+# Release 2a DEB Packaging Filter Instructions
+
+## Required Changes to make_rpm_ubuntu26_release2.py
+
+The file `qt-migration-legatus/qt6-after/qt6-migrated-legatus/rpmbuild/make_rpm_ubuntu26_release2.py` needs to be updated to filter sources for Release 2a scope.
+
+**Note**: File is currently owned by root and requires sudo to modify.
+
+### Step 1: Add is_release2a_scope() function
+
+Add after the existing `is_dds_file()` function (around line 50):
+
+```python
+def is_release2a_scope(filepath, release_dirs=None):
+    """
+    Filter function for Release 2a scope (23 library targets only).
+    Excludes svc* services and non-scope directories.
+    
+    Args:
+        filepath: Path to check relative to source root
+        release_dirs: List of directories to include (optional)
+    
+    Returns:
+        True if file should be included in Release 2a packages
+    """
+    if release_dirs:
+        # Check if file is in one of the release scope directories
+        for rel_dir in release_dirs:
+            if filepath.startswith(rel_dir + '/') or filepath.startswith(rel_dir + os.sep):
+                return True
+            if filepath == rel_dir:
+                return True
+        return False
+    
+    # Default: include all files (fallback)
+    return True
+```
+
+### Step 2: Update release_dirs definition
+
+Replace the existing release_dirs definition (around line 475) with:
+
+```python
+# Release 2a scope: only directories containing the 23 library targets
+# NGL* libraries, qtsingle*, wms_json_ds, tcpserver, LtsCoordinate/LtsCoordTrans/LtsElevation, test libs
+release_dirs = [
+    "Z/src/NGLLogger",
+    "Z/src/nglapplication",
+    "Z/src/nglcompression",
+    "Z/src/nglcoreapplication",
+    "Z/src/ngldb",
+    "Z/src/nglguiapplication",
+    "Z/src/nglsettings",
+    "Z/src/nglsingleapplication",
+    "Z/src/nglsinglecoreapplication",
+    "Z/src/ngltools",
+    "Z/src/ngltranslator",
+    "Z/src/nglwidgets",
+    "Z/src/qtsingleapplication",
+    "Z/src/qtsinglecoreapplication",
+    "Z/src/wms_json_ds",
+    "Z/src/tcpserver",
+    "Lts/Common/LtsCoordinate",
+    "Lts/Common/LtsCoordTrans",
+    "Lts/Common/LtsElevation",
+    "Z/src/pdmTests",
+    "Z/src/eemTests",
+    "Z/src/flmTests",
+    "Z/src/srpFtTests",
+    "include/NGLLogger",
+    "include/nglapplication",
+    "include/nglcompression",
+    "include/nglcoreapplication",
+    "include/ngldb",
+    "include/nglguiapplication",
+    "include/nglsettings",
+    "include/nglsingleapplication",
+    "include/nglsinglecoreapplication",
+    "include/ngltools",
+    "include/ngltranslator",
+    "include/nglwidgets",
+    "include/qtsingleapplication",
+    "include/qtsinglecoreapplication",
+    "include/wms_json_ds",
+    "include/tcpserver",
+    "include/pdmTests",
+    "include/eemTests",
+    "include/flmTests",
+    "include/srpFtTests"
+]
+```
+
+### Step 3: Update copy_src_dir_to_dest_dir calls
+
+Update the three calls to use the new filter:
+
+**Line ~590** (Package 2):
+```python
+copy_src_dir_to_dest_dir(source_dir, pkg2_dir, release_scope=True, release_dirs=release_dirs, file_filter=is_release2a_scope)
+```
+
+**Line ~632** (Package 3):
+```python
+copy_src_dir_to_dest_dir(source_dir, pkg3_dir, release_scope=True, release_dirs=release_dirs, file_filter=is_release2a_scope)
+```
+
+**Line ~681** (Package 4):
+```python
+copy_src_dir_to_dest_dir(source_dir, pkg4_dir, release_scope=True, release_dirs=release_dirs, file_filter=is_release2a_scope)
+```
+
+## Execution
+
+Run with sudo:
+```bash
+cd qt-migration-legatus/qt6-after/qt6-migrated-legatus
+sudo nano rpmbuild/make_rpm_ubuntu26_release2.py
+# Apply changes above
+sudo python3 rpmbuild/make_rpm_ubuntu26_release2.py
+```
+

+  --build-group5 ON \
+  --build-group6 ON \
+  --lts-version 6.0.0 \
+  --project guez \
