Scala and TypeScript Synergy

" summary

A real-time collaborative text editor embeds into a legacy monolith using Scala backend + TypeScript (Angular) frontend with Java interop, avoids third‑party cloud or unapproved OSS, and runs in air‑gapped, multi‑device military environments. Conflict resolution uses operational transformation implemented on both client and server so inserts/deletes remain commutative and idempotent over WebSocket notifications; paragraph‑level classification/redaction and undo/redo are implemented, and the system achieves consistent, responsive shared editing without manual merge steps.
