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.
