 # aicodeman
 
+## 0.4.2
+
+### Patch Changes
+
+- Extract monolithic app.js (~12.5K lines) into 6 focused domain modules that extend CodemanApp.prototype via Object.assign: terminal-ui.js (terminal setup, rendering pipeline, controls), respawn-ui.js (respawn banner, countdown, presets, run summary), ralph-panel.js (Ralph state panel, fix_plan, plan versioning), settings-ui.js (app settings, visibility, web push, tunnel/QR, help), panels-ui.js (subagent panel, teams, insights, file browser, log viewer), session-ui.js (quick start, session options, case settings). Fix critical deferred script init ordering bug: wrap CodemanApp instantiation in DOMContentLoaded so all defer'd mixin modules execute their Object.assign before the constructor runs. Guard missing cleanupWizardDragging() call in subagent-windows.js. Update build.mjs to minify/hash all new modules.
