+# Release 2a DEB Packaging Filter - Manual Application Required
+
+## Issue
+The file `rpmbuild/make_rpm_ubuntu26_release2.py` is owned by root and requires sudo to modify.
+
+## Required Changes
+Add Release 2a scope filtering to exclude:
+- All svc* service directories (Release 2b scope)
+- Test executable directories (*Tests)
+- LtsElevation module (depends on excluded AssetManagement)
+- AssetManagement plugin
+
+## Option 1: Apply Patch (Recommended)
+
+```bash
+cd /home/torsten/sandbox/qt6-migration-pipeline/qt-migration-legatus/qt6-after/qt6-migrated-legatus
+sudo patch -p1 < /tmp/make_rpm_ubuntu26_release2.patch
+```
+
+## Option 2: Manual Edit
+
+Edit `rpmbuild/make_rpm_ubuntu26_release2.py` with sudo:
+
+### Step 1: Add filter function after imports (after line 30)
+
+```python
+def is_release2a_scope(filepath):
+    """Check if file/directory is outside Release 2a scope (libraries only)
+    
+    Release 2a scope: 18 library targets (no services, no test executables)
+    Returns True to EXCLUDE, False to INCLUDE
+    
+    Excluded:
+    - All svc* service directories
+    - Test executable directories (*Tests)
+    - LtsElevation (depends on excluded AssetManagement)
+    - AssetManagement plugin
+    """
+    filepath_str = str(filepath)
+    
+    # Exclude svc* services (Release 2b scope)
+    if '/svc' in filepath_str.lower():
+        return True
+    
+    # Exclude test executables (Release 2a is libraries only)
+    test_patterns = ['Tests/', 'Tests\\', '_Tests/', '_Tests\\']
+    for pattern in test_patterns:
+        if pattern in filepath_str:
+            return True
+    
+    # Exclude LtsElevation (depends on excluded AssetManagement)
+    if 'LtsElevation' in filepath_str:
+        return True
+    
+    # Exclude AssetManagement plugin
+    if 'AssetManagement' in filepath_str:
+        return True
+    
+    return False
+```
+
+### Step 2: Update 3 copy_src_dir_to_dest_dir calls
+
+**Line ~625** (Package 2 - qt6-release-sources):
+```python
+# OLD:
+copy_src_dir_to_dest_dir(source_dir, pkg2_dir, release_scope=False, release_dirs=release_dirs)
+
+# NEW:
+copy_src_dir_to_dest_dir(source_dir, pkg2_dir, release_scope=False, release_dirs=release_dirs, file_filter=is_release2a_scope)
+```
+
+**Line ~668** (Package 3 - qt6-release-ctest-runtime):
+```python
+# OLD:
+copy_src_dir_to_dest_dir(source_dir, pkg3_dir, release_scope=False, release_dirs=release_dirs)
+
+# NEW:
+copy_src_dir_to_dest_dir(source_dir, pkg3_dir, release_scope=False, release_dirs=release_dirs, file_filter=is_release2a_scope)
+```
+
+**Line ~718** (Package 4 - qt6-release-ctest-sources):
+```python
+# OLD:
+copy_src_dir_to_dest_dir(source_dir, pkg4_dir, release_scope=False, release_dirs=release_dirs)
+
+# NEW:
+copy_src_dir_to_dest_dir(source_dir, pkg4_dir, release_scope=False, release_dirs=release_dirs, file_filter=is_release2a_scope)
+```
+
+## After Applying Changes
+
+Run validation build with DEB packaging:
+
+```bash
+cd /home/torsten/sandbox/qt6-migration-pipeline/qt-migration-legatus/qt6-after/qt6-migrated-legatus
+./new_docker_build_release2.sh --group1 --group3 --group5 --group6 --build-type Release --deb-package
+```
+
+## Verification
+
+After build completes, verify DEB packages contain only Release 2a scope files:
+- No svc* directories
+- No *Tests directories (except test framework files)
+- No LtsElevation
+- No AssetManagement
