Module: Mbeditor::WorkspaceRootResolver

Defined in:
app/services/mbeditor/workspace_root_resolver.rb

Overview

Single source of truth for locating the workspace root. Used by both the HTTP controllers and the ActionCable channel so the git rev-parse subprocess runs at most once per process instead of once per call site.
