-# Melvile Tools: notes for Claude
-
-Blender add-on (Blender 5.2) for the Melvile pipeline at Walking The Dog: Sanity Check,
-Rename, Shot Manager and Scene Manager panels in the 3D View sidebar (WTD tab). `README.md`
-is the user guide: keep it up to date with every user-visible change.
-
-## Layout and conventions
-
-- `config.py`: every production value (prefixes, formats, patterns, modes). Values are
-  read at run time (`config.X`, never copied at import) because a studio JSON file can
-  override them (add-on preferences "Config Override", or `WTD_SANITY_CONFIG`).
-  New tunable values go here, with a comment, and in the README's Configuration table.
-- `ui/panel.py`: all panels. Operators live with their tool (`rename.py`,
-  `shot_viewer.py`, `scene_manager/`, `ui/operators.py` for the Sanity Check).
-- `checks/`: sanity checks, auto-registered (see README > For developers).
-- `__init__.py` deletes cached submodules on reload, so Reload Scripts picks up every file.
-- Versions: `blender_manifest.toml` and `bl_info` in `__init__.py` (keep both in sync).
-- Style: match the surrounding code; short docstrings, few comments, no heavy abstractions.
-
-## Working with the user
-
-- Commits: when asked, create a branch from `master`, commit there (end with the
-  Co-Authored-By line), and give the user the merge / push / branch-delete commands:
-  they run them themselves. Only commit straight on `master` when told to.
-- Real Blender API facts beat memory: probe in headless Blender before relying on an API.
-
-## Testing
-
-Blender binary: macOS `/Applications/Blender.app/Contents/MacOS/Blender`, Windows
-`blender.exe` from the install folder. Import the add-on in tests by putting the folder
-that contains this repo on `sys.path` and importing the repo folder name (see
-`dev/test_scene_manager.py`).
-
-- Headless: `blender -b --factory-startup --python-exit-code 1 --python <script> -- <args>`.
-  Timers do not run in background mode: pump background jobs by hand
-  (`scene_manager.ipc._poll()`).
-- UI: run Blender with a window (`--factory-startup <file.blend> --python <script>`, a
-  .blend argument avoids the splash), drive it with `bpy.app.timers`, take screenshots with
-  `bpy.ops.screen.screenshot_area`, quit with `bpy.ops.wm.quit_blender()`. A sidebar tab
-  (`region.active_panel_category`) can only be set once the region has been drawn.
-- Scene Manager without Libreflow (`dev/`):
-  1. `blender -b --factory-startup --python dev/make_test_assets.py -- <workdir>`
-  2. `python dev/fake_libreflow.py <workdir>` (keep running; restart for a clean state)
-  3. `blender -b --factory-startup --python-exit-code 1 --python dev/test_scene_manager.py -- <workdir>`
-     (71 checks, "All checks passed"). `/_test/publish` and `/_test/download` simulate a new
-     publish and a requested revision reaching this site.
-  The fake server follows the real `wtdcmds` replies; check them against the real
-  Libreflow when one is available.
-
-## External pieces
-
-- Libreflow `wtdcmds` extension (commands used by the Scene Manager), on the share:
-  `WG/_Dev/GIT/ndemaerschalk/_MELVILE/libreflow_dev_utils/dev/src/wtdcmds/`
-  (`src/libreflow/extensions/wtdcmds/wtd_cmds.py`, `BLENDER_ADDON_BRIEF.md`).
-  Server address/token: `~/.kabaret/ipc/server.json` (config `LIBREFLOW_SERVER_FILE`).
-- Add Camera Rigs extension: `bpy.ops.object.build_camera_rig(mode=...)` builds the
-  Shot Manager cameras. It finds its rigs by the `rig_id` custom property, not by name.
-- `tools_ops.py` "Get Oid" uses the separate kabaret Blender client (`bpy.ops.kabaret.cmds_call`).
-
-## Design notes (found by testing)
-
-- Shot Manager: shots are timeline markers bound to cameras, in one scene. Setting
-  `scene.frame_current` does not switch the camera (only `frame_set` does): set
-  `scene.camera` explicitly.
-- Scene Manager: tags live on `bpy.types.Library` only. Library overrides lose custom
-  properties when they resync, so instances are traced back to their library (empty →
-  `instance_collection.library`, override → `override_library.reference.library`).
-- `library.reload()` invalidates every Python reference to linked and override data:
-  look IDs up again afterwards. In Blender 5.2 it also replaces the Library itself (renamed
-  after its file, custom properties gone): `library.update()` finds it by path and restores
-  the name and tags.
-- Removing a library leaves the libraries it linked indirectly (e.g. Blender's
-  `geometry_nodes_essentials.blend`): `remove_unused_libraries()` drops the ones whose data
-  is no longer used, never a managed library.
-- LODs are child collections of the asset collection (`COL_{asset}_LOD{lod}`, any name,
-  ordered by `SCENE_MANAGER_LODS`, then numbers, then names; the first is the default). Overrides
-  switch by `hide_viewport`/`hide_render` on the LOD override collections: Blender stores
-  them as override properties (kept through save, reload and resync) and hidden LODs are
-  not evaluated. Collection instances instance the LOD collection itself. A second override's
-  collections are renamed (`.001`): match LODs on `override_library.reference.name`.
-- "Shot Manager" is the user-facing name of what the code calls `shot_viewer`
-  (module, operators, `SHOT_VIEWER_*` config keys kept for existing override files).
-- Background requests (`scene_manager.ipc.run`) hand results back through a timer;
-  in callbacks, find scenes by name (`bpy.context.scene` is not reliable in timers).
-
-## Real Libreflow (first run, 2026-10-27)
-
-- Kitsu asset types: `main_character`, `secondary_character`, `tertiary_character`,
-  `main_props`, `secondary_props`, `set_props`, `vehicles`, `bg_location`, `bg_set`,
-  `skies`, `setdress_bank`. The fake server uses the same names.
-- Paths come back as Windows paths with backslashes; `comment` can be `null`.
-- Set dressing publishes (`setdress_low`) hold a whole layout scene: the set is the
-  `environments` collection, next to `lights`, `cameras`, `characters`, `_unused`.
-- Tested live: connection, context, casting, load (instance and override), version switch
-  and update, remove, assetize errors, one request (`car_paul` modeling.blend v001 →
-  `Requested`). Not tested: an actual assetize publish (it writes to production).
-  New wtdcmds commands need every Libreflow session restarted (a running one keeps the
-  old code and answers 404).
-- Load Publish (2026-10-28) uses only existing commands (`wtd_list_assets`,
-  `wtd_get_asset_files`, `wtd_get_revisions`): 309 assets in ~0.1 s, live-tested on
-  `car_paul` (loaded twice: `car_paul_01`, `car_paul_02`).
-- `/melvile/films/melvile` has no sequences or shots in Libreflow yet; `melvile_test` has 9.
-- Deployed Libreflow (Overseer launcher): wtdcmds must be an "extension" entry, so the
-  launcher adds `libreflow.extensions.wtdcmds:install_extensions` to
-  `KABARET_FLOW_EXT_INSTALLERS`; the package name must stay `libreflow.extensions.wtdcmds`.
-  The launcher only rebuilds its env when the project config changes: "Force update".
-
-## Open points
-
-- Override vs instance per asset type (`SCENE_MANAGER_LINK_MODES`), and the file patterns
-  of sets (`setdress_low` seen on one asset only): confirm with production.
-- The server picks the first file matching a pattern even when it is not on this site,
-  while another matching file is (e.g. `car_paul`: `modeling/modeling.blend` v001 not
-  available, `modeling/tes_modeling.blend` v002 available).
-- Values marked TODO in `config.py` wait for production specs.
