4] =?UTF-8?q?=E2=9A=A1=20Bolt:=20Use=20persistent=20SQLi?= =?UTF-8?q?te=20connection?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Previously, the `DatabaseBase` class recreated the `sqlite3` connection for every check (`contains()`), insertion (`add()`), deletion (`remove()`), and retrieval (`all()`).
