Raises the bound from -j8 to -j12: the incident dump measured 1.17 GB average per cc1plus, so 12 in flight is ~14 GB typical, well inside the 40 GB cgroup ceiling that is the real guarantee. Keeps the file byte-identical to snaporca's copy, which the header requires. Dockerfile.deps builds the deps with -j 12 for the same reason, and symlinks deps/build/destdir -> deps/build/OrcaSlicer_dep: this tree installs under the latter name while the orcacad_buildcache volume has the former baked as absolute paths in its CMakeCache. Same tree, two names — without the link, one directory rename costs a full cold rebuild.

# Rebuild the GUI binary the design rig launches — in a THROWAWAY container, writing into the
|
|
# same build-cache volume the rig's long-lived GUI container reads from.
|
|
#
|
|
# NEVER build inside the GUI container (snaporca-gui / orcacad-gui). Its baked /OrcaSlicer tree
|
|
# is the Jun-13 Snapmaker-derived source, so a `cmake .` in there silently reconfigures the
|
|
# shared build dir as project(Snapmaker_Orca) and this fork's targets vanish. That is Trap 1 of
|
|
# five; all of them, with symptoms and exact recovery commands, are in docs/rig_build_traps.md.
