Character migrator workflow integration (2026-02-18 23:39Z)

User

We're going to do a major overhaul. Everything that came before is obsolete. I have designed a character migrator workflow. We will integrate it into this project. Here's the context for the workflow:@a:\1 Amazon_Active_Projects\260206_PAE_2026.specstory\history\2026-02-17_17-20Z-linked-library-override-resync-issue.md

Agent (model default, mode Agent)

Thought Process

The user wants to do a major overhaul of the Dynamic-Link-Manager project. They've designed a "character migrator workflow" and want to integrate it. They've referenced a spec story history file that contains the context for the workflow. I need to:

Read the referenced file to understand the character migrator workflow design
Understand the current state of the Dynamic-Link-Manager project
Create a plan for integrating the workflow into the project

Let me start by reading the referenced file and exploring the current project structure. I'm in plan mode, so I should not make any edits - only gather information and create a plan.

Reading the workflow spec and exploring the project so we can plan integrating the character migrator.

Tool use: **read_file_v2** • Read file: a:\1 Amazon_Active_Projects\260206_PAE_2026\.specstory\history\2026-02-17_17-20Z-linked-library-override-resync-issue.md

Thought Process

The spec story file is huge (over 1M characters). I need to read it in chunks or search for the character migrator workflow design. Let me read the beginning of the file to understand its structure, and search for key terms like "character migrator", "workflow", "migrator", etc.

Thought Process

The spec file is a long transcript about a linked library override resync issue in Blender - it doesn't seem to contain the words "character migrator" or "migrator workflow". The user said they "designed a character migrator workflow" and the context is in that file. Maybe the design appears later in the document, or under different terms. Let me search for other keywords: "workflow", "migrat", "design", "overhaul", "character", or look at the end of the file where conclusions/design might be.

Thought Process

I'm getting a clearer picture. The spec story is a long transcript of a Blender support session. It evolved into a character replacement/migration workflow that was run repeatedly for different characters (Una, Steve, Eddy, Hailey). The workflow is not explicitly named "character migrator" in the doc but it's clearly the same thing. Key elements from the transcript:

The workflow (steps 1–7):

Copy attributes – Copy rotation, location, scale on each armature object from original to replacement (and link/override characters if needed).
Migrate NLA – Copy NLA tracks from original to replacement, with blend_type matched (e.g. COMBINE).
Custom properties – Copy pose-bone custom props from original to replacement (exclude _RNA_UI, rigify_type, rigify_parameters).
Bone constraints – Copy constraints to replacement; skip when target is same character's original; retarget when target is another character's original → that character's replacement; remove stale constraints on rep that target other's original first.
Retarget relations – Parents, constraint targets, Armature modifiers pointing at original → point to replacement; also objects outside the character that target the original.
Replacement base body – Library override only (NO single-user copy): for rep's base body mesh, if linked call override_create(), then assign shape-key action. Do NOT do ob.data.copy().
Remove duplicate constraints – Trim rep's bone constraints so count matches original (remove from end).

Additional rules from the transcript:

When replacing an armature, update any relations (objects/empties, constraints, modifiers, drivers, parenting) that point to the old armature to point to the new one.
Cross-character constraints: e.g. Eddy looking at Hailey → when copying to Eddy.001, retarget the constraint to Hailey.001; and remove from the rep any constraint that still targets the other character's original before re-adding with correct target.
NLA strip blend_type should be copied (e.g. COMBINE).
Optional: COPY_TRANSFORMS on control bones from original to replacement so they move together – but user also wanted "Steve.001 independent" (no dependency on Steve), so sometimes skip COPY_TRANSFORMS.

Current Dynamic-Link-Manager project:

Blender add-on: "Dynamic Link Manager" – relink characters and library blends.
Has operators for: replace_linked_asset, scan_linked_assets, and likely more (relink, path management).
UI in ui.py, logic in operators.py.

The user wants to:

Treat everything before as obsolete.
Integrate this character migrator workflow into the Dynamic-Link-Manager project.

So the plan is: Major overhaul – replace or significantly reshape the add-on around the character migrator workflow (detect original/replacement armature pairs, run steps 1–7 with the rules above). I need to read more of the spec to see if there's a canonical step list or any more design (e.g. how to discover "pairs", UI, etc.) and also read more of operators.py and ui.py to see what to remove or keep.

Searching the spec for the full step list and discovery of character pairs, and reviewing the add-on's operators and UI.

Thought Process

I now have a good picture:

Character migrator workflow (from spec):

Copy attributes – Location, rotation, scale on armature object from original → replacement
Migrate NLA – Copy NLA tracks to replacement, matching blend_type (e.g. COMBINE)
Custom properties – Copy pose-bone custom props (exclude _RNA_UI, rigify_type, rigify_parameters)
Bone constraints – Copy to rep; skip when target == same orig; retarget when target == other character's orig → other's rep; first remove from rep any constraint targeting other's orig
Retarget relations – Parents, constraint targets, Armature modifiers, and any object targeting orig → point to rep
Replacement base body – Library override only (override_create(), no single-user copy), then assign shape-key action
Remove duplicate constraints – Trim rep constraints to match orig count

Pair discovery: In the spec they use hardcoded names (Hailey/Eddy, Steve, Una) and pattern like BaseName_Rigify (original) and BaseName_Rigify.001 (replacement). So pairs are (orig_armature, rep_armature) where rep is typically in a collection like "Character.001" and has name "Character_Rigify.001". The workflow can be run for one or multiple character pairs; the code built a list of pairs and an orig→rep map for cross-character retargeting.

Current add-on: Dynamic Link Manager – focuses on scanning linked libraries, finding missing ones in folders, relinking, opening linked files. No character migration. The user wants to obsolete all of that and make the add-on centered on the character migrator workflow.

I'll create a plan that:

Summarizes the workflow from the spec (7 steps + rules)
Proposes replacing/overhauling the add-on to be "Character Migrator" or keep the name but make migration the primary feature
How to discover pairs (configurable or by convention: e.g. user selects orig + rep, or we scan for Name_Rigify / Name_Rigify.001)
UI: run full workflow, maybe run individual steps, select character pair(s)
What to remove (existing operators/UI that are obsolete) vs what to keep (e.g. search paths might still be useful if we ever need to link in assets – but user said "everything that came before is obsolete")

Let me check if there's more in the spec about how they want to "integrate" (e.g. UI, selection) and read a bit more of operators.py to list all current operators.

Checking the rest of the operators and UI to list current features and locate the workflow's step 1 (copy attributes).

Thought Process

I have a clear picture. The spec document is a long transcript; the canonical workflow is the 7-step process that was refined over many messages (Hailey/Eddy run at the end). Key details:

Workflow steps (final form):

Copy attributes (location, rotation, scale) on armature object from original → replacement
Migrate NLA (tracks + strips, blend_type, etc.) from original → replacement
Custom properties on pose bones (exclude _RNA_UI, rigify_type, rigify_parameters)
Bone constraints: skip target==orig; retarget target in orig_to_rep to rep; first remove from replacement any constraint that targets the other character's original
Retarget relations: parents, constraint targets, Armature modifiers, and any object targeting orig → rep
Replacement base body: library override only (override_create(), no copy), assign shape-key action
Remove duplicate constraints (trim rep to match orig count)

Pair discovery: Pairs are (base_name, orig_armature, rep_armature) where orig = e.g. Name_Rigify, rep = Name_Rigify.001. The code uses a hardcoded list of base names ('Hailey', 'Eddy') or ('Steve',) etc. For integration we need a way to get pairs - either user selection (two armatures) or scan by convention (find all Name_Rigify and Name_Rigify.001).

Optional: COPY_TRANSFORMS on control bones was sometimes skipped to make the replacement "independent" (so original can be purged). So that could be an option in the add-on.

Now I'll create the plan. The user said "everything that came before is obsolete" - so we're replacing the add-on's purpose with the character migrator. We could keep the add-on name "Dynamic Link Manager" and add the migrator as the main feature, or rename. I'll propose making the character migrator the core and either removing or demoting the old library-scan/relink features.

Thought Process

The workflow in the spec always uses explicit character base names (Hailey, Eddy, Steve, Una) and the convention BaseName_Rigify (original) and BaseName_Rigify.001 (replacement). So for integration we need either:

User-provided list of base names (e.g. from a preference or a text field), or
User selects two armatures (original and replacement) and we run for that single pair, or
Auto-detect: find all armatures named like *._Rigify and *._Rigify.001 and group by base name.

I'll include in the plan that pair discovery can be: (A) selection-based (two armatures = one pair), or (B) convention-based (scan for Name_Rigify / Name_Rigify.001), with optional configurable base names.

  "plan": "# Character Migrator Workflow Integration\n\n## Source of truth\n\nThe workflow is fully specified in the SpecStory transcript you referenced: [2026-02-17_17-20Z-linked-library-override-resync-issue.md](a:\\1 Amazon_Active_Projects\\260206_PAE_2026\\.specstory\\history\\2026-02-17_17-20Z-linked-library-override-resync-issue.md). The transcript evolves from a library resync issue into a repeatable **character replacement** flow for Rigify characters (Una, Steve, Eddy, Hailey). The final 7-step formulation appears in the Hailey/Eddy run (steps 1–7) and the subsequent fixes (no single-user copy for body; cross-character constraint retargeting; remove stale constraints on rep that target other’s original).\n\n## Workflow summary (7 steps)\n\n| Step | What it does |\n|------|----------------|\n| **1** | Copy armature object attributes: location, rotation (quaternion/euler), scale from original to replacement. |\n| **2** | Migrate NLA: copy tracks and strips to replacement, preserving &#96;blend_type&#96;, &#96;extrapolation&#96;, &#96;frame_end&#96;, &#96;blend_in&#96;/&#96;blend_out&#96;, &#96;repeat&#96;. Create &#96;animation_data&#96; on rep if missing. |\n| **3** | Custom properties: copy pose-bone custom props from original to replacement; exclude &#96;_RNA_UI&#96;, &#96;rigify_type&#96;, &#96;rigify_parameters&#96;. |\n| **4** | Bone constraints: (a) On replacement, remove any constraint whose target is another character’s *original* armature. (b) Copy constraints from original to replacement: skip if target is same character’s original; if target is another character’s original, set new constraint target to that character’s *replacement*; else keep target. Copy name, mute, influence, subtarget, and common props (e.g. head_tail, use_bone_object, invert_*). (c) Trim replacement bone constraints so count per bone matches original (remove from end). |\n| **5** | Retarget relations: (a) Rep’s descendants: parent to rep if was parent to orig; constraint targets and Armature modifier object pointing at orig → rep. (b) Any object in the file whose parent is orig → parent to rep; any constraint target or Armature modifier pointing at orig → rep. |\n| **6** | Replacement base body: for each replacement’s base body mesh (mesh with “body” and “base” in name, skinned to rep): if mesh data is linked or override, call &#96;override_create()&#96; only (no single-user copy). Then assign the matching shape-key action if found (e.g. &#96;{body_name}Action&#96;, &#96;{mesh_data_name}Action&#96;, &#96;{body_name}Action.001&#96;). |\n| **7** | Implemented inside step 4: remove duplicate constraints on replacement so each bone’s constraint count matches the original. |\n\n## Pair discovery\n\nIn the spec, pairs are **(base_name, orig_armature, rep_armature)** with naming like &#96;Name_Rigify&#96; (original) and &#96;Name_Rigify.001&#96; (replacement). For integration, support at least:\n\n- **Selection-based:** User selects two armatures (active = replacement, other selected = original) and runs the workflow for that single pair. No need to know “base name”.\n- **Optional: convention-based** – Scan for armatures named &#96;*_Rigify&#96; and &#96;*_Rigify.001&#96; (same base) to build multiple pairs; use a single “Run migration” that runs steps 1–7 for all discovered pairs with a shared &#96;orig_to_rep&#96; map for cross-character retargeting in step 4.\n\nHelper used everywhere: **descendants(armature)** = objects whose parent chain leads to that armature.\n\n## Current add-on vs new direction\n\n- **Current:** [operators.py](T:\\Dynamic-Link-Manager\\operators.py) and [ui.py](T:\\Dynamic-Link-Manager\\ui.py) implement linked library scanning, missing/indirect detection, search paths, find-in-folders relink, reload, open blend, path relative/absolute, relocate single library. [blender_manifest.toml](T:\\Dynamic-Link-Manager\\blender_manifest.toml) describes the add-on as “Relink characters and library blends with ease.”\n- **Direction:** Treat existing behaviour as obsolete. Make the add-on’s primary purpose the **character migrator**. Either remove the old operators/UI or move them behind a “Legacy” / “Library tools” sub-panel so the main panel is migrator-only.\n\n## Proposed architecture\n\n&#96;&#96;&#96;mermaid\nflowchart LR\n  subgraph ui [UI]\n    Panel[Main Panel]\n    RunAll[Run full migration]\n    PairList[Pair list or selection]\n  end\n  subgraph core [Core]\n    Discover[Discover pairs]\n    Step1[Step 1: Copy attributes]\n    Step2[Step 2: NLA]\n    Step3[Step 3: Custom props]\n    Step4[Step 4: Constraints]\n    Step5[Step 5: Retarget relations]\n    Step6[Step 6: Base body override]\n  end\n  Panel --&gt; RunAll\n  Panel --&gt; PairList\n  RunAll --&gt; Discover\n  Discover --&gt; Step1 --&gt; Step2 --&gt; Step3 --&gt; Step4 --&gt; Step5 --&gt; Step6\n&#96;&#96;&#96;\n\n- **New module (recommended):** Add &#96;migrator.py&#96; (or &#96;character_migrator.py&#96;) containing:\n  - &#96;get_pairs_from_selection(context)&#96; → list of (base_name, orig, rep) from two selected armatures (optional: orig/rep order by name or by “.001”).\n  - &#96;get_pairs_by_convention(context, base_names)&#96; → list of pairs for given base names using &#96;Name_Rigify&#96; / &#96;Name_Rigify.001&#96;.\n  - &#96;run_step_1(orig, rep)&#96; … &#96;run_step_6(orig, rep, rep_descendants, orig_to_rep_map)&#96; with signatures that match the spec (step 4 and 5 need &#96;orig_to_rep&#96; for all pairs in the batch).\n  - One entry point: &#96;run_full_migration(context, pairs)&#96; that builds &#96;orig_to_rep&#96;, then for each pair gets &#96;descendants(rep)&#96; and runs steps 1–6 (with step 7 folded into step 4).\n- **Operators:** One operator, e.g. &#96;DLM_OT_run_character_migration&#96;, that (a) gets pairs from selection or from a convention/list, (b) calls &#96;run_full_migration&#96;. Optionally a “Run step N” operator for debugging.\n- **UI:** Main panel: “Character Migrator” section with “Run migration (selected armatures)” and, if implemented, “Run for all pairs” and a way to configure base names or list pairs. Remove or collapse current “Linked Libraries Analysis” into a secondary panel/section.\n\n## Important details from the spec\n\n- **No single-user copy for body:** Step 6 must use library override only (&#96;override_create()&#96;); do not do &#96;ob.data = ob.data.copy()&#96;.\n- **Cross-character constraints:** When copying a constraint to replacement A, if the constraint targets the *other* character’s original armature, set the new constraint’s target to that character’s replacement (and remove from the replacement any existing constraint that still targeted the other’s original).\n- **Base body detection:** Rep’s base body = mesh in &#96;descendants(rep)&#96; with &#96;\"body\"&#96; and &#96;\"base\"&#96; in name (case-insensitive) and Armature modifier pointing at rep.\n- **Shape-key action naming:** Try &#96;{body_obj_name}Action&#96;, &#96;{mesh_data_name}Action&#96;, &#96;{body_obj_name}Action.001&#96; (and similar variants if present in the spec).\n\n## Optional / future\n\n- **COPY_TRANSFORMS:** The spec sometimes added COPY_TRANSFORMS on control bones so rep follows orig in real time; other times it was omitted so the replacement stays independent (e.g. to purge original). Can be an add-on option (e.g. “Make replacement follow original”) later.\n- **Copy shape key values:** The spec also copies current shape key *values* from original body to replacement body in some runs; step 6 currently focuses on override + action. Copying values can be an extra step or option if you want parity with those runs.\n\n## Files to touch\n\n| File | Action |\n|------|--------|\n| New &#96;migrator.py&#96; | Add discovery helpers and step 1–6 (with 7 inside 4) from spec. |\n| [operators.py](T:\\Dynamic-Link-Manager\\operators.py) | Add &#96;DLM_OT_run_character_migration&#96; (and optionally per-step operators). Optionally remove or keep old operators. |\n| [ui.py](T:\\Dynamic-Link-Manager\\ui.py) | Replace or reorder main panel: Character Migrator primary; move linked-library UI to secondary or remove. Add any props for pair source (selection vs list). |\n| [__init__.py](T:\\Dynamic-Link-Manager\\__init__.py) | Import and register migrator operators (and migrator module if needed). |\n| [blender_manifest.toml](T:\\Dynamic-Link-Manager\\blender_manifest.toml) | Update description/tagline to reflect character migrator as main feature. |\n\n## Implementation order\n\n1. Add **migrator.py** with pure logic: &#96;descendants()&#96;, pair discovery (selection first), then &#96;run_step_1&#96; … &#96;run_step_6&#96; and &#96;run_full_migration()&#96; using the exact rules from the spec (including orig_to_rep for steps 4 and 5).\n2. Add **operator** that gets pairs (e.g. from selection: two armatures → one pair) and calls &#96;run_full_migration()&#96;; report errors and “Migrated N pairs” in the operator’s report.\n3. **UI:** One button “Run character migration” in the main panel (and short instructions: “Select original and replacement armatures”).\n4. **Clean-up:** Remove or demote old linked-library operators/UI; update manifest and __init__ as needed.\n5. (Optional) Add convention-based discovery and “Run for all” plus any options (e.g. COPY_TRANSFORMS, copy shape key values).\n\nThis keeps the spec’s workflow canonical and makes the add-on a thin UI + operator layer over a single, testable migrator core.\n",

Additions to the plan:

Keep everything for linked libraries analysis and put its boxes in their own dropdown underneath CharMig.

Discover pairs should have an automatic mode (already in the plan) and a manual mode where pairs are specified. Only one character should be migrated at a time. The migrator should have 2 fields. First should be the original character, second should be for the replacement character. These fields should have picker buttons that populate the field with the active armature when clicked. Many of the operators will need to manipulate datablocks other than the armature, so they should be able to view the linked collection that the armature is a part of in order to do so cleanly.

Our project should mirror the structure of this extension: T:\AmazonCharacterTools

Agent (model default, mode Agent)

Thought Process

The user wants to update the plan with several additions:

Linked libraries: Keep everything for linked libraries analysis and put its boxes in their own dropdown underneath "CharMig" (Character Migrator). So the main panel has CharMig first, then a collapsible section for linked libraries.
Pair discovery:
- Automatic mode (already in plan)
- Manual mode where pairs are specified
- Only one character migrated at a time (not batch)
Migrator UI:
- Two fields: "Original character" and "Replacement character"
- Picker buttons that populate the field with the active armature when clicked
- So it's manual selection via two fields + picker, not "select two objects and run"
Operators need to manipulate other datablocks: They should be able to "view" the linked collection that the armature is part of - meaning when working with a linked/overridden armature, we need to consider the collection context (e.g. to find descendants, base body meshes that belong to that character). So the logic needs to work with the collection that contains the armature, not just the armature in isolation.
Project structure: Mirror the structure of T:\AmazonCharacterTools. I need to look at that project's structure to understand what to mirror.

Let me read the AmazonCharacterTools structure first, then update the plan file.

Checking the structure of T:\AmazonCharacterTools to mirror it, then updating the plan with your additions.

Tool use: **read_file_v2** • Read file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

I need to see the actual folder structure of AmazonCharacterTools (excluding .git and .specstory) to mirror it. Let me list the top-level and key subdirs.

Tool use: **read_file_v2** • Read file: T:\AmazonCharacterTools\__init__.py

Tool use: **read_file_v2** • Read file: T:\AmazonCharacterTools\ui\__init__.py

Tool use: **read_file_v2** • Read file: T:\AmazonCharacterTools\ops\__init__.py

Thought Process

Let me get the full structure - list_dir didn't work, I'll use list_dir on the path. Actually the glob already showed the structure. Key dirs:

T:\AmazonCharacterTools\
- __init__.py (main entry)
- blender_manifest.toml
- ui/
  - __init__.py (exports OPERATOR_CLASSES, PANEL_CLASSES, AMZN_AddonPreferences)
  - operators.py
  - panels.py
  - preferences.py
- ops/
  - __init__.py (empty / just docstring)
  - Various op files: Devices_FreshPlacement.py, Device_Replacement.py, etc.
- utils/
  - __init__.py

So the structure is:

Root: __init__.py, blender_manifest.toml
ui/: operators (UI-related?), panels, preferences; init aggregates CLASSES
ops/: one file per feature (operators)
utils/: helpers

I need to see how ops are registered - does __init__.py in root import from ops?

Tool use: **read_file_v2** • Read file: T:\AmazonCharacterTools\ui\panels.py

Tool use: **read_file_v2** • Read file: T:\AmazonCharacterTools\ui\operators.py

  "path": "T:\\AmazonCharacterTools",
  "glob": "*.py",
  "caseInsensitive": false
}

Additional data:

    {
      "uri": "..\\AmazonCharacterTools\\ui\\__init__.py",
      "matchCount": 2
    }
  ]
}

Status: completed

Thought Process

So AmazonCharacterTools structure:

Root __init__.py: imports from .ui only (OPERATOR_CLASSES, PANEL_CLASSES, AMZN_AddonPreferences), registers all.
ui/: __init__.py exports OPERATOR_CLASSES, PANEL_CLASSES, AMZN_AddonPreferences.
- operators.py: defines OP_SPECS (list of dicts: name, id, script, button, icon, panel); OPS_DIR = parent/ops; OPERATOR_CLASSES = dynamic operators that run scripts from ops/.
- panels.py: defines panels that reference OP_SPECS; PANEL_CLASSES.
- preferences.py: AMZN_AddonPreferences.
ops/: standalone Python scripts (e.g. SettingsBone.py) that get run via runpy from ui/operators.py. Each op is a spec that points to a script.

So for Dynamic-Link-Manager we need to mirror:

Root: __init__.py, blender_manifest.toml
ui/: __init__.py, operators.py (or keep operators that are UI-triggered here), panels.py, preferences.py
ops/: one module per feature; for DLM we have (1) all the current library ops and (2) character migrator. So we could have ops/migrator.py or ops/character_migrator.py and ops/library_*.py or keep library in one file.
utils/: shared helpers (e.g. descendants, path resolution)

The user said "mirror the structure" - so we need:

DLM root: __init__.py, blender_manifest.toml
ui/ with init, operators, panels, preferences
ops/ with migrator logic (and maybe library ops split out)
utils/ for helpers

Now update the plan with all additions:

Linked libraries: Keep everything; put in their own dropdown underneath CharMig.
Pair discovery: Automatic mode + Manual mode. Only one character at a time (single pair).
Manual mode UI: Two fields - "Original character", "Replacement character". Picker buttons that set the field to the active armature's name (or reference).
Collection context: Operators need to be able to "view" the linked collection the armature is part of so they can manipulate other datablocks (descendants, meshes) cleanly. So we need to resolve "the collection that contains this armature" (e.g. the root collection of that character - often the armature's users_collection or the collection that has the same base name).
Project structure: Mirror AmazonCharacterTools: ui/, ops/, utils/, root __init__.py.

I'll update the plan file with these additions and the new structure.

Checking how properties are stored in the AmazonCharacterTools UI:

Tool use: **read_file_v2** • Read file: T:\AmazonCharacterTools\ui\preferences.py

  ]
}

Status: completed

Thought Process

I have enough. Updating the plan with:

Linked libraries: keep everything, own dropdown underneath CharMig.
Pair discovery: automatic (convention) + manual. Only one character at a time (single pair).
Manual UI: two fields (original character, replacement character) + picker buttons that set from active armature.
Collection context: migrator/operators should resolve the linked collection that the armature belongs to so they can work with descendants/other datablocks cleanly.
Project structure: mirror AmazonCharacterTools → ui/, ops/, utils/, root __init__.py; ops/ for migrator (and library) logic; ui/ for panels, operators (that invoke ops), preferences.

Writing the plan update.

Updating the plan with your additions and the AmazonCharacterTools structure.

Tool use: **edit_file_v2** • Edit file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

Now update the architecture section to reflect: (1) project structure mirroring AmazonCharacterTools, (2) manual vs automatic mode, (3) two fields + pickers, (4) collection context.

Tool use: **edit_file_v2** • Edit file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

Now update the "Files to touch" and "Implementation order" sections to reflect the new structure (ui/, ops/, utils/) and the additions (linked libs kept in dropdown, manual/auto, pickers, collection context).

The string to replace was not found in the file.

Thought Process

The table has different formatting (extra spaces). Let me try replacing just the "## Files to touch" section through the end of implementation order in smaller chunks.

Tool use: **read_file_v2** • Read file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

I see - the table uses | with spaces. Let me do the replace in one go with the exact content.

The string to replace was not found in the file.

Thought Process

The issue might be with the pipe characters in the table or some encoding. Let me try replacing just the "## Files to touch" header and the table and implementation order in two smaller replacements. First replace from "## Files to touch" through the table (up to and including the blank line before "## Implementation order").

Tool use: **edit_file_v2** • Edit file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

Good, that worked. Now replace the implementation order section.

The string to replace was not found in the file.

Thought Process

The quotes might be different - curly vs straight. Let me try with the exact curly quotes from the fuzzy match.

The string to replace was not found in the file.

Thought Process

The fuzzy match shows straight quotes in the file. Let me read the file again to get the exact bytes.

Tool use: **read_file_v2** • Read file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

I see - line 116 shows "Root init.py" - the ** got converted. And the quotes in the file might be Unicode curly quotes. Let me try copying exactly from the read_file output - the quotes look like standard ASCII in the display. I'll try replacing line by line or use a shorter unique string.

Tool use: **edit_file_v2** • Edit file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

That created a mess - I left the old step 1 in. Let me remove the old implementation steps and the "(Removed old step 1.)" and fix the numbering.

The string to replace was not found in the file.

Thought Process

The file has curly quotes. Let me try with the exact characters - I'll try replacing just the erroneous line and the following old items.

Tool use: **edit_file_v2** • Edit file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

That's still wrong - I'm leaving duplicate/orphan content. Let me read the file and do one clean replacement to remove the leftover old steps and fix the closing sentence.

Tool use: **read_file_v2** • Read file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

I see - my replacement left "7. (Reserved.)" but the rest of the old step 1 was merged so now we have "7. (Reserved.) descendants(), pair discovery..." and then old steps 2-5 became 8-11. I need to remove lines 127-134 (the duplicate old steps and the old closing sentence) and change "7. (Reserved.)" to just the closing sentence.

The string to replace was not found in the file.

Thought Process

The fuzzy match shows curly double quotes in the file (""). Let me try using grep to get the exact content and then do a run_terminal_cmd to do the replacement with sed or just do multiple small search_replace operations. Actually, let me try replace_all with a simpler pattern - replace line 7 onwards.

Tool use: **edit_file_v2** • Edit file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

Let me try to remove from " `descendants()" through the end of the paragraph in chunks. First remove the tail of line 127.

Tool use: **edit_file_v2** • Edit file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

Now remove lines 8-11 and replace with the closing sentence. Let me read the file again to get exact content.

The string to replace was not found in the file.

Thought Process

Let me read the current state of the file again.

Tool use: **read_file_v2** • Read file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

So the "7." was replaced with empty, and now we have a blank line then "2. Add operator" - the numbering got broken (old steps 2-5 without the "8." "9." etc). I need to delete from line 128 (blank) through 134 and replace the closing sentence with the new one.

The string to replace was not found in the file.

Thought Process

The quotes in the file are definitely curly. Let me try writing the exact bytes - in the fuzzy match they show as " and ". I'll try copying from the fuzzy match output character by character. Actually, the simplest approach: use run_terminal_cmd to run a small Python or PowerShell script that does the replacement, or use a single-line search that's unique. Let me try replacing just "2. Add operator" with nothing and see if that's the right encoding - then do the rest in separate steps. Actually, I'll try with the curly quote character. In Unicode, the right double quote is U+201D. Let me try escaping or using a different approach - replace the closing sentence only first.

Trying a single-line replacement to remove the duplicate block:

Tool use: **ripgrep_raw_search**

Parameters:

{
  "pattern": "Migrated N pairs|canonical and makes",
  "path": "c:\\Users\\Nathan\\.cursor\\plans\\character_migrator_integration_cab95abc.plan.md",

      "matchCount": 2
    }
  ]
}

Status: completed

Thought Process

So the file does have the content. The issue is my search string uses straight quotes and the file has curly quotes. Let me try using run_terminal_cmd to replace. Actually, the run_terminal_cmd might have encoding issues too. Let me try search_replace with the Unicode curly quotes. In Python the right double quote is "\u201c" for left and "\u201d" for right. So "operator's" would be: " and '. Let me try replacing a smaller unique string that might be ascii - like "run_full_migration()" which is ascii.

The string to replace was not found in the file.

Thought Process

So the fuzzy match is not even that line - it's matching something else. The search_replace might be normalizing quotes. Let me try reading the raw file with a different approach - maybe the plan file is in the workspace. Let me try writing a small patch: read the full file, then write the full file with the duplicate block removed.

Tool use: **read_file_v2** • Read file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

I see - when I read the file, the quotes display as straight in the read_file output. So the file might have straight quotes. Let me try the replace again with the exact characters from the read - lines 128-134. I notice line 128 is blank and line 129 starts with "2. Add" - so there's no "7." in the current file. Let me try replacing the block from the blank line after step 6 through the end.

Tool use: **edit_file_v2** • Edit file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

Now I need to remove the "(Removed duplicate) 2. Add operator" through the end of the old closing sentence.

The string to replace was not found in the file.

Thought Process

The file might have different quote characters. Let me try deleting line by line. First delete "(Removed duplicate) 2. Add operator"

Tool use: **read_file_v2** • Read file: c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md

Thought Process

So we have the correct closing paragraph already at 128-129. I just need to remove lines 130-134. The read_file shows straight apostrophe in "spec's" and "operator's" - so maybe the issue is the double-quote character. Let me try replacing only the first line of the duplicate block to see - maybe the " and " are Unicode. I'll try using run_terminal_cmd with Python to do the replacement.

Thought Process

The link shows as (T:\AmazonCharacterTools) - in markdown the backslash might need to be escaped. It's fine for display. The plan is updated. Let me give the user a summary of what was added.

Summary of what was added to the plan:

1. Linked libraries

All linked library analysis is kept. Its UI (scan, list, search paths, find in folders, reload, open, relocate, etc.) is in its own dropdown/collapsible below the CharMig section.

2. Pair discovery and single-character migration

Only one character is migrated at a time (one pair per run).
Automatic mode: One pair is chosen by convention (*_Rigify / *_Rigify.001); user can pick from a list or use the first match.
Manual mode: The migrator has two fields – “Original character” and “Replacement character” – each with a picker that sets that field to the active armature’s name (or reference). Run migration uses exactly that (orig, rep) pair.

3. Collection context

Operators that change more than the armature (meshes, constraints on other objects) must be able to see the linked collection the armature belongs to. The plan calls for a helper that resolves the collection containing the armature (e.g. via users_collection or name matching) so descendants and related datablocks can be found and updated correctly.

4. Project structure (mirror AmazonCharacterTools)

Root: __init__.py, blender_manifest.toml
ui/: __init__.py, operators.py, panels.py, preferences.py (panels aggregate here; operators include migrator + library)
ops/: Feature logic (e.g. ops/migrator.py; library logic can live here too)
utils/: Helpers for descendants(armature) and collection containing armature

5. Files to touch and implementation order

“Files to touch” is rewritten as a bullet list for the new layout (utils, ops, ui, root, manifest).
Implementation order is: (1) Restructure into ui/ops/utils, (2) utils, (3) ops/migrator, (4) migrator props and operators, (5) UI with CharMig + Linked Libraries dropdown, (6) manifest and registration.

The plan file is at c:\Users\Nathan\.cursor\plans\character_migrator_integration_cab95abc.plan.md. A duplicate block at the end was removed so the implementation order and closing note are correct.

User

The user wants me to implement the Character Migrator Workflow Integration plan. Let me first check what todos exist and then work through them in order.

I'll need to:

Find the existing todos
Restructure the project (ui/, ops/, utils/) - move existing code
Add utils (descendants, collection helper)
Implement ops/migrator.py
Add migrator props and operators
UI: CharMig section + Linked Libraries dropdown
Update manifest and init

Let me start by listing the project structure and finding the todos.

I need to read the rest of operators.py to get all operators and understand the full register() list. Then I'll create the folder structure:

ui/ with operators.py, panels.py, preferences.py, __init__.py
ops/ with library logic (scan, find, etc.) and later migrator
utils/ with __init__.py

The plan says to move "existing panel/operator/prefs and library logic" into ui/ and ops/. So:

ui/panels.py: panel classes (split from current ui.py), and the panel draw logic
ui/preferences.py: DynamicLinkManagerPreferences, SearchPathItem (from ui.py)
ui/operators.py: all DLM operators - both library and (later) migrator. The library operators can stay as operators that call into ops if we put the heavy logic in ops, or we can keep the logic in ui/operators for now and just move the file.
ops/: put the scan logic in ops/library.py or similar so ui/operators just invokes it. Actually re-reading the plan: "Library: move current library-scan/relink logic into ops/ (e.g. one or more modules) and have ui/operators call into them." So I'll have ops/library.py with the scan/find/relink logic, and ui/operators will define the Operator classes that call into ops.library.

Let me read the full operators.py to see register() and all operator classes.

Status: completed

Thought Process

There are two register() blocks in operators.py - the first one at 392 only registers 2 classes, then more classes are defined, and the second register() at 702 registers all. So the first register() (lines 392-394) is dead code. I'll create the new structure:

utils/__init__.py - empty for now (will add descendants and collection helper in todo 2)
ops/__init__.py - empty
ops/library.py - I'll keep library logic in ui/operators for simplicity and fewer changes; the plan says "move current library-scan/relink logic into ops/" - I could either move the execute() bodies into ops.library and have operators call them, or keep operators as-is in ui/operators. To minimize breakage I'll keep the operator classes in ui/operators and not split the library logic into ops for now - we can do that refactor later. Actually the plan says "Library: move or re-export existing library operators here (or keep in ops and call from here)". So the operators stay in ui/operators, and we can put the heavy scan logic in ops/library.py. For the restructure, the minimal move is: create ui/, ops/, utils/, move the current ui.py content into ui/ (split into panels.py, preferences.py, and property groups/UIList can stay in panels or a separate file), move operators.py to ui/operators.py, then root __init__.py imports from .ui and registers. That way we don't have to split the library logic yet - we just reorganize files. Let me do that.

Actually re-reading again: "Create ui/, ops/, utils/; move existing panel/operator/prefs and library logic into ui/ and ops/". So:

ui/ gets: panels, preferences, operators (all the current UI and operator classes)
ops/ gets: library logic - the plan says "move current library-scan/relink logic into ops/". So the scan_linked_assets execute() logic could go to ops/library.py scan_linked_assets(context) and the operator just calls it. Same for find_libraries_in_folders. That would make the code cleaner. Let me do the file move first without splitting the library logic (so ops/ can be empty except __init__.py), then add utils, then add migrator. We can optionally move library logic to ops in a later step. The implementation order says "move existing panel/operator/prefs and library logic into ui/ and ops/" - so I'll put the library scan/find logic into ops/library.py.

Let me create:

utils/__init__.py (empty for now)
ops/__init__.py (empty)
ops/library.py - with scan and find_libraries logic (extracted from operators)
ui/__init__.py - exports OPERATOR_CLASSES, PANEL_CLASSES, preferences
ui/preferences.py - SearchPathItem, DynamicLinkManagerPreferences
ui/panels.py - PropertyGroups (LinkedDatablockItem, LinkedLibraryItem, DynamicLinkManagerProperties), DLM_UL_library_list, DLM_PT_main_panel. Note: the panel currently draws both CharMig (to be added) and Linked Libraries - for now I'll put the same content and add CharMig in step 5.
ui/operators.py - all operator classes; scan and find_libraries will call ops.library
Root __init__.py - import from .ui, register CLASSES, ensure_default_search_path, register scene props

I need to fix the package references: operators use package which in root is the addon name. When we move to ui/operators.py, package will be addon.ui. So we need the preferences to be looked up with the root package. In Blender addons, the root package is e.g. "dynamic_link_manager" (from manifest id or folder name). When we have from . import ui and ui has operators, the operators are still registered under the addon - and context.preferences.addons.get(package) in the root init gets the addon. If operators are in ui.operators, when they do context.preferences.addons.get(package), package will be "dynamic_link_manager.ui" or similar. So we need to use the root package for preferences. The root __init__.py has name which could be "dynamic_link_manager" or "main". So in ui/operators.py we should use the parent package for addon prefs. We can do context.preferences.addons.get(package.split('.')[0]) or store the root package in a constant. Let me check the manifest - the id is "dynamiclinkmanager". So the folder is likely Dynamic_Link_Manager and the module name might be dynamic_link_manager. So package in ui/operators will be "dynamic_link_manager.ui". So we need get(package.rsplit('.', 1)[0]) to get "dynamic_link_manager". I'll add that.

Now I need to create ui/preferences.py with the preferences and SearchPathItem. Then ui/panels.py with the property groups, UIList, and panel. Then ui/operators.py with all operators. The operators reference context.scene.dynamic_link_manager and context.preferences.addons.get(package). When operators live in ui.operators, package is "dynamic_link_manager.ui" (assuming the root package is dynamic_link_manager). So I need to get the root package. In Blender, the addon is typically loaded with a name - let me check the manifest: id = "dynamiclinkmanager". So the module name might be different. I'll use a helper: get the addon module from the operator's module's parent. So in ui/operators we can do: import sys _root = sys.modules.get(name.rsplit('.', 1)[0]) addon_name = _root.name if _root else package.rsplit('.', 1)[0] Then context.preferences.addons.get(addon_name). Actually in Blender, the addon's register() is called with name being the root module. So when we're in dynamic_link_manager.ui.operators, we want to get "dynamic_link_manager" for the addon lookup. So addon_name = package.rsplit('.', 1)[0]. That should work.

I'll create ui/properties.py with SearchPathItem, LinkedDatablockItem, LinkedLibraryItem, DynamicLinkManagerProperties. Then I need to add migrator props (original_character, replacement_character) to DynamicLinkManagerProperties - the plan says scene or wm props. I'll add them in step 4. For now just the existing props.

Tool use: **edit_file_v2** • Edit file: T:\Dynamic-Link-Manager\ui\properties.py

I used PointerProperty for original_character and replacement_character so the picker can set the active object. Now fix preferences to use the correct import - I had from . import properties, and SearchPathItem is in properties. Good. Now create panels.py with the UIList and the main panel. The panel will draw CharMig section first (mode, two fields + pickers, Run migration) and then Linked Libraries in a dropdown. I'll add the CharMig UI in step 5; for the restructure I'll just have the Linked Libraries content in a dropdown (same as now but inside a collapsible). Let me create panels.py with the current content reorganized: main panel with Linked Libraries in its own dropdown. CharMig will be added in todo 5.

Tool use: **edit_file_v2** • Edit file: T:\Dynamic-Link-Manager\ui\panels.py

Thought Process

I already added the CharMig UI and migrator props in properties. Now I need to create ui/operators.py with all the library operators plus the three migrator operators (run_character_migration, picker_original_character, picker_replacement_character). The library operators use context.scene.dynamic_link_manager and context.preferences.addons.get(package). When in ui.operators, package is "dynamic_link_manager.ui" so we need .rsplit(".", 1)[0] for the addon name. Let me use a variable at top of operators: ADDON_NAME = package.rsplit(".", 1)[0] if "." in package else package.

Creating ui/operators.py with library and migrator operators.

Tool use: **read_file_v2** • Read file: T:\Dynamic-Link-Manager\operators.py

Thought Process

I'll write the full ui/operators.py by copying the operators from the current operators.py and fixing the addon lookup to use the root package. I also need to add the three migrator operators. Let me write the file in chunks - first the imports and addon name, then all operator classes, then register/unregister. The register in the current file has duplicate register() - the first one only registers 2 classes. So the full list is: DLM_OT_replace_linked_asset, DLM_OT_scan_linked_assets, DLM_OT_find_libraries_in_folders, DLM_OT_open_linked_file, DLM_OT_add_search_path, DLM_OT_remove_search_path, DLM_OT_browse_search_path, DLM_OT_attempt_relink, DLM_OT_reload_libraries, DLM_OT_make_paths_relative, DLM_OT_make_paths_absolute, DLM_OT_relocate_single_library. Plus DLM_OT_run_character_migration, DLM_OT_picker_original_character, DLM_OT_picker_replacement_character. The migrator operators will call into ops.migrator when we implement it; for now I can add stubs that report "Not implemented" or I can implement the migrator in ops/migrator.py first. According to the implementation order I should do restructure first (so operators can be stubs), then utils, then ops/migrator, then wire up the operators. So for the restructure I'll add the three migrator operators as stubs that report "Run migration after migrator is implemented" or we could already have them call ops.migrator.run_full_migration once we create that module. Let me create ops/migrator.py in step 3 with the full logic, and in step 4 we "add migrator props and operators". So for step 1 (restructure) I'll add the picker and run operators as stubs that just report a message, and in step 3/4 we'll implement them. Actually re-reading the todo: step 4 is "Migrator props and operators" - so the operators are added in step 4. So for the restructure (step 1) I need the panel to not reference dlm.picker_original_character etc. until we have those operators. So I'll register stub operators in step 1 that do nothing or report INFO, and in step 4 we replace them with the real implementation. Or I can add the operator classes now and have them call ops.migrator.run_full_migration(context) which we'll implement in step 3 - so the operators exist but run_full_migration will be implemented in step 3. So in step 1 I add the three operator classes: run_character_migration calls ops.migrator.run_full_migration(context), picker_original sets context.scene.dynamic_link_manager.original_character = context.active_object, picker_replacement sets .replacement_character. So I need ops.migrator to exist and define run_full_migration. So the order is: 1) restructure with stub run_full_migration in ops/migrator (raises NotImplementedError or reports error), 2) utils, 3) ops/migrator full impl, 4) operators already have the three - just need to make sure they're registered. So for step 1 I'll create ops/migrator.py with a stub run_full_migration that returns an error message, and get_pair_manual/automatic that return (None, None). Then ui/operators has the three operators. Let me do that.

Adding a minimal ops/migrator.py stub so the restructure can register the migrator operators, then completing ui/operators.py.

get_pair_automatic has a bug: we're building seen_bases from two different patterns and might get inconsistent pairs. The spec says scan for *_Rigify and *_Rigify.001 with same base. So we should collect all armatures that match *_Rigify (no .001) as originals and *_Rigify.001 as replacements, then pair by base name. Let me fix that in step 3 when we implement fully. For now the stub is fine.

I referenced ..ops.library (scan_linked_assets, find_libraries_in_folders, attempt_relink). I need to create ops/library.py with those functions that take (context, report) and return {'FINISHED'} or {'CANCELLED'}. Let me extract the logic from the current operators.py into ops/library.py.

I need to create ops/library.py with:

scan_linked_assets(context, report) - the full scan logic, report is a method that takes (type, msg) e.g. self.report
find_libraries_in_folders(context, report)
attempt_relink(context, report)

The report in Blender is typically self.report({'INFO'}, "msg"). So the library functions will receive a callable that we can do report({'INFO'}, "msg"). So signature: def scan_linked_assets(context, report): ... report({'INFO'}, "Found ..."); return {'FINISHED'}.

Tool use: **edit_file_v2** • Edit file: T:\Dynamic-Link-Manager\ops\library.py

Thought Process

In ops/library.py I used package which will be "ops" or "dynamic_link_manager.ops" when imported from the addon. So package.rsplit(".", 1)[0] would give "dynamic_link_manager" when the addon is loaded as dynamic_link_manager. But when we're in ops/library.py, package is the package of that module - so it's the parent of "library", which is "ops". So we don't have the addon name in ops. We need to pass the addon name or get it differently. The ui/operators.py calls library.scan_linked_assets(context, self.report) - so the addon name isn't needed for scan. For find_libraries_in_folders and attempt_relink we need prefs. We get prefs via context.preferences.addons.get(ADDON_NAME). So we need the addon name in ops/library. The addon name could be passed as an argument, or we could get it from context - but context doesn't have the addon name. The standard way is to use a module that knows its root: e.g. in ui/operators we have ADDON_NAME. So the library functions could accept an optional addon_name parameter, or we could try common names. Actually the simplest is: in find_libraries_in_folders and attempt_relink, iterate context.preferences.addons and find the one that has .preferences.search_paths (our addon). Or we can pass addon_name from the operator. Let me pass addon_name from the operator to the library functions that need it. So find_libraries_in_folders(context, report, addon_name) and attempt_relink(context, report, addon_name). And in ui/operators we'll pass ADDON_NAME. Let me update ops/library.py to accept addon_name for find and attempt_relink. Actually a simpler approach: get the addon that has the search_paths. We can do: for name, addon in context.preferences.addons.items(): if getattr(getattr(addon, 'preferences', None), 'search_paths', None) is not None: prefs = addon.preferences; break. That's fragile. Cleaner: pass addon_name from the operator. So I'll add an optional addon_name to find_libraries_in_folders and attempt_relink. When called from the operator we pass ADDON_NAME. But the operator is in ui.operators and it imports ..ops.library - so from ui/operators.py the addon name is ADDON_NAME. So in the operator execute we call library.find_libraries_in_folders(context, self.report, ADDON_NAME). Same for attempt_relink. Let me update library.py to take addon_name as the third parameter and update the operators to pass it.

The addon's root package name: the folder is Dynamic-Link-Manager. In Blender, addons are typically loaded by folder name; the manifest has id = "dynamiclinkmanager". So the Python package could be "dynamic_link_manager" (with underscores) if the folder is renamed, or it might be "Dynamic_Link_Manager" or similar. Let me check - when you have a folder "Dynamic-Link-Manager", Blender might import it as a module - Python doesn't allow hyphens in module names, so the folder might be "dynamic_link_manager" or the addon might be loaded differently. I'll leave ADDON_NAME as package.rsplit(".", 1)[0] which from ui.operators gives the parent of "ui", i.e. the root package. So when the addon is loaded as "dynamic_link_manager", ui.package is "dynamic_link_manager.ui", and ADDON_NAME is "dynamic_link_manager". Good. Now create ui/__init__.py and update root __init__.py.

And bpy.types.Scene.dynamic_link_manager = PointerProperty(type=DynamicLinkManagerProperties). Let me list all classes that need registration from ui: properties: SearchPathItem, LinkedDatablockItem, LinkedLibraryItem, DynamicLinkManagerProperties. preferences: DynamicLinkManagerPreferences. panels: DLM_UL_library_list, DLM_PT_main_panel. operators: OPERATOR_CLASSES.

Now I need to remove or keep the old ui.py and operators.py at the root.

If we keep them, the root init would still import from .ui (the package), so the old ui.py and operators.py at root would be orphaned (root init no longer imports from .operators or .ui as modules - it imports from .ui the package). So we should delete the old ui.py and operators.py at the root to avoid confusion. Let me delete them.

Removing old root-level ui.py and operators.py, and fixing DynamicLinkManagerPreferences.bl_idname (it must be set at register).

Thought Process

When the addon is loaded, the root package could be "dynamic_link_manager" (if the folder is named that) or something else. The manifest says id = "dynamiclinkmanager". So the folder might be "dynamic_link_manager" to be a valid Python module. The preferences bl_idname should match the addon's module name so that Blender finds the preferences. So when the addon is loaded as name = "dynamic_link_manager", the preferences need bl_idname = "dynamic_link_manager". In ui/preferences.py, package is "dynamic_link_manager.ui", so rsplit(".", 1)[0] = "dynamic_link_manager". That's correct. Set bl_idname at register time in root init to name to be safe (like AmazonCharacterTools does with package). Let me set it in register(): DynamicLinkManagerPreferences.bl_idname = name

Blender addon folder name: often it's the folder name with hyphens replaced by underscores. So "Dynamic-Link-Manager" might be loaded as "Dynamic_Link_Manager" or "dynamic_link_manager" depending on the manifest. The manifest has id = "dynamiclinkmanager" - that's the addon id for the UI, not the Python module name. The Python module name is the folder name. So if the folder is "Dynamic-Link-Manager", Python might not load it as a module because of the hyphen. So the folder is likely "dynamic_link_manager" or similar. I'll leave as is. Let me run a quick test - we can't run Blender from here easily, but we can check for syntax/import errors. Let me also fix the panels to use the scene prop for migrator_mode - I used BoolProperty for "Automatic" - the plan says "Manual vs Automatic" so False = Manual, True = Automatic. And the panel draws "Automatic pair discovery" for the bool - so when True we use automatic. Good. Now mark todo 1 complete and move to todo 2 (utils).

Add to utils: 1) descendants(armature) - set of objects whose parent chain leads to that armature. 2) collection_containing_armature(armature) - the collection that contains the armature (e.g. root character collection). We can use armature.users_collection - often the character is in one collection. Return the first collection that contains the armature, or the one that matches the character "base" name. The plan says "e.g. by considering the armature's users_collection or a collection whose name matches the character base".

Todo 2 done. Todo 4 (migrator props and operators) is already done - we have the props in properties.py and the three operators. Todo 5 (UI) is already done - we have CharMig section and Linked Libraries dropdown in panels.py. So I'll mark 2 complete and move to 3 (ops/migrator full implementation).

Migrator props and operators (run migration, pickers)
UI: CharMig section + Linked Libraries dropdown
Update blender_manifest.toml and init registration

Thought Process

Implement the full migrator: steps 1-6 (step 7 inside step 4). I'll need to read the spec again for the exact logic. From the plan:

Step 1: Copy armature object attributes (location, rotation quaternion/euler, scale) from original to replacement. Step 2: Migrate NLA - copy tracks and strips, blend_type, extrapolation, frame_end, blend_in/out, repeat. Create animation_data on rep if missing. Step 3: Custom properties - copy pose-bone custom props, exclude _RNA_UI, rigify_type, rigify_parameters. Step 4: (a) On replacement, remove constraints that target another character's original. (b) Copy constraints from orig to rep: skip if target==orig; if target is other orig then set nc.target = other's rep; else keep. Copy name, mute, influence, subtarget, etc. (c) Trim rep constraints so count matches orig (remove from end). Step 5: Retarget relations - parents, constraint targets, Armature modifiers pointing at orig → rep; any object in file whose parent is orig → rep, etc. Step 6: Replacement base body - for each rep base body mesh (body+base in name, skinned to rep): if linked/override do override_create() only. Assign shape-key action.

orig_to_rep for a single pair is {orig: rep}. So when we have one pair, other_originals = [] for step 4 (no other character). So we only need to skip constraints that target orig (same character). Cross-character: if we had multiple pairs we'd have orig_to_rep mapping. For one pair, orig_to_rep = {orig: rep}. So "other character's original" = any key in orig_to_rep that is not orig = empty. So step 4 (a) remove from rep constraints where target in other_originals = no-op for single pair. (b) copy constraints, skip target==orig, if target in orig_to_rep set nc.target = orig_to_rep[target] (so we'd set rep when target is orig? No - we skip when target==orig. So when target is another character's orig we retarget. For single pair there is no "other" orig. So the logic is fine.)

Let me implement run_step_1 through run_step_6 and run_full_migration in ops/migrator.py. I'll use the utils.descendants and utils.collection_containing_armature.

Implementing the full migrator (steps 1–6) in ops/migrator.py.

Tool use: **read_file_v2** • Read file: a:\1 Amazon_Active_Projects\260206_PAE_2026\.specstory\history\2026-02-17_17-20Z-linked-library-override-resync-issue.md

Thought Process

I have the logic. For step 6 the spec says: if ob.data has library or override_library, call ob.data.override_create(). Then assign shape-key action - and we need to ensure shape_keys have animation_data (create if needed). Let me also note: step 6 says "if ob.data.shape_keys and ob.data.shape_keys.animation_data" - so we only assign action when animation_data exists. We might need to create animation_data on shape_keys if we want to assign an action. Let me check - we assign ob.data.shape_keys.animation_data.action = action. So if shape_keys exist but animation_data doesn't, we'd need shape_keys.animation_data_create() first. I'll add that.

Now write the full migrator. I need to handle the case where we have one pair - orig_to_rep = {orig: rep}. So "other" originals = empty. The cross-character retargeting only matters when there are multiple pairs; for one pair we still implement the logic (remove stale constraints targeting "other" orig - none; copy constraints with retarget if target in orig_to_rep - when target is orig we skip, so we never set nc.target = rep from that; when target is "other" orig we'd set to other rep - no other). So the code is the same.

Let me also fix get_pair_automatic - the current stub has a bug. We want to find all base names that have both Name_Rigify and Name_Rigify.001, then return the first pair. So: for obj in bpy.data.objects: if type != ARMATURE: continue if name ends with "_Rigify.001": base = name[:-len("_Rigify.001")], if base_Rigify exists, pair = (base_Rigify, obj) or: collect all origs (name has _Rigify and not .001), collect all reps (_Rigify.001). Match by base. bases = set() for o in armatures: if "_Rigify.001" in o.name: base = o.name.replace("_Rigify.001",""); orig = bpy.data.objects.get(base+"_Rigify"); if orig: yield (orig, o) or add to list Actually we need to return one pair. So build list of (orig, rep) for all bases that have both, then return the first.

Tool use: **edit_file_v2** • Edit file: T:\Dynamic-Link-Manager\ops\migrator.py

Thought Process

Step 6 base body: the spec says "mesh with 'body' and 'base' in name, skinned to rep". So we need to check that the mesh has an Armature modifier pointing at rep. I did that with the "for m in ob.modifiers: if m.type == ARMATURE and m.object == rep: break; else: continue" - so we only process meshes that have an armature modifier targeting rep. Good. But I used "name_lower" from ob.name and ob.data.name - the spec says "mesh with 'body' and 'base' in name". So the object name or the mesh data name should contain both. Good.

Fix the step 6 logic: we should only consider meshes that are skinned to rep (armature modifier with rep). So the loop should be: for ob in rep_descendants, if not MESH continue, check 'body' and 'base' in name (ob.name or ob.data.name), check that it has armature modifier with rep. Then override_create and action. I had the modifier check as "if we have modifiers and one is armature pointing to rep then we're good, else continue". So we skip if no armature modifier to rep. Good.

Let me double-check the run_step_4 retarget: when we copy a constraint and the target is in orig_to_rep, we set nc.target = orig_to_rep[t]. So when t is the other character's orig, we set to that character's rep. When we have only one pair, orig_to_rep = {orig: rep}, so "other" is empty, and we only skip when t == orig. So we never set nc.target = orig_to_rep[orig] because we skip when target == orig. Good.

Read lints and fix any issues. Also fix the migrator_mode in the panel - the plan says "Manual" vs "Automatic". So when migrator_mode is True we use automatic. The prop is "Automatic pair discovery" in the panel. Good.

Thought Process

ops/migrator uses "from ..utils" - when the addon is loaded, the root might be "dynamic_link_manager", so ..utils from ops is dynamic_link_manager.utils. Good. Let me verify the addon can be loaded - the folder name might be "Dynamic-Link-Manager" with a hyphen which isn't a valid Python module. Let me check the workspace path: T:\Dynamic-Link-Manager. So the folder is Dynamic-Link-Manager. In that case Python might not load it as a package because of the hyphen. Blender often uses the folder name; I've seen addons with hyphens in the folder - Blender might normalize it. I'll leave as is. If there are import errors the user would see them when enabling the addon.

Mark todo 3 complete. Todo 4 and 5 are already done (we have migrator props, operators, and UI). Todo 6: update blender_manifest.toml and ensure init registers migrator props - we already register the scene property and the props are on DynamicLinkManagerProperties. So we just need to update the manifest.

Thought Process

All todos are complete. Let me verify the panel uses migrator_mode correctly for automatic vs manual. In run_full_migration we do: use_auto = props and getattr(props, "migrator_mode", False). So when migrator_mode is True we use get_pair_automatic. When False we use get_pair_manual. The UI has "Automatic pair discovery" for the bool - so when checked we use automatic. Good.

One more thing: the panel draws the migrator section with two PointerProperty fields (original_character, replacement_character). In Blender, PointerProperty to Object with poll=lambda self, obj: obj.type == "ARMATURE" should show an object selector. The picker buttons set the active object to that prop. Good.

Let me also ensure that when we're in automatic mode we don't require the two fields to be set - we discover the pair. So run_full_migration is correct.

I'll double-check the ops/migrator import: from ..utils import descendants. The package structure is: dynamic_link_manager (or Dynamic_Link_Manager?), ui, ops, utils. So from ops.migrator, .. is the root, ..utils is the utils package. So we need the root package name to be something that has utils. When the addon is loaded, the root could be "dynamic_link_manager" if the folder is named that. If the folder is "Dynamic-Link-Manager", Blender might still load it - I'm not sure how Blender resolves that. Let me leave the import as is. If the addon folder is "dynamic_link_manager", then ops is dynamic_link_manager.ops and ..utils is dynamic_link_manager.utils. Good.

Let me run a quick test to see if there are any import errors when loading the addon. We can run Python and try to import the package. But the package name depends on the folder name. Let me check - in the workspace the path is T:\Dynamic-Link-Manager. So the folder name has a hyphen. When you install an addon in Blender, you typically zip the folder or point to the folder. The module name would be the folder name with hyphens - and Python doesn't allow hyphens in module names. So the addon might be installed as part of a path that gets added to sys.path and the module might be imported differently. I'll leave the code as is.

Summary for the user.

Summary of what was implemented:

1. Restructure (ui/, ops/, utils/)

Root __init__.py: Imports CLASSES from ui, sets DynamicLinkManagerPreferences.bl_idname = __name__, registers all classes and Scene.dynamic_link_manager, and adds ensure_default_search_path to load_post.
ui/: __init__.py (exports CLASSES), properties.py (SearchPathItem, LinkedDatablockItem, LinkedLibraryItem, DynamicLinkManagerProperties + migrator props: migrator_mode, original_character, replacement_character), preferences.py (DynamicLinkManagerPreferences), panels.py (DLM_UL_library_list, DLM_PT_main_panel), operators.py (all library operators + DLM_OT_run_character_migration, DLM_OT_picker_original_character, DLM_OT_picker_replacement_character).
ops/: __init__.py, library.py (scan_linked_assets, find_libraries_in_folders, attempt_relink), migrator.py (stub replaced with full implementation).
utils/: __init__.py with descendants(armature) and collection_containing_armature(armature).
Removed root ui.py and operators.py.

2. Utils

descendants(armature): returns objects whose parent chain includes the armature.
collection_containing_armature(armature): returns a collection that contains the armature (uses users_collection and name matching).

3. ops/migrator.py

get_pair_manual(context), get_pair_automatic(context).
Steps 1–6: copy attributes, NLA, custom props, bone constraints (with cross-character retarget via orig_to_rep), retarget relations, base body (library override only + shape-key action). Step 7 is included in step 4 (trim duplicate constraints).
run_full_migration(context): uses manual or automatic pair from migrator_mode, runs all steps, returns (True, msg) or (False, error_msg).

4. Migrator props and operators

Scene props: original_character, replacement_character (PointerProperty to Object), migrator_mode (BoolProperty).
Operators: run migration (calls run_full_migration), picker original, picker replacement (set active armature into the corresponding prop).

5. UI

Main panel: path buttons; CharMig box (Automatic pair discovery, Original + picker, Replacement + picker, Run migration); Linked Libraries box (scan, list, expand/collapse, reload, search paths, find in folders, selected library details).

6. Manifest and registration

blender_manifest.toml: tagline set to “Character migrator and linked library tools”.
Root __init__.py: registers all CLASSES and Scene.dynamic_link_manager.

Addon layout now mirrors AmazonCharacterTools (root __init__, ui/, ops/, utils/). Migrator runs one pair per run; manual pair from the two fields + pickers, or automatic from *_Rigify / *_Rigify.001. Linked library behaviour is unchanged and lives in the Linked Libraries section under CharMig.

User

make the linked libraries analysis box collapsible, and make it collapsed by default.

Agent (model default, mode Agent)

Thought Process

The user wants the Linked Libraries Analysis section to be collapsible and collapsed by default. I need to:

Add a property to control whether the Linked Libraries section is expanded or collapsed (separate from the existing linked_libraries_expanded which is for the library list inside)
Make the Linked Libraries Analysis box use a collapsible header so it can be collapsed/expanded
Set the default to collapsed

Let me check the current UI structure in panels.py.

Thought Process

I need to:

Add a new BoolProperty to DynamicLinkManagerProperties for the Linked Libraries Analysis box: e.g. linked_libraries_section_expanded with default=False (collapsed by default).
In panels.py, wrap the entire Linked Libraries Analysis box content in a collapsible. In Blender UI we use layout.prop(..., "property", text="", icon=icon, icon_only=True) to get a clickable disclosure triangle, then only draw the content when expanded. So the structure should be:
- A row with the disclosure triangle + "Linked Libraries Analysis" label
- When expanded, draw the rest (scan button, then the inner expanded list etc.)

I'll add linked_libraries_section_expanded with default=False.

Adding a property for the Linked Libraries section and making the panel use it so the section is collapsible and collapsed by default.

Done. The Linked Libraries Analysis box is now:

Collapsible via a disclosure triangle that toggles linked_libraries_section_expanded
Collapsed by default (default=False)
When collapsed, only the header row is shown (triangle + "Linked Libraries Analysis" + library count)
When expanded, the full content (scan button, inner list, search paths, etc.) is shown

Summary of changes:

1. ui/properties.py

Added linked_libraries_section_expanded (BoolProperty, default=False) to control whether the Linked Libraries Analysis section is open.

2. ui/panels.py

Replaced the plain "Linked Libraries Analysis" label with a row that has:
- A disclosure triangle bound to linked_libraries_section_expanded (collapsed = right, expanded = down).
- The "Linked Libraries Analysis" label.
- The library count (and missing count when relevant).
All content under that header (Scan button, library list, search paths, selected library details) is drawn only when linked_libraries_section_expanded is True.

The Linked Libraries Analysis block is now collapsible and starts collapsed by default. Users can click the triangle to expand it.

User

That's too low down, it should collapse at the main box.

Agent (model default, mode Agent)

Thought Process

The user wants the Linked Libraries Analysis to collapse at the "main box" level - meaning the entire box (the outer container) should be what collapses, not have the header inside the box with content below. So the collapse control should be on the box itself, and when collapsed we only show the box header (the row with the triangle and "Linked Libraries Analysis"), and the box shouldn't show any content inside when collapsed.

In Blender UI, a common pattern is to have a box, and the first row of the box is the header with the disclosure triangle. When collapsed, we don't draw the rest. So the "box" is still there but only the header row is visible. That's what I did - the box contains the header row and when expanded, the content. So the collapse IS at the box level - the whole box content (except the header row) is hidden when collapsed.

Maybe the user means the opposite: they want the Linked Libraries section to be higher up? "Too low down" might mean the collapse control is too far down the panel, or the visual hierarchy is wrong.

Re-reading: "it should collapse at the main box" - perhaps they mean the entire "Linked Libraries Analysis" should be one box that collapses as a unit, and the collapse toggle should be the main/only control for that box. Currently I have:

Box
- Row: [triangle] Linked Libraries Analysis (count)
- When expanded: scan button, then inner expanded list, etc.

So the box already collapses - when you click the triangle, the whole content inside the box (except the header row) collapses. Maybe the issue is that the header row is INSIDE the box, so visually the "box" still has a border around the header. Perhaps they want the box to literally not be drawn when collapsed - i.e. just a row with the triangle and label, and when expanded THEN we draw the box around the content? So when collapsed it would be: Row: [triangle] Linked Libraries Analysis (count) (no box) When expanded: Row: [triangle] Linked Libraries Analysis (count) Box: ... content ...

That way when collapsed there's no box at all - just the header row. So the "main box" only appears when expanded. Let me try that - when collapsed, draw only a row (no box). When expanded, draw the row then a box with all the content.

Making the collapse apply to the main box: when collapsed, show only the header row (no box); when expanded, show the header and a box containing all content.

Tool use: **read_file_v2** • Read file: T:\Dynamic-Link-Manager\ui\panels.py

Thought Process

I'll change it so:

When collapsed: only a row with the disclosure triangle + "Linked Libraries Analysis" + count (no box around it).
When expanded: the same header row, then layout.box() and put all the content inside that box.

So the "main box" only appears when the section is expanded.

Tool use: **edit_file_v2** • Edit file: T:\Dynamic-Link-Manager\ui\panels.py

Thought Process

Done. Now when collapsed: only the header row is shown (triangle + "Linked Libraries Analysis" + count) at the same level as the CharMig box - no box around it. When expanded: that same row, then a single main box that contains all the scan/list/search paths/selected library content. So the collapse is at the "main box" level - the box only appears when you expand.

Updated so the collapse is at the main box:

Collapsed (default): Only the header row is shown: disclosure triangle, “Linked Libraries Analysis”, and the library count. No box is drawn; it sits at the same level as the Character Migrator box.
Expanded: The same header row, then one main box that contains the scan button, library list, search paths, and selected library details.

So the whole Linked Libraries block is just the header until you expand it; the box only appears when expanded.

User

bpy.data.scenes["Scene"].dynamic_link_manager.linked_libraries_section_expanded is good, remove bpy.data.scenes["Scene"].dynamic_link_manager.linked_libraries_expanded

Agent (model default, mode Agent)

Thought Process

The user wants to:

Keep linked_libraries_section_expanded (the main section collapse)
Remove linked_libraries_expanded (the inner "Linked Libraries" list expand/collapse)

So I need to remove the property and change the UI so that when the section is expanded, the library list and everything inside is always shown (no inner collapse). I'll remove the linked_libraries_expanded property and flatten the UI so the list is always visible when the section is expanded.

Good - the properties file is correct. linked_libraries_expanded was removed and linked_libraries_section_expanded is intact. Done.

ui/properties.py

Removed the linked_libraries_expanded property.
Left linked_libraries_section_expanded as-is.

ui/panels.py

When the Linked Libraries section is expanded, the library list, reload button, search paths, and selected library details are shown directly (no inner expand/collapse row or linked_libraries_expanded usage).

Only the main section toggle linked_libraries_section_expanded remains; the inner “Linked Libraries” expand is gone.

User

I'll figure out bpy.ops.dlm.run_character_migration() later. For now, I want every single step to be its own button, its own operator. bpy.ops.dlm.run_character_migration() should invoke every single operator that can also be invoked individually.

Agent (model default, mode Agent)

Thought Process

The user wants to split the character migration into individual step operators, each with its own button. Then run_character_migration should simply invoke all of those operators in sequence (so it can be run as one action, but each step is also available individually).

Let me check the current migrator steps and how run_full_migration works, so I can plan the operators and UI.

Tool use: **read_file_v2** • Read file: T:\Dynamic-Link-Manager\ui\panels.py

Thought Process

There are 6 steps in the migrator (step 7 is inside step 4). So I need:

DLM_OT_migrator_step_1 - Copy attributes (location, rotation, scale)
DLM_OT_migrator_step_2 - Migrate NLA
DLM_OT_migrator_step_3 - Custom properties
DLM_OT_migrator_step_4 - Bone constraints (includes step 7 trim)
DLM_OT_migrator_step_5 - Retarget relations
DLM_OT_migrator_step_6 - Replacement base body

Each operator will:

Resolve the pair (manual or automatic from props)
Call the corresponding run_step_N from ops.migrator
Report success/failure

For steps 4 and 5 they need orig_to_rep (dict) and rep_descendants. So each step operator needs to get (orig, rep) then build orig_to_rep = {orig: rep} and rep_descendants = descendants(rep) when needed.

run_character_migration will then just execute the 6 operators in order via bpy.ops.dlm.migrator_step_1(), ... step_6(). We need to be careful: calling bpy.ops from Python passes context; the operators need to get the pair from context.scene.dynamic_link_manager each time. So run_character_migration can do:

bpy.ops.dlm.migrator_step_1() bpy.ops.dlm.migrator_step_2() ... (or we could keep calling the run_step_N functions directly from run_character_migration to avoid 6 operator invocations - but the user said "invoke every single operator". So they want run_character_migration to literally call the operators. So each operator is a wrapper that gets pair, calls run_step_N. And run_character_migration does for i in 1..6: bpy.ops.dlm.migrator_step_i(). We need to pass context - in Blender, when you call bpy.ops.x from another operator's execute(), you use context. So it would be context.ops.dlm.migrator_step_1() or we need to get the right context. Actually in Blender, from an operator's execute we do bpy.ops.dlm.migrator_step_1() - that uses the current context. So we're good.

Plan:

Add 6 new operators in ui/operators.py: DLM_OT_migrator_step_1 through DLM_OT_migrator_step_6. Each gets (orig, rep) from context (manual or automatic), then calls the corresponding run_step_N from ops.migrator. Steps 4 and 5 need orig_to_rep and rep_descendants - they get that from orig, rep (orig_to_rep = {orig: rep}, rep_descendants = descendants(rep)).
Change DLM_OT_run_character_migration execute() to call bpy.ops.dlm.migrator_step_1() through bpy.ops.dlm.migrator_step_6() in sequence. If any returns CANCELLED, report and return CANCELLED.
In ui/panels.py, add 6 buttons for the 6 steps (and keep "Run migration" which runs all).

Let me also check the migrator for run_step_5 and run_step_6 signatures.

Tool use: **read_file_v2** • Read file: T:\Dynamic-Link-Manager\ops\migrator.py

Thought Process

I have the full picture. Each step operator needs to resolve the pair once; steps 4, 5, 6 need orig_to_rep and/or rep_descendants. So either each operator resolves the pair (and steps 4/5/6 also compute orig_to_rep and rep_descendants), or we have a small helper that returns (orig, rep, orig_to_rep, rep_descendants) and each operator uses that. I'll have each operator get the pair via the same logic as run_full_migration (manual/auto from props), then steps 4 and 5 also compute orig_to_rep = {orig: rep} and rep_descendants = descendants(rep).

Plan:

ui/operators.py: Add 6 operators (DLM_OT_migrator_step_1 … DLM_OT_migrator_step_6). Each in execute(): resolve (orig, rep) using migrator.get_pair_manual/automatic and props.migrator_mode; if no pair, report and CANCELLED. Then call the corresponding run_step_N. Steps 4 and 5 need orig_to_rep = {orig: rep} and rep_descendants = descendants(rep) from utils. Add these to OPERATOR_CLASSES.
DLM_OT_run_character_migration: In execute(), call in order: bpy.ops.dlm.migrator_step_1(), migrator_step_2(), ... migrator_step_6(). Use context. If any returns {'CANCELLED'}, report and return CANCELLED; else report success and FINISHED.
ui/panels.py: In the CharMig box, add a row with 6 buttons (Step 1: Copy attributes, Step 2: NLA, etc.) and keep the "Run migration" button (or put it first). Layout could be: Run migration (full); then Step 1, Step 2, ... Step 6 as individual buttons.

Creating the plan.

Creating a plan for per-step operators and wiring the full migration to invoke them.

Tool use: **create_plan**

Parameters:

{
  "plan": "# Per-step character migrator operators\n\n## Goal\n\n- **Six step operators:** Step 1 (copy attributes), Step 2 (NLA), Step 3 (custom props), Step 4 (bone constraints + trim), Step 5 (retarget relations), Step 6 (base body override + shape-key action). Each is invokable on its own via a button.\n- **Run migration:** &#96;bpy.ops.dlm.run_character_migration()&#96; should invoke these six operators in order (no direct call to &#96;run_full_migration&#96; logic); it remains the “run all” action.\n\n## 1. New operators in [ui/operators.py](T:\\Dynamic-Link-Manager\\ui\\operators.py)\n\nAdd six operators, e.g. &#96;DLM_OT_migrator_step_1&#96; … &#96;DLM_OT_migrator_step_6&#96;, with &#96;bl_idname&#96; like &#96;dlm.migrator_step_1&#96; … &#96;dlm.migrator_step_6&#96;.\n\n**Shared behavior in each:**\n\n- In &#96;execute(self, context)&#96;:\n  - Get pair from scene: &#96;props = context.scene.dynamic_link_manager&#96;, &#96;use_auto = props.migrator_mode&#96;, then &#96;orig, rep = get_pair_automatic(context) if use_auto else get_pair_manual(context)&#96; (using existing &#96;get_pair_manual&#96; / &#96;get_pair_automatic&#96; from [ops/migrator.py](T:\\Dynamic-Link-Manager\\ops\\migrator.py)).\n  - If &#96;not orig or not rep&#96; or &#96;orig == rep&#96;: &#96;self.report({'ERROR'}, ...)&#96;, &#96;return {'CANCELLED'}&#96;.\n  - Call the corresponding &#96;run_step_N(...)&#96; from &#96;ops.migrator&#96; (and for steps 4 and 5, also compute &#96;orig_to_rep = {orig: rep}&#96; and &#96;rep_descendants = descendants(rep)&#96; using [utils](T:\\Dynamic-Link-Manager\\utils\\__init__.py)).\n- Use &#96;bl_options = {'REGISTER', 'UNDO'}&#96; where appropriate (all steps modify data).\n- Keep logic in [ops/migrator.py](T:\\Dynamic-Link-Manager\\ops\\migrator.py) as-is; operators only resolve the pair and call &#96;run_step_1&#96; … &#96;run_step_6&#96;.\n\n**Step-specific calls:**\n\n| Operator            | Calls |\n|---------------------|--------|\n| migrator_step_1     | &#96;run_step_1(orig, rep)&#96; |\n| migrator_step_2     | &#96;run_step_2(orig, rep)&#96; |\n| migrator_step_3     | &#96;run_step_3(orig, rep)&#96; |\n| migrator_step_4     | &#96;orig_to_rep = {orig: rep}&#96;, &#96;run_step_4(orig, rep, orig_to_rep)&#96; |\n| migrator_step_5     | &#96;rep_descendants = descendants(rep)&#96;, &#96;orig_to_rep = {orig: rep}&#96;, &#96;run_step_5(orig, rep, rep_descendants, orig_to_rep)&#96; |\n| migrator_step_6     | &#96;rep_descendants = descendants(rep)&#96;, &#96;run_step_6(orig, rep, rep_descendants)&#96; |\n\nWrap each &#96;run_step_N&#96; call in try/except; on exception report and return &#96;{'CANCELLED'}&#96;. On success report a short message and return &#96;{'FINISHED'}&#96;.\n\nAppend the six classes to &#96;OPERATOR_CLASSES&#96;.\n\n## 2. Change run_character_migration in [ui/operators.py](T:\\Dynamic-Link-Manager\\ui\\operators.py)\n\nIn &#96;DLM_OT_run_character_migration.execute(self, context)&#96;:\n\n- Do **not** call &#96;run_full_migration(context)&#96;.\n- Call in order:  \n  &#96;bpy.ops.dlm.migrator_step_1()&#96;, &#96;bpy.ops.dlm.migrator_step_2()&#96;, … &#96;bpy.ops.dlm.migrator_step_6()&#96;.\n- Use the same &#96;context&#96; (e.g. pass it if the Blender API requires it; typically &#96;bpy.ops.dlm.migrator_step_1()&#96; uses the current context).\n- If any of these returns &#96;{'CANCELLED'}&#96;, report which step failed and return &#96;{'CANCELLED'}&#96;.\n- If all return &#96;{'FINISHED'}&#96;, report success (e.g. “Migration complete”) and return &#96;{'FINISHED'}&#96;.\n\nSo the full migration is exactly “invoke the six step operators in sequence.”\n\n## 3. UI in [ui/panels.py](T:\\Dynamic-Link-Manager\\ui\\panels.py)\n\nIn the Character Migrator box, after the pair fields and pickers:\n\n- Keep one **“Run migration”** button that calls &#96;dlm.run_character_migration&#96; (runs all steps).\n- Add **six buttons**, one per step, e.g.:\n  - “Step 1: Copy attributes” → &#96;dlm.migrator_step_1&#96;\n  - “Step 2: Migrate NLA” → &#96;dlm.migrator_step_2&#96;\n  - “Step 3: Custom properties” → &#96;dlm.migrator_step_3&#96;\n  - “Step 4: Bone constraints” → &#96;dlm.migrator_step_4&#96;\n  - “Step 5: Retarget relations” → &#96;dlm.migrator_step_5&#96;\n  - “Step 6: Base body override” → &#96;dlm.migrator_step_6&#96;\n\nLayout can be one row for “Run migration” and then a row or column of the six step buttons (or two rows of three), depending on space.\n\n## 4. No changes to [ops/migrator.py](T:\\Dynamic-Link-Manager\\ops\\migrator.py)\n\nKeep &#96;get_pair_manual&#96;, &#96;get_pair_automatic&#96;, &#96;run_step_1&#96; … &#96;run_step_6&#96;, and &#96;run_full_migration&#96;. The add-on will use the step functions from the new operators and will use “run all” by invoking the six operators; &#96;run_full_migration&#96; can remain for any future or script use but is not required for the UI.\n\n## Summary\n\n- **New:** 6 operators in &#96;ui/operators.py&#96;, each resolving the pair and calling one &#96;run_step_N&#96;.\n- **Changed:** &#96;DLM_OT_run_character_migration&#96; only invokes those 6 operators in order.\n- **New UI:** 6 step buttons in the CharMig panel plus the existing “Run migration” button.\n- **Unchanged:** &#96;ops/migrator.py&#96;, pair resolution and step logic.\n",

each step should be named after the step from the original specstory.

Agent (model default, mode Agent)

Thought Process

The user wants the step operators (and presumably their UI labels) to be named after the steps from the original spec story. Let me check the plan and the spec story for the exact step names used there.

From the plan file I created and the earlier context, the spec story steps were:

Copy attributes (location, rotation, scale)
Migrate NLA
Custom properties
Bone constraints (with cross-character retarget, trim duplicates)
Retarget relations
Replacement base body (library override + shape-key action)
(inside 4) Remove duplicate constraints

The spec story transcript might use slightly different wording. Let me search for how the steps were referred to in the spec.

Status: completed

Thought Process

From the spec story the steps are referred to as:

Step 1: Copy attributes
Step 2: NLA (migrate NLA / mirror tracks)
Step 3: Custom properties (pose-bone custom properties)
Step 4: Bone constraints (copy and retarget)
Step 5: Retarget relations (parent, constraint target, Armature modifier)
Step 6: Replacement base body (override + shape-key action)
Step 7: (inside 4) Remove duplicate constraints

The plan document (character_migrator_integration) had a table: | 1 | Copy armature object attributes: location, rotation (quaternion/euler), scale from original to replacement. | | 2 | Migrate NLA: copy tracks and strips... | | 3 | Custom properties: copy pose-bone custom props... | | 4 | Bone constraints: (a) On replacement, remove... (b) Copy constraints... (c) Trim... | | 5 | Retarget relations: ... | | 6 | Replacement base body: ... | | 7 | Implemented inside step 4: remove duplicate constraints |

So the canonical names from the spec/plan are:

Copy attributes (or "Copy armature object attributes")
Migrate NLA
Custom properties
Bone constraints
Retarget relations
Replacement base body

For operator bl_idname we need valid identifiers (lowercase, underscores). So:

dlm.migrator_copy_attributes
dlm.migrator_migrate_nla
dlm.migrator_custom_properties
dlm.migrator_bone_constraints
dlm.migrator_retarget_relations
dlm.migrator_replacement_base_body

And bl_label can be the human-readable spec name:

"Copy attributes"
"Migrate NLA"
"Custom properties"
"Bone constraints"
"Retarget relations"
"Replacement base body"

I'll update the plan file to use these names.

Tool use: **read_file_v2** • Read file: c:\Users\Nathan\.cursor\plans\per-step_migrator_operators_4986daf6.plan.md

Thought Process

I need to update the plan so that each step is named after the spec story. From the spec story the steps are:

Copy attributes
Migrate NLA (or "NLA")
Custom properties
Bone constraints
Retarget relations
Replacement base body

So the operator bl_idnames should be based on these names (snake_case for id):

dlm.migrator_copy_attributes
dlm.migrator_migrate_nla
dlm.migrator_custom_properties
dlm.migrator_bone_constraints
dlm.migrator_retarget_relations
dlm.migrator_replacement_base_body

And bl_label / button text:

Copy attributes
Migrate NLA
Custom properties
Bone constraints
Retarget relations
Replacement base body

I'll update the plan file to use these names throughout (operator ids, class names, and UI labels).

Updating the plan to name each step after the spec story (Copy attributes, Migrate NLA, Custom properties, Bone constraints, Retarget relations, Replacement base body).

Thought Process

Plan is updated. Summary for the user.

Summary of updates to the plan:

Step names (from spec story)
Each step is now identified by the spec story name, and the plan uses these consistently:

Step	bl_idname	bl_label / button
1	`dlm.migrator_copy_attributes`	Copy attributes
2	`dlm.migrator_migrate_nla`	Migrate NLA
3	`dlm.migrator_custom_properties`	Custom properties
4	`dlm.migrator_bone_constraints`	Bone constraints
5	`dlm.migrator_retarget_relations`	Retarget relations
6	`dlm.migrator_replacement_base_body`	Replacement base body

Plan changes

Added a “Step names (from spec story)” section with the table above.
Replaced generic migrator_step_1 … migrator_step_6 with these ids and labels everywhere (operator classes, bl_idname, bl_label, UI buttons).
run_character_migration is specified to call bpy.ops.dlm.migrator_copy_attributes(), bpy.ops.dlm.migrator_migrate_nla(), etc., in that order.
Fixed the utils link typo (utils__init__.py → utils/__init__.py).

So each step is named after the original spec story (Copy attributes, Migrate NLA, Custom properties, Bone constraints, Retarget relations, Replacement base body) in both code and UI.

User

Implement the plan as specified, it is attached for your reference. Do NOT edit the plan file itself.

To-do's from the plan have already been created. Do not create them again. Mark them as in_progress as you work, starting with the first one. Don't stop until you have completed all the to-dos.

Agent (model default, mode Agent)

Thought Process

The user wants me to implement the per-step migrator operators plan. Let me check the todos and then implement:

Add six operators in ui/operators.py with the spec story names (copy_attributes, migrate_nla, custom_properties, bone_constraints, retarget_relations, replacement_base_body)
Change run_character_migration to invoke those six operators in order
Add six buttons in ui/panels.py

I'll start by reading the current operators and panels to implement the changes.

Tool use: **todo_write** • Todo List

[-] Add six migrator step operators in ui/operators.py
Change run_character_migration to invoke six operators
Add six step buttons in CharMig panel
Migrator props and operators (run migration, pickers)
UI: CharMig section + Linked Libraries dropdown
Update blender_manifest.toml and init registration

Tool use: **read_file_v2** • Read file: T:\Dynamic-Link-Manager\ui\operators.py

Thought Process

I need to:

Add a helper that gets (orig, rep) from context (used by all step operators)
Add six operator classes: DLM_OT_migrator_copy_attributes, DLM_OT_migrator_migrate_nla, DLM_OT_migrator_custom_properties, DLM_OT_migrator_bone_constraints, DLM_OT_migrator_retarget_relations, DLM_OT_migrator_replacement_base_body
Change DLM_OT_run_character_migration to call those six operators in order
Add the six to OPERATOR_CLASSES
Update panels to add the six buttons

Let me implement the six operators. Each one:

Gets props, use_auto = props.migrator_mode, orig, rep = get_pair_automatic if use_auto else get_pair_manual
If not orig or not rep or orig == rep: report error, return CANCELLED
Try: call run_step_N (with orig_to_rep and rep_descendants for steps 4, 5, 6), report success, return FINISHED
Except: report exception, return CANCELLED

Adding the six step operators and a shared pair-resolve helper:

Tool use: **edit_file_v2** • Edit file: T:\Dynamic-Link-Manager\ui\operators.py

Thought Process

I made a mistake - I left duplicate/broken code in run_character_migration. There was a loop that called migrator_copy_attributes 6 times, then I added the op_id_to_call dict and another loop. Let me fix run_character_migration to only have the single loop that calls each operator by id.

Fixing run_character_migration: removing the duplicate loop and incorrect call.

Tool use: **edit_file_v2** • Edit file: T:\Dynamic-Link-Manager\ui\operators.py

Now add the six operator classes to OPERATOR_CLASSES.
