+ *
+ * taiga/events/middleware.py stores the X-Session-ID header in a threading.local.
+ * Under thread-pool workers (gunicorn sync workers, celery) the same OS thread can
+ * serve multiple requests. If a background task or a signal handler fires after the
+ * response is returned but before process_response clears the local, the session_id
+ * bleeds into an unrelated request context.
+ *
+ * Fix: replace threading.local with contextvars.ContextVar — each task/coroutine gets
+ * its own copy automatically.
+ *
+ * This test models the defect with ThreadLocal<String> (Java analog) vs
+ * per-invocation context passing and demonstrates cross-thread contamination.
