Week 4 - Event Infrastructure: - Create SpaceEventType enum with 18 event types covering space lifecycle, document operations, variables, references, rendering, sync, and cache - Create SpaceEvent dataclass with serialization/deserialization - Create EventBus with sync/async handler support, priority ordering, global handlers, and optional event history - Add event factory functions for common events Week 5 - Event Integration: - Wire EventBus into SpaceService as optional dependency - Emit events for all space operations: - SPACE_CREATED, SPACE_UPDATED, SPACE_DELETED, SPACE_ACTIVATED, SPACE_ARCHIVED - DOCUMENT_ADDED, DOCUMENT_REMOVED, DOCUMENT_MOVED, DOCUMENT_CONTENT_CHANGED - VARIABLE_SET, VARIABLE_DELETED - Create integration tests for event propagation patterns Test coverage: 187 tests total - 43 unit tests for event system - 20 integration tests for event propagation - 124 existing tests continue to pass Capabilities delivered: - CAP-010: SpaceEvent base with type, payload, timestamp - CAP-011: EventBus with in-process publish/subscribe - CAP-012: Event handlers registry with priority support - CAP-013: Change detection via content hash comparison Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Event system for Information Spaces.
|
|
|
|
This package provides event-driven architecture for space operations:
|
|
- SpaceEvent: Event dataclass with type, payload, timestamp
|
|
- SpaceEventType: Enum of all event types
|
|
- EventBus: In-process publish/subscribe for space events
|
|
- Event factory functions for common events
|
|
|
|
Events emitted:
|
|
- Space lifecycle: SPACE_CREATED, SPACE_UPDATED, SPACE_DELETED, SPACE_ACTIVATED, SPACE_ARCHIVED
|
|
- Document: DOCUMENT_ADDED, DOCUMENT_UPDATED, DOCUMENT_REMOVED, DOCUMENT_MOVED, DOCUMENT_CONTENT_CHANGED
|
|
- Variable: VARIABLE_SET, VARIABLE_DELETED
|
|
- Reference: REFERENCE_ADDED, REFERENCE_CLEARED
|
|
- Rendering: RENDER_STARTED, RENDER_COMPLETED, RENDER_FAILED
|
|
- Sync: SYNC_STARTED, SYNC_COMPLETED, SYNC_CONFLICT
|
|
- Cache: CACHE_INVALIDATED
