Module: WhereIsWaldo::RosterDelivery

Defined in:
app/services/where_is_waldo/roster_delivery.rb

Overview

Pluggable roster delivery strategies. Each app picks a mode per account (via config.roster_mode); the channels dispatch to the matching strategy. The data model (aggregation) and the wire message shapes are shared across all modes — only the transport/trigger differs, so the client reducer never forks.

Strategies are pure/stateless (any state lives in Rails.cache): they COMPUTE streams + messages and perform cache/broadcast side effects, but the channel owns the actual ActionCable transmit/stream_from.
