# Singleton Visualizer

Use LikeC4 for reviewed architecture. Use an HTML comp only for a human review
that cannot be understood as a short document.

When Jerami's review would exceed 500 words, use a dated interactive HTML comp
on the Decision Maps page. Keep the written entry point short. The map must
reduce reading load through sequence, hierarchy, or disclosure.

Read `references/visual-contract.md` first.

```text
Next/Vercel       = active-week review dashboard
Supabase          = queryable facts and routing registry
```

- Show 5-9 meaningful nodes.
- Use current owner names.
- Keep edge labels short.
- Mark ambiguity instead of inventing a system.
- Validate LikeC4 source and generated output before calling the map complete.
