 This ensures .local/.gitea directories are **physically removed** from the Git tree before any GitHub push, providing ironclad protection against exposure of sensitive development documentation.
 
+## 🔄 ONGOING SYNCHRONIZATION MANAGEMENT (September 23, 2025)
+
+### 📊 Repository Sync Status Resolved
+**Issue Discovered:** GitHub dev/main branches were behind Gitea by several commits
+- **GitHub branches**: Stuck at `ae60fad` (old README merge)
+- **Gitea main**: Had progressed to `8329098` (latest workflow enhancements)
+- **Problem**: GitHub showing "recent pushes" but "nothing to compare"
+
+**Resolution Applied:**
+- ✅ **Executed sync command** - `sync-script.sh sync` to bring GitHub current
+- ✅ **Force-pushed clean history** - Updated both GitHub main and dev to `84d65f8`
+- ✅ **Privacy maintained** - All .local/.gitea files excluded during sync
+- ✅ **Authorship cleaned** - Filter-branch applied to ensure SBCrumb-only attribution
+
+**Current Synchronized State:**
+- **Gitea main**: `8329098` (includes private development files)
+- **GitHub main/dev**: `84d65f8` (clean public version, excludes private files)
+- **Sync differential**: 1 commit difference due to .local/.gitea exclusion (expected behavior)
+
+**Note on GitHub "Recent Pushes":**
+GitHub may continue showing "recent activity" due to force-push timestamp updates even when content is synchronized. This is normal GitHub behavior and doesn't indicate sync issues.
+
 **SUCCESS METRICS:**
 - ✅ **Zero personal information** on public GitHub
 - ✅ **Zero AI attribution** anywhere visible
