- Add Mozo::Counter::Redis with same get/set/incr/decr interface - Add redis gem (~> 5.0) to Gemfile - Update cable.yml to use Redis adapter in production (shared with counters) - Document DrbCounter → Redis migration in broadcasting-migration.md - Redis installed and running on vmi3300327 - Leave Faye as current broadcaster; both switches are one-line changes DrbCounter problems solved: - In-memory → persistent (RDB + AOF) - Single-process DRb → multi-process safe Redis - Atomic INCR/DECR across Puma workers - One less custom process to manage
