Ship one preset cache per vendor in place of the profile JSONs
Each vendor's system presets serialize into a single <vendor>.opc built at package time, and a shipped build carries that file alone — the profile JSON and its sub-file tree are pruned. The vendor loader, the setup wizard's profile list and the resource installer all read a vendor through its cache, falling back to parsing whenever one is absent, stale or unreadable, so the cache stays an optimization and never a source of truth. Caches hold presets in source form and resolve inheritance at load, through the same code the JSON path uses.

# Build the per-vendor system preset caches (one <vendor>.opc per vendor) by
|
||||
# running the generate_system_cache dev tool against a profiles directory, and
|
||||
# make every profiles directory named on the command line ship-ready: install
|
||||
# the caches into it and delete the preset JSONs they replace, so a build ships
|
||||
# one copy of its presets instead of two.
|
||||
#
|
||||
# ./scripts/build_preset_cache.sh # caches into resources/profiles
|
||||
# ./scripts/build_preset_cache.sh -b build/arm64 # search this build tree for the tool
|
||||
# ./scripts/build_preset_cache.sh <dir> [<dir> ...] # and ship into these profiles dirs
|
||||
#
|
||||
# Caches are generated into the source tree's resources/profiles, which is what
|
||||
# every packaging step copies from. Shipping deletes, so it is a CI packaging
|
||||
# step: pass packaged output directories, or the checkout of a build that is
|
||||
# about to be packaged from it.
|
||||
#
|
||||
# A vendor's own <vendor>.json goes along with its preset JSONs: the cache
|
||||
# carries the vendor profile and the version it was built at, so discovery,
|
||||
# version checks and installing all read it there. A shipped vendor is its cache
|
||||
# and nothing else. Only a vendor that has a cache is pruned, so an ungenerated
|
||||
# vendor keeps its JSONs and is simply parsed at startup; non-vendor JSONs
|
||||
# (blacklist.json) are left alone, as are the vendor directories themselves —
|
||||
# thumbnails, covers and bed models still live there.
