Sources and dual Apache-2.0/MIT licenses come from the published sqlx-sqlite 0.9.0 crate, revision 003b698e99e024f3621b8043a2426fde5b741171. upstream.json records each original file hash. Published license files are relative references; their full texts are included here from the same pinned repository revision, with URLs and hashes in license_sources. The normalized published manifest and production dependencies are unchanged. Three upstream documentation lines in connection/deserialize.rs have trailing whitespace removed for the source hooks; behavior is unchanged.
The existing SqliteConnection::establish is public, and existing PRAGMA/collation configuration is moved into configure(&mut self, options). Ordinary ConnectOptions::connect still delegates to the same steps. Maka's independent SQL owner retains the actual connection between establishment and configuration, waits for real close on startup failure, and keeps its original authority on unconfirmed cleanup. No second SQL worker, connection registry or error-string classification is added. WorkerCrashed during establishment is explicitly unconfirmed.
中文：公开原有 establish，将 PRAGMA/collation 配置移为借用实际连接的 configure。普通 connect 保持原语义；Maka 原 SQL owner 先持有真实连接，再进行配置，启动错误须等真实关闭，无法确认时保留原 authority。没有新增 SQL owner 或执行注册表。
run_on_worker submits one synchronous callback to the existing worker under its exclusive handle guard. The callback borrows the handle and returns owned data; its Rust panic resumes on the awaiting task. SQLx still owns transaction bookkeeping and physical close. Accepted callbacks continue if their observer disappears; abandoning a callback future alone does not guarantee rollback.
中文：run_on_worker 将同步回调交给原工作线程，在原独占 guard 内借用句柄并返回自有数据；回调的 Rust panic 在等待方继续展开。事务记账和实际关闭仍由 SQLx 管理。等待方消失不取消已受理回调，单独丢弃回调 future 不保证回滚。
run_with_connection uses that same callback command and exclusive worker guard to borrow a SqliteWorkerConnection. Its Executor implementation drives the existing ExecuteIter, row decoders and bounded Statements cache directly; query futures and streams are immediately ready and stop at the first error. The raw-handle callback delegates to this same entry point. Neither callback may control transactions or retain raw handles. Maka polls a bounded worker query once, failing closed if it unexpectedly yields, and leaves commit/rollback and cache maintenance with the original owner job.
中文：run_with_connection 沿用原回调命令和独占 guard，直接借用 SQLx 原有执行器与有界语句缓存；查询 future/stream 立即就绪，首个错误终止执行。原句柄回调委托给同一入口。事务、实际关闭和查询后的维护仍归原 owner；没有新增连接、运行时或持久缓存。
