 **Description:** `EnqueueAsync` is declared `async`-shaped (`Task EnqueueAsync(...)`) and the `IAlarmHistorianSink` contract explicitly states "the sink MUST NOT block the emitting thread … `EnqueueAsync` returns as soon as the queue row is committed." But the implementation does fully synchronous, blocking SQLite I/O (`conn.Open()`, `EnforceCapacity`, `cmd.ExecuteNonQuery()`) on the caller's thread and only then returns `Task.CompletedTask`. Under SQLite write contention with the drain worker this blocks the alarm-emitting thread for the full lock-wait. The same synchronous-work-behind-an-async-or-status-API pattern applies to `GetStatus` (called from the Admin UI / `/healthz` request thread) and `RetryDeadLettered`. The `cancellationToken` parameter of `EnqueueAsync` is accepted and ignored.
 
 **Recommendation:** Either make the I/O genuinely asynchronous (`await conn.OpenAsync(ct)`, `await cmd.ExecuteNonQueryAsync(ct)` — `Microsoft.Data.Sqlite` supports the async surface), or change `EnqueueAsync` to an in-memory hand-off (e.g. a `Channel`) drained by a background writer so the emitting thread truly never touches the database. At minimum honor the `cancellationToken` parameter.
 
-**Resolution:** _(open)_
+**Resolution:** Resolved 2026-05-22 — `EnqueueAsync` now uses `OpenAsync` / `ExecuteNonQueryAsync` / `ExecuteScalarAsync` throughout (capacity check included); `ApplyPragmasAsync` handles the WAL/busy-timeout PRAGMA on the async path; `cancellationToken` is threaded through every await so cancellation is honoured.
