# `Jido.Chat.Signal.PollingWorker`
[🔗](https://github.com/agentjido/jido_chat_signal/blob/v1.0.0/lib/jido_chat_signal/polling_worker.ex#L1)

Bridge-ingress polling worker for Signal receive transports.

The worker drains pending Signal envelopes through a receiver module and emits
raw payloads via `sink_mfa` so host runtimes can route them through ingress.

# `sink_mfa`

```elixir
@type sink_mfa() :: {module(), atom(), [term()]}
```

# `state`

```elixir
@type state() :: %{
  bridge_id: String.t(),
  sink_mfa: sink_mfa(),
  sink_opts: keyword(),
  receiver: module(),
  receiver_opts: keyword(),
  poll_interval_ms: pos_integer(),
  max_backoff_ms: pos_integer(),
  backoff_ms: pos_integer()
}
```

# `child_spec`

Returns a specification to start this module under a supervisor.

See `Supervisor`.

# `start_link`

```elixir
@spec start_link(keyword()) :: GenServer.on_start()
```
