From 3459f821c598860a3921f65c2209ccaa78c9630e Mon Sep 17 00:00:00 2001 From: HAL9000 Date: Wed, 13 May 2026 05:18:35 +0000 Subject: [PATCH 1/3] fix(events): add close() method to ReactiveEventBus to complete RxPY subject Add _closed flag and close() method to ReactiveEventBus to complete the RxPY Subject, preventing subscriber resource leaks. close() is idempotent and raises RuntimeError when called on a closed bus. Also adds: - emit() guard against post-close calls (RuntimeError) - __enter__/__exit__ context manager protocol for automatic cleanup - BDD scenarios in event_bus.feature and TDD tests in
