---
+Thought Process
+This is very helpful. It says that in Blender 5.0, bone selection state is now stored on the **pose bone** itself rather than on the bone data. So instead of `rep.data.bones[name].select_head`, we should use the pose bone directly.
+
+Let me search for more specific information about how to select bones via the pose bone.

+There's a `select` property on PoseBone at line 459. Let me read around that line.Tool use: **read_file_v2** • Read file: C:\Users\Nathan\.cursor\projects\t-Dynamic-Link-Manager\agent-tools\2b59cbcc-6d6a-46a9-ac24-052eb68b5ed5.txt
+
+Thought Process
+The `select` property exists on PoseBone in Blender 5.0. So the correct way to select bones in Blender 5.0 is:
+```python
+rep.pose.bones[name].select = True
+```
+
+Let me update the tweak_tools.py file to use this.Tool use: **edit_file_v2** • Edit file: T:/Dynamic-Link-Manager/ops/tweak_tools.py

+Fixed. The correct API for Blender 5.0 is `rep.pose.bones[name].select = True`.Thought Process
+Let me look at the current constraint retargeting logic in `run_retarg_relatives`. The user is saying that constraints on bones of characters that aren't the origchar or repchar are not being remapped.
+
+Let me read the migrator.py file to see the current implementation.Tool use: **read_file_v2** • Read file: T:/Dynamic-Link-Manager/ops/migrator.py
+
+Thought Process
+I see the issue. The code at lines 490-494 handles object-level constraints (where `c.target` is an object), but it doesn't handle **bone constraints** on other characters.
+
+Bone constraints are on `ob.pose.bones[...].constraints`, not on `ob.constraints`. The current code only looks at object-level constraints (`ob.constraints`).
+
+I need to add logic to iterate through all armatures and check their pose bones' constraints, retargeting any that point to `orig` to point to `rep` instead.Tool use: **edit_file_v2** • Edit file: T:/Dynamic-Link-Manager/ops/migrator.py
+
+Thought Process
+Good, I've added bone constraint retargeting. Now any constraint on any bone of any armature that targets the original character will be retargeted to the replacement character.

+Good, no linter errors. The fix adds a new loop that goes through all armatures in the scene and checks each pose bone's constraints, retargeting any that point to `orig` to point to `rep` instead.
