const SEAT_RING: usize = crate::conversation_window::CONVERSATION_CAP /* 4_000usize */;Expand description
How many frames one seat’s stream keeps for repair.
Sized from the window a client is served from, like the conversation copy the transport holds: it is the stretch a repair is answered from memory, and what falls past it is the transcript’s own read. A ring is shed whole at an occupant change - the numbers start over, so the frames before one are unreachable.
