# `deliver`
*since 1.0.0* 

```elixir
@callback deliver(incident :: struct(), opts :: keyword()) ::
  {:ok, term()} | {:error, term()}
```

Delivers a notification for the given incident to one adapter.
Implemented by concrete notification adapters (e.g., Slack, Teams).

# `broadcast`
*since 1.0.0* 

Dispatches a notification for the given incident to all configured notifiers.
Uses Oban for async delivery when available; falls back to `Task.start/1`.

# `dispatch`
*since 1.0.0* 

Dispatches a single notification to the given adapter with the provided opts.
Enqueues via Oban when available; otherwise executes in a supervised Task.
