-# AGENTS.md
-
-Guidelines for AI coding agents contributing to IfcOpenShell. This file is
-intended to be read by all AI agents regardless of platform (Claude Code,
-Copilot, Cursor, etc.) in addition to any tool-specific configuration files.
-
-Human contributors using AI tools should also read this document carefully,
-as they are responsible for ensuring their contributions comply with these
-guidelines.
-
-## Project Overview
-
-IfcOpenShell is an open source library for working with Industry Foundation
-Classes (IFC). It provides C++ and Python APIs, geometry processing, and an
-ecosystem of tools including IfcConvert and the Bonsai Blender add-on.
-
-## Licensing
-
-All contributions must be compatible with the project's licensing:
-
- **Library code** (everything except Bonsai): **LGPL-3.0-or-later**
- **Bonsai** (`src/bonsai/`): **GPL-3.0-or-later**
-
-There is no Contributor License Agreement (CLA). By submitting a pull request,
-you agree that your contribution is licensed under the applicable license above.
-
-## Indicating AI-Generated Code
-
-Contributors must clearly indicate when code has been generated or
-substantially written by an AI tool.
-
-### Commits
-
-Commits that modify existing code must include a note in the **body** of the
-commit message (not the subject line) indicating that the change was
-AI-generated. For example:
-
-```
-Fix off-by-one error in element iteration
-
-The loop termination condition was incorrect when processing
-IfcRelAggregates relationships.
-
-Generated with the assistance of an AI coding tool.
-```
-
-### New Files
-
-New files that are AI-generated must include a comment near the top of the
-file indicating this. Use the appropriate comment syntax for the language:
-
-```python
-# This file was generated with the assistance of an AI coding tool.
-```
-
-```cpp
-// This file was generated with the assistance of an AI coding tool.
-```
-
-### Pull Requests
-
-Pull requests containing AI-generated code must indicate in the PR description
-which parts of the contribution are AI-generated. If the entire PR is
-AI-generated, state that clearly. If only specific commits or files are
-AI-generated, identify them.
-
-## Pull Request Guidelines
-
-### Scope and Size
-
- Each pull request should address a **single issue or feature**.
- Do not mix unrelated changes (e.g., bug fixes with refactoring or style
-  changes) in the same PR.
- Large pull requests should be broken down into **multiple small, standalone
-  commits** that are each easy to review independently. Rewrite commit history
-  for this purpose if necessary.
- PRs that are minimal, focused solutions to a specific problem are much more
-  likely to be accepted.
-
-### What to Avoid
-
- **Over-engineering**: Do not add features, abstractions, or configurability
-  beyond what is needed to solve the immediate problem.
- **Scope creep**: Do not make changes to files or code that are not directly
-  related to the task at hand.
- **Unnecessary additions**: Do not add docstrings, comments, type annotations,
-  or error handling to code you did not otherwise need to change.
- **Cosmetic changes**: Do not reformat, rename, or reorganize code that is
-  unrelated to your change.
-
-## Commit Messages
-
- The **subject line** must be **50 characters or less**.
- Use the **imperative mood** (e.g., "Fix crash in geometry kernel", not
-  "Fixed crash" or "Fixes crash").
- A commit message can be a single line if the purpose is obvious from the
-  subject alone.
- Otherwise, add a blank line after the subject followed by a short explanation
-  of a few lines in the body.
-
-## Code Style
-
-### Python
-
- **Line length**: 120 characters
- **Formatter**: black
- **Linter**: ruff
- Configuration is in `pyproject.toml`
-
-### C++
-
- **Standard**: C++17 minimum
- **Formatter**: clang-format (configuration in `.clang-format`)
- **Linter**: clang-tidy (configuration in `.clang-tidy`)
-
-Run linters and formatters **before submitting** your pull request. Do not rely
-on CI to catch formatting issues.
-
-## Testing
-
- Pull requests with test coverage are **much more likely to be merged**.
- If tests are appropriate and feasible for your change, they should be
-  included.
- Tests are not required for every change (e.g., documentation-only changes),
-  but the expectation is that testable code changes come with tests.
- Python tests use **pytest** and are located in `test/` or `tests/` directories
-  within each package under `src/`.
- Run the existing test suite for the package you modified before submitting.
-
-## Architecture Quick Reference

-# Linked file features — queries, styles, transforms, and multi-linking for linked IFC models
-
-> **Living dev note** for the `Linked_File_Features` branch/PR. Read before working
-> on the feature; append decisions and findings as the PR is refined. This is *not* user
-> documentation — at merge it is removed or its durable parts promoted to code comments.
-> See [README.md](README.md) for the convention (introduced on the
-> `opening-template-on-type` branch; not yet on this branch's base).
-
-## 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.

-The OFL allows the licensed fonts to be used, studied, modified and
-redistributed freely as long as they are not sold by themselves. The
-fonts, including any derivative works, can be bundled, embedded,

-names are not used by derivative works. The fonts and derivatives,
-however, cannot be released under any other type of license. The
-requirement for fonts to remain under this license does not apply
-to any document created using the fonts or their derivatives.
