Workflow Visualization with Time-Travel Controls

Module

Web

Status

IMPLEMENTED

Description

DAG-based workflow visualizer with time-travel debugging controls. Users can step forward/backward through workflow execution states, inspect step details at each point in time, view execution logs, and interactively debug release workflows. The time-travel service manages historical state snapshots. (Merged with Workflow Visualization UI Module from Phase 2 Web section.)

E2E Test Plan

Setup:
- Log in with a user that has appropriate permissions
- Navigate to /release-orchestrator
- Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
Core verification:
- Verify the visualization renders correctly with sample data
- Verify interactive elements (hover tooltips, click-to-drill-down) work
- Verify the visualization handles empty/minimal data gracefully
Edge cases:
- Verify graceful handling when backend API is unavailable (error state)
- Verify responsive layout at different viewport sizes
- Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
