The ccache named volume had no explicit name, so Docker Compose
namespaced it under the per-checkout project name (derived from
UNIQUE_ID), giving each checkout its own cache even though
docker/README.md already documented them as shared. Give the volume
a fixed name so all checkouts attach the same one.
Measured cache size after a full build (IfcParse+IfcGeom+IfcConvert+
wrapper, one Python version) is ~300MB, only ~5% of the previous 5G
cap. Shrink CCACHE_MAXSIZE to 2G, which comfortably covers the shared
baseline plus per-branch deltas from several diverging checkouts.

Dockerfile (renamed from Dockerfile_init, Dockerfile_update removed):
- Run as a non-root `builder` user matching the host UID/GID (passed as
--build-arg by create() from id -u/id -g), so build output under the
bind mount stays owned by the host user instead of root.
- Fix CCACHE_MAXSIZE: `ccache -M 5G` wrote its limit to a config file
under /ccache at image-build time, but /ccache is a volume mount
point, so that file gets shadowed by the (empty) volume the moment
the container actually runs - the cap never took effect. Set
CCACHE_MAXSIZE=5G as an image ENV instead.
- Dedupe ccache/libffi-devel, add --setopt=install_weak_deps=False
--setopt=tsflags=nodocs, add `git lfs install --system`, combine the
dnf update+install into one layer.
- Drop Dockerfile_update: it built FROM its own previous output, so
every `update` call made the image strictly larger forever (Docker
layers are append-only, `dnf clean` in a later layer can't shrink an
earlier one). `update` now just calls create(), which already runs
`dnf update -y` FROM a clean rockylinux:9 every time.
compose.yaml: pin platform: linux/amd64 so this doesn't silently run
under emulation on an ARM host.
ifcos_env:
- Split the previously-conflated stop/down into six distinct,
Compose-native lifecycle commands: up (create-or-start), down
(remove), stop, start, restart (stop+start, same container),
recreate (down+up, fresh container). Previously `stop` was aliased
to `down`, which silently removed the container instead of pausing
it.
- Implement try(): copies the built wrapper into a real Blender/Bonsai
install for manual testing, reading the target from a new
BLENDER_USER_RESOURCE .env variable and auto-detecting the built
Python version (disambiguating via PY_TGT for multi-version builds).
Deliberately kept human-only - it mutates a live Blender install, so
it shouldn't run unattended as part of an automated/AI workflow,
which should instead copy the wrapper into the repo's own
src/ifcopenshell-python/ifcopenshell/ (documented in SKILL.md).
- Fix unique(): the "has .env already got a UNIQUE_ID line" check
referenced an unset $FILE instead of $ENV_FILE, so it always
evaluated true and appended a fresh "UNIQUE_ID=dummy" line to .env
on every single `up`.
- Minor: differentiate remove()'s log message from down()'s (no longer
identical now that they're distinct operations), tidy help text
alignment and a stray double-space typo in clean().
SKILL.md: rewritten as current-state documentation (no more "fixed in
this copy" changelog framing) covering the above, plus a migration
note for anyone hitting root-owned leftovers from an older image.
Verified by actually building the image and driving every new
lifecycle command (stop/start/restart keep the same container ID;
down+up and recreate produce a new one) and try() (including the
quoted-tilde BLENDER_USER_RESOURCE edge case) against the real container.

First functional version, but it needs some improvements and fixes
identified as I've used it personally on one thing, and when an AI
(Claude) used it to work through the CI test errors.
I had the AI make a SKILL.md file. If the AI indicates it needs to
build the ifcopenshell binary, use this and let it rip.
