Bridge: dispatch — ErrorBoundary + build.sh hardening from Gemini consultation

Priority order:
1. ErrorBoundary.tsx wrapping widget injection
2. set -e + tsc --noEmit pre-flight in build.sh
3. Pre-commit PHP lint hook
4. Dev Panel test before live panel

+# Chronicler Dispatch — Build Pipeline Hardening (Gemini Consultation Complete)
+
+**Date:** April 13, 2026
+**From:** Chronicler #84 — The Meridian
+**To:** Code
+
+---
+
+## What Happened Tonight
+
+The new v1.1.0 widget caused the entire server info card to disappear on the live panel.
+Root cause: React unmounts the entire component tree on uncaught runtime errors.
+We emergency-reverted. Panel is stable. Backend v1.1.0 is deployed. Frontend still on v1.0.0.

+
+## What Code Needs to Build (In Order)
+
+### 1. ErrorBoundary.tsx — FIRST PRIORITY
+
+Create `views/server/ErrorBoundary.tsx`:
+
+```tsx
+import React, { Component, ErrorInfo, ReactNode } from "react";
+
+interface Props { children?: ReactNode; fallback?: ReactNode; }
+interface State { hasError: boolean; }
+
+class ModpackErrorBoundary extends Component<Props, State> {
+  public state: State = { hasError: false };
+
+  public static getDerivedStateFromError(_: Error): State {
+    return { hasError: true };
+  }
+
+  public componentDidCatch(error: Error, errorInfo: ErrorInfo) {
+    console.error("ModpackChecker Component Error:", error, errorInfo);
+  }
+
+  public render() {
+    if (this.state.hasError) {
+      return this.props.fallback || (
+        <div className="text-gray-400 text-xs px-2 py-1">Modpack module unavailable.</div>
+      );
+    }
+    return this.props.children;
+  }
+}
+
+export default ModpackErrorBoundary;
+```
+
+Update build.sh injection to wrap the component:
+```bash
+# Instead of injecting: <ModpackVersionCard />
+# Inject: <ModpackErrorBoundary><ModpackVersionCard /></ModpackErrorBoundary>
+# Also add the import for ModpackErrorBoundary
+```
+
+### 2. build.sh Hardening
+
+Add at the very top:
+```bash
+set -e
+set -u
+```
+
+Add pre-flight TypeScript check BEFORE yarn build:
+```bash
+echo "Running pre-flight TypeScript check..."
+yarn tsc --noEmit 2>&1 | head -20 || {
+    echo "❌ TypeScript validation failed — aborting build"
+    exit 1
+}
+echo "✓ TypeScript check passed"
+```
+
+Fix Blueprint controller detection (use find instead of hardcoded path):
+```bash
+BP_CONTROLLER=$(find app/Http/Controllers/Admin/Extensions/modpackchecker -name "*Controller.php" | head -n 1)
+if [ -n "$BP_CONTROLLER" ]; then
+    cp "$EXT_DIR/admin/controller.php" "$BP_CONTROLLER"
+    echo "✓ Overwrote Blueprint controller"
+else
+    echo "❌ Blueprint controller not found"
+    exit 1
+fi
+```
+
+### 3. Pre-commit PHP Lint Hook
+
+Add to repo as `scripts/pre-commit-hook.sh` (Chronicler will install manually):
+```bash
+#!/bin/bash
+FILES=$(git diff --cached --name-only --diff-filter=ACMR | grep ".php$")
+for FILE in $FILES; do
+    php -l "$FILE" || { echo "Aborting commit: PHP syntax error in $FILE"; exit 1; }
+done
+exit 0
+```
+
+This permanently kills the */6 docblock problem at the source.
+

+
+## Deployment Order After Code Pushes
+
+1. Dev Panel first — test the ErrorBoundary catches gracefully
+2. Verify: if widget crashes, card shows "Modpack module unavailable" not a blank void
+3. Live panel ONLY after Dev Panel confirms stable
+
+Do NOT file a deploy request until ErrorBoundary is confirmed working on Dev Panel.
