From 9792449157e76404079f3ef43322918f884454c0 Mon Sep 17 00:00:00 2001 From: GlyphRunner System Date: Wed, 20 May 2026 18:11:25 -0400 Subject: [PATCH] Implement GlyphOS Event System MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add lightweight, in-process event bus with Cognitive Kernel integration: New Components: - glyphos/events.py: EventBus class + functional API * EventBus: publish/subscribe pattern with history * Event type definitions (EventType literal) * Singleton: get_event_bus(), emit(), on() * History filtering and limits * Graceful handler error handling - tests/test_events.py: Comprehensive test suite (16 tests, 100% pass) * EventBus subscription/publishing/history * Global singleton behavior * Functional API (on, emit, get_event_bus) * Kernel integration tests * Cognition event emission tests Modified: - glyphos/cognitive_kernel.py: Event emissions at key points * kernel.warmup.completed: After warmup() completes * cognition.started: At start of execute_gx() * cognition.completed: After execute_gx() completes * glyph.resonance.updated: When glyph resonance present - glyphos/__init__.py: Export events module Test Results: - Registry tests: 12/12 ✅ - Bridge tests: 10/10 ✅ - Kernel tests: 8/8 ✅ - Event system tests: 16/16 ✅ (NEW) - Integration tests: 6/6 ✅ - Total: 52/52 ✅ No breaking changes - all 36 existing tests still pass. --- glyphos/__init__.py | 21 +- glyphos/cognitive_kernel.py | 44 +++ glyphos/events.py | 183 ++++++++++++ tests/test_events.py | 561 ++++++++++++++++++++++++++++++++++++ 4 files
