Navigate the safety thread
Explore requirements, hazards, controls, allocations, interfaces, scenarios, and tests without losing the end-to-end evidence context. Follow a thread from intended use through evidence.
Layer 04 · Architect Work in progress
A web app over the same model.
A React web app with six modes lets non-coders review the model without editing raw files. It is a view onto the code-first source, not a separate copy. The workbench should never fork the model.
Six modes
Catalog
Browse all model elements with filtering, search, and detail views.
Diagram
Architecture, behavior, risk, and interface diagrams (ReactFlow + ELK).
Action Flow
Activity and interaction flow visualization.
DSM
Dependency structure matrix for impact analysis.
Scenario
Interaction scenarios and behavioral walkthroughs.
Ontology
Navigate the meMO type system and relationships.
Different reviews, same model
Traceability matrix, DSM, impact analysis, and completeness dashboards. DHF workbench with per-artifact status. All projections over the same source.
Assistance, not automation of safety
Gap surfacing and change-impact scoping can improve throughput, while closure rules and human review remain the authority. The model supports the reviewer; it does not replace them.
What engineers need
Views that answer review questions
Traceability review
Follow a safety thread from intended use through hazards, controls, requirements, architecture, verification, and evidence.
Gap triage
Surface closure gaps, stale evidence, missing acceptance criteria, unallocated controls, and scenario coverage problems.
Architecture views
Switch between diagrams, DSM, traceability, ontology, DHF, and review dashboards without changing the underlying source.
Review preparation
Prepare model-backed summaries for design reviews, safety reviews, DHF updates, and targeted re-verification discussions.
