+## v8.0.11 — 2026-07-02 (no script shape can hang on brainy's internals)
+
+Completes v8.0.10's exit fix for every operation class. Two further mechanisms found and fixed:
+the `beforeExit` auto-flush hook looped forever on any script that never reaches `close()` (Node
+re-emits `beforeExit` after each event-loop drain and the async flush schedules new work — it now
+self-deregisters before its single flush, which still lands your buffered data before exit), and
+every background-maintenance interval (graph auto-flush, LSM compaction, metadata write-buffer,
+VFS/path-cache maintenance, statistics debounce) is now unref'd at creation. Verified against the
+published package: an `add + relate` script exits cleanly both with `close()` (~0.5 s) and with no
+teardown at all — with the data confirmed durable on reopen. A per-operation-class sweep test now
+asserts no ref'd timer survives `close()`, so this bug class stays closed.

 ## v8.0.10 — 2026-07-02 (a bare script exits cleanly after `close()`)
 
 A minimal `init → add → close` script used to hang forever after `close()` returned — brainy held
