Here’s what was implemented:
### 1. Rig family selector ([`ui/properties.py`](ui/properties.py), [`ui/panels.py`](ui/panels.py))
- Added `migrator_rig_family` **`EnumProperty`**: **Rigify** | **ARP** (default Rigify).
- First row under “Character Migrator” uses **`expand=True`** for the two buttons.
### 2. Collection resolver ([`utils/remove_original.py`](utils/remove_original.py))
- **`resolve_collection_for_remove_original(orig, rig_family, scene)`**:
- Picks the **deepest** `users_collection` entry (most nested).
- Walks **up** to `scene.collection` via **`_parent_collection`**.
- Chooses the remove target:
- **Linked armature:** outermost collection in that chain whose **`library.filepath`** matches **`orig.library`**.
- **Override:** outermost collection with **`override_library`** set when **`orig.override_library`** is set.
- **Rigify:** optional name match (`_Rigify`, base name) on the way **down** from the top of the chain.
- **ARP:** no `_Rigify` stripping; hierarchy + defaults rule.
- Default: **`chain[-1]`** (top of the branch under the scene).
### 3. Remove Original ([`ui/operators.py`](ui/operators.py))
- Imports **`resolve_collection_for_remove_original`** (replaces **`collection_containing_armature`** for this operator).
- Reads **`migrator_rig_family`** from scene props.
- Tries **`bpy.data.collections.remove()`**; on failure, **warns** and falls back to **`bpy.data.objects.remove(orig, do_unlink=True)`**.
- If the resolver returns **None**, removes the object only (unchanged idea).
- **Action purge and `.rep` rename** on the replacement are unchanged.
`collection_containing_armature` in [`utils/__init__.py`](utils/__init__.py) is unchanged for **MigBBody** and other callers.

_**User**_
So far, CopyAttr and MigNLA need no rig type-specific behavior; current behavior is sufficient for both.
MigNLA needs to do one special thing: It needs to select the RepChar before activating animlayers.

Here’s what changed:
### `run_mig_nla` + Animation Layers active object
- Added **`_rep_active_for_animlayers(context, rep)`** (`contextlib.contextmanager`): sets **`context.view_layer.objects.active = rep`** before AnimLayers handling, then restores the previous active object if it still exists.
- **`run_mig_nla(orig, rep, report=None, context=None)`** wraps both **`_mirror_als_turn_on(orig, rep)`** calls (no‑NLA path and NLA path) in that context manager.
- **`run_full_migration`** now calls **`run_mig_nla(orig, rep, context=context)`**.
- **`DLM_OT_migrator_migrate_nla`** passes **`context=context`** into **`run_mig_nla`**.
If **`context` is omitted** (e.g. scripts), behavior is unchanged and AnimLayers mirroring runs without forcing selection.
---
_**User**_
@c:\Users\Nathan\.cursor\projects\t-Dynamic-Link-Manager\terminals\3.txt doesn't work; if I select origchar, repchar is not selected first. the reason I'm trying to do this is because if repchar is not active when mignla is ran, animlayers will not be activated on repchar and the user must select repchar and activate animlayers again.

**Investigating restore issue**
The issue may be that we're restoring the original active object too early in the `finally` block, before animation layers can process it. The addon likely needs the replacement object to remain active during AnimLayers processing, not the original object. I'll leave `rep` as the active object after MigNLA completes to keep AnimLayers UI active on the replacement object. I'll set rep as active before `_mirror_als_turn_on` and avoid restoring previous active object.
**Testing object activation**
I'm testing if `vl.objects.active = rep` works when rep is hidden or obscured. I need to ensure `rep` is in the current view layer and not hidden or excluded from selection. I'm checking if `rep` needs to be selected explicitly with `Object.select_set(True)` to become active. Setting `view_layer.objects.active = obj` requires `obj.select_set(True)` and object to be in view layer.
**Setting object selection**
I'm using the view layer API to properly deselect all objects before setting the active object. I'm switching to object mode before selecting the replacement object to ensure compatibility across modes. I'm setting the replacement object as active before entering object mode to ensure proper selection.
**Handling mode switching**
I need to switch modes before setting the replacement object as active to avoid conflicts with armature parenting. I need to ensure proper mode switching before setting the replacement object as active to avoid armature parenting conflicts. I'm implementing robust activation logic that ensures proper mode switching before setting the replacement object as active. I'm refining the object selection logic to properly set the active object in Blender. I'm optimizing object selection by using `bpy.ops.object.select_all` instead of looping through objects. I'm switching to OBJECT mode from POSE mode and deselecting all objects before selecting the replacement object.
I'm updating the `_rep_active_for_animlayers` function to enter OBJECT mode, select the replacement object, and skip restoring the active object afterward. I'm implementing the selection restoration logic with try/except for `select_all` and using `context.temp_override` for proper window context. </details></think>
