Put Verbs in your database
summary
Builds a Laravel based event sourced web game and a reusable verbs package that stores actions as events instead of mutating status columns, then projects those events into tables. Shows data migrations for six timestamps and two models, a state object with validation and state-machine guards, tests that prevent duplicate events, and replay-safe notifications; live demo has hiccups but recorded live code exists. Claims easier refactors, simple queries and practical time travel.
