Navigate the developer docs

For: Platform Builder

Part of: docs-ia-restructure

Steps

• Scan (browser) — sidebar top-to-bottom: orient via Getting Started → Guides → Features by area → Project Management → Reference → Architecture → Source Map → Exports
• Open (browser) — the MCP Tools area group and find usm_update_system without scrolling past 38 unrelated pages
• Verify (browser) — each group title says what it contains; no group is named after an arbitrary first item

How this is verified

• sidebar JSON contains no group nested inside another group's items
• top-level groups match the intended dev order and names
• no label contains a doubled area prefix; no duplicate 'Overview' labels
