# Glossary

> Key Terms across Lumafield  

Lumafield's platform consists of scanners, software, automations and more. Use this glossary to familizarize yourself with some of the key terms. Entries are grouped by topic and alphabetized within each section.

## Resource Management & Deployment

<Card title="Active storage (TB)" iconType="regular">
  Writable tier for projects. Editors can create new analyses and data. New scans initially land as Active projects.
</Card>

<Card title="Automatic Read‑Only Migration" iconType="regular">
  A manager‑controlled setting. When enabled, projects exceeding Inactive TB migrate to Read‑Only in least‑recently‑accessed order. Does not affect Active → Inactive migration (which always occurs for Pro/Enterprise).
</Card>

<Card title="GovCloud" iconType="regular">
  A deployment environment with the same Resource Management concepts as Cloud (TB budgets, annual Tokens), subject to GovCloud operational requirements.
</Card>

<Card title="Inactive storage (TB)" iconType="regular">
  Delayed‑access tier optimized for capacity. Read access is available; to write again, move the project back to Active (may take time). Active → Inactive migration occurs when the Active TB budget is exceeded.
</Card>

<Card title="Pinned project" iconType="regular">
  An Active project explicitly kept in the Active tier. Pinned projects are excluded from automatic migration while pinned.
</Card>

<Card title="Pricing tier" iconType="regular">
  Controls visibility and behavior of usage features. Legacy shows no usage UI; Pro/Enterprise enables Resource Management.
</Card>

<Card title="Project Limit Mode (Auto‑Archive)" iconType="regular">
  Default behavior for Pro/Enterprise organizations to automatically migrate projects between tiers when budgets are exceeded.
</Card>

<Card title="Read‑Only project" iconType="regular">
  View‑only state: analyses, data objects, meshes, bookmarks remain available to inspect and share, but no new data can be authored. On cloud, this state is non‑destructive; on on‑prem, reconstruction/radiographs are deleted to free space.
</Card>

<Card title="Resource Management" iconType="regular">
  Usage-based model for storage and compute. Storage budgets are measured in terabytes (TB); on Cloud and GovCloud, an annual Token allocation covers compute‑intensive actions. Projects automatically migrate between tiers when limits are exceeded.
</Card>

<Card title="Token reset date" iconType="regular">
  The day Tokens refresh annually, typically your contract start (anniversary) date.
</Card>

<Card title="Tokens (per year)" iconType="regular">
  Annual allowance for compute‑intensive actions (e.g., reconstructions, bulk operations) in Cloud/GovCloud. Consumption and reset date are visible to Managers.
</Card>

## Voyager Software & Project Editor
