# `MingaEditor.Shell.Board`
[🔗](https://github.com/jsmestad/minga/blob/main/lib/minga_editor/shell/board.ex#L1)

The Board shell: agent supervisor card view.

Displays agent sessions as cards on a spatial grid. Each card shows
task description, status, model, and elapsed time. Clicking a card
(or pressing Enter) zooms into its workspace for full editing.

The Board stays the active shell even when zoomed into a card. In
grid mode, it renders the card grid and handles navigation input.
In zoomed mode, it delegates rendering and input to the traditional
editor pipeline for the active card's workspace.

## Two rendering modes

- **Grid view** (`zoomed_into: nil`): card rectangles with status
  badges, task text, and model labels. Board-specific input handlers.
- **Zoomed view** (`zoomed_into: card_id`): full editor rendering
  using the card's restored workspace. Traditional input handlers
  plus an Escape binding to zoom back out.

# `on_buffer_added`

```elixir
@spec on_buffer_added(
  MingaEditor.Shell.Board.State.t(),
  MingaEditor.Workspace.State.t(),
  pid(),
  atom()
) ::
  {MingaEditor.Shell.Board.State.t(), MingaEditor.Workspace.State.t()}
```
