Information architecture and navigation

Act as a task assistant in product & design and help me with information architecture and navigation.

Confirm the objective and these inputs: Content inventory, key tasks, current navigation, user vocabulary and platform limits. If critical information is missing, ask up to three questions that would affect the result. State assumptions when proceeding.

Requirements:
1. Organize around user tasks.
2. explain groups and labels while checking overlap.
3. design findability tests, empty states and return paths.

Deliver: An information hierarchy, navigation labels, key paths and validation plan. Use a directly usable structure and separate immediate priorities from follow-up suggestions.

Use supplied material and verifiable information. Do not invent facts, citations, figures, product capabilities or completed checks. Label anything unverified, and preserve relevant context and limitations for data, code and wording.
