Bonsai: custom display names for links

Each link row draws an editable display_name (double-click to rename)
with the file path as placeholder while unset, so several links of the
same file can be told apart. The name persists in the same Description
JSON blob as the filter and loaded state (new name key, written at
save time and by reload_link), restores on project open, and plain
legacy strings still decode unchanged. Decode tests updated to the
four-tuple with a name round-trip case.

-Docker build environment
-========================
-
-This is a small utility to make it easy to compile a perfect `_ifcopenshell_wrapper.cpython-*-x86_64-linux-gnu.so`
-files.
-
-The reason for this tool is that I was trying to follow the web page directions, and my build was behaving differently
-to the release builds. Eventually I concluded that the differences between toolchains on the RHEL based rocky9 image
-and Ubuntu were just too great. Getting the build setup was already a lot of trial and error, so I thought I'd spend
-more time trying to reuse the github actions that perform the build, using a utility called `act`. I learnt a lot, in
-particular how much time, energy, and bandwidth Github waste. I also realised I was most of the way to a regular docker
-setup anyway, so I might as well just do that. So I've deconstructed all the github action steps, and turned it into
-a local docker build environment that uses the exact same base, tools, libraries, and build command/flags etc.
-
-Right now a Github action will:
-- launch the rocky9 base
-- upgrade all the packages
-- install a bunch of extra tools
-- do a recursive checkout of your repo
-- checkout the build repository
-- unpack dependencies
-- run the build script, making all python versions (5? right now I think)
-- create the .zip release files
-
-And it does _all_ of that _every_ time. This is not a fault of the action writers - it's just how Github seems to work.
-
-These dockers tools do the following differently, and it's actually a bit more powerful too:
-- build the base image once.
-- update the packages once.
-- install the extra tools once.
-- the repository is the one on your host, that gets bind mounted in the container as the working directory.
-- by adding an environment variable to .env, restricts to compiling for just a single python version.
-- when the build is finished the created files are right there under your local repositry (but not added to git) for
-  ease of access
-- each repository can have it's own build environment container.
-- the image is shared between those environments.
-- the containers share the ccache, so additional envs should get a helping hand.
-- it has a simple set of user friendly commands to drive it all.
-
-For example:
-``` bash
-# To see the commands (a superset of docker compose commands)
-./ifcos_env
-
-# Enable autocomplete of commands
-source .ifcos_env
-
-# First time commands
-./ifcos_env create
-./ifcos_env up
-./ifcos_env build
-
-# install and test library
-# find an issue
-# edit code
-./ifcos_env build
-
-# and so on. When done stop and optionally delete the container
-./ifcos_env stop
-./ifcos_env remove
-```
-
-To limit the build to one python version just add
-``` bash
-PY_TGT=py-311
-```
-or whichever version your Blender requires.

-You might see UNIQUE_ID in the .env file too. This keeps containers for separate folders, separate.
-
-System requirements
-1. Linux-x64 only at this time.
-2. Docker and docker-compose need to be installed.
-3. Have a good amount of disk space. (image is in /var (typically the root partition) and will be about 1.7 GB)
-4. The build action will create about 10GB in your repository folder. Make sure this partition is spacious
-   particularly if you intent on having multiple clones building.
-5. ... I think that covers most of it.

-name: ifcopenshell-docker-build
-description: >-
-  Build a real ifcopenshell_wrapper (.so + .py) and IfcConvert locally via
-  the docker/ifcos_env toolchain, then wire them into a checkout for
-  running C++-dependent parts of the test suite (geometry, the SWIG
-  wrapper stub, the C++ parser). Use whenever a task needs to compile
-  IfcOpenShell's C++ core rather than just read/patch source - e.g.
-  reproducing or fixing a bug in src/ifcgeom, src/ifcparse, src/ifcwrap,
-  or validating util/scripts/validate_stub.py against the actual
-  generated wrapper.
----
-
-# Building IfcOpenShell locally with docker/ifcos_env
-
-`docker/` mirrors the project's GitHub Actions build environment locally,
-in a persistent, non-root container with ccache so repeat builds are fast.
-See `docker/README.md` for the design rationale. Pure-Python changes don't
-need any of this - only reach for it when you need a real compiled
-`_ifcopenshell_wrapper*.so` or `IfcConvert` binary.
-
-## Placement
-
-This `docker/` folder must live as a direct child of the repo root you want
-to build (sibling of `src/`, `cmake/`, etc.) - `compose.yaml` and
-`ifcos_env` resolve the repo via `../` relative to wherever `docker/`
-itself sits, and bind-mount it into the container. If you're setting this
-up in a fresh clone, copy the whole `docker/` directory there first.
-
-## Setup
-
-```bash
-cd docker
-./ifcos_env create   # build the image (shared by name across all your clones/checkouts, so usually instant after the first time anywhere)
-./ifcos_env up        # create + start the container, clone/unpack the third-party dependency cache (~10GB, one-time per container)
-./ifcos_env build     # full build: all deps + IfcParse + IfcGeom + IfcConvert + the Python wrapper, for one Python version
-```
-
-`PY_TGT` and `UNIQUE_ID` live in `docker/.env` - `PY_TGT` (e.g. `py-311`)
-restricts the build to one Python version instead of building five;
-`UNIQUE_ID` is a hash of the folder path, recalculated on every `up`, so
-each checkout gets its own container/volumes automatically.
-
-A full first build takes ~1.5 hours (mostly compiling IfcOpenShell's own
-C++, not the cached third-party deps). After that, ccache makes incremental
-rebuilds of a couple of touched `.cpp` files **under a minute**.
-
-## Container lifecycle
-
-The container is long-lived (`sleep infinity`) so exec'd commands and
-ccache state persist between builds. Commands map directly onto Docker
-Compose's own container-vs-image distinction:
-
-```bash
-./ifcos_env up         # create the container if it doesn't exist, then start it (runs ready_repo too)
-./ifcos_env stop       # stop the container, keep it around
-./ifcos_env start      # start it back up (same container, same filesystem layer)
-./ifcos_env restart    # stop, then start
-./ifcos_env down       # remove the container (and its network) entirely
-./ifcos_env recreate   # down, then up - a fresh container
-```
-
-Named volumes (`ccache`) and the bind-mounted repo/`build/` are unaffected
-by `down`/`recreate` - only the container itself goes away, and `up`
-recreates it from the image.
-
-## Fast iteration
-
-Pass a target to `build` to skip the parts you don't need:
-
-```bash
-./ifcos_env build IfcConvert           # only the executables (IfcConvert, IfcGeomServer) - skips the Python wrapper entirely
-./ifcos_env build IfcOpenShell-Python  # only the SWIG Python wrapper - skips executables entirely
-./ifcos_env build                      # no target = everything (needed the first time, or after touching shared headers)
-```
-
-Use this to keep the edit -> rebuild -> test loop fast when debugging: if
-you're only touching `src/ifcgeom/`, build `IfcConvert`; if you're only
-exercising the Python API, build `IfcOpenShell-Python`.
-
-## Where the artifacts land
-
-Build output goes to `<repo_root>/build/Linux/x86_64/install/` on the host
-(bind-mounted, not just inside the container), owned by you (see
-"Container user" below):
-
-- `ifcopenshell/bin/IfcConvert` - the CLI binary
-- `python-<version>/lib/python<X.Y>/site-packages/ifcopenshell/_ifcopenshell_wrapper*.so`
-  and `ifcopenshell_wrapper.py` - the compiled wrapper + its generated
-  Python glue
-
-## Testing against a checkout (automated / AI-driven)
-
-`_ifcopenshell_wrapper*.so` and `ifcopenshell_wrapper.py` are already
-gitignored under `src/ifcopenshell-python/ifcopenshell/`, which is exactly
-where a normal in-tree build would put them - copy the two files there:
-
-```bash
-SRC=build/Linux/x86_64/install/python-3.11.8/lib/python3.11/site-packages/ifcopenshell
-cp "$SRC/_ifcopenshell_wrapper.cpython-311-x86_64-linux-gnu.so" src/ifcopenshell-python/ifcopenshell/
-cp "$SRC/ifcopenshell_wrapper.py" src/ifcopenshell-python/ifcopenshell/
-```
-
-Then, to run the test suite against it:
-
-```bash
-export PATH="$PWD/build/Linux/x86_64/install/ifcopenshell/bin:$PATH"   # for IfcConvert-dependent tests
-cd src/ifcopenshell-python/test
-PYTHONPATH="$PWD/.." python3.11 -m pytest -p no:pytest-blender .
-```
-
-(`-p no:pytest-blender` avoids the pytest-blender plugin trying to find a
-`blender` executable and failing collection entirely, even for non-Blender
-tests.) You'll need the matching Python version's `pip install`s too
-(numpy, shapely, isodate, lark, tabulate, pytest, ... - whatever the
-modules under test import) since this is a bare interpreter, not the
-project's pixi env.
-
-**This is the pattern to use for automated or AI-driven verification.**
-Don't use `try` (below) for that - it overwrites files in a real, live
-Blender installation, which isn't something an automated/AI workflow
-should ever do without the human explicitly asking for it in the moment.
-
-## Testing in Blender itself (human only)
-
-`try` copies the built wrapper straight into your actual Blender/Bonsai
-extension install, for manual in-Blender testing:
-
-```bash
-./ifcos_env try
-```
-
-It reads `BLENDER_USER_RESOURCE` from `.env` - set this to wherever
-Blender's user resource folder for the Bonsai extension actually lives on
-your system, which depends on your own Blender setup:
-
-```bash
-# in docker/.env
-BLENDER_USER_RESOURCE=~/.config/blender/bonsai/
-```
-
-`try` figures out the built Python version from `build/.../install/`
-(disambiguating with `PY_TGT` if more than one version was built) and
-copies the wrapper to
-`$BLENDER_USER_RESOURCE/extensions/.local/lib/python<X.Y>/site-packages/ifcopenshell/`.
-
-## Container user
-
-The image runs as a non-root `builder` user, UID/GID matching your host
-account (passed as `--build-arg` by `create` from `id -u`/`id -g`, so it
-adjusts automatically - no manual flag needed even if you're not 1000:1000).
-Files the build creates under the bind mount come out owned by you, not
-root. Passwordless `sudo` is available inside the container (e.g. via
-`attach`) for the rare case you need root for something ad hoc.
-
-If you're picking up an existing checkout that was previously built with
-an older, root-based image, you may hit `Permission denied` the first time
-you run `up`/`build` under the new image - `build/`, `.git/modules/`, the
-`ccache` volume, `output/`, and `build.log` can all be left root-owned from
-before. Fix it once via the container's own root (no host `sudo` needed):
-
-```bash
-docker exec -u root -w /__w/IfcOpenShell/IfcOpenShell <container-name> \
-    chown -R "$(id -u)":"$(id -g)" .git/modules build output build.log /ccache
-```
-
-(`<container-name>` is `ifcopenshell-<UNIQUE_ID>` - see `docker ps -a`.)
-
-## Other things worth knowing
-
-- **Linux x64 only.** `compose.yaml` pins `platform: linux/amd64`; on an
-  ARM host (e.g. Apple Silicon) this build isn't available.
-- **The final "Package .zip archives" step of `build()` has a pre-existing
-  bash syntax error**, unrelated to compilation - the actual build already
-  succeeded by that point (look for `Built IfcOpenShell...` in the output),
-  so this is safe to ignore if you only need the raw artifacts under
-  `build/.../install/`, not packaged release zips.
-- **`test_mmaped_stream` and similar `USE_MMAP`-dependent tests will fail**
-  against this build - `nix/build-all.py` is invoked with `USE_MMAP=OFF`
-  here. Not a bug in your code if you see it fail.
-- Only the bind-mounted `<repo>/build` lives on the host filesystem your
-  repo is checked out on. Anything the container writes *outside* that
-  mount lives in the container's own writable layer under Docker's data
-  root (commonly `/var/lib/docker`, i.e. usually your root partition) -
-  keep an eye on `df -h /` if you're running several of these containers
-  at once.

+
+## Problem
+
+Linked IFC models (`bim.link_ifc`) had several gaps that made them hard to use as a
+"reference in other trades' models" workflow:
+
+- One shared `.ifc.cache.blend` per IFC file meant the **same file could not be linked
+  twice with different selector queries** — both links showed whichever query was cached
+  first in-session, and whichever was cached last after reopening (Blender reuses one
+  library datablock per path).
+- The selector query was not durably stored anywhere in the host IFC, so save → reopen
+  lost or cross-wired the filter; a scripted `bpy.ops.bim.reload_link()` also wiped it.
+- Linked geometry got **flat diffuse-only materials** — external `.blend` styles
+  (`IfcExternallyDefinedSurfaceStyle`) and per-layer materials (layerset slicing) that
+  the normal import applies were ignored.
+- Moving a linked model required an explicit enable-edit → move → save dance on the
+  active link only, with save/cancel buttons in the panel header.
+- The Explore tool's highlight broke (GPU type errors), drew at the link's *original*
+  location when the link had been moved, and `bim.append_inspected_linked_element`
+  placed appended elements at the original location too.
+
+## Key facts established
+
+- **Cache architecture**: `LoadLink.link_ifc` generates a Python script and runs a
+  background Blender subprocess that executes `bim.load_linked_project` and saves a
+  `.ifc.cache.blend`. The host session then *links* (not appends) the `IfcProject/...`
+  collection from that blend and instances it via an empty (the link "handle").
+  Georeferencing metadata lives in a sidecar `.cache.json`; extracted properties in
+  `.cache.sqlite` (whole file, query-independent — deliberately shared across queries).
+- **Blender reuses an in-session library per path.** Loading the same blend path twice
+  yields the same library/collection. This is what broke multi-query linking with a
+  shared cache filename, and why per-query *filenames* (not cache invalidation) are the
+  fix.
+- **Last-used operator properties** are reused on the next *interactive* invocation
+  (UI button), while scripted `bpy.ops` calls always start from defaults. LoadLink's
+  internal `self.query = link.query` fallback assignment was remembered by Blender and
+  leaked into the next button click (`operator_query='IfcWindow'` for the door link).
+  Any `is_property_set()`-based logic is corrupted the same way. Fix: `SKIP_SAVE` on
+  volatile props. **A GUI-only bug like this is invisible to scripted repro** — both
+  headless and windowed `--python` test runs passed while the manual flow failed.
+- **`IfcDocumentReference`** per link: attribute index 1 (`Identification`) already
+  stores the link's 4×4 transformation (existing Bonsai convention). `Description`
+  (IFC4+; **absent in IFC2X3**) now stores the selector query. One
+  `IfcDocumentInformation` (Scope `LINKED_MODEL`) per file, one reference per link.
+- **Geometry iterator materials**: `material.instance_id()` is the STEP id of the
+  `IfcSurfaceStyle` — or of an `IfcMaterial` when the item has a material but no style,
+  hence the `is_a("IfcSurfaceStyle")` guard when resolving external styles.
+- **External styles**: `IfcExternallyDefinedSurfaceStyle.Location` (`.blend`, relative
+  paths resolve against the *linked* IFC, not the host) + `Identification` in
+  `data_block_type/name` form (e.g. `materials/Brick`), same convention as
+  `bim.activate_external_style`.
+- **Chunk pipeline dedups materials by RGBA color** (`np.unique` on a color array), so
+  style identity must ride along as an extra column to survive — added only for styles
+  that actually resolve to an external material, so plain colored styles dedupe exactly
+  as before.
+- **`slice_layerset_mesh` needs a local-space, per-element mesh** (bisect planes are in
+  object space), which the chunk path can't provide (world-space, many elements per
+  mesh) — hence routing multi-layer elements through the instanced path. Its
+  `dissolve_limit` produces **ngons**, which broke the Explore highlight's
+  triangles-from-`polygon.vertices` assumption downstream.
+- **ID properties round-trip as `IDPropertyArray`**, not plain lists (verified in
+  4.5.7: empty list → flat `IDPropertyArray`; nested lists → list of `IDPropertyArray`
+  items), and `GPUIndexBuf` rejects them — selection geometry must be converted to
+  plain tuples on read.
+- **`scene.ray_cast` returns the hit instance's world matrix** (link empty matrix
+  included). For instanced occurrence objects the object's own local matrix is *not*
+  identity, so resolving the instancing empty must compare against
+  `empty.matrix_world @ obj.matrix_world`, not the empty's matrix alone.
+- **Link matrix math**: the handle empty's matrix is `inv(L) @ T @ G` (L = host local
+  matrix from georef props, T = stored transformation, G = linked model's global
+  matrix from the cache json). The world-space displacement of a moved link is
+  therefore `inv(L) @ T @ L` — no json read needed (`calculate_link_delta_matrix`).
+- **Undo consistency of auto-saved moves**: Blender undo of a handle move fires another
+  depsgraph update, so the handler re-saves the reverted matrix — stored state stays
+  consistent without transactions (a handler can't open one).
+
+## Design
+
+### Per-query caches + query persistence (multi-linking)
+
+`tool.Project.get_link_cache_paths(filepath, query)` appends `.md5(query)[:8]` to the
+cache blend/json names; the empty query keeps the legacy un-suffixed names so existing
+caches stay valid. Every cache-path consumer goes through it — `link_ifc` build and
+invalidation, the subprocess json write, model-origin/georef indicator reads,
+`calculate_link_matrix`, `save_link_transformation`, and the per-link
+selectability/wireframe/visibility toggles (which match collections *by library
+filepath* and would otherwise affect every link of the file at once).
+
+The query persists on each link's `IfcDocumentReference.Description` (written by
+`LinkIfc` and `ReloadLink`); `load_linked_models_from_ifc` restores from it, with a
+legacy-JSON fallback that only applies when the file has a **single** link (with
+several links the shared JSON can't say which link it belonged to). IFC2X3 hosts have
+no `Description` — custom queries are not restorable there (accepted).
+
+`LoadLink`/`ReloadLink` volatile properties are `SKIP_SAVE` (see key facts). Cache
+clearing tolerates a missing blend (a reload with a brand-new query points at a
+not-yet-existing filename).
+
+### Include/Exclude filter pair
+
+The selector grammar's only cross-group combiner is `+` (union) and the `parent`
+facet cannot express "not under X" (its `!=`/regex paths also match by GlobalId, so
+negation removes everything with any parent), which makes set differences like
+"group members minus the slabs under aggregate X" structurally inexpressible in one
+query string. Links therefore carry an **Exclude** query beside the include —
+mirroring `EPset_Drawing`'s Include/Exclude pattern: final set = include (or the
+default set when empty) − exclude, applied in `LoadLinkedProject` and per link in
+`create_drawing`.
+
+- **Cache key**: `get_link_cache_paths` hashes `md5(query + "\0" + exclude)` when an
+  exclude exists; include-only filters keep the pre-exclude `md5(query)` so existing
+  caches stay valid; empty filter keeps legacy un-suffixed names. Keying on query
+  alone would let same-include/different-exclude links silently serve each other's
+  geometry.
+- **Persistence**: `encode_link_filter`/`decode_link_filter` — a plain include is
+  stored in `Description` as-is (backwards compatible); an exclude, a `loaded`
+  state or a custom display name promotes the value to
+  `{"include": …, "exclude": …, "loaded": …, "name": …}` JSON. Decode treats
+  non-JSON as a legacy include string. The display name (`Link.display_name`,
+  double-click the list row to rename; file path shows as placeholder while
+  unset) exists to tell apart several links of the same file.
+- Exclude applies on top of the **default** element set too, so
+  "everything except X" needs no explicit include.
+- UI labels are **Include**/**Exclude** (matching the drawing pattern), but the
+  property identifier stays `query` for script (`bpy.ops.bim.link_ifc(query=…)`)
+  and persistence compatibility.
+- Verified headless: `query=""`/`exclude="IfcDoor"` loads only the window;
+  same file with a different filter gets its own cache; both filters survive
+  save → reopen → reload.
+
+### Auto-load on open
+
+Links that were **loaded and visible** at IFC save time auto-load when the project
+is reopened. `ExportIFC` calls `tool.Project.update_linked_models_state()`, which
+rewrites each reference's `Description` with a `loaded` flag
+(`is_loaded and not is_hidden`); `load_linked_models_from_ifc` replays flagged
+links via `load_link` after restoring the list (missing files warn and skip so
+they can't break project open). The flag extends the same JSON blob as the
+exclude — plain legacy strings decode as no-autoload. Trade-off: project open
+pays the link-load cost up front (fast on cache hit; a missing cache rebuilds in
+a background Blender, same as clicking Load). Verified headless: loaded+visible
+auto-loads; unloaded and loaded-but-hidden links stay unloaded.
+
+### Long-term serialization target: STEP Part 21 Edition 3
+
+STEP p21e3 defines the standards-track version of this feature's persistence:
+`ANCHOR`/`REFERENCE` sections (clauses 9–10) let one file import entities from
+another via URI + fragment, and **anchor tags** (`{tagname: value}`) are the
+designated slot for out-of-schema metadata — a cleaner home than the
+`Description` JSON blob (see the review-round discussion). ifcopenshell does not
+implement these sections yet ([#668](https://github.com/IfcOpenShell/IfcOpenShell/issues/668),
+open, unassigned); if it ever does, the migration path is: link →
+`REFERENCE` to the linked file's project anchor, filter/transform/loaded
+metadata → anchor tags. Keeping the blob behind
+`encode_link_filter`/`decode_link_filter` makes that a two-function change.
+
+Two p21e3 design points this branch already conforms to:
+
+- **Identity**: p21e3 distinguishes volatile file-scoped entity numbers
+  (`#100` fragments) from durable anchors/UUIDs — the same lesson behind our
+  STEP-id collision fixes (GUID-based matching, `element.file` guards). Raw
+  STEP ids must never cross a file boundary; IFC GlobalIds map 1:1 onto
+  p21e3 UUID anchors.
+- **Transport** (clause A.4): exchange structures plus referenced resources
+  can ship as one ZIP archive with references resolving inside it. Our posix,
+  optionally relative `Location`s resolved via `resolve_uri` are exactly the
+  invariants a future "package project with links" export would need.
+
+Even full p21e3 support would not cover per-link transforms, filters, or load
+state — a `REFERENCE` imports entities, it does not place a model — so the
+app-level metadata remains; only its container would change.
+
+### External styles + layerset slicing in the linked loader
+
+`LoadLinkedProject.get_external_material(style_id)` resolves a style id → appended
+Blender material from the external `.blend`, cached two ways (per style id; per
+appended data-block, so styles sharing one material don't append duplicates). Appended
+materials get their stale `ifc_definition_id` cleared (the source `.blend` may have
+been authored in a Bonsai session; the id would be misread in the linked file *and*
+in the host once the cache links in). Applied in both loading paths — instanced
+occurrences directly, chunks via the style-id column.
+
+Multi-layer elements (`IfcMaterialLayerSetUsage`, >1 layer) route through the
+instanced path and get `slice_layerset_mesh`, which gained a pluggable
+`style_to_material` resolver (defaults to the old `tool.Ifc.get_object` for the normal
+import) — the linked resolver prefers the external material, falling back to a flat
+diffuse from the style's shading colour. Also fixed there: newly appended layer
+materials are registered in the dedup dict (two layers sharing one style used to
+append it twice).
+
+Trade-off: layered walls become individual instanced objects instead of chunk members;
+meshes shared between elements (same geometry id) bake the slice from the first
+element's layerset usage — same behaviour as the normal importer.
+
+### Reload Link dialog
+
+`bim.reload_link` now exposes File Path (+ browse button), Use Relative Path
+(defaulting to the stored path form), Use Cache (default off = old always-rebuild
+behaviour), the False Origin Mode project props, and Query. A file browser can't open
+from inside a props dialog, so the browse button runs `bim.select_link_filepath`
+(fileselect) which *reopens* the reload dialog with the chosen path, carrying the
+in-progress dialog state through the round trip (op props are baked at draw time).
+Path changes update `link.name`/`filepath` and, with a host IFC, the reference
+`Location` + document name — which is why `ReloadLink` became a `tool.Ifc.Operator`.
+Script calls without arguments preserve all stored link values via `is_property_set`.
+
+`bim.reload_all_links` (refresh button beside Link IFC in the panel header) reloads
+every *loaded* link via argument-less `reload_link` calls — each link's stored
+path/query/exclude replay and its cache rebuilds from disk. Unloaded links are left
+alone. Deliberately expensive: one background cache rebuild per link.
+
+### Per-row lock toggle + auto-saved transforms
+
+Link editing moved from the panel header into each list row as a lock/unlock icon:
+unlock (`bim.enable_editing_link`) frees the handle; **any movement is persisted
+immediately** by a `depsgraph_update_post` handler (lazy — ticks without transform
+updates cost ~nothing); lock (`bim.disable_editing_link`) saves and locks.
+`bim.edit_link` and the explicit save step are **removed**; cancel/restore semantics
+no longer exist (undo or move it back). The save math lives in
+`tool.Project.save_link_transformation`. Enable/disable take a `link_index`
+(default −1 = active link) so several links can be edited at once and script calls
+stay compatible.
+
+### Explore tool + append fixes for moved links
+
+- Highlight triangles come from `mesh.calc_loop_triangles()` filtered to the queried
+  element's polygon range (ngon-safe); edges keep `polygon.edge_keys` (no diagonals).
+- `get_selected_geometry` converts the ID-prop round trip to plain tuples (GPU
+  rejects `IDPropertyArray`); TRIS drawing gated on its own data.
+- `QueryLinkedElement` passes the ray-cast instance matrix through;
+  `find_obj_root` compares it against `empty @ obj_local` and falls back to the
+  collection's only instance when no matrix is available (select-by-GUID flow).
+- `bim.append_inspected_linked_element` pre-multiplies the imported object's matrix by
+  `calculate_link_delta_matrix(link)`, matching the link by the queried instance's
+  root empty first (filepath alone is ambiguous with several links per file). The
+  element's IFC placement syncs to the moved location on save — intended.
+
+### Drawings (`create_drawing`) — moved links and per-link queries
+
+- The linework serializer opened linked IFCs raw, so a moved link's elements were
+  drawn at their *original* coordinates (usually outside the drawing extents —
+  "linked objects disappear from prints after moving the link").
+- The stored link transformation is already the **model-space** delta (that is how
+  `save_link_transformation` derives it), which is exactly the space the serializer
+  works in — so it can be baked straight into the geometry iterator via the existing
+  `model-offset`/`model-rotation` settings. The mapping composes
+  `Trans(model-offset) @ Rot(model-rotation)` (see `mapping.cpp`), matching the
+  `Trans(t) @ Rot(R)` decomposition of the rigid link matrix; `model-rotation` is a
+  quaternion passed as `(x, y, z, w)`. The pre-existing 2mm plan-view Z-offset simply
+  adds onto the translation (translations commute).
+- The serialization loop previously collected files in a dict keyed by filepath, which
+  **collapsed same-file links into one pass** (one transform — the last link's — and
+  no query awareness): with two links of one file, only one showed in the drawing.
+  It now iterates one entry per link (`(path, file, transform, query)` tuples), and
+  intersects each link's drawing elements with
+  `ifcopenshell.util.selector.filter_elements(ifc, link.query)` so the drawing shows
+  what that link actually displays in the viewport.
+- `tool.Project.get_link_transformation_matrix(link)` is the shared accessor for the
+  stored 4×4 (None when identity/absent).
+- Verified headless with the window/door kit: moved window offset in the SVG by
+  exactly 5m × scale; unmoved door at its native position; both links present.
+
+### Drawings — `.cut` styling for linked models (BISECT cut mode)
+
+- The default **BISECT** cut mode deletes the OpenCASCADE serializer's cut linework
+  (`remove_cut_linework`) and regenerates cuts by bisecting **Blender mesh objects**
+  (`generate_bisect_linework` over `context.visible_objects`). Linked models are
+  instanced collections with no mesh objects, so their cuts were deleted and never
+  regenerated — linked elements only ever appeared as `projection`, and the `.cut`
+  CSS rule never applied to them. Long-standing gap, unrelated to moved links
+  (A/B-tested against pre-branch code: identical).
+- Fix: `remove_cut_linework` only removes cut groups whose guid resolves in the
+  **host** file — linked elements keep the serializer's cut geometry, which the
+  merge step then classes as `cut`.
+- **Cross-file STEP-id collision**: `tool.Ifc.get_object(linked_entity)` resolves the
+  entity's STEP id against the *host* session's id map and can return an arbitrary
+  host object (in the test project: the drawing camera, crashing
+  `generate_material_layers` with "expected 'Mesh' found 'Camera'"). Guarded via
+  `element.file is tool.Ifc.get()` in `generate_material_layers` and the merge step.
+- **Paint order**: the projection-under-cut convention was enforced only in
+  OPENCASCADE mode (`move_projection_to_bottom`); BISECT appends its own cut paths
+  last so it never needed it — but the retained serializer cuts of linked models are
+  emitted *before* the projections. BISECT now runs the same pass; `BringToFront`
+  (`move_elements_to_top`) still gets the final say.
+- Known limitation: linked cut paths are raw serializer output — they skip the
+  shapely path-closing/merging and the material-layer hatching pass (both need host
+  Blender objects). Stroke + fill from `.cut` CSS apply; layered hatching inside
+  linked cuts is a candidate follow-up.
+- Debugging note: merged cut groups carry member guids as CSS *classes*, not as the
+  `ifcopenshell:guid` attribute — inspect both when checking cut output.
+
+## Deferred refactors (deliberate)
+
+- **Upstream `exclude=` on `filter_elements`** — the include−exclude set difference
+  is hand-rolled twice (links, drawings) because the selector grammar has no
+  difference operator and `parent` negation is broken by design (its `!=`/regex
+  paths also match GlobalIds, so negation strips everything that has a parent).
+  The right home is an `exclude=` parameter on
+  `ifcopenshell.util.selector.filter_elements`, documented in
+  `selector_syntax.rst` together with the `parent`-negation limitation. Deferred
+  to a separate ifcopenshell-python PR (different review audience; would widen
+  this PR mid-review). Once it lands, both Bonsai call sites collapse.
+- **Core/tool ceremony skipped** — the new `tool.Project` methods have no
+  `core/tool.py` interface declarations and no `bonsai/core` orchestration
+  functions, matching the pre-existing linked-model code (which bypasses the
+  core layer wholesale; `LoadLinkedProject` is flagged "prototyping" upstream).
+  Interfaces nobody calls through wouldn't add testability — the pure helpers
+  (`encode_link_filter`/`decode_link_filter`, `get_link_cache_paths`) are
+  covered directly in `test/tool/test_project.py` instead. Revisit if the
+  linked-model subsystem is ever promoted out of prototype status.
+
+## Review round 1 (PR #8242, falken10vdl) — decisions
+
+- **Path-form mismatch → duplicate documents (confirmed bug, fixed).**
+  `get_linked_models_documents()` keyed documents by the *stored* `Location`, so
+  linking the same file first relative then absolute (or vice versa) created a second
+  `IfcDocumentInformation`. Both sides of the lookup now normalize through
+  `tool.Ifc.resolve_uri()` before matching.
+- **`Description` for the query — kept.** It is implementation metadata in an IFC
+  attribute, but consistent with the existing convention on these same references
+  (`Identification` stores the 4×4 transformation, a bigger stretch). References are
+  Bonsai-managed (`Scope="LINKED_MODEL"`), so user-description collisions are unlikely.
+  A cleaner consolidated convention (query + transform + options in one serialized
+  attribute) is a candidate follow-up, deliberately out of scope here.
+- **`md5(query)[:8]` — kept.** 32 bits ≈ birthday collision at ~65k distinct queries
+  *per file*; and a collision is not silent: the cache JSON stores the full query and
+  `should_clear_cache()` compares it, so a colliding cache is detected and rebuilt
+  (self-healing).
+- **Depsgraph autosave vs save-on-lock — autosave kept.** Save-on-lock alone loses the
+  "what you see is what's saved" guarantee (move + save project without locking =
+  silently dropped move) and loses undo tracking (undo fires a depsgraph update that
+  re-saves the reverted transform). The handler early-outs when no links exist and only
+  works on ticks containing an object-transform update while a link is unlocked.
+
+## Status — implemented (verified in Blender, incl. headless + GUI repro runs)
+
+Six commits on `Linked_File_Features`:
+
+- `0096c0f6a2` reload_link without a query preserves the stored one.
+- `40db55e52d` external styles + layerset slicing for linked models
+  (`project/operator.py`, `tool/loader.py`).
+- `d210d4c814` full Reload Link dialog + `bim.select_link_filepath`.
+- `3dc161f0f2` per-row lock toggle, auto-save handler, `edit_link` removed
+  (`project/operator.py`, `project/ui.py`, `project/__init__.py`, `tool/project.py`).
+- `0571d22855` Explore highlight (ngons, IDPropertyArray), moved-link highlight,
+  append placement (`tool/project.py`, `project/operator.py`, `project/decorator.py`).
+- `c14592ec0a` per-query caches, Description persistence, SKIP_SAVE.
+
+Plus:
+
+- `ee43ed5526` review-round path normalization in `get_linked_models_documents` /
+  `LinkIfc` (see Review round 1).
+- `1669cbcd43` drawing support for moved links and per-link queries in
+  `create_drawing` (`drawing/operator.py`, `tool/project.py`).
+- `.cut` styling for linked models in BISECT cut mode + STEP-id collision guards +
+  paint order (`drawing/operator.py`) — committed together with this note update.
+
+End-to-end verified with a two-links-one-file kit (window/door, distinct queries):
+correct visuals on load, after save → reopen → reload, in both headless and windowed
+Blender.
+
+## Things to test / verify
+
+- **IFC2X3 host**: `Description` doesn't exist — link queries silently not restored on
+  reopen (legacy fallback only for single-link files). Acceptable? Warn?
+- **Relative-path links** (`use_relative_path`) through the whole cycle: cache paths,
+  reference `Location`, reload path change, query restore. The duplicate-document case
+  (same file linked relative then absolute) is fixed — verify one document with two
+  references via `IfcDocumentInformation.HasDocumentReferences`.
+- Same file linked twice, **both moved differently**: Explore highlight and append
+  placement per instance (root-empty matching), per-link visibility toggles.
+- External styles with **image textures**: paths relative to the style's source
+  `.blend` may not resolve from the cache blend's location (shared limitation with the
+  normal import path).
+- Stale cache orphans: per-query filenames accumulate one blend+json pair per distinct
+  query next to the IFC; nothing auto-deletes them. Cleanup on unlink? Document?
+- Mid-drag auto-save writes the IFC reference outside Bonsai's transaction system —
+  confirm no undo-stack weirdness in longer editing sessions.
+- Layerset slicing on meshes shared by elements with *different* usages (offset/sense)
+  bakes the first element's slice — same as normal import, but worth a look with types.
+- `bim.select_link_filepath` round trip when the reload dialog was opened for a
+  non-active link, and dialog-state carry-over after editing the query *then* browsing.
+- **Drawing SVG guid cache vs moved links**: `create_drawing` skips elements whose
+  guids already exist in the drawing's SVG (`cached_linework`, invalidated only for
+  *edited host objects*). Moving a link does not invalidate its elements, so a
+  regenerated drawing keeps their old positions until the SVG is deleted. Candidate
+  fix: subtract a moved link's guids from `cached_linework` (compare stored transform
+  against the one recorded at last generation).
+- Same element appearing in two links of one file (overlapping queries) serializes
+  twice with different transforms; the SVG guid cache keeps whichever came first on
+  regeneration. Degenerate case — probably fine to ignore, but note it.
