# `Mead.Deck.Interaction`
[🔗](https://github.com/albertosca/mead/blob/main/lib/mead/deck/interaction.ex#L1)

The `Mead.Router.Interaction` of a deck turn: every question and every progress report is a call
into the `Mead.Deck.Channel` of the session, which owns the policy, the event log and the clock.

The context is `%{channel: pid, turn_id: String.t()}`. `request_permission/2` returns only when
the channel has an answer, however long that takes (the channel's own deadline ends the wait),
so the calls use an infinite timeout. A channel that is gone takes the turn down with it, which
is right: the session it belongs to is gone too.
