-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.

-# Developer notes (in-progress features)
-
-This directory holds **living design/working notes for unmerged feature branches**,
-one Markdown file per feature, named after its branch (e.g.
-`opening-template-on-type.md`).
-
-## Purpose
-
-A shared scratchpad so collaborators — and the AI agents they work with — can pick up
-the context behind an in-progress branch: the problem, the design decisions and the
-*why*, dead ends already ruled out, and what still needs testing. Because the note is
-committed on the branch, it travels with the PR and shows up in the diff, so it is
-discoverable without anyone being told where to look.
-
-## How to use it (humans and agents)
-
- **Before working on a feature branch**, read its note here if one exists.
- **As the PR is refined**, keep the note current — append decisions, correct things
-  that changed, update the test checklist.
- **One file per feature**, named after the branch.
-
-## Lifecycle
-
-These are *not* permanent user documentation. When a PR merges, either remove its note
-or promote the durable parts (the load-bearing "why") into code comments or the regular
-docs, so stale notes do not accumulate on the default branch.

-# Profile length per-instance — typed vs per-instance length for profile types
-

-> 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.

-> Tracks feature **#8657**; depends on bug fixes **#8655** (`change_data` None) and
-> **#8656** (mapped-profile assign cascade).
-
-## Problem
-
-Revit-exported profile members (e.g. curtain-wall mullions) come in **typed-length**:
-the extrusion — including its **length** — lives on the `IfcMemberType` as an
-`IfcRepresentationMap`, and every occurrence shares it via an `IfcMappedItem`. Bonsai's
-profile tools assume each occurrence owns an editable extrusion (`IfcMemberStandardCase`
-style), so on these mapped occurrences the length UI never appears, editing/joining
-crashes, changing the type-material bleeds across all instances, and `extend_profile`
-flips the origin.
-
-Goal: make **Length** a typed-vs-per-instance property of a profile type, toggle-able in
-both directions, without corrupting the shared geometry.
-
- **Typed length** = geometry (incl. length) on the type's `RepresentationMap`;
-  occurrences `IfcMappedItem` it. One length for all instances.
- **Per-instance length** = occurrence has its **own** `SweptSolid` body + its **own**
-  `IfcMaterialProfileSetUsage`. Each instance edits its own length (`IfcMemberStandardCase`).
-
-## Key facts established
-
- **`tool.Model.get_usage_type(el)` returns `"PROFILE"` iff `el` carries an
-  `IfcMaterialProfileSet(Usage)`** (checked with `should_inherit=False`). Bonsai gates the
-  per-instance profile UI (Length control) on this. A mapped occurrence that only
-  *inherits* the type's profile set reports `None` → no Length UI. This is why un-mapping
-  must also give the occurrence its **own** `IfcMaterialProfileSetUsage`.
- **The mapped representation is shared.** `bonsai.core.geometry.remove_representation`,
-  when handed a mapped rep, resolves it and loops `get_elements_of_type` →
-  `switch_from_representation`, i.e. it **cascades to every sibling instance of the type**,
-  leaving them empty. Any code that removes an occurrence's mapped body triggers this. This
-  is the single biggest hazard and the root of most crashes we saw.
- **Typed length is spec-valid.** A plain `IfcMember` with a mapped body + a profile-set
-  usage is valid IFC (just not the `IfcMemberStandardCase` subtype). `IfcMaterialProfileSet`
-  has **no length**; length is always in the geometry. So offering typed length is a
-  legitimate mode, not a workaround (verified against local IFC4 ADD2 TC1).
- **Two origins, on opposite ends.** Revit places the object's `ObjectPlacement` origin at
-  one end of the mullion and the extrusion's own `Position` origin at the other, with the
-  object's local **+Z pointing away** from the sweep (local Z runs `-depth → 0`).
-  `get_profile_axis` (object bound-box local-Z range) + `DumbProfileJoiner.recreate_profile`
-  (which plants the new origin at `body[0]` = min-local-Z) then relocate the origin to the
-  far end on extend/join — the "flip". Natively-authored profiles run local Z `0 → depth`,
-  so `body[0]` is already the origin and nothing moves.
- **`create_profile` double-bodies mapped types.** `assign_type` (default
-  `should_map_representations=True`) maps the type's shared body onto a new occurrence, then
-  `DumbProfileGenerator.create_profile` adds a per-instance extrusion on top → two Body reps
-  / typed-by-default.
- The wrapper/core were **not** the cause of the crashes we chased for a while — a
-  `git reset --hard v0.8.0` reproduced clean, our applied changes reproduced the crash. The
-  installed environment is now matched (repo source + release wrapper `3e7b739`, via
-  `dev_environment.py`).
-
-## Design
-
-Two explicit operators + a Type-panel toggle, plus defaults/guards so the mapped hazard is
-never hit implicitly.
-
- **`bim.make_profile_length_per_instance`** (un-map; `MakeProfileLengthPerInstance`):
-  1. Copy the mapped extrusion items into a new per-instance `SweptSolid` body, **keeping
-     the shared `IfcProfileDef`** (`copy_deep(..., exclude=["IfcProfileDef"])`).
-  2. **Orphan** the old mapped body (retarget the product shape, do **not** delete it) —
-     deleting cascades to siblings, and the raw delete dangles Bonsai's Blender-side links.
-  3. Give the occurrence its **own** `IfcMaterialProfileSetUsage` (else no Length UI).
-  4. **Normalize placement**: if the object's local +Z points away from the sweep (origin at
-     the max-local-Z end), flip 180° about local X and rebuild the extrusion via
-     `add_profile_representation` so local Z runs `0 → depth` from the (unchanged) origin.
-     This is what stops `extend_profile` flipping the origin.
-  - Idempotent / repair-capable: re-running adds a missing usage to an already-un-mapped
-    occurrence. Only identity mapping transforms are handled (others are skipped).
- **`bim.make_profile_length_type_driven`** (re-map; `MakeProfileLengthTypeDriven`):
-  drop the occurrence's own usage, then `ifcopenshell.api.type.map_type_representations` to
-  map the type's shared geometry back on. If the type has **no** `RepresentationMap`
-  (Bonsai-authored profile type), first **promote** a copy of the occurrence's body onto the
-  type as a `RepresentationMap` (so the first toggled occurrence defines the type's length;
-  siblings snap to it).
- **UI toggle** (`type/ui.py` `draw_product_ui`, `type/data.py`, `type/prop.py`): a single
-  **Per-instance Length** checkbox. Backed by a `get`/`set` `BoolProperty`
-  (`length_per_instance`) — `get` reads the current mode from cached `TypeData` flags
-  (`is_typed_length_profile` / `can_make_length_type_driven`), `set` runs the matching
-  operator. No stored state to desync.
- **New occurrences default to per-instance** (`DumbProfileGenerator.create_profile`): after
-  `assign_type`, drop the inherited mapped reps so only the per-instance extrusion remains.
-  No-op for types without a `RepresentationMap`.
- **`recreate_profile` mapped guard** (`DumbProfileJoiner.recreate_profile`): if the body is
-  mapped, **skip** the per-instance rebuild (leaving typed geometry alone — a length-driven
-  type should stay typed) **but `switch_representation` to reload** so the Blender mesh
-  reflects a just-mapped type's geometry. This kills the "assign a length-driven type ⇒
-  Failed to set value + sibling turns empty" cascade *and* keeps the typed display fresh.
-  Fixes issue **#8656**.
- **`assign_type` preserves per-instance** (`core/type.py`): if the occurrence is already
-  per-instance (own non-mapped body + own profile usage), pass
-  `should_map_representations=False` so reassigning a type keeps its own geometry/length
-  instead of converting it to typed.
- **…but that flag gates the material usage too** (`core/type.py`): in `api type.assign_type`
-  the `map_material_usages` call sits *inside* the same `if should_map_representations:`
-  block. Suppressing the mapping therefore also suppressed the step that re-points the
-  occurrence's `IfcMaterialProfileSetUsage` at the new type's set, leaving a usage whose
-  `ForProfileSet` still referenced the **old** type. `get_material(should_skip_usage=True)`
-  follows that pointer, so the material panel showed — and edited — the old type's profile:
-  duplicate a profile type, change the copy's profile, and the *original's* profile was
-  rewritten instead, taking every other occurrence of the original with it. This is the
-  "revisit if reassigning across different profiles" caveat that used to sit here, and it
-  bit in the wild.
-  Fixed by re-pointing the usage in `core/type.py` immediately after the `ifc.run`. Reuse
-  `material.assign_material` rather than setting `ForProfileSet` by hand: its
-  `update_representation_profile` rewrites `SweptArea` to the new type's profile but never
-  touches the extrusion depth, so the per-instance length this whole branch exists to
-  protect still survives. `restore_material_usage_attributes` runs after it and lands on the
-  new usage. Covered by `test/bim/module/type/test_assign_type_material_usage.py`.
-
-## Supporting bug fixes (separate from the feature)
-
- **`tool/geometry.py` `change_data`** — guard `has_data_users`/`delete_data` against a
-  `None` `old_data` (empty→mesh reload path). Real Bonsai bug, exposed by the re-map reload;
-  filed as **#8655** — worth its own commit.
- **`ifcopenshell/util/placement.py` `get_axis2placement`** — numpy-2.x `x.resize(3)` fix
-  for 2D `RefDirection`. **Duplicate of open PRs #8307 / #8586** — kept locally only so
-  profile editing works during testing; **do not commit**, drop when #8307 merges.
-
-## Dead ends (ruled out)
-
- Auto-un-mapping during `type.assign_type`/`regenerate_profile` → sibling cascade. Un-map
-  is an **explicit** action only.
- Deriving depth from `obj.bound_box` for un-map → unreliable when several instances share a
-  Blender mesh; use the copied extrusion / native rebuild instead.
- Blaming the compiled wrapper / core (`3e7b739`) for the profile crashes — it was our code.
-
-## Test checklist / what's left before merge
-
- [ ] **Strip debug prints**: `make_length_per_instance` / `make_length_type_driven`,
-      `DumbProfileJoiner.recreate_profile` + `get_profile_axis`, and `core/type.py`
-      `assign_type`.
- [ ] Un-map a mullion → own length, Length UI, geometry unchanged, siblings untouched.
- [ ] `extend_profile('T')` on an un-mapped mullion → origin **stays** (no flip).
- [ ] Toggle checkbox both ways → round-trips; typed snaps to type length.
- [ ] New occurrence of a mapped type → defaults to per-instance.
- [ ] Assign a length-driven type to a **typed** occurrence → adopts type length, no cascade.
- [ ] Assign another type to a **per-instance** occurrence → stays per-instance, keeps length.
- [x] Reassigning across types with **different** profiles — was broken (the occurrence's
-      usage kept the old type's profile set, so editing it mutated the old type). Fixed in
-      `core/type.py`; covered by `test_assign_type_material_usage.py`.
- [ ] Edge cases untested: non-identity mapping transforms; non-centroid cardinal point vs
-      the 180° flip.
- [ ] Commit layout: feature on `1c421d0`; separate `change_data` fix; exclude `placement.py`.
