…ranches Add detailed analysis document covering: - 15 edge cases handled correctly in current implementation - 8 missing edge cases that need consideration - 6 missing features compared to BPMN/UML standards - Prioritized recommendations with effort estimates - Industry comparison (BPMN 2.0, UML 2.5 sequence diagrams) - Test scenarios for validation gaps - Refactoring suggestions for modularity Key findings: - Overall Grade: A- (production-ready with minor gaps) - Critical fixes needed: empty path validation, nesting depth limit - Future features: guard conditions, loop fragments - No suitable packages found to simplify the logic References research on BPMN engines, UML tools, and workflow platforms to identify common pitfalls and best practices.
Provides in-depth analysis of: ## Part 1: 8 Missing Edge Cases (Prioritized by Severity) 🔴 CRITICAL: 1. Empty paths not validated - 10 min fix needed 2. Unbounded nesting depth - 30 min fix needed⚠️ IMPORTANT: 3. Mixed anonymous/named paths - 15 min hint needed 4. Series in nested branches - test gap, 20 min to verify 5. Circular navigateTo - defer to view graph validation 6. Unwieldy step IDs - fixed by #2 🔵 LOW: 7. Both __parallel and paths populated - data integrity edge case 8. Missing test coverage - 2 hours to add all tests Total effort for critical fixes: ~4 hours ## Part 2: 12 Edge Case Comparisons (Industry vs. Implementation) Compares against BPMN engines (Flowable, Camunda), UML tools (IBM, Visual Paradigm), and workflow platforms (AWS Step Functions, Azure Logic Apps, n8n, Dify, Google Cloud Workflows, LangGraph). Key findings: - ✅ 10/12 industry issues DON'T apply (different execution model) -⚠️ 2/12 need attention (nesting depth, empty branches) - Static declarative model elegantly avoids runtime execution problems Verdict: Smart design choices prioritizing simplicity and determinism.

Pull Request Overview
This PR adds comprehensive documentation analyzing edge cases and industry comparisons for LikeC4's parallel and alternate branch implementation in dynamic views. The analysis examines the implementation against common issues in BPMN, UML sequence diagrams, and workflow engines.
Key Changes
- Detailed analysis of 8 missing edge cases with severity classifications and recommended fixes
- Comparison of 12 industry-standard workflow problems against the current implementation
- Prioritized recommendations for improvements including validation rules and test coverage gaps

[nitpick] Consider adding 'the' before 'runtime' for clarity: 'but the runtime doesn't enforce it'.

The citation 'Medium article on LangGraph' is vague. Consider providing a more specific reference (e.g., article title, author, or URL) for better traceability and credibility.

The citation 'IBM Docs' is too generic. Consider providing a specific document title, section, or URL for the IBM documentation being referenced.
