# How Signals become Lenses

Signals are the information available inside a Unit. Lenses are the shared insights Orbit synthesizes from those signals.

## What counts as a signal

A signal can come from:

* A description or status change
* A Thread message or poll
* An Attachment
* A Relationship or dependency
* A time entry or estimate
* A Document or Diagram
* A meeting recording, transcript, or note
* A connected source item
* A supported provider comment from Jira, Azure DevOps, Linear, monday.com, or Wrike

## What a Lens is

A Lens is one synthesized insight. It can draw from one or more sources and shows when it was produced and how much supporting signal is available.

The current categories are:

1. Decisions
2. Actions
3. Risks
4. Opportunities
5. Open Questions
6. Next Steps

## Lenses are shared

Everyone with access to the Unit can use its shared Lenses. This differs from private Orbit chats.

The current product displays these six built-in categories. It does not expose a custom Lens builder in the reviewed code.
