+// Those three things — `memory-driver.json`, `flush()`, the autosave timer —

+// leaves nothing on the host and a restart starts empty — so the block is
+// rewritten against sqlite `:memory:` rather than deleted (deleting it would

-// leaves nothing behind and does not outlive its kernel — without a timing race
-// and without depending on run-to-run state.
+// Under `:memory:` the property is asserted more directly than before: a fresh
+// pool has no `ext_note` TABLE at all, not merely no rows — the one thing a
+// reloaded snapshot could never look like. The filesystem half is unchanged and
+// still load-bearing: `filename: ':memory:'` is one config typo away from a
+// relative file path, and that typo is exactly what #4083 was.
