Datalog all the way down
summary
Builds a Clojure/Clojurescript stack that actually syncs Datomic to in‑browser DataScript, using Datomic and DataScript, posh reactions, and a utility library dat-sync (metaSaurus/dat-sync). Streams Datomic transaction reports to clients, transacts them into local databases, auto-updates DataScript schema, and generates dynamic UI from Datomic schema (pull queries drive editable forms). Prototype works but hits performance pain with many fine-grained queries; posh pattern-matching and reactive filters reduce reruns and improve scalability.
